Michael Breus, PhD Sleep Specialist: How often should I change my sheets?
If you're wearing pajamas, changing sheets once a week is fine.
If's just if you're not wearing pajamas or sleeping in the nude that you'd probably want to be changing them at least twice a week.
Also, by the way, a lot of people when they change their sheets, they don't wash their mattress pad, and so that's another thing that people need to do.
You need to have a couple of mattress pads that you can be again rotating in and out and changing more often.
Narrator: And change those every week too?
Michael Breus, PhD Sleep Specialist: I would.
