Allergy season is getting longer because of climate change
March 6, 2025
Allergy season is starting earlier — and lasting longer — as climate change heats up cities across the U.S. While the spring allergy season usually starts in March, more warm weather earlier in the year means people might begin experiencing symptoms in February, or even January, said Ahmad Sedaghat, MD, PhD, professor and director of the Division of Rhinology, Allergy and Anterior Skull Base Surgery in the Department of Otolaryngology at the University of Cincinnati College of Medicine.
