Towels: They absorb more than just water

Whenever you use a washcloth, hand towel, or bath towel, skin cells slough off your body and stick to the fabric. Those cells serve as food for bacteria, Tierno says. Plus, bacteria thrive in the damp, densely woven material, which has lots of nooks and crannies for them to hide in. As you reuse towels, these bacteria can transfer back to you and cause skin infections. "If you have any kind of wound, you may be infecting yourself with whatever is on the towel," says Elizabeth Scott, Ph.D., co-director of the Simmons College center for hygiene and health.

Your cleanup: Scott suggests washing your bath towel at least weekly if you're the only person using it, and using fresh towels daily if you share. Anything that gets soaked—like a washcloth—should be washed after every use. And don't forget about guest towels; wash them every time you have visitors. Who knows where those people have been?

I kind of only care about towels and sheets and stuff like that, and I still wouldn't wash them that much. Not like I'm getting sick everyday either, but they make it sound kinda gross though.
