This is one of those questions that lets you gauge how gross someone is in general. When was the last time you washed your PILLOWCASES?
They absorb a lot of dirt, oil, and dead skin. So you're supposed to do it every week or two at most. But a lot of us aren't hitting that mark.

Around 1 in 3 people admit they go longer than that . . . including 2% of Americans who say they've NEVER washed their pillowcases.
Most people don't go more than a month. That includes 35% who said they wash them at least once a week.
But women wash their pillowcases more often than guys do. And people under 25 are the most likely to be sleeping on pillowcases that have never been washed.
