Asthma
The best way to deal with asthma triggers is to learn what they are and avoid them if possible, and if not totally avoidable then adjust one's behavior to deal with them. Example: running on a cold winter day right up to the doorstep of a warm house and going immediately inside; the sudden temperature change can cause an attack and could have been avoided.  In general but especially with a medical condition such as asthma it is necessary to be aware of one's environment and what's in it, both indoors and outdoors. Most often the Asthma is triggered by allergens. One big source of allergens is the carpet.
