Healing from paralysis-Music (toning) to activate health
Posted: November 22, 2021 Filed under: behavior, Breathing/respiration, emotions, healing, health, mindfulness, stress management, Uncategorized | Tags: chakra, chanting, music therapy, paralysis, quadriplegia, singing, Toning 8 CommentsMadhu Anziani and Erik Peper
In April 2009, Madhu Anziani, just one month prior to graduation from San Francisco State University with a degree in Jazz/World music performance, fell two stories and broke C5 and C7 vertebras. He became a quadriplegic (tretraplegia) and could not breathe, talk, move his arms and legs and was incontinent. He also could not remember anything about the accident because of retrograde amnesia. Even though he was paralyzed and the medical staff suggested that he focussed on how to live well as a quadriplegic, he transcended his paralysis and the prognosis and is now a well-known vocal looping arts and ceremonial song leader/composer.
His recovery against all odds provides hope that growth and healing is possible when the mind and spirit focus on possibilities and not on limitations. Alongside physical thereapy he utilized energy healing and toning/sound vibrations to recover mobility. Toning, the vocalization of an elonggated monotonous vowel sound susteained for a number of minutes tends to vibrate specific areas in the body where the chakras are located (Crowe & Scovel, 1996; Goldman, 2017). Toning compared to mindfulness meditation reduces intrusive thoughts and mind wandering. It also increases body vibration sensations and heart rate variability much more than mindfulness practice (Peper et al, 2019). The body vibrations induced by toning and music could be one of the mechanisms by which recovery can occur at an accelerated rate as it allows the person’s passive awareness and sustained attention to feel the paralyzed body and yet be relaxed in the present without judgement.
Watch Madhu’s inspirational presentation as part of the Holistic Health Lecture Series by the Institute for Holistic Health Studies, San Francisco State University. In this presentation, he describes the process of recovery and guides the viewer through toning practices to evoke quieting of mind, bliss within the heart, and a healing state of being.
For an additional discussion and guided practice in toning, see the blog, Toning quiets the mind and increases HRV more quickly than mindfulness practice.
Madu Anziani is a sound healer who endured being a tetraplegic (paralysis affecting all four
limbs) and used sound and energy healing to recover mobility. He is a SFSU graduate and most
well-known as a vocal looping artist and ceremonial song leader/composer.

Our evolutionary traps with technology
Maintaining and optimizing health at the computer means re-envisioning our relationship with technology—and reclaiming health, happiness, and sanity in a plugged-in world. We have the ability to control everything from our mobile phones without needing to get up from our seat. Work, social life and online learning all involve the mobile phone or some type of smart devices.
A convenient little device that is supposed to simplify our lives has actually trapped us into a vicious cycle of relying on it for every single thing we must do. We spend most of our day being exposed to digital displays on our smartphones, computers, gaming consoles, and other digital devices, immersing ourselves in the content we are viewing. From work related emails or tasks, to spending our free time looking at the screen for texting, playing games, and updating social media sites on a play-by-play of what we are eating, wearing, and doing. We click on one hyperlink after the other and create a vicious cycle trapped for hours until we realize we need to move. We are unaware how much time has frittered away without actually doing anything productive and then, we realize we have wasted another day. Below are some recent estimates of ‘daily active user’ minutes per day that uses a screen.
- Facebook about an hour per day
- Instagram just under an hour per day
- Texting about 45 minutes per day
- Internet browsing, about 45 minutes per day
- Snapchat, about 30 minutes per day
- Twitter, about 25 minutes per day
Adolescents and college students interact with media for over 40 hours per week, or around 6 hours per day. That is a lot of hours spent on staring at the screen, which it is almost impossible not to be distracted by the digital screen. In time, we rehearse a variety of physical body postures as well as a variety of cognitive and behavioral states that impact our physical, mental, emotional, and social health. The powerful audiovisual formats override our desires to do something different, that some of us become enslaved to streaming videos, playing virtual games, or texting. We then tell ourselves that the task that needs to be done, will be finished later. That later becomes never by the end of the day, since the ongoing visual and auditory notifications from our apps interrupt and/or capture our attention. This difficulty to turn away from visual or auditory stimuli roots in our survival instincts.
Each time visual or auditory stimuli occur, we automatically check it out and see if it is a friend or foe, safety or danger. It is such an automatic response that we are unaware are reacting. The good news is that we all have experienced this compelling effect. Even when we are waiting for a response and the notifications has not arrived, we may anticipate or project that there may be new information on our social media accounts, and sometimes we become disappointed when the interval between notification is long. As one student said, “Don’t worry, they’ll respond. It’s only been 30 seconds”. Anticipating responses from the media can interrupt what we are otherwise doing. Rather than finishing our work or task, we continuously check for updates on social media, even though we probably know that there are no new important messages to which we would have to respond right away.
Unfortunately, some forms of social media interactions also lead to a form of social isolation, loneliness–sometimes called phoneliness (Christodoulou, G., Majmundar, A., Chou, C-P, & Pentz, M.A., 2020; Kardaras, 2017). Digital content requires the individual to respond to the digital stimuli, without being aware of the many verbal and nonverbal communication cues (facial expressions, gestures, tone of voice, eye contact, body language, posture, touch, etc.) that are part of social communication (Remland, 2016). It is no wonder that more and more adolescents experience anxiety, depression, loneliness, and attention deficit disorders with a constant ‘digital diet’ that some have suggested that include not only media, but junk food as well.
In my class survey of 99 college students, 85% reported experiencing anxiety, 48% neck and should tension, and 41% abdominal discomfort.
We are not saying to avoid the beneficial parts of the digital age. Instead, it should be used in moderation and to be aware of how some material and digital platforms prey upon our evolutionary survival mechanisms. Unfortunately, most people -especially children- have not evolved skills to counter the negative impacts of some types of media exposure. Parental control and societal policies may be needed to mitigate the damage and enhance the benefits of the digital age.
Zoom Fatigue- How to reduce it and configure your brain for better learning
Zoom became the preferred platform for academic teaching and learning for synchronous education during the pandemic. Thus, students and faculty have been sitting and looking at the screen for hours end. While looking at the screen, the viewers were often distracted by events in their environment, notifications from their mobile phones, social media triggers, and emails; which promoted multitasking (Solis, 2019). These digital distractions cause people to respond to twice as many devices with half of our attention- a process labeled semi-tasking’ -meaning getting twice as much done and half as well.
We now check our phones an average of 96 times a day – that is once every 10 minutes and an increase of 20% as compared to two years ago (Asurion Research, 2019). Those who do media multitasking such as texting while doing a task perform significantly worse on memory tasks than those who are not multitasking (Madore et al., 2020). Multitasking is negatively correlated with school performance (Giunchiglia et al, 2018). The best way to reduce multitasking is to turn off all notifications (e.g., email, texts, and social media) and let people know that you will look at the notifications and then respond in a predetermined time, so that you will not be interrupted while working or studying.
When students from San Francisco State University in the United States chose to implement a behavior change to monitor mobile phone and media use and reduce the addictive behavior during a five-week self-healing project, many reported a significant improvement of health and performance. For example one student reported that when she reduced her mobile phone use, her stress level equally decreased as shown in Fig 1 (Peper et al, 2021).
Figure 1. Example of student changing mobile phone use and corresponding decrease in subjective stress level. Reproduced by permission from Peper et al. (2021).
During this class project, many students observed that the continuous responding to notifications and social media affected their health and productivity. As one student reported,
The discovery of the time I wasted giving into distractions was increasing my anxiety, increasing my depression and making me feel completely inadequate. In the five-week period, I cut my cell phone usage by over half, from 32.5 hours to exactly 15 hours and used some of the time to do an early morning run in the park. Rediscovering this time makes me feel like my possibilities are endless. I can go to work full time, take online night courses reaching towards my goal of a higher degree, plus complete all my homework, take care of the house and chores, cook all my meals, and add reading a book for fun! –22-year-old College Student
Numerous students reported that it was much easier to be distracted and multitask, check social media accounts or respond to emails and texts than during face-to-face classroom sessions as illustrated by two student comments from San Francisco State University.
“Now that we are forced to stay at home, it’s hard to find time by myself, for myself, time to study, and or time to get away. It’s easy to get distracted and go a bit stir-crazy.”
“I find that online learning is more difficult for me because it’s harder for me to stay concentrated all day just looking at the screen.”
Students often reported that they had more difficulty remembering the material presented during synchronous presentations. Most likely, the passivity while watching Zoom presentations affected the encoding and consolidation of new material into retrievable long-term memory. The presented material was rapidly forgotten when the next screen image or advertisement appeared and competed with the course instructor for the student’s attention. We hypothesize that the many hours of watching TV and streaming videos have conditioned people to sit and take in information passively, while discouraging them to respond or initiate action (Mander, 1978; Mărchidan, 2019).
To reduce the deleterious impact of media use, China has placed time limits on cellphone use, gaming, and social media use for children. On February 2021 Chinese children were banned from taking their mobile phones into school, on August 2021 Children under 18 were banned from playing video games during the week and their play was restricted to just one hour on Fridays, weekends and holidays, and beginning on September 20, 2021 children under 14 who have been authenticated using their real name can access Douyin, the Chinese version of Tik Tok, for maximum of 40 minutes a day between the hours of 6:00 and 22:00.
Ways to avoid Zoom
Say goodnight to your phone
It is common for people to use their mobile phone before going to bed, and then end up having difficult falling asleep. The screen emits blue light that sends a signal to your brain that says it is daytime instead of night. This causes your body to suppress the production of the melatonin hormone, which tells your body that it is time to sleep. Reading or watching content also contributes, since it stimulates your mind and emotions and thereby promote wakefulness (Bravo, 2020). Implement sleep hygiene and stop using your phone or watching screens 30-minutes before going to bed for a better night’s sleep.
Maintaining a healthy vision
We increase near visual stress and the risk of developing myopia when we predominantly look at nearby surfaces. We do not realize that eyes muscles can only relax when looking at the far distance. For young children, the constant near vision remodels the shape of eye and the child will likely develop near sightedness. The solutions are remarkably simple. Respect your evolutionary background and allow your eyes to spontaneously alternate between looking at near and far objects while being upright (Schneider, 2016; Peper, 2021; Peper, Harvey & Faass, 2020).
Interrupt sitting disease
We sit for the majority of the day while looking at screens that is a significant risk factor for diabetes, cardiovascular disease, depression and anxiety (Matthews et al., 2012; Smith et al., 2020). Interrupt sitting by getting up every 30 minutes and do a few stretches. You will tend to feel less sleepy, less discomfort and more productive. As one of our participants reported that when he got up, moved and exercised every 30 minutes at the end of the day he felt less tired. As he stated, “There is life after five”, which meant he had energy to do other activities after working at the computer the whole day. While working time flies and it is challenging to get up every 30 minutes. Thus, install a free app on your computer that reminds you to get up and move such as StretchBreak (www.stretchbreak.com).
Use slouching as a cue to change
Posture affects thoughts and emotions as well as, vice versa. When stressed or worried (e.g., school performance, job security, family conflict, undefined symptoms, or financial insecurity), our bodies tend to respond by slightly collapsing and shifting into a protective position. When we collapse/slouch, we are more at risk to:
- Feel helpless (Riskind & Gotay, 1982).
- Feel powerless (Westfeld & Beresford, 1982; Cuddy, 2012).
- Recall and being more captured by negative memories (Peper, Lin, Harvey, & Perez, 2017; Tsai, Peper, & Lin, 2016),
- Experience cognitive difficulty (Peper, Harvey, Mason, & Lin, 2018).
When stressed, anxious or depressed, it is challenging to change. The negative feelings, thoughts and worries continue to undermine the practice of reframing the experience more positively. Our recent study found that a simple technique, that integrates posture with breathing and reframing, rapidly reduces anxiety, stress, and negative self-talk (Peper, Harvey, Hamiel, 2019). When you are captured by helpless defeated thoughts and slouch, use the thought or posture as the trigger to take change. The moment you are aware of the thoughts or slouched posture, sit up straight, look up, take a slow large diaphragmatic breath and only then think about reframing the problem positively (Peper, Harvey, Hamiel, 2019).
When we are upright and look up, we are more likely to:
- Have more energy (Peper & Lin, 2012).
- Feel stronger (Peper, Booiman, Lin, & Harvey, 2016).
- Find it easier to do cognitive activity (Peper, Harvey, Mason, & Lin, 2018).
- Feel more confident and empowered (Cuddy, 2012).
- Recall more positive autobiographical memories (Michalak, Mischnat,& Teismann, 2014).
The challenge is that we are usually unaware we have begun to slouch. A very useful solution is to use a posture feedback device to remind us, such as the UpRight Go (https://www.uprightpose.com/). This simple device and app signals you when you slouch. The device attaches to your neck and connects with blue tooth to your cellphone. After calibrating, it provides vibrational feedback on your neck each time you slouch. When participants use the vibration feedback to become aware of what is going on and interrupt their slouch by stretching and sitting up, they report a significant decrease in symptoms and an increase in productivity. As one student reported: “Having immediate feedback on my posture helped me to be more aware of my body and helped me to link my posture to my emotions. Before using the tracker, doing this was very difficult for me. It not only helped my posture but my awareness of my mental state as well.”

Rest Rusts: Increase dynamic movement to improve health
Posted: September 16, 2021 Filed under: behavior, computer, ergonomics, Evolutionary perspective, Exercise/movement, health, laptops, Neck and shoulder discomfort, Pain/discomfort, posture, screen fatigue, zoom fatigue | Tags: dynamic movement, static postures 2 CommentsIn hunting and gathering cultures, alternating movement patterns was part of living and essential for health. This shift from dynamic movement to static or awkward positions is illustrated in Figure 1.
Figure 1. The shift from dynamic movement to immobility and near vision as illustrated by the Hadzabe men in Tanzania returning from a hunt to our modern immobilized work and pleasure positions (Reproduced by permission from Peper, Harvey & Faass, 2020).
Dynamic movement promotes blood and lymph circulation and reduces static pressures. At present times our work and leisure activities increase immobility and static positions as we predominantly have shifted to a sitting immobilized position. This significantly increases musculoskeletal discomfort, cardiovascular disease, diabetes etc. The importance of movement as a factor to enhance health is illustrated in the recent findings of 2110 middle aged participants who were followed up for ten years. Those who took approximately 7000 steps per day or more experienced significantly lower mortality rates compared with participants taking fewer than 7000 steps per day (Paluch et al., 2021). Just having the head forward while looking at the cellphone significantly increases the forces on the muscles holding the head up as illustrated in Figure 2.
Figure 2. The head-forward position puts as much as sixty pounds of pressure on the neck muscles and spine (reproduced by permission from Dr. Kenneth Hansaraj, 2014).
For background and recommendations on what how to reduce static positions, look at our book, TechStress-How technology is hijacking our lives, strategies for coping and pragmatic ergonomics. and the superb article, Static postures are harmful – dynamic postures at work are key to musculoskeletal health, published by the European Agency for Safety and Health at Work (EU-OSHA, Sept 16, 2021) and reproduced below.
Static postures are harmful – dynamic postures at work are key to musculoskeletal health
Our bodies are built for movement – it’s a central part of maintaining a healthy musculoskeletal system and the less we move, the more chance we have of developing health issues including musculoskeletal disorders (MSDs), type 2 diabetes, cardiovascular disease, cancer and more. However, the negative effects of sedentary work can be mitigated by paying attention to the postures we adopt when we work.
Whether workers are standing or seated while working, maintaining a good ergonomic posture is essential when it comes to preventing MSDs. Poor or awkward postures put unnecessary strain on the musculoskeletal system and, over time, can cause the deterioration of muscle fibres and joints.
Poor or awkward postures include those which involve parts of the body not being in their natural position. More muscular effort is needed to maintain unnatural postures, which increases the energy used by the body and can cause fatigue, discomfort and pain. Unnatural postures also put strain on tendons, ligaments and nerves, which increases the risk of injury. For example, the risk of neck pain increases when the neck is rotated more than 45 degrees for more than 25% of the working day.
These postures, including slouching, rotation of the forearms, or prolonged periods of sitting or standing in the same spot, can cause pain in the lower back and upper limbs. The risk increases when combined with repetitive work, static muscle load, or the need to apply force or reach. And even natural or good postures maintained for any length of time become uncomfortable and eventually painful. Everyone has experienced stiffness after being in the same position for any length of time.
What do we mean by ‘good posture’?
For workers, especially those in sedentary jobs such as office work, factory work or driving, it is important to recognise and adopt good postures. A good posture should be comfortable and allow the joints to be naturally aligned. The segments of our body can be divided into three cross-sectional anatomical planes: the sagittal plane, which concerns bending forwards and backwards; the frontal plane, which concerns bending sideways; and finally the transverse plane, which refers to rotation or twisting of the body parts. A good posture is one that ensures that all three of these planes are set at neutral positions as much as possible, in that the worker is not leaning backwards, forwards or to any particular side, and their limbs and torso are not rotated or twisted. Adopting neutral postures will help to lessen the strain on the worker’s muscles, tendons and skeletal system, and reduces the risk of them causing or aggravating an MSD.
In practice, workers can consider the following checklist to ensure that they’re standing or sitting in a neutral position:
- Keep the neck vertical and the back in an upright position.
- Ensure the elbows are below the chest and avoid having to reach excessively.
- Keep the shoulders relaxed and use back and arm rests where possible and ensure that they are adjusted to the size and shape of the worker.
- Avoid rotating the forearms or excessively moving the wrists.
- Ensure that any work tools can be held comfortably, and that clothing doesn’t restrain or prevent movement.
- Allow room to comfortably move the legs and feet and avoid frequent kneeling or squatting.
- Ensure that long periods of standing or sitting in the same posture can be broken up.
Employers can assist workers in adopting good postures by communicating checklists such as this one, and by promoting physical activity where possible, encouraging the fair rotation of tasks between employees to avoid them consistently making repetitive movements, and ensuring that workers have the capacity to take regular breaks.
Why our next posture is the best posture
However, maintaining a good posture at all times is not enough to reduce the risk of MSDs, and can even be harmful. Static postures, even if ergonomic, are still a risk factor if over-used. Our body requires movement and variety, which is why the best approach is to use a variety of ergonomic postures in rotation, breaking up long periods of static working with stretching, exercise, and movement. This is known as adopting ‘dynamic positions’.
It is important not only for workers who spend much of their day seated, but also for workers who primarily stand – such as factory workers in assembly lines. In both cases, sitting and standing are not opposites. The opposite of both is movement. Changing postures between sitting and standing is not sufficient for any worker – the working environment must still offer ways of varying their postures and incorporating movement into their daily working routines. What’s more, if standing work cannot be avoided, workers do not need lots of space in order to adopt dynamic positions in a healthy way. Blood flow propulsion mechanisms can still work correctly even if the worker is only moving around in one square metre. However it is still the case that they should have a break after 30 minutes of standing.
Work should therefore not only facilitate good postures, but ensure that good, ergonomic postures are also dynamic. Switching between sitting, standing and moving while ensuring that the musculoskeletal frame is not under any unnecessary tension can help sedentary workers avoid the onset of MSDs and other health problems.

Reduce the spread of COVID and influenza by improving building ventilation
Posted: September 14, 2021 Filed under: behavior, Breathing/respiration, COVID, health | Tags: air circulation, airborne pathogens, Cholera, influenza, John Snow, ventilation 1 CommentAdapted from the superb article by Sarah Zhang, The plan to stop every respiratory virus at once. The Atlantic. (September 7, 2021).
With good clean air circulation, the risk of transmitting or contracting airborne disease such as COVID-19 during air travel is very low (Pombal, Hosegood & Powell, 2020). Pombal, Hosegood & Powell, 2020 point out that modern airplanes maintain clean air by circulating a mix of fresh air and air recycled through HEPA filter. Air enters from overhead air inlets and flows downward toward floor level outlets at the same seat row or nearby rows. There is little airflow forward and backward between rows.
The risk of transmission or contracting airborne dieases is very high if the airplane ventilation system is not working while passengers are in the plane. For example, when a jet airliner with 54 persons aboard was delayed on the ground for three hours with an inoperative ventilation system 72 % of the passengers became ill with symptoms of cough, fever, fatigue, headache, sore throat and myalgia within 72 hours (Moser et al.,1979).
To reduce the risk of COVID and other airborne infections such as influenza, government policies need to implement strategies to reduce exposure to airborne pathogens and optimize the immune system. By improving ventilation that reduces and removes airborne pathogens, thousands, if not millions, lives will be saved from being infected or dying of COVID or influenza.
Before the COVID pandemic between 2010 and 2020 an average of 39,900 people a year died of influenza in the United States and during a severe influenza season such as that occurred in 2017-2018, 61,000 people died (CDC, 2021). Influenza, just as COVID, is caused by an airborne pathogens (viruses). Although wearing masks significantly reduces the airborne spread of the pathogens, the long term preventative solution is to implement indoor ventilation strategies so that the air is not contaminated in the same way that we expect drinking water not to cause illness. From a public health perspective, changing external environment so the virus is cannot spread is a more effective strategy than depending upon individuals’ actions to prevent the spread of the pathogens.
By improving the air filtration and fresh air circulation in rooms and buildings, COVID, influenza virus and other airborne pathogens can be significantly reduced just as that has been done in modern airplanes. This demands changes in building ventilation codes and design. It means changing the physical infrastructure and upgrading ventilation systems so that only fresh and/or filtered air circulates through the rooms. This infrastructure improvement would be analogous to what occurred in the 19th century in eventually eliminating the cholera epidemics that killed thousands of people a year.
For example in England during the 1831-1832 and 1848 cholera epidemics more than 50,000 people died each year as they became infected with the toxigenic bacterium Vibrio cholerae which was present the water or foods contaminated with feces from a a person infected with cholera bacterium. Approximately 1 in 10 people who get sick with cholera will develop severe symptoms and without treatment, death can occur within hours (CDC, 2021).
In Londong during the 1854 cholera epidemic Dr. John Snow observed that people who got cholera were drawing water from a the same water pump on Broad Street. He persuaded the authorities to remove the pump handle which eliminated the use of the contaminated water and stopped the spread of the Cholera.
The water pump in Broadwick Street.
This public health intervention provided some of the rationale in 19th century to build the infrastructure to provide clean drinking water and appropriate sewage disposal, so that cholera, typhoid as well as other waterborne diseases epidemics would not enter the drinking water supply.
We now need a similar infrastructure improvement to provide clean air in buildings to stop the spread of COVID-19 variants and influenza. How ventilation affects the spread a virus in a class room is illustrated in the outstanding graphical modeling by Nick Bartzokas et al. (February 26, 2021) in the New York Times article, Why opening windows is a key to reopening schools. The spatial guidelines need to be based upon air flow and not on the distance of separation.
In summary, to prevent future airborne illnesses, local, state and federal government need to create and implement ventilation standards so that airborne pathogens are not spread indoors by contaminated air. This is not rocket science! It is a very solvable problem and has been implemented in airplanes. When the air is HEPA filtered so that passengers do not rebreathe each other’s potentially contaminated exhaled air, airborne transmission is very low. Let’s do the same for the air circulating in buildings.

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

Each person who died had about 2 or 3 types of pre-existing co-morbidities such as cardiovascular disease, hypertension, diabetes, obesity, congestive heart failure, chronic kidney disease, respiratory disease and cancer (Ssentongo et al., 2020; Gold et al., 2020). The greater the frequency of comorbidities the greater the risk of death, as shown in Figure 2.

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

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

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

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

Reactivate your second heart

Adapted from: Almendras, M. & Peper, E. (2021). Reactivate your second heart. Biofeedback, 49(4), 99-102. https://doi.org/10.5298/1081-5937-49.04.07
Have you ever wondered why after driving long distances or sitting in a plane for hours your feet and lower leg are slightly swollen (Hitosugi, Niwa, & Takatsu, 2000)? It is the same process by which soldiers standing in attention sometimes faint or why salespeople or cashiers, especially those who predominantly stand most of the day, have higher risk of developing varicose veins. By the end of the day, they feel that their legs being heavy and tired? In the vertical position, gravity is the constant downward force that pools venous blood and lymph fluid in the legs. The pooling of the blood and reduced circulation is a contributing factor why airplane flights of four or more hours increases the risk for developing blood clots-deep vein thrombosis (DVT) (Scurr, 2002; Kuipers et al., 2007). When blood clots reaches the lung, they can cause a pulmonary embolisms that can be fatal. In other cases, they may even travel to the brain and cause strokes.[1]
Sitting without moving the leg muscles puts additional stress on your heart, as the blood and lymph pools in the legs. Tightening and relaxing the calf muscles can prevent the pooling of the blood. The inactivity of your calf muscles does not allow the blood to flow upwards. The episodic contractions of the calf muscles squeezes the veins and pumps the venous blood upward towards the heart as illustrated in figure 1. Therefore, it is important to stand, move, and walk so that your calf muscle can act as a second heart (Prevosti, April 16, 2020).
Figure 1. Your calf muscles are your second heart! The body is engineered so that when you walk, the calf muscles pump venous blood back toward your heart. Reproduced by permission from Dr. Louis Prevosti of the Center for Vein Restoration (https://veinatlanta.com/your-second-heart/).
To see the second heart in action watch the YouTube video, Medical Animation Movie on Venous Disorders, by the Sigvaris Group Europe (2017).
If you stand too long and experienced slight swelling of the legs, raise your feet slightly higher than the head, to help drain the fluids out of the legs. Another way to reduce pooling of fluids and prevent blood clots and edema is to wear elastic stockings or wrap the legs with intermittent pneumatic compression (IPC) devices that periodically compresses the leg (Zhao et al., 2014). You can also do this by performing foot rotations or other leg and feet exercises. The more the muscle of the legs and feet contract and relax, the more are the veins episodically compressed which increases venous blood return. Yet in our quest for efficiency and working in front of screens, we tend to sit for long time-periods.
Developing sitting disease
Have you noticed how much of the time you sit during the day? We sit while studying, working, socializing and entertaining in front of screens. This sedentary behavior has significantly increased during the pandemic (Zheng et al, 2010). Today, we do not need to get up because we call on Amazon’s Alexa, Apple’s Siri or Google’s Hey Google to control timers, answer queries, turn on the lights, fan, TV, and other home devices. Everything is at our fingertips and we have finally become The Jetsons without the flying cars (an American animated sitcom aired in the 1960s). There is no need to get up from our seat to do an activity. Everything can be controlled from the palm of our hand with a mobile phone app.
With the pandemic, our activities involve sitting down with minimum or no movement at all. We freeze our body’s position in a scrunch–a turtle position–and then we wonder why we get neck, shoulder, and back pains–a process also observed in young adults or children. Instead of going outside to play, young people sit in front of screens. The more we sit and watch screens, the poorer is our mental and physical health (Smith et al., 2020; Matthews et al., 2012). We are meant to move instead of sitting in a single position for eight or more hours while fixating our attention on a screen.
The visual stimuli on screen captures our attention, whether it is data entry, email, social media, or streaming videos (Peper, Harvey & Faass, 2020). While at the computer, we often hold up our index finger on the mouse and wait with baited breath to react. Holding this position and waiting to click may look harmless; however, our right shoulder is often elevated and raised upward towards our ear. This bracing pattern is covert and contributes to the development of discomfort. The moment your muscles tighten, the blood flow through the muscle is reduced (Peper, Harvey, & Tylova, 2006). Muscles are most efficient when they alternately tighten and relax. It is no wonder that our body starts to scream for help when feeling pain or discomfort on our neck, shoulders, back and eyes.
Why move?

The importance of tightening and then relaxing muscles is illustrated during walking. During the swing phase of walking, the hip flexor muscles relax, tighten, relax again, tighten again, and this is repeated until the destination is reached. It is important to relax the muscles episodically for blood flow to bring nutrients to the tissue and remove the waste product. Most people can walk for hours; however, they can only lift their foot from the floor (raise their leg up for a few minutes) till discomfort occurs.
Movement is what we need to do and play is a great way to do it. Dr. Joan Vernikos (2016) who conducted seminal studies in space medicine and inactivity physiology investigated why astronauts rapidly aged in space and lost muscle mass, bone density and developed a compromised immune system. As we get older, we are hooked on sitting, and this includes the weekends too. If you are wondering how to separate from your seat, there are ways to overcome this. In the research to prevent the deterioration caused by simulating the low gravity experience of astronauts, Dr. Joan Vernikos (2021) had earthbound volunteers lie down with the head slightly lower than the feet on a titled bed. She found that standing up from lying down every 30-minutes was enough to prevent the deterioration of inactivity, standing every hour was not enough to reverse the degeneration. Standing stimulated the baroreceptors in the neck and activated a cardiovascular response for optimal health (Vernikos, 2021).
We have forgotten something from our evolutionary background and childhood, which is to play and move around. When children move around, wiggle, and contort themselves in different positions, they maintain and increase their flexibility. Children can jump and move their arms up, down, side to side, forward, and backward. They do this every day, including the weekends.
When was the last time you played with a child or like a child? As an adult, we might feel tired to play with a child and it can be exhausting after staring at the screen all day. Instead of thinking of being tired to play with your child, consider it as a good workout. Then you and your child bond and hopefully they will also be ready for a nap. For you, not only do you move around and wake up those muscles that have not worked all day, you also relax the tight muscles, stretch and move your joints. Do playful activities that causes the body to move in unpredictable fun ways such as throwing a ball or roleplaying being a different animal. It will make both of you smile–smiling helps relaxation and rejuvenates your energy.
It is not how much exercise you do, it is how long you sit. The longer you sit without activating your second heart the more are you at risk for cardiovascular disease and diabetes independent of how much exercise you do (Bailey et al., 2019).
Use it or lose it! Activate your calves!
- Interrupt sitting at your desk/computer every 30-minutes by getting up and walking around.
- Stand up and walk around when using your phone.
- Organize walking meetings instead of sitting around a table.
- Invest in a sit-stand desk while working at the computer. While working, alternate positions. There should be a balance between standing and sitting, because too much of one can lead to problems. By taking a short standing up break to let your blood pump back to the heart is beneficial to avoid health problems. Exercise alone, a fancy new ergonomic chair or expensive equipment is not enough to be healthy, it is important to add those mini breaks in between (Buckley et al, 2015).

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