Hay fever is an allergy caused by pollen grains released during the pollen season. It’s all about the seasons and the weather! Surprisingly the pollen season can run from February to November.

A single pollen particle can have varying amounts of allergy-causing agents on it. Pollen is like minute microscopic powder grains that float in the atmosphere.

If inhaled, pollen can cause irritation and inflammation. It triggers the antibody immunoglobulin E, which creates mucus and leads to symptoms such as congestion and sneezing.
