More Sweat Equals Lower Risk of Exercise-Induced Asthma
...pine. In other words, the more hyperactive the airway, the less the sweat production.
The average sweating rates of those who didn't respond to the methacholine
were higher -- and they didn't have asthma.

The researchers used the objective measure of choice in epidemiological studies on asthmaBR in response to a methacholine

Asthma Breath Test in Diagnosis of Chronic Cough
