Modern medicine treats chronic cough arising in the workplace with great importance as a manifestation of occupational lung disease. What Donguibogam describes as pathogenic qi takes concrete form in modern society as fine dust, various chemical substances, organic solvents, asbestos, silica, and even the dry, polluted air inside offices. When these hazardous substances are continuously inhaled into our lungs through the respiratory system, they trigger a chronic inflammatory response and can lead to severe lung conditions.
One of the most common occupational lung diseases is occupational asthma. Allergens encountered in specific work environments, such as flour, animal dander, or isocyanates, cause the bronchus to become hyperreactive, leading to cough, shortness of breath, and wheezing. In addition, hypersensitivity pneumonitis occurs when repeated exposure to mold or certain organic dusts inflames the pulmonary alveolus and airway, often accompanied by chronic cough, fever, and chills.
Furthermore, fine dust such as asbestos and silica generated in mining, construction, and manufacturing can cause a serious condition called pneumoconiosis. These dust particles accumulate in lung tissue, triggering inflammation and fibrosis, and ultimately permanently impairing lung function. Even working for long periods in poorly ventilated office environments can irritate the lungs and bronchus through dry, stale air and printer toner dust, provoking chemical bronchitis or nonspecific pulmonary hyperresponsiveness that results in a chronic dry cough.
Such occupational lung diseases are easily mistaken for a simple common cold in their early stages. However, they are characterized by symptoms that ease after work or during weekends and worsen upon returning to the workplace. As the body's immune system continually reacts to hazardous substances, it releases proinflammatory cytokines, which thicken the bronchial wall and increase mucus secretion, trapping the body in a vicious cycle that induces chronic cough. Early diagnosis and protecting oneself from harmful environments are paramount, and one must pay close attention to daily lung health management.
