Are you safe from the sun when indoors?

SPF and wide-brimmed hats can protect your skin when you’re outside having fun in the sun. But did you know damaging UV rays can still reach you indoors? 

Both UVA and UVB rays – the two main types of ultraviolet light – can age your skin and lead to skin cancer. UVB rays are shorter and stronger, causing sunburn and directly altering your DNA. This high-energy light is typically absorbed by window glass, so it affects you less when you’re inside. 

“UVA rays are the culprit when it comes to indoor UV exposure,” says Dr. Linda Serrano, a dermatologist at Aurora Health Care. “They’re longer and less intense, but they can pass through windows and penetrate your skin more deeply than UVB.” 

UVA rays also make up the majority of UV light, which makes it even more important to consider your UV exposure when inside. Here’s how you can maximize indoor sun safety: 

• Stay out of direct sunlight, and watch out for sneaky early morning and late afternoon sunlight when the sun is low in the sky. 
• If you hesitate to hang curtains or blinds, apply UV-blocking window film that won’t obstruct your view. 
• Choose a broad-spectrum sunscreen to protect against both UVA and UVB rays. Apply sunscreen to exposed skin like your face, neck, hands and arms – even on cloudy days. 

Another overlooked way UV rays are reaching your skin? Your car.  

Many car windshields are manufactured with a layer of UVA-blocking film, but passenger windows may not have it. Consider having your windows tinted with UV-minimizing film, especially if you drive for work or have a lengthy commute. Make sure to utilize your sun visor and wear sunglasses, too. 

“No matter where you’re getting UV exposure, it’s important to protect your skin,” Dr. Serrano says. “Aside from preventing wrinkles and other signs of aging, taking preventive measures decreases your risk of skin cancer, too.”
