Vitamin D: Getting extra sun in August and September could help prevent flu

NEWS

A new scientific paper from the United States suggests that getting more rays of sunlight – and therefore vitamin D – could help prevent flu.

COMMENT

Sun exposure has traditionally been the main contributor to vitamin D status in humans. When sunlight reaches the skin, vitamin D is produced in the body naturally. But with government health authorities strongly recommending avoiding exposure to the sun over the past 40 years, research suggests overuse of sunscreen may have caused a dramatic increase in the number of people with deficient or insufficient levels of this essential micronutrient.

Significantly, therefore, there is also evidence of an inverse relationship between sun exposure and all-cause mortality. In a scientific review recently published in the International Journal of Cancer Research and Treatment (IJCRT), researchers note that women with active sun exposure habits have been estimated to have a 1- to 2-year longer life-expectancy. With such findings clearly contrary to the sun-avoidance advice currently promoted by government health authorities, the review concludes that the introduction of sensible sun exposure recommendations might improve public health.
