Hay Fever is a common allergic reaction to pollen that affects up to one in five people. Symptoms include: sneezing, runny nose and itchy eyes. Pollen contains proteins that can cause the nose, eyes, throat and sinuses to become swollen, irritated and inflamed. This is due to the immune system mistaking a substance that is harmless for a harmful one. The body then releases chemicals to fight it. Whilst there's no cure for Hay Fever, the most effective way to reducing symptoms is to avoid exposure to pollen. This can be difficult in summer months when you want to spend time outdoors. Medical treatment options include antihistamines, which can help to prevent the allergic reaction from occurring and corticosteroids, which help to reduce inflammation and swelling. For itchy, swollen eyes, eyedrops can be prescribed from your eye-care professional, however, these should not be used with contact lenses.
