To protect yourself, apply sunscreen to any exposed areas (like your hands, forearms, and face) before getting into your car, especially in the spring and summer months, says Anthony Mancini, M.D., head of pediatric dermatology at Children’s Memorial Hospital in Chicago. If you’re buying a new car, consider one with tinted windows, which keep out almost four times more UVA light than regular ones.
