Vitamin D Deficiency Symptoms Explained: The Top 9 Warning Signs
by Aurora Geib
(NaturalNews) The importance of vitamin D is well known. As far back as the 1930s, doctors first recognized the link between a vitamin D deficiency and the skeletal disease called rickets. Rickets causes a softening of the bones and teeth. Even if someone's diet has adequate levels of calcium, without enough vitamin D to properly control calcium and phosphate levels in the blood stream, demineralization of the bones can take place. The symptoms of rickets include bowed legs, bone pain, dental problems, a widening of the wrists, frequent bone fractures and skull deformities.
Because rickets is seldom seen in first-world countries, it's easy to think that vitamin D deficiencies are a thing of the past. However, new research has recently shed light on other, more subtle, symptoms of a vitamin D deficiency. Many illnesses which, at first glance, seem totally unrelated to something as physically obvious as rickets actually may have their roots in a lack of vitamin D.
Just what is vitamin D?
The term vitamin D, according to the Mayo Clinic's Drugs and Supplements site (1), actually refers to several different forms of the vitamin, including D2, which comes from our diet, and D3, which is manufactured by our skin when exposed to sunlight. Vitamin D's main purpose in the body is to regulate blood levels of calcium and phosphorous.
The sunshine vitamin?
It's actually hard to get enough vitamin D from a normal diet. It's found at the highest concentration in fatty fish such as tuna, mackerel and salmon. Some mushrooms are also high in D, and their level of the vitamin actually increases when exposed to ultraviolet light.
While our skin does manufacture some of the vitamin D that we need daily, sun exposure alone is usually not enough. Factors such as the time of year, the angle of the sun, cloud cover, pollution levels and even the use of sunscreen can greatly limit the amount of D made by our skin.
Vitamin D deficiency symptoms explained: the top 9 warning signs
Some people who have a vitamin D deficiency have no immediate symptoms. Those who do have symptoms may experience restless sleep, muscle cramps, general fatigue, joint pain, muscle pain or weakness, inability to concentrate, headaches, constipation or diarrhea, and bladder problems. Here are nine other serious medical conditions that have been linked to a vitamin D deficiency.
1.Asthma - Vitamin D supplementation of 1,200 IU daily has been shown to lessen asthma attacks and reduce their severity.
2.Depression - Vitamin D deficiencies have been linked to depression and other psychiatric illnesses. Even a woman getting enough D during pregnancy has been shown to lessen the chances that her unborn child will develop mental illness later in life.
3.Heart disease - An article published in Molecular Nutrition & Food Research (2) reports that cardiovascular disease is much more common in people deficient in vitamin D. Some children, according to the article, with severe heart failure have also responded well to vitamin D treatment.
4.High blood pressure - High blood pressure has been associated with deficiencies in calcium, magnesium, potassium and vitamin D.
5.Rheumatoid Arthritis - RA is a devastating disease that causes systemic inflammation, severe pain and joint damage. Studies have shown that vitamin D can ease the pain and stiffness associated with RA.
6.Multiple sclerosis - Studies have shown that geography matters when it comes to the odds of getting MS. The farther from the equator you live -- and the less sun exposure you get -- the more likely you are to develop the disease. This suggests a strong link between MS and vitamin D.
7.Cancer - Several different kinds of cancer have been linked to D deficiencies, including breast cancer, prostate cancer and colon cancer. The causal link is so strong, in fact, that the Mayo Clinic (3) lists separate recommended dosing levels of the vitamin for both cancer prevention and prostate cancer treatment.
8.Periodontal disease - This inflammation of the gums can cause pain, bleeding and tooth loss. Vitamin D helps in the formation of defensins and cathelicidins which, in turn, can lower the number of harmful bacteria in the mouth.
9.Diabetes - An article from World's Healthiest Foods (4) lists poor blood-sugar control as a symptom of vitamin D deficiency. This, in turn, can increase the risk of developing diabetes.

Vitamin D And Osteoporosis: How This 'Miracle' Vitamin Can Restore Optimum Bone Health In Men And Women
by Aurora Geib
(NaturalNews) More than 50 million Americans suffer from osteoporosis, literally "porous bones," a condition that occurs when your body doesn't replace bone cells that are lost naturally over time. (1) Lose too much bone, and your bone density drops, making you much more prone to fractures, especially as you age. Vitamin D has been identified as a primary role player in preventing osteoporosis. Here's how it can help you prevent the disease:
Vitamin D and healthy bones
Nearly everyone understands that calcium is important for developing healthy, strong bones: Calcium helps bones remineralize and make new bone cells to prevent weaknesses and fractures. But many people are unaware that, without adequate vitamin D, calcium would be unable to do its job.
Calcium is one of the most prevalent and most important minerals in your body, and about 99 percent of the calcium that your body contains is found in the teeth and bones. (2) We get calcium from the foods we eat, but once we consume those foods, the calcium needs to be absorbed into the blood and tissues in order to do its job.
Vitamin D helps calcium be absorbed into the blood stream so it can travel to the bones and other parts of the body where it can be used. Without vitamin D, your body would not be able to absorb enough calcium to produce new bone cells and keep your bones strong.
In addition to helping prevent bone loss, vitamin D can also help prevent fractures by strengthening muscles and nerves, making bone-breaking falls less likely to occur.
The link between vitamin D and osteoporosis
People who develop osteoporosis tend to have significantly lower levels of vitamin D in their blood compared to people who don't have the disease. (3) Several studies have examined this link to determine whether taking vitamin D supplements can help prevent the disease from occurring. So far, the results of these studies have been encouraging.
For instance, in one study from the United Kingdom, researchers found that women who took vitamin D supplements had stronger, denser bones than women who were not given the supplement, suggesting that supplementation may provide a viable way to prevent the bone loss that typifies the disease. (4) Likewise, a study from the U.S. looked at older patients with and without osteoporosis and found that those who took vitamin D supplements had a significantly lower level of fractures than those who did not take the supplements. (5)
Are you at risk for osteoporosis?
Osteoporosis can affect anyone, but some people have characteristics or habits that place them at greater risk for developing the disease. These are the primary risk factors for developing osteoporosis:
* Female gender (women are about twice as likely as men to have osteoporosis)
* Older age
* Caucasian or Asian race
* Family history
* Small bone structure
* Low sex hormone levels
* Overactive thyroid, parathyroid or adrenal glands
* Sedentary lifestyle
* Smoking
* Excessive use of alcohol
* Poor diet/eating disorders
* Use of some medications, including steroids and some medicines for cancer, depression, immune disorders, gastric reflux and seizures
Especially if you have one or more of these risk factors, taking vitamin D may help prevent or slow the bone loss and loss of bone density that can result in osteoporosis. (6)
Getting enough D
We can get vitamin D from some of the foods we eat, including fatty fish and milk, and we can also get vitamin D from sun exposure. The ultraviolet rays in sunlight cause changes in our skin which help chemicals called previtamin D convert into vitamin D that can be used by our bodies. However, sunscreen, shade and seasonal changes can all have an impact on how much UV exposure our skin receives. In fact, several studies have shown that decreased sun exposure during the winter months results in lower levels of vitamin D and, subsequently, higher numbers of fractures. (7) (8) (9)
Because modern diets and lifestyles can prevent us from getting enough vitamin D through these natural sources, taking a supplement can be an important part of making sure that the body receives enough of the vitamin to help prevent bone loss and to experience other benefits of the vitamin.
Vitamin D helps build strong bones, and it can also help the body in other ways, including strengthening the immune system, preventing diabetes, treating high blood pressure -- even decreasing the risk of certain types of cancer. If you're concerned that you may not be getting enough vitamin D in your regular routine, taking a vitamin supplement could be an ideal solution for ensuring that you're experiencing all the benefits of this miracle vitamin.

Low Vitamin D Levels Increase Risk Of Early Death For 66 Percent Of Americans
by Julie Wilson
(NaturalNews) The sun is quintessential in facilitating life on planet Earth, meeting the biological requirements of species in all forms. In addition to making our existence possible, sunlight makes us feel good, and according to a new study, keeps us alive longer.
While some places on Earth experience endless amounts sunshine, others aren't so lucky. Large populations residing in colder regions consider sunlight a delicacy, many flocking to the Sunbelt of the southern and southwest United States. The equator divides the Earth's surface between the North Pole and the South Pole. The further you are away from the equator, the greater of an angle the sun hits the atmosphere, making it more difficult to absorb the sun's most natural rays, or ultraviolet B (UVB).
Those of us fortunate enough to live in the Sunbelt, have less to worry about when it comes to getting enough vitamin D. The amount of sunlight needed to maintain vitamin D levels depends on a few different factors including the time of day, where you live, the color of your skin and the amount of skin you expose.
Your body produces more vitamin D when exposed to natural light during mid-day when the sun is it hottest. Pale skin absorbs sunlight faster therefore requiring less time spent outside. Those of us with pale skin require about 15 minutes of direct sunlight daily, and those with darker skin tones could need up to two hours in order to acquire enough of the sunshine vitamin.
Factors like air pollution, altitude levels, the weather, and sunscreen can also affect how much sunlight you absorb.
Sunlight essential for optimal health
Regardless of the limitations, getting enough vitamin D is extremely important to living a healthy and happy life. The sunshine vitamin helps facilitate muscle function, strengthens your bones, decreases your chance of heart disease and even reduces the likelihood of getting the flu.
Researchers from the University of California, San Diego School of Medicine discovered people with the lowest levels of vitamin D in their blood were 90 percent more likely to die prematurely than those with the highest concentrations of the vitamin. People with vitamin D levels of 30 ng/ml or less experienced a higher risk of dying early.
The study's lead researcher, Dr. Cedric Garland reported that approximately 66 percent of the U.S. population suffers from vitamin D deficiency.
"Three years ago, the Institute of Medicine (IOM) concluded that having a too-low blood level of vitamin D was hazardous," said Dr. Garland, professor in the Department of Family and Preventive Medicine at UC San Diego.
"This study supports that conclusion, but goes one step further. The 20 nanograms per milliliter (ng/ml) blood level cutoff assumed from the IOM report was based solely on the association of low vitamin D with risk of bone disease. This new finding is based on the association of low vitamin D with risk of premature death from all causes, not just bone diseases."
The study published in the June 12 issue of American Journal of Public Health, analyzed the blood of more than a half a million participants with an average age of 55, throughout 14 different countries. The publication examined the relationship between vitamin D blood levels and various types of death from 32 studies conducted over nearly an 80 year period.
While foods like salmon, sardines, egg yolks, shrimp, and milk provide us with vitamin D, it's difficult to obtain the amount required through foods, but taking vitamin D supplements can do the trick if you're reluctant or unable get sun exposure.
It's also important to remember that people 50 years or older require more vitamin D than younger folk, and getting too much sun that results in burning is dangerous. "Research to date shows that moderate but frequent sun exposure is healthy but overexposure and intense exposure can increase your risk of skin cancer," according to a report by the Vitamin D Council.

Vitamin D Deficiency Could Be Linked To Early Death, Study Finds
by Sandeep Godiyal
(NaturalNews) A lack of vitamin D might be linked to early death. Vitamin D is common in milk, cheese and other dairy products. It is known by most to come from the sun, and getting sunlight is a part of many exercise regimens. The lack of this vitamin may be more detrimental than first noted by scientists. Without it, staying healthy and surviving disease may be more difficult.
In today's marketplace, foods are fortified with vitamin D. Scientists have known that the body needs this vitamin to live but have now confirmed that lacking this nutrient may cause death. Vitamin D is one of the key components to keeping healthy. The sun is a primary source of this vitamin. There are two main forms that are important for humans, D3 (cholecalciferol) formed by sun exposure and D2 (ergocalciferol) manufactured by fungi. These compounds need transformation by the liver and kidneys before they are useful to the body.
Benefits
Vitamin D is important to protect the body from colds, heart disease, cancer and a host of other ailments. It is believed that, when the body's vitamin D level is low, it is easier for disease to attack the body. The flu can become a serious problem for people with weakened immune systems. Thousands die from cancer each year, but people with low vitamin D levels are more susceptible to such life-threatening illnesses. Some feel that vitamin D levels affects a person's ability to lose weight, but studies have shown no significant evidence. This nutrient is especially helpful when combating colon cancer.
How the body uses vitamin D
The body uses vitamin D to transmit nerve messages throughout the body. It aids in keeping the bones strong and fights off viruses. The strongest foods for vitamin D are mackerel, salmon and other fish with high fat content. Getting enough of this nutrient may slow the progress of many diseases. Although vitamin D is manufactured when skin is exposed to sunlight, having darker skin or sitting indoors reduces the absorption level.
Studies
Research studies of over 500,000 people from around the world have shown that people lacking vitamin D in their blood are subject to more life-threatening illness than groups with higher concentrations of this vitamin in the body. It has been discovered that the body requires 1,000 to 2,000 IU of this nutrient, yet the daily dose listed by the National Institutes of Health is 600 IU. This is a diverse range for what is considered optimal.
Since many foods have this vitamin included in their makeup, getting the amount needed is possible if a proper diet is a part of the daily routine. Each person has a different level of vitamin D. This makes it important to seek medical advice before seeking to increase vitamin D intake. More people are taking supplements, working tirelessly to fight off illness, but an overuse of supplements can create other problems.

Vitamin D Supplementation - How Will It Help Me Improve My Health?
by Aurora Geib
(NaturalNews) Imagine a line stretching across the U.S. from Philadelphia in the East to just north of San Francisco in the West. That's about 40 degrees latitude. If you live north of that line, chances are, you're not getting enough vitamin D. And even if you live in the more southerly latitudes, if you're not getting outside to enjoy the sunshine for at least 15 minutes each day, it's pretty likely you're not getting enough D either. Likewise if you're dark-skinned, overweight or older.
That's because most of us get our D vitamins through sun exposure. When exposed to the UV rays of the sun, compounds in the skin work to convert chemicals into vitamin D. People in more northern latitudes are seasonally limited to the amount of sun they receive, and for those who have dark skin or who are older, the skin isn't as efficient at converting sunlight to vitamin D.
Vitamin D is different from other vitamins because it's available in only a few foods -- mostly fatty fish and mushrooms that have been exposed to UV rays. As a result, vitamin D supplementation is typically the best way for most people today to ensure that they get enough of the vitamin.
Until just a few decades ago, vitamin D's effects were largely believed to be solely related to healthy bones. Researchers understood that vitamin D helps the body absorb calcium, which is essential for healthy bone development. But more recently, evidence has surfaced that's shown there's much more to this vitamin than originally believed.
Strengthening Bones and Muscles
Multiple studies have shown that the risk of fractures, especially among older people, is significantly higher when vitamin D levels are low. In a summary of evidence found in 12 studies, researchers determined that taking vitamin D supplements reduced hip and other non-spinal fractures by 20 percent. (1)
And another study found that, among an older population, vitamin D's muscle-strengthening powers helped decrease the risk of falls -- a common cause of disability and death -- by nearly 20 percent. (2)
Preventing Heart Disease
Just like bone and muscle cells, heart cells also have special receptors that attract and bind vitamin D. No surprise, since the heart itself is a type of muscle. Multiple studies have found that vitamin D deficiency contributes to heart disease, although the reasons why aren't clearly understood. Many researchers believe that it's because vitamin D can help prevent three of the most common diseases that contribute to heart disease -- high blood pressure, atherosclerosis (hardening of the arteries) and diabetes.
Preventing Cancer
To date, studies have shown a strong link between low levels of vitamin D and the development of colorectal cancers, but more studies are being conducted to learn how the vitamin may play a role in the development and prevention of other cancers, including breast and prostate cancers.
Preventing Kidney Disease
Studies conducted during the past decade have shown that low levels of vitamin D play a role in the development of kidney disease, but as recently as last year, researchers learned that monitoring the levels of the vitamin can actually help identify the disease in its earliest stages before significant kidney damage occurs. According to the results of that study, people with deficient levels of vitamin D were two times as likely to have protein in their urine -- a condition known as proteinuria, one of the earliest signs of kidney damage. (3)
Strengthening the Immune Function
Low levels of vitamin D have been shown to contribute to tuberculosis, multiple sclerosis, flu and even the common cold. It's also been associated with type I diabetes, the type of diabetes that's related to the immune system and begins almost exclusively in childhood. Low levels of vitamin D have also been associated with type II diabetes, which usually occurs in adults over the age of 40 and is not associated with the immune system. Most researchers believe that the vitamin's ability to ward off inflammation is at the root of its immune-boosting abilities. (4)
Studies indicate that about 1 billion people worldwide are deficient in vitamin D. (5) Especially in recent years, vitamin D's role in preventing a host of diseases is becoming more clearly understood. Multiple studies are underway to explain these roles, but one thing is clear: Getting enough vitamin D is vitally important to maintaining good health. Since getting enough of the vitamin can be so difficult, taking a supplement is the best way to enjoy its benefits.

What They Won't Tell You: The Sun Is A Full-spectrum Medicine That Can Heal Cancer
by Paul Fassa
(NaturalNews) "Those that have attempted to convince the world that the Sun, the Earth's primary source of energy and life causes cancer, have done so with malicious intent to deceive the masses into retreating from the one thing that can prevent disease." -- Dave Mihalovic, Naturopathic Doctor
and writer. [1]
Truth is, we've been systematically lied to about the sun and skin cancer for years. This video presentation explains fully. How many know that there is no definitive proof that the sun alone causes skin cancer? [2]
Can the sun cure cancer?
In the book The Healing Sun, author Dr. Richard Hobday documents a wide array of studies which show that the sun protects against cancer of the breast, colon, ovaries and prostate. It can also prevent diabetes, multiple sclerosis, heart disease and high blood pressure, osteoporosis, psoriasis and seasonal affective disorder (SAD). [3]
Then there's the case of Dr. Harland G. Call, who was diagnosed with skin cancer and was advised by a surgeon to have it removed. Instead, he decided to sunbath the cancerous area.
After a short period of continuous sunbathing, the skin cancer was completely gone. He returned to his MD for a confirmation, and his doctor confirmed that the skin cancer had disappeared and no surgery was required. [3]
According to Dr. Bernarr Zovluck, "Cancer is helped by sunbathing, writes Dr. Zane R. Kime. Kime writes
that those who get more sunlight have less cancer. Sunbathing heals
cancer by building up the immune system and increasing the oxygen in the
tissues." [4]
Still, we're bombarded almost daily with dire "warnings" from reputable "authorities" admonishing us, for our own good of course, to avoid the sun at all costs.
Epidemic levels of sun phobia
For example, Dr. Robin Ashinoff, chief of dermatological and cosmetic surgery at Hackensack University Medical Center advised: "Wearing sunscreen and then deliberately going out in the sun is almost as [bad] as going out with no sunscreen at all."
She continued, "You don't get burned, but the UV rays are still getting into your skin. Sunscreen is important, but you should also wear the right clothing and shield yourself as much as possible from direct sun exposure." [5]
Is Dr. Ashinoff advocating a vampire lifestyle? The reality is that the vast majority of people, including doctors, have been duped into believing the myth that the sun is toxic, carcinogenic and a deadly health hazard.
That's why most people slavishly and lavishly slather toxic sunscreens on their skin whenever they anticipate direct contact with the sun's rays. But in fact, most conventional sunscreens are cancer-causing biohazards. [6] [7]
Meanwhile, the multi-billion-dollar cancer industry and the billion-dollar toxic sunscreen industry are making hay with this hoax. True believers are left scratching their heads in bewilderment as statistics reveal that the dreaded malignant melanoma skin cancer is on the rise. [8]
The sun doctor
Dr. Auguste Rollier opened the first European "Sun Clinic" in 1903 at Leysin, Switzerland. He also wrote a very influential book: Heliotherapy. He was considered the most famous heliotherapist in the world.
At his peak, he operated 36 clinics. Dr. Rollier espoused that the sun was an unsurpassed broad-spectrum medicine. He healed his patients using a wholesome diet combined with the power of the sun.
By 1933, there were over 165 different diseases successfully treated with heliotherapy including tuberculosis, wounds, rickets and much more. Dr. Rollier's death in 1954 marked the end of sun therapy not because it was ineffective, but because it had been replaced by Big Pharma's "miracle drugs." [9]

Vitamin D Hailed In The Fight Against Heart Disease, Alzheimer's Disease And Diabetes
by John Phillip
(NaturalNews) Scientific research bodies extolling the amazing virtues of the prohormone vitamin D have been published in rapid succession to explain the preventive mechanism shown to prevent cardiovascular disease, diabetes and Alzheimer's disease. Three independent reviews demonstrate that maintaining a vitamin D blood level between 50 and 70 ng/mL can provide optimal protection against many chronic diseases.
Researchers' publishing in the journal Nutrition, Metabolism & Cardiovascular Diseases provide evidence that vitamin D is intrinsically involved in the homeostasis of the cardiovascular system. Disruption of the body's natural stasis system contributes to diabetes, obesity, elevated blood lipids, high blood pressure, endothelial dysfunction, stroke and risk of coronary artery disease. Scientists advise supplementation of 4,000 to 8,000 IU of vitamin D per day to achieve optimal levels, far above the anemic 400 IU currently recommended.
Scientists at the University of Miami's School of Medicine demonstrate a direct genetic link between low vitamin D levels and the development of amyloid proteins in the brain, commonly associated with Alzheimer's disease. Reporting in the journal Neurobiology of Aging, researchers looked at gene signaling in relation to the vitamin D receptor in 492 late onset Alzheimer's patients and 496 control subjects.
Vitamin D controls genetic receptors to guard against chronic disease
When vitamin D receptors were not activated on the surface of individual cells due to poor vitamin D saturation in the blood, precise gene signaling went awry that halted normal clearance of the dementia-related protein clumps. The team conducting the study concluded "Our findings are consistent with epidemiology studies suggesting that vitamin D insufficiency increases the risk of developing Alzheimer's disease."
Researchers in Spain evaluated the vitamin D status of 1,226 individuals in 1996. The participants were again tested eight years later, and vitamin D levels were contrasted with development of diabetes over the course of the study. The results, published in the journal Clinical Nutrition, found that those with vitamin D blood levels above 18.5 ng/mL had an 83 percent lower risk of developing type 2 diabetes during the eight-year period. No one in the study with a vitamin D score over 30 ng/mL developed type 2 diabetes.
It has become very clear from countless research studies published over the past decade that vitamin D qualifies among the most crucial and essential hormone-based nutrients. And still millions of people continue to place themselves at unnecessary risk by ignoring this information.
Most people above the age of twenty-one should supplement with a minimum of 2,000 IU of vitamin D every day and have their blood tested to ensure they reach the optimal range of 50 to 70 ng/mL. Extensive research provides more than sufficient evidence that maintaining a proper vitamin D level can dramatically lower the risk of heart disease, Alzheimer's disease diabetes and many other chronic illnesses.

Artificial light exposure, lack of sunlight tied to cancer, diabetes and depression, evidence shows
by Mayimina Mutijiang
(NaturalNews) Natural light from the sun is very important to the general health and well-being of humans. Recent research has reinforced this; humans need to have regular and prolonged exposure to this natural light so they can experience optimal health.
According to one research team, however, not all the news is good.
For many people, a sort of double-whammy ensues in that they not only don't get sufficient sunlight during the day, but that during the evening, they surround themselves with unnatural lights that researchers say is physiologically unsettling.
A simple solution can make the difference between a person's mood as well as their overall health. Implementing these methods on a regular basis can even help ward off chronic diseases.
Let's take a closer look at what researchers found about artificial light exposure.
From sleep disruptions to developing cancers, researchers warn of artificial light
For 30 years, Richard Stevens, a cancer epidemiologist at UConn Health, has been studying how the human body reacts to artificial lighting.
His latest research hones in on the tendency of humans to spend a great deal of time indoors and away from the sun, followed by hours in the dark surrounded by artificial lighting. For example, many people rest in bed in the evening browsing through their laptop or cell phone, basked in the glow of light that's emitted from these devices.
His team discovered that those who used e-readers had more reduced levels of the sleep-promoting hormone, melatonin, in their system compared to study participants who read a physical paper book.
"It's become clear that typical lighting is affecting our physiology," says Stevens. "We're learning that better lighting can reduce these physiological effects. By that we mean dimmer and longer wavelengths in the evening, and avoiding the bright blue of e-readers, tablets, and smart phones."
Simply put, the body was designed to be immersed in natural light for many hours a day, not artificial light for long periods of time at night.
Surrounding ourselves with such lighting can lead to serious health problems beyond sleep disruptions.
Steven's adds that "there's growing evidence that the long-term implications of this have ties to breast cancer, obesity, diabetes, and depression, and possibly other cancers."
"Too much light at night" problematic for health
Along with a co-author of his study, which was published in the British journal Philosophical Transactions of the Royal Society B, Stevens expressed that though time, artificial lighting has become increasingly problematic.
An abstract from the journal states:
Over many, many years, an endogenous circadian rhythmicity has developed in almost all life forms in which daily oscillations in physiology occur. This allows for anticipation of sunrise and sunset.
It's explained that such rhythms are based on a 24-hour cycle. But the article published in the journal says that changes in people's habits have altered this. It says:
However, since the introduction of electric lighting, there has been inadequate light during the day inside buildings for a robust resetting of the human endogenous circadian rhythmicity, and too much light at night for a true dark to be detected; this results in circadian disruption and alters sleep/wake cycle, core body temperature, hormone regulation and release, and patterns of gene expression throughout the
body.
The harm of blue light, simple solutions to this modern issue
Today's modern devices -- from smart phones and tablets to e-readers -- emit a blue light that is harmful to people. As mentioned, this artificial blue light changes the body's own natural circadian rhythm while also suppressing melatonin, the human body's sleep-inducing hormone.
Such lighting of what should otherwise remain a naturally dark environment impacts every living thing from humans and animals to plants and insects.
Steven's notes that this study reinforces what many others have touched on in that artificial light can be detrimental to overall health. However, he says that people do not need to deprive themselves of light at night time.
Instead, he suggests people switch from e-readers to old fashioned books when reading in the evening in order to minimize disruption to the body. "It doesn't mean you have to turn all the lights off at eight o'clock every night," he says, "it just means if you have a choice between an e-reader and a book, the book is less disruptive to your body clock."
Lights that help maintain a human's circadian rhythm at night tend to be dim and red like that emitted by incandescent bulbs, so giving those lights consideration is also recommended.

Sunlight is GOOD For Your Eyes! Lower Risk of Nearsightedness Associated With More Time Outdoors
by Melanie Grimes
(NaturalNews) Sunshine can reduce eye problems, new research shows. In addition to the many benefits of being outdoors, a study has now shown that nearsightedness, also known as myopia, was less common among children who spend more time outdoors each day.
The study, which was published in the Journal of the American Medical Association (JAMA), observed two groups of first-graders in China. One group was encouraged to spend an additional 40 minutes playing outdoors, while the other wasn't. After three years, the students who were outside more often had a 23 percent less onset of myopia than the other.
As many as half the children in the United States are thought to suffer from myopia. The condition is even more widespread in China and most of East Asia. At present, there are no known treatments to completely prevent it.
What is myopia?
Myopia is a medical condition commonly referred to as nearsightedness. People with myopia cannot clearly perceive objects in the distance, though they can see objects that are close to them. Myopia occurs if the eyeball is elongated or if there is a curvature to the cornea, the clear cover of the eye. If the light coming into the eye is not focused properly, distant objects tend to look blurry.
It is estimated that 30 percent of Americans have myopia. The condition is made even worse by eye strain caused by reading, looking at computer screens or using cellphones. Myopia is usually first observed during a child's early years of schooling. The eye continues to grow until the age of 20, so the condition can set in at any time before then. Myopia can also develop later in life from severe eye strain or from health conditions, such as diabetes.
One of the first indicators of nearsightedness is an inability to see a school chalkboard or television screen. The condition can be corrected by glasses, contact lenses or laser surgery. Another non-surgical option is corneal refractive therapy, which involves wearing special contact lenses that cause the cornea curvature to reshape and become flatter, thereby causing less blurriness from the light entering the eye.
Sunlight exposure prevents nearsightedness
The research on sunlight and vision was conducted by Dr. Mingguang He of the Sun Yat-sen University of Guangzhou. For three years, 1,900 first-graders from twelve different schools in the same area were observed. Six of the schools maintained the normal school schedule, while the other six allowed the children to play outside for 40 minutes more each day. Parents of those in the latter group were also encouraged to allow their children to play outside more frequently.
By the end of the three-year research period, 39.5 percent of children from schools that had no extra outdoor playtime developed myopia. On the other hand, the children who were outside more often registered a 30.4 percent incidence of nearsightedness, showing a 9.1 percent difference between the two groups.
While more research is needed to confirm these findings, this study adds to the already extensive list of benefits we could get from outdoor activities — Vitamin D for the skin, mood improvement, disease prevention and even cancer reduction.
The bottom line is: playing outside, being outside, enjoying nature and being exposed to the right amount of sunshine is not only good for the eyes, but for the body and the soul as well.
