Did you know that today is World Asthma Day? And it’s a great day to feature asthma education during Air Quality Awareness Week. May is also Asthma Awareness Month — a time to educate friends, family, and patients about asthma and promote awareness about how Being Air Aware and Prepared can help control this serious, sometimes life-threatening, chronic respiratory disease.

What is Asthma?

Why is Coco Red Book Cover

Asthma is a long-term disease that inflames and narrows your lungs’ airways. Have you ever tried to breathe through a flat straw? It makes breathing harder and can be scary. That’s how people who have asthma can feel when they are exposed to pollutants like dirty air, whether it’s from ozone, wildfire smoke or other pollution. We can all be prepared by checking the local air quality forecast at

If you have asthma, or know someone who does, learn more about asthma:

Avoid Air Pollution Triggers 

People with asthma and other lung diseases usually know when they’re having a reaction, but what can you do to avoid it?

  1. First, know what your local Air Quality Index (AQI) forecast is for the day. If the AQI forecast is in the unhealthy categories, you can take appropriate measures and have your asthma action plan ready.
  2. Check your AQI before you go outside to know what steps to take. Reducing time being active outside, reducing your activity level, or even changing the time of day that you are outside can protect your lungs from air pollution. Learn how to use the AQI to reduce your exposure to air pollution.
  3. If there is smoke in the air, check the Fire and Smoke Map for the latest information about the AQI in your area. Wildfire smoke can make the outdoor air unhealthy to breathe. Smoke from outdoors can also enter your home and make it unhealthy to breathe indoor air. EPA has developed materials on how to reduce or remove polluted air inside of homes and buildings.
