Ditch the Dust Ruffle
Unless you’re committed to washing it regularly (and who is?), a dust ruffle tends to collect, well, dust. And bedroom dust is made of little bits of sloughed-off skin (delightful), so it’s a magnet for allergy-causing dust mites. The resulting congestion could keep you from getting a good night’s sleep.
Also, introduce new pillows frequently, says Atul N. Shah, M.D., the medical director of the Center for Asthma & Allergy, in Shirley, New York. Research has found that a pillow can double its weight in three years due to (brace yourself) dust from you, plus dust mites and their, um, dust. “Many pillows can’t be easily washed, so they should be changed every 12 to 14 months. People with dust-mite allergies need to replace their pillows as often as every six months,” says Shah. (If you’re bothered by persistent sniffles or itchy eyes, it’s worth checking with your doctor to see if you’re allergic.) A cheaper idea: Use pillow covers, and wash them in hot water once a week.
