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.
Environmental 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…

Digital fatigue and what to do
Posted: July 22, 2021 Filed under: Uncategorized 1 CommentErik 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.
Reduce your risk of COVID-19 variants and future pandemics
Posted: July 5, 2021 Filed under: behavior, health, Nutrition/diet, self-healing | Tags: COVID-19, immune, pandemic, prevention, vitamin D 2 CommentsErik Peper, PhD and Richard Harvey, PhD
The number of hospitalizations and deaths from COVID-19 are decreasing as more people are being vaccinated. At the same time, herd immunity will depend on how vaccinated and unvaccinated people interact with one another. Close-proximity, especially indoor interactions, increases the likelihood of transmission of coronavirus for unvaccinated individuals. During the summer months, people tend to congregate outdoors which reduces viral transmission and also increases vitamin D production which supports the immune system (Holick, 2021)..
Most likely, COVID-19 disease will become endemic because the SARS-CoV-2 virus will continue to mutate. Already Pfizer CEO Albert Bourla stated on April 15, 2021 that people will “likely” need a third dose of a Covid-19 vaccine within 12 months of getting fully vaccinated. Although, at this moment the vaccines are effective against several variants, we need to be ready for the next COVID XX outbreak.
To reduce future infections, the focus of interventions should 1) reduce virus exposure, 2) vaccinate to activate the immune system, and 3) enhance the innate immune system competence. The risk of illness may relate to virus density exposure and depend upon the individual’s immune competence (Gandhi & Rutherford, 2020; Mukherjee, 2020) which can be expressed in the following equation.
Reduce viral load (hazardous exposure)
Without exposure to the virus and its many variants, the risk is zero which is impossible to achieve in democratic societies. People do not live in isolated bubbles but in an interconnected world and the virus does not respect borders or nationalities. Therefore, public health measures need to focus upon strategies that reduce virus exposure by encouraging or mandating wearing masks, keeping social distance, limiting social contact, and increasing fresh air circulation.
Wearing masks reduces the spread of the virus since people may shed viruses one or two days before experiencing symptoms (Lewis et al., 2021). When a person exhales through the mask, a good fitting N95 mask will filter out most of the virus and thereby reduce the spread of the virus during exhalation. To protect oneself from inhaling the virus, the mask needs be totally sealed around the face with the appropriate filters. Systematic observations suggest that many masks such as bandanas or surgical masks do not filter out the virus (Fisher et al., 2020).
Fresh air circulation reduces the virus exposure and is more important than the arbitrary 6 feet separation (CDC, May 13, 2021). If separated by 6 feet in an enclosed space, the viral particles in the air will rapidly increase even when the separation is 10 feet or more. On the other hand, if there is sufficient fresh air circulation, even three feet of separation would not be a problem. The spatial guidelines need to be based upon air flow and not on the distance of separation as illustrated in the outstanding graphical modeling schools by Nick Bartzokas et al. (February 26, 2021) in the New York Times article, Why opening windows is a key to reopening schools.
The public health recommendations of sheltering-in-place to prevent exposure or spreading the virus may also result in social isolation. Thus, shelter-in-place policies have resulted in compromising physical health such as weight gain (e.g. average increase of more than 7lb in weight in America according to Lin et al., 2021), reduced physical activity and exercise levels (Flanagan et al., 2021) and increased anxiety and depression (e.g. a three to four fold increase in the self-report of anxiety or depression according to Abbott, 2021). Increases in weight, depression and anxiety symptoms tend to decrease immune competence (Leonard, 2010). In addition, the stay at home recommendations especially in the winter time meant that individuals are less exposed to sunlight which results in lower vitamin D levels which is correlated with increased COVID-19 morbidity (Seheult, 2020).
Increase immune competence
Vaccination is the primary public health recommendation to prevent the spread and severity of COVID-19. Through vaccination, the body increases its adaptive capacity and becomes primed to respond very rapidly to virus exposure. Unfortunately, as Pfizer Chief Executive Albert Bourla states, there is “a high possibility” that emerging variants may eventually render the company’s vaccine ineffective (Steenhuysen, 2021). Thus, it is even more important to explore strategies to enhance immune competence independent of the vaccine.
Public Health policies need to focus on intervention strategies and positive health behaviors that optimize the immune system capacity to respond. The research data has been clear that COVID -19 is more dangerous for those whose immune systems are compromised and have comorbidities such as diabetes and cardiovascular disease, regardless of age.
Comorbidity and being older are the significant risk factors that contribute to COVID-19 deaths. For example, in evaluating all patients in the Fair Health National Private Insurance Claims (FH NPIC’s) longitudinal dataset, researchers identified 467,773 patients diagnosed with COVID-19 from April 1, 2020, through August 31, 2020. The severity of the illness and death from COVID-19 depended on whether the person had other co-morbidities first as shown in Figure 1.
Figure 1. The distribution of patients with and without a comorbidity among all patients diagnosed with COVID-19 (left) and all deceased COVID-19 patients (right) April-August 2020. Reproduced by permission from: https://www.ajmc.com/view/contributor-links-between-covid-19-comorbidities-mortality-detailed-in-fair-health-study
Each person who died had about 2 or 3 types of pre-existing co-morbidities such as cardiovascular disease, hypertension, diabetes, obesity, congestive heart failure, chronic kidney disease, respiratory disease and cancer (Ssentongo et al., 2020; Gold et al., 2020). The greater the frequency of comorbidities the greater the risk of death, as shown in Figure 2.

Although the risk of serious illness and death is low for young people, the presence of comorbidity increases the risk. Kompaniyets et al. (2021) reported that for patients under 18 years with severe COVID-19 illness who required ICU admission, mechanical ventilation, or died most had underlying medical conditions such as asthma, neurodevelopmental disorders, obesity, essential hypertension or complex chronic diseases such as malignant neoplasms or multiple chronic conditions.
Consistent with earlier findings, the Fair Health National Private Insurance Claims (FH NPIC’s) longitudinal dataset also showed that the COVID-19 mortality rate rose sharply with age as shown in Figure 3.

Optimize antibody response from vaccinations
Assuming that the immune system reacts similarly to other vaccinations, higher antibody response is evoked when the vaccine is given in the morning versus the afternoon or after exercise (Long et al., 2016; Long et al., 2012). In addition, the immune response may be attenuated if the person suppresses the body’s natural immune response–the flulike symptoms which may occur after the vaccination–with Acetaminophen (Tylenol (Graham et al, 1990).
Support the immune system with a healthy life style
Support the immune system by implementing a lifestyle that reduces the probability of developing comorbidities. This means reducing risk factors such as vaping, smoking, immobility and highly processed foods. For example, young people who vape experience a fivefold increase to become seriously sick with COVID-19 (Gaiha, Cheng, & Halpern-Felsher, 2020); similarly, cigarette smoking increases the risk of COVID morbidity and mortality (Haddad, Malhab, & Sacre, 2021).
There are many factors that have contributed to the epidemic of obesity, diabetes, cardiovascular disease and other chronic diseases. In many cases, the environment and lifestyle factors (lack of exercise, excessive intake of highly processed foods, environmental pollution, social isolation, stress, etc.) significantly contribute to the initiation and development of comorbidities. Genetics also is a factor; however, the generic’s risk factor may not be triggered if there are no environmental/behavioral exposures. Phrasing it colloquially, Genetics loads the gun, environment and behavior pulls the trigger. Reducing harmful lifestyle behaviors and environment is not simply an individual’s responsibility but a corporate and governmental responsibility. At present, harmful lifestyles choices are actively supported by corporate and government policies that choose higher profits over health. For example, highly processed foods made from corn, wheat, soybeans, rice are grown by farmers with US government farm subsidies. Thus, many people especially of lower economic status live in food deserts where healthy non-processed organic fruits and vegetable foods are much less available and more expensive (Darmon & Drewnowski, 2008; Michels, Vynckier, Moreno, L.A. et al. 2018; CDC, 2021). In the CDC National Health and Nutrition Examination Survey that analyzed the diet of 10,308 adults, researchers Siegel et al. (2016) found that “Higher consumption of calories from subsidized food commodities was associated with a greater probability of some cardiometabolic risks” such as higher levels of obesity and unhealthy blood glucose levels (which raises the risk of Type 2 diabetes).
Immune competence is also affected by many other factors such as exercise, stress, shift work, social isolation, and reduced micronutrients and Vitamin D (Zimmermann & Curtis, 2019). Even being sedentary increases the risk of dying from COVID as reported by the Kaiser Permanente Southern California study of 50,000 people who developed COVID (Sallis et al., 2021).
People who exercised 10 minutes or less each week were hospitalized twice as likely and died 2.5 times more than people who exercised 150 minutes a week (Sallis et al., 2021). Although exercise tends to enhance immune competence (da Silveira et al, 2020), it is highly likely that exercise is a surrogate marker for other co-morbidities such as obesity and heart disease as well as aging. At the same time sheltering–in-place along with the increase in digital media has significantly reduced physical activity.
The importance of vitamin D
Low levels of vitamin D is correlated with poorer prognosis for patients with COVID-19 (Munshi et al., 2021). Kaufman et al. (2020) reported that the positivity rate correlated inversely with vitamin D levels as shown in figure 4.
Figure 4. SARS-CoV-2 NAAT positivity rates and circulating 25(OH)D levels in the total population. From: Kaufman, H.W., Niles, J.K., Kroll, M.H., Bi, C., Holick, M.F. (2020). SARS-CoV-2 positivity rates associated with circulating 25-hydroxyvitamin D levels. PLoS One. 15(9):e0239252. https://doi.org/10.1371/journal.pone.0239252
Vitamin D is a modulator for the immune system (Baeke, Takiishi, Korf, Gysemans, & Mathieu, 2010). There is an inverse correlation of all-cause, cardiovascular, cancer, and respiratory disease mortality with hydroxyvitamin D concentrations in a large cohort study (Schöttker et al., 2013). For a superb discussion about how much vitamin D is needed, see the presentation, The D-Lightfully Controversial Vitamin D: Health Benefits from Birth until Death, by Dr. Michael F. Holick, Ph.D., M.D. from the University Medical Center Boston.
Low vitamin D levels may partially explain why in the winter there is an increase in influenza. During winter time, people have reduced sunlight exposure so that their skin does not produce enough vitamin D. Lower levels of vitamin D may be a cofactor in the increased rates of COVID among people of color and older people. The darker the skin, the more sunlight the person needs to produce Vitamin D and as people become older their skin is less efficient in producing vitamin D from sun exposure (Harris, 2006; Gallagher, 2013). Vitamin D also moderates macrophages by regulating the release, and the over-release of inflammatory factors in the lungs (Khan et al., 2021).

What can be done NOW to enhance immune competence?
We need to recognize that once the COVID-19 pandemic has passed, it does not mean it is over. It is only a reminder that a new COVID-19 variant or another new virus will emerge in the future. Thus, the government public health policies need to focus on promoting health over profits and aim at strategies to prevent the development of chronic illnesses that affect immune competence. One take away message is to incorporate behavioral medicine prescriptions supporting a healthy lifestyle into treatment plans, such as prescribing a walk in the sun to increase vitamin D production and develop dietary habits of eating organic locally grown vegetable and fruits foods. Even just reducing the refined sugar content in foods and drinks is challenging although it may significantly reduce incidence and prevalence of obesity and diabetes (World Health Organization, 2017. The benefits of such an approach has been clearly demonstrated by the Pennsylvania-based Geisinger Health System’s Fresh Food Farmacy. This program for food-insecure people with Type 2 diabetes and their families provides enough fresh fruits and vegetables, whole grains, and lean proteins for two healthy meals a day five days a week. After one year there was a 40 percent decrease in the risk of death or serious complications and an 80 percent drop in medical costs per year (Brody, 2020).
The simple trope of this article ‘eat well, exercise and get good rest’ and increase your immune competence concludes with some simple reminders.
- Increase availability of organic foods since they do not contain pesticides such as glyphosate residue that reduce immune competence.
- Increase vegetable and fruits and reduce highly processed foods, simple carbohydrates and sugars.
- Decrease sitting and increase movement and exercise
- Increase sun exposure without getting sunburns
- Master stress management
- Increase social support

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.

Reactivate your second heart

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., 2020; Matthews 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?

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 commentFresh 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).
