Asthma triggers include pollen, mold, animal dander, and air pollutants such as tobacco smoke.

Common asthma triggers are dust mites, pets and pet dander, cockroaches, mold, tobacco smoke and pollen.

Pollen is the most common cause of seasonal allergic rhinitis, sometimes known as "hay fever."

Mold spores or fragments may be inhaled through the nose and into the lungs, where they cause allergic reactions or asthma.

People with asthma, allergies, or other breathing conditions may be more sensitive to mold.

Household pets, like cats and dogs, are the most common sources of animal allergens.

Dust mites are microscopic organisms that can live and thrive throughout homes and businesses.

It's not the dust mite itself that causes trouble for people, but its shed skin and fecal matter. These substances bring misery to millions of allergy sufferers.

Autumn means pumpkins, colorful leaves and, for some, worries about asthma.

For many allergy sufferers, pollen and mold are the main problems.

If you think you may have allergies, talk with your health care provider about getting tested.
