This ties back to the glass question. Tanning beds use special bulbs that emit mostly UVA and a little UVB. They don’t use standard window glass. In fact, they’re designed to let both rays through.

So, don’t get any ideas about building a DIY tanning bed in your sunroom. Siting a regular lamp behind a window won’t turn you into a bronzed god; it’ll just make you look like a tired, wrinkle-prone person who smells like fried chicken.
The lesson? Glass is a filter, not a free pass. It lets through the dangerous, aging rays but blocks the ones that actually give you a lasting tan. It’s like ordering a gourmet meal and only getting the side of kale chips.
So, What’s the Verdict for Sarah?
I texted Sarah after my Cancún trip: “Did your cabana tan work?” She sent me a photo of her arm looking… exactly the same. She admitted she got a slight, temporary pink flush, but it faded in two hours. Zero tan.
Here’s the simple truth: You can get a tiny bit of color through glass, but it’s not a real tan. It’s more like a warning signal from your skin saying, “Hey, I’m being irradiated here!” Don’t confuse a little pigment with a healthy glow.
So next time you’re stuck in traffic or lounging by a sunny window, remember: sunscreen is still your best friend. Even inside. Because UVA rays don’t care about your “I’m just sitting here” excuse. They’re opportunistic little jerks. And your skin deserves better than a jerk.
P.S. – If you’re really desperate for a tan, just buy a bottle of self-tanner. It’s cheaper than a dermatologist appointment and won’t make you look like a human raisin at age 35. You’re welcome.
