With spring’s arrival, allergy season is in full swing across the U.S. Tree, grass, and ragweed pollen are the main culprits, with severe levels expected from the Gulf Coast to the Pacific Northwest. AccuWeather experts warn of heightened allergy conditions due to a warm, wet start to summer. Nearly 25% of adults and 20% of children suffer from seasonal allergies. To manage symptoms, avoid outdoor exposure in the early morning, embrace post-rain relief, and keep homes pollen-free. The extended allergy season will last through the summer.
