Support the healing process: Be a gardener not a mechanic
Posted: January 9, 2022 Filed under: Uncategorized 4 Comments
Six years ago, I had a bilateral hernia repair, the surgeon was highly recommended and recognized as an expert in his field. Although the surgery was a mechanical success, the failure of the post-operative care resulted in severe urinary retention, multiple emergency room visits, and ongoing urinary difficulties. Six weeks after the surgery, I was still lugging a Foley catheter with a leg collection bag that drained my bladder. The surgeon had stated I could be back doing physical activities with a week (Peper, 2019). From my perspective the surgeon was a mechanic and not a gardener. The moment the mechanical structure was fixed in surgery, he had completed his work even if post-surgical complications arose.
Being a mechanic in medicine is an important role. The concept of being a mechanics is not limited to surgery, it can be applied to any treatment strategy when the practitioner focuses narrowly only on the presenting issue. A broken bone > align and put on a cast; hip pain due to the breakdown of cartilage > hip replacement surgery; depression > prescribe antidepressant medication; diabetes > prescribe medications to reduce blood sugar; hypertension > -prescribe anti-hypertensive medication; pain > prescribe opioids, etc. In many cases, healing is much more than mechanical interventions, it often includes post-operative care, exploring factors that may have contributed to disease onset, and retraining such as ongoing physical therapy for hip replacement surgery or teaching stress management, exercise, diet and lifestyle changes for people with diabetes.
Much of healing, especially for the treatment of chronic conditions, needs much more than a mechanical intervention. For example, type 2 diabetes, depression, or hypertension are triggered and maintained to a large extent by socio-economics inequalities and stressful lifestyles. Treatment needs to focus on healing and reduce the factors that created or now maintains the illness and support those factors that enhance healing. This is similar to the role of a gardener. Once planted, a successful gardener needs to be aware of, and support, all the factors that facilitate the plants growth (enough sunlight at the right time, appropriate watering and fertilizer, soil conditions, etc.).
These concepts are discussed in the superb article by Gavin Francis, MD and seminal book by Wayne Jonas, MD that describes how medicine needs to change and incorporate an holistic perspective to support and nurture the healing process.

Resolving a chronic headache with posture feedback and breathing
Posted: January 4, 2022 Filed under: behavior, Breathing/respiration, computer, digital devices, ergonomics, health, laptops, Neck and shoulder discomfort, Pain/discomfort, posture, relaxation, self-healing, stress management, Uncategorized | Tags: Desktop feedback app, headache, migraine 37 Comments| Adapted from Peper, E., Covell, A., & Matzembacker, N. (2021). How a chronic headache condition became resolved with one session of breathing and posture coaching. NeuroRegulation, 8(4), 194–197. https://doi.org/10.15540/nr.8.4.194 |

This blog describes the process by which a 32 year old woman student’s chronic headaches that she had since age eighteen was resolved in a single coaching session. The student suffered two or three headache per week a week which initially began when she was eighteen after using digital devices and encouraged her to slouch as she looked down. Although she describes herself as healthy, she reported having high level of anxiety and occasional depression. She self-medicated with 2 to 10 Excedrin tablets a week. It is possible that the chronic headaches could partially be triggered by caffeine withdrawal which get resolved by taking more Excedrins (Greben et al., 1980) since Excedrin contains 65 mg of caffeine as well as 250 mg of Acetaminophen which can be harmful to liver function (Bauer et al., 2021).
The behavioral coaching intervention
During the first day in class, the student approached the instructor and she shared that she had a severe headache. During their conversation, the instructor noticed that she was breathing in her chest without abdominal movement, her shoulders were held tight, her posture slightly slouched and her hands were cold. As she was unaware of her body responses, the instructor offered to guide her through some practices that may be useful to reduce her headache. The same strategies could also be useful for the other students in the class; since, headaches, anxiety, zoom fatigue, neck and shoulder tension, abdominal discomfort, and vision problems are common and have increased as people spent more time in front of screens (Charles et al., 2021; Ahmed et al., 2021; Bauer, 2021; Kuehn, 2021; Peper et al., 2021 ).
These symptoms may occur because of bad posture, neck and shoulder tension, shallow chest breathing, stress and social isolation (Elizagaray-Garcia et al., 2020; Schulman, 2002). When people become aware of their dysfunctional somatic patterns and change their posture, breathing pattern, internal language and implement stress management techniques, they often report a reduction in symptoms such as irritable bowel syndrome, acid reflux, neck and shoulder tension, or anxiety (Peper et al, 2017a; Peper et al, 2016a). Sometimes, a single coaching session can be sufficient to improve health.
Working hypothesis: The headaches were most likely tension headaches and not migraines and may be the result of chronic neck and shoulder tension which was maintained during chest breathing and the slouched head forward body posture. If she could change her posture, relax her neck and shoulders, and breathe diaphragmatically so that the lower abdomen widen during inhalation, most likely her shoulder and neck tension would decrease. Therefore, by changing posture from a slouched to upright position combined with slower diaphragmatic breathing, the muscle tension would be reduced and the headaches would decrease.
Breathing and posture changes
She was encouraged to sit upright so that the abdomen had space to expand (Peper et al., 2020). In addition, she needed to loosen the clothing around her waist to provide room for her abdomen to expand during inhalation instead of her chest lifting (MacHose & Peper, 1991). Allowing abdominal expansion can be challenging for many paticipants since they are self-conscious about their body image, as well holding their stomach in as an unconscious learned response to avoid pain after having had abdominal surgery, or as an automatic protective response to threat (Peper et al., 2015). The upright position also allowed her to sit tall and erect in which the back of head reaches upward towards the ceiling while relaxing and feeling gravity pulling her shoulders downward and at the same time relaxing her hips and legs.
With guided verbal and tactile coaching, she learned to master slower diaphragmatic breathing in which she gently and slowly exhaled by making a sound of pssssssst (exhaling through pursed lips) which tends to activate the transverse and oblique abdominal muscles and slightly tighten the pelvic floor muscles so that her lower abdomen would slightly constrict at the end of the exhalation (Peper et al., 2016). Then, by allowing the lower abdomen and pelvic floor relax so that the abdomen could expand in 360 degrees, inhalation occurred.
While practicing the slower breathing in this relaxed upright position, she was instructed to sense/imagine feeling a flow of down and through her arms and out her hands as she exhaled (as if the air could flow through straws down her arms). After a few minutes, she felt her headache decrease and noticed that her hands had warmed. After this short coaching intervention, she went back to her seat in class and continued to practice the relaxed effortless breathing while sitting upright and allowing her shoulders to melt downward.
The use of muscle feedback to demonstrate residual covert muscle tension
During class session, she volunteered to have her trapezius muscle monitored with electromyography (EMG). The EMG indicated that her muscles were slightly tense even though she reported feeling relaxed. With a few minutes of EMG biofeedback exploration, she discovered that she could relax her shoulder muscles by feeling them being heavy and melting.
Implementing home practice with a posture app
As part of the class homework, she was assigned a self-study for two weeks with the posture feedback app, Dario Desktop. The app uses the computer/laptop camera to monitor posture and provides visual feedback in a small window on the computer screen and/or an auditory signal each time she slouches as shown in Figure 1.

Figure 1. Posture feedback to signal to participant that the person is slouching.
To observe the effect of the posture breathing training, she monitored her symptoms for three days without feedback and then installed the posture feedback application on her laptop to provide feedback whenever she slouched. The posture feedback reminded her to practice better posture during the day while working on her computer and also do a few stretches or shift to standing when using the computer for an extended period of time. Each time the feedback signal indicated she slouched, she would sit up and change her posture, breathe lower and slower and relax her shoulders.
She also monitored what factors triggered the slouching. In additionally, she added daily reminders to her phone to remind her of her posture and to stretch and stand after each hour of studying. After two weeks she recorded her symptoms for three days for the post assessment without posture feedback.
Results
The chronic headache condition which had been present for fourteen years disappeared and she has not used any medication since the first day of class. She reported after two weeks that her shoulder and back discomfort/pain, depression, anxiety and lack of motivation decreased as shown in Figure 2. At the fourteen week follow up, she continues to have no headaches and has not used any medication.

Figure 2. Changes in symptoms after implementing posture feedback for two weeks.
She used the desktop posture app every time she opened her laptop at home as often as 3-5 times per day (roughly 2-6 hours).In addition, when she felt beginning of discomfort or thought she should take medication, she would adjust her posture and breathe. While using the app, she identified numerous factors that were associated with slouching as shown in Figure 3.

Figure 3. Behaviors associated with slouching.
Discussion
The decrease in depression, anxiety and increase in motivation may be the direct result of posture change; since, a slouched position tends to increase hopeless, helpless and powerless thoughts while the upright position tends to increase subjective felt energy and easier access to empowering and positive thoughts (Peper et al., 2017b; Veenstra et al., 2017; Wilson & Peper, 2004; Tsai et al., 2016). Most likely, a major factor that contributed to the elimination of her headaches was that she implemented changes in her behavior. One major factor was using posture feedback tool at home to remind her to sit tall and relax her shoulders while practicing slower diaphragmatic breathing. As she noted, “Although it was distracting to be reminded all the time about my posture, it did decrease my neck pain. With the pain reduction, I was able to sit at the computer longer and felt more motivated.”
The combination of slower lower abdominal breathing with the upright posture reversed her protective/defensive body position (tightening the muscle in the lower abdomen and pelvic floor and pressing the knees together while curling the shoulder forward for protection). The upright posture creates a position of empowerment and trust by which the lower abdomen could expand which supported health and regeneration. In addition, the upright posture allowed easier access to positive thoughts and reduced recall of hopeless, powerless, defeated memories. It is also possible that caffeine withdrawal was a co-factor in evoking headaches (Küçer, 2010). By eliminating the medication containing caffeine, she also eliminated the triggering of the caffeine withdrawal headaches.
This case example suggests that health care providers first rule out any pathology and then teach behavioral self-healing strategies that the clients can implement instead of immediately prescribing medications. These interventions could include slower and lower diaphragmatic breathing, upright posture feedback, muscle biofeedback training, hear rate variability training, stress management, cognitive behavior therapy and facilitating health promoting lifestyles modifications such as regular sleep, exercise and healthier diet. When students implement these behavioral changes as part of a five week self-healing program, many report significant decreases in symptoms such as headaches, anxiety, neck and shoulder pain, and gastrointestinal distress (Peper et al., 2016a).
Watch April Covell describe her experience with the self-healing approach to eliminate her chronic headaches.

Healing from paralysis-Music (toning) to activate health
Posted: November 22, 2021 Filed under: behavior, Breathing/respiration, emotions, healing, health, mindfulness, stress management, Uncategorized | Tags: chakra, chanting, music therapy, paralysis, quadriplegia, singing, Toning 8 CommentsMadhu Anziani and Erik Peper

In April 2009, Madhu Anziani, just one month prior to graduation from San Francisco State University with a degree in Jazz/World music performance, fell two stories and broke C5 and C7 vertebras. He became a quadriplegic (tretraplegia) and could not breathe, talk, move his arms and legs and was incontinent. He also could not remember anything about the accident because of retrograde amnesia. Even though he was paralyzed and the medical staff suggested that he focussed on how to live well as a quadriplegic, he transcended his paralysis and the prognosis and is now a well-known vocal looping arts and ceremonial song leader/composer.
His recovery against all odds provides hope that growth and healing is possible when the mind and spirit focus on possibilities and not on limitations. Alongside physical thereapy he utilized energy healing and toning/sound vibrations to recover mobility. Toning, the vocalization of an elonggated monotonous vowel sound susteained for a number of minutes tends to vibrate specific areas in the body where the chakras are located (Crowe & Scovel, 1996; Goldman, 2017). Toning compared to mindfulness meditation reduces intrusive thoughts and mind wandering. It also increases body vibration sensations and heart rate variability much more than mindfulness practice (Peper et al, 2019). The body vibrations induced by toning and music could be one of the mechanisms by which recovery can occur at an accelerated rate as it allows the person’s passive awareness and sustained attention to feel the paralyzed body and yet be relaxed in the present without judgement.
Watch Madhu’s inspirational presentation as part of the Holistic Health Lecture Series by the Institute for Holistic Health Studies, San Francisco State University. In this presentation, he describes the process of recovery and guides the viewer through toning practices to evoke quieting of mind, bliss within the heart, and a healing state of being.
For an additional discussion and guided practice in toning, see the blog, Toning quiets the mind and increases HRV more quickly than mindfulness practice.
Madu Anziani is a sound healer who endured being a tetraplegic (paralysis affecting all four
limbs) and used sound and energy healing to recover mobility. He is a SFSU graduate and most
well-known as a vocal looping artist and ceremonial song leader/composer.

Digital fatigue and what to do
Posted: July 22, 2021 Filed under: Uncategorized 6 CommentsErik Peper, PhD and Monica Almendras
The article was adapted from the recent book, How Technology is Hijacking our Lives, Strategies for Coping and Pragmatic Ergonomics, and was originally published on the Big Q https://www.thebigq.org/2021/08/02/why-do-we-have-zoom-fatigue-and-what-can-we-do-about-it/
Why is it that after studying, working, entertaining and socializing at the computer screen or looking at texts, Instagram, Facebook, Tiktok or responding to notifications on the cellphone, we often feel exhausted (zoom fatigue) and experience neck, back and shoulders discomfort, or eye irritation? Time disappears as we surf the web and go down the rabbit hole by clicking on one and then another link or responding to social media. As time flies, we tend to be unaware that our muscles tighten, our breathing become shallow and quicker, our blinking rates decreases and our posture slouches forward as we bring our nose close to the screen to see the text more clearly.
Become aware what happens when you do the following experiential practices
Observe what happens when you mouse
Sit comfortable in an erect posture as if you are in front of your computer and hold a small object that you can use to simulate mousing to the side of the keyboard. With an actual mouse (or the sham mouse), pretend to draw the letters of your name and your street address backward, right to left. Be sure each letter is very small (less than half an inch in height). After drawing each letter, right click. Draw the letters and numbers as quickly as possible without making any mistakes for fifteen seconds. Stop and observe what happened in your body.
If you are like almost all participants you tightened your neck and shoulders, stiffened your trunk, held your breath and most did not blink. All this occurred without awareness. Over time, this covert tension can contribute to discomfort, soreness, pain, or eventual injury.
Observe the effect of low static muscle tension
You probably felt discomfort in the muscles of your hip. As you lifted your knee up, you most likely also held your breath and tightened your neck and back. Holding your muscles in a static position for more than a few minutes creates discomfort. Yet, when you walk you use the same muscles and usually do not experience discomfort. The main difference is that during walking you sequentially tighten and relax these muscles. Each time the muscle relaxes, blood flow is restored to remove the waste produces of metabolism and supply nutrients and oxygen to the muscle tissue. For more information, see the blog, Reactivate your second heart.
From the evolutionary perspective, people typically shifted between sitting, walking, and moving in varied ways during specified forms of labor which tends to tighten and relax different muscles. Therefore, incorporate dynamic movement’ during the day: Stand up, wiggle and move several times an hour. To avoid sitting disease, install a break reminder program such as StretchBreak on your computer or other digital devices. When people implement taking breaks, they report having much more energy at the end of the day. As one participant stated: “There is now life after five”. What he meant was that at the end of the day when he got home, he still had energy to other things.
Observe how breathing and opening eyes affect tearing
Inhale with a gasp as you open your eyes. Close your eyes, then exhale and inhale with a gasp as if you are surprised and at the same time open your eyes then look as if you are quickly responding to a notification. Repeat one or two time and be sure to open your eyes wide the moment you gasp as you inhale
Exhale and slowly open your eyes. Close your eyes, then inhale by allowing your abdomen to expand and begin exhaling and slowly open your eyes. Repeat one or two more times as you open your eyes midway through the exhalation, while your shoulders relax. What did you experience?
Most likely when you opened your eyes while exhaling you found that your eyes felt more relaxed with more tearing moisture in the eyes, while gasping and looking the eyes felt tense and more dry. In most cases when we focus without awareness intensely at the screen we create eye tension. Thus, practice blinking by resting and closing your eyes then gently open your eyes as you exhale and then looking at the far distance relax the muscles of the eyes. For detailed instructions see the blog, Are you encouraging your child to get into accidents or even blind when growing up?
We are usually unaware that our bodies respond automatically and that these patterns occur covertly and totally without awareness while working at the computer or responding to texts. We only notice when symptoms of discomfort occur. Fortunately, it is possible to monitor the degree of muscle tension with an electromyograph (EMG). The unaware muscle tension can be identified by physiological recording of the electrical activity produced when they contract. With biofeedback and coaching people can learn to become aware of the covert tension and as shown in Figure 1.

Figure 1. A representative recording of a person working at the computer. Note the following: 1) forearm and shoulder (deltoid/trapezius) muscle tension increased as the person rests her hands on the keyboard without typing; 2) respiration rate increased during typing and mousing; 3) shoulder muscle tension increased during typing and mousing; and, 4) there were no rest periods in the shoulder muscles as long as the fingers are either resting, typing, or mousing. Reproduced by permission from Peper & Harvey, 2008.
Even though the physiological recording showed increase tension when the hands were resting on the keyboard, the person reported being relaxed. The person was also not aware that her neck and shoulder muscles stayed contracted without any momentary rest and recovery periods nor that her breathing rate and heart rate significantly increased. The covert muscle activity and shallow breathing will also interact with the person’s stress level, as well as ergonomic equipment use and the posture throughout the day. Similarly, we tend to be unaware that we slouch which would increase neck and back tension as well as, affect breathing as illustrated in figure 2.

Maintaining and optimizing health at the computer means re-envisioning our relationship with technology—reclaiming health, happiness, and sanity in a plugged-in world. We have the ability to control everything from our mobile phones without needing to get up from our seat. Work, social life and online learning all involve the mobile phone or some type of smart devices. A convenient little device that is supposed to simplify our lives has actually trapped us into a vicious cycle of relying on it for every single thing we must do. We spend most of our day being exposed to digital displays on our smartphones, computers, gaming consoles, and other digital devices, immersing ourselves in the content we are viewing. From work related emails or tasks, to spending our free time looking at the screen for texting, playing games, and updating social media sites on a play-by-play of what we are eating, wearing, and doing. A typical thing to do on our devices is to click on one hyperlink after the other and create a vicious cycle in which we are trapped for hours until we realize we need to move. As we do this, we are unaware how much time has frittered away without actually doing anything productive and then, we realize we have wasted another day.
Transform digital fatique into digital health (adapted from https://news.sfsu.edu/news-story/professors-share-tips-healthy-tech-usage-during-pandemic)
Get up and move
About every 20 minutes, stand up and move your body. Consider doing a quick dance to a favorite song or taking a walk around the block. “It will feel silly, yet actively moving is one of the quickest energizers,” Stretching and moving will also relax those muscles that you tense constantly when working at a desk. Think you’ll forget to take a break? Install the free Stretch Break app as a great tool to remind you. For more background information, see the blog, Sitting disease is the new health hazard.
Blink and look far off
Our blinking rate significantly decreases while looking at a screen, which contributes to eye strain. A good way to address this is by blinking every time you click on a hyperlink or after you finish typing a paragraph. To relax the eyes, look at the far distance. “Looking out into the distance disrupts constant near-focus muscle tension in the eyes.” For more suggestions, see the blog, Resolve Eyestrain and Screen Fatigue.
Avoid phones and screens right before bed
Many people use their phones before bed, which can make it more difficult to sleep. Take a break from your phone half an hour or more before bedtime. Electronic screens emit blue light, which can send a signal to your brain that it’s daytime. This suppresses your body’s production of the hormone melatonin, which helps your body know when it’s time to sleep. In addition, keeping up with social media and watching digital media tends to be thought-provoking or anxiety-inducing may stimulate the mind and promote wakefulness. For more suggestions, see the blog, Are LED screens harming you?
Optimize ergonomics
Make sure your computer setup is ergonomically friendly. Your desktop keyboard should be positioned so that your forearms are a few inches above your waist. The top of your screen should be around eyebrow level, which should naturally cause your eyes to look slightly downward at the screen.
Unfortunately, using a laptop or a phone causes people to look down in an unhealthy way that can make them slouch and induce neck or back pain. The solution is to get an external keyboard along with a laptop stand. Getting an external monitor can also help. For more detailed suggestions, see the blogs, Cartoon ergonomics for working at the computer and laptop and Reduce TechStress at Home.
Sit erect and stop slouching
As we work at the computer, we unknowingly tend to slouch which increases the risk of neck and shoulder discomfort and evoking thoughts and feelings. Take control of your slouching with a posture feedback device and app such as UpRight Go [3] that reminds you when you slouch as shown in Figure 3. Each time you the device signals you that you slouch, sit up straight, move, breathe, and think of a positive thought. For more suggestions, see the blog, “Don’t slouch!” Improve health with posture feedback.

Practice slow diaphragmatic breathing
Breathe deeply and slowly to restore a natural rhythm. As we work, we tend to breathe more shallowly, which increases anxiety and our heart rate. To counteract this, take three deep breaths for five seconds, then exhale very slowly for six seconds. For more instructions on slower diaphragmatic breathing, see the blog, Healing irritable bowel syndrome with diaphragmatic breathing.
Give undivided attention and be present
Phones have become so ingrained in our lives that we use them constantly throughout the day. Harvey stresses that people should make a conscious effort to limit phone usage, especially when socializing. When we respond to a phone notification during a Zoom hangout with friends or while talking to our family members, people may feel dismissed. This often increases a sense of social isolation, so give people your total attention when interacting with them. For more suggestions, see the blog, Configure your brain to learn and avoid Zoom fatigue.

Dysfunctional breathing, eating highly processed foods, and lack of movement contribute to development of illnesses such as cancer, diabetes, cardiovascular disease and many chronic diseases. They also contributes to immune dysregulation that increases vulnerability to infectious diseases, allergies and autoimmune diseases. If you wonder what breathing patterns optimize health, what foods have the appropriate phytonutrients to support your immune system, or what the evidence is that exercise reduces illness and promotes longevity, look at the following resources.

Adapted in part from: TechStress-How Technology is Hijacking our Lives, Strategies for Coping and Pragmatic Ergonomics by Erik Peper, Richard Harvey and Nancy Faass
As a young child I laid on the couch and I read one book after the other. Hours would pass as I was drawn into the stories. By the age of 12 I was so nearsighted that I had to wear glasses. When my son started to learn to read, I asked him to look away at the far distance after reading a page. Even today at age 34, he continues this habit of looking away for a moment at the distance after reading or writing a page. He is a voracious reader and a novelist of speculative fiction. His vision is perfect. –Erik Peper
How come people in preliterate, hunting and gatherer, and agricultural societies tend to have better vision and very low rates of nearsightedness (Cordain et al, 2003)? The same appear true for people today who spent much of their childhood outdoors as compared to those who predominantly stay indoors. On the other hand, how come 85% of teenagers in Singapore are myopic (neasighted) and how come in the United States myopia rate have increased for children from 25% in the 1970s to 42% in 2000s (Bressler, 2020; Min, 2019)?

Why should you worry that your child may become nearsighted since it is easy correct with contacts or glasses? Sadly, in numerous cases, children with compromised vision and who have difficulty reading the blackboard may be labeled disruptive or having learning disability. The vision problems can only be corrected if the parents are aware of the vision problem (see https://www.covd.org/page/symptoms for symptoms that may be related to vision problems). In addition, glasses may be stigmatizing and children may not want to wear glasses because of vanity or the fear of being bullied.
The recent epidemic of near sightedness is paritally a result of disrespecting our evolutionary survival patterns that allowed us to survive and thrive. Throughout human history, people continuously alternated by looking nearby and at the distance. When looking up close, the extraocular muscles contract to converge the eyes and the ciliary muscles around the lens contract to increase the curvature of the lens so that the scene is in focus on the retina — this muscle tension creates near visual stress.
The shift from alternating between far and near vision to predominantly near vision and immobility

Figure 2. The traditional culture of Hdzabe men in Tanzania returning from a hunt. Notice how upright they walk and look at the far distance as compared to young people today who slouch and look predominantly at nearby screens.
Experience the effect of near visual stress.
Bring your arm in front of you and point your thumb up. Look at your thumb on the stretched out arm. Keep focusing on the thumb and slow bring the thumb four inches from your nose. Keep focusing on the thumb for a half minute. Drop the arm to the side, and look outside at the far distance.
What did you experience? Almost everyone reports feeling tension in the eyes and a sense of pressure inside around and behind their eyes. When looking at the distance, the tension slowly dissipates. For some the tension is released immediately while for others it may take many minutes before the tension disappears especially if one is older. Many adults experience that after working at the computer, their distant vision is more fuzzy and that it takes a while to return to normal clarity.
When the eyes focus at the distance, the ciliary muscles around lens relaxes so that the lens can flatten and the extra ocular muscles relax so that the eyes can diverge and objects in the distance are in focus. Healthy vision is the alternation between near and far focus– an automatic process by which the muscles of the eyes tightening and relax/regenerate.
Use develops structure and structure limits use
If we predominantly look at nearby surfaces, we increase near visual stress and the risk of developing myopia. As children grow, the use of their eyes will change the shape of the eyeball so that the muscles will have to contract less to keep the visual object into focus. If the eyes predominantly look at near objects, books, cellphones, tablets, toys, and walls in a room where there is little opportunity to look at the far distance, the eye ball will elongate and the child will more likely become near sighted. Over the last thirty year and escalated during COVID’s reside-in-place policies, children spent more and more time indoors while looking at screens and nearby walls in their rooms. Predominantly focusing on nearby objects starts even earlier as parents provide screens to baby and toddlers to distract and entertain them. The constant near vision remodels the shape of eye and the child will likely develop near sightedness.
Health risks of sightedness and focusing predominantly upon nearby objects
- Increased risk of get into an accident as we have reduced peripheral vision. In earlier times if you were walking in jungle, you would not survive without being aware of your peripheral vision. Any small visual change could indicate the possible presence food or predator, friend or foe. Now we focus predominantly centrally and are less aware of our periphery. Observe how your peripheral awareness decreases when you bring your nose to the screen to see more clearly. When outside and focusing close up the risk of accidents (tripping, being hit by cars, bumping into people and objects) significantly increases as shown in figure 3 and illustrated in the video clip.
Pedestrian accidents (head forward with loss of peripheral vision)

Figure 3. Injuries caused by cell phone use per year since the introduction of the smartphone (graphic from Peper, Harvey and Faass,2020; data source: Povolatskly et al., 2020).
- Myopia increases the risk of eye disorder. The risk for glaucoma, one the leading causes of blindness, is doubled (Susanna, De Moraes, Cioffi, & Ritch, R. 2015). The excessive tension around the eyes and ciliary muscles around the lens can interfere with the outflow of the excess fluids of the aqueous humour through the schlemm canal and may compromise the production of the aqueous humour fluid. These canals are complex vascular structures that maintains fluid pressure balance within the anterior segment of the eye. When the normal outflow is hindered it would contribute to elevated intraocular pressure and create high tension glaucoma (Andrés-Guerrero, García-Feijoo, & Konstas, 2017). Myopia also increases the risk for retinal detachment and tears, macular degeneration and cataract. (Williams & Hammond, 2019).
By learning to relax the muscles around the lens, eye and face and sensing a feeling of soft eyes, the restriction around the schlemm canals is reduced and the fluids can drain out easier and is one possible approach to reverse glaucoma (Dada et al., 2018; Peper, Pelletier & Tandy, 1979).
- Increase in neck and upper back compression when the person cranes their head forward or looks down while reading books/articles, looking at a cellphone or a laptop screen, This often results in an increase of back, neck and shoulder pain as well as headaches (Harvey, Peper, Booiman, Heredia Cedillo, & Villagomez, 2018; Hansraj, 2014).
- Decrease in subjective energy and increase in helpless, hopeless, powerless and defeated thoughts when the person habitually looks down in a slouched position (Peper, Booiman, Lin, & Harvey, 2016; Peper, Lin, Harvey, & Perez, 2017).
WHAT CAN YOU DO?
The solutions are remarkable simple. Respect your evolutionary background and allow your eyes to spontaneously alternate between looking at near and far objects while being upright (Schneider, 2016; Peper, 2021; Peper, Harvey & Faass, 2020).
For yourself and your child
- Let children play outside so that they automatically look far and near.
- When teaching children to read have them look at the distance at the end of every paragraph or page to relax the eyes.
- Limit screen time and alternate with outdoor activities
- Every 15 to 20 minutes take a vision break when reading or watching screens. Get up, wiggle around, move your neck and shoulders, and look out the window at the far distance.
- When looking at digital screens, look away every few minutes. As you look away, close your eyes for a moment and as you are exhaling gently open your eyes.
- Practice palming and relaxing the eyes. For detailed guidance and instruction see the YouTube video by Meir Schneider.
Create healthy eye programs in schools and work
- Arrange 30 minute lesson plans and in between each lesson plan take a vision and movement breaks. Have children get up from their desks and move around. If possible have them look out the window or go outside and describe the furthest object they can see such as the shape of clouds, roof line or details of the top of trees.
- Teach young children as they are learning reading and math to look away at the distance after reading a paragraph or finishing a math problem.
- Teach palming for children.
- During recess have students play games that integrate coordination with vision such as ball games.
- Episodically, have students close their eyes, breathe diaphragmatically and then as they exhale slowly open their eyes and look for a moment at the world with sleepy/dreamy eyes.
- Whenever using screen use every opportunity to look away at the distance and for a moment close your eyes and relax your neck and shoulders.

Why did the CDC mishandle the COVID-19 pandemic response?
Posted: May 10, 2021 Filed under: education, health, Uncategorized | Tags: CDC, COVID-19 1 CommentThe CDC (Centers for Disease Control and Prevention) located in Atlanta, George, with a stellar international reputation responded too late and incompetently to the COVID-19 pandemic in the United States. Although many people blame the Trump administration for the failed response, a significant factor was the risk adverse and politicized CDC.. To understand what actually happened, listen to the superb New York Times podcast with Michael Lewis and read his just published book, The Premonition: A Pandemic Story. The interview and his book should be the first requirement for anyone interested in Public Health careers, government service and public policy.

Nutrition to support the Stress Response

Let food be thy medicine and medicine be thy food
-Hippocrates, the Greek physician and father of medicine.
What should I eat? More greens, more Vitamin D, more fish, no meats, no grains, or should I become a vegetarian, go on a ketogenic diet, or evolutionary diet? There are so many options. What are the best choices?
The foods we eat provide the building blocks and energy source for our body. If you eat high quality foods, the body has the opportunity to create and maintain a healthy strong structure; on the other hand, if you eat low quality foods, it is more challenging to create and maintain a healthy body. The analogy is building a house. If the materials are high quality, the structure well engineered and well built, the house has the opportunity to age well. On the other hand, if the house is built out of inferior materials and poorly engineered, it is easily damaged by wind, rain or even earthquakes.
Although we are bombarded with recommendations for healthy eating, many of the recommendations are not based upon science but shaped by the lobbying and advertisement efforts of agribusiness. For example, the scientific recommendations to reduce sugar in our diet were not implements in the government guidelines. This demonstrates the power of lobbying which places profits over health.
Officials at the Department of Agriculture and the Department of Health and Human Services rejected explicit caps on sugar and alcohol consumption. Although “the preponderance of evidence supports limiting intakes of added sugars and alcoholic beverages to promote health and prevent disease.” (Rabin, 2020).
To make sense out of the multitude of nutritional recommendations, watch the superb presentation by Dr. Marisa Soski, ND, Nutrition to Support Stress Response.* She discusses how and what we eat has direct impact on how our bodies manage our reactions to stress.

Configure your brain to learn and avoid Zoom fatigue [1]
Posted: March 31, 2021 Filed under: behavior, computer, digital devices, education, Exercise/movement, health, laptops, screen fatigue, Uncategorized, zoom fatigue | Tags: attention, education, learning 3 CommentsAdapted from: Peper, E., Wilson, V., Martin, M., Rosegard, E., & Harvey, R. (2021). Avoid Zoom fatigue, be present and learn. NeuroRegulation, 8(1), 47–56. https://doi.org/10.15540/nr.8.1.47

After a while, it all seems the same. Sitting and looking at the screen while working, taking classes, entertaining, streaming videos and socializing. The longer I sit and watch screens, the more I tend to feel drained and passive, and the more challenging it is to be present, productive and pay attention.
Overnight, the pandemic transformed college teaching from in-person to online education. Zoom[2] became the preferred academic teaching and learning platform for synchronous education. Students and faculty now sat and looked at the screen for hours. While looking at the screen, the viewers were often distracted by events in their environment, notifications from smartphones, social media and email, which promoted multitasking (Solis, 2019). The digital distractions causing people to respond to twice as many devices with half of our attention—a process labeled ‘semi-tasking’- meaning getting twice as much done half as well.
For many students synchronous online learning was more challenging, especially after teaching was shifted to a Zoom environment without adapting the course materials to optimize online learning. During polling of 325 undergraduate university students at a metropolitan university who were all taking synchronous online Zoom classes, the vast majority reported that learning was somewhat to extremely difficult, with only the minority of students (approximately 6%) preferring online learning as shown in Figure 1.

Figure 1. Survey of 325 Undergraduates comparing Zoom online learning compared to the previous in person classes. Approximately 94% had moderate to considerable difficulty with on line learning.
The increased self-report on difficulty experienced in synchronous Zoom online learning may also affect academic achievement. At the same time, many people have reported an increase in physical, behavioral and psycho-emotional problems (e.g. backache, headache, stomachache, eye-strain, sore neck and shoulder pain, over or under eating, over or under sleeping, over or under exercising, ruminative thoughts related to categories of anxiety/fear, boredom/numbness, depression/sadness, anger/hostility, etc) (Fosslien & Duffy, 2020; Lee, 2020; Intolo, 2019; Leeb et al, 2020; McGinty et al, 2020; Peper & Harvey, 2018; Peper, Harvey and Faas, 2020).
This post explores factors that contribute to zoom fatigue and offers practical suggestions to optimize learning during synchronous Zoom online education. The concepts are derived from our teaching athletes to sustain peak mental and physical performance, with the implication that the same concepts can help students towards sustaining on-topic attention during online learning (Wilson & Peper, 2011). In sports, the coach can help guide the athlete; however, the athlete needs to be present and motivated. Faculty have a responsibility to support, encourage, and engage students while students have the responsibility to configure themselves into an optimum learning state.
Part 1: Factors that contribute to Zoom fatigue
Differences in communication between live and computer communication
Until the 20th century, almost all communication included non-verbal expressions. The speaker used verbal and nonverbal expressions while the respondent would immediately show a reaction to the speaker. There was a continuous dynamic verbal and nonverbal exchange. The listener would respond to the speaker. If they agreed they nodded their head. If they disagreed or were intimidated they would provide alternative body movements (e.g., shake their head) or facial expressions (look away or frown). During normal conversations, both the speaker’s facial expression and body language are noticed and responded to, which are in turn, can be used as feedback by the other person. In large group sessions with many participants, the visual feedback is reduced and facial responses are difficult to distinguish especially the gallery view.
In a Zoom environment, both the sender and receiver are watching the computer screen without awareness that nonverbal cues are essential for the purpose of understanding not only what is being said but also for the implied meaning and its importance. These non-verbal cues are usually processed without awareness in live person-to-person exchange. While sending and receiving are usually simultaneous, there can exist a disconnect between the attached meanings of the encoded information and that of the decoded information due to the inconsistent existence of important nonverbal components. In a Zoom environment, the end-result could mean multiple images of receivers providing the sender with little or no non-verbal cues with which to interpret the meaning they have attached to your message. The person may appear to look at you; however, you do not know whether they are attending to you, have a neurological disorder and cannot respond, are reading their emails, watching YouTube videos, or texting on their phone. Additionally, the nonverbal cues they are sending may not be related to your message but to their reaction to other media, people or distractions not seen by the presenter.
This mode of communication is different from communication patterns that evolved through natural selection and allowed the human species to thrive and survive. For the first time in human history we learn, teach, work, socialize, and entertain in front of the same screen. In many cases, communication in the era of smartphones has been reduced to texting, writing digital responses or reacting to media content on any screen. Over the past few decades, it is possible for people to communicate through more disembodied, off-topic and external modes of interaction. So many types of learning activities vie for our attention and can occur without leaving our chairs, thus, it may be difficult to stay on-topic online Zoom classes (Keller, Davidesco, & Tanner, 2020).
Normal communication typically involves whole body movements (face, head, arms and hands) which tends to energize or sometimes distract the speaker or listener (Kendon, 2004). When communicating with friends-we often move our bodies dynamically and responsively during the discussion. With synchronous large online lectures, students tend to be passive and just sit and watch.[3] This state of sitting and just watching the screen is similar to watching video entertainment where we sit for a long time and are covertly conditioned not to act.
Unknowingly, we have trained ourselves not to initiate action since the screen does not provide feedback to our responses- a process so different from talking and responding spontaneously in groups of participants.
When communication is safe, people interact, respond and chime in. In large groups, just like large lectures, Zoom tends to inhibit this process because it delays social feedback since most people mute their microphone to avoid extraneous noise. This is usually the rule for large groups although for small groups, people often unmute themselves. The physical act of unmuting is an additional barrier to spontaneous verbal responses. This shift of attention induces a delay before responding. From a communication perspective, a delay before responding reduces the spontaneity and is may be interpreted more negatively by the listener (Roberts, Margutti, & Takano, 2011).
Facial Expressions and Auditory Processing
Facial expressions are a critical part of non- verbal feedback and signals to the other person that they are being listened to and provide cues that the interaction is safe. We unknowingly react to facial expressions–processed unconsciously through neuroception (Porges, 2017)–to indicate whether the person is signaling safety or danger. Usually when the person is facially responsive and shows expression, it signals safety and allows communication and intimacy to be developed. If the person shows no facial expressions (a still/flat face), we unconsciously interpret this as a signal of danger (Porges, 2017). The importance of responsive feedback is illustrated in the study by Tronick et al (1975) where mothers were instructed not to respond with facial and body cues to their infant. The babies rapidly became highly disturbed when the mother stayed nonresponsive as dramatically illustrated in the YouTube video, Still Face Experiment: Dr. Edward Tronick (Tronick, 2007). In adults lack of verbal and nonverbal feedback during social evaluations is extremely stressful (Gruenewald, Kemeny, Aziz, & Fahey, 2004; Birkett, 2011).
The absence of social facial and body feedback often makes teaching and learning more challenging. Namely, are the receivers–the invisible, (only their picture or name is shown), partially visible (facial features are indistinct due to backlighting) or ghosting (those whose picture and name are shown but are physically absent from the session)–understanding the information the way the sender intended?
Unlike traditional classroom settings where one has the benefit of seeing/sensing nonverbal cues, the Zoom gallery view often, the speaker may not know what how the audience is responding and this contributes to Zoom fatigue. In addition, the communication bond is often reduced when the speaker does not look at audience and the listener does not respond to the speaker with facial expressions. Zoom fatigue can also be reduced when online teaching tools are used appropriately by involving active feedback responses through polls, chat, etc. as well as asking specific participants to speak and give feedback.
What is unique to the synchronous online environment is that the speakers and participants view themselves. This is the first time in human history that people are seeing themselves while speaking[4]. For some people, seeing themselves may increase anxiety and negative self-judgement- a process that is even more prevalent in teens. Some are self-conscious and some have social anxiety and do not want their face to be shown (Degges-White, 2020). In the past, most of us had no idea how we looked when others or ourselves are communicating—it is totally novel experience to see yourself while talking and communicating.
Reduced physical activity and increased near vision stress.
Before sheltering in place, I would walk from my house to the BART station, take the train to Daly City station and then walk to the university. At the university, I would climb stairs to go to my office, meet with other faculty and walk to the classroom. At the end of the day, I would walk back to the Bart station and eventually walk home. Without any thinking or trying to do any exercise, I usually would do 12,000 steps and about 25 stairs. Now, I am lucky if I do 3000 unless will myself to do more exercise. –Erik Peper
The move to a Zoom environment and sheltering in place meant that we sit more and more which tends to increase mortality, decrease subjective energy and contributes to an attitude of passive engagement, more as an observer than as a participant (Stamtakis et al, 2019; Patel et al, 2018; Oswald et. al., 2020; Yalçin, Özkurt, Özmaden & Yagmur, 2020). While sitting, we also tend to slouch as we look at the screen that may be a covert factor in the increasing rates of depression and anxiety.
This slouching position tends to decrease access to positive memories and allow easier access to negative memories (Peper et al, 2017) as well as interfere with academic performance. Peper et al (2018) found that students have more difficulty performing mental math in the slouched as compared to upright sitting position. To reduce the impact of sitting, Peper & Lin (2012) found that when student perform some physical activities (e.g., skipping in place) for just a minute they report a significantly increase subjective energy and attention levels.
When looking at the screen our eyes only focus on the screen, which is different from in-person communication where you look at the person and then look at behind or to the side of the person. Only looking at the screen means that to focus on the screen the muscles of the eyes tighten so that the eyes can converge and the ciliary muscles around the lens contract so that the lens curvature is increased which results in near visual stress. This continuous looking at a near object is different from normal eye function in which we alternately focus on nearby objects and then look far away which allows the muscles of the eyes to relax.
Student Issues
Numerous students reported that it was much easier to be distracted and multitask, check Instagram, facebook, TikTok, or respond to emails and texts than during face-to-face classroom sessions as illustrated by two students’ comments.
“Now that we are forced to stay at home, it’s hard to find time by myself, for myself, time to study, and or time to get away. It’s easy to get distracted and go a bit stir-crazy.”
“I find that online learning is more difficult for me because it’s harder for me to stay concentrated all day just looking at the screen.”
Students often reported that they had more difficulty remembering the materials presented during synchronous presentations. Most likely, the passivity while watching Zoom presentation affected the encoding and consolidation of new material into retrievable long term memory. The presented material was rapidly forgotten when the next screen image or advertisement appeared and competed with the course instructor for the student’s attention. We hypothesize that the many hours of watching TV and streaming videos have conditioned people to sit and take in information passively, while discouraging them to respond or initiate action (Mander, 1978; Mărchidan, 2019). Learning requires engagement, which means a shifting from passively watching and listening to being an active, participant shareholder in synchronous online classes. However, in most cases, students have not received information/education or training on HOW TO be a more active/engaged participant in a synchronous Zoom class.
Instructor Issues
Instructors also have many of the same issues when presenting classes online. They engage in multiple simultaneous roles: presenter, director, and producer. While teaching, they need to engage students, monitor the chat for feedback and look at the screen for facial responses. At the same time, they may face similar technical issues as those experienced by students such as internet connectivity, limited bandwidth, and mastering the technical features of synchronous online learning technology. At times, instructors feel that students expect each presentation to be as captivating as a TED talk. Thus, teaching has shifted from education to edutainment.
Part 2: Practical suggestions to optimize learning
To optimize learning in the synchronous online environment, teachers have the responsibility to reconfigure their teaching so that it incorporates active student involvement and students have the responsibility to be present and engaged. The following practices may facilitate learning:
Be present to learn
Mastering media presence is becoming even more important for everyone. The skill implemented in attending an online learning class will also be useful for professional development. Although the pandemic shifted personal interviews to online interviews, most likely, synchronous and asynchronous video interviews are part of the first automatic screening level to assess candidates for a job (Rubinstein, 2020).
Be visible for the other person looking at you to create a positive impression
Adjust your camera and lights so that your face is visible and you are looking at the person to whom you are talking. Your screen presence is representing you. Does the camera show you engaged or distracted lying on bed? Be aware that you and your background together create an impression. The concept that looking directly at the audience– looking directly at the camera–is not new. Everyone working in media (newscasters, politicians, actors) have been trained to make their faces visible and expressive. This means arranging your webcam at eye level right in front of you and speaking to the camera as if it is the person. Avoid looking down at the person on the screen since the viewer would see you looking look down and away. Be sure your face is illuminated and there are no bright light sources behind you (Purdy, 2020). We recommend that in small group, participants unmute their microphones so that people can respond spontaneously to each other unless there is excessive background noise.
Be a responsive and interactive listener to configure your brain to be engaged
Shift from being a passive absorber to an active participant even if your camera is off or the speaker cannot see you. Imagine being physically with the speaker and activate yourself by increasing your face and body animation as you are attending a synchronous online class. Thus, when you watch a presentation, act as if you are in a personal conversation with the presenter or the material. This means that if you agree, nod your head; if you disagree, shake your head (do this naturally without making it a work task). Do this for the whole session. Our research has shown that when college students purposely implement animated facial and body responses during Zoom classes, they report a significant increase in energy level, attention and involvement as compared to just attending normally in class (Peper & Yang, in press). See Figure 2.

Figure 2. Change in subjective energy, attention and involvement when the students significantly increase their facial and body animation by 123 % as compared to their normal non-expressive class behavior (Peper & Yang, 2021).
“I never realized how my expressions affected my attention. Class was much more fun”
-22 year old woman student.
“I can see how paying attention and participation play a large role in learning material. After trying to give positive facial and body feedback I felt more focused and I was taking better notes and felt I was understanding the material a bit better.”-28 year old medical student
Configure your body to attend and perform
Sit upright and adapt a position of empowerment. When we sit upright and expanded it is easier to have positive thoughts and detach from negative hopeless thoughts (Peper, Lin, Harvey, & Perez, 2017; Peper, Harvey, Mason, & Lin, 2018). Students also performed better in mental math when they sat upright as compared to collapsed. When students are provided ongoing feedback when they begin to slouch by an app that uses the computer camera to monitor slouching, they reported a significant decrease in neck and back symptoms (Chetwynd et al, 2020). As one of many students reported:
“Before when I didn’t use the app, I had a lots of shoulder and neck pain. Now when I use it, the pain went way down as I kept changing posture to the feedback signal. I had more energy and I was more alert. I did notice that when I would get the alert to sit up straight.”
Optimize concentration and learning
In the online environment, the structure more likely depends upon the person unlike the externally created structure of going to work or to class. Thus, purposely creating a time structure and scheduled time-periods to perform different tasks as time management skills are associated with improved school and work performance (Macan et al., 1990). Create an environment to promote concentration and reduce distractions.
- Stay on task and reduce interruption and practice refocusing on task. On the average we now check our phones 96 times a day—that is once every 10 minutes and an increase of 20% as compared to two years ago (Asurion Research, 2019). Those who do media multitasking such as texting while doing a task perform significantly worse on memory tasks than those who are not multitasking (Madore et al., 2020). Multitasking is negatively correlated with school performance (Giunchiglia et al, 2018). When working or attending a class or meeting, turn off all notifications (e.g., email, texts and social media). Then block out specific times when you work on Zoom and when you respond to email, phone or social media (Newport, 2016). Let people know that you will look at the notifications and respond in a predetermined time so that you will not be interrupted while working or studying. If you work where there are other people, arrange your workstation so that there are fewer distractions such as sitting with your back to other people. When students chose to implement a behavior change to monitor cellphone and media use and reduce the addictive behavior during a five-week self-healing project, many report a significant improvement of health and performance. One student observed that when she reduced her cellphone use her stress level equally decreased as shown in Fig 3.

Figure 3. Example of a student changing cellphone use and corresponding decrease in subjective stress level.
During this class project, many students observed that the continuous responding to notifications and social media affect their health and productivity. As one student reported,
The discovery of the time I wasted giving into distractions was increasing my anxiety, increasing my depression and making me feel completely inadequate. In the five-week period, I cut my cell phone usage by over half, from 32.5 hours to exactly 15 hours and used some of the time to do an early morning run in the park. Rediscovering this time makes me feel like my possibilities are endless. I can go to work full time, take online night courses reaching towards my goal of a higher degree, plus complete all my homework, take care of the house and chores, cook all my meals, and add reading a book for fun! –22 year old College Student
- Approached learning with a question. When you begin to study the material or attend a class, ask yourself questions that you would like to be answered. If possible, put your questions to the instructor. When you have a purpose, it is easier to stay emotionally present and remember the material (Osman, & Hannafin, 1994).
- Take written notes while attending a Zoom meeting or class. When participants take hand written notes versus on the computer they tend to integrate and remember the material much more than just watching passively (Mueller & Oppenheimer, 2014). Active note taking leads to focused attention and fewer distractions from social media content (Flanigan & Titsworth, 2020).
- Review materials. At the end of the class, meet with your fellow students on ZOOM or social media and review the class materials. As you discuss the materials, add comments to your notes and if possible, do a hierarchical outline to more easily remember the relationships among the ideas.
- Change your internal language. What we overtly or covertly say and believe is what we may become. When one says, “I am stupid”, “I can’t do math,” or “It is too difficult to learn,” one may become powerless which increases stress and inhibits cognitive function. Instead, change the internal language so that it implies that you can master the materials such as, “I need more time to study and to practice the material,” “Learning just takes time and at this moment it may take a bit longer than for someone else,” or “I need a better tutor.”
Create an environment to trigger the appropriate mental and emotional state for learning.
Learning and recall are state dependent. Without awareness, the learned content is covertly associated with environmental, emotional, social and kinesthetic cues. Thus, when you study in bed, the material is more easily accessed while lying down. When you study with music, the music becomes a retrieval cue. Without awareness, the materials are encoded with the cues of lying down or the music played in the background. When you take your exam in a different setting then you have studied, none of the covert cues are there, thus, it is more difficult to recall the material. Study and review the materials under similar conditions, as you will be tested.
To configure yourself to be ready to study, work, or socialize create different environments that are unique to each category of Zoom involvement (studying, working, socializing, entertaining). Pre COVID, we usually used different clothing for different events (work versus party) or different environments for different tasks (temple, churches, mosques, or synagogue for religious practice; bar or coffee shop to meet friends). Create a unique environment with each Zoom activity. The stimuli to be associated to the specific tasks can also include lighting, odors, sound or even drinks and food. These stimuli become the classically conditioned cues to evoke the appropriate response associated with the task just as Pavlov conditioned dogs to salivate by pairing a sound with the meat. Taking charge of the conditioning process may help many people to focus on their task as so many students use their bedroom, kitchen or living room for Zoom work which is not always conducive for learning or work.
- Wear task specific clothing just as you would have done going to work or school. When you plan to study, put on your study T-shirt. In time, the moment you put on the study T-shirt, you are cueing yourself to focus on studying. When finishing with studying, change your clothing.
- Arrange task specific backgrounds for each category of Zoom task. Place a different background such as a poster or wall hanging behind the computer screen-one for studying and another for entertainment. When finished with the specific Zoom event, take down the poster and change the background.
Optimize arousal and regenerate vision
- The longer we sit the more passive we tend to become. Teachers will benefit by interrupting the passive transfer of information by guiding students in fun short movements to increase arousal. If instructors fail to put in movement breaks, students sitting in front of screens can remind themselves to move. The challenge is that we are usually unaware of how much time has passed as we are captured by the screen. It is often helpful to use an app such as StretchBreak[5] to remind yourself to get up and move.
- Get up and move every 30 minutes. After sitting for 30 minutes stretch, wiggle and move. Do the movements with vigor or even dance, look up and reach up. When you stand up and move your legs and feet, you tighten and relax your calf muscles that pump the venous blood and lymph fluids that have been pooling in your legs back to your heart. The calf muscle is often called the second heart because in facilitates venous blood return.
- Regenerate vision. Our eyes tend to get tired and world looks blurry. Interrupt the near vision stress by allowing the eyes to relax and regenerate.
- Palming. Bring your hands to your face and cup the hands so that there is no pressure on your eyeballs. Allow the base of the hands to touch the cheeks while the fingers are interlaced and resting your forehead. Then with your eyes closed imagine seeing black. Breathe slowly and diaphragmatically while feeling the warmth of the palm soothing the eyes. Feel your shoulders, head and eyes relaxing and do this for five minutes (Schneider, 2016; Peper, 2021).
- Look at the distance. Interrupt near visual stress (convergence of the eyes and tightening of the ciliary muscle around the lens allows us to focus on the screen) by looking away at the far distance. Every so look at the clouds, top of trees or rooftops outside the window to relax the eyes.
Summary
By activating the evolutionary communication patterns that allowed us to survive and thrive and using known performance enhancement skills derived from peak performance training, we can enhance involvement and productivity. The instructor needs to stay current on methods that keep students attention. At the same time, students have a responsibility to configure themselves to optimize learning. We recommend practices 1) to be present and learn, 2) optimize concentration and learning, 3) create an environment to trigger the appropriate mental and emotional state for learning, and 4) optimize arousal and regenerate vision. By taking charge of your own teaching/learning process and configuring yourself to be present through active participation, learning is enhanced.

Clean the air with plants*
Posted: March 22, 2021 Filed under: Breathing/respiration, ergonomics, health, Uncategorized | Tags: air pollution, plants Leave a comment
Fresh clean air is essential for health while polluted air is an environmental health hazard. For more than fifty years the harm of air pollution has been documented. As the National Institute of Environmental Health Sciences (NIH NIEHS) points out, initially air pollution was primarily regarded as threat to respiratory health and contributed to an increases in asthma, emphysema, chronic obstructive pulmonary disease, and chronic bronchitis. More recently, air pollution has been identified as a significant risk factor for cardiovascular disease, diabetes mellitus, obesity, reproductive, neurological, and immune system disorders and ADHD (Keller et al., 2018; Perera et al, 2014; NIH NIEHS ).
Yet many of us are unaware that often the air we breathe indoors is even more polluted than the outside air. The indoor air is the sum of outdoor air plus the indoor air pollution produced from cooking and outgassing of the volatile organic compounds (VOCs) from the many materials (Wolkoff, 2028). Materials and equipment in home and office also shed micro dust particles and outgas a chemical brew of volatile organic compounds (e.g., formaldehyde, benzene and tricholorethylene). These VOCs come from paper, inks, furniture, carpet, paints, wall coverings, cleaning materials, floor tiles and the fumes produced from gas heaters and cooking stoves. In addition, copiers and laser printers often add microscopic dust particles and sometimes ozone. These gasses stay in the room where there is limited air circulation due to sealed buildings or closed windows. Reduced air circulation is also a significant risk factor for COVID-19; since, the virus keeps recirculating in unventilated rooms. See the superb graphic illustration by Bartzokas et al (Feb 26, 2021).in the New York Times of virus concentration in schools when the windows are opened. https://www.nytimes.com/interactive/2021/02/26/science/reopen-schools-safety-ventilation.html?smid=em-share).
Be proactive to reduce pollution and enhance your health by placing plants in your office and home. When the plants are placed in the office, they also enhances subjective perceptions of air quality, concentration, and workplace satisfaction as well as objective measures of productivity (Nieuwenhuis et al., 2014). Certain plants help remove carbon dioxide and convert it to oxygen, clear the indoor smog, and remove the volatile organic compounds. Warning: Be sure that your pets do not chew or eat the leaves of these plants because they could be poisonous (e.g., azaleas are poisonous for dogs and cats),
The following plants help remove carbon dioxide and by converting it into oxygen.
- Areca Palm. You will need four shoulder height plants per person to convert all the exhaled carbon dioxide into oxygen (Meattle, 20009; Meattle, 2018).
- Mother-in-law’s Tongue is a bedroom plant because it converts carbon dioxide into oxygen at night. You will need six to eight shoulder height plants per person (Meattle, 20009).
Watch Kamal Meattle short TED talk presentation, How to grow fresh air (for an updated longer presentation watch, https://www.youtube.com/watch?v=KXgWxRUGLwM). https://www.ted.com/talks/kamal_meattle_how_to_grow_fresh_air?language=en#t-100683
The following plants remove VOCs from the air (Wolverton, 2020).
- Azaleas, rubber plants, tulips, poinsettia, philodendron, money plant, and bamboo palms (formaldehyde)
- Areca palm (toluene)
- Lady palm (ammonia)
- Peace lily and chrysanthemum (acetone, methanol, trichlorethylene, benzene, ethylacetate)
To remove particulates, install an air purifier with a HEPA filter.
After renovation or installation of furniture or carpets, be sure to allow for air circulation by opening windows and doors. Explore some of the following strategies to clean the air:
- Turn the exhaust fan on when cooking and using the oven.
- Ventilate your work area (open a window or door, if possible).
- Move copier/laser printers to a well-ventilated space and/or place an exhaust fan near the printer.
- Turn off copier or laser printers when not in use (purchase new equipment that is energy efficient and shuts down when not in use).
Take a many walks outside in nature
If possible take a walk at lunch or ask coworkers to have a walking meeting so that you can get out in the fresh air. Being in nature and forest bathing (Shinrin-Yoku) is associated with a decrease in stress, regeneration and improvement in immune function (Park et al., 2010; Hansen et a., 2017; Lyu et al., 2019).
