<s>[INST] What Causes an Asthma Attack? [/INST] An asthma attack can happen when you are exposed to “asthma triggers.” Your asthma triggers can be very different from someone else’s asthma triggers. Know your triggers and learn how to avoid them. Watch out for an attack when you can’t avoid your triggers. Some of the most common triggers are tobacco smoke, dust mites, outdoor air pollution, cockroach allergen, pets, mold, smoke from burning wood or grass, and infections like flu.
