Importance of Vitamin D & The Sun

How Dermatologists Fuel Chronic Disease Rates With Their Flawed Sun Exposure Guidelines

Story at-a-glance

  • The U.S. Surgeon General, the American Academy of Dermatology, and The Skin Cancer Foundation all view sunlight irrationally as a dangerous skin cancer risk
  • Sun avoidance fuels health problems associated with vitamin D deficiency, including hypertension, cardiovascular disease, cancer, depression, and poses special health risks to pregnant mothers and their children
  • The evidence supporting sensible sun exposure is strong and clear, while there’s little evidence that sunscreen use protects against skin cancer, or that vitamin D supplements are bioequivalent to sunshine

By Dr. Mercola

In July 2014, the interim U.S. Surgeon General Dr. Boris Lushniak, who is also a dermatologist, issued a “Call to Action to Prevent Skin Cancer,”1,2 in which he declared UV radiation harmful and said sun exposure should be avoided altogether.

The American Academy of Dermatology and The Skin Cancer Foundation also advocate avoiding all sun exposure — regardless of the color of your skin — saying vitamin D supplementation can address any deficiencies.

This is an irrational and shortsighted position that lacks any credibility. The scientific evidence, now running in excess of 34,000 studies, detail that UV exposure is essential, both for vitamin D production and other benefits unrelated to vitamin D.

The color of your skin is a significant factor to determine appropriate exposure times and any advice that does not take this into consideration is illogical.  We are not nocturnal beings, avoiding the sun entirely is horrible advice that should not be followed.

Dermatologists’ Position on Sun Exposure Riddled With Fatal Flaws

Let’s remember that, because of their irrational concern, they were able to convince public health officials and media to convince people to use sunscreens.

What happened as a result of the public adopting this proactive “preventive” approach? Skin cancers actually increased.

Why? Because the dermatologists did not do their homework. Most sunscreens blocked UVB, which causes vitamin D levels to increase and lower cancer rates, but they let UVA, which can cause skin cancer when excessively exposed, to shine right through like a hot knife through butter.

What’s worse, they never admitted to their egregious mistake. Ironically,  the only location dermatologists approve of UV light treatment is in their office under costly supervision.

Avoiding Sun Exposure Radically Worsens Disease Rates

Advocating abstinence from UV light is undoubtedly fueling many health problems associated with vitamin D deficiency, including cancer, cardiovascular disease, autoimmune diseases and depression.

UVB exposure is essential for optimal health, and any risks of exposure are related to over exposure and burning. Research shows vitamin D is involved in the biochemical regulation of nearly every cell in your body, including your immune system.

Vitamin D deficiency can deteriorate your health in a number of different ways, as your cells need the active form of vitamin D to optimally regulate genetic expression.

As noted by William Grant, Ph.D., head of the Sunlight, Nutrition and Health Research Center (SUNARC), staying indoors to avoid sun exposure is “not particularly good advice,” adding that:3

“There are several papers indicating that occupational exposure to sunlight reduces the risk of melanoma. It is having fair skin, a high-fat, low fruit and vegetable diet, sunburning, etc., that are more linked to melanoma than total UV exposure.”

Vitamin D Is Crucial for Pregnant Women

Vitamin D is particularly important for pregnant women, as deficiency affects both the mother and her child in the short and long term, including raising the child’s long-term risk for diabetes, allergic rhinitis,4 arthritis, stroke, and cardiovascular disease.Recent research shows that raising maternal vitamin D levels helps children born in winter months develop stronger, healthier bones.5 Lead researcher Professor Nicholas Harvey, Ph.D., of the University of Southampton, also notes that sun exposure is the most important source of vitamin D.

Health initiatives such as GrassrootsHealth D*Action study,6 and the Protect Our Children NOW! campaign are both based on these fundamental and scientifically proven facts.

Dermatologists Ignore Skin Color

The fact that the American Academy of Dermatology issues the same recommendations for everyone, without regard for skin type, is telling. Despite overwhelming evidence to the contrary, they view sun exposure as nothing but a dangerous cancer risk to be avoided at all costs.

This is a really nonsensical, and most definitively nonscientific, stance. According to their advice, even if you have the darkest skin, you should always seek shade and wear protective clothing and/or sunscreen when outdoors.

The notion that supplements are bioequivalent to sunshine is lacking.  While I recommend supplements if UVB exposure is not available, to suggest that vitamin D can replace all the benefits of sun exposure is ridiculous.

In fact, each of us responds quite differently to vitamin D supplementation – there is a 6 to 10 times difference in dosage response between individuals.   If you are supplementing with vitamin D, you should have your levels checked twice per year to ensure you stay above 40ng/ml.

Because of this, vitamin D experts such as Grant and Dr. Michael F. Holick note that sensible sun exposure is far preferable to vitamin D supplementation.

Oversimplifying the Issue Is Not a Good Public Health Policy

The Skin Cancer Foundation echoes the American Academy of Dermatology’s recommendations.

When questioned about this philosophy and asked why the recommendations fail to take into account skin type and color, Dr. Henry Lim, who sits on The Skin Cancer Foundation’s photobiology committee, replied that such information is irrelevant because vitamin D supplements can address deficiency.

According to Lim:7

“We want to make it simple as a public health message — as to what the public should reasonably be able to absorb and understand. To fine tune it is just too complicated we feel.”

But by oversimplifying the matter, dermatologists place a great number of people at grave risk for vitamin D deficiency, which may not be identified until health problems have already set in. Moreover, the advice to use sunscreen is also on shaky scientific ground.

According to an analysis by epidemiologist Marianne Berwick, Ph.D., there’s very little evidence to suggest that sunscreen use will prevent skin cancer.

After analyzing a dozen studies on basal cell carcinoma, which is typically non-lethal, and the more deadly melanoma, Berwick found that people who use sunscreen tend to be more likely to develop both of these conditions.

Only 2 of 10 melanoma studies found that sunscreen was protective against this condition; three found no association either way. None found sunscreen use protected against basal cell carcinoma.8

Your Body Is Designed to Optimize Health Effects of Sun Exposure

While you certainly need to avoid the skin damage associated with sunburn, sun exposure is required for optimal health, and your skin type plays a major role in how much UVB exposure you need and can safely tolerate.

Darker-skinned people not only need more sun exposure to produce sufficient amounts of vitamin D, they’re also more protected from skin cancer due to their skin pigmentation. Yet this important reality is simply ignored by dermatologists, resulting in most African Americans being at a radically increased risk of cancers and heart disease from vitamin D deficiency.

As noted in a previous article by Nautilus:9

“How the sun affects you depends on your complexion, the shade of which is determined by melanin … The anti-oxidizing molecule is so versatile at protecting and repairing DNA from UV solar radiation that creatures from humans to fungi deploy it … [T]he melanin sits atop cellular DNA like tiny umbrellas pointed … out to shield from incoming rays …

[T]he same ultraviolet wavelengths in the 290 to 400 nanometers range that trigger melanin production also spark vitamin D creation. You cannot make one without the other.

Humans evolved to produce two kinds of melanin … The MC1R gene determines the type of melanin the body produces. In the mid-zone such as the Mediterranean region, people … produce eumelanin, the pigment responsible for brown or black hair and for dark skin that tans easily …

[I]n far northern Europe, humans paled, adapting to lower light … with a different type of melanin, called pheomelanin, associated with fair skin and blonde and red hair with minimal protective value, but allowing more UV to penetrate to make vitamin D. ”

Sun Avoidance Raises Risk of Internal Cancers

Dermatology is focused on one primary outcome — avoiding skin damage and skin cancer. But by focusing on just one side of the UV exposure issue, they’re actually promoting a lifestyle that may raise your risk of other lethal cancers and chronic diseases. Not only have higher vitamin D levels been shown to offer significant protection against a number of internal cancers, there’s also evidence showing higher levels offer protection against melanoma.

In fact, higher rates of melanoma are found among those who have low vitamin D levels; among indoor occupations; and in areas of the body that rarely or never see the light of day. In short, the vitamin D your body produces in response to UVB radiation is protective against skin cancer. As noted in The Lancet:10

“Paradoxically, outdoor workers have a decreased risk of melanoma compared with indoor workers, suggesting that chronic sunlight exposure can have a protective effect.”

Even more importantly, vitamin D has been shown to significantly reduce internal cancers, along with chronic diseases such as heart disease, which kill far more people than melanoma does. Breast11 and prostate12,13 cancers are just two examples where low vitamin D renders you more vulnerable to more aggressive forms of the disease. Recent research14 has also found that low vitamin D levels are associated with more severe peripheral neuropathy in cancer patients.

Reporting on recent research linking low vitamin D levels to an increased risk for aggressive breast cancer, Medical Daily writes:15

“The researchers linked vitamin D levels to the ID1 gene, which at high levels of expression is associated with breast cancer tumor growth. Past studies have shown that vitamin D is linked to inhibiting the expression of this gene, and that low vitamin D levels have been associated with more aggressive tumors. ”

Public Health Messages Should Be Based on All-Cause Mortality Reduction

The Importance of Being in The Sun

Why avoiding sunshine could kill you

Researchers followed 30,000 women for 20 years and found that those who avoided the sunshine were twice as likely to die

Too little sunshine dramatically increases the risk of dying from all causes because the body is deprived for vitamin D, scientists have found

Women who never sunbathe during the summer are twice as likely to die than those who sunbathe everyday, a major study has shown.

Researchers at the Karolinska Institute in Sweden claim guidelines which advise people to stay out of the sun unless wearing sunscreen may be harming the population, particularly in countries like Britain.

Exposure to ultraviolet radiation from sunlight is often cited as a cause of skin melanoma. The NHS currently recommends avoiding overexposure to the sun to prevent all types of skin cancer.

But the new research, which followed nearly 30,000 women over 20 years, suggests that women who stay out of the sun are at increased risk of skin melanomas and are twice as likely to die from any cause, including cancer.

“The results of this study clearly showed that mortality was about double in women who avoided sun exposure compared to the highest exposure group,” said lead author Dr Pelle Lindqvist.

“Sun exposure advice which is very restrictive in countries with low solar intensity might in fact be harmful for women’s health.

“The mortality rate was increased two-fold among avoiders of sun exposure as compared to those with the highest sun exposure habits.”

It is thought that a lack of vitamin D may to be blame. Vitamin D is created in the body through exposure to sunshine and a deficiency is known to increase the risk of diabetes, tuberculosis, multiple sclerosis and rickets.

Cases of rickets have risen fourfold in the last 15 years as sunscreen has increased in popularity.

Previous studies have shown that vitamin D can increase survival rates for women with breast cancer while deficiencies can signal prostate cancer in men. Low levels of vitamin D have also been linked to more aggressive forms of skin cancer.

Prof Dorothy Bennett, Professor of Cell Biology at St. George’s, University of London, said: “The findings support the consensus that the ideal amount of sun exposure for Northern Europeans is ‘a little’, rather than zero.

“As the authors comment, our bodies need sunlight to make essential vitamin D, which can help us resist some cancer types. Those who normally avoid the sun and/or cover most of their skin are advised to take vitamin D supplements.”

The study looked at 29,518 Swedish women who were recruited from 1990 to 1992 and asked to monitor their sunbathing and tanning salon habits.

After 20 years there had been 2,545, deaths and researchers were surprised to find that women who never sunbathed during the summer months were twice as likely to have died from any cause.

1.5 women in a 100 who had the highest exposure to UV were found to have died, compared with 3 in 100 for women who had avoided sunbathing.

Women who sunbathed in the summer were also 10 per cent less likely to die from skin cancer although those who sunbathed abroad were twice as likely to die from melanoma.

Public Health England says it would be considering the research carefully.

A spokesman said: “Public Health England constantly reviews scientific research and our experts will consider this paper along with other peer reviewed research into this issue as part of that process.”

Dr Andrea Darling, Post-doctoral Research Fellow from the University of Surrey, said there was still strong evidence that skin cancer is caused by sunbathing.

“The findings from Dr Lindqvist’s team are interesting, but it is possible that the women in the study who had high sun exposure differed from the women who had low sun exposure in ways that may explain their reduced cancer risk.”

Yinka Ebo, senior health information officer at Cancer Research UK, said striking a balance was important.

“The reasons behind higher death rates in women with lower sun exposure are still unexplained, as unhealthy lifestyle choices could have played a part,” she added.

“Overexposure to UV radiation from the sun or sunbeds is the main cause of skin cancer.

“We all need some sunshine to make vitamin D for healthy bones. Enjoying the sun safely while taking care not to burn should help most people strike a good balance.”

A spokesman for the Department of Health said: “Skin cancer can have devastating consequences and it is vital that people take steps to protect themselves.

“However, we also recognise the importance of Vitamin D for good health. Most people in the UK can get enough vitamin D from sunlight, but those at risk of vitamin D deficiency should take daily supplements.

“We are working to raise awareness of the symptoms of cancers through the Be Clear on Cancer campaigns. Anybody concerned about symptoms should visit their GP.”

The research was published in The Journal of Internal Medicine.

Know Your Sunscreen

7 Important Issues You Need To Know About Sunscreen

By NaturalNews

Ask somebody about sunscreen and you’re likely to receive an earful of disinformation from a person who has been repeatedly misinformed by health authorities and the mainstream media. Almost nothing you hear about sunscreen from traditional media channels is accurate. So here’s a quick guide to the 7 most important things you need to know about sunscreen, sunlight and vitamin D:

#1) The FDA refuses to allow natural sunscreen ingredients to be used in sunblock / sunscreen products.

It’s true: If you create a truly natural sunscreen product using exotic botanicals with powerful sunscreen properties, you will never be able to market it as a “sunscreen” product. That’s because the FDA decides what can be used as sunscreen and what can’t, regardless of what really works in the real world. And there are really only two natural ingredients the FDA has allowed to be sold as sunscreen: Zinc oxide and titanium dioxide.

Any other non-chemical sunscreen ingredients, if sold as “sunscreen,” would be considered mislabeled by the FDA and result in your products being confiscated… even if they offer fantastic sunscreen protection!

Not surprisingly, this whole monopoly over sunscreen chemicals is designed to protect the profits of the chemical companies while marginalizing the natural product companies which could easily formulate far better solutions. I have personally spoken to the founders of several health product companies who have figured out amazing sunscreen formulations using nothing but natural botanicals, but the FDA won’t let them market their products as sunscreen products! It’s just another example of the FDA standing in the way of health innovation.

#2) Nearly all conventional sunscreen products contain cancer-causing chemicals.

Read the ingredients list of any sunscreen product sold at Wal-Mart, or Walgreens, or any other mainstream store.

You will not be able to pronounce most of the chemicals found in the ingredients list. That’s because most sunscreen products are formulated with cancer-causing fragrance chemicals, parabens, harsh alcohols, toxic chemical solvents and petroleum oils. A typical sunscreen product is actually a chemical assault on your body. That’s why research shows that using sunscreen actually causes more cancer than it prevents (http://www.naturalnews.com/023317_s…)

#3) In the US where over 70% of the population is vitamin D deficiency, sunscreen actually blocks vitamin D production.

Vitamin D deficiency is perhaps the most widespread vitamin deficiency in North America. According to the research, 70 percent of whites are deficient in vitamin D, and up to 97 percent of blacks are deficient (http://www.naturalnews.com/030598_v…).

Chronic vitamin D deficiency promotes cancer (http://www.naturalnews.com/031560_v…), winter flu and infections, depression, osteoporosis and hormonal imbalances. Depending on whom you believe, vitamin D alone can prevent anywhere from 50% to nearly 80% of all cancers (http://www.naturalnews.com/021892.html).

By blocking vitamin D production in the skin, sunscreen products actually contribute to cancer-promoting nutritional deficiencies.

This doesn’t mean you should never wear a sunscreen product, of course. If your skin is really pale and you’re planning a day on the beach in Hawaii, you will obviously benefit from some level of sun protection using a truly natural sunscreen product. But an informed health-conscious person would try to allow their skin to achieve a natural, healthy tan (yes, a tan truly is healthy if it’s combined with good nutrition, see below) through sensible exposure levels that activate vitamin D production in the skin.

#4) You can boost your internal sun resistance by changing what you eat.

Here’s the real secret about sun exposure that no one in conventional medicine is talking about (because, as usual, they are woefully ignorant about nutrition): You can boost your internal sunscreen by eating antioxidant-rich foods and super foods.

The supplement astaxanthin, for example, is very well known for boosting your skin’s natural resistance to sunburn. Its fat-soluble carotenoids are actually transported to skin cells where they protect those cells from UV exposure.

The more natural antioxidants you have in your diet, the more sunlight your skin will be able to handle without burning. Nearly everyone mistakenly believes that a person’s sunlight burn response is purely a genetic factor. They’re wrong. You can radically improve your resistance to UV exposure through radical dietary changes.

I’m a great example of this, actually, as I used to burn in just 20 – 30 minutes of sunlight when I was on a junk food diet years ago. But now, as someone who eats superfoods and high-end nutritional supplements every day, I can spend hours in the sun and will only turn slightly red (which fades a few hours later and does not result in a burn or skin peeling).

Except for one time on an all-day visit to a water park, I have not worn sunscreen in over 8 years. I spend a large amount of time in the sun, and I have absolutely no concerns whatsoever about skin cancer. My skin, most people tell me, looks significantly younger than my biological age. That’s not from sunscreen; it’s from nutrition. Sun exposure does not make your skin “age” if you follow a high-nutritional density diet.

The below video is about “The Truth About Sunlight, Cancer and Vitamin D”
by the Health Ranger from Natural News.

#5) UV exposure alone does not cause skin cancer.

It is a complete medical myth that “UV exposure causes skin cancer.” This false idea is a total fabrication by the ignorant medical community (dermatologists) and the profit-driven sunscreen companies.

The truth is actually more complicated: Skin cancer can only be caused when UV exposure is combined with chronic nutritional deficiencies that create skin vulnerabilities.
To create skin cancer, in other words, you have to eat a junk food diet, avoid protective antioxidants, and then also experience excessive UV exposure. All three of those elements are required. Conventional medicine completely ignores the dietary influences and focuses entirely on just one factor: Sunscreen vs. no sunscreen. This is a one-dimensional approach to the issue that’s grossly oversimplified to the point of being misleading.

The medical industry, it seems, does not want people to figure out they can literally eat their way to healthier skin. It’s amazing, actually: Your skin is made entirely out of the food you eat, so how could your diet not affect your skin health? Yet no one in conventional medicine — not the dermatologists, not the doctors and not the health regulators — has the intellectual honesty to admit that what you eat largely determines how your skin reacts to UV exposure.

#6) Not all “natural” sunscreen products are really natural.

Be careful when shopping for so-called “natural” sunscreen products. While there are some good ones out there, many are just examples of greenwashing, where they use terms like “natural” or “organic” but still contain loads of synthetic chemicals anyway.

A good guide for checking on sunscreen products is the Environmental Working Group guide (EWG) at: http://www.ewg.org/skindeep/

Some of the products that are truly natural include Loving Naturals sunscreen and Badger All Natural Sunscreen. Read the ingredients labels to see for yourself. Don’t use any sunscreen product containing ingredients that sound like chemicals:
• Methyl…
• Propyl…
• Butyl…
• Ethyl…
• Trieth…
• Dieth…etc.
Always buy unscented sunscreen unless for some reason you just enjoy coating your skin with artificial perfume chemicals. A typical sunscreen product is made with over a dozen cancer-causing fragrance chemicals, and they’re absorbed right through your skin. Most sunscreens, when applied as directed, are really just toxic chemical baths that heavily burden your liver and can give you cancer.

#7) Many “chemical free” sunscreens are loaded with chemicals.

Search Amazon.com for “chemical free natural sunscreen” and you’ll see a listing for:
Jason Natural Cosmetics – Earth’s Best Sun Block Chemical Free, 4 oz cream
Click on the product and you’ll find a listing of its ingredients which includes: C12-15 Alkyl Benzoate, Caprylic/Capric Triglyceride, Sorbitan Isostearate, Sorbitan Sesquioleate, Ethylhexyl Palmitate, Ethyl Macadamiate, Calcium Starch Octenylsuccinate, Stearalkonium Hectorite
So how are those not chemicals? Ethylhexyl Palmitate is NOT a chemical? Who are these people kidding? The Amazon.com description (title) of this product is false and misleading. In all fairness, however, this product title looks like it was added into the Amazon.com system by the vendor and not the Jason company itself. But it’s an example of how the information you see from online vendors can often be misleading.
Always read the ingredients of any sunscreen product before using it. Don’t poison yourself with sunscreen!

Beware the disinfo minefield surrounding sunscreen products

Perhaps more with sunscreen than any other personal care product, the “official” information distributed through the mainstream media is hopelessly misleading (if not downright false). Remarkably, no one in the media or the government is even willing to admit that fragrance chemicals are bad for your health. Similarly, no one is willing to admit that the chemicals you put on your skin get ABSORBED by your skin.

Without those two truths being acknowledged right up front, the rest of whatever they say about sunscreen is worthless babble. Any honest talk about sunscreen must acknowledge the simple truth that the chemicals you put on your skin get absorbed into your skin, and that most sunscreen products are made out of a chemical cocktail of cancer-causing substances.

This is the truth about sunscreen that both the sunscreen industry and the cancer industry doesn’t want you to hear. It’s the dirty little secret of sunscreen: The more you use, the more you CAUSE cancer in your body! (And the more money the cancer centers make “treating” your cancer with yet more deadly chemicals known as chemotherapy.)

So buyer beware. Sunscreen products are a minefield of lies, fraud and disinformation designed to keep you ignorant of the importance of sun exposure as well as the health risks associated with using cancer-causing chemicals on your skin.

Stick with truly natural sunscreen products (when needed) and try to build up a healthy tan while consuming large quantities of superfoods and antioxidants in your diet. Consider taking astaxanthin or other fat-soluble nutrients on a regular basis. Engage in daily juicing of fresh fruits and vegetables which are loaded with living nutrients. Time your sun exposure to build up a healthy tan so that you don’t need sunscreen at all. Contrary to all the misinformation we’ve all been fed, a healthy tan is actually a good sign that you’re achieving adequate vitamin D synthesis in your own skin
