On this eve of change to winter time, exposure to the sun’s rays is no longer entirely relevant. Except for researchers from the universities of Edinburgh and Southampton (Great Britain) who have just published in the medical journal Diabetes, a study on UV exposure and the functioning of the metabolism. And the good news is that the more we expose ourselves to UV rays, the more we boost our metabolism and the more we delay the onset. type 2 diabetes.
In the sun, the skin releases a substance that changes our metabolism
Facts that the researchers, led by Dr Richard Weller, professor of dermatology at the University of Edinburgh, observed on mice. With the help of researchers at the Children’s Institute in Perth, Australia, they exposed overfed mice to UV light. They then found that it slowed their weight gain and that the mice had fewer warning signs of type 2 diabetes.
“The beneficial effects of UV treatment are linked to nitric oxide, which is released by the skin after exposure to sunlight,” explains the doctor. This substance plays a role in the way we digest and process food and sugar, and appears to ward off certain bad metabolic conditions like diabetes.
“Studies like this help us understand that the sun can be good for us too. We must indeed remember that skin cancer is not the only disease that can kill us but that type 2 diabetes can do it just as sneakily. So we should review our advice on sun exposure, ”the doctor said.
