How sunshine could tackle obesity

Friday October 24th, 2014

Plenty of sunshine may help to combat obesity and the risk of developing diabetes, according to a new study.

Sunshine is normally linked to vitamin D but in the latest study researchers say another chemical process is responsible.

The research involved laboratory mice and the researchers say they may not apply to humans.

The study involved researchers from Perth, Australia, together with teams at the universities of Edinburgh and Southampton, UK.

According to the study, ultraviolet light from the sun leads to the release of the chemical nitric oxide. In the study, the mice were over-fed but those exposed to light put on weight more slowly than others - and showed fewer of the early warning signs of developing diabetes.

The researchers cite other research suggesting that ultraviolet light can help humans manage blood pressure.

The findings are reported in the journal Diabetes.

Researcher Dr Richard Weller, a dermatologist in Edinburgh, said: "We know from epidemiology studies that sun-seekers live longer than those who spend their lives in the shade. Studies such as this one are helping us to understand how the sun can be good for us.

"We need to remember that skin cancer is not the only disease that can kill us and should perhaps balance our advice on sun exposure."

And Dr Shelley Gorman, from the Telethon Kids Institute, Perth, said: "Our findings are important as they suggest that casual skin exposure to sunlight, together with plenty of exercise and a healthy diet, may help prevent the development of obesity in children."
