Tired No Matter What You Do? A Hidden Circulation Issue Might Be the Cause

Centuries after Donguibogam was written, its observations remain compelling from a modern medical perspective. The persistent exhaustion we experience as chronic fatigue actually stems from complex interactions among several bodily systems, with blood circulation playing a central role. What Donguibogam describes as the flow of blood corresponds in modern physiology to the vital process of delivering nutrients and oxygen to every cell while removing metabolic waste. Recent research on conditions such as chronic fatigue syndrome and myalgic encephalomyelitis shows that circulatory insufficiency impairs cellular energy production well beyond ordinary tiredness. Mitochondria, the cellular powerhouses, require an adequate supply of oxygen and nutrients to function. When circulation is compromised, this supply declines, reducing the efficient production of adenosine triphosphate, the body's primary energy currency. It is similar to a power plant facing fuel disruptions, leading to inconsistent power output. Poor circulation also allows inflammatory markers and metabolic waste to build up in tissues rather than being cleared efficiently. This can create a chronic inflammatory state that worsens muscle pain, joint pain, and generalized lethargy. Brain function is equally vulnerable. The brain consumes roughly 20% of the body's total oxygen supply. When blood flow is hindered, the reduced delivery of oxygen and glucose can trigger cognitive issues commonly called brain fog, such as impaired concentration, memory impairment, and slower processing. This closely mirrors the Donguibogam description of the spirit not being at ease. Furthermore, circulation closely interacts with the autonomic nervous system and endocrine system. Under stress, blood shifts predominantly toward the heart and major muscles, reducing flow to the digestive system and peripheral blood vessels, which can lead to cold extremities or indigestion. This imbalance can disrupt cortisol rhythms, interfere with restorative sleep, and reinforce a cycle of worsening circulation. Because the body operates as an integrated system, hypofunction in one area can contribute to systemic fatigue. Listening to your body means paying attention to the circulation operating deep within.
