The Asthma and Allergy Foundation of America (AAFA) has ranked Greenville, South Carolina as the 10th most challenging city in the United States for seasonal pollen allergies. The city was evaluated based on local pollen levels, over-the-counter allergy medication usage, and the availability of board-certified allergists.

Why it matters

Greenville's high ranking reflects the significant impact that seasonal allergies have on the health and quality of life for many residents in the region. The combination of geography, weather, and timing of pollen seasons makes the Upstate one of the most difficult areas in the country for allergy sufferers.

The details

The AAFA evaluated 100 U.S. metro areas and found that Boise, Idaho was identified as the most challenging city for seasonal allergies. Greenville's ranking of 10th place puts it among the top 10 most difficult areas for allergy sufferers nationwide. Factors like high pollen counts for trees, grass, and weeds, as well as the widespread use of over-the-counter allergy medications, contributed to Greenville's placement on the list.
