You've probably seen this tip floating around, and honestly? There's some truth to it, but it's not quite the miracle cure it sounds like. What's really happening: UV rays from sunlight do have antibacterial properties and can kill some surface germs. Plus, fresh air and sunshine naturally deodorize fabrics—which is why your bedding smells so good after hanging outside. The catch: UV light only works on the surface. Those dust mites living deep inside your pillow? They're still there, cozy as ever. Same goes for bacteria and allergens buried in the filling. Here's what actually works: Wash your pillowcases every week (seriously, this is the one that matters most for your skin). Wash the actual pillows every few months. Use pillow protectors—they're game-changers. Air everything out regularly, sunshine or not. Replace pillows when they're lumpy or old (usually every 1-2 years). Bottom line: Sunning your pillows is a nice refresh and costs nothing, so go for it! Just don't skip the actual washing. Your face spends 6-8 hours on that pillowcase every night—keep it clean and you'll notice the difference in your skin. Think of it like this: sunlight is a bonus, not a replacement.
