Allergy symptoms, such as sneezing and sniffling, can prevent you from having a good night’s sleep. To rid your bedroom of allergens, the National Sleep Foundation suggests the following: if you’re allergic to pets, keep them out of the bedroom and bathe them weekly; cover your mattress and pillows with dust mite covers; wash sheets regularly in hot water; use blankets made of synthetic materials, not wool; limit mold by keeping windows open in the bathroom, fix leaks and clean up water promptly; skip candles, scented laundry detergent, air fresheners, and other heavy fragrances in your bedroom; and clean furnace, air conditioner, and vacuum filters regularly. —National Sleep Foundation, July 2017
