You know, I used to think that sitting by the window with a sunny view was like a safe sunbathing session, but it turns out it’s not quite that simple. There’s this funny thing where windows can block some UV rays but not all, which might leave you feeling a little toasty even when you’re inside. Did you know that UV radiation can sneak through glass, just enough to make your skin say, “Hello, tan lines!”? So, while your window might be doing its best to keep the sun’s rays at bay, it’s not a perfect shield. Just a little heads-up: if you’re basking in that lovely sunlight, you might still want to slather on some sunscreen or close those blinds if you’re feeling a bit too warm.
