Hay fever is a common allergic condition that affects up to one-in-five people at some point in their life.
Symptoms of hay fever include:
• sneezing
• a runny nose
• itchy eyes
The symptoms of hay fever are caused when a person has an allergic reaction to pollen.
Pollen is a fine powder released by plants as part of their reproductive cycle. Pollen contains proteins that can cause the nose, eyes, throat and sinuses to become swollen, irritated and inflamed.
