The Impact of Climate, Aeroallergens, Pollution, and Altitude on Exercise-Induced Bronchoconstriction.

Exercise-induced bronchoconstriction (EIB) with or without underlying asthma is a condition with complex pathophysiology, where many factors play a role in its development and clinical presentation. EIB can be impacted by various environmental factors including climate, environmental allergens, air pollution, and altitude. Although it might be hard to escape one's environment, patients should nevertheless be counseled on how the environment could impact their symptoms. Patient education regarding environmental factors could help overcome impediments to exercise and improve performance.
