Exercise & the Small Airways
The role of the small airways in EIA and EIB is not well understood, but exercise may enhance the deep effects of exposure to allergens and irritants. Increased minute ventilation during physical activity pulls aeroallergens and pollutants deeper into the lungs. Indeed, some of the differences between the capacities of various sports to cause EIB may relate to environmental factors affecting the smaller airways, including exposure to seasonal and perennial allergens in sensitized individuals, cold or dry air and pollutants.
