How Often (And How) to Wash Your Sheets

 
There’s nothing better than hopping into a freshly made bed at the end of a long day. Unfortunately, the remnants of the day — sweat, dirt, crumbs from your lunch — get in with you, too.
 
So how often should you really wash your sheets?
 
The answer is that washing your sheets about once a week will set you up for a healthy night of zzz’s. You can rest easy knowing you’re in a clean environment — even if your laundry pile is a mile high.
 
Not ready for laundry day? Rotating through at least three sets means you’ll never have to wait to freshen up. No one likes a sheet that looks like swiss cheese, so we recommend replacing them every one to five years.
 
Casper’s Take: If you’re sticking to making your bed on a weekly basis, make it easy for yourself.
 
Double-up on fitted sheets so there’s one less thing to wrangle next week. We’re biased towards the Casper sheets because they feature smart details like grippy fabric, which cuts down the time it takes to make the bed.

If you spill coffee or eat a crumbly cookie in bed, it’s easy to see that your bedding needs a wash. But it’s the things you can’t see, like dust mites, that you should be worried about.
 
Your body temperature drops a couple of degrees as you get cozy in bed. Heat moves out of your limbs into the surrounding environment and makes you feel overheated (especially if you are sleeping with others).
 
As a result, you sweat. Long after you’ve gotten up, the sweat stays and invites allergens, weird stuff like dust mites, and other things into your mattress.
