Three Simple Steps to Sun Safety

The incidence of skin cancer in the U.S. has doubled over the past decade. This is due largely to increased exposure to ultraviolet light outdoors and in tanning booths.

"Going into a tanning booth is like smoking - you may not get skin cancer but you're certainly going to cause premature skin aging, and you certainly are increasing your risk of getting skin cancer."

That's Dr. James Grichnik, a dermatologist at Duke University Medical Center. He recommends a three-step program to help prevent skin damage from UV rays.

First, since 75 percent of UV radiation hits the earth within two hours on either side of noon, schedule indoor activities during the middle of the day. This can significantly reduce the amount of UV light we receive.

Second, clothing reflects light away and is easier to put on than sunscreens, so it makes sense to cover up outdoors.

"People in the desert don't tend to go around in swimming trunks or bikinis. They know better; they know to cover up."

Third, use sunscreens with a minimum SPF of 15, preferably 30 or higher. Grichnik recommends those containing zinc oxide or titanium dioxide, since they reflect light away.
