What is hay fever?
Allergic rhinitis, also known as hay fever, is a type of inflammation that occurs when your immune system overreacts to allergens in the air*.
The symptoms of hay fever may include sneezing, red and itchy eyes, and an irritable throat. Symptom onset is often within minutes of exposure and can affect sleep, ability to work and concentration.
