Hay fever help

What causes hay fever?

Despite its common name, hay fever isn't necessarily caused by hay and doesn't result in a fever. It occurs when an allergen that you are sensitive to comes into contact with your nose and/or your eyes1.

So what could these allergens be? They are tiny particles in the air we breathe, like pollen, cat hair or dust, which people may come into contact with every day.1 When a person who suffers from allergic rhinitis comes in contact with an allergen that affects them, the immune system mistakes it for a harmful invader, and prepares itself to fight against it. The immune system then sends in the "soldiers" to fight the allergen - all this extra activity leads to swelling (inflammation) of nasal passages and lots of extra snot.2, 3
