How Often Should You Change Your Pillowcase?

How often a pillowcase should be changed sparks much consideration concerning health, beauty, and comfort. While many people appreciate the fresh feel and smell of a clean pillowcase, some may miss the advantage of proper and timely pillowcase laundering to overall skin appearance and general well-being. We reviewed biologist, dermatologist, and governmental health documentation to help determine pillowcase cleanliness best practices.

You should change your pillowcase regularly. General guidelines suggest:

  • Every few days for normal use.
  • Every day if you have skin, allergies, asthma, or other health issues.
  • A maximum of seven days.

How often should you change pillowcases?

Pillowcases accumulate dirt, oil, saliva, and sweat. Daily use causes bacteria collection and possible allergic reactions. Pillowcases should be changed regularly and washed separately from pillows.

While sheets may be washed weekly, pillowcases should be changed and washed every few days to remove accumulated bacteria. If you have skin issues, allergies, asthma, or other health problems, you may want to change your pillowcase daily.  The more frequent changes will facilitate healthier skin and help avoid oil and bacteria exposure. While you can flip a pillow over to extend the use a few more days, you should use a pillowcase no more than a week between laundering.

Pillowcase Bacteria

While a regular blacklight may not allow you to see bacteria because of the small size of the bacteria, the ultraviolet (UVA) light may show bacteria-containing biological fluids. In total darkness, biological fluids, such as saliva, fluoresce (radiate visible light). A blacklight causes these materials to glow and may provide insight into the need for frequent pillowcase changing.

If you are not yet convinced, consider the possible bacteria in your pillowcase compared to other areas of the home. Members of a North Carolina State University biology department team asked participants to collect culture swab samples from nine home locations, including a cutting board, an exterior door handle, a toilet seat, and a pillowcase. According to the Wildlife Our Homes project report, the toilet seats and pillowcases tested had similar bacteria levels.
