From Activist Post:
Our biological connection and dependence on the sun is so profound, that the very variation in human skin color from African, melanin-saturated dark skin, to the relatively melanin de-pigmented, Caucasian lighter-skin, is a byproduct of the offspring of our last common ancestor from Africa (as determined by mitochondrial DNA) migrating towards sunlight-impoverished higher latitudes, which began approximately 60,000 years ago.
In order to compensate for the lower availability of sunlight, the body rapidly adjusted, essentially requiring the removal of the natural "sunscreen" melanin from the skin, which interferes with vitamin D production; vitamin D, of course, is involved in the regulation of over 2,000 genes, and therefore is more like a hormone, without which our entire genetic infrastructure becomes destabilized.
While the health benefits of vitamin D are well-documented (GreenMedInfo.com has identified over 200 health conditions that may benefit from optimizing vitamin D levels: Vitamin D Health Benefits page, and Henry Lahore's Vitamin D Wiki has far more), the therapeutic properties of sunlight are only now being explored in greater depth by the research community.
Below are detailed five noteworthy properties of sunlight exposure:
1) Sunlight Has Pain-Killing (Analgesic) Properties: A 2005 study published in the journal Psychosomatic Medicine titled, "The effect of sunlight on postoperative analgesic medication use: a prospective study of patients undergoing spinal surgery," analyzed patients staying on the bright side of the hospital unit who were exposed to 46% higher-intensity sunlight on average. The patients exposed to an increased intensity of sunlight experienced less perceived stress, marginally less, took 22% less analgesic medication per hour, and had 21% less pain medication costs. [i]
2) Sunlight Burns Fat...
