Knoxville, Tennessee has been hit especially hard by allergies this year, with pollen counts reaching record highs. Experts attribute the severe allergy season to a combination of climate change and increased rainfall in the region, which has led to higher levels of tree, grass, and weed pollen.

Why it matters

Allergies can significantly impact quality of life, causing symptoms like sneezing, itchy eyes, and difficulty breathing. The Knoxville area has consistently ranked among the worst cities in the country for allergy sufferers, and this year's extreme pollen levels are exacerbating the problem for local residents.

The details

A recent study by the Asthma and Allergy Foundation of America found that Knoxville and nearby Chattanooga are two of the most challenging cities in the US for people with pollen allergies. Warmer temperatures and heavier rainfall over the past decade have contributed to a surge in pollen production from trees, grasses, and weeds in the region.

  • Pollen season in Tennessee typically runs from early spring through late fall.
  • This year, pollen counts in Knoxville have been at record highs since March.
