By allowing the breath to occur effortlessly, we provide ourselves the opportunity to regenerate. Although there are many directed breathing practices that specifically directs us to inhale or exhale at specific rhythms or depth to achieve certain goals, healthy breathing is whole body experience. Many focus on being paced at a specific rhythm such as 5.5 breath per minute; however, effortless breathing is dynamic and constantly changing. It is contstantly adapting to the body’s needs: sometimes the breath is slightly slower, sometimes slightly faster, sometimes slightly deeper, sometimes slightly more shallower. The breathing process is effortless. This process can be described by the Autogenic training phrase, “It breathes me” (Luthe, 1969; Luthe, 1979; Luthe & de Rivera, 2015). Read the essay by Jamie McHugh, Registered Master Somatic Movement Therapist and then let yourself be guided in this non-striving somatic approach to allow effortless 360 degree belly breathing for regeneration.
The 360 degree belly breathing by Jamie McHugh, MSMT, is a somatic exploration to experience that breathing is not just abdominal breathing by letting the belly expand forward, but a rhythmic 360 degree increase and decrease in abdominal volume without effort. This effortless breathing pattern can often be observed in toddlers when they sit peacefully erect on the floor. This pattern of breathing not only enhances gas exchange, more importantly, it enhances abdominal blood and lymph circulation.
“The usual psychodynamic foundation for the self-experience is that of hunger, not breath. The body is experienced as an alien entity that has to be kept satisfied; the way an anxious mother might experience a new baby. When awareness is shifted from appetite to breath, the anxieties about not being enough are automatically attenuated. It requires a settling down or relaxing into one’s own body. When this fluidity moves to the forefront of awareness…there is a relaxation of the tensed self…and the emergence of a simpler, breath-based self that is capable of surrender to the moment.” – Mark Epstein (2013).
The intention behind 360 Degree Belly Breathing is to access and express the movement of the breath in all three dimensions. This is the basis for all subsequent somatic explorations within the Embodied Mindfulness protocol, a body-based approach to traditional meditation practices I have developed over the past 20 years (McHugh, 2016). Embodied Mindfulness explores the inner landscape of the body with the essential somatic technologies of breath, vocalization, self-contact, stillness and subtle movement. We focus and sustain mental attention while pleasurably cultivating bodily calm and clarity as a daily practice for survival in these turbulent times. Coupled with individual variations and experimentation, this practice becomes a reliable sanctuary from overwhelm, scattered attention, and emotional turmoil.
The Central Diaphragm
The central diaphragm, a dome-shaped muscular sheath that divides the thorax (chest) and the abdomen (belly), is the primary mechanism for breathing. It is the floor for your heart and lungs and the ceiling for your belly. The central diaphragm is a mostly impenetrable divide, with a few openings through it for the aorta, vena cava and the esophagus. Each time you inhale, the diaphragm contracts and flattens out a bit as it presses down towards your pelvis. Each time you exhale, the diaphragm relaxes and floats back up towards your heart. The motion of the diaphragm impacts the barometric pressure in your chest: the downward movement of the diaphragm on the inhale pulls oxygen into your lungs, and the subsequent exhale expels carbon dioxide into the world as the diaphragm releases upwards.
The movement of the diaphragm is twofold: involuntary and voluntary. Involuntary, ordinary breathing is a homebase and a point of return. Breathing just automatically happens – you don’t have to think about it. Breathing is also voluntary; you can choose to change the tempo (quick or slow), the duration (short or long) and quality (smooth or sharp) of this movement to “charge up and chill out” at will. Knowing how to collaborate with your diaphragm, discovering your own rhythm of diaphragmatic action, and undulating between the automatic and the chosen is a foundation for physiological equilibrium and emotional “self-soothing”.
Watch these two brief videos to get a visual image of your diaphragm in motion:
Beginning Sitting Practice
“When your back becomes straight, your mind will become quiet.” – Shunryu Suzuki
What does it mean to have a “straight back”? What are the inner coordinates and outer parameters of this position in space? And what kind of environment is needed to support this uprightness? This simple orientation to sitting can create more comfort, ease and support in your structure, which will stimulate more fluidity in your breathing and your thinking.
As you sit on a chair, consider two points of focus: body and environment. Can I sit upright with ease and comfort on this chair? If not, what changes can I make with my body and how can I adapt the environment of this chair to meet my needs? Since we are all various heights, it is not surprising a one-size-fits-all chair would need adaptation. Don’t be content with your first solution – experiment until you find just the right configuration. Valuing and seeking bodily comfort and ease are simple yet profound acts of self-kindness.
Do you need to move your pelvis forward on the chair or back? If you move your pelvis back, do you get the necessary support from the back of the chair for your pelvic bowl? If the back of the chair is too far away and/or makes you lean back into space, place a small cushion or two between the back of the chair and the base of your spine. With your back supported, are your feet on the floor? If not, place a folded blanket or a cushion under them.
With pelvis and feet in place, take a few full breaths to stabilize your pelvis and let your weight drop down through your sitz bones into the chair. The upper body receives more support from the core muscles of the lower body when your center of gravity drops – you don’t have to work so hard to maintain uprightness. Finally, rock on your sitz bones forward, backward, and side-to-side. Movement awakens bodily feedback so you can feel where center is in this moment. That sense of center will continue to change throughout the duration of the practice period so feel free to periodically adjust your position.
After this initial structural orientation, the next step is attending to the combination of breath and self-contact to fill out our self-perception. Self-contact is like using a magnifying glass – focusing the mind by feeling the substance of the belly’s movement in our hands. Since the diaphragm is a 360-degree phenomenon that generates movement in our sides and our back as well as our front, spreading awareness out not only creates different patterns of muscular activation – it also changes the brain’s map of the body and how we perceive ourselves. This change of orientation over time recalibrates our alignment and how we settle in ourselves, with awareness of our back in equal proportion to our front and sides.
360-Degree Belly Breath
“To stop your mind does not mean to stop the activities of the mind. It means your mind pervades your whole body.” – Shunryu Suzuki
Read text below or be guided by the audio file or YouTube video. http://somaticexpression.com/classes/360DegreeBreathingwithJamieMcHugh.mp3
Sit comfortably and place your hands on the front of your belly. With each inhale, become aware of the forward movement of your belly swelling. Then, with each exhale, notice the release of your belly and the settling back to center. Give this action and each subsequent action at least 5-7 breath cycles. Intersperse this way of breathing with ordinary, effortless breathing by letting the body breathe automatically. Return time and again to ordinary breathing, letting go of the focus and the effort to rest in the aftermath.
Now, slide your hands to the sides of your belly. Notice with each breath cycle how your belly moves laterally out to the sides on the inhale and then settles back to center again on the exhale.
Now, slide your hands to the back of your belly. You may wish to make contact with the back of your hands instead of your palms if it is more comfortable. With each inhale, focus on the movement into the backspace – this will be much smaller than the movement to the front; and with each exhale, the movement settling back to center.
Finally, connect all three directions: your belly radiates out 360 degrees on the horizon with each inhale, simultaneously moving forward, backward, and out to both sides, and then settles inward with each exhale.
Finish with open awareness – scanning your whole inner landscape from feet to head, back to front, and center to extremities, and letting your body breathe itself, as you notice what is alive in you now.
Inhale – Belly Radiates Outwards; Exhale – Belly Settles Inwards
“The belly is an extraordinary diagnostic instrument. It displays the armoring of the heart as a tension in the belly. Trying tightens the belly. Trying stimulates judgment. Hard belly is often judging belly. Observing the relative openness or closedness of the belly gives insight into when and how we are holding (on) to our pain. The deeper our relationship to the belly, the sooner we discover if we are holding in the mind or opening into the heart.” – Steven Levine (1991)
The contact of your hands on your belly helps the mind pay attention to the subtle movement created by the inhale-exhale cycle of the diaphragm. The combination of tactility and interoceptive awareness focusing on the belly shifts attention into our “second brain” (the enteric nervous system) and signals the mind it can rest and soften. More pleasurable sensation is often accompanied by an emergent feeling of safety as you settle into sensing the rhythm of a slower, more even breath, creating a feedback loop between bodily/somatic ease and mental calm. Giving yourself some daily “breathing room” in this way can help you build the calm muscle!
Naturally, there can be hiccups along the way so it is not all unicorns and rainbows! By giving the mind bodily tasks to accomplish, particularly in relationship to deepening and expanding the movement of the breath, we ease the self into a slower, more receptive state of being. Yet, in this receptive state of ease, whatever is in the background of awareness can arise and slip through the “border control”, sometimes taking us by surprise and causing distress. Depending upon the nature of the information, there are layers of action strategies that can be progressively taken to modulate and buffer what arises:
Tether your awareness to the breath rhythm with hands on your belly to stay present as a witness. Next step up: open your eyes softly and look around to orient in your present environment. Further step up: breath flow, hands-on belly, eyes open a wee bit looking around, and adding simple movement, like rocking a bit in all directions or expressing an exhale as a sigh, a yawn or a hum.
Note: If you find your personal resources are insufficient, find a guide to work with one-on-one to discover your own individual path for increasing the “window of capacity”. Above all, be gentle with yourself – take your time – cultivate your garden – and enjoy your breath!

“If a problem is fixable, if a situation is such that you can do something about it, then there is no need to worry. If it’s not fixable, then there is no help in worrying. There is no benefit in worrying whatsoever.” ― Dalai Lama XIV
To implement the Dalai Lama’s quote is challenging. When caught up in an argument, being angry, extremely frustrated, or totally stressed, it is easy to ruminate, worry. It is much more challenging to remember to stay calm. When remembering the message of the Dalai Lama’s quote, it may be possible to shift perspective about the situation although a mindful attitude may not stop ruminating thoughts. The body typically continues to reacti to the torrents of thoughts that may occur when rehashing rage over injustices, fear over physical or psychological threats, or profound grief and sadness over the loss of a family member. Some people become even more agitated and less rational as illustrated in the following examples.
I had an argument with my ex and I am still pissed off. Each time I think of him or anticipate seeing them, my whole body tightened. I cannot stomach seeing him and I already see the anger in his face and voice. My thoughts kept rehashing the conflict and I am getting more and more upset.
A car cut right in front of me to squeeze into my lane. I had to slam on my brakes. What an idiot! My heart rate was racing and I wanted to punch the driver.
When threatened, we respond quickly in our thoughts and body with a defense reaction that may negatively affect those around us as well as ourselves. What can we do to interrupt negative stress reactions?
Background
Many approaches exist that allow us to become calmer and less reactive. General categories include techniques of cognitive reappraisal (seeing the situation from the other person’s point of view and labeling your own feelings and emotions) and stress management techniques. Practices that are beneficial include mindfulness meditation, benign humor (versus gallows humor), listening to music, taking a time out while implementing a variety of self-soothing practices, or incorporating slow breathing (e.g., heart rate variability and/or box breathing) throughout the day.
No technique fits all as we respond differently to our stressful life circumstances. For example, some people during stress react with a “tend and befriend stress response” (Cohen & Lansing, 2021; Taylor et al., 2000). This response appears to be mostly mediated by the hormone oxytocin acting in ways that sooth or calm the nervous system as an analgesic. These neurophysiological mechanisms of the soothing with the calming analgesic effects of oxytocin have been characterized in detail by Xin, et al. (2017).
The most common response is a fight/flight/freeze stress response that is mediated by excitatory hormones such as adrenalin and inhibitory neurotransmitters such as gamma amino butyric acid (GABA). There is a long history of fight/flight/freeze stress response research, which is beyond the scope of this blog with major theories and terms such as interior milleau (Bernard, 1872); homeostasis and fight/flight (Cannon, 1929); general adaptation syndrome (Selye, 1951); polyvagal theory (Porges, 1995); and, allostatic load (McEwen, 1998). A simplified way to start a discussion about stress reactions begins with the fight/flight stress response. When stressed our defense reactions are triggered. Our sympathetic nervous system becomes activated our mind and body stereotypically responds as illustrated in Figure 1.
Figure 1. An intense confrontation tends to evoke a stress response (reproduced from Peper et al., 2020).
The flight/fight response triggers a cascade of stress hormones or neurotransmitters (e.g., hypothalamus-pituitary-adrenal cascade) and produces body changes such as the heart pounding, quicker breathing, an increase in muscle tension and sweating. Our body mobilizes itself to protect itself from danger. Our focus is on immediate survival and not what will occur in the future (Porges, 2021; Sapolsky, 2004). It is as if we are facing an angry lion—a life-threatening situation—and we feel threatened and unsafe.
Rather than sitting still, a quick effective strategy is to interrupt this fight/flight response process by completing the alarm reaction such as by moving our muscles (e.g., simulating a fight or flight behavior) before continuing with slower breathing or other self-soothing strategies. Many people have experienced their body tension is reduced and they feel calmer when they do vigorous exercise after being upset, frustrated or angry. Similarly, athletes often have reported that they experience reduced frequency and/or intensity of negative thoughts after an exhausting workout (Thayer, 2003; Liao et al., 2015; Basso & Suzuki, 2017).
Becoming aware of the escalating cascades of physical, behavioral and psychological responses to a stressor is the first step in interrupting the escalating process. After becoming aware, reduce the body’s arousal and change the though patterns using any of the techniques described in this blog. The self-regulation skills presented in this blog are ideally over-learned and automated so that these skills can be rapidly implemented to shift from being stressed to being calm. Examples of skills that can shift from sympathetic neervous system overarousal to parasympathetic nervous system calm include techniques of autogenic traing (Schulz & Luthe, 1959), the quieting reflex developed by Charles Stroebel in 1985 or more recently rescue breathing developed by Richard Gevirtz (Stroebel, 1985; Gevirtz, 2014; Peper, Gibney & Holt, 2002; Peper & Gibney, 2003).
Concepts underlying the rescue techniques
- Psychophysiological principle: “Every change in the physiological state is accompanied by an appropriate change in the mental-emotional state, conscious or unconscious, and conversely, every change in the mental-emotional state, conscious or unconscious, is accompanied by an appropriate change in the physiological state” (Green et al. 1970, p. 3).
- Posture evokes memories and feelings associated with the position. When the body posture is erect and tall while looking slightly up. It is easier to evoke empowering, positive thoughts and feelings. When looking down it is easier to evoke hopeless, helpless and powerless thoughts and feelings (Peper et al., 2017).
- Healing occurs more easily when relaxed and feeling safe. Feeling safe and nurtured enhances the parasympathetic state and reduces the sympathetic state. Use memory recall to evoke those experiences when you felt safe (Peper, 2021).
- Interrupting thoughts is easier with somatic movement than by redirecting attention and thinking of something else without somatic movement.
- Focus on what you want to do not want to do. Attempting to stop thinking or ruminating about something tends to keeps it present (e.g., do not think of pink elephants. What color is the elephant? When you answer, “not pink,” you are still thinking pink). A general concept is to direct your attention (or have others guide you) to something else (Hilt & Pollak, 2012; Oded, 2018; Seo, 2023).
- Skill mastery takes practice and role rehearsal (Lally et al., 2010; Peper & Wilson, 2021).
- Use classical conditioning concepts to facilitate shifting states. Practice the skills and associate them with an aroma, memory, sounds or touch cues. Then when you the situation occurs, use these classical conditioned cues to facilitate the regeneration response (Peper & Wilson, 2021).
Rescue techniques
Coping When Highly Stressed and Agitated
- Complete the alarm/defense reaction with physical activity (Be careful when you do these physical exercises if you have back, hip, knee, or ankle problems).
- Acknowledge you have reacted and have chosen to interrupt your automatic response.
- Check whether the situation is actually a threat. If yes, then do anything to get out of immediate danger (yell, scream, fight, run away, or dial 911).
- If there is no actual physical threat, then leave the situation and perform vigorous physical activity to complete your alarm reaction, such as going for a run or walking quickly up and down stairs. As you do the exercise, push yourself so that the muscles in your thighs are aching, which focusses your attention on the sensations in your thighs. In our experience, an intensive run for 20 minutes quiets the brain while it often takes 40 minutes when walking somewhat quickly.
- After recovering from the exhaustive exercise, explore new options to resolve the conflict.
- Complete the alarm/defense reaction and evoke calmness with the S.O.S™ technique (Oded, 2023)
- Acknowledge you have reacted and have chosen to interrupt your automatic response.
- Squat against a wall (similar to the wall-sit many skiers practice). While tensing your arms and fists as shown in Figure 2, gaze upward because it is more difficult to engage in negative thinking while looking upwards. If you continue to ruminate, then scan the room for object of a certain color or feature to shift visual attention and be totally present on the visual object.
- Do this set of movements for 7 to 10 seconds or until you start shaking. Than stand up and relax hands and legs. While standing, bounce up and down loosely for 10 to 15 seconds as you become aware of the vibratory sensations in your arms and shoulders, as shown in Figure 3.
Figure 2.Defense position wall-sit to tighten muscles in the protective defense posture (Oded, 2023). Figure 3. Bouncing up and down to loosen muscles ((Oded, 2023).
- Acknowledge you have reacted and have chosen to interrupt your automatic response. Swing your arms back and forth for 20 seconds. Allow the arms to swing freely as illustrated in Figure 4.
Figure 4. Swinging the arms to loosen the body and spine (Oded, 2023).
- Rest and ground. Lie on the floor and put your calves and feet on a chair seat so that the psoas muscle can relax, as illustrated in Figure 5. Allow yourself to be totally supported by the floor and chair. Be sure there is a small pillow under your head and put your hand on your abdomen so that you can focus on abdominal breathing.
Figure 5. Lying down to allow the psoas muscle to relax and feel grounded (Oded, 2023).
- While lying down, imagine a safe place or memory and make it as real as possible. It is often helpful to listen to a guided imagery or music. The experience can be enhanced if cues are present that are associated with the safe place, such as pictures, sounds, or smells. Continue to breathe effortlessly at about six breaths per minute. If your attention wanders, bring it back to the memory or to the breathing. Allow yourself to rest for 10 minutes.
In most cases, thoughts stop and the body’s parasympathetic activity becomes dominant as the person feels safe and calm. Usually, the hands warm and the blood volume pulse amplitude increases as an indicator of feeling safe, as shown in Figure 6.
Figure 6. Blood volume pulse increases as the person is relaxing, feels safe and calm.
Coping When You Can’t Get Away (adapted from Peper, Harvey & Faass, 2020)
In many cases, it is difficult or embarrassing to remove yourself from the situation when you are stressed out such as at work, in a business meeting or social gathering.
- Become aware that you have reacted.
- Excuse yourself for a moment and go to a private space, such as a restroom. Going to the bathroom is one of the only acceptable social behaviors to leave a meeting for a short time.
- In the bathroom stall, do the 5-minute Nyingma exercise, which was taught by Tarthang Tulku Rinpoche in the tradition of Tibetan Buddhism, as a strategy for thought stopping (see Figure 7). Stand on your toes with your heels touching each other. Lift your heels off the floor while bending your knees. Place your hands at your sides and look upward. Breathe slowly and deeply (e.g., belly breathing at six breaths a minute) and imagine the air circulating through your legs and arms. Do this slow breathing and visualization next to a wall so you can steady yourself if necessary to keep balance. Stay in this position for 5 minutes or longer. Do not straighten your legs—keep squatting despite the discomfort. In a very short time, your attention is captured by the burning sensation in your thighs. Continue. After 5 minutes, stop and shake your arms and legs.
Figure 7. Stressor squat Nyingma exercise (reproduced from Peper et al., 2020).
- Follow this practice with slow abdominal breathing to enhance the parasympathetic response. Be sure that the abdomen expands as the inhalation occurs. Breathe in and out through the nose at about six breaths per minute.
- Once you feel centered and peaceful, return to the room.
- After this exercise, your racing thoughts most likely will have stopped and you will be able to continue your day with greater calm.
What to do When Ruminating, Agitated, Anxious or Depressed
(adapted from Peper, Harvey, & Hamiel, 2019).
- Shift your position by sitting or standing erect in a power position with the back of the head reaching upward to the ceiling while slightly gazing upward. Then sniff quickly through nose, hold and again sniff quickly then very slowly exhale. Be sure as you exhale your abdomen constricts. Then sniff again as your abdomen gets bigger, hold, and sniff one more time letting the abdomen get even bigger. Then, very slow, exhale through the nose to the internal count of six (adapted from Balban et al., 2023). When you sniff or gasp, your racing thoughts will stop (Peper et al., 2016).
- Continue with box breathing (sometimes described as tactical breathing or battle breathing) by exhaling slowly through your nose for 4 seconds, holding your breath for 4 seconds, inhaling slowly for 4 seconds through your nose, holding your breath for 4 seconds and then repeating this cycle of breathing for a few minutes (Röttger et al., 2021; Balban et al., 2023). Focusing your attention on performing the box breathing makes it almost impossible to think of anything else. After a few minutes, follow this with slow effortless diaphragmatic breathing at about six breaths per minute. While exhaling slowly through your nose, look up and when you inhale imagine the air coming from above you. Then as you exhale, imagine and feel the air flowing down and through your arms and legs and out the hands and feet.
- While gazing upward, elicit a positive memory or a time when you felt safe, powerful, strong and/or grounded. Make the positive memory as real as possible.
- Implement cognitive strategies such as reframing the issue, sending goodwill to the person, seeing the problem from the other person’s point of view, and ask is this problem worth dying over (Peper, Harvey, & Hamiel, 2019).
What to Do When Thoughts Keep Interrupting
Practice humming or toning. When you are humming or toning, your focus is on making the sound and the thoughts tend to stop. Generally, breathing will slow down to about six breaths per minute (Peper, Pollack et al., 2019). Explore the following:
- Box breathing (Röttger et al., 2021; Balban et al., 2023)
- Humming also known as bee breath (Bhramari Pranayama) (Abishek et al., 2019; Yoga, 2023) – Allow the tongue to rest against the upper palate, sit tall and erect so that the back of the head is reaching upward to the ceiling, and inhale through your nose as the abdomen expands. Then begin humming while the air flows out through your nose, feel the vibration in the nose, face and throat. Let humming last for about 7 seconds and then allow the air to blow in through the nose and then hum again. Continue for about 5 minutes.
- Toning – Inhale through your nose and then vocalize a single sound such as Om. As you vocalize the lower sound, feel the vibration in your throat, chest and even going down to the abdomen. Let each toning exhalation last for about 6 to 7 seconds and then inhale through your nose. Continue for about 5 minutes (Peper, al., 2019).
Many people report that after practice these skills, they become aware that they are reacting and are able to reduce their automatic reaction. As a result, they experience a significant decrease in their stress levels, fewer symptoms such as neck and holder tension and high blood pressure, and they feel an increase in tranquility and the ability to communicate effectively.
Practicing these skills does not resolve the conflicts; they allow you to stop reacting automatically. This process allows you a time out and may give you the ability to be calmer, which allows you to think more clearly. When calmer, problem solving is usually more successful. As phrased in a popular meme, “You cannot see your reflection in boiling water. Similarly, you cannot see the truth in a state of anger. When the waters calm, clarity comes” (author unknown).

Is mindfulness training old wine in new bottles?

This extensive blog discusses the benefits of mindfulness-based meditation (MM) techniques and explores how similar beneficial outcomes occur with other mind-centered practices such as transcendental meditation, and body-centered practices such as progressive muscle relaxation (PMR), autogenic training (AT), and yoga. For example, many standardized mind-body techniques such as mindfulness-based stress reduction and mindfulness-based cognitive therapy (a) are associated with a reduction in symptoms of symptoms such as anxiety, pain and depression. This article explores the efficacy of mindfulness based techniques to that of other self-regulation techniques and identifies components shared between mindfulness based techniques and several previous self-regulation techniques, including PMR, AT, and transcendental meditation. The authors conclude that most of the commonly used self-regulation strategies have comparable efficacy and share many elements.
Mindfulness-based strategies are based in ancient Buddhist practices and have found acceptance as one of the major contemporary behavioral medicine techniques (Hilton et al, 2016; Khazan, 2013). Throughout this blog the term mindfulness will refer broadly to a mental state of paying total attention to the present moment, with a non-judgmental awareness of the inner and/ or outer experiences (Baer et al., 2004; Kabat-Zinn, 1994).
In 1979, Jon Kabat-Zinn introduced a manual for a standardized Mindfulness-Based Stress Reduction (MBSR) program at the University of Massachusetts Medical Center (Kabat-Zinn, 1994, 2003). The eight-week program combined mindfulness as a form of insight meditation with specific types of yoga breathing and movements exercises designed to focus on awareness of the mind and body, as well as thoughts, feelings, and behaviors.
There is a substantial body of evidence that mindfulness-based cognitive therapy (MBCT); Teasdale et al., 1995) and mindfulness-based stress reduction (MBSR) (Kabat-Zinn, 1994, 2003) have combined with skills of cognitive therapy for ameliorating stress symptoms such as negative thinking, anxiety and depression. For example, MBSR and MBCT has been confirmed to be clinical beneficial in alleviating a variety of mental and physical conditions, for people dealing with anxiety, depression, cancer-related pain and anxiety, pain disorder, or high blood pressure (The following are only a few of the hundred studies published: Andersen et al., 2013; Carlson et al., 2003; Fjorback et al., 2011; Greeson, & Eisenlohr-Moul, 2014; Hoffman et al., 2012; Marchand, 2012; Baer, 2015; Demarzo et al., 2015; Khoury et al, 2013; Khoury et al, 2015; Chapin et al., 2014; Witek Janusek et al., 2019). Currently, MBSR and MBCT techniques that are more standardized are widely applied in schools, hospitals, companies, prisons, and other environments.
The Relationship Between Mindfulness and Other Self-Regulation Techniques
This section addresses two questions: First, how do mindfulness-based interventions compare in efficacy to older self-regulation techniques? Second, and perhaps more basically, how new and different are mindfulness-based therapies from other self-regulation-oriented practices and therapies?
Is mindfulness more effective than other mind/body body/mind approaches?
Although mindfulness-based meditation (MM) techniques are effective, it does not mean that is is more effective than other traditional meditation or self-regulation approaches. To be able to conclude that MM is superior, it needs to be compared to equivalent well-coached control groups where the participants were taught other approaches such as progressive relaxation, autogenic training, transcendental meditation, or biofeedback training. In these control groups, the participants would be taught by practitioners who were self-experienced and had mastered the skills and not merely received training from a short audio or video clip (Cherkin et al, 2016). The most recent assessment by the National Centere for Complementary and Integrative Health, National Institutes of Health (NCCIH-NIH, 2024) concluded that generally “the effects of mindfulness meditation approaches were no different than those of evidence-based treatments such as cognitive behavioral therapy and exercise especially when they include how to generalize the skills during the day” (NCCIH, 2024). Generalizing the learned skills into daily life contributes to the successful outcome of Autogenic Training, Progressive Relaxation, integrated biofeedback stress management training, or the Quieting Response (Luthe, 1979; Davis et al., 2019; Wilson et al., 2023; Stroebel, 1982).
Unfortunately, there are few studies that compare the effective of mindfulness meditation to other sitting mental techniques such as Autogenic Training, Transcendental Meditation or similar meditative practices that are used therapeutically. When the few randomized control studies of MBSR versus autogenic training (AT) was done, no conclusions could be drawn as to the superior stress reduction technique among German medical students (Kuhlmann et al., 2016).
Interestingly, Tanner, et al (2009) in a waitlist study of students in Washington, D.C. area universities practicing TM used the concept of mindfulness, as measured by the Kentucky Inventory of Mindfulness Skills (KIM) (Baer et al, 2004) as a dependent variable, where TM practice resulted in greater degrees of ‘mindfulness.’ More direct comparisons of MM with body-focused techniques, such as progressive relaxation, or Autogenic training mindfulness-based approaches, have not found superior benefit. For example, Agee et al (2009) compared the stress management effects of a five-week Mindfulness Meditation (MM) to a five-week Progressive Muscle Relaxation (PMR) course and found no meaningful reports of superiority of one over the other program; both MM and PMR were effective in reducing symptoms of stress.
In a persuasive meta-analysis comparing MBSR with other similar stress management techniques used among military service members, Crawford, et al (2013) described various multimodal programs for addressing post-traumatic stress disorder (PTSD) and other military or combat-related stress reactions. Of note, Crawford, et al (2013) suggest that all of the multi-modal approaches that include Autogenic Training, Progressive Muscle Relaxation, movement practices including Yoga and Tai Chi, as well as Mindfulness Meditation, and various types of imagery, visualization and prayer-based contemplative practices ALL provide some benefit to service members experiencing PTSD.
An important observation by Crawford et al (2013) pointed out that when military service members had more physical symptoms of stress, the meditative techniques appeared to work best, and when the chief complaints were about cognitive ruminations, the body techniques such as Yoga or Tai Chi worked best to reduce symptoms. Whereas it may not be possible to say that mindfulness meditation practices are clearly superior to other mind-body techniques, it may be possible to raise questions about mechanisms that unite the mind-body approaches used in therapeutic settings.
Could there be negative side effects?
Another point to consider is the limited discussion of the possible absence of benefit or even harms that may be associated with mind-body therapies. For example, for some people, meditation does not promote prosocial behavior (Kreplin et al, 2018). For other people, meditation can evoke negative physical and/or psychological outcomes (Lindahl et al, 2017; Britton et al., 2021). There are other struggles with mind-body techniques when people only find benefit in the presence of a skilled clinician, practitioner, or guru, suggesting a type of psychological dependency or transference, rather than the ability to generalize the benefits outside of a set of conditions (e.g. four to eight weeks of one to four hour trainings) or a particular setting (e.g. in a natural and/or quiet space).
Whereas the detailed instructions for many mindfulness meditation trainings, along with many other types of mind-body practices (e.g. Transcendental Meditation, Autogenic Training, Progressive Muscle Relaxation, Yoga, Tai Chi…) create conditions that are laudable because they are standardized, a question is raised as to ‘critical ingredients’, using the metaphor of baking. The difference between a chocolate and a vanilla cake is not ingredients such as flour, or sugar, etc., which are common to all cakes, but rather the essential or critical ingredient of the chocolate or vanilla flavoring. So what are the essential or critical ingredients in mind-body techniques? Extending the metaphor, Crawford, et al (2013, p. 20) might say the critical ingredient common to the mind-body techniques they studied was that people “can change the way their body and mind react to stress by changing their thoughts, emotions, and behaviors…” with techniques that, relatively speaking, “involve minimal cost and training time.”
The skeptical view suggested here is that MM techniques share similar strategies with other mind-body approaches that encouraging learners to ‘pay attention and shift intention.’ This strategy is part of the instructions when learning Progressive Relaxation, Autogenic Training, Transcendental Meditation, movement meditation of Yoga and Tai Chi and, with instrumented self-regulation techniques such as bio/neurofeedback. In this sense, MM training repackages techniques that have been available for millennia and thus becomes ‘old wine sold in new bottles.’
We wonder if a control group for compassionate mindfulness training would report more benefits if they were asked not only to meditate on compassionate acts, but actually performed compassionate tasks such as taking care of person in pain, helping a homeless person, or actually writing and delivering a letter of gratitude to a person who has helped them in the past? The suggestion is to titrate the effects of MM techniques, moving from a more basic level of benefit to a more fully actualized level of benefit, generalizing their skill beyond a training setting, as measured by the Baer et al (2004) Kentucky Inventory of Mindfulness Skills.
Each generation of clinicians and educators rediscover principles without always recognizing that the similar principles were part of the previous clinical interventions. The analogies and language has changed; however, the underlying concepts may be the same. Mindfulness interventions are now the new, current and popular approach. Some of the underlying ‘mindfulness’ concepts that are shared in common with successfully other mind-body and self-regulation approaches include:
The practitioner must be self-experienced in mindfulness practice. This means that the practitioners do not merely believe the practice is effective; they know it is effective from self-experience. Inner confidence conveyed to clients and patients enhances the healing/placebo effect. It is similar to having sympathy or empathy for clients and patients that occurs from have similar life experiences, such as when a clinician speaks to a patient. For example, a male physician speaking to a female patient who has had a mastectomy may be compassionate; however, empathy occurs more easily when another mastectomy patient (who may also be a physician) shares how she struggled overcame her doubts and can still be loved by her partner.
There may also be a continuum of strengthening beliefs about the benefits of mindfulness techniques that leads to increase benefits for the approach. Knowing there are some kinds of benefits from initiating a practice of mindfulness increases empathy/compassion for others as they learn. Proving that mindfulness techniques are causing benefits after systematically comparing their effectiveness with other approaches strengthens the belief in the mindfulness approaches. Note that a similar process of strengthening one’s belief in an approach occurs gradually, over time as clients and patients progress through beginner, intermediate and advanced levels of mind-body practices.
Observing thoughts without being captured. Being a witness to the thoughts, emotions, and external events results in a type of covert global desensitization and skill mastery of NOT being captured by those thoughts and emotions. This same process of non-attachment and being a witness is one of the underpinnings of techniques that tacitly and sometime covertly support learning ways of controlling attention, such as with Autogenic Training; namely how to passively attend to a specific body part without judgment and, report on the subjective experience without comparison or judgment.
Ongoing daily practice. Participants take an active role in their own healing process as they learn to control and focus their attention. Participants are often asked to practice up to one hour a day and apply the practices during the day as mini-practices or awareness cues to interrupt the dysfunctional behavior. For example in Autogenic training, trainees are taught to practice partial formula (such my “neck and shoulders are heavy”) during the day to bring the body/mind back to balance. While with Progressive Relaxation, the trainee learns to identify when they tighten inappropriate muscles (dysponesis) and then inhibit this observed tension.
Peer support by being in a group. Peer support is a major factor for success as people can share their challenges and successes. Peer support tends to promote acceptance of self-and others and provides role modeling how to cope with stressors. It is possible that some peer support groups may counter the benefits of a mind-body technique, especially when the peers do not provide support or may in fact impede progress when they complain of the obstacles or difficulties in their process.
These concepts are not unique to Mindfulness Meditation (MM) training. Similar instructions have been part of the successful/educational intervention of Progressive Relaxation, Autogenic Training, Yogic practices, and Transcendental Meditation. These approaches have been most successful when the originators, and their initial students, taught their new and evolving techniques to clients and patients; however, they became less successful as later followers and practitioners used these approaches without learning an in-depth skill mastery. For example, Progressive relaxation as taught by Edmund Jacobson consisted of advanced skill mastery by developing subtle awareness of different muscle tension that was taught over 100 sessions (Mackereth & Tomlinson, 2010). It was not simply listening once to a 20-minute audio recording about tightening and relaxing muscles. Similarly, Autogenic training is very specific and teaches passive attention over a three to six-month time-period while the participant practices multiple times daily. Stating the obvious, learning Autogenic Training, Mindfulness, Progressive Relaxation, Bio/Neurofeedback or any other mind-body technique is much more than listening to a 20-minute audio recording.
The same instructions are also part of many movement practices. For many participants focusing on the movement automatically evoked a shift in attention. Their attention is with the task and they are instructed to be present in the movement.
Areas to explore.
Although Mindfulness training with clients and patients has resulted in remarkable beneficial outcomes for the participants, it is not clear whether mindfulness training is better than well taught PR, AT, TM or other mind/body or body/mind approaches. There are also numerous question to explore such as: 1) Who drops out, 2) Is physical exercise to counter sitting disease and complete the alarm reaction more beneficial, and 3) Strategies to cope with wandering attention.
- Who drops out?
We wonder if mindfulness is appropriate for all participants as sometimes participants drop out or experience negative abreactions. It not clear who those participants are. Interestingly, hints for whom the techniques may be challenging can be found in the observations of Autogenic Training that lists specific guidelines for contra-, relative- and non-indications (Luthe, 1970).
- Physical movement to counter sitting disease and complete the alarm reaction.
Although many mindfulness meditation practices may include yoga practices, most participants practice it in a sitting position. It may be possible that for some people somatic movement practices such as a slow Zen walk may quiet the inner dialogue more quickly. In our experience, when participants are upset and highly stressed, it is much easier to let go of agitation by first completing the triggered fight/flight response with vigorous physical activity such as rapidly walking up and downs stairs while focusing on the burning sensations of the thigh muscles. Once the physical stress reaction has been completed and the person feels physically calmer then the mind is quieter. Then have the person begin their meditative practice.
- Strategies to cope with wandering attention.
Some participants have difficulty staying on task, become sleepy, worry, and/or are preoccupied. We observed that first beginning with physical movement practices or Progressive Relaxation appears to be a helpful strategy to reduce wandering thoughts. If one has many active thoughts, progressive relaxation continuously pulls your attention to your body as you are directed to tighten and let go of muscle groups. Being guided supports developing the passive focus of attention to bring awareness back to the task at hand. Once internally quieter, it is easier hold their attention while doing Autogenic Training, breathing or Mindfullness Meditation.
By integrating somatic components with the mindfulness such as done in Progressive Relaxation or yoga practices facilitates the person staying present. Similarly, when teaching slower breathing, if a person has a weight on their abdomen while practicing breathing, it is easier to keep attending to the task: allow the weight to upward when inhaling and feeling the exhalation flowing out through the arms and legs.
Therapeutic and education strategies that implicitly incorporate mindfulness
Progressive relaxation
In the United States during the 1920 progressive relaxation (PR) was developed and taught by Edmund Jacobson (1938). This approach was clinically very successful for numerous illnesses ranging from hypertension, back pain, gastrointestinal discomfort, and anxiety; it included 50 year follow-ups. Patients were active participants and practiced the skills at home and at work and interrupt their dysfunctional patterns during the day such as becoming aware of unnecessary muscle tension (dyponetic activity) and then release the unnecessary muscle tension (Whatmore & Kohli, 1968). This structured approach is totally different than providing an audio recording that guides clients and patients through a series of tightening and relaxing of their muscles. The clinical outcome of PR when taught using the original specific procedures described by Jacobson (1938) was remarkable. The incorporation of Progressive Relaxation as the homework practice was an important cofactor in the successful outcome in the treatment of muscle tension headache using electromyography (EMG) biofeedback by Budzynski, Stoyva and Adler (1970).
Autogenic Training
In 1932 Johannes Schultz in Germany published a book about Autogenic Training describing the basic training procedure. The basic autogenic procedure, the standard exercises, were taught over a minimum period of three month in which the person practiced daily. In this practice they directed theri passive attention to the following cascading sequence: heaviness of their arms, warmth of their arms, heart beat calm and regular, breathing calm and regular or it breathes me, solar plexus is warm, forehead is cool, and I am at peace (Luthe, 1979). Three main principles of autonomic training mentioned by Luthe (1979) are: (1) mental repetition of topographically oriented verbal formulae for brief periods; (2) passive concentration; and (3) reduction of exteroceptive and proprioceptive afferent stimulation. The underlying concepts of Autogenic Therapy include as described by Peper and Williams (1980):
The body has an innate capacity for self-healing and it is this capacity that is allowed to become operative in the autogenic state. Neither the trainer nor trainee has the wisdom necessary to direct the course of the self-balancing process; hence, the capacity is allowed to occur and not be directed.
- Homeostatic self-regulation is encouraged.
- Much of the learning is done by the trainee at home; hence, the responsibility for the training lies primarily with the trainee.
- The trainer/teacher must be self-experience in the practice.
- The attitude necessary for successful practice is one of passive attention; active striving and concern with results impedes the learning process. An attitude of acceptance is cultivated, letting be whatever comes up. This quality of attention is known as “mindfulness’ in meditative traditions.
The clinical outcome for autogenic therapy is very promising. The detailed guided self-awareness training and uncontrolled studies showed benefits across a wide variety of psychosomatic illness such as asthma, cancer, hypertension, anxiety, pain irritable bowel disease, depression (Luthe & Schultz, 1970a; Luthe & Schultz, 1970b). Autogenic training components have also been integrated in biofeedback training. Elmer and Alice Green included the incorporation of autogenic training phrases with temperature biofeedback for the very successful treatment of migraines (Green & Green, 1989). Autonomic training combine with biofeedback in clinical practices produced better results than control group for headache population (Luthe, 1979). Empirical research found that autonomic training was applied efficiently in emotional and behavioral problems, and physical disorder (Klott, 2013), such as skin disorder (Klein & Peper, 2013), insomnia (Bowden et al., 2012), Meniere’s disease (Goto, Nakai, & Ogawa, 2011) and the multitude of stress related symptoms (Wilson et al., 2023).
Bio/neurofeedback training
Starting in the late 1960s, biofeedback procedures have been developed as a successful treatment approach for numerous illnesses ranging from headaches, hypertension, to ADHD (Peper et al., 1979; Peper & Shaffer, 2010; Khazan, 2013). In most cases, the similar instructions that are part of mindfulness meditation are also embedded in the bio/neurofeedback instructions. The participants are instructed to learn control over some physiological parameter and then practice the same skill during daily life. This means that during the learning process, the person learn passive attention and is not be captured by marauding thoughts and feeling. and during the day develop awareness Whenever they become aware of dysfunctional patterns, thoughts, emotions, they initiated their newly learned skill. The ongoing biological feedback signals continuously reminds them to focus.
Transcendental meditation
The next fad to hit the American shore was Transcendental Meditation (TM)– a meditation practice from the ancient Vedic tradition in India. The participant were given a mantra that they mentally repeated and if their attention wanders, they go back to repeating the mantra internally. The first study that captured the media’s attention was by Wallace (1970) published in the Journal Science which reported that “During meditation, oxygen consumption and heart rate decreased, skin resistance increased, and the electroencephalogram showed specific changes in certain frequencies. These results seem to distinguish the state produced by Transcendental Meditation from commonly encountered states of consciousness and suggest that it may have practical applications.” (Wallace, 1970).
The participants were to practice the mantra meditation twice a day for about 20 minutes. Meta-analysis studies have reported that those who practiced TM as compared to the control group experienced significant improved of numerous disorders such as CVD risk factors, anxiety, metabolic syndrome, drug abuse and hypertension (Paul-Labrador et al, 2006; Rainforth et al., 2007; Hawkins, 2003).
To make it more acceptable for the western audience, Herbert Benson, MD, adapted and simplified techniques from TM training and then labelled a core element, the ‘relaxation response’ (Benson et al., 1974) Instead of giving people a secret mantra and part of a spiritual tradition, he recommend using the word “one” as the mantra. Numerous studies have demonstrated that when patients practice the relaxation response, many clinical symptoms were reduced. The empirical research found that practiced transcendental meditation caused increasing prefrontal low alpha power (8-10Hz) and theta power of EEG; as well as higher prefrontal alpha coherence than other locations at both hemispheres. Moreover, some individuals also showed lower sympathetic activation and higher parasympathetic activation, increased respiratory sinus arrhythmic and frontal blood flow, and decreased breathing rate (Travis, 2001, 2014). Although TM and Benson’s relaxation response continues to be practiced, mindfulness has taking it place.
Conclusion
Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Cognitive Therapy (MBCT) are very beneficial and yet may be considered ‘old wine in new bottles’ where the metaphor refers to millennia old meditation techniques as ‘old wine’ and the acronyms such as MBSR or MBCT as ‘new bottles’. Like many other ‘new’ therapeutic approaches or for that matter, many other ‘new’ medications, use it now before it becomes stale and loses part of its placebo power. As long as the application of a new technique is taught with the intensity and dedication of the promotors of the approach, and as long as the participants are required to practice while receiving support, the outcomes will be very beneficial, and most likely similar in effect to other mind-body approaches.
The challenge facing mindfulness practices just as those from Autogenic Training, Progressive Relaxation and Transcendental Meditation, is that familiarity breeds contempt and that clients and therapists are continuously looking for a new technique that promises better outcome. Thus as Mindfulness training is taught to more and more people, it may become less promising. In addition, as mindfulness training is taught in less time, (e.g. fewer minutes and/or fewer sessions), and with less well-trained instructors, who may offer less support and supervision for people experiencing possible negative effects, the overall benefits may decrease. Thus, mindfulness practice, Autogenic training, progressive relaxation, Transcendental Meditation, movement practices, meditation, breathing practices as well as the many spiritual practices all appear to share common fate of fading over time. Whereas the core principles of mind-body techniques are ageless, the execution is not always assured.

Rethink the monies spent on cancer screening tests
Posted: November 24, 2023 Filed under: behavior, cancer, Evolutionary perspective, healing, health, Nutrition/diet, self-healing | Tags: breast canceer, Cancer screening, environmental toxins, Life style, mammography, organic foods Leave a commentErik Peper, PhD and Richard Harvey, PhD
Cancer screening tests are based upon the rational that early detection of fatal cancers enables earlier and more effective treatments (Kowalski, 2021), however, there is some controversy. Early screening may increase the risk of over diagnosis, treating false positives (people who did not have the cancer but the test indicates they have cancer) and potentially fatal treatment of cancers that would never progress to increase morbidity or mortality (Kowalski, 2021).
Today about $40 billion spent on colon cancer screening, $15 billion spent on breast cancer screening, and $4 billion spent on prostate cancer screening annually (CSPH, 2021). A question is raised whether the billions and billions of dollars spent on screening asymptomatic participants would be more wisely spent on promoting and supporting life style changes that reduce cancer risks and actually extend life span? That cancer screening is expensive does not mean no one should be screened. Instead, the argument is that the majority of healthcare dollars could be spent on health promotion practices and reserving screening for those people who are at highest risk for developing cancers.
What is the evidence that screening prolongs life?
Cancer screening tests appear correlated with preventing deaths since deaths due to cancers in the USA have decreased by about 28% from 1999 to 2020 (CDC, 2023a). Although cancer causes many of the deaths in the USA, overall life expectancy has increased by less than 1% from 1999 to 2020. If cancer screening were more effective, the life expectancy should have increased more because cancer is the second leading cause of death (CDC, 2023b). Consider also that deaths due to cancers may be coincident and or comorbid with other circumstances. For example, during the last four years, overall life expectancy in the USA has precipitously declined in part due to other causes of death such as the COVID pandemic and opioid overdose epidemic (Lewis, 2022). Decline in life expectancy in the USA has many contributing factors, including the ‘harms’ associated with cancer screening procedures. For example, perforations during colon cancer screening can lead to internal bleeding, or complications related to surgeries, radiotherapies or chemotherapies. Bretthauer et al., (2023) commented: “A cancer screening test may reduce cancer-specific mortality but fail to increase longevity if the harms for some individuals outweigh the benefits for others or if cancer-specific deaths are replaced by deaths from competing cause” (p. 1197).
Bretthauer et al. (2023) conducted a systematic review and meta-analysis of 18 long-term randomized clinical trials involving 2.1 million Individuals with more than nine years of follow-up reporting on all-cause mortality. They reported that“…this meta-analysis suggest that current evidence does not substantiate the claim that common cancer screening tests save lives by extending lifetime, except possibly for colorectal cancer screening with sigmoidoscopy.”
Following is a summary of Bretthauer et al. (2023) findings:
- The only cancer screening with a significant lifetime gain (approximately 3 months) was sigmoidoscopy.
- There was no significant difference between harms of screening and benefits of screening for:
- mammography
- prostate cancer screening
- FOBT (fecal occult blood test) screening every year or every other year
- lung cancer screening Pap test cytology for cervical cancer screening, no randomized clinical trials with cancer-specific or all-cause mortality end points and long term follow-up were identified.
Potential for loss or harm (e.g., iatrogenic and nosocomial) versus potential for benefit and extended life
More than 35 years ago a significant decrease in breast cancer mortality was observed after mammography was implemented. The correlation suggested a causal relationship that screening reduced mortality (Fracheboud, 2004). This correlation made logical sense since the breast cancer screening test identified cancers early which could then be treated and thereby would result in a decrease in mortality.
How much money is spent on screening that may correlate with unintended harms?
The annual total expenditure for cancer screening is estimated to be between $40-$50 billion annually (CSPH, 2021). Below are some of the estimated expenditures for common tests other than colorectal cancer screening, which arguably is costly; however, has potential benefits that outweigh potential harms.
- $10.37-13.94 billion for mammography to screen 50% of eligible women (Badal et al, 2023).
- $2-4 billion for prostate cancer (Ma et al., 2014)
- $1-2 billion for lung cancer (Taylor et al., 2022)
What is the correlation between initiation of mammography and decrease in breast cancer mortality?
The conclusion that mammography reduced breast cancer mortality was based upon studies without control groups; however, this relationship could be causal or synchronistic. The ambiguity of correlation or causation was resolved with the use of natural experimental control groups. Some European countries began screening 10 years earlier than other countries. Using statistical techniques such as propensity score matching when comparing the data from countries that initiated mammography screening early (Netherlands, Sweden and Northern Ireland) to countries that started screening 10 year later (Belgium, Norway and Republic of Ireland), the effectiveness of screening could be compared.
The comparisons showed no difference in the decrease of breast cancer mortality in countries that initiated breast cancer screening early or late. For example, there was no difference in the decrease of breast cancer mortality rates of women who lived in the Netherlands that started screening early versus those who lived in Belgium that began screening 10 years later, as is shown Figure 1 (Autier et al, 2011).
Figure 1. No difference in age adjust breast cancer mortality between the two adjacent countries even though breast cancer screening began ten years earlier in the Netherlands than in Belgium (graph reproduced from Autier et al, 2011).
The observations are similar when comparing neighboring countries: Sweden (early screening) to Norway (late screening) as well as Northern Ireland, UK (early screening) compared to the Republic of Ireland (late screening). The systematic comparisons showed that screening did not account for the decrease in breast cancer mortality. To what extent could the decrease in mortality be related to other factors such as better prenatal and early childhood diet and life style, improved nutrition, reduction in environmental pollutants, and other unidentified life style and environmental factors which improve immune competence?
A simplistic model to reduce the risk of cancers is described in the following equation (Gorter & Peper, 2011).
Cancer risk can be reduced, arguably by influencing risk factors that contribute to cancers as well as increasing factors to enhance immune competence. In the simple model above, ‘Cancer burden’ refers to the set of exposures that increase the odds of cancer formations. Categories include exposures to oncoviruses, environmental exposures (e.g., ionizing radiation, carcinogenic chemicals) as well as genetic (e.g., chromosomal aberrations, replication errors) and epigenetic factors (e.g., lifestyle categories related to eating, exercising, sleeping, and relaxing). In the model above, ‘Immune competence’ refers to a set of categories of immune functioning related to DNA repair, orderly cell death (i.e., processes of apoptosis), expected autophagy, as well as ‘metabolic rewiring,’ also called cellular energetics, that would allow the body to be able to reduce manage cancers from progressing (Fouad & Aanei, 2017) .
How do we examine the cancer burden/immune competence relationship?
Schmutzler et al., (2022) have suggested personalized and precision-medicine risk-adjusted cancer screening incorporating “… high-throughput “multi-omics” technologies comprising, among others, genomics, transcriptomics, and proteomics, which have led to the discovery of new molecular risk factors that seem to interact with each other and with non-genetic risk factors in a multiplicative manner.” The argument is that ‘profit-centered’ medicine could incorporate ‘multi-omics’ into risk-adjusted cancer screening as a way to reduce potential loss or harm due to other cancer screening procedures. Rather than simply screening for cancers using currently invasive or toxic procedures which may do more harm than good, consider more nuanced screening tests aimed at the so-called ‘hallmarks of cancer?’ For example, Hanahan (2022) suggests some technical targets for the multi-omics technologies. The following are some of the precision screening tests possible topersonalized medicine of 14 factors or processes related to:
- cells evading growth suppression
- non-mutational epigenetic reprogramming
- avoiding immune destruction
- enabling replicative immortality
- tumor-promoting inflammation
- polymorphic microbiomes
- activating invasion and metastasis
- inducing or accessing vasculature formation/angiogenesis
- cellular senescence
- genome instability and mutation
- resisting cell death
- deregulating cellular metabolism
- unlocking phenotypic plasticity
- sustaining proliferative signaling
Of the listed categories above, ‘phenotypic plasticity’ (cf. Feinberg, 2007; Gupta et al., 2019) suggests that lifestyle behaviors and environmental exposures play a role in cancer progression and regression.
Lifestyle and environmental factors can contribute to the development of cancers.
The 2008-2009 report from the President’s Cancer Panel appraised the National Cancer Program in accordance with the National Cancer Act of 1971 stated (Reuben, 2010):
“We have grossly underestimated the link between environmental toxins, plastics, chemicals, and cancer risk. It is estimated that 70 percent of all cancers were related to diet and environment “
Multiple research studies have shown that a healthy life style pattern is associated with decreased cancer risks and increased longevity. Lifestyle factors that have been documented to increase cancer risks in the United Kingdom (UK) as shown in figure 2.
Figure 2. Percentages of cancer cases in the UK attributable to different exposures. Adapted from Brown et al., 2018 and reproduced by permission from Key et al., 2020.
Similar findings have been reported by Song et al. (2016) from the long term follow-up of 126901 adult health care professionals. People who never smoked, drank no alcohol or moderate alcohol (< 1 drink/d for women; < 2 drinks/d for men}, had a body-mass index (BMI) of at least 18.t but lower than 27.5, did weekly aerobic physical activity of at least 75 vigorous-intensity minutes or 150 150 moderate-intensity minutes compared to those who smoked, drank, had high BMI and did not exercise had nearly half the cancer death rate. Song et al (2016) concludes:
“…about 20% to 40% of carcinoma cases and about half of carcinoma deaths can be potentially prevented through lifestyle modification. Not surprisingly, these figures increased to 40% to 70% when assessed with regard to the population of US whites which has a much worse lifestyle pattern than other cohorts. Notably, approximately 80% to 90% of lung cancer deaths can be avoided if Americans adopted the lifestyle of the low-risk group, mainly by quitting smoking. For other cancers, a range of 10% to 70% of deaths can be prevented. These results provide strong support for the importance of environmental factors in cancer risk and reinforce the enormous potential of primary prevention for cancer control.”
Said another way, primary prevention should remain a priority for cancer control.
Given that many cancers are related to diet, environment and lifestyle, it is estimated that 50% of all cancers and cancer deaths could be prevented by modifying personal behavior. Thus, the monies spent on screening or even developing new treatments could better be spent on prevention along with implementing programs that promote a healthier environment, diet and personal behavior (AACR, 2011).
What can be done? Addressing systems not symptoms
From a ‘systems perspective,’ the first step is to reduce the cancer burden and carcinogenic agents that occur in our environment such environmental pollution (Turner et al., 2022). In many cases, governmental regulations that reduce cancer risk factors have been weakened, delayed, and contested for years through industry’s lobbying. It often takes more than 30 years after risk factors have been observed and documented before government regulations are successfully implemented, as exemplified in the battle over tobacco or, air pollution regulations related to particulates from burning fossil fuels (Stratton et al, 2001).
Sadly, we cannot depend upon governments or industries to implement regulations known to reduce cancer risks. More within our control is implementing lifestyle changes that enhance immune competence and promote health.
Implement a healthy life style that enhances immune competence and, supports health and well-being
Paraphrasing a trope of what some physicians may state: ‘Take two pills, and call me in the morning. Oh, and eat well, exercise, and get good rest.’ Broadly stated, the following are some controllable lifestyle behaviors that can decrease cancer risks and promotes health. Implementing environmental and lifestyle changes are very challenging because they are highly related to socio economic factors, cultural factors, industry push for profits over health, and self-care challenges since there are no immediate results experienced by behavior and lifestyle changes.
In many cases, the effects of harmful life-style and environment factors are only observed twenty or more years later (e.g., diabetes, lung cancer, cirrhosis of the liver). The individual does not experience immediate benefits of lifestyle changes thus it is more challenging to know that your healthy life style has an effect. The process is even more complex because in most cases it is not a single factor but the interaction of multiple factors (genetics, lifestyle, and environment). The complexity of causality so often conflicts with the simplistic research studies to identify only one isolated risk factor. Instead of waiting for the definitive governmental guidelines and regulations, adopt a ‘precautionary principle’ which means do not take an action when there is uncertainty about its potential harm (Goldstein, 2001). Do not wait for screening; instead, take charge of your health and implement as many of the following behaviors and strategies to enhance immune competence and thereby reduce cancer risks.
Eat organic foods, especially vegetable and fruits.
Many studies have suggested that eating organic foods and in particular more fruits and vegetable such as a Mediterranean diet is associated with increased health and longevity. Similarly, people who eat do not eat highly-processed or ultra-processed foods have better health status (Van Tulleken, 2023). For example, In the large prospective study of 68, 946 participants, adults who consumed the most organic fruits, vegetables, dairy products, meat and other foods had 25% fewer cancers when compared with adults who never ate organic food (Baudry et al., 2018; Rabin, 2018). Similarly, many studies have reported that those who adhere consistently to a Mediterranean diet have a significantly lower incidence of chronic diseases (such as cardiovascular diseases, diabetes, etc.) and cancers compared to those who do not adhere to a Mediterranean diet (Mentella et al., 2019).
Reduce environmental pollution exposure
Air pollution and the exposure to airborne carcinogens are a significant risk factor for cancers as illustrated by the increased cancer rates among smokers. In the USA, the reduction of smoking has significantly decreased the lung cancer deaths (US Department of Health and Human Services, 2014).
Increase movement and exercise
Many studies have documented that people who exercise regularly and are otherwise non–sedentary but are active their entire lives have the lowest risk for breast cancers and colon cancers. Women who exercise 3 hours a week or more have a 30-40% lower risk of developing breast cancer (NIH NCI, 2023). The NIH National Cancer Institute summary concludes that exercises also significantly benefited the following cancer survivors (NIH NCI, 2023):
- Breast cancer: In a 2019 systematic review and meta-analysis of observational studies, breast cancer survivors who were the most physically active had a 42% lower risk of death from any cause and a 40% lower risk of death from breast cancer than those who were the least physically active (Spei et al, 2019).
- Colorectal cancer: Evidence from multiple epidemiologic studies suggests that physical activity after a colorectal cancer diagnosis is associated with a 30% lower risk of death from colorectal cancer and a 38% lower risk of death from any cause (Patel et al., 2019).
- Prostate cancer: Limited evidence from a few epidemiologic studies suggests that physical activity after a prostate cancer diagnosis is associated with a 33% lower risk of death from prostate cancer and a 45% lower risk of death from any cause ((Patel et al., 2019).
- Implement stress management.
Chronic stress may reduce immune competence and increase the risk of cancers as well as hinders healing from cancer treatments (Dai et al., 2020). The results of numerous studies have shown that implementing stress management spractices uch as Cognitive-behavioral stress management (CBSM) improves mood and lowers distress during treatment and, is also associated with longer survival compared to control groups in the 8-15 year follow up (Stagl et al., 2015).
Respect your biological rhythm.
The International Agency for Research on Cancer (IARC) reports that, when the human circadian clock is disrupted, the likelihood of developing cancers, including lung cancers, intestinal cancers, and breast cancers, dramatically increases (Huang, et al., 2023). Go to bed at the same time and, have about 8 hours of sleep. As much as possible avoid night shifts at work along with frequent jet lag as that highly disrupts the circadian rhythm.
Increase social connections and be part of a social community
Absence of social support, feeling lonely and socially isolated tends reduces immune competence and increases cancer mortality risk while having more social support satisfaction is associated with lower mortality risks (Salazaor et al., 2023; Boen et al., 2018). Meta-analysis of 148 studies (308,849 participants) found that that on the average there is a 50% increased likelihood of survival for participants with stronger social relationships (Holt-Lunstad et al., 2010).
Live a life with meaning and purpose
Having meaning and purpose make each moment worth living and may contribute to improving immune function and possible cancer survival (LeShan, 1994; Rosenbaum & Rosenbaum, 2023).
Summary
The research suggests that cancer screening does not extend life span unless specifically performed for certain diagnostic purposes or, with individuals who are at high risk of developing cancers (e.g., have a genetic predisposition). Implementing self-care health behaviors that have been identified to promote health and increase lifespan. Implementing health behaviors is challenging since there is limited governmental and corporate support. Thus, take charge and implement a holistic self-care lifestyle that reduces cancer risk factors and supports health.

Adapted by the Well Being Journal, 32(4), 30-35. from the book, TechStress: How Technology is Hijacking Our Lives, Strategies for Coping, and Pragmatic Ergonomics by Erik Peper, Richard Harvey, and Nancy Faass.
Every year, millions of office workers in the United States develop occupational injuries from poor computer habits—from carpal tunnel syndrome and tension headaches to repetitive strain injury, such as “mouse shoulder.” You’d think that an office job would be safer than factory work, but the truth is that many of these conditions are associated with a deskbound workstyle.
Back problems are not simply an issue for workers doing physical labor. Currently, the people at greatest risk of injury are those with a desk job earning over $70,000 annually. Globally, computer-related disorders continue to be on the rise. These conditions can affect people of all ages who spend long hours at a computer and digital devices.
In a large survey of high school students, eighty-five percent experienced tension or pain in their neck, shoulders, back, or wrists after working at the computer. We’re just not designed to sit at a computer all day.
Field of Ergonomics
For the past twenty years, teams of researchers all over the world have been evaluating workplace stress and computer injuries—and how to prevent them. As researchers in the fields of holistic health and ergonomics, we observe how people interact with technology. What makes our work unique is that we assess employees not only by interviewing them and observing behaviors, but also by monitoring physical responses.
Specifically, we measure muscle tension and breathing, in the moment, in real-time, while they work. To record shoulder pain, for example, we place small sensors over different muscles and painlessly measure the muscle tension using an EMG (electromyograph)—a device that is employed by physicians, physical therapists, and researchers. Using this device, we can also keep a record of their responses and compare their reactions over time to determine progress.
What we’ve learned is that people get into trouble if their muscles are held in tension for too long. Working at a computer, especially at a stationary desk, most people maintain low-level chronic tension for much of the day. Shallow, rapid breathing is also typical of fine motor tasks that require concentration, like data entry.
Muscle tension and breathing rate usually increase during data entry or typing without our awareness.
When these patterns are paired with psychological pressure due to office politics or job insecurity, the level of tension and the risk of fatigue, inflammation, pain, or injury increase. In most cases, people are totally unaware of the role that tension plays in injury. Of note, the absolute level of tension does not predict injury—rather, it is the absence of periodic rest breaks throughout the day that seems to correlate with future injuries.
Restbreaks
All of life is the alternation between movement and rest, inhaling and exhaling, sleeping and waking. Performing alternating tasks or different types of activities and movement is one way to interrupt the couch potato syndrome—honoring our evolutionary background.
Our research has confirmed what others have observed: that it’s important to be physically active, at least periodically, throughout the day. Alternating activity and rest recreate the pattern of our ancestors’ daily lives. When we alternate sedentary tasks with physical activity, and follow work with relaxation, we function much more efficiently. In short, move your body more.
Better Computer Habits: Alternate Periods of Rest and Activity
As mentioned earlier, our workstyle puts us out of sync with our genetic heritage. Whether hunting and gathering or building and harvesting, our ancestors alternated periods of inactivity with physical tasks that required walking, running, jumping, climbing, digging, lifting, and carrying, to name a few activities. In contrast, today many of us have a workstyle that is so immobile we may not even leave our desk for lunch.
As health researchers, we have had the chance to study workstyles all over the world. Back pain and strain injuries now affect a large proportion of office workers in the US and in high-tech firms worldwide. The vast majority of these jobs are sedentary, so one focus of the research is on how to achieve a more balanced way of working.
A recent study on exercise looked at blood flow to the brain. Researchers Carter and colleagues found that if people sit for four hours on the job, there’s a significant decrease in blood flow to the brain. However, if every thirty or forty minutes they get up and move around for just two minutes, then brain blood flow remains steady. The more often you interrupt sitting with movement, the better.
It may seem obvious that to stay healthy, it’s important to take breaks and be physically active from time to time throughout the day. Alternating activity and rest recreate the pattern of our ancestors’ daily lives. The goal is to alternate sedentary tasks with physical activity and follow work with relaxation. When we keep this type of balance going, most people find that they have more energy, are more productive, and can be more effective.
Genetics: We’re Hardwired Like Ancient Hunters
Despite a modern appearance, we carry the genes of our forebearers—for better and for worse. (Art courtesy of Peter Sis). Reproduced from Peper, E., Harvey, R., & Faass (2020). TechStress: How Technology is Hijacking Our Lives, Strategies for Coping, and Pragmatic Ergonomics. Berkeley: North Atlantic Books.
In the modern workplace, most of us find ourselves working indoors, in small office spaces, often sitting at a computer for hours at a time. In fact, the average Westerner spends more than nine hours per day sitting indoors, yet we’re still genetically programmed to be physically active and spend time outside in the sunlight most of the day, like the nomadic hunters and gatherers of forty thousand years ago.
Undeniably, we inherently conserve energy in order to heal and regenerate. This aspect of our genetic makeup also helps burn fewer calories when food is scarce. Hence the propensity for lack of movement and sedentary lifestyle (sitting disease).
In times of famine, the habit of sitting was essential because it reduced calorie expenditure, so it enabled our ancestors to survive. In a prehistoric world with a limited food supply, less movement meant fewer calories burned. Early humans became active when they needed to search for food or shelter. Today, in a world where food and shelter are abundant for most Westerners, there is no intrinsic drive to initiate movement.
It is also true that we have survived as a species by staying active. Chronic sitting is the opposite of our evolutionary pattern in which our ancestors alternated frequent movement while hunting or gathering food with periods of rest. Whether they were hunters or farmers, movement has always been an integral aspect of daily life. In contrast, working at the computer—maintaining static posture for hours on end—can increase fatigue, muscle tension, back strain, and poor circulation, putting us at risk of injury.
Quit a Sedentary Workstyle
Almost everyone is surprised by how quickly tension can build up in a muscle, and how painful it can become. For example, we tend to hover our hands over the keyboard without providing a chance for them to relax. Similarly, we may tighten some of the big muscles of our body, such as bracing or crossing our legs.
What’s needed is a chance to move a little every few minutes—we can achieve this right where we sit by developing the habit of microbreaks. Without regular movement, our muscles can become stiff and uncomfortable. When we don’t take breaks from static muscle tension, our muscles don’t have a chance to regenerate and circulate oxygen and necessary nutrients.
Build a variety of breaks into your workday:
- Vary work tasks
- Take microbreaks (brief breaks of less than thirty seconds)
- Take one-minute stretch breaks
- Fit in a moving break
Varying Work Tasks
You can boost physical activity at work by intentionally leaving your phone on the other side of the desk, situating the printer across the room, or using a sit-stand desk for part of the day. Even a few minutes away from the desk makes a difference, whether you are hand delivering documents, taking the long way to the bathroom, or pacing the room while on a call.
When you alternate the types of tasks and movement you do, using a different set of muscles, this interrupts the contractions of muscle fibers and allows them to relax and regenerate. Try any of these strategies:
- Alternate computer work with other activities, such as offering to do a coffee run
- Schedule walking meetings with coworkers
- Vary keyboarding and hand movements
Ultimately, vary your activities and movements as much as possible. By changing your posture and making sure you move, you’ll find that your circulation and your energy improve, and you’ll experience fewer aches and pains. In a short time, it usually becomes second nature to vary your activities throughout the day.
Experience It: “Mouse Shoulder” Test
You can test this simple mousing exercise at the computer or as a simulation. If you’re at the computer, sit erect with your hand on the mouse next to the keyboard. To simulate the exercise, sit with erect posture as if you were in front of your computer and hold a small object you can use to imitate mousing.
With the mouse (or a sham mouse), simulate drawing the letters of your name and your street address, right to left. Be sure each letter is very small (less than half an inch in height). After drawing each letter, click the mouse.
As part of the exercise, draw the letters and numbers as quickly as possible for ten to fifteen seconds. What did you observe? In almost all cases, you may note that you tightened your mousing shoulder and your neck, stiffened your trunk, and held your breath. All this occurred without awareness while performing the task. Over time, this type of muscle tension can contribute to discomfort, soreness, pain, or eventual injury.
Microbreaks
If you’ve developed an injury—or have chronic aches and pains—you’ll probably find split-second microbreaks invaluable. A microbreak means taking brief periods of time that last just a few seconds to relax the tension in your wrists, shoulders, and neck.
For example, when typing, simply letting your wrists drop to your lap for a few seconds will allow the circulation to return fully to help regenerate the muscles. The goal is to develop a habit that is part of your routine and becomes automatic, like driving a car. To make the habit of microbreaks practical, think about how you can build the breaks into your workstyle. That could mean a brief pause after you’ve completed a task, entered a column of data, or before starting typing out an assignment.
For frequent microbreaks, you don’t even need to get up—just drop your hands in your lap or shake them out, move your shoulders, and then resume work. Any type of shaking or wiggling movement is good for your circulation and kind of fun.
In general, a microbreak may be defined as lasting one to thirty seconds. A minibreak may last roughly thirty seconds to a few minutes, and longer large-movement breaks are usually greater than a few minutes. Popular microbreaks:
- Take a few deep breaths
- Pause to take a sip of water
- Rest your hands in your lap
- Stretch
- Let your arms drop to your sides
- Shake out your hands (wrists and fingers)
- Perform a quick shoulder or neck roll
Often, we don’t realize how much tension we’ve been carrying until we become more mindful of it. We can raise our awareness of excess tension—this is a learned skill—and train ourselves to let go of excess muscle tension. As we increase our awareness, we’re able to develop a new, more dynamic workstyle that better fits our goals and schedule.
One-Minute Stretch Breaks
We all benefit from a brief break, even with the best of posture (left). One approach is to totally release your muscles (middle). That release can be paired with a series of brief stretches (right).

The typical mini-stretch break lasts from thirty seconds to a few minutes, and ideally you want to take them several times per hour. Similar to microbreaks, mini-stretch breaks are especially important for people with an injury or those at risk of injury. Taking breaks is vital, especially if you have symptoms related to computer stress or whenever you’re working long hours at a sedentary job. To take a stretch break:
Begin with a big stretch, for example, by reaching high over your head then drop your hands in your lap or to your sides.
Look away from the monitor, staring at near and far objects, and blink several times. Straighten your back and stretch your entire backbone by lifting your head and neck gently, as if there were an invisible string attached to the crown of your head.
Stretch your mind and body. Sitting with your back straight and both feet flat on the floor, close your eyes and listen to the sounds around you, including the fan on the computer, footsteps in the hallway, or the sounds in the street.
Breathe in and out over ten seconds (breathe in for four or five seconds and breathe out for five or six seconds), making the exhale slightly longer than the inhale. Feel your jaw, mouth, and tongue muscles relax. Feel the back and bottom of the chair as your body breathes all around you. Envision someone in your mind’s eye who is kind and reassuring, who makes you feel safe and loved, and who can bring a smile to your face inwardly or outwardly.
Do a wiggling movement. When you take a one-minute break, wiggling exercises are fast and easy, and especially good for muscle tension or wrist pain. Wiggle all over—it feels good, and it’s also a great way to improve circulation.
Building Exercise and Movement into Every Day
Studies show that you get more benefit from exercising ten to twenty minutes, three times a day, than from exercising for thirty to sixty minutes once a day. The implication is that doing physical activities for even a few minutes can make a big difference.
Dunstan and colleagues have found that standing up three times an hour and then walking for just two minutes reduced blood sugar and insulin spikes by twenty-five percent.Fit in a Moving Break

Once we become conscious of muscle tension, we may be able to reverse it simply by stepping away from the desk for a few minutes, and also by taking brief breaks more often. Explore ways to walk in the morning, during lunch break, or right after work. Ideally, you also want to get up and move around for about five minutes every hour.
Ultimately, research makes it clear that intermittent movement, such as brief, frequent stretching throughout the day or using the stairs rather than elevator, is more beneficial than cramming in a couple of hours at the gym on the weekend. This explains why small changes can have a big impact—it’s simply a matter of reminding yourself that it’s worth the effort.
Workstation Tips
Your ability to see the display and read the screen is key to reducing neck and eye strain. Here are a few strategic factors to remember:
Monitor height: Adjust the height of your monitor so the top is at eyebrow level, so you can look straight ahead at the screen.
Keyboard height: The keyboard height should be set so that your upper arms hang straight down while your elbows are bent at a 90-degree angle (like the letter L) with your forearms and wrists held horizontally.
Typeface and font size: For email, word processing, or web content, consider using a sans serif typeface. Fonts that have fewer curved lines and flourishes (serifs) tend to be more readable on screen.
Checking your vision: Many adults benefit from computer glasses to see the screen more clearly. Generally, we do not recommend reading glasses, bifocals, trifocals, and progressive lenses as they tend to allow clear vision at only one focal length. To see through the near-distance correction of the lens requires you to tilt your head back. Although progressive lenses allow you to see both close up and at a distance, the segment of the lens for each focal length is usually too narrow for working at the computer.
Wearing progressive lenses requires you to hold your head in a fixed position to be in focus. Yet you may be totally unaware that you are adapting your eye and head movements to sustain your focus. When that is the case, most people find that special computer glasses are a good solution.
Consider computer glasses if you must either bring your nose to the screen to read the text, wear reading glasses and find that their focal length is inappropriate for the monitor distance, wear bi- or trifocal glasses, or are older than forty.
Computer glasses correct for the appropriate focal distance to the computer. Typically, monitor distance is about twenty-three to twenty-eight inches, whereas reading glasses correct for a focal length of about fifteen inches. To determine your individual, specific focal length, ask a coworker to measure the distance from the monitor to your eyes. Provide this personal focal distance at the eye exam with your optometrist or ophthalmologist and request that your computer glasses be optimized for that distance.
Remembering to blink: As we focus on the screen, our blinking rate is significantly reduced. Develop the habit of blinking periodically: at the end of a paragraph, for example, or when sending an email.
Resting your eyes: Throughout the day, pause and focus on the far distance to relax your eyes. When looking at the screen, your eyes converge, which can cause eyestrain. Each time you look away and refocus, that allows your eyes to relax. It’s especially soothing to look at green objects such as a tree that can be seen through a window.
Minimizing glare: If the room is lit with artificial light, there may be glare from your light source if the light is right in front of you or right behind you, causing reflection on your screen. Reflection problems are minimized when light sources are at a 90-degree angle to the monitor (with the light coming from the side). The worst situations occur when the light source is either behind or in front of you.
An easy test is to turn off your monitor and look for reflections on the screen. Everything that you see on the monitor when it’s turned off is there when you’re working at the monitor. If there are bright reflections, they will interfere with your vision. Once you’ve identified the source of the glare, change the location of the reflected objects or light sources, or change the location of the monitor.
Contrast: Adjust the light contrast in the room so that it is neither too bright nor too dark. If the room is dark, turn on the lights. If it is too bright, close the blinds or turn off the lights. It is exhausting for your eyes to have to adapt from bright outdoor light to the lighting of your computer screen. You want the light intensity of the screen to be somewhat similar to that in the room where you’re working. You also do not want to look from your screen to a window lit by intense sunlight.
Don’t look down at phone: According to Kenneth Hansraj, MD, chief of spine surgery at New York Spine Surgery and Rehabilitation Medicine, pressure on the spine increases from about ten pounds when you are holding your head erect, to sixty pounds of pressure when you are looking down. Bending forward to look at your phone, your head moves out of the line of gravity and is no longer balanced above your neck and spine. As the angle of the face-forward position increases, this intensifies strain on the neck muscles, nerves, and bones (the vertebrae).
The more you bend your neck, the greater the stress since the muscles must stretch farther and work harder to hold your head up against gravity. This same collapsed head-forward position when you are seated and using the phone repeats the neck and shoulder strain. Muscle strain, tension headaches, or neck pain can result from awkward posture with texting, craning over a tablet (sometimes referred to as the iPad neck), or spending long hours on a laptop.
A face-forward position puts as much as sixty pounds of pressure on the neck muscles and spine.
Repetitive strain of neck vertebrae (the cervical spine), in combination with poor posture, can trigger a neuromuscular syndrome sometimes diagnosed as thoracic outlet syndrome. According to researchers Sharan and colleagues, this syndrome can also result in chronic neck pain, depression, and anxiety.
When you notice negative changes in your mood or energy, or tension in your neck and shoulders, use that as a cue to arch your back and look upward. Think of a positive memory, take a mindful breath, wiggle, or shake out your shoulders if you’d like, and return to the task at hand.
Strengthen your core: If you find it difficult to maintain good posture, you may need to strengthen your core muscles. Fitness and sports that are beneficial for core strength include walking, sprinting, yoga, plank, swimming, and rowing. The most effective way to strengthen your core is through activities that you enjoy.
Final Thoughts
If these ideas resonate with you, consider lifestyle as the first step. We need to build dynamic physical activity into our lives, as well as the lives of our children. Being outside is usually an uplift, so choose to move your body in natural settings whenever possible, whatever form that takes. Being outside is the factor that adds an energetic dimension. Finally, share what you learn, and help others learn and grow from your experiences.
If you spend time in front of a computeror using a mobile device, read the book, TechStress: How Technology is Hijacking Our Lives, Strategies for Coping, and Pragmatic Ergonomics. It provides practical, easy-to-use solutions for combating the stress and pain many of us experience due to technology use and overuse. The book offers extremely helpful tips for ergonomic use of technology, it
goes way beyond that, offering simple suggestions for improving muscle health that seem obvious once you read them, but would not have thought of yourself: “Why didn’t I think of that?” You will learn about the connection between posture and mood, reasons for and importance of movement breaks, specific movements you can easily perform at your desk, as well as healthier ways to utilize technology in your everyday life.

(2004). Applied psychophysiology for therapeutic use: Healing a shoulder injury, Biofeedback, 32(2), 11-18.
“It has been an occurrence of the third dimension for me! How come my pain — that lasted for more than 10 days and was still so strong that I really had difficulties in breathing, couldn’t laugh without pain nor move my arm not even to fulfil my daily routines such as dressing and eating — disappeared within one single session of 20 minutes? And not only that, I was able to freely rotate my arm as if it had never been injured before.” —23 year old woman
The participant T., aged 23, was a psychology student who participated in an educational workshop for Healthy Computing. She volunteered to be a subject for a surface electromyographic (SEMG) monitoring and feedback demonstration. Ten days prior to this workshop, she had a severe skiing accident. She described the accident as follows:
I went skiing and may be I had too much snow in my ski-binding and while turning, I slipped out of my binding and fell head first down into the hill. As I fell, I landed on my ski pole which hit my left upper chest and breast area. Afterwards, my head was humming and I assumed that I had a light concussion. I stopped skiing and stayed in bed for a while. The next day it started hurting and I couldn’t turn my head or put my shoulders back (they were rotated forward). Also, I couldn’t ski as I was not able to look down to my feet–my muscles were too contracted and I felt searing pain whenever I moved. I hoped that it would go away however, the pain and left forward shoulder rotation stayed.
Assessment
Observation and Palpation
T.´s left shoulder was rolled forward (adducted and in internal rotation). She was not able to breathe or laugh without pain or move her arm freely. All movements in vertical and horizontal directions and rotations were restricted by at least 50 % as compared to her right arm (limitations in shoulder extension, flexion and external rotation). Also, her hands were ice-cold and she breathed very shallowly and rapidly in her chest. She was not able to stand in an upright position or sit in a comfortable position without maintaining her left upper extremity in a protected position. Her left shoulder blade (scapula) was winging.
After visually observing her, the instructor placed his left hand on her left shoulder and pectoralis muscles and his right hand on the back of her shoulder. Using palpation and anchoring her back with his leg so that she could not rotate her trunk, he explored the existing range of shoulder movement. He also attempted to rotate the left shoulder outward and back–not by forcing or pulling—but by very gentle traction. No change in mobility was observed and the pectoralis muscle felt tight (SEMG monitoring is helpful to the therapist during such a diagnostic assessment by helping to identify the person’s reactivity and avoiding to evoke and condition even more bracing). T. reported afterwards that she was very scared by this assessment because there was one point in the back which was highly reactive to touch. T. appeared to tighten automatically out of fear and trigger a general flexor contraction pattern—a process that commonly occurs if a person is guarding an area.
Often a traumatic injury first induces a general shock that triggers an automatic freeze and fear reaction. Therefore, an intervention needed to be developed that did not trigger vigilance or fear and thereby allowed the muscle to relax. If pain is experienced or increased, it is another negative reinforcement for generalizing guarding and bracing and tightening the muscles. This guarding decreases mobility – a common reaction that may occur when health professionals in the process of assessment increase the client’s discomfort. T.’s vigilance was also “telegraphed” to the therapist by her ice-cold hands and very shallow chest breathing. Therefore, it was important to increase her comfort level and to not induce any further pain. We hypothesized that only if she felt safe it would be possible for her muscle tension to decrease and thereby increase her mobility.
Underlying concept: The very cold hands and shallow breathing probably indicated excessive vigilance and arousal—a possible indicator of a catabolic state that could limit regeneration. The chronic cold hands most likely implied that she was very sensitive to other people’s emotions and continuously searches/scans the environment for threats. In addition, she indicated that she liked to do/perform her best which induced more anxiety and fear of judgement.
Single Channel Surface Electromyographic (SEMG)Assessment
The triode electrode with sensor was placed over the left pectoralis muscle area as shown in Figure 1. The equipment was a MyoTrac™ produced by Thought Technology Ltd. which is a small portable SEMG with the preamplifiers at the triode sensor to eliminate electrode lead and movement artefacts (Peper & Gibney, 2006). Such a device is an inexpensive option for people who may use biofeedback for demonstrating and teaching awareness and control over muscle tension from a single electrode location.
Figure 1. Location of the Triode electrode placement on the left pectoralis muscle area of another participant.
The MyoTrac was placed on a table within view, so that the therapist and the subject could simultaneously see the visual feedback signal and observe what was going on as well as demonstrate expected changes. The feedback was used for T. as a tool to see if she could reduce her SEMG activity. It was also used by the therapist to guide his interventions: To keep the SEMG activity low and to stop any intervention that would increase the SEMG activity as this would prevent bracing as a possible reaction to, or anticipation of, pain.
1. Assessment of Muscle Reactivity. After the electrode was attached on her pectoralis muscle and with her arm resting on her lap, she was asked to roll her left shoulder slightly more forward, hold the tension for the count of 10 and then let go and relax. Even with feedback, the muscle activity stayed high and did not relax and return to a lower level of activity as shown in Figure 2. This lack of return to baseline is often a diagnostic indicator of muscle irritability or injury (Sella, 1998; Sella, 2006). If the muscle does not relax immediately after contraction, movement or exercise should not be prescribed, since it may aggravate the injury. Instead, the person first needs to learn how to relax and then learn how to relax between activation and tensing of the muscle. The general observation of T. was that at the initiation of any movement (active or passive) muscle tension increased and did not return to baseline for more than two minutes.
Figure 2. Simulation of the effect on the pectoralis sEMG (this is a recording from another subject who showed a similar response pattern that was visually observed from T. with the Myotrac). After the muscle is contracted it takes a long time to return to baseline level
2. Exploration. Self-exploration with feedback was encouraged. T. was instructed to let go of muscle tension in her left shoulder girdle. In addition the therapist tried to induce her letting go by gently and passively rocking her left arm. The increased SEMG activity and the protective bracing in her shoulder showed that she couldn’t reduce the muscle tension. Each time her arm was moved, however slightly, she helped with the movement and kept control. In addition, T. was asked to reduce the muscle tension using the biofeedback signal; again she was not able to reduce her muscle tension with feedback.
3. Passive Stretch and Movements. The next step was to passively stretch the pectoralis muscle by holding the shoulder between both hands and very gently externally rotate the shoulder — a process derived from the Alexander technique (Barlow, 1991). Each time the instructor attempted to rotate her shoulder, the SEMG increased and T. reported an increased fear of pain. T.’s SEMG response most likely consisted of the following components:
- Movement induced pain
- Increased splinting and guarding
- Increased arousal/vigilance to perform well
These three assessment and self-regulation procedures were unsuccessful in reducing muscle tension or increasing shoulder movement. This suggested that another therapeutic intervention would need to be developed to allow the left pectoralis area to relax. The SEMG could be used as an indicator whether the intervention was successful as indicated by a reduction in SEMG activity. Finally, the inability to relax after tightening (bracing and splinting) probably aggravated her discomfort.
Multiple levels of injury: The obvious injury and discomfort was due to her left chest wall being hit by the ski pole. She then guarded the area by bracing the muscles to protect it which limited movement. The guarding tightened the muscles and limited blood circulation and lymphatic flow which increased local ischemia, irritation and pain. This led to a self-perpetuating cycle: Pain triggers guarding and guarding increases pain and impedes self-healing.
As the SEMG and passive stretching assessment were performed, the therapist concurrently discussed the pain process. Namely, from this perspective, there were at least two types of pains:
- Pain caused by the physiological injury
- Pain as the result of guarding
The pain from the guarding is similar to having exercised for a long time after not having exercised. The next day you feel sore. However, if you feel sore, you know that it was due to the exercise therefore it is defined as a good pain. In T.’s case, the pain indicated that something was wrong and did not heal and therefore she would need to protect it. We discussed this process as a way to use cognitive reframing to change her attitude toward guarding and pain.
Rationale: The intention was to interrupt her negative image of pain that acted as a post hypnotic suggestion. The objective was to change her image and thoughts from “pain indicates the muscle is damaged” to “pain indicates the muscle has worked too hard and long and needs time to regenerate.”
Treatment interventions
The initial intervention focused upon shifting shallow thoracic breathing to diaphragmatic breathing. Generally, when people breathe rapidly and predominantly in their chest, they usually tighten their neck and shoulder muscles during inhalation. One of the reasons T. breathed in her chest was that her clothing–very tight jeans–constricted her waist (MacHose & Peper, 1991; Peper et al., 2015). This breathing pattern probably contributed to sub-clinical hyperventilation and was part of a fear or flexor response pattern. When she loosened the upper buttons of her jeans and allowed her stomach to expand her pectoralis muscle relaxed as she breathed as shown in Figure 3. As she began to breathe in this pattern, each time she exhaled her pectoralis muscle tension decreased.
Figure 3. Illustration of the effect of loosening tight waist constriction (eliminating designer’s jean syndrome) on blood flow and pectoralis sEMG. Abdominal breathing became possible and finger temerature increased (this recording is from another subject whose physiological responses were similar to that was observed with the Myotrac from T.)
Following the demonstration that breathing significantly lowered her chest muscle tension, the discussion focussed on the importance of effortless diaphragmatic breathing for health and reduction of vigilance. Being awkward and uncomfortable at loosening her pants, she struggled with allowing her abdomen to expand and her pants to be looser because she thought that she looked much more attractive in tight clothing. Yet, she agreed that her boy friend would love her regardless whether she wore loose or tight clothing. To encourage an acceptance for wearing looser clothing and thereby permit diaphragmatic breathing during the day, an informal discussion focused on “designer jeans syndrome” (chest breathing induced by tight clothing) with humorous examples such as discussing the name of the room that is located on top of the stairs in the Victorian houses in San Francisco. It is called the fainting room–in the 19th century women who wore corsets and had to climb the stairs would have to breathe rapidly and then would faint when they reached the top of the stairs (Peper, 1990).
Rationale: Rapid shallow chest breathing can induce a catabolic state that inhibits healing while diaphragmatic breathing may induce an anabolic state that promotes regeneration. Moreover, effortless diaphragmatic breathing would increase respiratory sinus arhythmia (RSA)–heart rate variability linked to breathing– and thereby facilitate sympathetic-parasympathetic balance that would promote self-healing.
The discussion included the use of the YES set which meant asking a person questions in such a way that she/he answers the question with YES. When a person answers YES at least three times in a row rapport is often facilitated (Erikson, 1983, pp. 237-238). Questions were framed in such a way that the client would answer with YES. For example, if the therapist thought the person did not do their homework, a yes question could be framed as, “It must have been difficult to find time to do the homework this week?” In T.’s case, the therapist said, “I see, you would rather wear tight clothing than allow your shoulder to heal.” She answered, “Yes.” This was the expected answer, however, the question was framed in an intuitive guess on the therapist’s part. Nevertheless, the strategy would have been successful either way because if she had answered “No,” it would have broken the “Yes: set, but she would then be committed to change her clothing.
Throughout this discussion, the therapist placed his left hand on her abdomen over her belly button and overtly and covertly guided her breathing movement. As she exhaled, he pressed gently on her abdomen; as she inhaled he drew his hand away–as if her abdomen was like a balloon that inflated during inhalation and deflated during exhalation. To enhance learning diaphragmatic breathing and slower exhalation, the therapist covertly breathed at the same rhythm and gently exhaled as she exhaled while allowing the breathing movement to be mainly in his abdomen. In this process, learning occurred without demand for performance and she could imitate the breathing process that was covertly modelled by the therapist.
The Change
The central observation was that each time she tried to relax or do something, she would slight brace which increased her pectoralis SEMG activity. The chronic tension from guarding probably induced localized ischemia, inhibited lymphatic flow and drainage, and reduced blood circulation which would increase tissue irritation. Whenever the therapist began to move her arm, she would anticipate and try to help with the movement. Overall she was vigilant (also indicated by her very cold hands) and wanted to perform very well (a possible need for approval). Her muscle bracing and helping with movement was reframed as a combined activity that consisted of guarding to prevent further injury and as a compliment that she would like to perform well.
Labelling her activity as a “compliment” was part of a continuing YES set approach. The therapist was deliberately framing whatever happened as adaptive behaviour, with positive intent. Further, if one tries and does something with too much effort while being vigilant, the arousal would probably induce hand cooling. If the activity can be performed with passive attention, then increased blood flow and warmth may occur. The therapeutic challenge was how to reduce vigilance, perfectionism and guarding so that the muscles that were guarding the traumatized area would relax.
Therapeutic concept: If a direct approach does not work, an indirect approach needs to be employed. Through an indirect approach, the person experiences a change without trying to focus on doing or achieving it. Underlying this approach is the guideline: If something does not work, try it once more and then if it does not work, do something completely different. This is analogous to sexual arousal: If you demand from a male to have an erection: The more performance you demand the less likely will there be success. On the other hand, if you remove the demand for performance and allow the person to become interested and thereby feel an erotic experience an erection may occur without effort.
The shift to an indirect intervention was done through active somatic visualization. T. was encouraged to visualize and remember a positive image or memory from her past. She chose a memory of a time when she was in Paris with her grandmother. While T. visualized being with her grandmother, the therapist asked another older women participant to help and hold T’s right hand in a grandmother-like way as if she was her grandmother. The “grandmother” then moved T.’s hand in a playful way as if dancing with T.’s right arm. Through this kinesthetic experience, T. became more and more absorbed in her memory experience. At the same time, T´s left hand was being held and gently rocked by the therapist. During this gentle rocking, the SEMG activity decreased completely in her left pectoralis area. The therapist used the SEMG feedback to guide him in the gentle rocking motion of T.’s left arm and very slowly increased the range of her arm and shoulder motion. Gentle movement was done only as long as the SEMG activity did not increase. It allowed the muscle to stay relaxed and facilitated the experience of trust. The following is T. report two days later of what happened.
“Initially it was very difficult for me to let go of control because I found this idea somewhat strange and I was puzzled. I expected the therapist to intervene and I felt frightened. The therapist’s soft and gentle touch and his very soft voice in this kind of meditation helped me to let go of control and I was surprised about my own courage to give myself into the process without knowing what would happen next.”
Rationale: Every corresponding thought and emotion has an associated body response and every body response has an associated mental/emotional response (Green & Green, 1977; Green, 1999). Therefore, an image and experience of a happy and safe past memory will allow the body to evoke the same state and vigilance can be abated. The intensity of the experience is increased when multi-sensory cues are included such as actual handholding. The more senses are involved, the more the experience can become real. In addition, the tactile sensation of feeling the grandmother’s hand diverted her attention away from her shoulder into her hand and thereby reduced her active efforts of trying to relax the shoulder and pectoralis area. Doing something she did not expect to happen also helped her loose control – an implicit confusion approach.
SEMG feedback was used as the guide for controlling the movement. The therapist gently increased the range of the movements in abduction and external rotation directions while continuously rocking her arm until her injured arm was able to move unrestricted in full range of motion. The arm and shoulder relaxation and continuous subtle movement without evoking any SEMG activation facilitated blood flow and lymphatic drainage which probably reduced congestion. After a few minutes, the therapist gently dropped her arm on her lap. After her arm was resting on her lap, she reported that it felt very heavy and relaxed and that she didn’t feel any pain. However, she initially didn’t really realize that her mobility had increased dramatically.
Rationale: When previous movements that had been associated with pain are linked to an experience of pleasure, the movement is often easier. The conditioned muscle bracing patterns associated with anticipation of pain and/or concern for improvement/results are reduced.
Process to deepen and generalize the relaxation and breathing. She was asked to imagine breathing the air down and through her arms and legs–a strategy that she could then do at home with her boyfriend. We wanted to involve another person because it is often difficult to do homework practices without striving and concern for results and focussing on the area of discomfort. Her response to asking if her boyfriend would help was an automatic “naturally” (the continuation of the YES set). With her agreement, we role played how her boyfriend was to encourage diaphragmatic breathing. He was to gently stroke down her legs as she exhaled. She could then just focus on the sensations and allow the air to flow down her legs. Then, while she continued to breathe effortlessly, he would gently rock and move her arm.
To be sure that she knew how to give the instructions, the therapist role played her boyfriend and then asked her to rock his arm so that she would know how to teach her boy friend how to move her arm. The therapist sat on her left side, and, as she now held his right arm and gently rocked it with her left arm, the therapist gently moved backwards. This meant that she externally rotated her left arm and shoulder more and more. He moved in such a way that in the process of rocking his arm, she moved her “previously injured shoulder” in all directions (up, down, forward and backwards) and was unaware that she could move her arm and shoulder as she did not experience any discomfort. Afterwards, we shared our observations and she was asked to move her arm and shoulder. She moved it without any restrictions or discomfort.
Rationale: By focusing outside herself and not being concerned about herself, she did not think of herself or of trying to move her arm and shoulder. Hence, she did not evoke the anticipatory guarding and thus significantly increased her flexibility.
Process of acceptance. Often after an injury, we are frustrated with our bodies. This frustration may interfere with healing. Therefore, the session concluded by asking her to be appreciative of her shoulder and arm. She was asked to think of all the positive things her shoulder, chest and arm have done for her in the past instead of the many limitations and pains caused by the injury. Instead of being angry at her shoulder that it had not healed or restricted her movement, we suggested that she should appreciate her shoulder and pectoralis area for all it had done without her awareness such as: How the shoulder moved her arm during love-making, how without complaining her shoulder moved during walking, writing, skiing, eating, etc., and how many times in the past she had abused her shoulder without giving it proper respect and appreciation. This process reframes the way one symbolically relates to the injured area. Every thought of discomfort or negative judgement becomes the trigger and is transformed into breathing lower and slower and evokes an appreciation of the positive nice things her shoulder has done for her in the past.
Rationale: When injured we often evoke negative mental and emotional images which become post- hypnotic suggestions. Those negative thoughts, images and emotions interfere with healing while positive thoughts, images and emotions tend to promote healing. A possible energetic process that occurs when injured is that we withdraw awareness/ consciousness from the injured area which reduces blood and lymph circulation. Caring and positive feelings about an area tends to increase blood flow and warmth (a heart-warming experience) and promotes healing.
RESULTS
She left the initial session without any pain and with total range of motion. At the two week follow-up she reported continued pain relief and complete range of motion. T.s reflection of the experience was:
“I really was not aware that I could move my arm freely like before the accident, I was just feeling a kind of trance and was happy to not feel any pain and to feel much more upright than before. Then I watched the faces of the two other therapists who sat there with big eyes and a grin on their face and then become aware of my own arms position which was rotated backwards and up, a movement that was impossible to do before. I remember this evening that I left with this feeling of trance and that I often tried to go back to my collapsed posture but this was not possible anymore and I felt very tall and straight. Now two weeks later I still feel like that and know that I had an amazing experience which I will store in my brain!
My father who is an orthopedic surgeon tested me and found out, that I had hurt my rib. He said that I have a contusion and it will go away in a few weeks. Before this experience, I would say that he was not open to Biofeedback. However he was so captivated by my experiences that he spontaneously promised me to pay for my own biofeedback equipment and to support me with my educational program and even offered me a job in his practice to do this work!”
Psychophysiological Follow-up: 3 Weeks Later
The physiological assessment included monitoring thoracic and abdominal breathing patterns, blood volume pulse, heart rate and SEMG from her left pectoralis muscle while she was asked to roll her left shoulder forward (adducted and internally rotated) for the count of 10 and then relax. The physiological recording showed that she breathed more diaphragmatically and that her pectoralis muscle relaxed and returned directly to baseline after rotation as shown in Fig. 4.
Figure 4. Physiological profile during the rolling left shoulder forward (tense) and relaxing at thethree week follow-up. Note that the pectoralis sEMG activity returned rapidly to baseline after contracting and her breathing pattern is abdomninal and slower.
Summary
This case example demonstrates the usefulness of a simple one-channel SEMG biofeedback device to guide the interventions during assessment and treatment. It suggests that the therapist and client can use the SEMG activity as an indicator of guarding–a visual representation of the subjective experience of fear, pain and range of mobility–that can be evoked during assessment and therapeutic interventions. The anticipation of increased pain commonly occurs during diagnosis and treatment and often becomes an obstacle for healing because increased pain may increase anticipation of pain and trigger even more bracing. To avoid triggering this vicious circle of guarding/fear, the feedback signal allows the therapist and the client to explore strategies that reduce muscle activity by indirect interventions.
By using an indirect approach that the client may not expect, the interventions shift the focus of attention and striving and may allow increased freedom and relaxation. The biofeedback signal may guide the therapeutic process to reduce the patterns of fear, panic, and bracing that are commonly associated with injury and illnesses. Once this excessive sympathetic activity is reduced, the actual pathophysiology may become obvious (in most cases is much less then before) and the healing process may be accelerated. This case description may offer an approach in diagnosis and treatment for many therapists and open a door for a gentle, painless and yet successful way of treatment and encourage therapists to be creative and use both experience/technique and intuition.

Are food companies responsible for the epidemic in diabetes, cancer, dementia and chronic disease and do their products need to be regulated like tobacco? Is it time for a class action suit?

Why are one third of young Americans becoming obese and at risk for diabetes?
Why are heart disease, cancer, and dementias occurring earlier and earlier? Is it genetics, environment, foods, or lifestyle?
Is it individual responsibility or the result of the quest for profits by agribusiness and the food industry?
Like the tobacco industry that sells products regulated because of their public health dangers, is it time for a class action suit against the processed food industry? The argument relates not only to the regulation of toxic or hazardous food ingredients (e.g., carcinogenic or obesogenic chemicals) but also to the regulation of consumer vulnerabilities. Addressing vulnerabilities to tobacco products include regulations such as how cigarette companies may not advertise their products for sale within a certain distance from school grounds.
Is it time to regulate nationally the installation of vending machines on school grounds selling sugar-sweetened beverages? Students have sensitivity to the enticing nature of advertised, and/or conveniently available consumable products such as ‘fast foods’ that are highly processed (e.g., packaged, preserved and practically imperishable). Whereas ‘processed foods’ have some nutritive value, and may technically pass as ‘nutritious’ food, the quality of processed ‘nutrients’ can be called into question. For the purpose of this blog other important questions to raise relate to ingredients which, alone or in combination, may contribute to the onset of or, the acceleration of a variety of chronic health outcomes related to various kinds of cancers, cardiovascular diseases, and diabetes.
It may be an over statement to suggest that processed food companies are directly responsible for the epidemic in diabetes, cancer, dementia and chronic disease and need to be regulated like tobacco. On the other hand, processed food companies should become much more regulated than they are now.
More than 80 years ago, smoking was identified as a significant factor contributing to lung cancer, heart disease and many other disorders. In 1964 the Surgeon Generals’ report officially linked smoking to deaths of cancer and heart disease (United States Public Health Service, 1964). Another 34 years pased before California prohibited smoking in restaurants in 1998 and, eventually inside all public buildings. The harms of smoking tobacco products were well known, yet many years passed with countless deaths and suffering which could have been prevented before regulation of tobacco products took place. Reviewing historical data there is about a 20 year delay (e.g., a whole generation) before death rates decrease in relation to when regulations became effective and smoking rates decreased, as shown in figure 1.
Figure 1. The relationship between smoking and lung cancer. Reproduced by permission from Roser, M. (2021). Smoking: How large of a global problem is it? And how can we make progress against it? Our world in data.
During those interim years before government actions limited smoking more effectively, tobacco companies hid data regarding the harmful effects of smoking. Arguably, the ‘Big Tobacco’ industry paid researchers to publish data which could confuse readers about tobacco product harm. There is evidence of some published articles suggesting that the harm of cigarette smoking was a hoax– all for the sake of boosting corporate profits (Bero, 2005).
Now we are experiencing a similar problem with the processed food industry. It has been suggested that alongside smoking and vaping, opioid use, a sedentary ‘couch potato’ lifestyle, and lack of exercise, ultra-processed food (UPF) that we eat severely affects our health.
Ultra-processed foods, which for many constitutes a majority of calories ranging from 55% to over 80% of the food they eat, contain chemical additives that trick the tastebuds, mouth and eventually our brain to desire those processed foods and eat more of them (Srour et al., 2022).
What are ultra-processed foods? Any foods that your great grandmother would not recognize as food. This includes all soft drinks, highly processed chips, additives, food coloring, stabilizers, processed proteins, etc. Even oils such as palm oil, canola oil, or soybean are ultra processed since they heated, highly processed with phosphoric acid to remove gums and waxes, neutralized with chemicals, bleached, and deodorized with high pressure steam (van Tulleken, 2023).
The data is clear! Since the 1970s obesity and inflammatory disease have exploded after ultra-processed foods became the constituents of the modern diet as shown in figure 2.
Figure 2. A timeline from 1850 to 2000 reflects the increase in use of refined sugar and high fructose corn syrup (HFCS) to the U.S. diet, together with the increase in U.S. obesity rate. The data for sugar, dairy and HFCS consumption per capita are from USDA Economic Research Service (Johnson et al., 2009) and reflects historical estimates before 1967 (Guyenet et al., 2017). The obesity data (% of U.S. adult population) are from the Robert Wood Johnson Foundation’s Trust for America’s Health. (stateofobesity.org). Total U.S. television advertising data are from the World Advertising Research Center (www.warc.com). The vertical measure (y–axis) for kilograms per year (kg/yr) on the left covers all data except advertising expenditures, which uses the vertical measure for advertising on the right. Reproduced by permission from Bentley et al, 2018.
This graph clearly shows a close association between the years that high fructose corn syrups (HFCS) were introduced into the American diet and an increase in TV advertising with corresponding increase in obesity. HFCS is an ultra-processed food and is a surrogate marker for all other ultra-processed foods. The best interpretation is that ultra-processed foods, which often contain HFCS, are a causal factor of the increase in obesity, and diabetes and in turn are risk factors for heart disease, cancers and dementias.
Ultra-processed foods are novel from an evolutionary perspective.
The human digestive system has only recently encountered sources of calories which are filled with so many unnatural chemicals, textures and flavors. Ultra-processed foods have been engineered, developed and product tested to increase the likelihood they are wanted by consumers and thereby increase sales and profits for the producers. These foods contain the ‘right amount’ processed materials to evoke the taste, flavor and feel of desired foods that ‘trick’ the consumer it eat them because they activate evolutionary preference for survival. Thus, these ultra-processed foods have become an ‘evolutionary trap’ where it is almost impossible not to eat them. We eat the food because it capitalized on our evolutionary preferences even though doing so is ultimately harmful for our health (for a detailed discussion on evolutionary traps, see Peper, Harvey & Faass, 2020).
An example is a young child wanting the candy while waiting with her parents at the supermarket checkout line. The advertised images of sweet foods trigger the cue to eat. Remember, breast milk is sweet and most foods in nature that are sweet in taste, provide calories for growth and survival and are not harmful. Calories are essential of growth. Thus, we have no intrinsic limit on eating sweets unlike foods that taste bitter.
As parents, we wish that our children (and even adults) have self-control and no desire to eat the candy or snacks that is displayed at eye level (eye candy) especially while waiting at the cashier. When reflecting about food advertising and the promotion of foods that are formulated to take advantage of ‘evolutionary traps’, who is responsible? Is it the child, who does not yet have the wisdom and self-control or, is it the food industry that ultra-processes the foods and adds ingredients into foods which can be harmful and then displays them to trigger an evolutionary preference for food that have been highly processed?
Every country that has adapted the USA diet of ultra-processed foods has experienced similar trends in increasing obesity, diabetes, cardiovascular disease, etc. The USA diet is replacing traditional diets as illustrated by the availability of Coca-Cola. It is sold in over 200 countries and territories (Coca-Cola, 2023).
An increase in ultra-processed foods by 10 percent was associated with a 25 percent increase in the risk of dementia and a 14 per cent increase in the risk of Alzheimers’s (Li et al., 2022). More importantly, people who eat the highest proportion of their diet in ultra-processed foods had a 22%-62% increased risk of death compared to the people who ate the lowest proportion of processed foods (van Tulleken, 2023). In the USA, counties with the highest food swamp scores (the availability of fast food outlets in a county) had a 77% increased odds of high obesity-related cancer mortality (Bevel et al., 2023). The increase risk has also been observed for cardiovascular disease, coronary heart disease, cerebrovascular disease and all cause mortality as is shown in figure 3 (Srour et al., 2019; Rico-Campà et al., 2019).

The harmful effects of UPF holds up even when correcting for the amount of sugars, carbohydrates or fats in the diet and controlling for socio economic variables.
The logic that underlies this perspective is based upon the writing by Nassim Taleb (2012) in his book, Antifragile: Things That Gain from Disorder (Incerto). He provides an evolutionary perspective and offers broad and simple rules of health as well as recommendations for reducing UPF risk factors:
- Assume that anything that was not part of our evolutionary past is probably harmful.
- Remove the unnatural/unfamiliar (e.g. smoking/ e-cigarettes, added sugars, textured proteins, gums, stabilizers (guar gum, sodium alginate), emulsifiers (mono-and di-glycerides), modified starches, dextrose, palm stearin, and fats, colors and artificial flavoring or other ultra-processed food additives).
What can we do?
The solutions are simple and stated by Michael Pollan in his 2007 New York Times article, “Eat food. Not too much. Mostly Plants.” Eat foods that your great grandmother would recognize as foods (Pollan, 2009). Do not eat any of the processed foods that fill a majority of a supermarket’s space.
- Buy only whole organic natural foods and prepare them yourself.
- Request that food companies only buy and sell non-processed foods.
- Demand government action to tax ultra-processed food and limit access to these foods. In reality, it is almost impossible to expect people to choose healthy, organic foods when they are more expensive and not easily available in the American ‘food swamps and deserts’ (the presence of many fast food outlets or the absence of stores that have fresh produce and non-processed foods). We do have a choice. We can spend more money now for organic, health promoting foods or, pay much more later to treat illness related to UPF.
- It is time to take our cues from the tobacco wars that led to regulating tobacco products. We may even need to start class action suits against producers and merchants of UPF for causing increased illness and premature morbidity.
