More sun, less covid

Coronavirus, sun, vitamin D. An opportunity to save lives

Coronavirus, sunlight and vitamin D. More compelling information. Take action now. By Marc Sorenson, EdD.

Preventing coronavirus with sunlight

Coronavirus writer, Marc SorensonCoronavirus, (Covid-19), like most flu-like diseases, will probably disappear in much of the Northern hemisphere in the coming summer.  Nevertheless, it will return on steroids in the fall and winter. Yet, it does not have to return to you or your family and friends. We can do something!  However, why wait?  Let us start now! Does anyone reading this really want to wait for the “second wave” and then go into panic mode? Of course not. In addition, do you want to let the vaccine Nazis also spend $billions more of our tax dollars looking for a vaccine? Of course not. The answer to stopping coronavirus is all around us. We need only to seek it and use it.

Two papers show remarkable associations of coronavirus with vitamin D.

If you are not convinced of the power of sunlight after reading this, I despair of being able to help you prevent this fall’s “second wave.”

The first paper was by a team of Indonesian researchers. One might think that Indonesians would have ample vitamin D levels due to an abundance of sunlight. Thus, this should protect them from vitamin D deficiency. However, most Indonesians avoid the sun and keep their skins as white as possible. It is a national quest in the Philippines to be as light-skinned as possible, so that they can consider themselves as “upper crust.” Hence, the population has a great deal of vitamin D deficiency.

The researchers focused on identifying patterns of mortality (death) between coronavirus deaths and vitamin D levels. They conducted the study with a sample of 780 subjects, all who had laboratory confirmed coronavirus infection.

Here are the findings on vitamin D levels and coronavirus mortality:

  • Mortality rates were 13 times higher in patients who were vitamin D insufficient (21-29 ng/ml) compared to those who had normal levels (>30 ng/ml).
  • Mortality rates were 19-times higher in patients who were vitamin D deficient (<20 ng/ml).
  • Even when controlling the data for age, gender and preexisting conditions, the vitamin D deficient cases were more than 10 times more likely to die than those who had normal levels.

No wonder the Indonesians are now seeking the sun and appreciating it after years of avoiding it. See the picture below of Indonesian men social distancing while soaking up the rays.

Indonesians fighting coronavirus in the sunlighto

An important point regarding vitamin D and coronavirus:

Vitamin D levels above 30 ng/ml are not necessarily “normal,” and it is likely that 50-60 ng/ml would be a better number.  People who are constantly in the sunshine, i.e. lifeguards, often have levels above 70 ng/ml. Dr. Bruce Hollis and his colleagues suggested that lifeguards have the “true normal” levels. They believe that a population of “normal” volunteers with average levels of 27 ng/ml may exhibit vitamin D deficiency. Another similar study showed that “normal” adults had 25(OH)D levels of about 27.2 ng/ml, whereas lifeguards had levels of approximately 70 ng/ml].

Could the real pandemic be a pandemic of sunlight deficiency resulting in a pandemic of vitamin D deficiency?

If  >30 ng/ml provides this much protection against coronavirus, levels > 60 ng/ml would probably provide complete protection.  Everyone should have a vitamin D assessment, and then get out in the sun, during this time of the coronavirus epidemic. For your own health, and the health of those you love, schedule a test, and make your goal 60 ng/ml.

Paper # 2

 Another paper by Mark Alipio, done in the Philippines, was similar to the Indonesian study. Thus, it showed that coronavirus patients with normal vitamin D levels had a mild disease outcome. The outcome for those patients was 19.6 times better than for those with low levels.

 A fact everyone should remember:

 Ninety percent of serum vitamin D levels are due to sun exposure, which causes the skin to produce vitamin D3. Therefore, vitamin D levels are surrogate measurements for sun exposure. You must not assume that vitamin D capsules will supply all the beneficial effects of sun exposure or sunbed exposure. Both sunlight and sunbed light produce photoproducts that have health effects far beyond vitamin D. Safely sunbathe (without burning) to achieve optimal vitamin D levels. Moreover, while so doing, you will produce other remarkably important health benefits.

Covid-19 (Coronavirus) in Florida & New York. Sunlight?

Covid-19 and sunlight, in our hearts and minds, by Marc Sorenson, EdD

Sunlight for Covid-19 exposure

Covid-19 (coronavirus) is a topic that is inescapable in our times.  The media discusses it relentlessly and it is in the hearts and minds of nearly every citizen. And why not? We all know of friends or acquaintances who have had the disease, and it has become a political football. So what can we do about it? There are certain geographical and population differences in Covid 19 incidence and death that may provide some insight. Thus, New York and Florida provide interesting contrasts for the difference in incidence.

Shawn Hannity’s interview with Florida’s Governor DeSantis provides thought-provoking insight and fascinating facts regarding Covid-19.  

First of all, Florida and New York are heavily populated states. Yet, as you can see from this graph, death risk is minuscule in Florida compared to New York. The graph shows the comparison of death rates.

Covid-19 fatalities in New York and Florida

Because of New York’s high population density, with people living nearly on top of each other, epidemic diseases spread easily. Thomas Jefferson, third president of United States, once made this clairvoyant statement. “When we get piled upon one another in large cities, as in Europe, we shall become as corrupt as Europe.” Perhaps he should have used the word “ill” rather than corrupt.  

Here are more reasons for the stark contrast in Covid-19 deaths between New York and Florida.

Here are New York’s responses to the Covid-19 epidemic.

  • New York shut down nearly all social gathering places. Yet, their leaders in the beginning told people to congregate and have a good time.
  • New York made homes a breeding ground for Covid-19 infection with “shelter in place” orders.
  • New York forced many elderly patients and others, whom they had no room for in regular hospitals, to live in nursing homes. Thus, they produced a hotbed for infection. Twenty-five percent of all deaths from Covid-19 in New York occurred in nursing homes.
  • New York has resisted the demand to return people to work and to use outdoor areas with social distancing.
  • Furthermore, New York City was appallingly unprepared to provide masks, ventilators and other medical equipment.

The power of sunlight for health beyond Covid-19

More benefits of sunlight exposure

Conclusions regarding New York, Florida and Covid-19

 Florida made better choices and earlier choices regarding the Covid-19 epidemic. They also opened their beaches in a reasonable manner. This allowed more sun exposure.

When the disease diminishes this summer, it will be due to sun exposure that produces vitamin D and many other healthful photoproducts. In addition, remember, that sun exposure effects positive changes well beyond stopping the coronavirus.

Non-burning sun exposure is essential, and best around midday. Do not overexpose. My previous blog presented guidelines for sun exposure. Also, be sure to read my book, Embrace the Sun. In addition, visit my previous blog for more information.

UV index. —a great gift for health.

UV index.  Vitasunlight and breast cancermin D and health. By Marc Sorenson, EdD

The UV index is a measure of the intensity of ultraviolet radiation B (UVB) from the sun. It is expressed as a number on a scale of 0-11. A higher number indicates a higher sunlight intensity. Exposure to the ultraviolet B (UVB) portion of sunlight is necessary to cause the skin to produce vitamin D. Nevertheless, unless the body is deeply tanned or naturally very dark, a very high UV index can cause sunburn, so caution is necessary.

A low UV index is also problematic.

However, if the UV index is very low, it cannot stimulate the production of vitamin D in the skin. Vitamin D production is essential for human health. Thus, lack of vitamin D may be a major reason that flu-like diseases occur primarily during winter, when there is little or no vitamin D production. This, of course varies according to latitude.

A List of vitamin D benefits from Business Insider.

A recent article from Business Insider (a Philippines online paper) discussed various health effects of vitamin D and sun exposure. Here are some of their salient points, not all of which are correct.

  • The primary cause of vitamin D deficiency is sun deprivation (correct).
  • Vitamin D helps keep the immune system, so deficiency could be the reason for frequent flu (correct).
  • You can get more vitamin D by spending at least 5 to 10 minutes outside 3 times a week without sunscreen (correct).

How much vitamin D does a person need?

  • The most incorrect statement of the article is this. The average adult needs around 600 international units (IU) of vitamin D a day (not correct). For reference, a serving of salmon contains roughly 400 IU (not correct). 20 minutes of full-body, unobstructed sunlight can cause the skin to produce up to 20,000 IU of vitamin D. If 600 IU were the only source of vitamin D, one would produce a level of six ng/ml, which would be woefully inadequate. 600 IU is only slightly better than nothing.
  • Fifteen minutes of non-burning midday sun (without sunscreen) would optimize vitamin D levels in a few days. Dark-skinned individuals would need much more exposure, up to an hour.
  • Getting more frequent colds or respiratory infections could be a symptom of vitamin D deficiency (correct). However, it is even more likely to be a sign of sunlight deprivation.

  • Colds and flu nearly disappear in the summer when the sun is direct. During this time of the coronavirus epidemic, everyone on earth needs daily direct or indirect sun exposure. Those who do not tan can obtain plenty of sunlight from being outdoors under an umbrella or even in the shade near where the sun is shining.
  • Bone diseases, vitamin D and sunlight.

  • Vitamin D deficiency can cause Osteomalacia and Osteoporosis, conditions where your bones become less dense (correct). Sun exposure produces about 90% of the body’s serum levels of vitamin D. In addition, not all vitamin D supplement studies have produced stronger bones.

Sunlight is king for increasing bone strength.

  • However, sun exposure, or exposure to sunbeds (tanning beds) produces marvelous results. For example, a Spanish study showed that women in Spain—those who regularly enjoyed sun exposure—had about one-eleventh the risk of hip fractures as women who had little exposure. Women who use sunbeds also have profoundly higher bone mass than women who do not use them. Their vitamin D levels are also remarkably higher.
  • Mental problems due to a low UV index and subsequent vitamin D deficiency.

  • Vitamin D has some links to depression (correct). Nevertheless, that link in my opinion is 100% due to  to sun deprivation. Dr. Gavin Lambert and his colleagues in Australia measured serotonin levels in response to varying degrees of bright light. To do so, they drew blood samples from the internal jugular veins of 101 men and compared the serotonin concentrations of the blood to weather conditions and seasons. The results were remarkable: Men measured on a very bright day produced eight times more serotonin than those measured on a cloudy, dismal day.

More on the UV index and “solar noon.”

When meteorologists report UV index, the emphasis usually warns against the maximum UV level. That level generally occurs around “solar noon.” Solar noon is a four-hour period stretching from 10:00 AM to 2:00 PM. As you have probably noticed, forecasters constantly warn us to avoid the 10:00 to 2:00 hours. Avoiding intense UV radiation is their watchword. Many of them say, “Get sun exposure in the early morning or late afternoon to produce vitamin D.” They should know that the UV index must be over 3 to produce vitamin D.

These reporters do not understand how low UV index hinders vitamin D production.

They do not comprehend that UV index is so weak in the morning that it produces absolutely no vitamin D. The same is true in the evening. Therefore, the closer to solar noon you plan your outdoor time, the more vitamin D you will produce. Vitamin D produced in the skin from solar UVB exposure does not lead to vitamin D toxicity and is safe, as the body limits its own production.

Another method to measure the efficacy of sunlight for vitamin D is to stand in the sun at any time of day and observe your shadow. If your shadow is shorter than your height, you are producing vitamin D. This, the shorter the shadow, better.

Caveats regarding the UV index and vitamin D. Morning sun is still very healthful. 

Early morning sun exposure, when the UV index is very low, (under 3) has remarkable health effects. These include resetting the circadian rhythm, increasing production of serotonin, lowering blood pressure through nitric-oxide production and assisting weight loss. Nevertheless, vitamin D stimulation in the skin is not one of the health effects of early morning light.

So safely soak up the sun at any time of day and reap the health benefits. Never burn.

Happy sunning!

Death by Prescription Drugs. Is Sunlight better?

Death by Prescription Drugs. By Marc Sorenson, EdD.

Sunlight prevents deathAre there better ways to heal? Could there be better ways to fight the coronavirus? (be sure to scroll down to the WHO flu graph.)

Death by prescription drugs is commonplace. Therefore, perhaps whole foods, avoidance of junk foods and plenty of sunlight are better alternatives. Thus, our approach here will be (1) to explain the health burden inflicted by prescription drugs. (2) To make nutrition suggestions and (3) finally propose exercise and sunlight as additional solutions.

Death and prescription drugs. The danger is real!

Since you probably realize that prescription drugs are ubiquitous, did you also realize just how dangerous they are? Would it get your attention to tell you that they are the fourth leading cause of death?

U.S. News published an interesting article, which makes us wonder if our pharmaceuticals do more harm that good. Are they healers of killers? Here are some of the most noteworthy facts the article presents:

Salient points from the article on Death and prescriptions.

  • First, prescription medications are the fourth leading cause of death and a major cause of additional illnesses among Americans.
  • A recent analysis estimates 128,000 Americans die each year due to taking medications as prescribed.
  • In addition, adverse drug reactions from properly prescribed and used medicines result in 1.5 to 2.7 million hospitalizations each year.
  • Sixty to 70 percent of us take at least one prescribed drug and many take an additional fistful of pills daily.
  • A quote from Dr. Donald Light [apropos, no?], who analyzed the data: “By far the greatest number of [prescription drug-related] hospitalizations and deaths occur from drugs that are prescribed properly by physicians and taken as directed.” This comes from his paper entitled “Institutional Corruption of Pharmaceuticals and the Myth of Safe and Effective Drugs.”
  • Another quote from Dr. Light’s paper: “About 2,460 people per week are estimated to die from drugs that were properly prescribed. And that’s based on detailed chart reviews of hospitalized patients.” [That of course, does not include the 1.5-2.7 hospitalizations that occur due to prescriptions.]
  • The paper continues, “And though following a doctor’s orders and medication labeling instructions can reduce harms associated with taking prescription drugs, simply taking prescribed drugs as directed can expose a person to significant risk.”

Of course, properly prescribed drugs can save lives. Yet, do these drugs give us the best odds? They do not.

All of this begs a question. Does the brouhaha caused by coronavirus not pale in comparison to the millions of lives lost to drugs? Of course, I believe in finding a cure. Nevertheless, when this pandemic subsides, should we not first look at ways to stop death due to prescription? There are better ways to prevent and cure illnesses, and the people must be educated. Knowledge not disseminated is no better than no knowledge at all.

An illustration of a better way than prescription drugs to stop death by diseases—diabetes and other maladies

An example: 2/3 of diabetics who attended our resort were able to stop medications in 11.7 days because of nutrition. In addition, of course, they soaked up the sun. Also, 85% of those who stayed for four weeks were able to leave without the meds. The avoided meds included injected insulin and hypoglycemic drugs (Metformin, Glucotrol, etc.]. That seems like a better option than another drug to “prevent” death. Of course, people must be willing to make changes to heal themselves. Avoiding death is unlikely if a person would rather die than part with junk food. The people at our resort liberated themselves from drugs by making the right choices.

And what about death from other diseases?

Diabetes, of course, was only one of myriad diseases they left behind when they returned home from their sojourns with us. A few others were arthritis, headaches, muscle pain, heart disease, lupus, asthma and obesity. Even erectile dysfunction, mood disorders, endurance and eyesight improved. In addition, nothing we did involved drugs and supplements. Good food, exercise and sunlight were the “medicines” we used. As Hippocrates once stated, “Let Food be your medicine.” He should have added, “Let sunlight and exercise also be your medicine.”

You knew I would get to sunlight and death, did you not?

Another method to enhance human health, while reducing human death: Bring people back into the safe, non-burning sunlight. My latest book, Embrace the Sun, co-authored by Dr. William Grant, has some interesting analyses. There are, in the U.S., according to our calculations, approximately 1,684,677 yearly deaths caused by diseases associated with sun deprivation. That compares to 5125 deaths from diseases associated with high sun exposure, producing a ratio of approximately 328:1. Now you can live with those odds (no pun intended)! Do we really need all those drugs if we give up our killer nutrition and soak up some non-burning sunlight?

Here are some facts everyone should know about death-preventing effects of regular, non-burning sun exposure:

Therefore, you see, good nutrition and sunlight can reduce the need for prescriptions and lighten one more death  burden.  Embrace the Sun.

The phone: Is it destroying your sleep? Try sunlight!

The phone, sunlight and sound sleep. By Marc Sorenson, EdD. Don't sleep with the phone!

The phone is ubiquitous, and it may be taking away a basic human need: sound and restful sleep.

How should the sleep/wake cycle work?

First of all, we awake to bright sunshine. Light enters the eye and stimulates serotonin production. Serotonin is a natural “upper” and mood elevator. Thus, we quickly become awake and invigorated. The bright sunshine also suppresses melatonin, the sleep inducer. Yet at evening light disappears (at least that is how nature intended it), melatonin levels rise, and serotonin levels diminish. We begin to feel sleepy and ideally retire for a good night’s rest. It is a perfect system for our needs—unless we stay up beyond biologically natural hours by using artificial lighting.

Then, the phone throws a wrench into the works!

Particularly, a phone, tablet, computer monitor and other electronic device that emits blue light can interfere with sleep cycles. This may leave you wide-awake and staring at the ceiling when you should be sleeping peacefully. Furthermore, you may feel “out of sync” the next day due to lack of rest. We hear a plethora of advice about using blue-blocker screens, and heaven forbid, giving up the devices at night! Regrettably, however, some humans would rather die than not check their devices just before, and many times during, bedtime. Perhaps they are incorrigibly addicted to the phone, tablet, etc. In addition, such activities inhibit melatonin secretion. Best to eschew the phone by night and embrace the sun by day!

So, is there any way to cater to our phone addictions and still get some shut-eye?

An interesting study showed that exposure to constant bright light, for several hours daily, stopped sleeplessness and let melatonin dominate at night. The researchers compared subjects reading a book (no blue light) and a tablet (lots of blue light). They also assessed sleep patterns and melatonin concentrations. Both groups had identical results for melatonin and sleep patterns. From this research, it appears that we can have our cake and eat it too, provided we receive plenty of sunlight. Most noteworthy was that it was not lack of blue light (when the devices were removed) that enhanced sleep. Rather, it was the bright light exposure in the day. Hence, we can evade sleep-deprivation punishment for Love the phone, eschew the phoneexcessive device use if we take our time in the sunlight!

So is there other research indicative of the night-time-sleep-inducing effects of daytime sun exposure?

There are several. For a full discussion, I suggest you read my book, Embrace the Sun, co-authored by Dr. William Grant.

Another investigation established that people whose workplaces have windows are able to sleep about 46 minutes per night longer on average, than those who have no natural light access. Those with windows also are generally happier, have fewer ailments, and experience better vitality than their window-less counterparts.

Why is sleep so important to health, regardless of cell phone, sunlight, etc.?

Another article shows that too little sleep can be deadly. Forbes Magazine online printed an excellent article on sunlight and sleep, which listed the following horrendous statistics: “In 2012, 60 million Americans filled prescriptions for sleeping pills, up from 46 million in 2006.” The article discusses the potential dangers of sleep medications, showing that those who take 18 sleeping pills per year have a tripling of the risk of death compared to those who take fewer than 18.

Do not expect the drug companies to be touting these stats. Take matters in your own hands and get some daily, non-burning sun exposure. In addition, read Embrace the Sun,

Flu: Stop it before it stops you! Sunlight is the key.

Flu: stop it with sunlight. By Marc Sorenson, EdD.

Flu is a killer, and the angst regarding Chinese flu is reason to “enlighten” the world about healing sunlight.

First, the flu is serious and threatening. Tflu taking its tollhe Center for Disease Control (CDC) and others estimate that yearly deaths from flu range from about 12,000-80,000 per year. Additionally, (no surprise here), research also shows that cold and flu outbreaks are almost completely seasonal. In the northern hemisphere, they occur primarily in December through March. In the southern hemisphere, they occur June through September. Therefore, that is almost exclusively in winter in both hemispheres. In addition, the outbreaks in each case occur in times of lowest sun exposure.

Can the shots kill you?

So why not just a flu shot and some aspirin? Because flu shots, along with whatever good they do, can be fatal. One of our friends from California learned this the hard way. His doctors talked him into getting a flu shot to protect him from disease and discomfort. He then contracted a disease called Guillain-Barre (gee-yan-buh-rey) Syndrome.  Loss of muscle strength, loss of or altered sensation, and sometimes paralysis are manifestations of the disease. Our friend had all of those manifestations. He had previously been a hiker, and he enjoyed trekking for up to 100 miles carrying a pack. Guillain-Barre reduced him to a bedridden invalid, and ultimately killed him. Few people succumb to Guillain-Barre, but it seems like a mistake to take the chance. However, I am not telling you not to get a flu shot. That decision is between the patient and doctor.

Stop the the disease by using the most natural method available: regular, non-burning sun exposure.

Personally, the influence of seasons on my tendency to contract colds and flu had a highly significant influence on my interest in sunlight. Until the age of thirty-five, too much of my winter life was spent fighting flu and colds. My first head cold would occur in autumn around mid-November and would keep me in bed two or three days. The illness would then subside over several weeks. Then I would contract whichever flu or cold was in vogue. These ailments took a toll on my life. Most of my friends would suffer one cold per year while nature blessed with up to a half-dozen. Winter was an unhappy time, and I dreamed of leaving the cold weather of the central Nevada-Utah border and moving to warmer climes.

Then came the late spring, summer and early fall. Goodbye flu!

Then came the late spring, summer, anflu: stop it with sunlight.d early fall, when I mostly worked on my father’s ranch. The sun blazed from dawn to dusk and I soaked it up. The work on our ranch was intense. We started those sunny days with morning feeding of animals, followed by irrigating, hauling hay and performing other outdoor tasks. Despite the long hours, I loved the sun, and it made the hard work worthwhile. Whenever possible, my shirt came off, and because of my deep tan, my friends called me “brown man.”

Those were my halcyon days. I was happy and healthy and enjoyed a vigor that was lacking in winter. Later I realized there was never a flu or cold (or any other disease) under the summer sun. Whether this was due to increased vitamin D production of some of the other marvelous additional effects of sun exposure is unknown. Please remember that swallowing a vitamin D capsule can never provide the innumerable benefits of sunlight. BTW, after being a sun-seeker for most of my life, I have never had a skin cancer of any kind. Interesting for an older, blue-eyed, light-skinned Caucasian, who, according to the “experts,” should be a prime prospect for melanoma.

Stop the flu by using the most natural method available: regular, non-burning sun exposure.

The increased incidence of flu and colds during winter associates to sun deprivation. We know that most flu and colds occur in times of low sun exposure.

One of the most recent scientific analyses indicates a profound influence of sun exposure on flu. Researchers tested number of hours of sun exposure per week in Taiwanese children. In addition, they compared that to the incidence of flu among those children. Seven 7 hours of sun per week associated to a 33% reduced risk of influenza hospitalizations. Furthermore, in my opinion, 7 hours is not enough.

Would sunbed use also reduce risk?

Another possibility occurred to me several years ago and influenced my thinking. An elderly friend of mine asked how he could reduce the colds, flu and discomfort he was experiencing each winter. I suggested regular tanning-bed use. He followed the advice and the following winter had no sign of a cold. Either the UV light  protected him against his usual respiratory infections, or it was just luck. The research suggests it was the former, via increased 25(OH)D levels or due to other factors. Vitamin D stimulates the production of anti-microbial peptides that fight infection. For more information on sunbeds, visit this link.

Sunbeds for heath

Sunbeds are unjustly criticized. Learn the truth!

Sunbeds can be healthful devices. By Marc Sorenson, EdD.

Sunbeds, also known as tanning beds, have many healthful properties. They produce vitamin D, strengthen bone and reduce the risk of major cancers. Yet, sunbeds are much maligned as being a major cause of melanoma. Thus, teens in many areas have been banned from using them by misguided legislation. In addition, tanning- salon owners must live in fear of government overreach that could put them out of business.

But new research shows that the attack on sunbeds is misguided.

Because of this uproar, a group of scientists (some dermatologists), led by Dr. Jörg Reichrath, did a thorough research review. Furthermore, they published their findings in the scientific journal Anticancer Research, which presented truth about melanoma and sunbeds. This information is most noteworthy since it is contrary to the prevailing papers that emanate from the Powers of Darkness. The Powers of Darkness are those who love to attack both sun exposure and sunbeds.

Especially relevant points regarding sunbeds and melanoma risk, from Anticancer Research:

  1. First of all, Reichrath and colleagues performed a systematic literature search. This research was undertaken to identify and evaluate research that investigated relationship of solarium use (sunbed use) and melanoma risk. And as a result, they stated the following: “We found no studies that demonstrate a causal relationship between moderate solarium use and melanoma risk.” In addition, they indicated that the quality of the observational studies was low and that bias may have existed.
  2. Another interesting finding was that although moderate sunbed use had no effect on melanoma, something else did affect melanoma. An unhealthy lifestyle involving extensive sunbathing, alcohol and smoking associated to a 20% increase in the disease. Also, the researchers mention that individuals with unhealthful lifestyles use tanning salons more often.

At this time, I must make a point. Those who are regularly in the sun have stronger bones and less cancer than sun avoiders. So I’m not sure what “extensive” sunbathing entailed. And, another point is this: As time spent in the sun has decreased profoundly in both Europe and the U.S., melanoma has increased exponentially. Read my book, Embrace the Sun, to see the discussion on this topic.

Could sunbeds actually decrease the risk of melanoma?

Another salient finding of the research review: A study from Europe showed that sunbed use was associated with a 30% reduced risk for developing melanoma. Reichrath and colleagues made this comment on that study: “Those findings indicate that solarium [sunbed] use may even have a protective effect.”

Sunbeds: beyond melanoma. Here are a few truths about sunbeds that are seldom discussed:

The transcendent sunbed study showed that during 20-years, women who used them reduced all-cause mortality by 23%.  So let’s suppose that that there were some health problems with using sunbeds. That negative possibility pales in comparison to the remarkably reduced risk of death, does it not? And, I am not stating that there were negatives for sunbed use in this research.

What are some of the reasons that sunbed use is associated with a lower risk of all cause death?

Another investigation showed that sunbeds were associated with a reduced the risk of breast cancer.

In addition, research showed that sunbeds were associated with 90% higher vitamin D levels and significantly stronger bones.

Also, they are useful in treating psoriasis and other skin disorders.

Sunbeds are also useful in treating pain and in improving mood.

Finally, these devices have been shown to associate with lower clot risk.

The takeaway from all of these studies is that there is no credible research that melanoma is increased by using sunbeds. And, sunbeds have remarkably healthful effects. When receiving sun exposure or using sunbeds, be sure not to burn.

Happy sunning!

Sunlight and health

Sunlight or vitamin D or both? Sunlight is the answer.

Sunlight or vitamin D or both? By Marc Sorenson, EdD.

Sunlight or vitamin D? That is a question that should not be necessary, yet many believe that vitamin D replaces sun exposure. So, they will state, “just take some vitamin D pills rather than go out in the sunlight, thus, you can derive sunlight benefits without the risk of skin cancer.” This opinion is incorrect, and it leads to sun deprivation.

This poor opinion of sunlight is misguided, erroneous and dangerous.

First of all, sunlight leads to production of many photoproducts when it touches the skin or enters the eyes. (Do not stare into the sun, since sufficient sun enters the eyes by reflection from objects or from the sky). These photoproducts include serotonin, endorphin, vitamin D, dopamine, brain-derived neurotropic factor (BDNF) and nitric oxide.

Furthermore, all of these sunlight photoproducts are known to have healthful effects.

In addition, there are more photoproducts that are produced by sun exposure, but they have not yet been well-studied. Yet, it is likely that all of them will be found to have salubrious effects for the human body. Hence, we need them all. Obviously, a vitamin D pill cannot provide all the health benefits that sunlight provides.

Vitamin D in isolation may not always be healthful. Consider sunlight instead.

So yes, vitamin D is an important photoproduct of sunlight, but it is just one of the photoproducts. Thus, it is along for the ride with its companions. The serum blood tests which measure vitamin D are really surrogate measures for sunlight exposure and its other photoproducts. And, these photoproducts work as a team; one might say a “holistic” team.

Sunlight or vitamin D. What does the vitamin D research tell us?

A surprising piece of recent research assessed the efficacy of vitamin D supplementation on bone strength and density. The researchers worked with 311 healthy volunteers aged 55 to 70 and these volunteers were split into three groups. One group received 400 international units (IU) per day of vitamin D, and a second group received 4,000 IU per day. Finally, a third group received 10,000 IU per day. Bone strength and density were measured at the beginning of the investigation and at intervals of 6, 12, 24 and 36 months. The researchers had thought there would be an increase in bone mass, yet, the results were opposite of their expectations. Stunningly, all three groups lost bone mass, and the higher the vitamin D dose, the more rapid the bone loss!

How can this happen? Does sunlight exposure play a part?

So, we have an interesting dichotomy here. First of all, we see that isolated vitamin D (the supplements) were counterproductive for bone strength and mass. And yet, we know that low serum levels of vitamin D are associated with low bone density. Maybe we can unravel this mystery by mentioning that almost all serum vitamin D (about 90%) is produced by sun exposure on the skin.

Therefore, low vitamin D levels are really indicative of sunlight deprivation.

And as aforementioned, one isolated chemical (vitamin D), cannot possibly be expected to take the place of the holistic sun. Especially relevant is a study that found Spanish women who sunbathed had 1/11 the fracture risk of indoor women. Is there any doubt that the strong-boned women had higher vitamin D levels than their counterparts? You see, we have gotten it backward, because greater sun exposure associates with higher vitamin D levels and predicts long life and health. Sunlight leads to vitamin D production, but vitamin D does not bring sunlight and all its additional photoproducts.

Does vitamin D supplementation protect against cardiovascular disease (CVD), or is it sunlight?

We know the answer to half of that that question due to a study of more than 83,000 people. And this study was a meta-analysis. This means a compilation and analysis of the best supplementation studies. The study compared vitamin D intake with CVD events (heart attacks, stoke, death from CVD and all-cause death). The authors found, as a result, that vitamin D supplementation was not associated with CVD.

Most noteworthy is that for years, sunlight was shown to associate to a much reduced risk of CVD.

And, that included heart attack and stroke.
Many made the mistake of giving the credit for the reduced risk to vitamin D, because of this research.The answer to health is to embrace the holistic sun and not a single photoproduct.

Sunlight related to the beta carotene study

This reminds me of research on beta-carotene, an antioxidant nutrient found in orange and yellow vegetables such as carrots. Since these vegetables have healthful properties, the researchers decided to experiment with isolated beta-carotene. They wanted determine if beta-carotene also had anti-cancer properties. To their dismay, these experiments associated to an increase in cancer. Does isolated vitamin D lead to the same deleterious outcomes? Sunlight should also be used in its whole form, just like the carrot.

So in the winter, in climes where there is little sunlight, how do we get our share of life-saving light?

The best method is to use a good sunbed (tanning bed), and when the sunlight is available, to be outside enjoying it, summer and winter. Sunbed use has many life-enhancing effects, including longer life, stronger bones and better mood.

Happy sunning! And remember never to burn.

Protect the children with sunshine #7. Arthritis

Protect the children with sunshine. By Marc Sorenson, EdD.

Protect the children against illness? That is a great idea, and sunshine is one of the most effective “protectors” we can use.

“Children and arthritis” is not something we hear about because arthritis is thought to be an adult’s disease. Yet tragically, an estimated 294,000 children under age 18 have some form of arthritis or rheumatic condition. And this represents approximately 1 in every 250 children in the US.[1] Thus, we must be concerned and promote actions that protect the children.

Do we need to be even more concerned to protect the children in northern climes?

Also, the numbers of children with arthritis increase dramatically In Canada and the Northern U.S. This could be as a result of either vitamin D deficiency or sunlight deficiency or both. Since 90% of vitamin D blood levels are due to sunlight, it is likely that sun deprivation is the cause. So, if our desire is to protect the children, we must insist that they receive plenty of non-burning sun exposure. And in the winter, a vitamin-D producing sunlamp should be the first choice. When we use lamps to produce vitamin D, we also protect the children with other critically important photoproducts. Some of these photoproducts are endorphins, serotonin, nitric oxide brain-derived neurotropic factor (BDNF), dopamine and endorphin. And all of these photoproducts are necessary for health. So, to help the children, we should be sure that they have ample sunshine or light for the aforementioned sun lamps.

Articles from the UK and scientific journals help us to protect the children.

An article from the Express, a UK online newspaper, describes research published in the scientific journal, Annals of the Rheumatic Diseases. They state, “Millions of people could protect themselves from crippling arthritis by getting a regular dose of sunshine.” And although the research involved women, we can easily extrapolate to children, since mothers to a great extent, determine their children’s habits.

To learn more about arthritis and the influence of sun exposure, read this article (and others) posted on Sunlight Institute. First of all, go to the news section and search “arthritis.” You will find numerous articles on the subject. Also, read the book, Embrace the Sun.

Remember to obtain regular sun exposure to protect yourself and to protect the children. Happy sunning!

Children’s diseases associated with sun deprivation. #6

Children’s diseases associated with sun deprivation. by Marc Sorenson, EdD

Children’s diseases that are associated with sun deprivation are legion. So, how do I know this? Because my last five blogs discussed this topic, and I’m a long way from finishing the theme.

To subject our children to sun deprivation is child abuse. It results in either lifelong or temporary children’s diseases.

So, the first of the children’s diseases discussed this week will be acute lower respiratory infections (ALRI). In addition, the second will be attention deficit hyperactivity disorder (ADHD).

ALRI are a leading cause of sickness and mortality both in children and adults worldwide. Furthermore, ALRI are not uniformly defined and this may hamper a true appreciation of their importance. Also, from an epidemiological point of view, the definition of acute lower respiratory infections includes other diseases. The most noteworthy of these diseases are acute bronchitis and bronchiolitis, influenza and pneumonia. The NCBI also states that acute respiratory infections, and particularly lower respiratory tract infections are deadly. Another fact is that these diseases are the leading cause of death among children under five years of age.  Especially relevant is that they are estimated to be responsible for between 1.9 million and 2.2 million childhood deaths globally.

Studies regarding children’s diseases indicate that sun exposure has protective effects, whether due to vitamin D production or another factor.

First of all, in one study, children placed outside in sunlight were less than half as likely to suffer ALRI. Another investigation on sunlight compared vitamin D levels and sun exposure habits in children with and without ALRI. And, there was virtually no difference in vitamin D levels between the sick and healthy groups. Yet, those children who had a higher percentage of the body exposed to sunlight were less likely to have ALRI. Therefore, this reinforces the fact that sun exposure has preventive effects beyond vitamin D for children’s diseases.


ADHD (attention deficit hyperactivity disorder) is another of the disheartening children’s diseases.

ADHD is the most prevalent of mental disorders in children. And, it causes significant problems with executive functions (e.g. attentional control and inhibitory control). In addition, it causes attention deficits, hyperactivity, or impulsiveness not appropriate for a person’s age. Thus, it is certainly another of the important children’s diseases. Also, researchers have found that sun exposure correlates to a decreased risk of ADHD. The investigators assessed the relationship between ADHD prevalence and sun intensity in various nations and in US states. As a result, they found a close association between low sunlight intensity and the prevalence of ADHD. Another finding was that it explained 34%–57% of the variance in ADHD prevalence, with high sunlight intensity having a preventive effect.

It seems like the advice to deprive our children of sun exposure, in order to a prevent melanoma, is disastrous. Do we want to increase the chance of ALRI, ADHD or other children’s diseases we have already discussed? In conclusion, let’s love our children and be sure that they receive plenty of regular, non-burning sun exposure. And for more information, read the book, Embrace the Sun.

Happy sunning!
