While the Donguibogam focuses on lung qi and environmental harmony, modern medicine frames allergic rhinitis as a malfunction of the immune system. The immune system is intended to protect the body against genuine threats, yet in allergic individuals, it mistakenly identifies benign substances such as pollen, house dust mites, and pet dander as dangerous invaders, launching a hypersensitivity reaction.
During this process, the body releases histamine, a key compound behind runny nose, sneezing, nasal congestion, and an itchy throat. Histamine dilates blood vessels in the nasal mucosa to increase watery discharge, stimulates nerve endings to trigger sneezing, and causes tissue swelling that produces nasal congestion. The accompanying throat irritation often stems from post-nasal drip, in which mucus from the nasal cavity and paranasal sinuses trickles down the posterior pharynx. This continuous drainage irritates the mucosal lining, triggering local inflammation, a persistent tickling sensation, and a cough. In some cases, the allergic response triggers a systemic inflammatory response, resulting in noticeable dryness and a foreign body sensation in the throat.
Allergen exposure is rarely isolated. Environmental factors like fine dust, yellow dust, and air pollutants irritate the mucosal lining directly, heightening immune reactivity. Daily lifestyle patterns, including chronic stress and sleep deprivation, disrupt autonomic nervous system regulation and amplify these allergic symptoms. Gut health also plays a substantial role. The gut microbiome houses over 70% of the body's immune cells, serving as a primary site of immunomodulation. When gut microbial health declines, overall immune balance falters, leaving the body more prone to exaggerated allergic reactions.
Allergic rhinitis is thus not an isolated disorder of the nose and throat. It is an interrelated warning sign involving the immune system, the autonomic nervous system, and digestive health. Effective care extends beyond temporary symptom suppression to include comprehensive approaches that re-establish systemic balance and reinforce immune resilience, ultimately protecting daily quality of life.
