A US doctor has claimed warnings about getting skin cancer from the sun may have done more harm than good.
Dr Michael Holick says we are missing out on essential vitamin D by staying out of the sun - and that causes thousands of deaths each year.
However, his controversial views have cost him his job as Professor of Dermatology at the Boston University School of Medicine.

Dr Holick told the BBC Today programme: "What I am suggesting is sensible sun exposure. We are talking probably about no more than maybe three to five minutes to your hands, face and arms two to three times a week.
"People don't realise that 90% - 95% of your vitamin D requirement comes from exposure from sunlight, and if you always wear sun block and never have direct sun exposure you will become vitamin D deficient, and at high risk of developing many serious chronic diseases."

The man was professor of dermatology, i think its fair to assume he knows what he's talking about. And three to five minutes, two or three times a week is hardly recommending you spend two hours in the midday sun every day.
