Hay Fever (Seasonal Allergies)

Reviewed by the Nimbera editorial team · Last updated May 2026

Seasonal allergic rhinitis causes sneezing, nasal congestion, runny nose, and itchy eyes triggered by airborne allergens like pollen, mold spores, or dust mites. The immune system mounts an exaggerated IgE-mediated response to otherwise harmless particles.

When to see a doctor

See a doctor if allergy symptoms severely disrupt sleep or daily functioning, if you develop wheezing or difficulty breathing, or if OTC antihistamines are no longer controlling your symptoms adequately.
