According to the Environmental Protection Agency (EPA), Americans spend up to 90% of their time indoors. Many indoor allergens and irritants can play a significant role in triggering asthma attacks.

Indoor Asthma Triggers

Indoor asthma triggers include mold, tobacco smoke, cleaning supplies, pets, pests and pesticides, gas stoves, and other irritants. See Asthma Triggers at Home (Spanish) and EPA Indoor Environmental Asthma Triggers for additional information on indoor asthma triggers.

Molds are fungi. People are regularly exposed to 200 different fungi. Mold can be an asthma trigger. There is no way to completely avoid exposure to molds, but controlling moisture in the home is the best way to reduce mold in the home. The below resources provide additional information on mold andasthma in Utah.

Cleaning Supplies

Chemicals in market cleaning supplies can be a trigger for asthma. See Asthma-friendly cleaning supplies (Spanish) for asthma-friendly home cleaning formulas.
