Hope for Dry eyes and Eye Strain: How Breathing-Blinking Patterns Influence Dry Eye.

Many times during the day, I let my shoulders and face relax, and with each exhalation I feel the upper eyelids slightly dropping down at the same time as I am relaxing my jaw and mouth while sitting tall. I sense my tongue and throat sinking and feeling an increase in the space between my upper and lower molars. At the same time, I sense my eyes becoming soft and sinking down as my face muscle relax and are pulled down by gravity while sensing a gentle smile. My eyes are not trying to focus on anything. I continue to breathe slowly allowing a pause before inhaling and feel totally safe and at peace. While doing this, I sense moisture at the lower eyelids. After I have inhaled and as I exhale, I slowly open my eyes, and return to my work. My eyes feel slightly moist and as I blink, the eyelids glide smoothly over the corneal surface.
Background
Dry eyes and eye strain are far more common than most people realize. More than 50% of adults in the United States and Europe experience irritated or burning eyes, dryness, eye strain, headaches, tired or heavy eyes, sensitivity to bright light, and general eye discomfort (Wozniak et al., 2025). The prevalence increases with age and is higher among people who smoke, wear contact lenses, or spend excessive time looking at screens—typically more than six hours per day (Uchino et al,, 2013).
Prolonged, intense screen use—often referred to as digital eye strain or computer vision syndrome—occurs when people focus and concentrate, and the muscles involved with near vision contract and do not relax (Chu et al., 2014). During near vision, the ciliary muscles tighten around the lens to allow near focus, and the medial rectus muscles contract to converge the eyes. These muscles stay contracted and only relax when looking into the distance. This ongoing tension and increased sympathetic activation combined with reduced blinking decrease tearing, and contribute to dry eye symptoms because the tears are not able to provide adequate moisture. As a result, the eyes may become irritated, red and inflamed, which increases eye discomfort (Sheppard & Wolffsohn, 2018; Portello et al., 2012; Sheedy et al., 2003).
When someone is vigilant, fearful, or anticipates a threat, sympathetic activation increases (Ranti et al., 2020) and “eye blink are inhibited at precise moments in time so as to minimize the loss of visual information that occurs during a blink. The more important the visual information is to the viewer, the more likely he or she will be to inhibit blinking” (Ranti et al., 2020).
Without being aware, many people are in a chronic state of vigilance and unknowingly are scanning the world for threats to which they must react. Clinically, I often observe this when guiding clients in relaxation. For example, when I give the instruction, “Let me lift your hand,” some clients immediately lift their hand towards me. This nonverbal response suggests that they are constantly vigilant and are monitoring the world around them—always ready to act instead of trusting that they do not have to act and that the world is safe. In most cases, their breathing pattern tends to be shallow and thoracic.
Would it be possible that this ongoing vigilance,which increases sympathetic arousal contributes to the experience of dry eye syndrome? It could be one factor explaining why women have a higher incidence of dry eye disease as well as anxiety than men since the world is often less safe for women, and they breathe more thoracically and less diaphragmatically (abdominally) than men. Shallow chest breathing is also associated with increased in anxiety (Fugl-Meyer, 1974; Mendes et al., 2020; Wilhelm et al., 2001; Banushi eat al., 2023; McLean et al., 2011; Jalnapurkar, et al., 2018).
Note: The risk of dry eye can also be further increased by a wide range of medical conditions and medications, such as diabetes; glaucoma and glaucoma medications; allergies; autoimmune diseases; arthritis; thyroid disease; high cholesterol; acne treatments; antihistamines; antidepressants; and a history of refractive surgery, conjunctival infections, or corneal abrasions. Dry eye also occurs more frequently in women (Mohamed et al., 2024).
What is usually recommended to resolve dry eyes
The primary and effective first-line treatment to reduce the symptoms of dry eye disease is the use of artificial tears (lubricating eye drops) to provide relief (Maity et al., 2025). Another recommendation to reduce eye strain associated with computer use is to implement the 20/20/20 rule developed by the American Optometric Association–take a 20-second break every 20 minutes and look at something 20 feet away (AOA, 2026). Although the 20/20/20 practice can reduce eye strain and momentarily reduce some of the symptoms associated with dry eye disease especially if the eyes are closed, how we orient, breathe and look may contribute to the experience of dry eye discomfort.
Experience how to evoke dry eyes
Sit comfortably, look around, and observe how your eyes feel. Close your eyes. Now imagine there is a threat. Take a very quick gasp through an open mouth by inhaling into your upper chest and keep breathing very shallowly and irregularly. At the same time, open your eyes wide while being vigilant and looking for danger. Simultaneously, tense your body, inclining it slightly backward as if trying to avoid something. Do not blink, as you may miss the potential threat approaching you (adapted from Lemeignan et al., 1990; Bloch, 2017). A sample physiological recording of this pattern is shown in Figure 1.

Figure 1. Breathing pattern in response to a threat; a rapid gasp into the chest and pulling the abdomen in to protect while breathing shallowly and rapidly.
Most participants report that almost immediately they feel their eyes getting cooler and after 15 seconds, drier. This facial, breathing, and posture pattern is an exaggeration of the somatic expression of fear that is evoked when we are vigilant and feel unsafe, and it increases sympathetic arousal (Kalawski, 2020).
In most cases, this pattern is automatic, and occurs without awareness, and increases sympathetic activity (Narkiewicz et al., 2006). On the other hand, slow diaphragmatic breathing tends to reduce sympathetic activity (Harada et al., 2014; Lehrer & Gevirtz, 2014). Clinically, the vigilance pattern can often be observed as a person slightly lifts and expands their chest during inhalation and drops and constricts it during exhalation, while breathing shallowly and rapidly without any abdomen expansion or constriction. It is often punctuated with brief breath holding and a reduced blinking rate during concentration.
To investigate these observations more systematically, we compared the practice of gasping while opening the eyes with gentle exhalation while opening the eyes—a pattern that may reduce sympathetic activation and alter the subjective sensation of eye dryness.
Participants: 13 males and 13 females; average age, 39 years
Procedure: While sitting comfortably with their eyes closed, participants were guided through the following two practices:
1.Gasp while opening the eyes
Sit comfortably and look around and observe how your eyes feel. Now close your eyes. Now imagine there is a threat. Take a very quick gasp through an open mouth by inhaling into your upper chest and keep breathing very shallowly and irregularly. At the same time, open your eyes wide while being vigilant and looking for danger. Simultaneously, tense your body, inclining it slightly backward as if trying to avoid something. Do not blink, as you may miss the potential threat approaching you. Repeat three times.
2. Gentle exhalation while opening the eyes
Sit comfortably and look around and observe how your eyes feel. Now close your eyes. Breathe comfortably and inhale by allowing your abdomen to extend and widen while feeling your eyes sinking in their sockets and becoming softer as you gently start exhaling. While gently exhaling, begin to open your eyes very slowly, looking down through your eyelashes without caring what you see, allowing your jaw and face muscles to relax and feeling a slight smile. When you feel the urge to inhale, allow your eyes to close and let your abdomen expand as you inhale slowly. Repeat three times.
After these two practices, the participants filled out a short assessment questionnaire in which they rated how their eyes felt on a scale from -5 (dry), 0 (normal), to 5 (moist/tearing), and rated which eye-opening procedure allowed their eyes to be more relaxed and moist.
Results
92.3% of the participants reported that opening their eyes during exhalation significantly increased eye relaxation and moisture, as shown in Figure 2. A one-way analysis of variance (ANOVA) revealed a significant difference between the inhale condition (M = −0.19, n = 26) and the exhale condition (M = 1.00, n = 25), F(1, 49) = 9.65, p = .003. The experience of eye irritation was correlated (r = 0.64) with the self-rating of experiencing anxiety and fear during the last three months.

Figure 2. Gently opening the eyes during exhalation increases the experience of moisture and relaxation in the eyes.
Discussion
The results suggest that increased moisture and eye relaxation could be evoked by changing breathing-blinking patterns. Nearly all participants experienced an increase in tearing and eye relaxation; however, long-term benefits most likely occur if the person implements this practice many times during the day. By changing the breathingg-blink pattern and peacefully looking at the world with a smile, one would decrease sympathetic arousal and increase parasympathetic activity. This approach should be taught as the first self-care intervention to reduce eye irritation.
Recommendations to decrease dry eye and improve eye health
- Experience how the two different breathing and eye-opening practices described above affect your eye dryness or moistness.
- When you sense the first onset of minimal eye discomfort or when looking at screens on your computer or cellphone, implement the following practice for about 10 to 15 seconds. Allow your eyelids to close. Be aware of the sensations in your eyes, let your face and jaw relax as if they are being pulled down by gravity while sensing the eyes becoming soft and sinking into their sockets. Breathe diaphragmatically by allowing the abdomen to expand when you inhale. While gently exhaling, slowly open your eyes slightly while looking down with a gentle smile and sensing the moisture beginning to occur in the eyes. Repeat twice.
- During the day, implement the 20/20/20 vision-regeneration practice (every 20 minutes, take a 20-second break and look at something 20 feet away without caring what you see), as shown in Figure 3.
- Read and incorporated the many practices described in the superb book, Vision for Life; Ten Steps to Natural Eye Improvement, by Meir Schneider (2012).

Figure 3. The 20/20/20 rule poster to prevent eye strain (AOA, 2026).
Do these practices many times and be aware of the sensations in your eyes and face. This passive awareness, in conjunction with slower breathing, tends to reduce sympathetic arousal and increase parasympathetic activity, which facilitates increased tearing. As one participant reported when she practiced this:
What a surprise it was when I closed my eyes and breathed slowly and diaphragmatically, and then, as I began to exhale, I very slowly began to open my eyes while looking down and through my eyelashes, while feeling my eyes sink into their sockets. Tearing occurred spontaneously, and my eyes felt lubricated. What a relief. It provided hope that I could help myself instead of only depending on lubricating eye drops whenever my eyes felt dry and irritated.
Two books to maintain and improve vision and reduce techstress
Vision for Life: Ten Steps to Natural Eye Improvement by Meir Schneider (2012) offers many strategies you can immediately incorporate into your daily life to improve and restore your vision. It provides guidelines on how to reverse developing vision issues before they cause damage and how to remedy existing problems, including near- and far-sightedness, lazy eye, as well as more serious conditions such as cataracts, glaucoma, optic neuritis, detached retinas and retinal tears, macular degeneration, and retinitis pigmentosa.

TechStress: How Technology is Hijacking our Lives, Strategies for Coping, and Pragmatic Ergonomics by Erik Peper, Richard Harvey, and Nancy Fsass (2020) offers practical tools to avoid the evolutionary traps that trip us up and address the problems associated with technological overuse. It includse effective strategies and practices that individuals can use to optimize their workspace, reduce physical strain, correct posture, and improve vision. It provides fresh insights on reducing stress and enhancing health.

Ensorcelled: Breaking the Digital Enchantment

My mom called, “Stop playing on your computer and come for dinner!” I heard her, but I was way too into my game. It felt like I was actually inside it. I think I yelled “Yeah!” back, but I didn’t move.
A few seconds later, I was totally sucked into this awesome world where I was conquering other galaxies. My avatar was super powerful, and I was winning this crazy battle.
Then, all of a sudden, my mom came into my room and just turned off the computer. I was so mad. I was about to win! The real world around me felt boring and empty. I didn’t even feel hungry anymore. I didn’t say anything, I just wanted to go back to my game.
For some, the virtual world feels more real and exciting than the actual one. It can seem more vivid precisely because they have not yet tasted the full, multi-dimensional richness of real human connection, those moments when you feel seen, touched, and understood.
This theme comes vividly alive in my son Eliot Peper’s new novella, Ensorcelled. I am so proud of him. He has crafted a story in which a young boy, captured by the spell of the immersive digital world, discovers that real-life experiences carry far deeper meaning. I won’t give away the plot, but the story creates the experience, it doesn’t just tell it. It reminds us that meaning and belonging arise through genuine connection, not through screens. As Eliot writes, “Sometimes a story is the only thing that can save your life.” It’s a story everyone should read.
The effects of our immersive digital world
Our new world of digital media can take over the reality of actual experiences. It is no wonder that more young people feel stressed and have social anxiety when they have to make an actual telephone call instead of texting (Jin, 2025). They also experience a significant increase in anxiety and depression and feel more awkward initiating in-person social communication with others. The increase in mental health problems and social isolation affects predominantly those who are cellphone and social media natives; namely, those who started to use social media after Facebook was released in 2004 and the iPhone in 2007 (Braghieri et al., 2022).
Students who are most often on their phone whether streaming videos, scrolling, texting, watching YouTube, Instagram or TikTok, and more importantly responding to notifications from phones when they are socializing, report higher levels of loneliness, depression and anxiety as shown inf Figure 1 (Peper & Harvey 2018). They also report less positive feelings and energy when they communicate with each other online as compared to in person (Peper & Harvey, 2024).

Figure 1. The those with the highest phone use were the most lonely, depressed and anxious (Peper and Harvey, 2018).
Even students’ sexual activity has decreased in U.S. high-school from 2013 to 2023 and young adults (ages 18-44) from 2000-2018 (CDC, 2023; Ueda et al., 2020). Much of this may be due to the reality that adolescents have reduced face-to-face socializing (dating, parties, going out) while increasing their time on digital media (Twenge et al., 2019).
What to do
As a parent it often feels like a losing battle to pull your child, or even yourself, away from the intoxicating digital media, since the digital world is supercharged with AI-generated media. It is all aimed at capturing eyeballs (your attention and time), resulting reducing genuine human social connection. (Peper at al., 2020; Haidt, 2024). To change behavior is challenging and yet rewarding. If possible, implement the following (Peper at al., 2020; Twenge, 2025; Haidt, 2024):
- Create tech-free zones. Keep phones and devices out of bedrooms, the dinner table, and family gatherings. Make these spaces sacred for real connection.
- Avoid screens before bedtime. Turn off screens at least an hour before bed. Replace scrolling with quiet reflection, reading, or gentle stretching. Read or tell actual stories before bedtime.
- Explore why we turn to digital media. Before you open an app, ask: Why am I doing this? Am I bored, anxious, or avoiding something? Awareness shifts behavior.
- Provide unstructured time. Let yourself and your children be bored sometimes. Boredom sparks creativity, imagination, and self-discovery.
- Create shared experiences. Plan family activities that don’t involve screens—cooking, hiking, playing music, or simply talking. Real connection satisfies what digital media only mimics.
- Implement social support. Coordinate with other parents, friends, or colleagues to agree on digital limits. Shared norms make it easier to follow through.
- Model what you want your children to do. Children imitate what they see. When adults practice digital restraint, kids learn that real life matters more than screen life.
We have a choice.
We can set limits now and experience real emotional connection and growth or become captured, enslaved, and manipulated by the corporate creators, producers and sellers of media.
Read Ensorcelled. which uses storytelling, the traditional way to communicate concepts and knowledge. Read it, share it. It may change your child’s life and your own.

Abstract
Smartphones are an indispensable part of our lives. Unfortunately too much of a ‘good thing’ regarding technology can work against us, leading to overuse, which in turn influences physical, mental and emotional development among current ‘Generation Z’ and ‘Millennial’ users (e.g., born 1997-2012, and 1981-1996, respectively). Compared to older technology users, Generation Z report more mental and physical health problems. Categories of mental health include attentional deficits, feelings of depression, anxiety social isolation and even suicidal thoughts, as along with physical health complaints such as sore neck and shoulders, eyestrain and increase in myopia. Long duration of looking downward at a smartphone affects not only eyestrain and posture but it also affects breathing which burden overall health. The article provides evidence and practices so show how technology over use and slouching posture may cause a decrease in social interactions and increases in emotional/mental and physical health symptoms such as eyestrain, myopia, and body aches and pains. Suggestions and strategies are provided for reversing the deleterious effects of slouched posture and shallow breathing to promote health.
We are part of an uncontrolled social experiment
We, as technology users, are all part of a social experiment in which companies examine which technologies and content increase profits for their investors (Mason, Zamparo, Marini, & Ameen, 2022). Unlike University research investigations which have a duty to warn of risks associated with their projects, we as participants in ‘profit-focused’ experiments are seldom fully and transparently informed of the physical, behavioral and psychological risks (Abbasi, Jagaveeran, Goh, & Tariq, 2021; Bhargava, & Velasquez, 2021). During university research participants must be told in plain language about the risks associated with the project (Huh-Yoo & Rader, 2020; Resnik, 2021). In contrast for-profit technology companies make it possible to hurriedly ‘click through’ terms-of-service and end-user-license-agreements, ‘giving away’ our rights to privacy, then selling our information to the highest bidder (Crain, 2021; Fainmesser, Galeotti, & Momot, 2023; Quach et al., 2022; Yang, 2022).
Although some people remain ignorant and or indifferent (e.g., “I don’t know and I don’t care”) about the use of our ‘data,’ an unintended consequence of becoming ‘dependent’ on technology overuse includes the strain on our mental and physical health (Abusamak, Jaber & Alrawashdeh, 2022; Padney et al., 2020). We have adapted new technologies and patterns of information input without asking the extent to which there were negative side effects (Akulwar-Tajane, Parmar, Naik & Shah, 2020; Elsayed, 2021). As modern employment shifted from predominantly blue-collar physical labor to white collar information processing jobs, people began sitting more throughout the day. Workers tended to look down to read and type. ‘Immobilized’ sitting for hours of time has increased as people spend time working on a computer/laptop and looking down at smartphones (Park, Kim & Lee, 2020). The average person now sits in a mostly immobilized posture 10.4 hours/day and modern adolescents spent more than two thirds of their waking time sitting and often looking down at their smartphones (Blodgett, et al., 2024; Arundell et al., 2019).
Smartphones are an indispensable part of our lives and is changing the physical and mental emotional development especially of Generation Z who were born between 1997-2012 (Haidt, 2024). They are the social media and smartphone natives (Childers & Boatwright, 2021). The smartphone is their personal computer and the gateway to communication including texting, searching, video chats, social media (Hernandez-de-Menendez, Escobar Díaz, & Morales-Menendez, 2020; Nichols, 2020; Schenarts, 2020; Szymkowiak et al., 2021). It has 100,000 times the processing power of the computer used to land the first astronauts on the moon on July 20, 1969 according to University of Nottingham’s computer scientist Graham Kendal (Dockrill, 2020). More than one half of US teens spend on the average more than 7 hours on daily screen time that includes watching streaming videos, gaming, social media and texting and their attention span has decreased from 150 seconds in 2004 to an average of 44 seconds in 2021 (Duarte, F., 2023; Mark, 2022, p. 96).
For Generation Z, social media use is done predominantly with smartphones while looking down. It has increased mental health problems such as attentional deficits, depression, anxiety suicidal thoughts, social isolation as well as decreased physical health (Haidt, 2024; Braghieri et al., 2023; Orsolini, Longo & Volpe, 2023; Satılmış, Cengız, & Güngörmüş, 2023; Muchacka-Cymerman, 2022; Fiebert, Kistner, Gissendanner & DaSilva, 2021; Mohan et al., 2021; Goodwin et al., 2020).
The shift in communication from synchronous (face-to-face) to asynchronous (texting) has transformed communications and mental health as it allows communication while being insulated from the other’s reactions (Lewis, 2024). The digital connection instead of face-to-face connection by looking down at the smart phone also has decreased the opportunity connect with other people and create new social connections, with three typical hypotheses examining the extent to which digital technologies (a) displace/ replace; (b) compete/ interfere with; and/or, (c) complement/ enhance in-person activities and relationships (Kushlev & Leitao, 2020).
As described in detail by Jonathan Haidt (2024), in his book, The Anxious Generation, the smartphone and the addictive nature of social media combined with the reduction in exercise, unsupervised play and childhood independence was been identified as the major factors in the decrease in mental health in your people (Gupta, 2023). This article focuses less on distraction such as attentional deficits, or dependency leading to tolerance, withdrawal and cravings (e.g., addiction-like symptoms) and focuses more on ‘dysregulation’ of body awareness (posture and breathing changes) and social communication while people are engaged with technology (Nawaz,Bhowmik, Linden & Mitchell, 2024).
The excessive use of the smartphones is associated with a significant reduction of physical activity and movement leading to a so-called sedentarism or increases of sitting disease (Chandrasekaran & Ganesan, 2021; Nakshine, Thute, Khatib, & Sarkar, 2022). Unbeknown to the smartphone users their posture changes, as they looks down at their screen, may also affect their mental and physical health (Aliberti, Invernizzi, Scurati & D’lsanto, 2020).
(1) Explore how looking at your smartphone affects you (adapted from: Peper, Harvey, & Rosegard, 2024)
For a minute, sit in your normal slouched position and look at your smartphone while intensely reading the text or searching social media. For the next minute sit tall and bring the cell phone in front of you so you can look straight ahead at it. Again, look at your smartphone while intensely reading the text or searching social media.
Compare how the posture affects you. Most likely, your experience is similar to the findings from students in a classroom observational study. Almost all experienced a reduction in peripheral awareness and breathed more shallowly when they slouched while looking at their cellphone.
Decreased peripheral awareness and increased shallow breathing that affects physical and mental health and performance. The students reported looking down position reduces the opportunity of creating new social connections. Looking down my also increases the risk for depression along with reduced cognitive performance during class (Peper et al., 2017; Peper et al., 2018).
(2) Explore how posture affects eye contact (adapted from the exercise shared by Ronald Swatzyna, 2023)[2]
Walk around your neighborhood or through campus either looking downwards or straight ahead for 30 minutes while counting the number of eye contacts you make.
Most likely, when looking straight ahead and around versus slouched and looking down you had the same experience as Ronald Swatzyna (2023), Licensed Clinical Social Worker. He observed that when he walked a three-mile loop around the park in a poor posture with shoulders forward in a head down position, and then reversed direction and walked in good posture with the shoulders back and the head level, he would make about five times as many eye contacts with a good posture compared to the poor posture.
Anecdotal observations, often repeated by many educators, suggest before the omnipresent smartphone, students would look around and talk to each other before a university class began. Now, when Generation Z students enter an in-person class, they sit down, look down at their phone and tend not to interact with other students.
(3) Experience the effect of face-to-face in-person communication
During the first class meeting, ask students to put their cellphones away, meet with three or four other students for a few minutes, and share a positive experience that happened to them last week as well as what they would like to learn in the class. After a few minutes, ask them to report how their energy and mood changed.
In our observational class study with 24 junior and senior college students in the in-person class and 54 students in the online zoom class, almost all report that that their energy and positive mood increased after they interacted with each other. The effects were more beneficial for the in-person small group sharing than the online breakout groups sharing on Zoom as shown in Figure 1.

Figure 1. Change in subjective energy and mood after sharing experiences synchronously in small groups either in-person or online.
Without direction of a guided exercise to increase social connections, students tend to stay within their ‘smartphone bubble’ while looking down (Bochicchio et al., 2022). As a result, they appear to be more challenged to meet and interact with other people face-to-face or by phone as is reflected in the survey data that Generation Z is dating much less and more lonely than the previous generations (Cox et al., 2023).
What to do:
- Put the smartphone away so that you do not see it in social settings such as during meals or classes. This means that other people can be present with you and the activity of eating or learning.
- Do not permit smartphones in the classroom including universities unless it is required for a class assignment.
- In classrooms and in the corporate world, create activities that demands face-to-face synchronous communication.
- Unplug from the audio programs when walking and explore with your eyes what is going on around you.
(4) Looking down increases risk of injury and death
Looking down at a close screen reduces peripheral awareness and there by increases the risk of accidents and pedestrian deaths. Pedestrian deaths are up 69% since 2011 (Cova, 2024) and have consistently increased since the introduction of the iPhone in 2007 as shown in Figure 3.

Figure 3. Increase in pedestrian death since the introduction of the iphone (data plotted from https://www.iihs.org/topics/fatality-statistics/detail/pedestrians)
In addition, the increase use of mobile phones is also associated with hand and wrist pain from overuse and with serious injuries such as falls and texting while driving due to lack of peripheral awareness. McLaughlin et al (2023) reports an increase in hand and wrist injuries as well serious injuries related to distracted behaviors, such as falls and texting while driving. The highest phone related injuries (lacerations) as reported from the 2011 to 2020 emergency room visits were people in the age range from 11–20 years followed by 21–30 years.
What to do:
- Do not walk while looking at your smartphone. Attend to the environment around you.
- Unplug from the audio podcasts when walking and explore with your eyes what is going on around you.
- Sit or stop walking when answering the smartphone to reduce the probability of an accident.
- For more pragmatic suggestions, see the book, TechStress: How Technology is Hijacking Our Lives, Strategies for Coping, and Pragmatic Ergonomics, by Peper, Harvey and Faass (2020).
(5) Looking at screens increases the risk of myopia
Looking at a near screen for long periods of time increases the risk of myopia (near sightedness) which means that distant vision is more blurry. Myopia has increased as children predominantly use computers or, smartphones with smaller screen at shorter distances. By predominantly focusing on nearby screens without allowing the eye to relax remodels the eyes structure. Consequently, myopia has increase in the U.S. from 25 percent in the early 1970s to nearly 42 percent three decades later (OHSU, 2022).
Looking only at nearby screens, our eyes converge and the ciliary muscles around the lens contract and remain contracted until the person looks at the far distance. The less opportunity there is to allow the eyes to look at distant vision, the more myopia occurs. in Singapore 80 per cent of young people aged 18 or below have nearsightedness and 20 % of the young people have high myopia as compared to 10 years ago (Singapore National Eye Centre, 2024). The increase in myopia is a significant concern since high myopia is associated with an increased risk of vision loss due to cataract, glaucoma, and myopic macular degeneration (MMD). MMD is rapidly increasing and one of the leading causes of blindness in East Asia that has one of the highest myopia rates in the world (Sankaridurg et al., 2021).
What to do:
- Every 20 minutes stop looking at the screen and look at the far distance to relax the eyes for 20 seconds.
- Do not allow young children access to cellphones or screens. Let them explore and play in nature where they naturally alternate looking at far and near objects.
- Implement the guided eye regenerating practices descrubed in the article, Resolve eyestrain and screen fatigue, by Peper (2021).
- Read Meir Schneider’s (2016) book, Vision for Life, for suggestions how to maintain and improve vision.
(6) Looking down increases tech neck discomfort
Looking down at the phone while standing or sitting strains the neck and shoulder muscles because of the prolonged forward head posture as illustrated in the YouTube video, Tech Stress Symptoms and Causes (DeWitt, 2018). Using a smartphone while standing or walking causes a significant increase in thoracic kyphosis and trunk (Betsch et al., 2021). When the head is erect, the muscle of the neck balance a weight of about 10 to 12 pounds or, approximately 5 kilograms; however, when the head is forward at 60 degrees looking at your cell phone the forces on the muscles are about 60 pound or more than 25 kilograms, as illustrated in Figure 4 (Hansraj, 2014).

Figure 4. The head forward position puts as much as sixty pounds of pressure on the neck muscles and spine (by permission from Dr. Kenneth Hansraj, 2014).
This process is graphically illustrated in the YouTube video, Text Neck Symptoms and Causes Video, produced by Veritas Health (2020).
What to do:
- Keep the phone in front of you so that you do not slouch down by having your elbow support on the table.
- Every ten minutes stretch, look up and roll your shoulders backwards.
- Wear a posture feedback device such as the UpRight Go 2 to remind you when you slouch to change posture and activity (Peper et al., 2019; Stuart, Godfrey & Mancini, 2022).
- Take Alexander Technique lessons to improve your posture (Cacciatore, Johnson, & Cohen, 2020; AmAT, 2024; STAT, 2024).
(7) Looking down increases negative memory recall and depression
In our previous research, Peper et al. (2017) have found that recalling hopeless, helpless, powerless, and defeated memories is easier when sitting in a slouched position than in an upright position. Recalling positive memories is much easier when sitting upright and looking slightly upward than sitting slouched position. If attempting to recall positive memories the brain has to work hard as indicated by an significantly higher amplitudes of beta2, beta3, and beta4 EEG (i.e., electroencephalograph) when sitting slouched then when sitting upright (Tsai et al., 2016).
Not only does the postural position affect memory recall, it also affects mental math under time-pressure performance. When students sit in a slouched position, they report that is much more difficult to do mental math (serial 7ths) than when in the upright position (Peper et al., 2018). The effect of posture is most powerful for the 70% of students who reported that they blanked out on exams, were anxious, or worried about class performance or math. For the 30% who reported no performance anxiety, posture had no significant effect. When students become aware of slouching thought posture feedback and then interrupt their slouching by sitting up, they report an increase in concentration, attention and school performance (Peper et al., 2024).
How we move and walk also affects our subjective energy. In most cases, when people sit for a long time, they report feeling more fatigue; however, if participants interrupt sitting with short movement practices they report becoming less fatigue and improved cognition (Wennberg et al., 2016). The change in subjective energy and mood depends upon the type of movement practice. Peper & Lin (2012) reported that when students were asked to walk in a slow slouching pattern looking down versus to walk quickly while skipping and looking up, they reported that skipping significantly increased their subjective energy and mood while the slouch walking decreased their energy. More importantly, student who had reported that they felt depressed during the last two years had their energy decrease significantly more when walking very slowly while slouched than those who did not report experiencing depression. Regardless of their self-reported history of depression, when students skipped, they all reported an increase in energy (Peper & Lin, 2012; Miragall et al., 2020).
What to do:
- Walk with a quick step while looking up and around.
- Wear a posture feedback device such as the UpRight Go 2 to remind you when you slouch to change posture and activity (Peper et al., 2019; Roggio et al., 2021).
- When sitting put a small pillow in the mid back so that you can sit more erect (for more suggestions, see the article by Peper et al., 2017a, Posture and mood: Implications and applications to therapy).
- Place photo and other objects that you like to look a slightly higher on your wall so that you automatically look up.
(8) Shallow breathing increases the risk for anxiety
When slouching we automatically tend to breathe slightly faster and more shallowly. This breathing pattern increases the risk for anxiety since it tends to decrease pCO2 (Feinstein et al., 2022; Meuret, Rosenfield, Millard & Ritz, 2023; Paulus, 2013; Smits et al., 2022; Van den Bergh et al., 2013). Sitting slouched also tends to inhibit abdominal expansion during the inhalation because the waist is constricted by clothing or a belt –sometimes labeled as ‘designer jean syndrome’ and may increase abdominal symptoms such as acid reflux and irritable bowel symptoms (Engeln & Zola, 2021; Peper et al., 2016; Peper et al., 2020). When students learn diaphragmatic breathing and practice diaphragmatic breathing whenever they shallow breathe or hold their breath, they report a significant decrease in anxiety, abdominal symptoms and even menstrual cramps (Haghighat et al., 2020; Peper et al., 2022; Peper et al., 2023).
What to do:
- Loosen your belt and waist constriction when sitting so that the abdomen can expand.
- Learn and practice effortless diaphragmatic breathing to reduce anxiety.
Conclusion
There are many topics related to postural health and technology overuse that were addressed in this article. Some topics are beyond the scope of the article, and therefore seen as limitations. These relate to diagnosis and treatment of attentional deficits, or dependency leading to tolerance, withdrawal and cravings (e.g., addiction-like symptoms), or of modeling relationships between factors that contribute to the increasing epidemic of mental and physical illness associated with smartphone use and social media, such as hypotheses examining the extent to which digital technologies (a) displace/ replace; (b) compete/ interfere with; and/or, (c) complement/ enhance in-person activities and relationships. Typical pharmaceutical ‘treat-the-symptom’ approaches for addressing ‘tech stress’ related to technology overuse includes prescribing ‘anxiolytics, pain-killers and muscle relaxants’ (Kazeminasab et al., 2022; Kim, Seo, Abdi, & Huh, 2020). Although not usually included in diagnosis and treatment strategies, suggesting improving posture and breathing practices can significantly affect mental and physical health. By changing posture and breathing patterns, individuals may have the option to optimize their health and well-being.

[2] I thank Ronald Swatzyna (2023), Licensed Clinical Social Worker for sharing this exercise with me. He discovered that a difference in the number of eye contacts depending how he walked. When he walked a 3.1 mile loop around the park in a poor posture- shoulders forward, head down position- and then reversed direction and walked in good posture with the shoulders back and the head level, that that he make about 5 times as many eye contacts with good posture compared to the poor posture. He observed that he make about five times as many eye contacts with good posture as compared to the poor posture.
