Asthma flare-ups can be started by things known as triggers. Do you know what can trigger asthma? Test your knowledge.
Pet birds can cause asthma flare-ups in some people—as can dogs and cats. This is because things such as fur, dry skin flakes (dander), feathers, droppings, and saliva may be asthma triggers.
You can protect yourself by choosing a pet that doesn’t have fur or feathers, such as a fish or a reptile. Wash your hands and clothes after handling pets with fur or feathers. Dander can float through the air or stick to carpet, clothing, and furniture.

Limit outdoor activity if a certain type of weather affects you. Protect your lungs in cold weather by wearing a scarf over your mouth and nose.
Vehicle exhaust and other air pollutants combine to create smog. This can be a trigger. Read or listen to local air quality reports. These let you know when air quality is poor. Stay indoors as much as you can on smoggy days. If possible, use air conditioning instead of opening the windows. In your car, set air conditioning to recirculate air, so less pollution gets in.
Any kind of smoke can trigger asthma flare-ups. If you smoke, think about quitting. And stay away from others who smoke. Smoke from fires or cooking can also cause asthma flare-ups.
