![]() We know that even one blister-causing burn in childhood or adolescence more than doubles your melanoma chances. It’s totally true that sunburn plays a clear and significant role in your chances of developing melanoma, the deadliest form of skin cancer. The left side, of course, is exposed to UV rays through the driver’s side window. ![]() And all of that on-the-road exposure adds up: In America, skin cancers are more common on the left side of the face and body, reports a study in the Journal of the American Academy of Dermatology. While all windows do a pretty fab job of shielding you from sunburn-causing UVB radiation and coated windshields block over 90% of UVA radiation, your car’s side windows offer about 25% less protection from UVA rays, according to a report in JAMA Ophthalmology. Car windows only offer so much protection You know what also does this? Sand and water. Why? The white stuff reflects up to 80% of the sun’s UV light, so that means that the sun’s cancer-causing and age-accelerating rays hit you twice. The snow increases UV exposureĪ sunny, snowy day is doubly dangerous for your skin. The Skin Cancer Foundation reports that wind can actually reduce your skin’s natural sun protection, allowing more of the sun’s UV rays to penetrate and damage the skin. Windburn? Are you sure? It turns out that chapped, red, wintery faces are likely sporting sunburns in disguise. In fact, light or thin clouds may even enhance UV levels because of the way clouds scatter the light, notes the World Health Organization. And that’s not cloudy summer days, mind you, but any cloudy day. The truth is, up to 80% of harmful UVB and UVA rays burn right through the clouds, according to the Skin Cancer Foundation. In short, exposure to the sun during the winter puts you at the very same risk as exposure during the summer, notes the Cleveland Clinic. (Mind blowing, right?) The burn of the summer’s sun is actually due to infrared radiation which, weirdly enough, does not cause sunburn. While we naturally associate summer’s heat with sunburn, damaging UV rays can’t actually be felt.
