People suffer from various types of allergic problems. There can be many reasons for the formation of an allergy in humans. Allergic rhinitis is a type of reaction that is mainly due to hyperactivity of the human body. When a person inhales something bad, the body’s immune system reacts to a high degree and causes the release of chemicals known to be allergic rhinitis. Grass pollen is the main cause of the formation of allergic rhinitis, also commonly called “hay fever“.
