Allergy Season Arrives Earlier in 2026, Prompting Early Prep

Allergy seasons in 2026 are starting earlier and lasting longer across the U.S. due to rising temperatures from climate change, with the Southeast already reporting symptoms. Experts urge proactive management: start allergy meds early (24-hour antihistamines often work best), choose appropriate options (nasal or steroid sprays if needed), keep windows closed at night to avoid morning pollen, change clothes and shower after outdoor exposure to prevent spreading pollen indoors, and address dust mites and pet dander with regular cleaning and HEPA filtration.
