Things that cause asthma (AZZ-muh) attacks or make asthma worse are called triggers. Asthma triggers can be found in your home, your child's school, child care, and other people's homes.

Common Asthma Triggers

Allergens (AL-er-jinz) are things your child may be allergic to.

Sinus (SYE-nis) and lung infections. The sinuses are spaces inside your head, behind your nose. They can get infected. Pneumonia (nuh-MOH-nyuh) is a kind of lung infection.

Things your child breathes in.

Exercise. Some people with asthma wheeze*, cough, and get a tight feeling in the chest when they exercise. But they can still be active. There are medicines to use before exercise.

Avoiding Triggers

You can't get rid of all the asthma triggers in your home. But there's still a lot you can do. Here are some tips:

Don't smoke. And don't let anyone else smoke in your home or car.

Protect your child from dust and dust mites.

Keep pets away.

Control cockroaches.

Prevent mold. Floods, leaks, or dampness in the air can cause mold.

Keep pollen away. If your child has hay fever:

Keep strong smells out of the house.

Keep your child indoors when the air quality is very poor. Air quality is how clean or dirty the air is. It can change from day to day.

What Is Asthma?

Asthma is a disease of the breathing tubes that carry air to the lungs. The linings of the tubes swell and they fill up with mucus (MYOO-kus). This is called inflammation (in-fluh-MAY-shun). It makes the tubes get narrow. This makes it hard to breathe

Asthma can cause sickness, hospital stays, and even death. But children with asthma can live normal lives.
