Sunlight is well-known to provide us vitamin D, but did you know that it kills pain, keeps us alert at night, burns fat and more…

Our biological connection and dependence to 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 journalPsychosomatic 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: A 2011 study published in The Journal of Investigative Dermatologyrevealed a remarkable fact of metabolism: The exposure of human skin to UV light results in increased subcutaneous fat metabolism. While subcutaneous fat, unlike visceral fat, is not considered a risk factor for cardiovascular disease, it is known that a deficiency of one of sunlight’s best known beneficial byproducts, vitamin D, is associated with greater visceral fat.[ii] Also, there is a solid body of research showing that vitamin D deficiency is linked to obesity, with 9 such studies on our obesity research page
