Clean your bedroom regularly
Remove mites and associated debris from your bedroom with a HEPA-filtered vacuum. If your vacuum doesn't have a HEPA filter, AAFA recommends obtaining one from an allergy supply store.
Wash your bedding in hot water weekly
Make sure water is 130°F to kill dust mites. Finish drying in a hot dryer.
Invest in dust-proof mattress and pillow protectors
These densely woven zipped coverings keep dust mites out of beds. The AAFA says bedding and housewares businesses sell them.
Invest in a humidifier
Cold air is drier and worse for severe asthmatics. Bose suggests using a humidifier in your bedroom in winter, depending on where you reside.
Don’t sleep with pets
If you have dogs, keep them out of the bedroom to prevent dander from sticking to the carpeting and bedding, suggests Bose.
Keep your head up
Bose says sleeping flat can worsen postnasal drip and asthma attacks in people with colds or sinus infections.
Get tested for sleep apnea
According to the American Thoracic Society, asthmatics may develop sleep apnea. Sleep apnea causes frequent breathing pauses.
