How is it that swimming is good for asthma?
I have asthma (minor, but still, I have it), and I’ve been told that swimming is the best thing an asmatic can do.
Why is that? I know that all arobic exercises are good for your asthma but swimming seems to be the first things people tell you is good. So, why swimming as opposed to say, jogging or biking.
I’m just curious, considering starting a regular swimming workout. Thanks.

This is for people with Asthma:
Are some kinds of exercise worse than others?
Yes.
If you take different kinds of exercise so that you use the same amount of oxygen in each one, some will cause more wheeziness or chest tightness than others. Running outdoors will in general be worse than swimming. In fact swimming is one of the best forms of exercise for people with asthma because it usually causes the least amount of chest tightness. Running indoors on a treadmill, or cycling on an indoor exercise bike will come somewhere between outdoor running and swimming.
Other factors influence the amount of worsening of your breathing which you get from a particular form of exercise. Generally for example, if the air you breathe is cold and dry, the asthma will be worse. If it is warm and moist, the asthma will be less bad. This explains why swimming generally causes less asthma than outdoor running.
