Let’s talk about something that probably crossed your mind on a lazy day when you’re chilling by the window: Can you actually get sunburned through a window? I mean, you’re inside the house, right? The sun should NOT be your problem! But like…is it?
I know it sounds like something straight out of a bad movie plot; like, imagine casually lounging in front of your window with your iced coffee, scrolling TikToks, and BAM! Sunburn? Through the glass? Hmm, let’s get into it.
Okay, so short answer: YES, you can get sunburned through a window; but it depends on the type of window. (Let’s put down the iced coffee for a second.) Stick with me, because I’m spilling the tea on how much harm that sneaky sunlight can do to your skin, even when you’re indoors.
Let’s Talk UV Rays, Baby!
Let’s start with the basics: sunlight has two types of ultraviolet rays; UVA and UVB. Both are super important in this chat because they’re the reason tanning beds exist … and also why skin cancer exists too! Oops.
UVA Rays:
UVA rays are the more chill, long-wave UV rays you probably haven’t given much thought to. They’re the sneaky creepers. Why? Because they penetrate deeper into your skin and are primarily responsible for; you guessed it; aging. Yup, this is where some of those fine lines and wrinkles come from. Now, most windows actually let UVA rays through, meaning, if you’re vibing by the window too long, you might end up with premature aging (thanks but no thanks).
UVB Rays:
Okay, UVB rays are the real divas of the lineup. They’re short-wave rays and are the actual cause of sunburns. The good news is, most glass windows block UVB rays. So, that painful, lobster-red sunburn you get at the beach? That’s less likely to happen when you’re indoors. But don’t celebrate just yet…UVA wants some camera time.
If you’re thinking, ‘Oh, sweet, no sunburn!’ Remember: UVA is plotting against you by *aging* your skin.
So, yeah! You might not look like a tomato, but you could still end up with fine lines, uneven skin tone, and all that not-so-glam stuff.
Do ALL Windows Let UVA In?
Not all windows are created equal, babe! Let’s break down a few types of windows and how they deal (or don’t deal) with sunlight.
Regular Home/Car Windows:
Your average window at home (or in your car) lets in about 74% of UVA rays. If you’re sitting right next to your car window during a road trip or constantly getting that window sunlight while you’re binging Netflix in your room, consider this your sign to MOVE. Think about it: You’re basically slow-cooking your face with UVA rays. Yikes.
Tinted Windows:
Now, if you’re fancy like that and have tinted windows (hello, celebs, I see you), you’re in luck. Tinted glass usually does a waaaay better job of blocking UVA rays. Some blocks about 60% to 80%, which is pretty good! That said, most of us probably aren’t chilling in limos all day, so keep your skin protection game strong, tinted windows or not. (Don’t count on tinted windows as your sunscreen, k?)
Windows with UV Protection Coatings:
Good news for those who’re living in high-tech homes. If your windows come with a special UV protective coating or if you invested in some UV-filtering window film, please give yourself a gold star because you’re protected; like, up to 99% protection from UVA and UVB rays depending on the product. This is basically like having sunscreen built into your house. ICONIC.
What About Airplane Windows?
Omg, let’s NOT forget about airplanes! I mean, flying is cool, and that view from 30,000 feet? Chef’s kiss. But girl, did you know those airplane windows don’t play? They let in an even higher level of UVA rays than regular windows, especially if you’re right next to a window seat. High altitudes + the sun’s rays = MAJOR exposure.
Pro tip: If you’re on a long flight and scored the window seat (lucky you, but also maybe unlucky?), you need to lather up, babe. Sunscreen is your best friend up there, or at least pull down the shade and protect your skin.
Skincare Tips for Indoors
Okay, so what now? You probably thought UV protection was an outdoor-only deal. Me too, friend, me too. But since UWU (Unseen Window UV just made that up) is a thing, let’s talk about protecting our skin while withstanding indoor sun dangers too.
Sunscreen, Sunscreen, Sunscreen!
I know you’re expecting this tip because I say it all the time, but nothing beats sunscreen! When you’re near a window during the day, even at home, use a broad-spectrum sunscreen of at least SPF 30. You’re now officially an indoor sunscreen queen.
Sunglasses, You Say?
Did you know your eyes can get sun-damaged too? I know this isn’t a sunglasses commercial, but you’re going to want to wear some shades if you’re near windows a lot. Your eyes and the skin around them are SUPER delicate (hence why we have all those luxurious eye creams), so protect them!
Use Some Curtains or Window Films
Low-key obsessed with curtains right now because, hello, they block out light and protect your skin. Plus, they come in cute aesthetics; so you get to protect your living room vibe and your skin at the same time. Two words: Window. Films. If you’re really serious about blocking UVA rays, UV-specific window films can work wonders; think of them like sunscreen for your windows.
| UV Ray Protection Options | UVA Block | UVB Block |
|---|---|---|
| Regular Window Glass | 70%-75% UVA let in | Blocks most UVB |
| Tinted Glass / Car Windows | 20%-40% UVA let in | Blocks UVB |
| UV-Coated/Window Film Glass | Up to 99% UVA blocked | Blocks UVB |
Pro tip: Reflective window films will also keep things cooler in the summer, so your energy bill isn’t giving you heart palpitations 💸.
Wait. Does This Mean You Need Sunscreen Indoors!?
Short answer: yes! But hear me out before you decide I’m too high-maintenance for telling you to chill with SPF in your own house.
If your day consists of Netflix, TikTok, and gorging on iced lattes while sitting 3 feet away from a sun-drenched window all day… then yeah, sis, slap on some sunscreen. Especially if you want to keep your skin plump and dewy and avoid pesky dark spots or early aging!
For those of you who work in dark rooms and never go near windows? Well, you can skip sunscreen IF you don’t end up facing the sun for more than a few minutes in a day. (But TBH, I still use sunscreen ’cause I’m extra like that.)
OMG, What If I Slept by the Window Last Night?
Okay, keep calm and don’t panic! If you were sleeping right by a window and forgot to block the sun, it’s not the end of the world. Just check your skin today. If you didn’t get sunburned, congrats! But if you’re regularly getting a ton of window sunlight while you nap or sleep, maybe try moving your bed; unless you want to end up looking like a sun-expired potato in your 30s 😬.
At the end of the day, a few UV rays can sneak in even when you’re just stuck in traffic or watching the sun set magically from your couch. Bottom line: UV damage is a long game, babe. Maybe you won’t turn into a raccoon overnight, but you should STILL be vigilant about your skincare.
Quick Recap For The Road:
- UVA rays pass through glass windows and can age your skin faster (hello, wrinkles).
- UVB rays usually don’t sneak past regular windows. So, you’re unlikely to get full-blown sunburn indoors.
- Tint/UV films on windows? BIG PLUS, highly recommend.
- SPF 30 or higher inside and outside is the BFF you didn’t know you needed.
- Consider curtains, shades, or window films IF you’re sunbathing next to that glass every day.
And that’s the tea, babes. You can 100% get sneaky sun damage through windows, so keep rockin’ that SPF daily; even when you think you’re just staying in for a lazy day of skincare masks and “Bridgerton” marathon sessions (been there, babe). You owe your future self that much! 😘
