What is exercise-induced bronchoconstriction?

Exercise-induced bronchoconstriction refers to the physiological response where the airways narrow in response to exercise, often occurring during or after physical activity. This can lead to symptoms such as wheezing, coughing, shortness of breath, or chest tightness in individuals, especially those with underlying conditions like asthma.

The focus on narrowing airways while exercising is critical because it distinguishes this phenomenon from other respiratory issues that may arise from different triggers or contexts. For example, a chronic cough during physical activity could have various causes and isn't necessarily confined to bronchoconstriction. Similarly, difficulty breathing while at rest typically indicates an ongoing respiratory concern rather than a condition triggered by exertion. Additionally, while exercise-induced bronchoconstriction can be observed in children, it is not exclusive to them and can occur in adults as well, especially those with asthma or exercise-induced asthma.
