Keeping Dust Mites Out of Your Bed.
If you wake up sneezing and sniffling, you may have dust mites in your bed. The National Sleep Foundation recommends the following to prevent dust mites: run a dehumidifier in your bedroom, as dust mites thrive in humid conditions; buy dust-proof covers for your pillows and mattress; wash bedding in very hot water and dry it in the hot cycle every week; and dust and vacuum your bedroom weekly.
