Many people just don't wash their sheets often enough. A 2017 survey found that only 44 percent of the 1,000 Americans surveyed wash their sheets once or twice a month. Just 11 percent get around to it around once a season and 5 percent decrust their sheets only once or twice a year.
So just how often should you wash your sheets? Well, it depends on the circumstances.
Our experts say you should wash your sheets -- and other bedding -- at least once every two weeks. If you have night sweats, or just sweat a lot in general, bump washing up to once a week.
If you're allergic to dust mites, the Asthma and Allergy Foundation of America recommends washing your bedding at least once a week. You'll need to wash them in water that is at least 130 degrees Fahrenheit (54.4 Celsius) to kill the dust mites.
Now, if you're sick with something contagious, the rules change. Sheets and other bedding need to be changed as soon as you feel better to prevent contracting the illness again. The water will need to be between 140 and 150 degrees Fahrenheit (60 to 65.5 Celsius) to kill the germs, so select the sanitize option on your washer. If your washer doesn't have a sanitize option, use the highest heat setting on your dryer.
