No and yes,  First of all, asthma is very treatable. If you can’t do your normal activities or are unable to exercise as much as you want, then there is something wrong with your asthma treatment program.  There are Olympic athletes (e.g., Jacki Joyner-Kersey) who have significant asthma! In general, there are very few activities that asthmatics need to avoid.

So, having asthma is no excuse for being a couch potato.  It is a shame that some asthmatic children are kept from physical education classes or recess, because they are not being treated appropriately for their asthma.  In fact, some experts theorize that inactivity can . over the long run, worsen asthma.

If your asthma is not under control, then you should limit your activity briefly until you can get adequately be your doctor.  It is the rare asthmatic who has such severe symptoms that they must  limit their activity despite maximal medical treatment.
