Runny Nose as Soon as the Air Conditioner Turns On? How to Overcome Vasomotor Rhinitis When Your Nose Is Sensitive to Temperature Changes

Unlike allergic rhinitis, vasomotor rhinitis causes runny nose and nasal congestion symptoms that occur even without specific external antigens. It is a condition where blood vessels largely fail to regulate themselves autonomously, reacting excessively to rapid changes in temperature or humidity. Because blood vessels are densely distributed inside our nose, the mucosa inside the nose contracts or expands in response to temperature changes. During this process, an autonomic nervous system imbalance can trigger nasal congestion and a runny nose. This arises from a combination of stress, fatigue, and environmental factors, and the busy lifestyles and stress of modern individuals can serve as additional factors. In addition, in modern life where air conditioners or heaters are frequently used, dry indoor air and sudden temperature changes can trigger symptoms of vasomotor rhinitis. These environmental factors make the nervous system even more sensitive and lead to excessive reactions in the blood vessels. Maintaining autonomic nervous system balance in daily life helps relieve symptoms, and regulating humidity, regular exercise, and stress management are recommended. Such methods will provide long-term help in alleviating the symptoms of vasomotor rhinitis.
