City air and nighttime asthma: a new clue?
NCT ID NCT03406351
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how air pollution and the body's internal clock (circadian rhythm) interact to worsen asthma, especially at night. Researchers will measure tiny molecules called microRNAs in the sputum of 20 adults with and without asthma over 48 hours. The goal is to understand why asthma symptoms often spike at night and how pollution plays a role.
