Abstract Background Chronic exposure to particulate matter air pollution (PM 2.5 ) is associated with chronic rhinosinusitis (CRS). Elevated ambient temperature may increase PM 2.5 levels and thereby exacerbate sinonasal symptoms. This study investigates the association between high ambient temperature and the risk of CRS diagnosis. Methods Patients with CRS were diagnosed at Johns Hopkins hospitals from May to October 2013–2022, and controls were matched patients without CRS meanwhile. A total of 4752 patients (2376 cases and 2376 controls) were identified with a mean (SD) age of 51.8 (16.8) years. The effect of maximum ambient temperature on symptoms was estimated with a distributed lag nonlinear model (DLNM). Extreme heat was defined as 35.0°C (95 th percentile of the maximum temperature distribution). Conditional logistic regression models estimated the association between extreme heat and the risk of CRS diagnosis. Results Exposure to extreme heat was associated with increased odds of exacerbation of CRS symptoms (odds ratio [OR] 1.11, 95% confidence interval [CI] 1.03–1.19). The cumulative effect of extreme heat during 0–21 lag days was significant (OR 2.37, 95% CI 1.60–3.50) compared with the minimum morbidity temperature (MMT) at 25.3°C. Associations were more pronounced among young and middle‐aged patients and patients with abnormal weight. Conclusions We found that short‐term exposure to high ambient temperature is associated with increased CRS diagnosis, suggesting...
