    Font Size

    It's important to take steps at home for asthma prevention if you have allergies.

If you can avoid coming in contact with the substance you are allergic to (allergen), you may be able to prevent symptoms of an asthma attack.

    What Is Allergic Asthma?

    Allergies are all about your immune system. The job of your immune system is to protect you from germs such as bacteria and viruses. But if you have an allergy, your immune system will also defend your body against a harmless substance -- such as cat dander or dust mites -- that you encounter. When you come across an allergy trigger, your body makes molecules called IgE antibodies. These trigger a series of reactions that can cause swelling, runny nose, and sneezing.

    Dust Mite Prevention

    For prevention of asthma and allergies when you have dust mite allergies, try the following strategies:

    • Encase pillows, mattresses, and box springs with allergen-proof, zippered covers.
    • Wash all bedding in hot water once a week.
    • Don't allow smoking in your house.
    • Wear a mask and gloves when cleaning, vacuuming, or painting to limit dust and chemical exposure.
    • Vacuum twice a week.
    • Limit throw rugs to reduce dust and mold. If you do have rugs, make sure they are washable.
    • When possible, choose hardwood floors instead of carpeting. If you must have carpeting, choose low-pile material.
    • Avoid dust-collecting Venetian blinds or long drapes. Replace old drapes with window shades instead. Washable curtains should be washed in hot water every two to four weeks.
    • Non-carpeted flooring is best. If you cannot get rid of your carpeting, vacuum often with a multi-layer, allergen-proof vacuum bag. Wear a mask while vacuuming. If your child has asthma, do not vacuum while he or she is in the room. Products that eliminate dust mites from carpeting (such as Acarosan) can be purchased. Your asthma care provider can give you information about these products.
    • Dust all surfaces with a damp cloth often, including lampshades and windowsills.
    • Keep clutter under control. Toys and books should be stored in enclosed bookshelves, drawers, or closets.
    • Replace traditional stuffed animals with washable stuffed animals.
    • Keep all clothing in drawers and closets. Keep drawers and closets closed.
    • Cover air ducts with filters or cheesecloth. Change these when soiled.
    • Pillows and bedding should not contain feathers.
    • Keep indoor humidity low (25%-50%). Use a dehumidifier.
    • Regularly change filters on heaters and air conditioners.
