Exploiting evolutionary traps: Netflix’s new movie, The Social Dilemma

Addicted to the screen (Photo from the Netflix’s docudrama, The Social Dilemma)

Apple founder Steve Jobs didn’t let his kids use the iPad, or really any product their dad invented, As Steve Jobs stated, “They haven’t used it,” “We limit how much technology our kids use at home.” (Bilton, 2014).

In 2007, Bill Gates, the former CEO of Microsoft, implemented a cap on screen time when his daughter started developing an unhealthy attachment to a video game. He also didn’t let his kids get cell phones until they turned 14 (Akhtar & Ward, 2020).

What is it that these two titans of the tech revolution and the many Silicon Valley insiders know and discuss in the  Netflix docudrama, The Social Dilemma?

They recognized the harm that occurs when monetary incentives are the singular driver to optimize the hardware (the look and feel of the cellphone)  and much more important  the software algorithms to capture the attention of the user.  It is interesting that there are only two industries that label their customers as users, illegal drugs and software (Kalsim 2020).

The longer a user is captured by the screen, the more the user responds to notifications, the more the user clicks to other sites, the more money the corporation earns from its advertisers. The algorithms continuously optimize what the user sees and hears so that they stay captured. Thus, the algorithms are designed to exploit the evolutionary response patterns that allowed us to survive and thrive. Evolutionary traps occur when adaptive behaviors that were once successful become maladaptive or even harmful. When this occurs, cues that were protective or beneficial can lead to reduced health and fitness (Peper, Harvey & Faass 2020).

Companies exploit evolutionary traps for the purpose of improving profits. This potentially constitutes a major health risk for humanity.  As quoted from the The Social Dilemma, “Your attention is the product that is being sold to advertisers”

Google, Facebook, Twitter, Instagram, Pinterest, and others are designed to be highly addictive and incorporate some of the following evolutionary traps (Peper, Harvey & Faass, 2020):

  • We are wired to see artificial images and to hear reproduced sounds as real. The brain does not discriminate between actual and visual-auditory images that are artificial, which explains one aspect of our attraction to our phones, to binge-watching, and to gaming.
  • We are wired to react to any stimuli that suggests potential danger or the presence of game animals. Whether the stimuli is auditory, visual, tactile, or kinesthetic, it triggers excessive arousal. This makes us vulnerable to screen addiction, because our biology compels us to respond.
  • We are wired to attend to social information about power within our group, a major factor in social media addiction.

If you concerned about false news, political polarization, radicalization, increased anxiety, depression, suicides  and mental health in people, watch Netflix, The Social Dilemma and the powerful presentation by Sacha Baron Cohen’s superb presentation, Never is Now, the 2019 Anti-Defamation League Leadership Award.

What makes this film so powerful is that it is told by the same people who were the designers, developers, and programmers for the different social media companies.

Ways to reduce TechStress

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.

authors Erik and Rick1

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.

Why do I have neck and shoulder discomfort at the computer?

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.shoulder pain

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.

EMGFigure 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.

Resolve Eyestrain and Screen Fatigue

eyes
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.palming
    • 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.

neck

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).

biofeedback

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.

Finally, for a comprehensive overview based on an evolutionary perspective that explains why TechStress develops, why digital addiction occurs. and what can be done to prevent discomfort and improve health and performance, see our new book by Erik Peper, Richard Harvey and Nancy Faass, Tech Stress-How Technology is Hijack our Lives, Strategies for Coping and Pragmatic Ergonomics.

Do nose breathing FIRST in the age of COVID-19

nose breathingBreathing 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.radial and carotid arteru

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.

Capture

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.

Reduce initial dose of the virus and optimize your immune system

Erik Peper and Richard Harvey

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, 2020van 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.Risk ratioThis 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 contactand do the following:

  1. 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.
  1. 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).

Slipstream

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. 

  1. 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.
    • masks without header
  1. 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.
  2. 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.

Conclusion

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.

Can changing your breathing pattern reduce coronavirus exposure?

sneeze

This blog is based upon our breathing  research that began in the 1990s, This  research helped identify dysfunctional breathing patterns that could contribute to illness. We developed coaching/teaching strategies with biofeedback to optimize breathing patterns, improve health and performance (Peper and Tibbetts, 1994; Peper, Martinez Aranda and Moss, 2015; Peper, Mason, and Huey, 2017).

For example, people with asthma were taught to reduce their reactivity to cigarette smoke and other airborne irritants (Peper and Tibbitts, 1992Peper and Tibbetts, 2003).  The smoke of cigarettes or vaping spreads out as the person exhales. If the person was infected, the smoke could represent the cloud of viruses that the other people would inhale as is shown in Figure 1.vaping

Figure 1. Vaping by young people in Riga, Latvia (photo by Erik Peper).

To learn how to breathe differently, the participants  first learned effortless slow diaphragmatic breathing. Then were taught that the moment they would become aware of an airborne irritant such as cigarette smoke, they would hold their breath and relax their body and move away from the source of the polluted air while exhaling very slowly through their nose. When the air was clearer they would inhale and continue effortless diaphragmatically breathing (Peper and Tibbetts, 1994).  From this research we propose that people may reduce exposure to the coronavirus by changing their breathing pattern; however, the first step is prevention by following the recommended public health guidelines.

  • Social distancing (physical distancing while continuing to offer social support)
  • Washing your hands with soap for at least 20 seconds
  • Not touching your face
  • Cleaning surfaces which could have been touched by other such as door bell, door knobs, packages.
  • Wear a mask 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.

Reduce your exposure to the virus when near other people by changing your breathing pattern 

Normally when startled or surprised, we tend to gasp and inhale air rapidly. When someone sneezes, coughs or exhales near you, we often respond with a slight gasp and inhale their droplets. To reduce inhaling their droplets (which may contain the coronavirus virus), implement the following:

  • When a person is getting too close
    • Hold your breath with your mouth closed and relax your shoulders (just pause your breathing) as you move away from the person.
    • Gently exhale through your nose (do not inhale before exhaling)-just exhale how little or much air you have
    • When far enough away, gently inhale through your nose.
    • Remember to relax and feel your shoulders drop when holding your breath.  It will last for only a few seconds as you move away from the person.  Exhale before inhaling through your nose.
  • When a person coughs or sneezes
    • Hold your breath, rotate you head away  from the person and move away from them while exhaling though your nose.
    • If you think the droplets of the sneeze or cough have landed on you or your clothing, go home, disrobe outside your house, and put your clothing into the washing machine. Take a shower and wash yourself with soap.
  • When passing a person ahead of you or who is approaching you
    • Inhale before they are too close and exhale through your nose as you are passing them.
    • After you are more than 6 feet away gently inhale through your nose.
  • When talking to people outside
    • Stand so that the breeze/wind hits both people from the same side so that the exhaled droplets are blown away from both of you (down wind).

These  breathing skills seem so simple; however, in our experience with people with asthma and other symptoms, it took practice, practice, and practice to change their automatic breathing patterns. The new pattern is pause (stop) the breath and then exhale through your nose. Remember, this breathing pattern is not forced and with practice it will occur effortlessly.

The following blogs offer instructions for mastering effortless diaphragmatic breathing.

Numerous people report that working at the computer at home is more tiring than working in the office.  Although there are obvious advantages to working at home, there are also disadvantages (e.g., no space to work, challenging ergonomics, no escape from the family, lack of nonverbal cues used to communicate, less informal sharing at the water cooler, increased multitasking by working and having to take care of the children).

A major challenge is having a comfortable work space in your home.  This may mean finding a place to put the computer, keyboard and screen.  For some it is the kitchen table, desk in the corner of the bedroom, or coffee table while other it is in a totally separate room.

Incorrect ergonomic arrangement and stressed work style often increases neck, shoulder discomfort and aggravates eye strain and tiredness. Regardless how your digital work space is organized, implement the following life and work style suggestions and ergonomics recommendations to promote health.

LIFE AND WORK STYLE SUGGESTIONS

Take many, many, many breaks.  Movement breaks will reduce the covert static tension that builds up as we sit in static positions and work at the computer.

  • Every few minutes take a small break such as stand up and wiggle or role your shoulders. When performing the movements, stop looking at the screen and look around the room or out the window.
  • Every 30 minutes get up walk around for and move your body. Use timers to notify you every 30 minutes to take a break (e.g., cellphone alarms or personal digital assistants such as Hey Google, Siri, or Alexa).

Improve vision.

  • Take vision breaks to reduce eye fatigue.
    • Every few minutes look away from the screen and into the far distance and blink. If at all possible look outside at green plants which relaxes the near vision induced tension.
    • Blink and blink again. When working at the computer we reduce our blinking rate. Thus, blink each time you click on a new link, finishing entering a column of numbers, etc.
    • Close your eyes by letting the eye lids drop down as you also relax your jaw. Imagine a hook on top of your head which is pulling your head upward and at the same time drop your shoulders.
  • Reduce glare and bright backgrounds
    • Arrange your computer screen at 90 degrees to the brightest light source.
    • Have a darker background behind you when participating in video conferencing (e.g., Zoom, Skype, GoToMeeting, WhatsApp, FaceTime). Your face will be visible.

Regenerate

  • When stressed remember to breathe. As you inhale let your stomach expand as you exhale let the air flow out slowly.
  • Stop watching and listening to the negative news (check the news no more than once a day). Watch positive and humorous movies.
  • Get fresh air, go for a walk, and be in the sun
  • Reconnect with friends and share positive experiences.
  • Remind yourself, that this too shall pass.

ERGONOMIC RECOMMENDATIONS: MAKE THE WORLD YOURS

Good ergonomics means adapting the equipment and environment to you and not the other way around. Optimizes the arrangement of the chair, desk, keyboard, mouse, camera, screen and yourself as shown in Figure 1.

Arrange the laptop

The laptop is challenging because if your hands are at the right height for data entry on the keyboard, then you must look down to see the screen.  If the screen at the right height, then you have to raise your hands to reach the keyboard. There are two solutions for this challenge.

  1. Use an external keyboard and mouse, then raise the laptop so that the top of the screen is at eye level. Use a laptop stand or a stack of books to raise the lap top.
  2. Use an external monitor for display, then use the laptop as your keyboard.

If these solutions are not possible, take many, many, many breaks to reduce the neck and shoulder stress.

Arrange the computer workstation

  1. Adjust the chair so that your forearms can rest on the table without raising your shoulders. This may mean sitting on a pillow. If the chair is then too high and your legs dangle, create a foot stool on which you can rest your feet.
  2. Adjust the monitor so that the top of the screen is at eye level. If the monitor is too low, raise it by putting some books underneath it.
  3. If possible, alternate standing and sitting while working.

Coronavirus risk in context: How worried should you be?

The coronavirus which causes coronavirus disease 2019 (COVID-19) appears to be a highly contagious disease. Some older people and those who are immune compromised are more at risk.  The highest risk are for older people who already have cardiovascular, diabetes, respiratory disease, and hypertension. In addition, older men over 65 years are much more at risk; however, many are smokers who have a compromised pulmonary system. Previous meta analysis showed that smoking was consistently associated with higher risk of hospital admissions after influenza infection. Nevertheless, it is reasonable to assume that over time all most all of us will become exposed to the virus, a few will get very sick, and even fewer will die.

The preliminary data suggests that most people who become infected may not even know they are infectious. Make the assumption that everyone could be contagious unless tested for the virus or antibodies to the virus since people appear to be infectious for the first four days before experiencing symptoms.

corona virus infection

The absolute risk that one would die of this disease is low although if you do become very sick it is more dangerous than the normal flu; however, the fear of this disease may be out of proportion compared to other health risks. For detailed analysis and graphic summaries see the updated research reports on the Coronavirus disease (COVID-19) by Our World in Data and Information is beautiful. These reports make data and research on the world’s largest problems understandable and accessible.

It is worthwhile to look at the absolute risk of COVID-19.  To read that more than 332,000 people world wide have died in the last five months is terrifying especially with the increasing death rate in Europe and New York; however, it needs to be understood in context of the size of the population.  The epicenter of this disease was Wuhan and Hubei Provence, China with a total population of about 60 million people.  Each year about 427,200 people die in the Wuhan and Hubei Province (the annual death rate in China is 7.12 deaths per 1000 people). Without this new viral disease, about 71,200 people would have died during the same two month period.  The question that has not been discussed is how much did the total death rate increase.  Would it be possible that some of the people who died would have died of other natural causes such as the flu?

The World Health Organization (WHO) and governments around the world should be lauded for their attempt to reduce the spread of the virus. On March 6, 2020, the United States Congress allocated $8. billion dollars to fight and prevent the spread of COVID-19. 

This funding will only partially prevent the spread of the virus because some people have no choice but to go to work when they are sick–they do not receive paid sick leave! This is true for about 30 percent of the American workers who have no coverage at work or the millions of self-employed workers (e.g. gig/freelance workers, waiters, cashiers, drivers, nannies, house cleaners).

To reduce the risk of the spreading COVID-19, anyone who feels sick or thinks they have been exposed, should receive paid sick leave so that they can stay home and self-isolate. The paid sick leave should be Federally funded and provide basic income for those whose income would be lost if they did not work.  Although it is possible that a few people will cheat and take the paid sick leave when they are well, this is worth the risk to keep the rest of population healthy. To provide possible relief, at the moment the House and Senate are working on a greater than $2 trillion dollar stimulus package. 

Personal and government responses to health risks are not always rational. 

Funding for health and illness prevention is driven by politics. For example, gun violence results in more than 100,000 people being injured each year and more than 36,000 killed—an average of 100 per day. Gun violence is a much more virulent disease than COVID-19 and more than 1.7 million Americans have died from firearms since 1968.

The Federal Government response to this gun violence epidemic has been minimal. For the first time since 1996 did the 2020 federal budget include $25 million funding for the CDC and NIH to research reducing gun-related deaths and injuries.

It is clear that the government response does not always focuses its resources on what would reduce injury and death rates the most.  Look at the difference in the national response to COVID-19 virus that has killed more than 120,000 people in the USA ($8.5 billion for the initial response and then $2 trillion stimulus package) as compared gun violence that kills 36,000 people a year in the USA ($25 million funding to study the causes of gun violence).

Be realistic about the actual risk of COVID-19 without succumbing to fear.

COVID-19 is a pandemic and I expect that 30% to 70% of us will be infected this year.  Hopefully, in the next 18 months an effective vaccine will be developed.  In the mean time, there is no known treatment, thus optimize health and reduce the exposure to the coronavirus.

To make sense of the danger of COVID-19, look at it in context to the flu. The risk is the greatest for people with co-morbidity (obesity, diabetes,  emphysema, immune suppressed illnesses, and people who smoke and vape). While the risk for young people and children is no different for being infected with Covid-19 or influensa A and B in hospitalization rates, intensive care unit admission rates, and mechanical ventilator (Song et al. 2020). Depending upon the severity the  flu, 9,000,000 to 45,000,000 people get sick from flu and between 12,000 to 61,000 die from its complications as shown below in Figure 1.
