Chronic exposure to particulate matter air pollution (PM2.5 ) is associated with chronic rhinosinusitis (CRS). Elevated ambient temperature may increase PM2.5 levels and thereby exacerbate sinonasal symptoms. This study investigates the association between high risk of CRS diagnosis.Patients were diagnosed at Johns Hopkins hospitals from May October 2013-2022, controls matched patients without meanwhile. A total 4752 (2376 cases 2376 controls) identified a mean (SD) age 51.8 (16.8) years. The effect maximum on symptoms was estimated distributed lag nonlinear model (DLNM). Extreme heat defined as 35.0°C (95th percentile distribution). Conditional logistic regression models extreme diagnosis.Exposure increased odds exacerbation (odds ratio [OR] 1.11, 95% confidence interval [CI] 1.03-1.19). cumulative during 0-21 days significant (OR 2.37, CI 1.60-3.50) compared minimum morbidity (MMT) 25.3°C. Associations more pronounced among young middle-aged abnormal weight.We found that short-term diagnosis, suggesting cascading meteorological phenomena. These results highlight climate change's potentially deleterious health effects upper airway diseases, which could have public impact.
