Dermatologists Fuel Chronic Disease Rates with
Their Flawed Sun Exposure Guidelines
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: 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, arthritis, stroke, and cardiovascular disease. Recent research shows that raising maternal vitamin D levels helps children born in winter months develop stronger, healthier bones. 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. 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: 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. 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. Dr. Joseph Mercola was trained by the conventional model. In his first years of private practice, he treated many symptoms with prescription drugs and was actually a paid speaker for the drug companies. But as he began to experience the failures of this model in his practice, he embraced natural medicine and has had an opportunity over the last thirty years to apply these time-tested approaches successfully with thousands of patients in his clinic. Over 16 years ago he founded Mercola.com to share his experiences with others. The site is the most visited natural health site in the world for the last seven years with nearly two million subscribers. He’s also written two NY Times bestselling books, and has had frequent appearances on national media. Visit: www.mercola.com |
