Recent estimates reveal that one in four Britons may have a high risk of suffering from hay fever and thousands of people are making the trip to their nearest chemist for nasal sprays.
Hay fever is caused by the body's immune system mistaking harmless airborne particles as dangerous and releases an antibody, Immunoglobulin E, and an inflammatory substance, histamine, into the bloodstream.
Histamine in the bloodstream is responsible for the hay fever symptoms, such as sneezing, a runny or blocked nose, streaming eyes and itching nose and mouth. Allergy UK's Maureen Jenkins said that one of the best ways to prevent hay fever is to start prophylactic treatment from two to four weeks before pollen appears. "But it's not too late to start now. Using a once-a-day, non-drowsy antihistamine, with a steroid nasal spray to relieve inflammation, is the best therapy", she said.
