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.”

Erik Peper and Meir Schneider
As a young child I laid on the couch and I read one book after the other. Hours would pass as I was drawn into the stories. By the age of 12 I was so nearsighted that I had to wear glasses. When my son started to learn to read, I asked him to look away at the far distance after reading a page. Even today at age 34, he continues this habit of looking away for a moment at the distance after reading or writing a page. He is a voracious reader and a novelist of speculative fiction. His vision is perfect. –Erik Peper
How come people in preliterate, hunting and gatherer, and agricultural societies tend to have better vision and very low rates of nearsightedness (Cordain et al, 2003)? The same appear true for people today who spent much of their childhood outdoors as compared to those who predominantly stay indoors. On the other hand, how come 85% of teenagers in Singapore are myopic (neasighted) and how come in the United States myopia rate have increased for children from 25% in the 1970s to 42% in 2000s (Bressler, 2020; Min, 2019)?
Why should you worry that your child may become nearsighted since it is easy correct with contacts or glasses? Sadly, in numerous cases, children with compromised vision and who have difficulty reading the blackboard may be labeled disruptive or having learning disability. The vision problems can only be corrected if the parents are aware of the vision problem (see https://www.covd.org/page/symptoms for symptoms that may be related to vision problems). In addition, glasses may be stigmatizing and children may not want to wear glasses because of vanity or the fear of being bullied.
The recent epidemic of near sightedness is paritally a result of disrespecting our evolutionary survival patterns that allowed us to survive and thrive. Throughout human history, people continuously alternated by looking nearby and at the distance. When looking up close, the extraocular muscles contract to converge the eyes and the ciliary muscles around the lens contract to increase the curvature of the lens so that the scene is in focus on the retina — this muscle tension creates near visual stress.
The shift from alternating between far and near vision to predominantly near vision and immobility
Figure 2. The traditional culture of Hdzabe men in Tanzania returning from a hunt. Notice how upright they walk and look at the far distance as compared to young people today who slouch and look predominantly at nearby screens.
Experience the effect of near visual stress.
Bring your arm in front of you and point your thumb up. Look at your thumb on the stretched out arm. Keep focusing on the thumb and slow bring the thumb four inches from your nose. Keep focusing on the thumb for a half minute. Drop the arm to the side, and look outside at the far distance.
What did you experience? Almost everyone reports feeling tension in the eyes and a sense of pressure inside around and behind their eyes. When looking at the distance, the tension slowly dissipates. For some the tension is released immediately while for others it may take many minutes before the tension disappears especially if one is older. Many adults experience that after working at the computer, their distant vision is more fuzzy and that it takes a while to return to normal clarity.
When the eyes focus at the distance, the ciliary muscles around lens relaxes so that the lens can flatten and the extra ocular muscles relax so that the eyes can diverge and objects in the distance are in focus. Healthy vision is the alternation between near and far focus– an automatic process by which the muscles of the eyes tightening and relax/regenerate.
Use develops structure and structure limits use
If we predominantly look at nearby surfaces, we increase near visual stress and the risk of developing myopia. As children grow, the use of their eyes will change the shape of the eyeball so that the muscles will have to contract less to keep the visual object into focus. If the eyes predominantly look at near objects, books, cellphones, tablets, toys, and walls in a room where there is little opportunity to look at the far distance, the eye ball will elongate and the child will more likely become near sighted. Over the last thirty year and escalated during COVID’s reside-in-place policies, children spent more and more time indoors while looking at screens and nearby walls in their rooms. Predominantly focusing on nearby objects starts even earlier as parents provide screens to baby and toddlers to distract and entertain them. The constant near vision remodels the shape of eye and the child will likely develop near sightedness.
Health risks of sightedness and focusing predominantly upon nearby objects
- Increased risk of get into an accident as we have reduced peripheral vision. In earlier times if you were walking in jungle, you would not survive without being aware of your peripheral vision. Any small visual change could indicate the possible presence food or predator, friend or foe. Now we focus predominantly centrally and are less aware of our periphery. Observe how your peripheral awareness decreases when you bring your nose to the screen to see more clearly. When outside and focusing close up the risk of accidents (tripping, being hit by cars, bumping into people and objects) significantly increases as shown in figure 3 and illustrated in the video clip.
Pedestrian accidents (head forward with loss of peripheral vision)
- Myopia increases the risk of eye disorder. The risk for glaucoma, one the leading causes of blindness, is doubled (Susanna, De Moraes, Cioffi, & Ritch, R. 2015). The excessive tension around the eyes and ciliary muscles around the lens can interfere with the outflow of the excess fluids of the aqueous humour through the schlemm canal and may compromise the production of the aqueous humour fluid. These canals are complex vascular structures that maintains fluid pressure balance within the anterior segment of the eye. When the normal outflow is hindered it would contribute to elevated intraocular pressure and create high tension glaucoma (Andrés-Guerrero, García-Feijoo, & Konstas, 2017). Myopia also increases the risk for retinal detachment and tears, macular degeneration and cataract. (Williams & Hammond, 2019).
By learning to relax the muscles around the lens, eye and face and sensing a feeling of soft eyes, the restriction around the schlemm canals is reduced and the fluids can drain out easier and is one possible approach to reverse glaucoma (Dada et al., 2018; Peper, Pelletier & Tandy, 1979).
- Increase in neck and upper back compression when the person cranes their head forward or looks down while reading books/articles, looking at a cellphone or a laptop screen, This often results in an increase of back, neck and shoulder pain as well as headaches (Harvey, Peper, Booiman, Heredia Cedillo, & Villagomez, 2018; Hansraj, 2014).
- Decrease in subjective energy and increase in helpless, hopeless, powerless and defeated thoughts when the person habitually looks down in a slouched position (Peper, Booiman, Lin, & Harvey, 2016; Peper, Lin, Harvey, & Perez, 2017).
WHAT CAN YOU DO?
The solutions are remarkable simple. Respect your evolutionary background and allow your eyes to spontaneously alternate between looking at near and far objects while being upright (Schneider, 2016; Peper, 2021; Peper, Harvey & Faass, 2020).
For yourself and your child
- Let children play outside so that they automatically look far and near.
- When teaching children to read have them look at the distance at the end of every paragraph or page to relax the eyes.
- Limit screen time and alternate with outdoor activities
- Every 15 to 20 minutes take a vision break when reading or watching screens. Get up, wiggle around, move your neck and shoulders, and look out the window at the far distance.
- When looking at digital screens, look away every few minutes. As you look away, close your eyes for a moment and as you are exhaling gently open your eyes.
- Practice palming and relaxing the eyes. For detailed guidance and instruction see the YouTube video by Meir Schneider.
Create healthy eye programs in schools and work
- Arrange 30 minute lesson plans and in between each lesson plan take a vision and movement breaks. Have children get up from their desks and move around. If possible have them look out the window or go outside and describe the furthest object they can see such as the shape of clouds, roof line or details of the top of trees.
- Teach young children as they are learning reading and math to look away at the distance after reading a paragraph or finishing a math problem.
- Teach palming for children.
- During recess have students play games that integrate coordination with vision such as ball games.
- Episodically, have students close their eyes, breathe diaphragmatically and then as they exhale slowly open their eyes and look for a moment at the world with sleepy/dreamy eyes.
- Whenever using screen use every opportunity to look away at the distance and for a moment close your eyes and relax your neck and shoulders.

Monica Almendras and Erik Peper
For almost a year, we have managed to survive this pandemic. As we work in front of screen many people experience screen fatigue (Bailenson, 2021). The tiredness, achiness and depressive feelings have many causes such as sitting disease, reduced social contact, constantly looking at the screen for work, education, socializing, and entertaining, and the increased stress from family illness and economic insecurity. The result is that many people experience low energy, depression, loneliness, anxiety, neck, shoulder, back pain at the end of the day (Son, Hegde, Smith, Wang, & Sasangohar, 2020; Peper & Harvey, 2018).
Yet there is hope to reduce discomfort and increase by implementing simple tips.
Take breaks and take more breaks by getting up from your chair and moving. Taking breaks helps us to clear our minds and it interrupts any ongoing rumination we may have going on. Doing this helps a person be more productive at work or when studying, and at the same time it helps retain more information (Peper, Harvey, & Faass, 2020; Kim, Park, & Headrick, 2018). How many of you reading this actually take a short break at least once during work? We stay in the same sitting position for long periods of time, even holding off to go to the restroom. We tell ourselves ‘one more minute’ or ‘I’ll just finish this and then I’ll go”. Sounds familiar? We know it is not healthy and yet, we continue doing it.
Solution: Set a reminder every twenty minutes to take a short break. Download a program on your computer that will remind you to take a break such as Stretch Break (www.stretchbreak.com). Every twenty minutes a window will pop up on your computer reminding you to stretch. It gives you simple exercises for you to move around and wiggle as shown in figure 1. You can say it breaks the spell from staying frozen in one position in front of your screen. The best part is that yet is free to download on your computer. What more can you ask for?
Figure 1. Stretch break window that pops up on your computer to remind you to stretch.
Stop slouching in front of the screen. We tend to gaze downwards to our device and slouch, which creates tension on our neck and shoulders ((Peper, Lin, Harvey, & Perez, 2017). And yet, we still wonder why people suffer from neck-shoulder pain and headaches. It is time to make a transformation from slouching and feeling aches and pains, to an upright posture to be free of pain.
Solution: Use an UpRight Go 2 device on your upper back or neck is a great way to remind you that you are slouching (Harvey, Peper, Mason, & Joy, 2020). The UpRight is linked via Bluetooth to the App on the mobile phone, and once you calibrate it to an upright posture, you will see and feel a vibrate when you slouch. For people who are on the computer for long hours, this will help you to be aware of your posture.
If wearing a small device on your back is not your cup of tea, or perhaps it is not in your budget at the moment. There is a solution for this, and that means you can download the UpRight Desktop App on your computer or laptop (Chetwynd, Mason, Almendras, Peper, & Harvey, 2020). The desktop version uses the camera from your computer or laptop to monitor your posture; however, at the camera cannot simultaneous be in use with another program such as ZOOM. This version provides immediate feedback through the graphic on the screen as well as, an adjustable auditory signal when you slouch as shown in Figure 2. It is also free to download, and it is available for PC and Mac (https://www.uprightpose.com/desktop-app/).
Figure 2. Posture feedback app. When slouching, the app provides immediate feedback through the graphic on the screen (the posture of figure turns red) and/or an adjustable auditory sound (from: Chetwynd, Mason, Almendras, Peper, & Harvey, 2020)
Relax your eyes and look away from the screen. Many people struggle with dry eyes and eyestrain from looking at the screen for extended time periods. We log out from work, meetings, and class; to staring at the television, tablets, and mobile phones on our free time. It is a nonstop cycle of looking at the screen, while our poor eyes never have a single break. To look at the screen, we tightened our extraocular muscles and ciliary muscles; and the result is near-vision stress (Peper, 2021).
SOLUTION: The solution to relax the eyes and reduce eyestrain will not be to buy new eyeballs online. Instead, here are three easy and free things to reestablish good eyeball health. These were adapted from the superb book, Vision for life: Ten steps for natural eyesight improvement, by Meir Schneider, PhD.
- Look out through a window at a distance tree for a moment after reading an email or clicking a link
- Look up at a distant tree and focus at the details of the branches and leaves each time you have finished a page from a book or eBook.
- Rest and regenerate your eyes with palming (Peper, 2021). To do palming, all you need to do is sit upright, place an object under your elbows (pillow or books) to avoid tensing the neck and shoulders, and cover the eyes with your hands (see figure 3). Cup your hands to avoid pressure on your eyes and with your eyes closed, imagine seeing blackness while breathing slowing from your diaphragm. For five minutes, feel how your shoulders, head, and eyes are relaxing, while doing six breaths per minutes through your nose. Once your five minutes are up, stretch or wiggle around before returning to your work. For detailed instructions, see the YouTube video, Free Webinar by Meir Schneider: May 6, 2019.
Figure 3. Position for palming.
Implement these tips as an experiment for a week and note how it affects you. Many people report that after three weeks, they experience less pain and more energy. By taking charge of your own computer work patterns, you have taken a first e first step into transforming your health.

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