The extended allergy season poses health risks for millions of Americans, particularly those with ragweed allergies or asthma. Prolonged exposure to pollen can lead to more severe allergy symptoms, including sneezing, congestion, and respiratory issues. Urban areas may face heightened risks due to the urban heat island effect, which accelerates ragweed growth and pollen production. Additionally, mold spores, which peak in late summer and fall, can exacerbate allergies and asthma. The combination of longer pollen seasons and increased mold activity could lead to a rise in allergy-related health issues, particularly in regions experiencing the most significant warming trends.
