Explaining the lung qi of Donguibogam through modern medicine reveals an approach that is remarkably grounded in science. Our respiratory system, including the nose and lungs, serves as the frontline barrier in constant contact with the external environment. The nasal mucosa is lined with cilia and mucus that filter and clear out dust, bacteria, and allergens. This mechanism is known as mucociliary clearance, and it forms an essential component of lung qi.
Chronic allergic rhinitis does not occur simply because the nasal passages are weak. It is an inflammatory disease caused when the immune system mounts an excessive reaction to specific allergens, such as house dust mites or pollen. When allergens reach the nasal mucosa, immune cells, particularly mast cells, interact with IgE antibodies and release inflammatory substances like histamine. This histamine dilates blood vessels and increases mucus secretion, leading directly to nasal congestion, runny nose, and sneezing.
Why do some people remain unaffected while others struggle year-round? Key factors include the autonomic nervous system, the gut-lung axis, and ongoing daily habits. Chronic stress, irregular sleep, and a Westernized diet disturb the balance of the autonomic nervous system. When the sympathetic nerve experiences hyperactivation, blood vessels in the nasal mucosa undergo abnormal cycles of constriction and dilation, worsening edema and triggering excessive mucus. In this sense, the lung qi deficiency described in Donguibogam aligns closely with a disruption in balanced autonomic function.
Recent scientific attention has also focused on the gut-lung axis, showing that intestinal health exerts a strong influence on respiratory wellness. When the gut microbiota becomes imbalanced (dysbiosis), systemic immunity is affected, which can alter the immune response of the respiratory mucosa. Just as the branches—the lungs and nose—weaken when the root—the gut—is unsettled, chronic rhinitis reflects an interconnected challenge involving the immune system, the autonomic nervous system, and daily lifestyle patterns. Shallow sleep, irregular nutrition, and chronic stress gradually erode lung qi over time.
