Things That Can Cause Asthma and Allergies
Am Fam Physician. 2002 Aug 1;66(3):429-430.
Controlling dust mites is the most important thing you can do in your house to make your asthma and allergies better. Dust mites are tiny bugs that cannot be seen. They live in places that collect dust. Pillows, mattresses, and carpets usually have thousands of dust mites living in them. People can become allergic to dust mites and their waste products. To control dust mites you should:
Cover your pillows and mattresses with vinyl or semipermeable covers.
Wash your sheets, pillowcases, and comforters every one to two weeks in hot water (at least 130°F).
Remove carpet from the bedroom or carpet that is laid over concrete.
Avoid lying or sleeping on upholstered furniture.
Clean uncarpeted floors with a wet mop every week.
Reduce indoor humidity to 50 percent or less.
Pets can sometimes cause allergy problems. People can become allergic to parts of the animal's skin, saliva, and waste products. Your doctor can do tests to see if you are allergic to your pet. If you are, you should:
Permanently remove your pets from the house. This is the best way to make your asthma and allergies better.
Keep pets out of the bedroom and off of carpet and upholstered furniture, if you're unable to remove them.
Some people are allergic to cockroaches. To get rid of cockroaches you should:
Keep the kitchen very clean.
Avoid leaving food or drink out.
Use pesticides to kill the cockroaches, if necessary.
Pollens and outdoor molds
Pollens and outdoor molds come and go depending on the weather and time of year. To avoid pollen and outdoor molds you should:
Find out when the pollen and mold counts are high in your area. These counts can be found on your local TV stations and allergy Web sites (see Resources).
Avoid going outside when pollen and mold counts are high.
Indoor molds need moisture to grow. To control indoor mold you should:
Fix all water leaks and damp areas associated with mold growth.
Use a dehumidifier to keep your basement dry.
Reduce the humidity in your house to 50 percent or less.
If you have asthma, you should avoid all exposure to tobacco smoke.
Don't exercise outdoors when pollution levels are high.
