Have allergies? Consider these habits part of your sleep hygiene routine.
All those books and knickknacks are dust magnets; move them to other rooms. Skip throw pillows, too; not only are they dust mite paradise, they're often tossed on the floor (getting even dustier).
Enforce a no-pet policy
Kicking Miss Snugglepaws out of your bed won't completely eliminate the amount of dander that makes its way into the bedroom, but it will help.
Vacuum—like, a lot
Carpets are killer for people with allergies. If you can't replace your carpets with washable area rugs, take a spin around the floor with your HEPA vacuum at least once a week.
Dry your hair before bed
Falling asleep with damp tresses can encourage mites and mold in your pillow. If you're not a fan of the blow-dryer, it may be worth bumping your bath or shower earlier.
