Examining the Donguibogam concept of consumptive disease through the lens of modern medicine reveals clear parallels. Daily throbbing headaches, eye fatigue, shoulder stiffness, and impaired concentration are not merely isolated symptoms; they can be key expressions of the chronic stress response and brain fatigue syndrome commonly seen today.
Persistent stress excessively activates the sympathetic nervous system, which governs our body's fight-or-flight response. When the sympathetic nerve becomes hyperactive, muscles tense up, blood vessels constrict, and heart rate and blood pressure rise. In particular, the muscles around the scalp, neck, and shoulders, known as pericranial muscles, chronically contract, and this muscular tension is the primary cause of tension headache. It is characterized by pain that feels as if a tight band is pressing down on the entire head. Furthermore, tensed neck and shoulder muscles impede blood circulation and compress nerves, creating a vicious cycle that worsens the pain even further.
When modern eye fatigue is added to this, the situation becomes even more complicated. Excessive exposure to smartphone and computer screens reduces blinking frequency, stiffens the muscles around the eyes, and worsens dry eye syndrome. This digital eye strain goes beyond visual fatigue to induce tension in the muscles around the cervical vertebrae, serving as a direct link back to tension headache.
Furthermore, chronic stress and fatigue can alter our brain's pain perception system itself. This is called central sensitization, a phenomenon where the brain is reset to react hypersensitively even to minor stimuli. It is similar to an alarm becoming so sensitive that it sounds at the slightest vibration. Mild stimuli that were originally not perceived as pain come to be felt as painful, and the pain may last longer and feel more intense.
The hypothalamic-pituitary-adrenal axis, which regulates our body's stress response, is also disrupted in a state of chronic fatigue. If this axis remains overloaded, abnormalities arise in the secretion of the stress hormone cortisol, leading to sleep disorder, decreased immunity, mood changes, and a lowered pain threshold. Ultimately, the body falls into a vicious cycle of continuous exhaustion and heightened pain perception. Impaired concentration is also deeply linked to frontal lobe hypofunction. Chronic brain fatigue and stress upset the balance of neurotransmitters needed for cognitive function, such as dopamine and norepinephrine, markedly lowering concentration during learning or work.
In the end, what Donguibogam calls consumptive disease is very closely connected to what modern medicine explains as chronic stress, tension headache, brain fatigue, and the resulting imbalance of the nervous system. Our body functions as an interconnected organism, so when one part tires, it inevitably affects the entire system. Therefore, it is helpful to understand that the headache you are experiencing is not just a problem of the head, but an earnest signal from your entire body asking for rest.
