We all know it by now: the sun rays are dangerous and we should wear sunscreen every day to avoid premature aging, sunburn and cancer. But what about when we’re driving or just sitting next to a window? Is the sun exposure we’re getting that way all year round dangerous for our health and skin as well?
Sun exposure through glass doesn’t cause sunburn
You’ll be happy to know that you won’t run the risk of getting sunburned if you driving in your car or are anywhere near a window. That’s because sunburns are caused by UVB rays and these cannot penetrate through glass (unless the window is open, of course!). However, while this is good news, it doesn’t mean that sun exposure through glass is completely harmless. Quite the opposite actually.
Sun exposure through glass can cause premature aging and increase the risk of cancer
Driving in your car or sitting next to a window may not cause sunburn, but the sun exposure you’re getting that way is still dangerous. UVB rays may not be able to penetrate glass, but UVA rays will get through it and these not only increase the risk of developing skin cancer, but are also responsible for premature aging. And did you know that one side of your face is more at risk than the other? In fact, the side of your face that is nearest the car window or facing any window at your house/office is more exposed to the sun ray and can age more quickly than the rest of your face!
How to prevent damage caused by sun exposure through glass
There are a couple of ways to protect your skin from the damage inflicted to it by sun exposure through glass. One solution is window tinting: you can apply a protective UV film to your windows which will reduce UVA penetration to about 15-30%. However, there is one more simple solution and I’m sure you all know what that is. Yep, before getting in your car or sitting next to a window, always apply a good broad-spectrum sunscreen (or at least a moisturizer with SPF in winter) on all exposed areas of your body.
