…2. A large epidemiological study found women with higher solar UVB exposure had only half the incidence of breast cancer as those with lower solar exposure and that men with higher residential solar exposure had only half the incidence of fatal prostate cancer.
Note: a 50% reduction in either of these cancers greatly exceeds what any of the approaches we use to treat or prevent them have accomplished.
3. A 20 year prospective study evaluated 29,518 women in Southern Sweden where average women from each age bracket with no significant health issues were randomly selected, essentially making it one of the best possible epidemiologic studies that could be done. It found that women who were sun avoidant compared to those who had regular exposure to sunlight were:•Overall 60% more likely to die, being roughly 50% more likely to die than the moderate exposure group and roughly 130% more likely to die than the group with high sun exposure.
Note: to be clear, there are very few interventions in medicine that do anything close to this.
•The largest gain was seen in the risk of dying from heart disease, while the second gain was seen in the risk of all causes of death besides heart disease and cancer (“other”), and the third largest gain was seen in deaths from cancer.
Note: the investigators concluded the smaller benefit in reduced cancer deaths was in part an artifact of the subjects living longer and hence succumbing to a type of cancer that would have only affected them later in life.
• The largest benefit was seen in smokers, to the point non-smokers who avoided the sun had the same risk of dying as smokers who got sunlight.
Note: I believe this and the cardiovascular benefits are in large part due to sunlight catalyzing the synthesis of nitric oxide (which is essential for healthy blood vessels) and sulfates (which coat cells like the endothelium) and in conjunction with infrared (or sunlight) are what create the liquid crystalline water that is essential for the protection and function of the cardiovascular system).
So given all of this, I would say that you need a really good justification to avoid sun exposure.
This is an excerpt from the article Dermatology’s Disastrous War Against The Sun. I chose this section because the study is large, well-conducted and convincing. Ofc, the whole article is well-worth reading. ABN
