Summary

This study tested a cold air breathing challenge in 60 adults (healthy and with asthma) to see if it can safely tell the difference between asthma and normal lungs. Participants breathed cold, dry air while their lung function was measured. The goal is to develop a better, more reliable test for diagnosing asthma and exercise-related breathing problems.
