Something that is an asthma trigger in one person may not be an asthma trigger in another person. Asthma triggers can include cigarette smoke, pollen, cold weather, dust mites, pet dander -- even cockroaches. It's important for people with asthma to avoid the specific asthma trigger or triggers that bring on or worsen their symptoms.
