Sun exposure through glass is dangerous

Think you’re safe from sun damage when you’re hiding indoors?

Think again. Those pesky UV rays can get you even when you’re sitting near a window or driving a car. Well, some of them can…

Can You Get A Sunburn Indoors?

“But, wait, Gio. I’ve never gotten a sunburn indoors. Are you sure UV rays can get me inside?”

Here’s the deal: UVB rays cause sunburns. If you’re behind a window, you’re safe from them. UVB can’t penetrate through glass. Phew!

But, that doesn’t mean you’re safe from all UV rays…

Why You Need To Wear Sunscreen Indoors

UVB may not be able to penetrate through glass, but UVA rays sure can.

The A in UVA is for aging. These rays are responsible for premature wrinkles and dark spots.

The worst part? They don’t even make your entire face age at the same rate! If you look at the face of someone who’s been driving cars or vans for a living for years, you’ll noticed that one side of his face – the side nearest to the car windows – has twice as many wrinkles and dark spots!

Want to know something even scarier? UVA rays also increase your risk of skin cancer. Don’t take any chances!

How Can You Prevent Sun Damage Indoors?

I’m not suggesting you stop sitting near windows or never get into a car again. Geez, where’s the fun in that?

But, before you do it, you should take a couple of steps to protect yourself:

  1. Wear sunscreen: All day, every day, even when you’re staying indoors. Make sure it is broad spectrum. Not all sunscreen protect from UVA rays – and they’re the ones getting indoors! Click here to find out which UV filters protect from UVA rays. (P.S. You can’t go wrong with Zinc Oxide).
  2. Window tinting: Applying a protective UV film to your windows reduces UVA penetration by about 15-30%.
