You do not need to do all of the things listed. If you smoke, ask your doctor for ways to help you quit. Ask family members to quit smoking, too. Do not allow smoking in your home or around you. Be sure no one smokes at a child's day care center.
Dust mites Many people with asthma are allergic to dust mites.
Water must be hotter than 130 F to kill the mites. Wash the sheets and blankets on your bed each week in hot water. Dehumidifiers or central air conditioners can do this. Try not to sleep or lie on cloth-covered cushions or furniture. Remove carpets from your bedroom and those laid on concrete, if you can.
