If you suffer from hay fever, you are allergic to pollen. Pollen is a fine powder produced by plants such as trees and grass during certain times of the year. Most hay fever patients in the UK are allergic to grass pollen. Most commonly, hay fever symptoms occur in the summer months between May and August. However, some patients experience symptoms as early as January or as late as September.
Being allergic to pollen means that your immune system reacts to pollen as if it were a threat like a germ or a virus. Symptoms can include sneezing, a runny nose and itchy eyes. You may also experience headaches during hay fever season or generally feel tired and unwell.
Hay fever treatments such as tablets and nasal spray reduce the symptoms. They do not cure hay fever and the symptoms will come back as soon as you stop using a hay fever treatment.
