You can do a lot while you sleep. Via

Go wash your sheets.

Your mother was right: it’s not just lazy, it’s also gross not to change your sheets.

Vice asked experts what goes on on unwashed sheets, and they painted a pretty horrible picture. Think mites are bad? Well they’re eating dead skin cells and pooping on your sheets, because you’re feeding them. All that semi-harmless bacteria on your skin is getting transferred, where it can reproduce and thrive and grow out of proportion.

Your pillow case that’s lined with lotion or sweat or makeup is grinding against your face every night, clogging your pores and returning all that excess dead skin and natural oil right back to your skin.

Go to bed with a paper cut, you could actually, really wake up with a staph infection.

Go wash your sheets.
