Do You Know What You’re Sleeping With?

An article on interviewed Philip M. Tierno Jr., director of clinical microbiology and immunology at New York University’s Langone Medical Center, regarding what’s hiding in people’s sheets. Here are some important points:


  • Sheets and pillowcases should be changed once a week. Most Americans don’t change them for up to three weeks, a month or even more.
  • Human skin cells are meals for dust mites. Mites accumulate, along with their feces, in bedding.  Other things that can be found in bedding:
    • Animal hair, dander, fungal mold, fungal spores, bodily secretions, bacteria, dust, lint, fibers, particulates, insect parts, pollen, soil, sand and cosmetics
  • Debris in bedding can lead to respiratory issues, such as infections, or trigger allergies and/or asthma.
  • Wash bedding in water 130 to 150 degrees Fahrenheit and dry them on high. Bleach and non-bleach bleaches are germicidal and will eliminate the vegetative materials.
  • Protect your mattress – Without an impervious cover, your mattress is a “zoological and botanical garden,” Tierno said.
