Spring's warmer temperatures provide relief from winter, but for millions of Americans with allergies, the season also ushers in a surge of pollen, triggering sneezing, headaches, and watery eyes. Cities like Atlanta and Houston have already broken pollen count records, with trees like pine, oak, and birch contributing to the wave of allergens. The Asthma and Allergy Foundation of America (AAFA) predicts another severe allergy season in 2026, especially in the southern US, as seasonal allergies continue to worsen for many. Climate change plays a significant role in this increasing allergy burden. Rising temperatures and higher levels of carbon dioxide cause plants to produce more pollen and extend the growing season. For instance, tree pollen season now begins 20 days earlier than it did 30 years ago. Kenneth Mendez of the AAFA says more people are developing allergies, including those without a prior history, due to increasing pollen levels. Allergies, while typically a nuisance, contribute to lost productivity and healthcare costs. Some individuals face more severe reactions, including asthma attacks and even emergency room visits due to tree pollen. As pollen seasons lengthen, it's also harder to escape allergens, which sneak indoors on clothing, pets, and through vents. To help manage symptoms, allergists recommend starting medication early, limiting outdoor activity during peak pollen times, and using HEPA filters at home. Reducing emissions is key to tackling both climate change and the growing allergy problem.
