Warmer Winters Fuel Harsher Allergy Seasons, Experts Say

Seasonal allergies are hitting harder this year, and rising temperatures may be to blame, according to health experts.

Warmer winters are leading to earlier and more intense allergy seasons, said Dr. Purvi Parikh, an allergist and immunologist based in New York. “There’s higher amounts of pollen due to rising greenhouse gases and more CO2 in the air, which plants thrive off of,” Parikh explained in a May 2023 interview.

The increased presence of allergens such as pollen, mold, and dust is triggering more severe symptoms. Shelby Harris, a clinical psychologist specializing in behavioral sleep medicine, explained that our bodies see allergens as a threat, which causes the release of histamine.

Experts recommend a few key strategies to manage symptoms. Keeping windows closed during early mornings—when pollen counts are highest—can help reduce exposure indoors. Parikh also advises changing clothes, removing shoes, and showering immediately after returning home to minimize pollen spread. Additional tips include frequent vacuuming, using air purifiers, and avoiding the use of ceiling fans in bedrooms.

Medication remains a frontline defense. Parikh recommends over-the-counter options like Claritin, Zyrtec, Allegra, Flonase, and Astepro. She warned that symptoms like wheezing or shortness of breath should be evaluated by a physician, as they may indicate asthma—a potentially life-threatening condition.

Some also turn to local honey as a natural remedy. Though scientific backing is limited, proponents suggest ingesting local pollens may build immunity. “One spoon a day every morning is the recommended dosage,” said beekeeper Andrew Cote. However, Dr. Timothy Wong cautioned against honey for those allergic to bees or under one year of age.
