The perspective in Donguibogam remains compelling because it recognized the systemic roots of dizziness centuries ago. Modern clinical understanding explains these liver-related patterns through physiological mechanisms, frequently identifying autonomic nervous system imbalance as a central factor in chronic dizziness.
Operating beneath conscious awareness, the autonomic nervous system regulates functions necessary for life, including heartbeat, respiration, digestion, and blood pressure. It consists of the sympathetic nerve and parasympathetic nerve branches, which function in tandem like an accelerator and a brake. Under sustained stress, the sympathetic nerve becomes excessively active, initiating a tension response marked by increased heart rate, elevated blood pressure, and muscular tightness. When prolonged, the body remains locked in an emergency state, resulting in physiological strain.
Adequate blood supply to the brain is particularly vulnerable during this state. Instability in the autonomic nervous system compromises the regulation of cerebral blood flow. As the stress response prompts vasoconstriction or erratic dilation, blood pressure shifts cause the volume of blood reaching the brain to drop momentarily or fluctuate, triggering dizziness. Much like erratic pressure in a water pipe leads to an uneven flow, blood flow to the brain becomes irregular. The body normally modulates blood pressure to steady cerebral perfusion when standing up quickly, but an exhausted autonomic nervous system loses this fine-tuning capability.
Furthermore, chronic stress continually stimulates the hypothalamic-pituitary-adrenal axis, elevating the release of stress hormones such as cortisol. While helpful in short bursts, sustained cortisol elevation leads to persistent vasoconstriction, inflammatory activity, and decreased immunity, all of which can worsen dizziness.
Conditions like Meniere syndrome are also closely tied to stress. Meniere syndrome involves impaired regulation of lymph fluid in the inner ear. Stress induces vasoconstriction in the microvessels of the inner ear and alters fluid balance, potentially provoking or intensifying episodes. In this context, the classical concept of liver wind serves as an apt parallel to modern neurovascular hypersensitivity and microvascular dysregulation.
Ultimately, dizziness often reflects the systemic impact of stress upon the autonomic and endocrine systems rather than an isolated inner ear or brain defect. Just as Donguibogam utilized acupuncture to promote the circulation of qi and blood and restore internal harmony, modern approaches emphasize steadying autonomic regulation to moderate the stress response. Addressing these underlying regulatory imbalances supports the body's natural restorative capacity over the long term.
