An excellent paper by Dr. Hoel and Dr. de Gruijl is titled “Sun Exposure Public Health Directives.” It decries the vilification of sunlight and suggests people return to its healthful rays.
So is dermatology awakening to the truth about sunlight?
One of the authors, Dr. de Gruijl, works at a dermatology department in the Netherlands. He is also a photobiologist and melanoma skin cancer research specialist. It seems like the dermatology world is returning to common sense, since other dermatologists have lately suggested more sunlight exposure. And well they should suggest more sunlight! Sunlight can save millions of lives, yet much of the population is dying in the dark due to misinformation. Many dermatologists consider sunlight exposure to be a killer, and thus frighten their patients away from sun exposure. Why? Because they are fearful of skin damage from sunlight, something they need not fear if they advise their patients properly.
Sunlight and skin cancer: the truth
One of my pet peeves is the statement that “sunlight causes cancer.” First of all, there are about 18 major cancers that are reduced by sunlight. And in addition, there are also myriad non-cancer maladies that are reduced or eliminated by safe sun exposure. These disorders run the gamut from arthritis and heart disease to psoriasis, erectile dysfunction and osteoporosis. Secondly, not even skin cancer is caused by sun exposure unless people burn themselves. Therefore, it is a lack of both caution and common sense that leads to skin damage. The authors state that the public has been taught that health benefits of sun exposure are limited to bone health. That is another egregious error (italics mine).
The aforementioned paper reads almost like a synopsis of Embrace the Sun, the book by Marc Sorenson and William Grant,
Here are the major points on sunlight that make the research in the paper so compelling:
I agree and would like to reiterate that vitamin D supplements are not an adequate substitute for sunlight. Consequently, these measurements should be used only among those who do not take supplements. That is, if we expect to really measure sunlight exposure.
