A recent study on UVB rays has confirmed the notion that the higher you are, the quicker you fry. But just how fast we fleshy humans burn might surprise you. The research, which was conducted in Vail on a clear spring day, showed that a person of average complexion who’s not wearing sunscreen¿at 11,000 feet at noon¿can burn in just six minutes. Less time than it takes to cook linguini. “It’s vital that skiers recognize the increase in UV exposure at higher altitudes and take extra precautions to prevent sunburn and skin cancer,” says Darrell Rigel, M.D., the study’s lead author. Wear protective clothing, avoid the midday sun, and slather on the sunblock, he says.
