About Asthma

What is Asthma?

Asthma is very common among children, teens and adults. It is a disease that causes the airways of the lungs to tighten.

An asthma attack is when your lungs aren’t getting enough air to breathe. Your child might be having an asthma attack if he or she has:

  • Trouble breathing
  • Wheezing
  • Coughing
  • Chest pain
  • Chest tightness

What are Triggers?

Things that cause asthma attacks are called triggers. Triggers are everywhere.

Indoor Triggers

Any home can be full of triggers like mold, dust mites, secondhand smoke, wood smoke, cockroaches, cats and dogs.  Learn more about indoor triggers.


Outdoor Triggers

Other asthma triggers may be air pollution (such as ozone, small particles, and pollen).  
Learn more about outdoor triggers.

Asthma Action Plan

Asthma cannot be cured. But, with the help of a doctor and an asthma action plan, you can make sure your child stays active and healthy.



Asthma control is about more than just treating sudden asthma symptoms. Asthma control is about managing your asthma daily so you may avoid asthma symptoms in the first place. Outdoor air pollution can make asthma worse. You can check your daily air quality forecast by visiting AIRNOW.
