Unverified reports claiming that unprotected, intentional sun exposure is necessary for Vitamin D formation are getting quite a bit of media coverage lately.
Yet, dermatologists standing advise the in the public eye to practice sun protection to prevent skin cancer.
At a recent American Academy of Dermatology’s Skin Cancer Detection and Prevention Month news conference, dermatologist Darrell S. Rigel, M.D., clinical professor, spic-and-span York University Medical Center in spic-and-span York City, debunked the myths close Vitamin D and offered advice on getting an satisfactory dose of this nutrient.
“As a dermatologist who treats the ravages of skin cancer on a daily basis, it is appalling to me that anyone in good conscience could make the claim that intended sun exposure – for any length of time – is beneficial,” explicit Dr. Rigel. “The fact is, skin cancer is incorporative at an forbidding rate and technological research confirms that our best defense is avoiding excessive, unprotected sun exposure.”
Dr. Rigel addressed the following myths active vitamin D and sun exposure:
Myth #1 – Sunscreen blocks Ultraviolet (UV) light. Consequently, UV radiation is prevented from reaching the skin, which leads to an inadequate amount of vitamin D in the body.
Fact – A 1997 study published in the Journal of the National Cancer Institute of patients with Xeroderma Pigmentosa (a disease that predisposes persons to skin cancer who are exposed to very low levels of ultraviolet radiation), showed that these patients have mean vitamin D levels despite negligible amounts of UV exposure.
Myth #2 –A considerable amount of UV exposure is necessary to maintain normal levels of vitamin D.
Fact – Normal vitamin D levels are preserved through a mean diet.
Myth #3 – Sunscreen does not allow UV radiation to reach the skin, so if people wear sunscreen, their bodies can form vitamin D.
Fact – equal the best sunscreen cannot block complete UV radiation. But the amount that does hit the skin is sufficient to promote satisfactory vitamin D formation.
Myth #4 – Skin cancer is not a grave disease, so sun protection is not important.
Fact – cardinal American dies all hour from melanoma, the most grave form of skin cancer.
Myth #5 – Low levels of Vitamin D lead to much cancers and opposite diseases.
Fact – “There are no technological studies that prove this statement,” explained Dr. Rigel. “The claim is supported on a study that finds that overall cancer rates are higher in the northeast cohesive States, a location with lower sunlight levels than galore other places in the country. Those making this claim conclude that since the northeast has lower UV levels, this is the reason why cancer rates are high in this region. However, several studies prove this theory is false. These include studies that show that cancer rates are contrabass in the north plain states (areas with the worst UV levels in the country) and small regional studies (New York state), where cancer rates are highest in areas with progressive pollutants and are not related to sunlight levels.”
“When we take a close look at these myths and evaluate the facts, the course of action is clear,” said Dr. Rigel. “Until there is science that tells us otherwise, it is imperative that people protect themselves from the sun. Anyone concerned active not getting sufficient vitamin D should either take a multivitamin or drink a few glasses of vitamin D-fortified milk every day. Given the fact that the U.S. Department of Health and Human Services has declared UV radiation as a known carcinogen, exposing oneself to it for the sake of vitamin D is not the answer.”
The American Academy of Dermatology advises everyone to engage in the favourable sun protective practices:
- avoid outdoor activities between 10 antemeridian and 4 postmeridian when the sun’s rays are the strongest.
- seek shade whenever possible.
- wear a broad-spectrum sunscreen with a Sun Protection Factor (SPF) of at least 15.
- reapply sunscreen every two hours.
- wear sun-protective clothing.
