exercise-induced asthma

A condition in which intense physical exertion results in acute airway narrowing in individuals with airway hyperreactivity.
 
Clinical findings
Cough, wheezing, dyspnoea, cough, chest tightness, hyperinflation, airflow limitation and hypoxia.
 
Pathogenesis
EIA is closely linked to thermal provocation, which occurs when large volumes of cold air are “conditioned” (heated and humidified), a scenario most common in winter. The limit of airflow is most intense with running, less so with jogging and least with walking; the obstruction is greatest with cold, dry air, and least with warm, humid air.
