Irritants and allergens can effect people with asthma who have inflamed airways. Asthmatics can be sensitive to things which may not bother other people. These things are called “triggers.”


Triggers can be irritants or allergens. This graphic shows many of the irritants and allergens that may be in the air in a home.

  • Irritants: Non-allergic triggers (irritants) including smoke, pollution or cold air can, at some level, irritate everybody.
  • Allergens: Asthma is often caused by allergies and exposure to allergens such as pets, dust mites or mold

Irritants do not mount IgE antibodies and thus cannot be tested via skin testing and can not lead to an allergic reaction. But if you have underlying allergies or asthma, your sensitivity to irritants can be higher.
