To decide the perfect and worst cities for dwelling with allergic reactions, the Asthma and Allergy Foundation of America analyzed information from the 100 most-populated metropolitan statistical areas within the decrease 48 states (Alaska and Hawaii weren’t included as a result of they’re typically not included in nationwide pollen monitoring programs.)
In the report, 2023 Allergy Capitals: The Most Challenging Places to Live with Allergies, researchers scored every metro primarily based on 5 components: pollen scores for tree, grass, and weed pollen, over-the-counter allergy remedy use in keeping with the IRI Medication Sales Database, and the variety of of board-certified allergists and immunologists per affected person in every metropolis.
The pollen information for 2022 was collected from Pollen Sense, an automatic sensor community that gives stay pollen and mould counts. Days with “very high” pollen counts had the next weight than “high” days for calculation of pollen scores.
The Centers for Disease Control and Prevention says that as local weather change results in shifts in precipitation patterns, extra frost-free days, hotter seasonal air temperatures, and extra carbon dioxide within the ambiance, the size and timing of pollen seasons modifications.
A hotter local weather and longer rising season may clarify why seven of the 20 worst allergy cities the AAFA’s report are in Florida.

And don’t suppose you’ll be able to escape allergic reactions by being within the metropolis. Many of the well being impacts of local weather change are felt extra in city facilities due to an impact known as an “urban heat island” by which buildings, roads, infrastructure, inhabitants density, and a scarcity of inexperienced area could make cities a number of levels hotter than close by extra rural areas, the AAFA says in its report. Climate change is anticipated to accentuate the UHI impact, the report says.
Based on the rating by the AAFA, these are the 30 worst cities for individuals who endure allergic reactions.
