Allergic rhinitis often appears with vasomotor rhinitis, when the nose is very sensitive to irritants such as cigarette smoke, air pollutants other agents, changes in temperature and humidity, certain foods, medications and emotional stress.

The causes of rhinitisThe cause of the allergic rhinitis is usually pollen, fungi, hair, pet dander, dust. These substances are harmless to most people, but if inhaled allergies they cause exaggerated immune response. This starts a cascade of biochemical reactions, which results in a massive release into the blood histamine and other chemicals that cause inflammation and mucus in the nasal passages and sinuses.

At an open window or door can be hung well moistened sheet or several layers of cheesecloth.
