What is Asthma?
Asthma is a disease that affects your lungs. It causes repeated episodes of wheezing, breathlessness, chest tightness, and nighttime or early morning coughing. Asthma can be controlled by taking medicine and avoiding the triggers that can cause an attack. You must also remove the triggers in your environment that can make your asthma worse. 

An asthma attack can occur when you are exposed to things in the environment such as house dust mites and tobacco smoke. These are called asthma triggers.
 

• Environmental Tobacco Smoke (Secondhand Smoke)Dust Mites
• Outdoor Air Pollution
• Cockroach Allergen
• Pets
• Mold
• Strenuous Physical Exercise
• Some medicines
• Bad weather such as thunderstorms, high humidity, or freezing temperatures
• Some foods and food additives
• Strong emotional states can also lead to hyperventilation and an asthma attack.

Learn what triggers your attacks so that you can avoid the triggers whenever possible and be alert for a possible attack when the triggers cannot be avoided.
