Common asthma triggers

Many of the same substances that trigger allergies can also trigger asthma. Common allergens include pollen, dust mites, mold, and pet dander. Other asthma triggers include infections and irritants like smoke, pollution, fumes, cleaning chemicals, and sprays. Avoiding exposure to known allergens and respiratory irritants can substantially prevent or reduce asthma symptoms.
