Exercise-Induced Bronchoconstriction, (EIB), often known as exercise-induced asthma, is a narrowing of the airways causing difficulty moving air out of the lungs during exercise. If you have chronic asthma, your symptoms may be worse when you exercise. In addition, some people who don’t have asthma experience symptoms only when they exercise.
These symptoms include:
These symptoms are often worse in cold, dry air. Warm and humid air may lessen the symptoms. This can be easily controlled with use of medication taken prior to exercising.
