How Often Should You Wash Your Sheets?
Tuesday, 24 April 2012 | by Pat's Picks

An article in the Wall Street Journal this morning has got my itching to wash my sheets. Dr. Philip M. Tierno Jr. says most people don’t wash their sheets frequently enough. Dust mites apparently love to dine on human skin, which means your bed is full of them. And their feces. And also probably “dust, lint, fibers, particulates, insect parts, pollen, soil, sand and cosmetics.” Oh, and most people sweat about a quart of water a night. Tierno suggests washing sheets every week in 130- to 150-degree water.
