You Really, Really Need to Be Washing Your Sheets More Often

Or do you like sleeping in a ‘botanical park’ of bacteria?

Call us paranoid, but when we hear a phrase like “ideal fungal culture medium,” we listen up.

In a report about how bedding becomes contaminated over time, that phrase was used to describe what happens to bed sheets after they’re used — and sweated into — over time. Also, it happens a lot sooner than you might think.

To counteract the fungal breeding ground sweat, skin cells, soil, lint, pollen and other unwanted bedding guests can create and avoid sleeping in a “botanical park” of bacteria, NYU microbiologist Philip Tierno advises changing bedsheets once a week, Business Insider reported.

If you don’t, Tierno says the buildup can become “significant” and, in addition to being downright gross, has the potential to make you sick and experience allergy-like symptoms.

“If you touched dog poo in the street, you’d want to wash your hands,” Tierno told Business Insider. “Consider that analogous to your bedding. If you saw what was there — but of course you don’t see it — after a while you have to say to yourself, ‘Do I want to sleep in that?’”

Do you wanna sleep in Fido feces? If the answer is no, guess it’s time to go to the laundromat.
