While hearing that your essence is deficient might sound unfamiliar, from a modern medical perspective, it contains remarkably scientific insight. I consider this essence to be the core energy resource overseeing our body's complex neuroendocrine-immune system, much like a company's total assets.
Frequent colds and slow recovery are not simply problems of a few weakened immune cells. When the body undergoes stress, the neuroendocrine system known as the hypothalamic-pituitary-adrenal axis is activated, secreting the stress hormone cortisol. While cortisol regulates the immune response in the short term, sustained high levels due to chronic stress can conversely degrade the function of immune cells and trigger inflammatory responses. The state described in Donguibogam as exhausted essence directly aligns with this adrenal fatigue caused by chronic stress. When adrenal gland function declines, energy production drops, and immunity inevitably weakens alongside it.
Additionally, essence is closely connected to the function of mitochondria, the cellular energy powerhouses. Mitochondria convert the nutrients we consume into energy called adenosine triphosphate, providing the power needed for cellular activities. Immune cells also require vast amounts of adenosine triphosphate for active function. If mitochondrial function declines and energy production does not proceed smoothly, immune cells like T cells and B cells cannot perform properly, ultimately leading to lowered immunity and frequent minor illnesses.
Sleep deprivation is another primary culprit accelerating the depletion of essence. While sleeping, the body undergoes an active regenerative process: repairing damaged cells, secreting growth hormone and immune substances, and detoxifying accumulated fatigue substances. However, if you do not get enough sleep, these regenerative processes cannot take place properly, repeating a vicious cycle of decreased immunity and increased vulnerability to infection. Autonomic nervous system imbalance cannot be overlooked either. When the sympathetic nerve becomes excessively heightened due to stress and overwork, the immune-activating functions handled by the parasympathetic nerve are suppressed, leaving the body far more exposed to illnesses such as colds.
In conclusion, rather than pointing to a specific organ, essence can be understood as an integrative concept of vitality encompassing energy metabolism, hormonal balance, neurological regulation, and the overall immune system. Replenishing and protecting this precious essence is truly the fundamental solution for strengthening immunity and living a healthy life.
