Controlling Your Triggers: Allergens
For many people with lung problems such as asthma or COPD, inhaling allergens leads to inflamed airways. Allergens also cause symptoms of nasal allergies. Do your best to avoid allergens that trigger symptoms. The tips below reduce your exposure to allergens. You don’t have to try all the tips at once. Check off a few from the lists below, and start with those.
Dust mites are tiny bugs too small to see or feel. But they can be a major trigger for allergy and asthma symptoms. Dust mites live in mattresses, bedding, carpets, curtains, and indoor dust. They thrive in warm, moist environments.
Wash bedding in hot water (130°F) each week. This kills the dust mites.
Cover mattress and pillows with special dust-mite-proof cases called hypoallergenic casings.
Don’t use upholstered furniture in the bedroom.
Use allergy-proof filters for air conditioners and furnaces. Follow manufacturer instructions for maintaining and replacing filters.
If you can, replace wall-to-wall carpets with wood, tile, or linoleum floors—especially in the bedroom.
Animals with fur or feathers often produce allergens. These are shed as tiny particles called dander. Dander can float through the air or stick to carpet, clothing, and household furniture.
It’s best to choose a pet that doesn’t have fur or feathers, such as a fish or a reptile.
Keep pets with fur or feathers out of your home. If you can’t do this, be sure to keep them out of your bedroom.
Wash your hands and clothes after handling pets.
Mold grows in damp places, such as bathrooms, basements, and closets.
Clean damp areas weekly to prevent mold growth. This includes shower stalls and sinks.
Run an exhaust fan while bathing. Or, leave a window open in the bathroom.
Repair water leaks in or around your home.
Have someone else cut grass or rake leaves, if possible.
Don’t use vaporizers, humidifiers, or evaporative (swamp) coolers. These put water into the air and encourage mold growth.
Pollen from trees, grasses, and weeds is a common allergen. (Flower pollens are generally not a problem.)
Try to learn what types of pollen affect you most. Pollen levels vary depending on the plant, the season, and the time of day.
Use air conditioning instead of opening the windows in your home or car. Set the dial to recirculate the air, so less pollen gets in.
Have someone else do yardwork, if possible.
Cockroaches are a common household pest. They also produce allergens.
Keep your kitchen clean and dry. A leaky faucet or drain can attract roaches.
Remove garbage from your home daily.
Store food in tightly sealed containers. Wash dishes promptly.
Use bait stations or traps to control roaches. Avoid using chemical sprays.
