Allergy Seasons Are Getting Longer
Monday, May 11th, 2026
If your seasonal allergies seem worse than they used to, national allergy experts say there’s a reason for it. Several leading organizations — including the American Academy of Allergy, Asthma & Immunology (AAAAI), the Asthma and Allergy Foundation of America (AAFA), and the American College of Allergy, Asthma & Immunology (ACAAI) — are reporting that allergy seasons across the United States are becoming longer, more intense, and more difficult to manage.
At Allergy Specialists of Knoxville, we’re seeing many East Tennessee patients experiencing stronger symptoms this spring. Here’s what national allergy experts are saying — and what it means for your health.
AAAAI: Climate Change Is Increasing Allergy Burden
In a recent statement, the American Academy of Allergy, Asthma & Immunology (AAAAI) warned that rising temperatures and increased atmospheric carbon dioxide are contributing to increased pollen exposure and worsening allergic disease outcomes.
According to AAAAI, research published in their medical journals shows that climate-related environmental changes are linked to:
- Longer pollen seasons
- Increased pollen production
- Higher allergen exposure
- Reduced air quality
- Worsening asthma and allergy symptoms
AAAAI emphasized that these environmental shifts are having measurable effects on patients with allergic rhinitis and asthma. :contentReference[oaicite:0]{index=0}
AAFA’s 2026 Allergy Capitals Report Highlights Growing Challenges
The Asthma and Allergy Foundation of America (AAFA) recently released its annual Allergy Capitals® Report, which ranks the most challenging cities in the United States for people living with seasonal allergies.
According to AAFA, longer and more intense pollen seasons are becoming a nationwide health concern. The organization notes that warmer temperatures and extreme weather patterns are helping pollen seasons begin earlier, last longer, and produce more pollen overall.
AAFA reports that more than 106 million Americans experience allergies each year, with seasonal pollen allergies continuing to increase in severity. :contentReference[oaicite:1]{index=1}
ACAAI Warns Spring Allergy Seasons Are Arriving Earlier
The American College of Allergy, Asthma & Immunology (ACAAI) also recently warned patients to prepare early for spring allergy season.
According to ACAAI allergists, tree pollen remains one of the most common and problematic spring allergy triggers. They note that high pollen counts can significantly affect quality of life for sensitive individuals — especially when symptoms are left untreated.
Experts recommend starting allergy medications before symptoms peak and seeking professional evaluation if symptoms interfere with sleep, breathing, or daily activities. :contentReference[oaicite:2]{index=2}
What This Means for Knoxville Allergy Sufferers
East Tennessee’s climate already creates ideal conditions for seasonal allergies. With warmer temperatures and longer growing seasons, Knoxville residents may notice:
- Earlier spring allergy symptoms
- Longer-lasting pollen exposure
- More severe congestion, sneezing, and itchy eyes
- Worsening asthma symptoms during high pollen periods
Many patients who previously managed symptoms with over-the-counter medications may now require more comprehensive treatment strategies.
How to Protect Yourself During Peak Allergy Season
- Monitor daily pollen forecasts

Most importantly, don’t ignore persistent symptoms that affect your quality of life.
