Reducing allergy, asthma triggers at home is key.
Allergies are diseases of the immune system that cause an overreaction to substances called "allergens." Allergies, as well as the most common type of asthma, are triggered by year-round inhaled allergens such as dust mites, pet dander and mold.
Asthma is a chronic pulmonary condition in which the airways become blocked or narrowed when stimulated by allergens or other environmental triggers.
If you suffer from allergies or asthma--or both--you aren't alone. Asthma and allergies strike 25 percent of Americans. Asthma, however, is even higher among blacks, who have more asthma attacks than whites and are more likely to be hospitalized for the disease.
"Studies have shown that if the major indoor triggers of asthma were all eliminated, asthma attacks could be decreased by 60 percent," says Norman H. Edelman, MD, chief medical officer for the American Lung Association.
What's at the top of the hit list?
"Cigarette smoke," Edelman says. "Any home in which a person with asthma and allergies lives should be absolutely off limits to smoking, with no exceptions made."
1 FIGHT THE MITE
Enclose pillows and mattresses in allergen-impermeable covers, or wash your pillows every week in hot water and dry thoroughly. Also, consider removing wall-to-wall carpeting and replacing it with tile or wood floors.
If that's not an option, vacuum often with a vacuum cleaner equipped with a high-efficiency purifying air filtration system, also known as a HEPA system. And don't forget to toss the bag in the trash after vacuuming, because dust mites can escape.
2 BUST THE DUST
Thousands of microscopic spiders, called dust mites, live in a pinch of house dust. Dust mites feed on skin flakes and can be found throughout the home. The tiny pests produce airborne particles that can trigger allergic reactions or asthma attacks when inhaled.
Dust mites thrive in moist air, so reducing moisture is your best weapon. Use a dehumidifier to maintain the relative humidity in your home below 50 percent, says Steven Kernerman, DO, an asthma and allergy specialist in Spokane, Wash.
An inexpensive device known as a hygrometer, available at hardware stores, is handy for measuring relative humidity, Kernerman says.
3 PUT MOLD ON HOLD
High indoor humidity can encourage the growth of mold, another common culprit of allergy and asthma symptoms. Indoor mold is commonly found in basements, bathrooms, closets, attics, old mattresses, pillows and blankets. Limit opportunities for mold to grow by removing carpeting and wallpaper in basements and bathrooms. Use diluted bleach to eliminate visible mold growth in showers and on shower curtains.
4 PLUG THE BUGS
Cockroaches leave droppings that can trigger allergic reactions and asthma episodes when inhaled. A study funded by the National Institute of Allergy and Infectious Diseases found that the combination of cockroach allergy and exposure to the creatures is a major cause of asthma-related illness and hospitalizations among children living in densely populated urban areas.
Keep cockroaches at bay by plugging up crevices around the house, storing food and garbage in closed containers and mopping the kitchen floor at least once a week.
Almost all pets, furry or feathered, can trigger asthma and allergies. Pets that trigger symptoms should be removed from the home, allergists say. Otherwise, keep them out of the bedroom. As lovable as they are, they all leave dander on beds, floors and furniture.
