Healthy movement is the new aging

Born on 26 November 1911, Mr Robert Marchand and 105 years old, managed cycling 22.55 km (14 miles) at the national velodrome and set a new record for the furthest distance cycled in one hour for riders over 105. (Reynolds, 2017).

As people age there is an increase in Western Diseases such as hypertension, diabetes, gout, cancer, dementia and  decreases in physical fitness (Milanović et al, 2013Tauber, 2016).   To assume that the cause of these illnesses is the natural process of aging may be too simplistic. Although aging does affect physiology, there are other factors that contribute to the increase in “Western Diseases” such as diet, lifestyle and genetics.

A significant contributing factor of Western Diseases is diet especially  the increase in sugar and simple carbohydrates. Whether you are Pima, Tohono O’odham, and Navajo American Indian Tribes in Arizona, Intuits in Northern Canada, Japanese Americans, or indigenous populations of Kenya, when these people stopped eating their traditional diet and adapted the western high glucose/fructose/simple carbohydrate diet, the degenerative Western Diseases exploded (Bjerregaard et al, 2004; Burkitt & Trowell, 1975; Knowler et al, 1990; Tauber, 2016). Diabetes, hypertension, and cancer which were previously rare skyrocketed within one generation after adapting the Western life style diet. In some of these populations, 30% or more of the adults have diabetes and a significant increase in breast cancer.

The reduction of episodic high intensity physical activity and being sedentary are additional risk factors for the onset of diabetes and cardiovascular disease (Dulloo et al, 2017). As Mensing & Mekel (2015) state, “Sitting is the new smoking.”  Sitting encourages more sitting which leads to nonuse of muscles and causes neural and muscle atrophy.  Our physiology is efficient and will prune/eliminate what is redundant.  This is reflected in the popular phrase, “Use it or lose it.”  As we sit for hours in front of digital devices, use escalators, elevators, or drive cars, we are not using the muscles involved in dynamic movement.  We are usually unaware of this degenerative process. Instead,  we may experience difficulty walking up the stairs  which encourages us to take the escalator or elevator. When we do not use the muscles or are limited in movement by discomfort and pain, we move less. As we move less, we become  weaker which is often labeled as aging instead of non use.

Just, because most people loose fitness, it may not represent what is possible or optimum.  Instead, we may want to emulate the diet and fitness program of Mr. Robert Marchand who at age 103 set a new world record and improved the distance bicycled in one hour from 24.25 km at the age of 101 to 26.92 km at the age of 103. A 11% improvement! As New York Times science writer Gretchen Reynolds reports, “Lifestyle may also matter. Mr. Marchand is “very optimistic and sociable,” The researcher who did the study, Dr. Billat says, “with many friends,” and numerous studies suggest that strong social ties are linked to a longer life. His diet is also simple, focusing on yogurt, soup, cheese, chicken and a glass of red wine at dinner (Reynolds, 2017).

The improvement in bicycling performance and physiological indicators such as ⩒O2max increased (31 to 35 ml.kg-1min-1; +13%), appeared to be due to a change in his training regimen (Billat et al 2016).  At age 101 he changed his bicycling training program from riding at a steady speed for one hour to riding 80% at an easy pace and 20% at high intensity.  This is a  type of interval training and includes enough recovery allows the body the recover and strengthen. This analogous to our evolutionary movement pattern of walking interspersed with short distance high intensity running.

As a hunter and gather we often moved steadily and then had to run very fast to escape a predator or catch an animal.  After extreme exertion, we would rest and regenerate (if we did not escape we would be lunch for the predator). Thus episodic high intensity activity with significant rest/regenerative periods is the movement pattern that allowed our species to survive and thrive. Research studies have confirmed that high intensity interval training offers more physiological benefits–increases cardiorespiratory fitness which is a strong determinant of morbidity and mortality– than moderate intensity continuous training (Weston et al, 2014).

Thus when Mr. Marchard changed his exercise pattern from moderate intensity continuous training to high intensity interval training with enough recovery time he set a new world record at age 103. Two years later he set a new world record at age 105.

Exercise improves brain function and interval training appears to improve brain function most.  When rats had prolonged exercise, the brain’s stores of energy is significantly lowered in the frontal cortex and hippocampus all areas which area involved in thinking and memory. If on the other hand, the animals had a single intense bout of exercise and were allowed to rest and feed than the brain levels of glycogen was 60% high in the frontal and hippocampus areas.  This suggest that the brain can then function better (Matsui et al, 2012).

This perspective is supported by the evolutionary hypothesis discussed by Neuroscientist Daniel Wolpert who points out that brains evolved, not to think or feel, but to direct movement. When movement is no longer needed the brain shrinks and gets reabsorbed which is illustrated by the sea squirt. This animal swims as a juvenile and then anchors on a rock and is passively moved by the currents. Once anchored, it no longer needed to coordinate movement and reabsorb its own nervous system. See Daniel Wolpert’s remarkable TED talk, The real reasons for brains.

The remarkable feat of Mr. Marchand offers suggestions for our own health. Enjoy healthy movement and exercise and incorporate our evolutionary movement patterns:  episodic high intensity followed by regeneration. At the same time include a healthy diet by reducing sugars and simple carbohydrates.  Finally, it helps to have the right genes.

Doctor Mike Evans: What’s the Best Diet? Healthy Eating 101

A healthy diet is much more than just focusing on a single food. People focus so often on adding one type of food or eliminating another such as, “Don’t eat ice cream!”, “Eat chia seeds.” “No red meat.” In almost all cases, it is not just one thing, instead a healthy diet is embedded in awareness and healthy life style choices. Watch the superb common sense white board video presentation by Doctor Mike Evans, What’s the Best Diet? Healthy Eating 101. In this short presentation, he summarizes the best practices known. Implement his approach and your health will significantly improve.


Be aware of evolutionary/ecological traps

Slide1

Being captured by a digital device. From: http://images.gameskinny.com/gameskinny/c9689c75994e58a03dbc5e489d346e55.jpg

How come birds on Midway Island are dying?

How come your son keeps playing computer games even after he said he would stop?

How come you ate all the French fries and the dessert even though you promised yourself to reduce your calorie intake?

How come you procrastinated and did not get up from the couch to exercise?

How come you watched pornography?

The usual answer is absence of will, self-control or self-discipline. The person is automatically blamed for making poor life choices. If you had more self-worth than you would not let yourself get obese, addicted to computer games, or watch pornography. Blaming the victim is easy, however, there are other factors that underlie the person’s covert/unconscious choices. Many of these illness producing behaviors (e.g., overeating, playing the computer games, sitting and sitting) are responses to external cues that in prehistoric times promoted survival, reproduction and health. To respond rapidly and appropriately  to those cues offered a reproductive advantages while not reacting would reduce your survival. In many cases there are no upper limits to turn off our responses to these cues because the more the person responded to those cues the more was there a reproductive advantage. Now, however, our adaptive preferences have become maladaptive because the cues that trigger the same behaviors lead to lower fitness and illness (Schlaepfer et al, 2002; Robertson et al, 2013). The cues have become evolutionary/ecological traps!

Some of the recent evolutionary/ecological traps include:

Vigilance for survival. While playing a computer games, the person rapidly responds and continuously experiences immediate rewards (e.g., successful shooting the target, points, next game level). This process activates the same  survival mechanisms that hunter used for thousands of generations. A visual or auditory stimuli represents  sources of food or danger (a game animal to hunt for food, an attack by a predator or an enemy). The visual/auditory cue captures the person’s attention and if the person reacts to that cue he would probably survive. On the other hand, if he did not react, he may not survive and reproduce. In our modern world, similar stimuli now hijack the neurological pathways that in earlier times supported survival. Over activation of these pathways is a cofactor in the development of ADHD and other disorders (Peper, 2014). For a superb discussion of  how cellphones, computers, gaming and social medial are changing our brains, read Dr. Mari Swingle’s new book, i-Minds (Swingle, 2015)

Energy for survival: Eating carbohydrate/sugary and fat foods are necessary for survival as humans constantly searched for energy sources to support life. Breast milk and almost any fruit that is sweet contain calories and supports growth. If the food was bitter it was usually harmful. For most of our evolutionary past, we would eat as much as possible because food was scarce. There was no evolutionary advantage to limit food intake as the stored calories would supply enough calories to survive during periods of famine. In our modern world, our survival mechanisms have been hijacked by advertising and the oversupply of foods which  contribute to the epidemic of obesity and diabetes.

Being a couch potato and not moving again is again survival mechanism. In a prehistoric world with limited food supply, the less movement (the fewer calories you burned), the longer you could survive. You would move when you needed to build shelter or search for food. Again in a world where shelter and food are often abundant, there is no intrinsic mechanism to initiate movement.

Sexual arousal for reproduction: Men are often captured by pornography. They can watch for hours and feel aroused. The whole porn industry is based upon hijacking our sexual drive for reproduction.

Our brain does not discriminate between actual visual and auditory stimuli, imagined or film/video images. Until the late 19th century everything we saw and heard was real. Only in the 20th century could we produce images and sounds that appeared real. These film, TV , and the ever present digital displays activate the same neurophysiological pathways as when the stimuli were actually real.  A scene on a digital screen triggers the same biological pathways and responses that for thousands of generations supported survival. If we did not respond we would not have survived.  If you have any doubt, watch a scary horror movie and check how you feel afterwards. You may feel more scared, your sleep may be disturbed, your heart rate increased, and you probably interpreted any noise around you as possible danger. Thus, cues in the environment may become evolutionary/ecological traps in the same way that birds on Midway Island in the North Pacific, 2000 miles from any other islands, mistook the attractive coloring of plastics as food. See: https://www.youtube.com/watch?v=dtJFiIXp5Bo. Should the birds be blamed because they have no self-control?

What can you do!

Recognize that modern industries for the sake of profits have hijacked our cues that had evolved to aid survival (Kemp, 2014).

Recognize that not reacting to product cues means inhibiting the intrinsic biological triggered survival responses. Yes, it is possible not react to the stimuli and demonstrate self-control; however, it is not only a problem of will. It is a problem that our cues have been hijacked and tricked for commercial profit.

Society may need to protect its own populations from commercial exploitation of evolutionary/ecological traps. A young child is automatically drawn to the visual stimuli on a smartphone and tablet which parents use to quiet the child during dinner. In this process they are activating the pre-wired biological pathways that captured attention for survival. By over activating these pathways, the brain is changing in response to this activation which increases the risk of developing ADHD, autism, and mood deregulation including anxiety, depression, and anger management, and other forms of addictive behavior (Swingle, 2015). In addition, school performance and memory retention are reduced when students take notes using their keyboard or read text from digital screens (OCallaghan, 2014). It will take the family and society to limit the availability of these cues until self-control has been developed. Similarly, the availability of cheap calories in large food portions, sugars in soft drinks and sugar and fats in snacks, need to be limited if the epidemic of obesity and diabetes is to be reversed.

It may be unreasonable to think that people can easily interrupt their biological responses to cues that have been created to increase profits. We need to take collective responsibility and limit the availability of commercially augmented evolutionary traps and cues in the same way we need to limit the plastic in the ocean so that the birds at Midway Island may be able survive. Without respecting our evolutionary past, our future may not be different from those Midway Island birds.

Go for it: The journey from paraplegia to flying

After a catastrophic event occurs a person often becomes depressed as the future looks bleak. One may keep asking, ”Why, why me?” When people accept–acceptance without resignation— and concentrate on the small steps of the journey towards their goal, remarkable changes may occur. The challenge is to focus on new possibilities without comparing to how it was in the past. The limits of possibility are created by the limits of our beliefs. We may learn from athletes who aim to improve performance whereas clients usually come to reduce symptoms. As Wilson and Peper (2011) point out, Athletes want to go beyond normal—they want to be superb, to be atypical, to be the outlier. It is irrelevant what the athlete believes or feels. What is relevant is whether the performance is improved, which is a measurable and documented event”. They have described some of the factors that distinguish work with athletes from work with clients which includes intensive transfer of learning training, often between 2 and 6 hours of daily practice across days, weeks, and months. This process is described by the Australian cross-country skier, Janine Shepherd, who had hoped for an Olympic medal — until she was hit by a truck during a training bike ride. She shares a powerful story about the human potential for recovery. Her message: You are not your body, and giving up old dreams can allow new ones to soar.

Increase strength and mood

 “Don’t slouch! How many times do I have to tell you to sit up straight?”

“I couldn’t believe it, I could not think of any positive thoughts while looking down?

Body posture is part of our nonverbal communication; it sometimes projects how we feel. We may collapse when we receive bad news or jump up with joy when we achieve our goal. More and more we sit collapsed for many hours with our spine in flexion. We crane our heads forward to read text messages, a tablet, a computer screen or watch TV. Our bodies collapse when we think hopeless, helpless, powerless thoughts, or when we are exhausted. We tend to slouch and feel “down” when depressed.

We often shrink and collapse to protect ourselves from danger when we are threatened. In prehistoric times this reaction would protect us from predators as we were still prey. Now we may still give the same reaction we worry or respond to demands from our boss. At those moments, we may blank out and have difficulty to think and plan for future events. When the body reacts defensively, the whole body-mind is concerned with immediate survival. Rational and abstract thinking is reduced as we attempt to escape.

When standing tall we occupy more space and tend to project power and authority to others and to ourselves. When we feel happy, we walk erect with a bounce in our step. Emotions and thoughts affect our posture and energy levels; conversely, posture and energy affect our emotions and thoughts. At San Francisco State University, we have researched how posture changes physical strength and access to past memories. Experience this in the following practice (you will need a partner to do this).

How posture affects strength

Stand behind your partner and ask them to lift their right arm straight out as shown in figure 1. Apply gentle pressure downward at the right wrist while your partner attempts to resist the downward pressure. Apply enough pressure downward so that the right arm begins to go down. Relax and repeat the same exercise with the left arm. Then relax.

fig 1 Muscle testing

Figure 1. Experimenter pressing down on the arm while the subject resist the downward pressure

For the rest of this exercise, do the testing with the arm that most resisted to the downward pressure.

Have the person stand in a slouched position and then lift the same arm straight out. Again the experimenter applies enough pressure downward so that the arm begins to go down. Relax.

Then have the person stand a tall position and lift the arm straight out. Again, the experimenter now applies enough pressure downward so that the arm begins to go down. Relax.

Describe to each other how easy it was to resist the downward pressure and how much effort it took to press the arm down while standing tall or slouched.

In our just completed study in the Netherlands with my colleague Annette Booiman, we observed that 98% of the participants felt significantly stronger to resist the downward pressure when they stood in a tall position than when they stood in the collapsed position as shown in Figure 2.

fig 2 perceived muscle strenth graph

Figure 2. The perceived strength to resist the down pressure on the arm in either the erect or collapsed position as observed by the subjects and the experimenters (Exp).

The subjective experience of strength may be a metaphor of how posture affects our thoughts, emotions, hormones and immune system[1]. When slouching we experience less strength to resist and it is much more challenging to project authority, think creatively and successfully solve problem. Obviously, the loss of strength mainly related to the change in the shoulder mechanics; however, the collapsed body position contributes to feeling hopeless, helpless, and powerless.

With my colleague Dr. Vietta Wilson (Wilson & Peper, 2004), we discovered that in the collapsed position it was very difficult to evoke positive and empowering memories as compared to the upright position (for more information see the article by Wilson and Peper: http://biofeedbackhealth.files.wordpress.com/2013/01/the-effects-of-posture-on-mood.pdf).

Consistently, my students at San Francisco State University have reported that when they blank out on exams or class presentations, if they stop for a moment, change their posture and breathe, they can think again. Similarly, clients who are captured by worry and discomfort, when they shift position and look up, find it is easier to think of new options.   Explore for this yourself.

How Posture effect Memory Recall

Sit comfortably at the edge of a chair and then collapse downward so that your back is rounded like the letter C. Let your head tilt forward and look at the floor between your thighs as shown in figure 3.

Fig 3 collapsed sittingFigure 3. Sitting in a collapsed position (photo by Jana Asenbrennerova). Reprinted by permission from Gorter and Peper (2011).

While in this position, bring to mind hopeless, helpless, powerless, and depressive memories one after the other for thirty seconds.

Then, let go of those thoughts and images and, without changing your position and still looking downward, recall empowering, positive, and happy memories one after the other for thirty seconds.

Shift position and sit up erect, with your back almost slightly arched and your head held tall while looking slightly upward as shown in figure 4.

Fig 4 erect sittingFigure 4. Sitting in an upright position (photo by Jana Asenbrennerova). Reprinted by permission from Gorter and Peper (2011).

While is this position, bring to mind many hopeless, helpless, powerless, or depressive memories one after the other for thirty seconds.

Then, let go of those thoughts and images and, without changing position and while still looking upward, recall as many empowering, positive, and happy memories one after the other for thirty seconds

Ask yourself: In which position was it easier to evoke negative memories and in which position was it easier to evoke empowering, positive, and happy memories?

Overwhelmingly participants report that in the downward position it was much easier to recall negative and hopeless memories. And, in the upright position it was easier to recall positive and empowering memories. In many cases, participant reported that when they looked down, they could not evoke any positive and empowering memories. It is not surprising that when people feel optimistic about the future, they say, “Things are looking up.”

Mind and body affect each other. The increase in depression and fatigue may be in part be caused by the body position of sitting collapsed at work, at home and walking a slouched pattern. By shifting body movement and position from slouching to skipping one’s subjective energy may significantly increase (Peper & Lin, 2012) (for more information see: https://peperperspective.com/2012/09/30/take-charge-of-your-energy-level-and-depression-with-movement-and-posture/)

Take charge, lightening your mood and give yourself the opportunity to be empowered and hopeful. When feeling down, acknowledge the feeling and say, “At this moment, I feel overwhelmed, and I’m not sure what to do” or whatever phrase fits the felt emotions. When your energy is low, again acknowledge this to yourself: “At this moment I feel exhausted,” or “At this moment, I feel tired,” or whatever phrase fits the feeling. As you acknowledge it, be sure to state “at this moment.” The phrase “at this moment” is correct and accurate. It implies what is occurring without a self-suggestion that the feeling will continue, which helps to avoid the idea that this was, is, and will always be. The reality is that whatever we are experiencing is always limited to this moment, as no one knows what will occur in the future. This leaves the future open to improvement.

Remind yourself that you to shift your mood by changing your posture. When you’re outside, focus on the clouds moving across the sky, the flight of birds, or leaves on the trees. In your home, you can focus on inspiring art on the wall or photos of family members you love and who love you. When you hang pictures, hang them higher than you normally would so that you must look up. You can also put pictures above your desk to remind yourself to look up and to evoke positive memories.

These two studies point out that psychology needs to incorporate body posture and movement as part of the therapeutic and teaching process. Without teaching how to change body posture only one half of the mind-body equation that underlies health and illness is impacted.

Each time you collapse or have negative thoughts, change your position and sit up and look up. Arrange your world so that you are erect (e.g., stand while working at the computer, use a separate keyboard with your laptop so that the top of the screen is at eye level, or place a pillow in your lower back when sitting). Finally, every so often, get up and move while alternately reach up with your arms into the sky as if picking fruits which you can not quite reach.

After having done these two practices, I realized how powerful my body effects my mood and energy level. Now each time I am aware that I collapse, I take a breath, shift my position, look up, and often stand up and stretch. To my surprise, I have so much more energy and my negative depressive mood has lifted.

Screens will hurt your children

We park children in front of tablets, smartphone, computers and TVs.  The visual and auditory stimulation captures their attention. It is a superb baby sitter.  We substitute electronic displays for human attention.

baby

To distract the baby at dinner in a restaurant, we hand the baby a smartphone.   To have some private time, we let the child play games on the tablet.  To reduce stress before dinner, we hand the child the tablet to watch video clips or play games. The short term benefits of letting handheld devices capture the child’s attention may have long term costs.

The child sits, sits and sits while being captured by the rapid changing visual scenes and auditory sounds instead of playing and enhancing motor development.  The addictiveness of electronic devices occurs because we automatically attend to and are captured by rapidly changing stimuli—it is new and could be dangerous. This reaction to attend which is continuously evoked by the handheld devices may occur at the expense of developing self-directed attention.

The handheld devices expose the brain and dividing cells to electromagnetic radiation which can harmful. This is the radiation by which hand held devices communicates with connect cell phone towers or the server as it connects to the web.

From the precautionary principle and the numerous research studies, young children should limit the use of hand held devices. I totally agree with Cris Rowan’s superb blog, 10 Reasons Why Handheld Devices Should Be Banned for Children Under the Age of 12, which is reprinted below with her permission.

10 Reasons Why Handheld Devices Should Be Banned for Children Under the Age of 12

Cris Rowan pediatric occupational therapist, biologist, speaker, author

The American Academy of Pediatrics and the Canadian Society of Pediatrics state infants aged 0-2 years should not have any exposure to technology, 3-5 years be restricted to one hour per day, and 6-18 years restricted to 2 hours per day (AAP 2001/13, CPS 2010). Children and youth use 4-5 times  the recommended amount of technology, with serious and often life threatening consequences (Kaiser Foundation 2010, Active Healthy Kids Canada 2012). Handheld devices (cell phones, tablets, electronic games) have dramatically increased the accessibility and usage of technology, especially by very young children (Common Sense Media, 2013). As a pediatric occupational therapist, I’m calling on parents, teachers and governments to ban the use of all handheld devices for children under the age of 12 years. Following are 10 research-based reasons for this ban. Please visit zonein.ca to view the  Zone’s Fact Sheet for referenced research.

1. Rapid brain growth
Between 0 and 2 years, infant’s brains triple in size and continue in a state of rapid development to 21 years of age (Christakis 2011). Early brain development is determined by environmental stimuli or lack thereof. Stimulation to a developing brain caused by overexposure to technologies (cell phones, internet, iPads, TV), has been shown to be associated with executive functioning and attention deficit, cognitive delays, impaired learning, increased impulsivity and decreased ability to self-regulate e.g. tantrums (Small 2008, Pagini 2010).

2. Delayed Development
Technology use restricts movement, which can result in delayed development. One in three children now enter school developmentally delayed, negatively impacting literacy and academic achievement (HELP EDI Maps 2013). Movement enhances attention and learning ability (Ratey 2008). Use of technology under the age of 12 years is detrimental to child development and learning (Rowan 2010).

3. Epidemic Obesity
TV and video game use correlates with increased obesity (Tremblay 2005). Children who are allowed a device in their bedrooms have 30% increased incidence of obesity (Feng 2011). One in four Canadian, and one in three U.S. children are obese (Tremblay 2011). 30% of children with obesity will develop diabetes, and obese individuals are at higher risk for early stroke and heart attack, gravely shortening life expectancy (Center for Disease Control and Prevention 2010). Largely due to obesity, 21st century children may be the first generation many of whom will not outlive their parents (Professor Andrew Prentice, BBC News 2002).

4. Sleep Deprivation
60% of parents do not supervise their child’s technology usage, and 75% of children are allowed technology in their bedrooms (Kaiser Foundation 2010). 75% of children aged 9 and 10 years are sleep deprived to the extent that their grades are detrimentally impacted (Boston College 2012).

5. Mental Illness
Technology overuse is implicated as a causal factor in rising rates of child depression, anxiety, attachment disorder, attention deficit, autism, bipolar disorder, psychosis and problematic child behavior (Bristol University 2010, Mentzoni 2011, Shin 2011, Liberatore 2011, Robinson 2008). One in six Canadian children have a diagnosed mental illness, many of whom are on dangerous psychotropic medication (Waddell 2007).

6. Aggression
Violent media content can cause child aggression (Anderson, 2007). Young children are increasingly exposed to rising incidence of physical and sexual violence in today’s media. “Grand Theft Auto V” portrays explicit sex, murder, rape, torture and mutilation, as do many movies and TV shows. The U.S. has categorized media violence as a Public Health Risk due to causal impact on child aggression (Huesmann 2007). Media reports increased use of restraints and seclusion rooms with children who exhibit uncontrolled aggression.

7. Digital dementia
High speed media content can contribute to attention deficit, as well as decreased concentration and memory, due to the brain pruning neuronal tracks to the frontal cortex (Christakis 2004, Small 2008). Children who can’t pay attention can’t learn.

8. Addictions
As parents attach more and more to technology, they are detaching from their children. In the absence of parental attachment, detached children can attach to devices, which can result in addiction (Rowan 2010). One in 11 children aged 8-18 years are addicted to technology (Gentile 2009).

9. Radiation emission
In May of 2011, the World Health Organization classified cell phones (and other wireless devices) as a category 2B risk (possible carcinogen) due to radiation emission (WHO 2011). James McNamee with Health Canada in October of 2011 issued a cautionary warning stating “Children are more sensitive to a variety of agents than adults as their brains and immune systems are still developing, so you can’t say the risk would be equal for a small adult as for a child.” (Globe and Mail 2011). In December, 2013 Dr. Anthony Miller from the University of Toronto’s School of Public Health recommend that based on new research, radio frequency exposure should be reclassified as a 2A (probable carcinogen), not a 2B (possible carcinogen). American Academy of Pediatrics requested review of EMF radiation emissions from technology devices, citing three reasons regarding impact on children (AAP 2013).

10. Unsustainable
The ways in which children are raised and educated with technology are no longer sustainable (Rowan 2010). Children are our future, but there is no future for children who overuse technology. A team-based approach is necessary and urgent in order to reduce the use of technology by children. Please reference below slide shows on www.zonein.ca under “videos” to share with others who are concerned about technology overuse by children.
