Dust mites are microscopic organisms that feed on flakes of sloughed-off skin. They exist everywhere. Pet dander can be a significant cause of poorly controlled asthma. It is difficult to remove a pet from the house because of strong emotional ties. The minimum effective action is to keep the pet out of the bedroom.
Molds Keep bathrooms clean and dry to reduce molds.
Dry freshly laundered clothes promptly. Remove houseplants because molds grow in the soil. Medications Medications that commonly trigger asthma include aspirin and nonsteroidal anti-inflammatory drugs, and beta blockers, including eye drops for glaucoma. Find a pulmonologist near you.
