Perform this routine 15 or 30 minutes before you race or run. The intensity of this warmup results in a refractory period of about 60 to 90 minutes during which you should be able to exercise without an asthma attack. If you have allergies and notice more frequent asthma attacks during the spring and late summer, wearing a mask may help then as well. Always inhale through the nose. Also, beware of air pollution, and remember that you will have more trouble breathing at high altitude.
Anxiety can exacerbate an asthma attack.
Some experts recommend 30-minute relaxation or meditation sessions several times a week to teach you to relax readily at times of stress. If you can't run for long without an attack no matter what you do, try running at intervals of 3 to 5 minutes with 2 to 3 minutes' rest between. Eventually you should build up some endurance and be able to run longer. The bottom line is that exercise is excellent for asthma. Home remedies may not be enough.
