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.
• Shortness of breath
• Tight chest
These symptoms are often worse in cold, dry air. Warm and humid air may lessen the symptoms.
Exercise is a very important aspect of good health, so your allergist / immunologist may prescribe taking medication prior to exercising to control symptoms.
