TechStress: Building Healthier Computer Habits

August 28, 2023

By Erik Peper, PhD, BCB, Richard Harvey, PhD, and Nancy Faass, MSW, MPH

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). 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.

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

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.

Reflections on the increase in Autism, ADHD, anxiety and depression: Part 1-bonding, screen time, and circadian rhythm

Adapted from:  Peper, E. Reflections on the increase in Autism, ADHD, anxiety and depression: Part 1-bonding, screen time, and circadian rhythms. NeuroRegulation,10(2), 134-138. https://doi.org/10.15540/nr.10.2.134

Over the past two decades, there has been a significant increase in the prevalence of autism, Attention-Deficit/hyperactivity disorder (ADHD), anxiety, depression, and pediatric suicidal behavior. Autism rates have risen from 1 in 150 children in 2000 to 1 in 36 children in 2020 (CDC, 2023), while ADHD rates have increased from 6% in 1997 to approximately 10% in 2018 (CDC, 2022). The rates of anxiety among 18-25 year-olds have also increased from 7.97% in 2008 to 14.66% in 2018 (Goodwin et al., 2020), and depression rates for U.S. teens ages 12-17 have increased from 8% in 2007 to 13% in 2017 (Geiger & Davis, 2019; Walrave et al., 2022). Pediatric suicide attempts have also increased by 163% from 2009 to 2019 (Arakelyan et al., 2023), and during the COVID-19 pandemic, these rates have increased by more than 25% (WHO, 2022; Santomauro et al., 2021). In addition, the prevalence of these disorders has tripled for US adults during the pandemic compared to before (Ettman et al., 2020).

The rapid increase of these disorders is not solely due to improved diagnostic methods, genetic factors or the COVID-19 pandemic. The pandemic amplified pre-existing increasing trends. More likely, individuals who were at risk had their disorders triggered or amplified by harmful environmental and behavioral factors. Conceptually, Genetics loads the gun; epigenetics, behavior, and environment pull the trigger.

While behavioral strategies such as neurofeedback, Cognitive Behavior Therapy, biofeedback, meditation techniques, and pharmaceuticals can treat or ameliorate these disorders, the focus needs to be on risk reduction. In some ways, treatment can be likened to closing the barn doors after the horses have bolted.

Evolutionary perspective to reduce risk factors

Nassim Taleb (2012) in his book, Antifragile: Things That Gain from Disorder (Incerto), provides an evolutionary perspective and offers simple rules of health by reducing 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, sugar, digital media).
  • We do not need evidence of harm to claim that a drug or an unnatural procedure is dangerous. If evidence of harm does not exist, it does not mean harm does not exist.
  • Only resort to medical techniques when the health payoff is very large (to save a life), exceeds its potential harm, such as incontrovertibly needed surgery or life-saving medicine (penicillin).
  • Avoid the iatrogenics and negative side effects of prescribed medication.

Writer and scholar Taleb’s suggestions are reminiscent of the perspective described by the educator Joseph C. Pearce (1993) in his book, Evolution’s End. Pearce argued that modern lifestyles have negatively affected the secure attachment and bonding between caregivers and infants. The lack of nurturing and responsive caregiving in early childhood may lead to long-term emotional and psychological problems. He points out that we have radically adapted behaviors that differ from those that evolved over thousands of generations and that allowed us to thrive and survive. In the last 100 years, babies have often been separated from their mothers at birth or early infancy by being put in a nursery or separate room, limited or no breastfeeding with the use of formula, exposure to television for entertainment, lack of exploratory play outdoors, and the absence of constant caretakers in high-stress and unsafe environments.

As Pearce pointed out, “If you want true learning, learning that involves the higher frontal lobes – the intellectual, creative brain – then again, the emotional environment must be positive and supportive. This is because at the first sign of anxiety the brain shifts its functions from the high, prefrontal lobes to the old defenses of the reptilian brain… These young people need audio-vocal communication, nurturing, play, body movement, eye contact, sweet sounds and close heart contact on a physical level” (Mercogliano & Debus, 1999).

To optimize health, eliminate or reduce those factors that have significantly changed or were not part of our evolutionary past. The proposed recommendations are based upon Talib’s perspective that anything that was not part of our evolutionary past is probably harmful; thus, it is wise to remove the unnatural/unfamiliar and adopt the precautionary principle, which states that if evidence of harm does not exist, it does not mean harm does not exist (Kriebel et al., 2010). 

This article is the first of a three-part series. Part 1 focuses on increasing reciprocal communication between infant and caretaker, reducing screen time, and re-establishing  circadian rhythms; Part 2 focuses on reducing exposure to neurotoxins, eliminating processed foods, and supporting the human biome; and Part 3 focuses on respiration and movement.

Part 1- Increase bonding, reduce screen time, and re-establish circadian rhythms

Increase bonding between infant and caretaker

Infants develop emotional communication through reciprocal interactions with their caregivers, during which the caregiver responds to the infant’s expressions. When this does not occur, it can be highly stressful and detrimental to the infant’s development. Unfortunately, more and more babies are emotionally and socially isolated while their caregivers are focussed on, and captured by, the content on their digital screens. Moreover, infants and toddlers are entertained (babysat) by cellphones and tablets instead of dynamically interacting with their caretakers. Screens do not respond to the child’s expressions; the screen content is programmed to capture the infant’s attention through rapid scene changes. Without reciprocal interaction, babies often become stressed, as shown by the research of developmental psychologist Professor Edward Tronick, who conducted the “Still Face” experiment (Tronick & Beeghly, 2011; Weinberg et al, 2008).

The “Still Face” experiment illustrated what happens when caregivers are not responding to infants’ communication. The caregivers were asked to remain still and unresponsive to their babies, resulting in the infants becoming increasingly distressed and disengaged from their surroundings. Not only does this apply to infants but also to children, teenagers and older individuals. Watch the short Still Face experiment, which illustrates what happens when the caretaker is not responding to the infant’s communication.

Recommendation. Do not use cellphone and digital media while being with an infant in the first two years of life. It is important for caregivers to limit their cellphone use and prioritize reciprocal interactions with their infants for healthy emotional and psychological development.

Reduce screen time (television, social media, streaming videos, gaming)[1]

From an evolutionary perspective, screen time is an entirely novel experience.  Television, computers, and cellphones are modern technologies that have significantly impacted infants’ and young people’s development. To grow, infants, toddlers, and children require opportunities to explore the environment through movement, touch, and play with others, which is not possible with screens. Research has shown that excessive screen time can negatively affect children’s motor development, attention span, socialization skills, and contribute to obesity and other health problems (Hinkley et al., 2014; Carson et al., 2016; Mark, 2023).

When four-year-olds watch fast-paced videos, they exhibit reduced executive functions and impulse control, which may be a precursor for ADHD, compared to children who engage in activities such as drawing (Lillard & Peterson, 2011; Mark, 2023).

Furthermore, excessive screen time and time spent on social media are causal in increasing depression in young adults-–as was discovered when Facebook became available at selected universities. Researchers compared the mental health of students at similar universities where Facebook was or was not available and observed how the students’ mental health changed when Facebook became available (Braghieri et al., 2022). Their research showed that “College-wide access to Facebook led to an increase in severe depression by 7% and anxiety disorders by 20%. In total, the negative effect of Facebook on mental health appeared to be roughly 20% the magnitude of what is experienced by those who lose their job” (Walsh, 2022).

Exposure to digital media has also significantly reduced our attention span from 150 seconds in 2004 to an average of 44 seconds in 2021. The shortening of attention span may contribute to the rise of ADHD and anxiety (Mark, 2022, p. 96).

Recommendations:  Reduce time spent on social media, gaming, mindlessly following one link after the other, or watching episode after episode of streaming videos. Instead, set time limits for screen use, turn off notifications, and prioritize in-person interactions with friends, family and colleagues while engaging in collaborative activities. Encourage children to participate in physical and social activities and to explore nature.

To achieve this, follow the guidelines from the American Academy of Pediatrics’ recommendation on screen time (Council on Communications and Media, 2016), which suggest these limits on screen time for children of different age groups:

  • Children under 18 months of age should avoid all screen time, except for video chatting with family and friends.
  • Children aged 18-24 months should have limited screen time, and only when watched together with a caretaker.
  • Children aged 2 to 5 years should have no more than one hour of screen time per day with parental supervision.
  • For adolescents, screen and social media time should be limited to no more than an hour a day.

In our experience, when college students reduce their time spent on social media, streaming videos, and texting, they report that it is challenging; however, they then report an increase in well-being and performance over time (Peper et al., 2021). It may require more effort to provide children with actual experiential learning and entertainment than allowing them to use screens, but it is worthwhile.  Having children perform activities and play outdoors–in a green nature environment–appears to reduce ADHD symptoms (Louv, 2008; Kuo & Taylor, 2004).

Reestablish circadian (daily) rhythms

Our natural biological and activity rhythms were regulated by natural light until the 19th century. It is hard to imagine not having light at night to read, to work on the computer, or to answer email. However, light not only illuminates, but also affects our physiology by regulating our biological rhythms. Exposure to light at night can interfere with the production of melatonin, which is essential for sleep.  Insufficient sleep affects 30% of toddlers, preschoolers, and school-age children, as well as the majority of adolescents. The more media is consumed at bedtime, the more bedtime is delayed and total sleep time is reduced (Hale et al., 2018). Reduced sleep is a contributing factor to increased ADHD symptoms of inattention, hyperactivity and impulsivity (Cassoff et al., 2012).

Recommendations: Support the circadian rhythms. Avoid screen time one hour before bedtime. This will reduce exposure to blue light and reduce sympathetic arousal triggered by the content on the screen or reactions to social media and emails. Sleep in total darkness, and establish a regular bedtime and waking time to avoid “social jetlag,” which can negatively affect health and performance (Caliandro et al., 2021). Implement sleep hygiene strategies such as developing a bedtime ritual to improve sleep quality (Stager et al., 2023; Suni, 2023).  Thus, go to bed and wake up at the same time each day, including weekends. Avoid large meals, caffeine, and alcohol before bedtime. Consistency is key to success.

Conclusion

To optimize health, eliminate or reduce those factors that have significantly changed or were not part of our evolutionary past, and explore strategies that support behaviors that have allowed the human being to thrive and survive.

Freedom of movement with the Alexander Technique

Erik Peper and Elyse Shafarman

After taking Alexander Technique lessons I felt lighter and stood taller and I have learned how to direct myself differently.  I am much more aware of my body, so that while I am working at the computer, I notice when I am slouching and contracting. Even better, I know what to do so that I have no pain at the end of the day. It’s as though I’ve learned to allow my body to move freely.

The Alexander Technique is one of the somatic techniques that optimize health and performance (Murphy, 1993). Many people report that after taking Alexander lessons, many organic and functional disorders disappear. Others report that their music or dance performances improve. The Alexander Technique has been shown to improve back pain, neck pain, knee pain walking gait, and balance (Alexander technique, 2022; Hamel, et al, 2016; MacPherson et al., 2015; Preece, et al., 2016). Benefits are not just  physical. Studying the technique decreases performance anxiety in musicians and reduces depression associated with Parkinson’s disease (Klein, et al, 2014; Stallibrass et al., 2002).

Background

The Alexander Technique was developed in the late 19th century by the Australian actor, Frederick Matthias Alexander (Alexander, 2001).  It is an educational method that teaches students to align, relax and free themselves from limiting tension habits (Alexander, 2001; Alexander technique, 2022).  F.M Alexander developed this technique to resolve his own problem of becoming hoarse and losing his voice when speaking on stage.

Initially he went to doctors for treatment but nothing worked except rest. After resting, his voice was great again; however, it quickly became hoarse when speaking.  He recognized that it must be how he was using himself while speaking that caused the hoarseness.  He understood that “use” was not just a physical pattern, but a mental and emotional way of being. “Use” included beliefs, expectations and feelings. After working on himself, he developed the educational process known as the Alexander Technique that helps people improve the way they move, breathe and react to the situations of life.

The benefits of this approach has been documented in a large randomized controlled trial of one-on-one Alexander Technique lessons which showed that it significantly reduced chronic low back pain and the benefits persisted a year after treatment (Little, et al, 2008).  Back pain as well as shoulder and neck pain often is often related to stress and how we misuse ourselves.  When experiencing discomfort, we quickly tend to blame our physical structure and assume that the back pain is due to identifiable structural pathology identified by X-ray or MRI assessments. However, similar structural pathologies are often present in people who do not experience pain and the MRI findings correlate poorly with the experience of discomfort (Deyo & Weinstein, 2001; Svanbergsson et al., 2017). More likely, the causes and solutions involve how we use ourselves (e.g., how we stand, move, or respond to stress). A functional approach may include teaching awareness of the triggers that precede neck and back tension, skills to prevent the tensing of those muscles not needed for task performance,  resolving psychosocial stress and improving the ergonomic factors that contribute to working in a stressed position (Peper, Harvey & Faass, 2020). Conceptually, how we are use ourselves (thoughts, emotions, and body) affects and transforms our physical structure and then our physical structure constrains how we use ourselves.

Watch the video with Alexander Teacher, Elyse Shafarman, who describes the Alexander Technique and guides you through practices that you can use immediately to optimize your health while sitting and moving.

Rest Rusts: Increase dynamic movement to improve health

In hunting and gathering cultures, alternating movement patterns was part of living and essential for health. This shift from dynamic movement to static or awkward positions is illustrated in Figure 1.  

Figure 1. The shift from dynamic movement to immobility and near vision as illustrated by the Hadzabe men in Tanzania returning from a hunt to our modern immobilized work and pleasure positions (Reproduced by permission from Peper, Harvey & Faass, 2020).

Dynamic movement promotes blood and lymph circulation and reduces static pressures.  At present times our work and leisure activities increase  immobility and static positions as we predominantly have shifted to a sitting immobilized position. This significantly increases musculoskeletal discomfort, cardiovascular disease, diabetes etc. The importance of movement as a factor to enhance health is illustrated in the recent findings of 2110 middle aged participants who were followed up for ten years.  Those who took approximately 7000 steps per day or more experienced significantly lower mortality rates compared with participants taking fewer than 7000 steps per day (Paluch et al., 2021). Just having the head forward while looking at the cellphone significantly increases the forces on the muscles holding the head up as illustrated in Figure 2.

Figure 2. The head-forward position puts as much as sixty pounds of pressure on the neck muscles and spine (reproduced by permission from Dr. Kenneth Hansaraj, 2014).

For background and recommendations on what how to reduce static positions, look at our book, TechStress-How technology is hijacking our lives, strategies for coping and pragmatic ergonomics. and the superb article, Static postures are harmful – dynamic postures at work are key to musculoskeletal health, published by the European Agency for Safety and Health at Work (EU-OSHA, Sept 16, 2021) and reproduced below.

Static postures are harmful – dynamic postures at work are key to musculoskeletal health

Our bodies are built for movement – it’s a central part of maintaining a healthy musculoskeletal system and the less we move, the more chance we have of developing health issues including musculoskeletal disorders (MSDs), type 2 diabetes, cardiovascular disease, cancer and more. However, the negative effects of sedentary work can be mitigated by paying attention to the postures we adopt when we work.

Whether workers are standing or seated while working, maintaining a good ergonomic posture is essential when it comes to preventing MSDs. Poor or awkward postures put unnecessary strain on the musculoskeletal system and, over time, can cause the deterioration of muscle fibres and joints.

Poor or awkward postures include those which involve parts of the body not being in their natural position. More muscular effort is needed to maintain unnatural postures, which increases the energy used by the body and can cause fatigue, discomfort and pain. Unnatural postures also put strain on tendons, ligaments and nerves, which increases the risk of injury. For example, the risk of neck pain increases when the neck is rotated more than 45 degrees for more than 25% of the working day.

These postures, including slouching, rotation of the forearms, or prolonged periods of sitting or standing in the same spot, can cause pain in the lower back and upper limbs. The risk increases when combined with repetitive work, static muscle load, or the need to apply force or reach. And even natural or good postures maintained for any length of time become uncomfortable and eventually painful. Everyone has experienced stiffness after being in the same position for any length of time.

What do we mean by ‘good posture’?

For workers, especially those in sedentary jobs such as office work, factory work or driving, it is important to recognise and adopt good postures. A good posture should be comfortable and allow the joints to be naturally aligned. The segments of our body can be divided into three cross-sectional anatomical planes: the sagittal plane, which concerns bending forwards and backwards; the frontal plane, which concerns bending sideways; and finally the transverse plane, which refers to rotation or twisting of the body parts. A good posture is one that ensures that all three of these planes are set at neutral positions as much as possible, in that the worker is not leaning backwards, forwards or to any particular side, and their limbs and torso are not rotated or twisted. Adopting neutral postures will help to lessen the strain on the worker’s muscles, tendons and skeletal system, and reduces the risk of them causing or aggravating an MSD.

In practice, workers can consider the following checklist to ensure that they’re standing or sitting in a neutral position:

  • Keep the neck vertical and the back in an upright position.
  • Ensure the elbows are below the chest and avoid having to reach excessively.
  • Keep the shoulders relaxed and use back and arm rests where possible and ensure that they are adjusted to the size and shape of the worker.
  • Avoid rotating the forearms or excessively moving the wrists.
  • Ensure that any work tools can be held comfortably, and that clothing doesn’t restrain or prevent movement.
  • Allow room to comfortably move the legs and feet and avoid frequent kneeling or squatting.
  • Ensure that long periods of standing or sitting in the same posture can be broken up.

Employers can assist workers in adopting good postures by communicating checklists such as this one, and by promoting physical activity where possible, encouraging the fair rotation of tasks between employees to avoid them consistently making repetitive movements, and ensuring that workers have the capacity to take regular breaks.

Why our next posture is the best posture

However, maintaining a good posture at all times is not enough to reduce the risk of MSDs, and can even be harmful. Static postures, even if ergonomic, are still a risk factor if over-used. Our body requires movement and variety, which is why the best approach is to use a variety of ergonomic postures in rotation, breaking up long periods of static working with stretching, exercise, and movement. This is known as adopting dynamic positions’.

It is important not only for workers who spend much of their day seated, but also for workers who primarily stand – such as factory workers in assembly lines. In both cases, sitting and standing are not opposites. The opposite of both is movement. Changing postures between sitting and standing is not sufficient for any worker – the working environment must still offer ways of varying their postures and incorporating movement into their daily working routines. What’s more, if standing work cannot be avoided, workers do not need lots of space in order to adopt dynamic positions in a healthy way. Blood flow propulsion mechanisms can still work correctly even if the worker is only moving around in one square metre. However it is still the case that they should have a break after 30 minutes of standing.

Work should therefore not only facilitate good postures, but ensure that good, ergonomic postures are also dynamic. Switching between sitting, standing and moving while ensuring that the musculoskeletal frame is not under any unnecessary tension can help sedentary workers avoid the onset of MSDs and other health problems.

Improve learning with peak performance techniques

Erik Peper, PhD and Vietta Wilson, PhD

Adapted from: Peper, E. & Wilson, V. (2021). Optimize the learning state: techniques and habits. Biofeedback, 9(2), 46-49. https://doi.org/10.5298/1081-5937-49-2-04

Long after the COVID-19 pandemic is over, online learning will continue to increase as better methodologies and strategies are developed to implement and integrate it into our lives. This post provides suggestions on how to enhance the learner’s ability to engage while online with the use of pre-performance routines or habits.

Facilitating online learning requires coordination of the teacher, technology, student, environment and the topic. Teachers can enhance engagement (Shoepe et al., 2020) online through different types of prompts: intellectual (associated with instructor interaction, academic challenge, active learning), organizational (associated with enriching academic experiences by directing students, selecting topics and summarizing or redirecting), and social (associated with supportive campus environments by encouraging social interaction, using informal language and affirming student comments).

The student can enhance the satisfaction and quality of the online experience by having a good self-regulated learning style. Learning is impacted by motivation (beliefs about themselves or the task, perceived value, etc.), and metacognition (ability to plan, set goals, monitor and regulate their behavior and evaluate their performance) (Greene & Azevedo, 2010; Mega et al., 2014). While critical for learning, it does not provide information on how students can maintain their optimized performance long term, which is increasingly necessary during the pandemic but will possibly be the model of education and therapy of the future.

Habit can enhance performance across a life span.

Habit is a behavioral tendency tied to a specific context, such as learning to brush one’s teeth while young and continuing through life (Fiorella, 2020). Habits are related to self-control processes that are associated with higher achievement (Hagger, 2019). Sport performance extensively values habit, typically called pre-performance routine, in creating an ongoing optimized state of performance (Lautenbach et al., 2015; Lidor & Mayan, 2005; Mesagno et al., 2015). Habits or pre-performance routines are formed by repeating a behavior tied to a specific context and with continued repetition, wherein the mental association between the context and the response are strengthened. This shifts from conscious awareness to subconscious behavior that is then cued by the environment. The majority of one’s daily actions and behaviors are the results of these habits.

Failure to create a self-regulated learning habit impedes long-term success of students. It does take significant time and reinforcement to create the automaticity of a real-life habit. Lally et al. (2010) tracked real world activities (physical activity, eating, drinking water) and found habit formation varied from 18-254 days with a mean of 66 days. There was wide variability in the creation of the habit and some individuals never reached the stage of automaticity. Interestingly, those who performed the behavior with greater consistency were more likely to develop a habit.

The COVID pandemic resulted in many people working at home, which interrupted many of the covert habit patterns by which they automatically performed their tasks. A number of students reported that everything is the same and that they are more easily distracted from doing the tasks. As one student reported:

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.

By having rituals and habits trigger behavior, it is easier to initiate and perform tasks. Students can use the strategies developed for peak performance in sports to optimize their performances so that they can achieve their personal best (Wilson & Peper, 2011; Peper et al., 2021). These strategies include environmental cueing and personal cueing.

By taking charge of your environment and creating a unique environment for each task, it is possible to optimize performance specific for each task. After a while, we do not have to think to configure ourselves for the task. It is no different than the sequence before going to sleep: you brush your teeth and if you forget, it feels funny and you probably will get up to brush your teeth.

Previously, many people, without awareness, would configure and reinforce themselves for work by specific tasks such as commuting to go work, being at a specific worksite to perform the work, wearing specific clothing, etc. (Peper et al., 2021). Now there are few or no specific cues tied to working; it tends to be all the same and it is no wonder that people feel less energized and focused.

Many people forget that learning and recall are state-dependent to where the information was acquired. The Zoom environment where we work or attend class is the same environment where we socialize, game, watch videos, message, surf the net and participate in social media. For most, there has been no habit developed for the new reality of in-home learning. To do this, the environment must be set up so the habit state (focused, engaged) is consistently paired with environmental, emotional, social and kinesthetic cues. The environment needs to be reproducible in many locations, situations, and mental states as possible. As illustrated by one student’s report.

To cue myself to get ready for learning, I make my cappuccino play the same short piece of music, wear the same sweater, place my inspiring poster behind my screen, turn off all software notifications and place the cell phone out of visual range.

A similar concept is used in the treatment of insomnia by making the bedroom the only room to be associated with sleep or intimacy (Irish et al., 2017; Suni, 2021). All other activities, arguing with your partner, eating, watching television, checking email, texting, or social media are done at other locations. Given enough time, the cues in the bedroom become the conditioned triggers for sleep and pleasure.

Create different environments that are unique to each category of Zoom involvement (studying, working, socializing, entertaining).

Pre COVID, we usually wore different clothing for different events (work versus party) or visited different environments for different tasks (religious locations for worship; a bar, coffee shop, or restaurant for social gathering). The specific tasks in a specified location had conscious and subconscious cues that included people, 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 when the bell sound was paired with the presentation of meat. Taking charge of the conditioning process at home may help many people to focus on their task as so many people now use their bedroom, kitchen or living room for Zoom work that is not always associated with learning or work. The following are suggestions to create working/learning environments.

  • Wear task-specific clothing just as you would have done going to work or school. When you plan to study or work, put on your work shirt. In time, the moment you put on the work shirt, you are cueing yourself to focus on studying/working. When finishing with working/studying, change your clothing.
  • If possible, maintain a specific location for learning/working. When attending classes or working, sit at your desk with the computer on top of the desk. For games or communication tasks, move to another location.
  • If you can’t change locations, arrange task-specific backgrounds for each category of Zoom tasks. Place a different background such as a poster or wall hanging behind the computer screen—one for studying/working, and another for entertainment. When finished with the specific Zoom event, take down the poster and change the background.
  • Keep the sound appropriate to the workstation area. Try to duplicate what is your best learning/working sound scape.

Personal Cueing

Learning to become aware of and in control of one’s personal self is equally or more important than setting up the environment with cues that foster attention and learning. Practicing getting the body/mind into the learning state can become a habit that will be available in many different learning situations across one’s lifespan.

  • Perform a specific ritual or pre-performance routine before beginning your task to create the learning/performing state. The ritual is a choreographed sequence of actions that gets you ready to perform. For example, some people like to relax before learning and find playing a specific song or doing some stretching before the session is helpful.  Others sit at the desk, turn off all notifications, take a deep breath then look up and state to themselves: “I am now looking forward to working/studying and learning,” “focus” (whatever it may be). For some, their energy level is low and doing quick arm and hand movements, slapping their thighs or face, or small fast jumps may bring them to a more optimal state. For many people smell and taste are the most powerful conditioners, and coffee improves their attention level. Test out an assortment of activities that get your body and mind at the performance level. Practice and modify as necessary.

Just as in sport, the most reliable method is to set up oneself for the learning/performance state, because a person has less control over the environment. For example, when I observed the Romanian rhythmic gymnasts team members practice their routine during the warmup before the international competition, they would act as if it was the actual competition. They stood at the mat preparing their body/mind state, then they would bow to the imaginary judge, wait for a signal to begin, and then perform their routine. On the other hand, most of the American rhythmic gymnasts would just do their practice routine. For the Romanian athletes, the competition was the same as their rehearsal practice. No wonder, the Romanian athletes were much more consistent in their performance. Additionally, ritual helps buffer against uncertainty and anxiety (Hobson et al., 2017).

  • Develop awareness of the body-mind state associated with optimum performance. This can be done by creating a ritual and an environment that evoke the optimum mental and emotional state for learning. As you configure yourself and your environment, explore how you physically feel when you are most focused and engaged. Identify what your posture, muscle tension, and body position feel like during these times, and identify what you are paying attention to. If your attention wanders, observe how you bring your attention back to the task. Does it help focus you to write summary notes or doodle? Do you flag important statements in your head and then visibly nod your head when you understand the concept? Or do you repeat an important cue word?  Find what you do when you are optimally functioning. Then try to reproduce that same state that can be triggered by a key word that tells you what to focus on (e.g., listen to teacher, look at slide, etc.).

In summary, by becoming aware of and controlling one’s environment and personal states that are associated with productive learning, and then practicing them until they become a routine or habit, one can maximize all learning opportunities. This blog presented a few tips, techniques and cues that may help one to maximize attention and increase performance and learning while online.

I noticed when I took the time to prepare and ready myself to be focused and be present during the class, I no longer had to actively work to resist distractions; I was focused in the moment and not worried about emails, other assignments, what to make for dinner, etc…

Reactivate your second heart

Monica Almendras and Erik Peper

Adapted from: Almendras, M. & Peper, E. (2021). Reactivate your second heart. Biofeedback, 49(4), 99-102. https://doi.org/10.5298/1081-5937-49.04.07

Have you ever wondered why after driving long distances or sitting in a plane for hours your feet and lower leg are slightly swollen (Hitosugi, Niwa, & Takatsu, 2000)? It is the same process by which soldiers standing in attention sometimes faint or why salespeople or cashiers, especially those who predominantly stand most of the day, have higher risk of developing varicose veins.  By the end of the day, they feel that their legs being heavy and tired?  In the vertical position, gravity is the constant downward force that pools venous blood and lymph fluid in the legs. The pooling of the blood and reduced circulation is a contributing factor why airplane flights of four or more hours increases the risk for developing blood clots-deep vein thrombosis (DVT) (Scurr, 2002; Kuipers et al., 2007).  When blood clots reaches the lung, they can cause a pulmonary embolisms that can be fatal. In other cases, they may even travel to the brain and cause strokes.[1]  

Sitting without moving the leg muscles puts additional stress on your heart, as the blood and lymph pools in the legs. Tightening and relaxing the calf muscles can prevent the pooling of the blood.  The inactivity of your calf muscles does not allow the blood to flow upwards. The episodic contractions of the calf muscles squeezes the veins and pumps the venous blood upward towards the heart as illustrated in figure 1.  Therefore, it is important to stand, move, and walk so that your calf muscle can act as a second heart (Prevosti, April 16, 2020). 

Figure 1. Your calf muscles are your second heart! The body is engineered so that when you walk, the calf muscles pump venous blood back toward your heart. Reproduced by permission from Dr. Louis Prevosti of the Center for Vein Restoration (https://veinatlanta.com/your-second-heart/).

To see the second heart in action watch the YouTube video, Medical Animation Movie on Venous Disorders, by the Sigvaris Group Europe (2017).

If you stand too long and experienced slight swelling of the legs, raise your feet slightly higher than the head, to help drain the fluids out of the legs.  Another way to reduce pooling of fluids  and prevent blood clots and edema is to wear elastic stockings or wrap the legs with intermittent pneumatic compression (IPC) devices that periodically compresses the leg (Zhao et al., 2014). You can also do this by performing foot rotations or other leg and feet exercises. The more the muscle of the legs and feet contract and relax, the more are the veins episodically compressed which increases venous blood return.  Yet in our quest for efficiency and working in front of screens, we tend to sit for long time-periods.

Developing sitting disease

Have you noticed how much of the time you sit during the day? We sit while studying, working, socializing and entertaining in front of screens. This sedentary behavior has significantly increased during the pandemic (Zheng et al, 2010). Today, we do not need to get up because we call on Amazon’s Alexa, Apple’s Siri or Google’s Hey Google to control timers, answer queries, turn on the lights, fan, TV, and other home devices. Everything is at our fingertips and we have finally become The Jetsons without the flying cars (an American animated sitcom aired in the 1960s). There is no need to get up from our seat to do an activity. Everything can be controlled from the palm of our hand with a mobile phone app. 

With the pandemic, our activities involve sitting down with minimum or no movement at all. We freeze our body’s position in a scrunch–a turtle position–and then we wonder why we get neck, shoulder, and back pains–a process also observed in young adults or children. Instead of going outside to play, young people sit in front of screens. The more we sit and watch screens, the poorer is our mental and physical health (Smith et al., 2020Matthews et al., 2012). We are meant to move instead of sitting in a single position for eight or more hours while fixating our attention on a screen.

The visual stimuli on screen captures our attention, whether it is data entry, email, social media, or streaming videos (Peper, Harvey & Faass, 2020).  While at the computer, we often hold up our index finger on the mouse and wait with baited breath to react.  Holding this position and waiting to click may look harmless; however, our right shoulder is  often elevated and raised upward towards our ear. This bracing pattern is covert and contributes to the development of discomfort. The moment your muscles tighten, the blood flow through the muscle is reduced (Peper, Harvey, & Tylova, 2006). Muscles are most efficient when they alternately tighten and relax. It is no wonder that our body starts to scream for help when feeling pain or discomfort on our neck, shoulders, back and eyes.

Why move?

Figure 2a and 2b Move instead of sit (photos source: Canva.com).

The importance of tightening and then relaxing muscles is illustrated during walking.  During the swing phase of walking, the hip flexor muscles relax, tighten, relax again, tighten again, and this is repeated until the destination is reached. It is important to relax the muscles episodically for blood flow to bring nutrients to the tissue and remove the waste product.  Most people can walk for hours; however, they can only lift their foot from the floor (raise their leg up for a few minutes) till discomfort occurs. 

Movement is what we need to do and play is a great way to do it. Dr. Joan Vernikos (2016) who conducted seminal studies in space medicine and inactivity physiology investigated why astronauts rapidly aged in space and lost muscle mass, bone density and developed a compromised immune system. As we get older, we are hooked on sitting, and this includes the weekends too. If you are wondering how to separate from your seat, there are ways to overcome this. In the research to prevent the deterioration caused by simulating the low gravity experience of astronauts, Dr. Joan Vernikos (2021) had earthbound volunteers lie down with the head slightly lower than the feet on a titled bed. She found that standing up from lying down every 30-minutes was enough to prevent the deterioration of inactivity, standing every hour was not enough to reverse the degeneration.  Standing stimulated the baroreceptors in the neck and activated a cardiovascular response for optimal health (Vernikos, 2021).

We have forgotten something from our evolutionary background and childhood, which is to play and move around.  When children move around, wiggle, and contort themselves in different positions, they maintain and increase their flexibility. Children can jump and move their arms up, down, side to side, forward, and backward. They do this every day, including the weekends.

When was the last time you played with a child or like a child? As an adult, we might feel tired to play with a child and it can be exhausting after staring at the screen all day. Instead of thinking of being tired to play with your child, consider it as a good workout. Then you and your child bond and hopefully they will also be ready for a nap. For you, not only do you move around and wake up those muscles that have not worked all day, you also relax the tight muscles, stretch and move your joints. Do playful activities that causes the body to move in unpredictable fun ways such as throwing a ball or roleplaying being a different animal. It will make both of you smile–smiling helps relaxation and rejuvenates your energy.

It is not how much exercise you do, it is how long you sit.  The longer you sit without activating your second heart the more are you at risk for cardiovascular disease and diabetes independent of how much exercise you do (Bailey et al., 2019).

Use it or lose it! Activate your calves!

  • Interrupt sitting at your desk/computer every 30-minutes by getting up and walking around.
  • Stand up and walk around when using your phone.
  • Organize walking meetings instead of sitting around a table.
  • Invest in a sit-stand desk while working at the computer.  While working, alternate positions. There should be a balance between standing and sitting, because too much of one can lead to problems. By taking a short standing up break to let your blood pump back to the heart is beneficial to avoid health problems. Exercise alone, a fancy new ergonomic chair or expensive equipment is not enough to be healthy, it is important to add those mini breaks in between (Buckley et al, 2015).

Are you encouraging your child to get into accidents or even blind when growing up?

Erik Peper and Meir Schneider

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)

  • 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).

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.
