What triggers an asthma attack?

House dust, insecticides, cigarette and other smoke, animals with fur, emotional upsets, plant pollen, changes in weather, colds and physical strain.

These are just a few of the "triggers" that can cause asthma attacks. Different people are sensitive to different triggers. If you have asthma, it is important for you to identify your asthma triggers and to avoid them as far as possible.
