What is grass pollen allergy?
Grass pollen allergy is a reaction to tiny grains of pollen released by grasses, which triggers hay fever symptoms in people who are sensitive to it. It mainly happens in the UK from late spring to early autumn, peaking in June and July when grass pollen levels are highest. The body's immune system mistakes the harmless pollen for a threat and overreacts.
Key points:
- Grass pollen allergy causes hay fever, also called seasonal allergic rhinitis.
- It is triggered by pollen from common grasses during warmer months.
- Symptoms appear only when grass pollen is in the air.
