💡 Trivia Sunburn Can Still Happen on a Cloudy Day

[Beatriz9]

Clouds can reduce ultraviolet radiation, but they don't necessarily block all of it. Significant amounts of UV can still reach the ground through or around cloud cover. Under certain cloud conditions, scattered radiation can even complicate how much UV reaches the surface.

That's why someone can spend hours outside without feeling strong sunshine and still develop sunburn. Temperature isn't a reliable measure of UV exposure either. A cool, cloudy day doesn't automatically mean the Sun can't affect the skin.

True! We often think that if it’s cloudy or not too hot, we’re safe from the sun, but UV rays can still reach us. It’s a good reminder that sun protection isn’t only for bright, sunny days. Even on cool and cloudy days, sunscreen and other protection can still make a difference.
