More than two years ago I read of ongoing research by Dr. Pelle Lindqvist—reasearch indicating that greater exposure to sunlight resulted in longer life. I made several attempts to contact Dr. Lindqvist, but was unsuccessful. However, one of his colleagues answered my query and informed me that the research would not be completed later on and then be published. The results are now available, and they are impressive.
During a 20-year period, the subjects in the study who avoided sun exposure were twice as likely to die of any cause compared to those who had the highest sun exposure, and the researchers made this statement: “In both models the summary sun exposure variables showed a ‘dose-dependent’ inverse relation between sun exposure and all-cause death.”
The research also showed that women with “normal” sun exposure habits were not at significantly increased risk of either melanoma or melanoma-related death. The publication seemed to give vitamin D most of the credit for increased life spans among those who had high sun exposures, but also mentioned the possibility that nitric oxide production by sun-exposed skin may have been a factor. Regrettably, no mention of endorphins or serotonin was made.
Although I was thrilled with the results of the research, the research report itself had a problem: a statement that “ultraviolet (UV) radiation from the sun is known to heighten the risk of developing malignant melanoma (MM) of the skin. This condition is primarily responsible for increased mortality due to UV radiation exposure.”
No such risk is proven, and as I have so often stated in my blogs, sunlight exposure has profoundly decreased as melanoma has exponentially increased. It is counterintuitive to suggest that regular, moderate sun exposure causes melanoma. The figures the authors of the aforementioned research even stated that fact as a result of their research (see above).
So embrace the sunlight to increase both the quantity and quality of life!
