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 irritants like smoke, pollution, fumes, cleaning chemicals, and sprays. Asthma symptoms can be substantially reduced by avoiding exposure to known allergens and respiratory irritants.
