Nursing's Shanina Knighton on how often we should wash our sheets and pillows

This is how often (and the exact temp) you need to wash your bed sheets and pillowcases this summer, according to an infection prevention expert

Tom's Guide: Shanina Knighton, research associate professor at Frances Payne Bolton School of Nursing, explained how often we should wash our sheets and pillows during the summer. "Wash your sheets and pillowcases at least once a week; but those with skin conditions, an active lifestyle, or allergies will need to change them more frequently," said Knighton.
