The importance of body fluids discussed in Donguibogam shares the same context in modern medicine. What was simply considered 'water' is scientifically shown to be an essential life support system for all cellular functions and skin health.
First, body fluids represent our body’s hydration, which involves complex interactions at the cellular level beyond simply quenching thirst. Each skin cell must retain adequate moisture for metabolism to proceed smoothly, nutrients to be effectively delivered, and waste products to be efficiently eliminated. If the fluid balance inside and outside the cells is disrupted, cellular function declines, directly leading to reduced skin elasticity, dryness, and above all, a dull and lifeless complexion. A sufficiently hydrated environment is also essential for proteins such as collagen and elastin within the skin to function properly.
Second, body fluids are deeply related to microcirculation. Body fluids such as blood and lymph must circulate smoothly for oxygen and nutrients to be sufficiently supplied to skin capillaries. When the autonomic nervous system is excessively activated by stress or fatigue, blood vessels constrict, which can reduce blood flow volume to the skin. During this time, the skin can easily look dull, taking on a bluish or grayish tint. Adequate body fluids lower blood viscosity, improve blood circulation, and play a crucial role in bringing a healthy color and luster to the skin.
Third, oxidative stress and inflammatory response in the skin are also related to body fluids. When body fluids are deficient, cellular defenses weaken, making the skin vulnerable to damage by free radicals, which can lead to hyperpigmentation, skin barrier damage, and chronic low-grade inflammation. Consequently, this can cause an uneven and cloudy skin tone. Sufficient body fluids provide an important buffering effect, regulating oxidative stress and inflammation while protecting skin cells.
Finally, our body’s hormonal balance and detoxification are also heavily influenced by body fluids. Female sex hormones directly affect skin moisture retention and collagen production, while thyroid hormone regulates the metabolic rate of skin cells. An imbalance in body fluids can interfere with the normal secretion and function of these hormones. In addition, sufficient body fluids are essential for liver and kidney detoxification processes. If bodily waste is not eliminated properly and accumulates, it acts as toxins on the skin, potentially causing a dull complexion and breakouts.
Ultimately, from the perspective of modern medicine, the body fluids discussed in Donguibogam can be interpreted as the core vital force of our body encompassing cellular hydration maintenance, efficient blood circulation, oxidative stress defense, hormonal balance, and smooth detoxification. The skin becomes the final outcome and the most honest spokesperson for all these internal processes. Dull skin appearing on the outside is not simply a cosmetic issue, but a clear signal that the balance of body fluids in our body has been disrupted.
