Asthma triggers directory

Asthma triggers vary from person to person and can range from allergens or environmental irritants, to health conditions that cause asthma. Identifying your individual allergy triggers is crucial in helping prevent and treat your asthma. Common allergens include certain foods, dust mites, indoor mould, pets and pollen. Common irritants include smoke, household sprays, perfume or paints. Other triggers may include exercise, colds or infections, certain types of weather, stress and some medications.
