THEY’RE MOCKING GWYNETH PALTROW ON SUN EXPOSURE, but the fact is, Paltrow is right. People evolved to need sun, and the consequences of too much sun, it’s becoming clear, are likely to be less serious than the chances of not enough. Too much sun gives you wrinkles and an elevated chance of skin cancer — but skin cancer is easy to diagnose and usually easy to treat if it’s caught early. Too little sun increases your risk of ovarian, colon and other cancers that are much harder to spot, and often more serious. Plus, diabetes.
