How Is Human Sun Exposure Related To Cancer And How Can It Help Cure/Prevent It

For 40 years we’ve been warned about the dangers of over-exposure to sunlight and ultraviolet (UV) radiation, which causes Melanoma[1], a life-threatening skin cancer. Contrary to this position, there is growing evidence that indicates a lack of sun exposure, and the subsequent low vitamin D levels that are associated with it, can cause chronic conditions and cancer. Recent studies show that vitamin D deficiency can lead to a 30%-50% increase in the risk of developing breast, ovarian and prostate cancer. 

Studies have shown that sun exposure, at levels that aren’t strong enough to cause melanoma skin cancers, could reduce the risk of developing malignant tumors. More recently, the analysis estimates that a staggering 50,000 and 63,000 Americans die prematurely from cancer every year due to not getting enough sunlight. This is particularly important as sun exposure is dependent on geographical latitude. Epidemiologic research[in the 1980’s & 1990’s found a negative correlation between sun exposure, latitude, and cancer.  For instance, people who lived at lower latitudes were less likely to die from cancer than adults living at a higher latitude as they were exposed to more sunlight. The implication is that low level regular exposure to the sun is vitally important to our health.  Vitamin D has unique properties in slowing or preventing cancer at a cellular level[. To help prevent against cancers, getting enough safe sun exposure should be a key component of all healthy living plans.
