Seasonal Allergies Might Increase Suicide Rate, Study Says

MONDAY, Oct. 6, 2025 (HealthDay News) — Seasonal allergies are considered an annoyance to most, and maddening to some.

High pollen counts are linked to a significant increase in suicide risk, according to findings published in the December issue of the Journal of Health Economics as the U.S. enters fall allergy season.

Further, suicide risk increases as airborne levels of pollen rise, researchers found.
