Get back in the sunshine!

Too little sun causes harm, cancer specialists say.


Cancer specialists around the world are rethinking their advice to cover up in the sun amid growing concern that staying in the shade may be causing harm.

Australia is revising its warnings about the risks of sun exposure because of fears about vitamin D deficiency, which increases the risk of a range of diseases from cancer to osteoporosis, in what doctors have described as a "revolution".

Bruce Armstrong, professor of public health at Sydney University, said: "It is a revolution. I have worked in public health and been preaching sun avoidance for 25 years. But this statement says that there are two sides to the story."


What is astonishing is that the experts should be so surprised. Once again it looks as though we would have done better to have ignored their advice - as most of us have.
