Here’s the sneaky side-effect of water: it makes you feel cool and refreshed, which tricks your brain into thinking you’re not burning. You’re floating, the breeze is nice, and your skin feels fine. But that’s a lie—your skin is microwaving like a silent popcorn bag. A study by Environmental Health Perspectives showed that people who swim or surf are three times more likely to get sunburned than those who stay on the beach, simply because they don’t feel the heat.

Plus, water washes off sunscreen. If you’re not using a water-resistant formula (and reapplying every 80 minutes), you’re basically wearing a lie. So, that “water-safe” feeling? It’s a trap. Don’t fall for it.
But What About Deep, Murky Water?
You might be thinking: “Well, what if I’m in a cloudy, muddy lake? Surely that blocks more, right?” Sort of. Murky water (with lots of particles or algae) does block more UVB because the stuff floating around absorbs the light. But guess what? UVA rays still cut through like a hot knife through butter. And UVA is the main culprit for skin aging and wrinkles. So, that murky pond might save you from a burn, but it won’t save you from crow’s feet.
And here’s a fun fact from the National Oceanic and Atmospheric Administration: in the ocean, UV can penetrate up to 20 meters (65 feet) in clear water. That’s deeper than most recreational dives. Even fish get sunburned—no, seriously, salmon and tuna have been documented with UV-induced skin lesions. If fish can get cooked, so can you.
