hings that cause asthma episodes are known as triggers. Many asthma triggers are found outdoors.

Air pollution

Air pollution can trigger asthma. Even healthy people can have trouble breathing on high air pollution days. The main air pollution triggers are small particles (also known as particulate matter) and ground level ozone. These triggers come from:

  • Smoke
  • Dust
  • Emissions from cars and buses
  • Emissions from factories
  • Pesticides and other chemical sprays

Weather

Cold air, humid air, and changes in the weather can trigger asthma.

Allergens

Not all people with asthma have allergies, but for those who do, outdoor allergens may trigger asthma. Common outdoor allergens that trigger asthma episodes include:

  • Pollen
  • Pets
  • Grass
  • Trees

What can you do?

  • Monitor air pollution levels using the Air Quality Index at www.airnow.gov
  • Limit outdoor activities when the Air Quality Index reports unhealthy levels.
  • Limit outdoor activities during very cold or very humid weather.
  • Talk to a doctor about how allergies affect asthma. Some people with asthma and allergies may need to take both allergy and asthma medicines.
