Hay fever is a common condition also known as seasonal allergic rhinitis and affects around 1 in 5 people in the UK. It often runs in families and is more likely to affect people who suffer from asthma and eczema.
It is an allergic condition where the body’s immune system overreacts to substances that are usually harmless, for example pollen from grasses, flowers, weeds or trees. The pollen causes the release of a chemical called histamine from cells in the nose, eyes and airways, which cause inflammation. Some people suffer symptoms all year round; they can be allergic to indoor allergens such as house dust mites, pets and indoor moulds. This is called perennial allergic rhinitis.

Hay fever is usually worse between late March and September, especially when it is warm, humid and windy. This is when the pollen count is at its highest.
