An allergy or allergic reaction happens when your immune system (your body’s natural defence system) overreacts to a normally harmless substance.

These substances are commonly known as allergens and include pollen from grass, trees and flowers, dust mites, pet dander (tiny flakes of animal skin) and mold.

When you come into contact with an allergen, the cells in the lining of your nose, mouth and eyes release a chemical called histamine which triggers an allergic reaction. Typical symptoms of such an allergic reaction include sneezing, a runny or blocked nose and sore, itchy, watery or puffy eyes.

Allergies are very common. They’re thought to affect more than 1 in 4 people in the UK at some point in their lives*. Source :
