Asthma Triggers

Asthma triggers are irritants that can provoke asthma symptoms or attacks. There are many triggers that can aggravate asthma symptoms, and they often differ from person to person. You can help prevent bothersome asthma symptoms by identifying and avoiding known triggers. In fact, identifying and avoiding triggers should be part of a detailed plan of action to help manage your asthma successfully.

While it may not be possible to completely eliminate asthma triggers, you should still try to remove as many as possible from home and work surroundings. This can help you or others with asthma enjoy a healthier life with fewer asthma symptoms and attacks.

People with asthma should stay away from things or "triggers" that make their asthma worse. Common asthma triggers may include:

  • Tobacco or wood smoke
  • Dust mites
  • Animal dander
  • Cold air
  • Cockroach droppings and remains
  • Strong odors
  • Pollen
  • Smog
  • Exercise
  • Viral upper respiratory infections (for example, colds)
  • Indoor mold
