Cottonwood trees are known for producing fluffy, cotton-like seeds and pollen that can trigger seasonal allergies. In spring, their pollen becomes airborne — especially on windy days — and may cause symptoms such as sneezing, nasal congestion, and itchy eyes in sensitive individuals.
If you experience allergy symptoms in the spring, coinciding with the cottonwood blooming period, it’s a good idea to test for a cottonwood allergy.
Cottonwood pollen contains proteins that can trigger an immune response in allergic individuals, leading to the typical symptoms of allergic rhinitis.
Limiting outdoor exposure during high pollen times, keeping windows closed, and using air filters can help manage cottonwood allergy symptoms. Consult with a healthcare provider for appropriate allergy medications if needed.
