Hydrogen comes in two “flavors”: regular hydrogen, which is actually called protium, and deuterium. Deuterium has all of the same properties as hydrogen, except that it's twice as big and heavy. This is due to an added neutron paired with the proton in the nucleus. Because of this, deuterium is also referred to as "heavy hydrogen," and it actually behaves quite differently from regular hydrogen in chemical reactions and in our bodies.

In nature, deuterium helps things grow. For example, deuterium is biologically necessary for growth in babies, teenagers, and developing plants and animals. But once you stop growing, having too much deuterium in your cells can result in mitochondrial dysfunction and lead to premature aging, metabolic problems, and disease.

Deuterium is like thick, gluggy oil  - when you put thick oil into an engine, the engine sputters, makes strange noises, and eventually breaks.


Nature has put systems in place to deplete deuterium and protect the nanomotors, or "little engines," in our cells’ mitochondria from coming into contact with this thick oil.


However, the side effects of a modern life - pollution, global warming, processed foods, less healthy lifestyles, etc. - have resulted in many people having way too much deuterium inside their cells. This results in an inability to effectively deplete deuterium and the destruction of our nanomotors.


This starts a vicious cycle of deuterium building up and breaking more of our nanomotors. Fewer nanomotors means less energy and more sickness and disease.

While deuterium is a natural and essential element, its presence has increased in the modernized environment within the food, atmosphere, and water. Deuterium levels is food will vary based o where that food is grown - deuterium is highest in the equator and in low elevations. Foods high in fat, as well as green plants, including algae and spirulina, which contain high amounts of chlorophyll, are lower in deuterium than fruits, roots, and underground vegetables. As it turns out, GMO foods tainted with glyphosate, as well as processed, synthetically made foods, possess high amounts of deuterium.

There are various lifestyle practices that have led to increased deuterium levels including a lack of sleep, particularly deep REM sleep. In addition, breathing shallow and fast via the mouth and chest also contributes to elevated levels of deuterium.

Researchers have demonstrated that elevated of deuterium can contribute to:

• Chronic fatigue
• Diminished deep and REM sleep
• Anxiety and depression
• Increased aging, leading to to diseases like diabetes, cardiovascular disease, and Alzheimer's
• Increased cancer cell growth
• Immune dysregulation

Over the course of the past century, the Western culture has faced numerous health epidemics, from obesity to opioids. Today we are facing an epidemic of a different nature. The epidemic of loneliness.

We're more connected than ever, but are we feeling more alone? In the last 50 years, rates of loneliness have doubled in the United States. In a survey of over 20,000 American adults, it was found that almost half of respondents reported feeling alone, left out, and isolated. Further, one in four Americans shared that they rarely feel understood, and one in five people believe they rarely or never feel not close to people. Loneliness is on the rise for Americans regardless of geographic location, gender, race, or ethnicity.

Human beings did not evolve to be alone. Sociality plays a fundamental part in the wellbeing of Homo sapiens. Conversely, social isolation and loneliness are known risk factors for premature death, more so than being obese (Holt-Lunstad et al., 2015). Individuals who feel socially isolated and alone also have higher rates of cardiovascular disease, alcoholism and suicidality, physical diseases related to stress and compromised immune function, and in later life, greater risk of degenerative dementia. Even worse, researchers have observed that geriatric individuals who are considered lonely have a 45% increased risk of mortality (Leland, 2012; Perissinotto, Stijacic Cenzer and Covinsky, 2012). 

Moreover, lonely individuals experience reductions in reasoning and creativity. In addition to these reduced abilities, loneliness affects workplace productivity, as lonely individuals report less job satisfaction and are more likely to face unemployment. Not surprisingly, loneliness is commonly correlated with mental health concerns such as anxiety and depression. Similarly, loneliness is often associated with poor coping mechanisms, such as compulsive technology use, smoking, and self-harm. In other words, loneliness has both physical and psychological implications, many of which could be long term.

Before determining yourself as lonely, there is a difference between being alone and feeling lonely. Being alone and feeling lonely are not mutually dependent. Loneliness is a subjective experience, a feeling of sadness stemming from isolation or abandonment. But, a person can be alone without feeling lonely, since alone describes a state of being and lonely describes an emotional response to one's circumstance. For example, most people don't feel sad when they go to the restroom by themselves. A person can be alone in the sense that no other people are present, or alone in the sense that they are unaccompanied, even in a crowd.

When assessing loneliness, introverted and extroverted personalities should be taken into account, because some people enjoy the presence of being alone with themselves, whereas others are dependent on others to cope with not being by themselves. Being at either end of the spectrum, whether it is total isolation or complete dependence, is not considered a healthy behavioral pattern.

The predictors of loneliness is the basis for the identification of factors that cause and contribute to loneliness. The are three broad categories that influence the feeling of loneliness:

• problems with relationships;
• traumatic experiences;
• and, personal and developmental variables.

  
These categories may be subdivided into multiple factors that increase loneliness:

1. Personality: There are several personality factors that contribute to loneliness, including but not limited to, anxiety, an inability to assert oneself, and hyper-sensitivity. A victim mentality, a poor self concept, an external locus of control and shyness are other aspects of the personality that contribute to loneliness.
   
2. Affect: Loneliness is linked to negative affect and is typified in conditions such as depression, boredom, hopelessness, aggression, stress, anger, restlessness and tension.
3. Depression: A complicated vicious circle makes diagnosis tricky: people with poor social skills are more inclined to become depressed and yet depressed people are inclined to be lonely. There is a difference between depression and loneliness.
4. Problems in relationships: A lack of feelings of belonging, support and intimacy caused by poor communication promote loneliness. Social estrangement and separation and rejection also contribute to loneliness.
5. Marital status: Married people usually feel less lonely - but this is not the case when marriages are unfulfilling. Loneliness in marriage is linked to a lack of intimacy. Major changes that promote social isolation consist of events such as leaving home, a new career, separation from loved ones, breaking off a major relationship and moving house.
6. Illness or physical disability may lead to limited contact with other people.
7. Religious faith: Religions with strict behavioral prescriptions are likely to isolate individuals from free social interaction, potentially resulting in loneliness.
8. Academic achievement: Researchers have observed that students whose academic performance is poor are more likely to be lonely.
9. Leisure activities that alienate people from each other are watching television and surfing the Internet.

While it is impossible to avoid loneliness completely, it may be alleviated. It is recommended to investigate the contributory factors towards loneliness because knowledge of these may substantially lessen the impact of loneliness on people's mental health status. Such knowledge will contribute to an improved quality of life, productivity and health.

The "loneliness phenotype" can be triggered by sleep deprivation. Researchers have observed that a lack of sleep induces critical changes within the brain, altering behavior and emotions, while also disturbing essential metabolic processes and influencing the expression of immune-related genes. The end result is that people who are sleep-deprived avoid social interaction. This asocial profile is recognizable by other people, who, in turn, shun the sleep-deprived people in a psychosocial loop that perpetuates in a vicious cycle of loneliness and other mental health disorders.

What is the fastest way to health? It's simply honesty being honest with yourself. We each have four doctors within ourselves: Dr. Happiness, which is what is our concept of what makes us happy (what am you living for?); Dr. Quiet which is how do you create adequate rest to regenerate yourself to have a clear mind and to let my body recover from any stress; Dr. Diet (how do you tune into your body's particular nutritional needs?); and Dr. Movement, which is the difference between Working Out and Working In and putting those movement types to use in your life.

Have you ever wondered what the health impact of a stressful day was? Will you perform well during your long run or training session tomorrow morning? Is there anything you can do today that would improve your ability to have a better day tomorrow? HRV may be a piece of data that could help you answer these questions.

HRV is simply a measure of the variation in time between each heartbeat, also known as the RR interval. This variation is controlled by a primitive part of the nervous system called the autonomic nervous system (ANS). The ANS works regardless of our desire and regulates, among other things, our heart rate, blood pressure, breathing, and digestion. The ANS is subdivided into two large components, the sympathetic and the parasympathetic nervous system, also known as the fight-or-flight mechanism and the relaxation response.

The brain is constantly processing information in a region called the hypothalamus. The hypothalamus, through the ANS, sends signals to the rest of the body either to stimulate or to relax different functions. It responds not only to a poor night of sleep, or that sour interaction with your boss, but also to the exciting news that you got engaged, or to that delicious healthy meal you had for lunch. Our body handles all kinds of stimuli and life goes on. However, if we have persistent instigators such as stress, poor sleep, unhealthy diet, dysfunctional relationships, isolation or solitude, and lack of exercise, this balance may be disrupted, and your fight-or-flight response can shift into overdrive.

HRV is a noninvasive way to identify these ANS imbalances. If a person’s system is in more of a fight-or-flight mode, the variation between subsequent heartbeats is low. If one is in a more relaxed state, the variation between beats is high. In other words, the healthier the ANS the faster you are able to switch gears, showing more resilience and flexibility. Over the past few decades, research has shown a relationship between low HRV and worsening depression or anxiety. A low HRV is even associated with an increased risk of death and cardiovascular disease (Buccelletti et al., 2009; Tsuji et al., 1994).

People who have a high HRV may have greater cardiovascular fitness and be more resilient to stress. HRV may also provide personal feedback about your lifestyle and help motivate those who are considering taking steps toward a healthier life. It is fascinating to see how HRV changes as you incorporate more mindfulness, meditation, sleep, and especially physical activity into your life. For those who love data and numbers, this can be a convenient way to track how your nervous system is reacting not only to the environment, but also to your emotions, thoughts, and feelings.

The gold standard to measure HRV is to analyze a long strip of an electrocardiogram, the test that occurs frequently in medical offices where wires are attached to the chest. But over the past few years, several companies have created heart rate monitors that sync with apps that do something similar. The accuracy of these methods is still under scrutiny, but the technology is improving substantially. A word of caution is that there are no agencies regulating these devices, thus they may not be as accurate as claimed to be. With that said, the easiest and cheapest way to check HRV is to buy a chest strap heart monitor (e.g., Polar H10) and download a free app (e.g., Elite HRV) to analyze the data. The chest strap monitor tends to be more accurate than wrist or finger devices. Check your HRV in the mornings after you wake up, a few times a week, and track for changes as you incorporate healthier interventions.

Tracking HRV may be a great tool to motivate behavioral change for some. HRV measurements can help create more awareness of how you live and think, and how your behavior affects your nervous system and bodily functions. While it obviously can’t help you avoid stress, it could help you understand how to respond to stress in a healthier way. While there are questions about measurement accuracy and reliability, if you decide to use HRV as another piece of data, do not get too confident if you have a high HRV, or too scared if your HRV is low. Think of HRV as a preventive tool, a visual insight into the most primitive part of your brain.

Far from the metronome we might assume it to be, the healthiest heart beat follows a fractal pattern, with varying lengths of time separating each pulse (Tapanainen et al., 2002; Yaniv, Y., Lyashkov, A. E., Lakatta, E. G., 2013). A higher HRV suggests a relaxed, low-stress physiological milieu, while a lower HRV indicates a need for recovery, rest, and sleep. Therefore, in order to increase HRV, generally speaking, a more relaxed, low-stress environment is desirable. While there are a number of ways to reduce stress and increase relaxation, here are some examples that have been observed to increase HRV:

• Allocate time for rest
• Drink green tea (or take L-theanine) (Fiorino et al., 2012)
• Don't procrastinate (Dimitriev, Dimitriev, Karpenko, & Saperova, 2008; Tharion, E., Parthasarathy, S., & Neelakantan, N., 2009)

• Reduce commuting time and overtime (Kageyama et al., 1998)
• Work a job with a high reward to work ratio (Hintsanen et al., 2007; Loerbroks et al., 2010)
  
• Practice forgiveness (Patel, 2013)
  
• Practice yoga (Patil et al., 2013; Tyagi & Cohen, 2016)
• Practice meditation (Krygier et al., 2013; Nesvold et al., 2011)
• Listen to calm, relaxing music (Da Silva, 2014; Valenti et al., 2013)
• Breathe deeply and slowly (Török, T., Rudas, L., Kardos, A., Paprika, D., 1998)
• Try forest bathing (Lee et al., 2011)
• Consume omega-3 fatty acids (Sauder et al., 2013)

Physiologically, fasting:

• Stabilizes blood sugar
• Reduces insulin levels and improves insulin resistance
• Recovers and regenerates the gastrointestinal and immune system
• Increases ketone production
• Increases metabolic rate
• Removes damaged cells
• Reduces hunger
• Reduces excess body fat
• Reduces level of hormones thought to promote cancer
• Reduces the rate of aging
• Sheds excess body fat
• Protects brain function

The only other strategy that has so many research-baked benefits for longevity is long-term calorie restriction, which requires a significant long-term reduction in the amount of food you eat so that you are essentially living on the brink of starvation. Compliance with calorie-restricted diets is abysmal. Fortunately, there are many ways to fast, and there is likely a form of fasting out there that you will be able to tolerate and incorporate into your life. It's important for you to remember that fasting can provide nearly identical benefits without the pain, suffering, and compliance challenges of calorie restriction.

Instead of regulating how much food you eat, as with long-term calorie restriction, you only need to modify when you eat - and of course wisely choose the foods you do eat.Simply cycling between periods of eating and fasting on a daily, weekly, or monthly schedule has been shown to provide many of the same benefits as long-term calorie restriction. Choosing when to eat and when to fast in this way is known as "intermittent fasting."

Intermittent fasting is rapidly growing in popularity for the simple reason that it works. It does so whether you're trying to loss excess body fat or improve biofeedback for optimal health. As a general rule, intermittent fasting involves cutting calories, in whole or in part, either a couple of days a month or a week, every other day, or even daily.
 
There are many ways to fast, from consuming nothing but water for two to three days each month to eating a normal amount of calories every day but during a restricted window of time so you still get a good long stretch without food intake during each 24-hour period.

Here's a brief overview of a couple of different options:

2- to 3-Day Water Fast
It is generally not recommended to go without food for any period longer than about 18 hours. However, if you are overweight and have serious health challenges, a medically supervised water fast may be appropriate.

A water fast consists of consuming nothing but water and some minerals for a finite period of time. This type of fast can give you a shorter transition into fat burning because the body will rapidly burn through glycogen stores and begin using fat for energy.

This fast may be appropriate if you have just received a very serious diagnosis, such as brain cancer. Although if you are limited by any of the following conditions, consult with your health care practitioner before embarking of this type of fast:

• Already underweight
• Nutritionally compromised
• Taking diuretics or blood pressure medications
• Have low blood pressure
• Have diabetes, thyroid disease, chronically low sodium levels, or cardiovascular disease

5-Day Fast
This fast consists of spending five consecutive days of each month on a modified fast. You do not abstain from food entirely during these days. On the first day, you eat about 1,000 to 1,100 calories, followed by 725 calories on the remaining four days. As with all fasting options, the foods you do eat should be low in net carbohydrates and protein, and high in healthy fats.

Researchers have observed when people who have fasted five consecutive days once a month for three consecutive months saw improvements in biomarkers for cell regeneration. Risk factors for diabetes, cancer, cardiovascular disease., and aging also declined (Brandhorst et al., 2015).

Beware that is can be quite challenging to go for a full five days with very little food, especially if you've never fasted before, so you may want to work your way up slowly to this type of fast. Remember, "low and slow."

1-Day Fast
With this fast, you skip eating for one day of every week, consuming only water on that day. Your fast should be broken with a regular-sized meal, and you can maintain your regular exercise program without any special diet recommendations for workout days.

Fasting for 24 hours can be rough for some people, but eating a high-fat low-carb diet can make a 24-hour fast easier, as a higher fat diet will tend to normalize your hunger hormones and provide improved satiety for longer periods of time. You can also fast from dinner to dinner, skipping a full 24 hours of eating while still eating each day.

Alternate-Day Fasting
This program consists of eating on one day, and not eating on the next. During fasting days you restrict your eating to one meal of about 500 calories. On nonfasting days, you can eat normally.

When you include sleeping time, your fast can end up being as long as 32 to 26 hours. According to Krista Varady, Ph.D., author of The Every-Other-Day Diet, alternate-day fasting can help you lose up to two pounds of body fat per week.

Another benefit to alternate-day fasting is that your body tends to adapt to the regularity of the program. In clinical trials, about 90% of participants were able to stick to alternate-day fasting, whereas the other 10% dropped out within the first two weeks.

Peak Fasting
This form of fasting is by far the easiest to maintain once your body has shifted over from burning sugar to burning fat as its primary fuel, and it also appears to support steady circadian rhythms.

Peak Fasting is done every day rather than a few days per week or month. However, you can certainly cycle in off days to suit your schedule or social commitments - this flexibility is another major benefit of Peak Fasting. If circumstances allow, it is recommended implementing this type of fasting about five days a week. The process is quite simple.

The crux of Peak Fasting is to restrict your eating each day to a 6- to 11-hour window. As a result you will avoid eating for 13 to 18 hours every day. The simplest way to implement this type of fasting is to stop eating at least three hours before bed and then delay your first meal of the following day until at least 13 hours have passed since you last ate.

This may seem like an awfully long time to go without eating on a daily basis, but once you have transitioned to burning fat as your primary fuel, you won't experience those frequent hunger pains. Another benefit of Peak Fasting is that you will be able to go hours without a dip in energy because fat provides a continuous source of fuel. This is in contrast to glucose, which triggers glucose/insulin spikes, frequent hunger pains, and energy crashes as cues to consume more high-carb foods.

Regardless of the fasting program you choose, or even if you choose not to adapt any formal type of fasting, you should stop eating at least three hours before you go to bed. This simple change can help optimize your mitochondrial function and prevent cellular damage. Many factors influence why you will reap health benefits if you develop the habit of not eating within three hours of bedtime:

• When you are sleeping, your energy needs are at their lowest, and providing excess fuel at this time will result in the production of excessive amounts of damaging free radicals.
• Sleep is your body's time for detox and repair, and needing to digest a meal during sleep will impair these important processes.
• Nighttime is a common time for your body to use ketones for energy, since glycogen stores are typically depleted within 18 hours (13 hours if you are eating low quantities of carbohydrates), and eating too close to bedtime can replenish glycogen stores and prevent the body from burning fat for overnight fuel.
• Not eating for at least three hours before bed enables you to extend that period of time without eating food on a daily basis.

A compilation of scientific literature published in 2011 provides much of the experimental work supporting the advice from eating too close to bedtime. The message is clear: since the body uses the least amount of calories when sleeping, eating close to bedtime adds excess fuel which will generative excessive free radicals that will damage the tissues, accelerate aging, and contribute to chronic disease (Pamplona, 2011).

Although intermittent fasting, particularly Peak Fasting, is a powerful way to improve your physiological function all the way down to the mitochondrial level, it is not for everyone. Individuals taking medications, especially those with diabetes, need medical supervision; otherwise there is a risk of hypoglycemia.

If you have serious adrenal challenges or chronic renal disease, are living with chronic stress (adrenal fatigue), or have cortisol dysregulation, you would likely need to resolve these issues before implementing intermittent fasting. Also, if you have a disease called porphyria, you should not fast.

If you goal is to build large muscles or engage in competitive sports such as sprinting that require glucose for anaerobic fast twitch muscle fibers, intermittent fasting is not likely to be your best strategy.

Pregnant women and nursing mothers should not practice intermittent fasting, as the baby needs a wider range of nutrients during and after birth.

Children under 18 should also not fast for extended periods. Moreover, anyone of any age with concerns of malnutrition, or who is underweight (with a BMI less than 18.5), or who has an eating disorder such as anorexia nervosa should avoid fasting.

When implementing intermittent fasting, keep your eye on any signs of hypoglycemia, or low blood sugar, which include:

• Light-headedness
  
• Shakiness
  
• Confusion
  
• Fainting
  
• Excessive sweating
  
• Blurred vision
  
• Slurred speech
  
• Feelings of an atypical heartbeat
  
• Pins and needles sensation (neuropathy) in the fingertips
  

If you suspect that your blood sugar is low, make sure to eat something that will not impact your blood glucose levels, such as foods with a lower glycemic index quantity, including coconut oil in black coffee or tea.

The most challenging part of any intermittent fasting plan is getting through the initial transition, which can take anywhere from a week to two months. In some people this transition may take even longer, depending on how insulin resistant they are and other factors such as weight, blood pressure, and how consistent they are with their fasting regimen.

Roughly 10% of people report headaches as a side effect when they first begin fasting, but the biggest complaint is hunger. This is why it is so important to remain hydrated, especially while adding extra magnesium. It may be helpful to remember that one reason you're craving food is because your body has not yet made the switch from burning sugar to burning fat as its primary fuel. As long as you're running on sugar, frequent hunger pains will be the norm. Fat is far more satisfying, as it's a much slower-burning fuel.

Another factor that can cause disruption during the transition period is purely psychological. If you're used to grazing in the evenings, it may take some time to break the habit. One trick is to make it easier to go longer periods of time without eating is to drink more water. Oftentimes people mistake thirst for hunger.

It typically takes a few days to work up to 13 hours of fasting, but once you start activating your fat-burning system you will easily achieve this. The most effective way is to keep to your fat-burning plan by limiting your net carbs to under 40 grams per day and not exceeding more than 1 gram of protein per kilogram of lean body mass.

Humans are ancient beings living in a modern world. We have been hard-wired through evolution to require and seek contact with nature. A healthy, balanced life, physically and emotionally, requires this contact. Exposure to nature is one of the key foundations to a meaningful life. Indeed, a growing body of evidence overwhelmingly suggests connecting with nature is paramount for optimal health. 

Connection with nature has been associated with:

• Enhanced cognitive functioning
  
• Creativity and problem solving skills
  
• Reduced anxiety and stress
  
• Reduced blood pressure
  
• Stronger immune system
  
• Improved mental health
  
• Deeper sleep
  
• Enhanced feeling of wellness
  

How much exposure to nature and outdoor natural environments is necessary, though, to ensure healthy development? Are there such things as minimum daily requirements of nature?

Determining a daily dose of exposure to nature is comparable to the nutrition pyramid that has been touted as a useful guide for the types and quantity of food consumption necessary to be healthy. It has been dubbed the Nature Pyramid,.

Referring to the standard nutritional pyramid, towards the top are things that are less healthful in larger quantities—meat, dairy, sugar—and should be consumed in the smallest proportions. Moving down the pyramid are elements in the diet—fruits and vegetables—that should be consumed more frequently and in greater quantity, and then finally the foods that contain the most nutrients that are needed on a daily basis. The Nature Pyramid would work in a similar way.

The Nature Pyramid challenges us to think about what the analogous quantities of nature are, and the types of nature exposures and experiences, needed to bring about a healthy life. Exposure to nature, that is direct personal contact with natural, is not an optional thing, but rather is a necessary and important element of a healthy human life. So, like the nutritional pyramid, what specifically is required for optimal health? What amounts of nature, different nature experiences, and exposure to different sorts of nature, together constitute a healthy existence? While researchers may lack the same degree of scientific certainly or confidence regarding a specific quantifiable amount of connection with nature necessary to ensure a healthy life, the pyramid at least begins to ask the right questions.

In 2005, in Last Child in the Woods, Richard Louv introduced the term nature-deficit disorder, not as a medical diagnosis, but as a way to describe the growing gap between humans and nature. Every day, our relationship with nature, or the lack of it, influences  our lives. This has always been true. But in the twenty-first century, our survival — or thrival — will require a transformative framework  for that relationship, a reunion of humans with the rest of nature.

The Nature  Principle is an amalgam of converging theories and trends as well as a  reconciliation with old truths. This principle holds that a reconnection to the natural world is fundamental to human health, wellness,  spirit, and survival. Primarily a statement of philosophy, the Nature Principle is supported by a growing body of theoretical, anecdotal, and empirical  research that describes the restorative power of nature  —   its impact  on our senses and intelligence; on our physical, psychological, and  spiritual health; and on the bonds of family, friendship, and the multispecies community.  What would our lives be like if our days and  nights were as immersed in nature as they are in electronics? How can each of us help create that life-enhancing world, not only in a hypothetical future, but right now, for our families and for ourselves? 

Our sense of urgency grows. In 2008, for the first time in history, more than half of the world’s population lived in towns and cities. The traditional ways that humans have experienced nature are vanishing, along with biodiversity. At the same time, our culture’s faith in technological immersion seems to have no limits, and we drift ever deeper into a sea of circuitry.  We consume breathtaking media accounts of the creation of synthetic  life, combining bacteria with human DNA; of microscopic machines designed to enter our bodies to fight biological invaders or to move in deadly clouds across the battlefields of war; of virtually-augmented reality; of futuristic houses in which we are surrounded by simulated reality transmitted from every wall. We even hear talk of the “transhuman” or “posthuman” era in which people are optimally enhanced by  technology, or of a “postbiological universe” where, as NASA’s Steven Dick puts it, “the majority of intelligent life has evolved beyond flesh  and blood intelligence.”

This collective disorder threatens our health, our spirit, our economy, and our future stewardship of the environment. Yet, despite what seem prohibitive odds, transformative change is possible. The loss that we feel, this truth that we  already know, sets the stage for a new age of nature. In fact, because of  the environmental challenges we face today, we may be  —   we had better  be  —   entering the most creative period in human history, a time defined  by a goal that includes but goes beyond sustainability to the renaturing of everyday life.

Do you or does someone you know experience nature-deficit disorder (NDD)? In this day in age, it is common to develop mild or severe forms of NDD. Here are several symptoms to look out for:

• Distraction - Foggy-headed and unfocused, distraction is a major symptom of NDD. Over-stimulated by tethered media devices and buzzing technologies, our attention-spans are being challenged more and more.
• Stress and Anxiety - Bogged down by endless todo lists? Does your work and daily life make it hard to slow down? Exhausted by our own agendas, we forget to take time to breathe. As a result, our bodies can experience varying symptoms from lack of sleep to high-blood pressure.     
  
• Depression - If you’ve ever had the winter blues, you know Seasonal Affective Disorder exists. Due to reduced sunlight and our sleeping patterns getting out of whack, we experience SAD. Combined with SAD, NDD may bring about depression in some, although it’s not always a visible symptom.  
• Obesity - Constantly indoors, our bodies can gain a few pounds and easily become overweight. What’s worse, obesity can lead to an endless list of other health-related issues.  The American Heart Association (AHA) gave a recent report that one in three children are considered overweight. Exceeding even drug abuse and smoking as a top health risk concern among parents, childhood obesity comes with added issues into adulthood: Type 2 diabetes, elevated cholesterol levels, higher blood pressures, lower self-esteem, and depression, among a few.     
  

At the bottom of the pyramid are forms of nature and outside life that should form the bulk of our daily experiences. Here there are the many ways in which we might daily enjoy and experience nature, both suburban and urban. As adults, a healthy nature diet requires being outside at least part of each day, walking, strolling, sitting, though it need not be in a remote and untouched national park or otherwise more pristine natural environment. Brief experiences and brief episodes of respite and connection are valuable to be sure: watching birds, hearing the outside sounds of life, and feeling the sun or breeze on one’s arms are important natural experiences, though perhaps brief and fleeting. Some of these experiences are visual and we know that even views of nature from office or home windows provides value. For school aged kids spending the day in a school drenched in full spectrum nature daylight is important and we know the evidence is compelling about the emotional value of this. Every day kids should spend some time outside, sometime playing and running outside, in direct contact with nature, weather, and the elements.

Moving from the bottom to the top of the pyramid also corresponds to an important temporal dimension. We need and should want to visit larger more remote parks and natural areas, but for most of us the majority of these larger parks will not be within distance of a daily trip. Each week, we should seek out a local park or area larger than your backyard. Each month, we should seek out a larger, national park. At the top of the pyramid are places and nature experiences that are profoundly important and enriching yet are more likely to happen less frequently, such as remote verdant areas, perhaps only several times a year. They are places of nature where immersion is possible, and where the intensity and duration of the nature experience are likely to be greater. And in between these temporal echelons (from daily to yearly) lie many of the nature opportunities and experiences that happen often on weekends or holidays or every few weeks, and perhaps without the degree of regularity that daily neighborhood nature experiences provide.

Like the food items higher on the food pyramid, the sites of nature highest on the Nature Pyramid might best be thought of occasional treats in our nature diet—good for us in small and measured servings, but actually unhealthy if consumed too often or in too great a quantity. For many urbanites from industrialized nations, large amounts of money and effort are expended visiting remote areas, from Patagonia, to the cloud forests of Costa Rica, to the Himalayas. It seems we relish and celebrate the ecologically remote and exotic. While they are deeply enjoyable nature experiences, to be sure, they come at a high planetary cost, as the energy and carbon footprint associated with jetting to these places is large indeed. No longer are such trips appreciated as unique and special “trips of a lifetime,” but fairly common and increasingly pedestrian jaunts to the affluent citizenry of the North. The Nature Pyramid sends a useful signal that travel to faraway nature may as glutinous and unhealthy as eating at the top of the food pyramid.

Forest bathing—or Shinrin-yoku Forest Therapy—is a Japanese healing method that allows an individual to immerse in the forest’s atmosphere. It stills the mind, leaving bathers focused and more alert. Researchers have observed that evergreen trees secret a natural chemical called phytoncide, which directly reduced stress levels and boosted immune systems in subjects (Li, 2009).

Researchers (Hansen, Jones and Tocchini, 2017) have determined with the healing components of Shinrin-yoku specifically hones in on the therapeutic effects on:

• the immune system function (increase in natural killer cells/cancer prevention);
• cardiovascular system (hypertension/coronary artery disease);
• the respiratory system (allergies and respiratory disease);
• depression and anxiety (mood disorders and stress);
• mental relaxation (Attention Deficit/Hyperactivity Disorder) and;
• human feelings of “awe” (increase in gratitude and selflessness)

More than 2000 references on the biological responses to radio frequency (RF) and microwave radiation, published up to June 1971, have been documented. Devices that emit RF and microwave radiation include, but is not limited to, cellphones, two-way radios, Wi-Fi routers, cellphone towers, smart watches, bluetooth devices, Smart meters, cordless cell phone base stations, wireless baby monitors, microwave ovens, and any WiFi-connected smart devices that receives and transmits data. Particular attention has been paid to the effects on man of non-ionizing radiation at these frequencies.

Given that neural plasticity is at its greatest during infancy and toddlerhood, sleep is likely to have the most impact on the brain and on cognition during this critical period of early development. Yet, around 20–30% of young children experience problems with sleep. Researchers have observed that even though some infants with atypical sleep patterns early on eventually develop typical patterns of sleep by 6 or 7 years of age, reduced sleep duration in the first two years of life may have long-term consequences on later developmental outcomes, such as some degree of impaired physical, emotional and social functioning. A growing body of evidence suggests that children and adolescents displaying sleep difficulties or irregular bedtime is significantly associated with later problems of mental and physical health and lower cognitive and academic performance (Hill, Hogan, & Karmiloff-Smith, 2007; Kelly, Kelly, & Sacker, 2013; Magee, Gordon, & Caputi, 2014; Lam, Hiscock, & Wake, 2003; Wake, et al., 2006).

For infants and toddlers, touchscreen devices offer an attractive source of stimulation, and their portability allows for a wide range of use across multiple settings. However, the widespread use of devices in this age group has raised serious concerns for parents, educators and policy makers, as the potential impact of touchscreen use on toddler development, such as sleep, remains unknown. In addition, research into the long-term impact of poor sleep during early development remains limited. Yet, findings so far coincide, linking shorter sleep duration to negative developmental outcomes. The majority of studies (~90%) show a consistent pattern linking increased screen time with shorter total sleep time and delayed bedtime. As a result, recent guidelines have recommended screens to be kept out of a child’s bedroom specifically because of the potential impact they may have on sleep (OfCom, 2014).

Given the evidence that:

1. media use is linked to poor sleep in older children and adults,
2. touchscreen use in infants/toddlers is highly prevalent, and
3. sleep plays a prominent role in early cognitive and brain development,

it is critical to investigate whether touchscreen use is associated with sleep problems early in development.

A recent meta-analytic review identified 20 studies in children and adolescents aged between 6 and 19, and found strong and consistent evidence for detrimental effects of portable touchscreen devices on sleep quality and quantity (Carter, Rees, Hale, Bhattacharjee, & Paradkar, 2016). All studies used parent questionnaires, and have reported a significant effect of screen time on sleep: increased amount of TV viewing was associated with parent-reported sleep problems, shorter night-time sleep duration, reduced quality of sleep, and irregular naptime and bedtime schedules, adjusting for known confounds including socioeconomic status (SES).

Using a large scale survey, researchers have started to investigate the relationship between touchscreen use and sleep in infants and toddlers between 6 and 36 months of age. Parents were asked to report on the average duration of their child’s daytime and night-time sleep, the time taken for their child to fall asleep, as well as the frequency of night awakenings, to obtain a comprehensive account of infant/toddler sleep patterns.

The UK-based survey on 715 families, reported that 75% of toddlers between 6 months and 3 years of age use a touchscreen on a daily basis. The researchers found that the prevalence of daily use increases substantially with age, from 51% in 6- to 11-month-old infants to 92.05% by 25–36 months. Among users, daily usage increased with age from 8.53 minutes a day (6–11 months) to 45 minutes a day (26–36 months). The average touchscreen usage in this sample is 24.44 minutes.

There was a significant association between touchscreen use and duration of sleep at night, and sleep onset (the type it takes to falls asleep), with increased touchscreen use associated with decreased night-time sleep, increased daytime sleep and a longer sleep onset. There was no significant association between touchscreen usage and frequency of night awakenings. Results also showed that increased touchscreen use was associated with decreased overall amount of sleep. The researchers concluded that every additional hour of touchscreen use is associated with an overall reduction in sleep of 15.6 minutes.

The blue wavelengths emitted by electronic devices—which are beneficial during daylight hours because they boost attention, reaction times, and mood—seem to be the most disruptive at night. While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully. Researchers conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours). (Harvard, 2015).

It is worth noting that touchscreen use may also have positive effect on some aspects of development. In a recent study of the same sample of infants and toddlers, increased active touchscreen use was associated with earlier achievement in fine motor milestones (Bedford, Saez de Urabain, Cheung, Karmiloff-Smith & Smith, 2016).

Together, these findings emphasize the need for a more in-depth understanding of how to maximize benefits and minimize negative consequences of this modern technology.
