New research reveals the growing obsession with protecting ourselves from the sun may have come at a serious cost to our health.
There is increasing evidence that overuse of sunscreen has caused a dramatic rise in the number of people with deficient or insufficient levels of vitamin D, a nutrient produced naturally in the body when skin is exposed to sunlight. This is due to the application of high-factor sunscreen essentially nullifying the body’s ability to produce vitamin D. Around 1 billion people worldwide are now believed to have low levels of this essential nutrient.
Interestingly, therefore, there is also growing evidence of an inverse relationship between sun exposure and all-cause mortality. A scientific review published in the International Journal of Cancer Research and Treatment in 2018 noted that women with active sun exposure habits are estimated to have a 1- to 2-year longer life-expectancy. With such findings clearly being contrary to the sun avoidance advice currently promoted by government health authorities, the review concluded that the introduction of sensible sun exposure recommendations might improve public health.
