“Instead of zoning out and being on my phone half the time. I felt more engaged in the class and like I was actually learning something.” -21 year old college student
Before the pandemic, roughly, two-thirds of all social interactions were face-to-face—and when the shelter-in-place order hit our communities, we were all faced with the task of learning how to engage virtually. The majority of students reported that taking online classes instead of in person classes is significantly more challenging. It is easier to be distracted and multitask online—for example, looking at Instagram, Facebook, Twitter, TikTok, texting, surfing the internet, responding to notifications, listening to music, or drifting to sleep. Hours of watching TV and/or streaming videos have conditioned many people to sit and take in information passively, which discourages them from actively responding or initiating. The information is rapidly forgotten when the next screen image or advertisement appears. Effectively engaging on Zoom requires a shift from passively watching and listening to being an active, creative participant.
Another barrier to virtual engagement is that communicating online does not engage all senses. A considerable amount of our communication is nonverbal—sounds, movement, visuals, physical structures, touch, and body language. Without these sensory cues, it can be difficult to feel socially connected on Zoom, Microsoft Teams, or Google Meet to sustain attention and to focus especially if there are many people in the class or meeting. Another challenge to virtual learning is that without the normal environment of a classroom, many students across the country are forced to learn in emotionally and/or physically challenging environments, which gets in the way of maintaining attention and focus. The Center for Disease Prevention (CDC) reported that anxiety disorder and depressive disorder have increased considerably in the United States during the COVID-19 pandemic (Leeb et al, 2020; McGinty et al, 2020). Social isolation, stay-at-home orders, and coping with COVID-19 are contributing factors affecting mental health especially for minority and ethnic youth. Stress, anxiety and depression can greatly affect students’ ability to learn and focus.
The task of teaching has also become more stressful since many students are not visible or appear still-faced and non-responsive. Teaching to non-responsive faces is significantly more stressful since the presenter receives no social feedback. The absence of social feedback during communication is extremely stressful. It is the basis of Trier Social stress test in which a person presents for five minutes to a group of judges who provide no facial or verbal feedback (Allen et al, 2016; Peper, 2020).
The Zoom experience especially in a large class can be a no win situation for the presenter and the viewer. To help resolve this challenge, we explored a strategy to increase student engagement and reduce social stress of the teacher. In this exploration, we asked students to rate their subjective energy level, attention and involvement during a Zoom conducted class. For the next Zoom class, they were asked to respond frequently with facial and body expressions to the presentation. For example, students would expressively shake their head no or yes and/or use facial expressions to signal to the teacher that they were engaged and listening. Other strategies included giving thumbs up or thumbs down, making sounds, and changing your body posture as a response to the presentation. Watch the superb non-judgmental instructions adapted for high school students by Amber Yang.
When college students purposely implement animated facial and body responses during Zoom classes, they report a significant increase in frequency of animation (ANOVA (F(1,60) = 4.004, p = .0001), energy level (ANOVA (F(1,60) = 4.004, p = .0001), attention (ANOVA (F(1,60) = 4.001, p = .0001) and involvement (ANOVA (F(1,59) = 4.004, p = .002) as compared just attending normally in class (see Figure 1).
Figure 1. Change in subjective energy, attention and involvement when the students significantly increase their facial and body animation by 108% as compared to their normal non-expressive class behavior (from: Peper, Martin, Rosegard, & Harvey, unpublished).
“I never realized how my expressions affected my attention. Class was much more fun” -22 year old college 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
These quotes are a few of the representative reports by more than 80% of the students who observed that being animated and responsive helped them to stay present and learn much more easily and improve retention of the materials. For a few students, it was challenging to be animated as they felt shy, self-conscious and silly and kept wondering what other students would think of them.
Having students compare two different ways of being in Zoom class is a useful assignment since it allows students to discover that being animated and responsive with facial/body expression improves learning. So often we forget how our body impacts our thoughts and emotions. For example, when students were asked to sit in a slouched position, they reported that it was much easier to recall hopeless, helpless, powerless and defeated memories and more difficult to perform mental math in the slouched position. While in the upright position it was easier to access positive empowering memories and easier to perform mental math (Peper et al, 2017; Peper et al, 2018).
Experience how body posture affects emotional recall and feeling (adapted from Alda, 2018).
1) Stand up and configure your body in a position that signals defeat, hopelessness and depression (slouching with the head down). While holding this position, recall a memory of hopelessness and defeat. Notice any negative emotions that arise from this.
2) Shift and configure your body into a position that signals joy, happiness and success (standing tall, looking up with a smile). While holding this position, recall a memory of joy and happiness. Notice any positive emotions that arise from this.
3) Configure your body in a position that signals defeat, hopelessness and depression (slouching with the head down). While holding this position, recall a joy, happiness and success. Do not change your body position. End this configuration after holding it for a little while.
4) Shift and your body in a position that signals joy, happiness and success (standing tall, looking up with a smile). While holding this position, recall a memory of hopelessness and defeat. Do not change your body position. End this configuration after holding it for a little while.
When body posture and expression are congruent with the evoked emotion, it is almost always easier to experience the emotions. On the other hand, when the body posture expression is the opposite of the evoked emotion (e.g., the body in a positive empowered stance while recalling hopeless defeated memories) it is much more difficult to evoke and experience the emotion. This same concept applies to learning. When slouching and lying on the bed while in a Zoom class, it is much more difficult to stay present and not drift off. On the other hand, when sitting erect and upright and actively responding to the presentation, the body presence/posture invites the brain to focus for optimized learning.
In a Zoom environment, it is easy to slouch, drift away, and become non-responsive—which can exacerbate zoom fatigue symptoms and also decrease our capacity to learn, focus, and feel connected with the people around us. Take charge and actively participate in class by sitting up, maintaining an empowered posture, and using nonverbal facial and body expressions to communicate. By engaging our soma we optimize our learning experience as we face the day-to-day challenges of the pandemic and beyond.
I noticed I was able to retain information better as well as enjoy the class more when I used facial-body responses. At times, where I would try to wonder off into bliss, I would catch myself and try to actively engage in the class with body movements even if there is no discussion. Animated face/body was a better learning experience. –21-year old college student.

Dr. Inna Khazan interviews Dr. Rick Harvey about his new book Tech Stress, the way technology overuse can affect adults and children, and what we can do about it.
We are excited about our upcoming book, TechStress-How Technology is Hijacking our Lives, Strategies for Coping and Pragmatic Ergonomics, that will be published August 25, 2020.
Evolution shapes behavior — and as a species, we’ve evolved to be drawn to the instant gratification, constant connectivity, and the shiny lights, beeps, and chimes of our ever-present devices. In earlier eras, these hardwired evolutionary patterns may have set us up for success, but today they confuse our instincts, leaving us vulnerable and stressed out from fractured attention, missed sleep, skipped meals, aches, pains, and exhaustion and often addicted to our digital devices.
Tech Stress offers real, practical tools to avoid evolutionary pitfalls programmed into modern technology that trip us up. You will find a range of effective strategies and best practices to individualize your workspace, reduce physical strain, prevent sore muscles, combat brain drain, and correct poor posture. The book also provides fresh insights on reducing psychological stress on the job, including ways to improve communication with coworkers and family.
Although you will have to wait until August 25th to have the book delivered to your home, you can already begin to implement ways to reduce physical discomfort, zoom/screen fatigue and exhaustion. Have a look the blogs below.

Adapted from the upcoming book, TechStress: How Technology is Hijacking Our Lives, Strategies for Coping, and Pragmatic Ergonomics, by Erik Peper, Richard Harvey and Nancy Faass.
While working in front of screens, many of us suffer from Zoom/screen fatigue, iNeck, shoulder and back discomfort, tired eyes, exhaustion and screen addiction (Peper, 2020; Fosslien & Duffy, 2020; So, Cheng & Szeto, 2017; Peper & Harvey, 2018). As we work, our shoulders and forearms tense and we are often not aware of this until someone mentions it. Many accept the discomfort and pain as the cost of doing work–not realizing that it may be possible to work without pain.
Observe how you and coworkers work at the computer, laptop or cellphone. Often we bring our noses close to the screen in order to the text more clearly and raise our shoulders when we perform data entry and use the mouse. This unaware muscle tension can be identified with physiological recording of the muscles electrical activity when they contract (electromyography) (Peper & Gibney, 2006; Peper, Harvey & Tylova, 2006). In most cases, when we rest our hands on our laps the muscle tension is low but the moment we even rest our hands on the keyboard or when we begin to type or mouse, our muscles may tighten, as shown in Figure 1. The muscle activity will also depend on the person’s stress level, ergonomic arrangement and posture.
Figure 1. Muscle tension from the shoulder and forearm increased without any awareness when the person rested their hands on the keyboard (Rest Keyboard) and during typing and mousing. The muscles only relaxed when the hands were resting on their lap (Rest Lap) (reproduced by permission from Peper, Harvey, and Faass, 2020).
Stop reading from your screen and relax your shoulders. Did you feel them slightly drop and relax?
If you experienced this release of tension and relaxation in the shoulders, then you were tightening your shoulders muscles without awareness. It is usually by the end of the day that we experience stiffness and discomfort. Do the following exercise as guided by the video or described in the text below to experience how discomfort and pain develop by maintaining low-level muscle tension.
While sitting, lift your right knee two inches up so that the foot is about two inches away from the floor. Keep holding the knee up in this position. Did you notice your breathing stopped when you lifted your knee? Are you noticing increasing tension and discomfort or even pain? How much longer can you lift the knee up?
Let go, relax and observe how the discomfort dissipates.
Reasons for the discomfort
The discomfort occurred because your muscles were contracted, which inhibited the blood and lymph flow through the tissue. When your muscles contracted to lift your knee, the blood flow in those muscles was reduced. Only when your muscles relaxed could enough blood flow occur to deliver nutrients and oxygen as well as remove the waste products of metabolism (Wan et al, 2017). From a physiological perspective, muscles work most efficiently when they alternately contract and relax. For example, most people can walk without discomfort since their muscles contract and relax with each step. However, you could hold your knee up for a few minutes before experiencing discomfort in those same muscles.
How to prevent discomfort.
To prevent discomfort and optimize health, apply the same concept of alternating tensing and relaxing to your neck, shoulder, back and arm muscles while working. Every few minutes move your arms and shoulders and let them relax. Interrupt the static sitting position with movement. If you need reminders to get up and move your body during the workday or long periods sitting in front of a device, you can download and install the free app, StretchBreak.
For more information, read and apply the concepts described in our upcoming book, TechStress: How Technology is Hijacking Our Lives, Strategies for Coping, and Pragmatic Ergonomics. The book explains why TechStress develops, why digital addiction occurs, and what you can do to prevent discomfort, improve health and enhance performance.

Forty percent of adults and eighty percent of teenagers report experiencing significant visual symptoms (eyestrain, blurry vision, dry eyes, headaches, and exhaustion) during and immediately after viewing electronic displays. These ‘technology-associated overuse’ symptoms are often labeled as digital eyestrain or computer vision syndrome (Rosenfield, 2016; Randolph & Cohn, 2017). Even our distant vision may be affected— after working in front of a screen for hours, the world looks blurry. At the same time, we may experience an increase in neck, shoulders and back discomfort. These symptoms increase as we spend more hours looking at computer screens, laptops, tablets, e-readers, gaming consoles, and cellphones for work, taking online classes, watching streaming videos for entertainment, and keeping connected with friends and family (Borhany et al, 2018; Turgut, 2018; Jensen et al, 2002).
Eye, head, neck, shoulder and back discomfort are partly the result of sitting too long in the same position and attending to the screen without taking short physical and vision breaks, moving our bodies and looking at far objects every 20 minutes or so. The obvious question is, “Why do we stare at and are captured by, the screen?” Two answers are typical: (1) we like the content of what is on the screen; and, (2) we feel compelled to watch the rapidly changing visual scenes.
From an evolutionary perspective, our sense of vision (and hearing) evolved to identify predators who were hunting us, or to search for prey so we could have a nice meal. Attending to fast moving visual changes is linked to our survival. We are unaware that our adaptive behaviors of attending to a visual or auditory signals activate the same physiological response patterns that were once successful for humans to survive–evading predictors, identifying food, and discriminating between friend or foe. The large and small screen (and speakers) with their attention grabbing content and notifications have become an evolutionary trap that may lead to a reduction in health and fitness (Peper, Harvey & Faass, 2020).
Near vision stress
To be able to see the screen, the eyes need to converge and accommodate. To converge, the extraocular muscles of the eyes tighten; to focus (accomodation), the ciliary muscle around the lens tighten to increase the curvature of the lens. This muscle tension is held constant as long as we look at the screen. Overuse of these muscles results is near vision stress that contributes to computer vision syndrome, development of myopia in younger people, and other technology-associated overuse syndromes (Sherwin et al, 2012; Enthoven et al, 2020).
Continually overworking the visual muscles related to convergences increases tension and contributes to eyestrain. While looking at the screen, the eye muscles seldom have the chance to relax. To function effectively, muscles need to relax /regenerate after momentary tightening. For the eye muscles to relax, they need to look at the far distance– preferably objects green in color. As stated earlier, the process of distant vision occurs by relaxing the extraocular muscles to allow the eyes to diverge along with relaxing the ciliary muscle to allow the lens to flatten. In our digital age, where screen of all sizes are ubiquitous, distant vision is often limited to the nearby walls behind a screen or desk which results in keeping the focus on nearby objects and maintaining muscular tension in the eyes.
As we evolved, we continuously alternated between between looking at the far distance and nearby areas for food sources as well as signals indicating danger. If we did not look close and far, we would not know if a predator was ready to attack us. Today we tend to be captured by the screens. Arguably, all media content is designed to capture our attention such as data entry tasks required for employment, streaming videos for entertainment, reading and answering emails, playing e-games, responding to text notifications, looking at Instagram and Snapchat photos and Tiktok videos, scanning Tweets and using social media accounts such as Facebook. We are unaware of the symptoms of visual stress until we experience symptoms. To illustrate the physiological process that covertly occurs during convergence and accommodation, do the following exercise.
Sit comfortably and lift your right knee a few inches up so that the foot is an inch above the floor. Keep holding it in this position for a minute…. Now let go and relax your leg.
A minute might have seemed like a very long time and you may have started to feel some discomfort in the muscles of your hip. Most likely, you observed that when you held your knee up, you most likely held your breath and tightened your neck and back. Moreover, to do this for more than a few minutes would be very challenging.
Lift your knee up again and notice the automatic patterns that are happening in your body.
For muscles to regenerate they need momentary relaxation which allows blood flow and lymph flow to occur. By alternately tensing and relaxing muscles, they can work more easily for longer periods of time without experiencing fatigue and discomfort (e.g., we can hike for hours but can only lift our knee for a few minutes).
Solutions to relax the eyes and reduce eye strain
- Reestablish the healthy evolutionary pattern of alternately looking at far and near distances to reduce eyestrain, such as:
- Look out through a window at a distant tree for a moment after reading an email or clicking link.
- Look up and at the far distance each time you have finished reading a page or turn the page over.
- Rest and regenerate your eyes with palming. While sitting upright, place a pillow or other supports under our elbows so that your hands can cover your closed eyes without tensing the neck and shoulders.
- 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.
- Close your eyes, imagine seeing black. Breathe slowly and diaphragmatically while feeling the warmth of the palm soothing the eyes. Feel your shoulders, head and eyes relaxing. Palm for 5 minutes while breathing at about six breaths per minute through your nose. Then stretch and go back to work.
Palming is one of the many practices that improves vision. For a comprehensive perspective and pragmatic exercises to reduce eye strain, maintain and improve vision, see the superb book by Meir Schneider, PhD., L.M.T., Vision for Life, Revised Edition: Ten Steps to Natural Eyesight Improvement.
Increased sympathetic arousal
Seeing the changing stimuli on the screen evokes visual attention and increases sympathetic arousal. In addition, many people automatically hold their breath when they see novel visual or hear auditory signals; since, they trigger a defense or orienting response. At the same time, without awareness, we may tighten our neck and shoulder muscles as we bring our nose literally to the screen. As we attend and concentrate to see what is on the screen, our blinking rate decreases significantly. From an evolutionary perspective, an unexpected movement in the periphery could be a snake, a predator, a friend or foe and the body responds by getting ready: freeze, fight or flight. We still react the same survival responses. Some of the physiological reactions that occur include:
- Breath holding or shallow breathing. These often occur the moment we receive a text notification, begin concentrating and respond to the messages, or start typing or mousing. Without awareness, we activate the freeze, flight and fight response. By breath holding or shallow breathing, we reduce or limit our body movements, effectively becoming a non-moving object that is more difficult to see by many animal predators. In addition, during breath holding, hearing become more acute because breathing noises are effectively reduced or eliminated.
- Inhibition of blinking. When we blink it is another movement signal that in earlier times could give away our position. In addition, the moment we blink we become temporarily blind and cannot see what the predator could be doing next.
- Increased neck, shoulder and back tension. The body is getting ready for a defensive fight or avoidance flight.
Experience some of these automatic physiological responses described above by doing the following two exercises.
Eye movement neck connection: While sitting up and looking at the screen, place your fingers on the back of the neck on either side of the cervical spine just below the junction where the spine meets the skull.
Feel the muscles of neck along the spine where they are attaching to the skull. Now quickly look to the extreme right and then to the extreme left with your eyes. Repeat looking back and forth with the eyes two or three times.
What did you observe? Most likely, when you looked to the extreme right, you could feel the right neck muscles slightly tightening and when you looked the extreme left, the left neck muscles slightly tightening. In addition, you may have held your breath when you looked back and forth.
Focus and neck connection: While sitting up and looking at the screen, place your fingers on the back of the neck as you did before. Now focus intently on the smallest size print or graphic details on the screen. Really focus and concentrate on it and look at all the details.
What did you observe? Most likely, when you focused on the text, you brought your head slightly forward and closer to the screen, felt your neck muscles tighten, and possibly held your breath or started to breathe shallowly.
As you concentrated, the automatic increase in arousal, along with the neck and shoulder tension and reduced blinking contributes to developing discomfort. This can become more pronounced after looking at screens to detailed figures, numerical data, characters and small images for hours (Peper, Harvey & Tylova, 2006; Peper & Harvey, 2008; Waderich et al, 2013).
Staying alert, scanning and reacting to the images on a computer screen or notifications from text messages, can become exhausting. in the past, we scanned the landscape, looking for information that will help us survive (predators, food sources, friend or foe) however today, we react to the changing visual stimuli on the screen. The computer display and notifications have become evolutionary traps since they evoke these previously adaptive response patterns that allowed us to survive.
The response patterns occur mostly without awareness until we experience discomfort. Fortunately, we can become aware of our body’s reactions with physiological monitoring which makes the invisible visible as shown in the figure below (Peper, Harvey & Faass, 2020).
Representative physiological patterns that occur when working at a computer, laptop, tablet or cellphone are unnecessary neck and shoulder tension, shallow rapid breathing, and an increase in heart rate during data entry. Even when the person is resting their hands on the keyboard, forearm muscle tension, breathing and heart rate increased.
Moreover, muscle tension in the neck and shoulder region also increased, even when those muscles were not needed for data entry task. Unfortunately, this unnecessary tension and shallow breathing contributes to exhaustion and discomfort (Peper, Harvey & Faass, 2020).
With biofeedback training, the person can learn to become aware and control these dysfunctional patterns and prevent discomfort (Peper & Gibney, 2006; Peper et, 2003). However, without access to biofeedback monitoring, assume that you respond similarly while working. Thus, to prevent discomfort and improve health and performance, implement the following.
- Practice breathing lower and slower to reduce sympathetic activation. Every few minutes remember to breathe slowly in and out through the nose. See the following blogs for more detailed instructions:
- Blink many times. Blink each time you click on a link, after typing a paragraph or after entering a few numbers.
- Get up, move, stretch and wiggle.
- Every few minutes do a small movement such as rotating your shoulders, dropping your hands to your lap.
- Every twenty minutes get up, stretch and walk around to reduce the chronic muscle tension.
- Install the free Stretch Break software on your computer or laptop to remind you to stretch… and then shows you how. Download free version from: https://stretchbreak.com/.
- Use small portable muscle biofeedback devices to learn awareness of the covert muscle tension and how to work without unnecessary muscle tension.

Breathing affects every cell of our body and should be the first intervention strategy to improve physical and mental well-being (Peper & Tibbetts, 1994). Breathing patterns are much more subtle than indicated by the respiratory function tests (spirometry, lung capacity, airway resistance, diffusing capacity and blood gas analysis) or commonly monitored in medicine and psychology (breathing rate, tidal volume, peak flow, oxygen saturation, end-tidal carbon dioxide) (Gibson, Loddenkemper, Sibille & Lundback, 2019).
When a person feels safe, healthy and peaceful, the breathing is effortless and the breath flows in and out of the nose without awareness. Functional and dysfunctional breathing patterns includes an assessment of the whole body pattern by which breathing occurs such as nose versus mouth breathing, alternation of nasal patency, the rate of air flow rate during inhalation and exhalation, the length of time during inhalation and exhalation, the post exhalation pause time. the pattern of transition between inhaling and exhaling, the location and timing of expansion in the truck, the range of diaphragmatic movement, and the subjective quality of breathing effort (Gilbert, 2019; Peper, Gilbert, Harvey & Lin, 2015; Nestor, 2020).
Breathing patterns affect sympathetic and parasympathetic nervous systems (Levin & Swoap, 2019). Inhaling tends to activate the sympathetic nervous system (fight/flight response) while exhaling activates the parasympathetic nervous system (rest and repair response) (Lehrer & Gevirtz, 2014). To observe how breathing affects your heart rate, monitor your pulse from either the radial artery in the wrist or the carotid artery in your neck as shown in Figure 1 and practice the following.
After sensing the baseline rate of your pulse, continue to feel your radial artery pulse in your wrist or at the carotid artery in your neck. Then inhale for the count of four hold for a moment and gently exhale for the count of 5 or 6. Repeat two or three times.
Most people observe that during inhalation, their heart rate increased (sympathetic activation for action) and during exhalation, the heart rate decreases (restoration during safety).
Nearly everyone who is anxious tends to breathe rapidly and shallowly or when stressed, unknowingly gasp or holds their breath–they may even freeze up and blank out (Peper et al, 2016). In addition, many people habitually breathe through their mouth instead of their nose and wake up tired with a dry mouth with bad breath. Mouth breathing combined with chest breathing in the absence of slower diaphragmatic breathing (the lower ribs and abdomen expand during inhalation and constrict during exhalation) is a risk factor for disorders such as irritable bowel syndrome, hypertension, tiredness, anxiety, panic attacks, asthma, dysmenorrhea, epilepsy, cold hands and feet, emphysema, and insomnia. Many of our clients who aware of their dysfunctional breathing patterns and are able to implement effortless breathing report significant reduction in symptoms (Chaitow, Bradley, & Gilbert, 2013; Peper, Mason, Huey, 2017; Peper & Cohen, 2017; Peper, Martinez Aranda, & Moss, 2015).
Breathing is usually overlooked as a first treatment strategy-it is not as glamorous as drugs, surgery or psychotherapy. Teaching breathing takes skill since practitioners needs to be experienced. Namely, they need to be able to demonstrate in action how to breathe effortlessly before teaching it to others. Although it seems unbelievable, a small change in our breathing pattern can have major physical, mental, and emotional effects as can be experienced in the following practice.
Begin by breathing normally and then exhale only 70% of the inhaled air, and inhale normally and again exhale only 70% of the inhaled air. With each exhalation exhale on 70% of the inhaled air. Continue this for 30 seconds. Stop and note how you feel.
Almost every reports that the 30 seconds feels like a minute and experience some of the following symptoms listed in table 1.
Table 1. Symptoms experienced after 30-45 seconds of sequentially exhaling 70% percent of the inhales air (Peper & MacHose, 1993).
Even though many therapists have long pointed out that breathing is essential, it is usually the forgotten ingredient. It is now being rediscovered in the age of the COVID-19 as respiratory health may reduce the risk of COVID-19.
Simply having very sick patients lie on their side or stomach can improve gas exchange. By lying on your side or prone, breathing is easier as the lung can expand more which appears to reduce the utilization of respirators and intubation (Long & Singh, 2020; Farkas, 2020). This side or prone breathing approach is thousands of years old.
One of the natural and health promoting breathing patterns to promote lung health is to breathe predominantly through the nose. The nose filters, warms, moisturizes and slows the airflow so that airway irritation is reduced. Nasal breathing also increases nitric oxide production that significantly increases oxygen absorption in the body. More importantly for dealing with COVID-19, nitric oxide, produced and released inside the nasal cavities and the lining of the blood vessels, acts as an anti-viral and is a secondary strategy to protect against viral infections (Mehta, Ashkar & Mossman, 2012). During inspiration through the nose, the nitric oxide helps dilate the airways in your lungs and blood vessels (McKeown, 2016).
To increase your health, breathe through your nose, yes, even at night (McKeown, 2020). As you practice this during the day be sure that the lower ribs and abdomen expand during inhalation and decrease in diameter during exhalation. It is breathing without effort although many people will report that it initially feels unnatural. Exhale to the count of about 5 or 6 and inhale (allow the air to flow in) to the count of 4 or 5. Mastering nasal breathing takes practice, practice and practice. See the following for more information.

COVID-19 can sometimes overwhelm young and old immune systems and in some cases can result in ‘Severe Acute Respiratory Syndrome’ pneumonia and death (CDC, 2020). The risk is greater for older people, and people with serious heart conditions (e.g., heart failure, coronary artery disease, or cardiomyopathies), cancers, obesity, Type 2 diabetes, COPD, chronic kidney disease, hypertension, smoking, immune suppression or other health issues (CDC, 2020a) as well as young people who vape or smoke and those with immunological defects in type I and II interferon production (Gaiha, Cheng, & Halpern-Felsher, 2020; van der Made, 2020). As we age the immune system deteriorates (immunosenescence) that reduces the response of the adaptive immune system that needs to respond to the virus infection (Aw, Silva & Palmer, 2007; Osttan, Monti, Gueresi, et al., 2016). On the other hand, for young people and children the risk is very low and similar for Covid-19 as for seasonal influenza A and B in rates for hospitalization, admission to the intensive care unit, and mechanical ventilator ( Song et al, 2020).
Severity of disease may depend upon initial dose of the virus
In a brilliant article, How does the coronavirus behave inside a patient? We’ve counted the viral spread across peoples; now we need to count it within people, assistant professor of medicine at Columbia University and cancer physician Siddhartha Mukherjee points out that severity of the disease may be related to the initial dose of the virus. Namely, if you receive a very small dose (not too many virus particles), they will infect you; however, the body can activate its immune response to cope with the infection. The low dose exposure act similar to vaccination. If on the other hand you are exposed to a very high dose then your body is overwhelmed with the infection and is unable to respond effectively. Think of a forest fire. A small fire can easily be suppressed since there is enough time to upgrade the fire-fighting resources; however, during a fire-storm with multiple fires occurring at the same time, the fire-fighting resources are overwhelmed and there is not enough time to recruit outside fire-fighting resources.
As Mukherjee points out this dose exposure relationship with illness severity has a long history. For example, before vaccinations for childhood illnesses were available, a child who became infected at the playground usually experienced a mild form of the disease. However, the child’s siblings who were infected at home develop a much more severe form of the disease.
The child infected in the playground most likely received a relatively small dose of the virus over a short time period (viral concentration in the air is low). On the other hand, the siblings who were infected at home by their infected brother or sister received a high concentration of the virus over an extended period which initially overwhelmed their immune system. Higher virus concentration is more likely during the winter and in well insulated/sealed houses where the air is recirculated without going through HEPA or UV filters to sterilize the air. When there is no fresh air to decrease or remove the virus concentration, the risk of severity of illness may be higher (Heid, 2020).
The risk of becoming sick with COVID-19 can only occur if you are exposed to the coronavirus and the competency of your immune system. This can be expressed in the following equation.This equation suggests two strategies to reduce risk: reduce coronavirus load/exposure and strengthen the immune system.
How to reduce the coronavirus load/dose of virus exposure
Assume that everyone is contagious even though they may appear healthy. Research suggests that people are already contagious before developing symptoms or are asymptomatic carriers who do not get sick and thereby unknowingly spread the virus (Furukawa, Brooks, Sobel, 2020). Dutch researchers have reported that, “The proportion of pre-symptomatic transmission was 48% for Singapore and 62% for Tianjin, China (Ganyani et al, 2020). Thus, the intervention to isolate people who have symptoms of COVID-19 (fever, dry cough, etc.) most likely will miss the asymptomatic carriers who may infect the community without awareness. Only if you have been tested, do you know if you been exposed or recovered from the virus. To reduce exposure to the virus, avoid the “Three C’s” — closed spaces with poor ventilation, crowded places and close contact—and do the following:
- Follow the public health guidelines:
- Social distance (physical distancing while continuing to offer social support)
- Wear a mask and gloves to reduce spreading the virus to others.
- Wash your hands with soap for at least 20 seconds.
- Avoid touching your face to prevent microorganisms and viruses to enter the body through mucosal surfaces of the nose mouth and eyes.
- Clean surfaces which could have been touched by other such as door bell, door knobs, packages.
- Avoid the person’s slipstream that may contain the droplets in the exhaled air. The purpose of social distancing is to have enough distance between you and another person so that the exhaled air of the other person would not reach you. The distance between people depends upon their activities and the direction of airflow.
In a simulation study, Professor Bert Blocken and his colleagues at KU Leuven and Eindhoven University of Technology reported that the plume of the exhaled air that potentially could contain the virus droplets could extend much more than 5 feet. It would depends upon the direction of the wind and whether the person is walking or jogging as show in Figure 1 (Blocken, 2020).
Figure 1. The plume of exhaled droplets that could contain the virus extends behind the person in their slipstream (photo from KU Leuven en TU Eindhoven).
The plume of exhaled droplets in the person’s slipstream may extend more than 15 feet while walking and more than 60 feet while jogging or bicycling. Thus. social distancing under these conditions is much more than 6 feet and it means avoiding their slipstream and staying much further away from the person.
- Increase fresh air to reduce virus concentration. The CDC recommends ventilation with 6 to 12 room air changes per hour for effective air disinfection (Nardell & Nathavitharana, 2020). By increasing the fresh outside air circulation, you dilute the virus concentration that may be shed by an infected asymptomatic or sick person (Qian & Zheng, 2018). Thus, if you are exposed to the virus, you may receive a lower dose and increase the probability that you experience a milder version of the disease. Almost all people who contract COVID-19 are exposed indoors to the virus. In the contact tracing study of 1245 confirmed cases in China, only a single outbreak of two people occurred in an outdoor environment (Qian et al, 2020). To increase fresh air (this assumes that outside air is not polluted), explore the following:
- Open the windows to allow cross ventilation through your house or work setting. One of the major reasons that the flu season spikes in the winter is that people congregate indoors to escape weather extremes. People keep their windows closed to conserve heat and reduce heating bill costs. Lack of fresh air circulation increases the viral density and risk of illness severity (Foster, 2014).
- Use an exhaust fans to ventilate a building. By continuously replacing the inside “stale” air with fresh outside air, the concentration of the virus in the air is reduced.
- Use High-efficiency particulate air (HEPA) air purifiers to filter the air within a room. These devices will filter out particles whose diameter is equal to 0.3 µ m. They will not totally filter out the virus; however, they will reduce it.
- Avoid buildings with recycled air unless the heating and air conditioning system (HAC) uses HEPA filters.
- Wear masks to protect other people and your community. The mask will reduce the shedding of the virus to others by people with COVID-19 or those who are asymptomatic carriers. This is superbly illustrated by Prather, Wang, & Schooley (2020) that not masking maximizes exposure, whereas universal masking results in the least exposure.
- Avoid long-term exposure to air pollution. People exposed to high levels of air pollution and fine particulate matter (PM2.5) are more at risk to develop chronic respiratory conditions and COVID-19 death rates. In the 2003 study of SARS, ecologic analysis conducted among 5 regions in China with 100 or more SARS cases showed that case fatality rate increased with the increment of air pollution index (Cui, Zhang, Froines, et al. , 2003). The higher the concentration of fine particulate matter (PM2.5), the higher the death rate (Conticini, Frediani, & Caro, 2020). As researchers, Xiao Wu, Rachel C. Nethery and colleagues (2020) from the Harvard T.H. Chan School of Public Health point out, “A small increase in long-term exposure to PM2.5 leads to a large increase in COVID-19 death rate, with the magnitude of increase 20 times that observed for PM2.5 and all cause mortality. The study results underscore the importance of continuing to enforce existing air pollution regulations to protect human health both during and after the COVID-19 crisis.“
- Breathe only through your nose. The nose filters, warms, moisturizes and slows the airflow so that airway irritation is reduced. Nasal breathing increases nitric oxide production that significantly increases oxygen absorption in the body. During inspiration through the nose the nitric oxide helps dilate the airways in your lungs and blood vessels (McKeown, 2016). More importantly for dealing with COVID-19, Nitric Oxide, produced and released inside the nasal cavities and the lining of the blood vessels, acts as an antiviral and a secondary strategy to protect against viral infections (Mehta, Ashkar & Mossman, 2012).
How to strengthen your immune system to fight the virus
The immune system is dynamic and many factors as well as individual differences affect its ability to fight the virus. It is possible that a 40 year-old person may have an immune systems that functions as a 70 year old, while some 70 year-olds have an immune system that function as a 40 year-old. Factors that contribute to immune competence include genetics, aging, previous virus exposure, and lifestyle (Lawton, 2020).
It is estimated that 70-80% mortality caused by Covid-19 occurred in people with comorbidity who are: over 65, male, lower socioeconomic status (SES), non white, overweight/obesity, cardiovascular heart disease, and immunocompromised. Although children comprised only a small percentage of the seriously ill patients, 83% of those children in the intensive care units had comorbidities and 60% were obese. The majority of contributing factors to comorbidities and obesity are the result of economic inequality and life style patterns such as the Western inflammatory diet (Shekerdemian et al, 2020; Zachariah, 2020; Pollan, 2020).
By taking charge of your lifestyle habits through an integrated approach, you may be able to strengthen your immune system (Alschuler et al, 2020; Lawton, 2020). The following tables, adapted from the published articles by Lawton (2020), Alschuler et al, (2020) and Jaffe (2020), list factors that support or decrease the immune system.
Factors that decrease immune competence
Factors that support immune competence
Phytochemicals and vitamins that support immune competence
An ounce of prevention is worth a pound of cure. Thus, to reduce the risk of covid-19 disease severity, implement strategies to reduce viral dosage exposure and strengthen the immune system. Many of these factors are within our control. Thus, increase fresh air circulation, reduce stress, decrease foods that tend to increase inflammation (the industrialized western diet that significant contributes to the development of chronic disease), and increase foods, vitamins and nutrients that support immune competence.
These factors have been superbly summarized by the World Health Organization Director General Dr. Tedros Adhanom in his presentation, Practical tips how to keep yourself safe.
