exercise-induced asthma

[-indyo̅o̅st′]
a form of asthma that produces symptoms after strenuous exercise. The condition usually occurs in persons who already have asthma, hay fever, or related hypersensitivity reactions. The effect may be acute but is reversible.

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.

asthma

paroxysmal dyspnoea characterized by wheezing and difficulty in expiration because of constriction of the airways due to spasm of the bronchial muscle (bronchospasm). Caused by the response of the immune system to a variety of stimuli. Inhaled or oral corticosteroids damp down the acute immune reaction, while inhaled β2-receptor agonists relieve the bronchial spasm. exercise-induced asthma: a number of triggers are now known to produce bronchospasm and reduce performance in sport and exercise. These include intense exercise (especially combined with low fitness), respiratory tract infection, cold environmental temperature, allergens (such as pollen in hay fever), air pollution (especially cigarette smoke), certain drugs (including β-blockers) and simply exercise per se . Different sporting activities vary in likelihood of causing bronchospasm, e.g. it is least likely in the warm humid air of a swimming pool. See also pulmonary function tests, salbutamol.

Another contributing factor to this happening recently could be the fact that the weather has turned much colder and if you're doing your running outdoors, then this will certainly have an impact - exercise induced asthma is far more prevalent during extremes of temperature - so very cold, dry air or at the height of summer when it's very warm and allergen levels are higher.
