Why You’re More Likely to Get Skin Cancer On the Left Side Of Your FaceYou do this every day
In the study, scientists found that front windshields blocked an average of 96 percent of UV rays—comparable to an SPF of 30.
Side windows, on the other hand, only blocked an average of 71 percent of UV rays. Some of the cars that were tested filtered out as little as 44 percent of the rays.
The more time you spend driving in your car, the greater your risk of cataracts and skin damage—including skin cancer—on your left side, says study author Brian Boxer Wachler, M.D., of the Boxer Wachler Vision Institute in Beverly Hills.
And if you live in a country where you drive on the left side of the road, you’re more likely to experience sun damage on your right side.
Dr. Zeichner says you may even be at risk if you’re running on a treadmill at the gym next to a big, sunny window, or if you sit in an office with major sun exposure.
Your move: Put sunscreen with an SPF of at least 30 on your face, ears, neck, arms, and scalp or hair part before you begin a long drive, Dr. Zeichner recommends. The same goes if you expect to be near sunny windows for a long period of time.
Also, close your sunroof or convertible hood between the peak sun hours of 10 a.m. to 2 p.m. to avoid a major, direct sun hit.
