NCT ID NCT05773001
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether having a respiratory infection in the past changes how your lungs react to ozone, a common air pollutant. One hundred healthy adults will breathe ozone while exercising and have their lung cells sampled. The goal is to understand why some people may be more susceptible to lung inflammation after environmental exposures.
