Modern medicine provides scientific evidence that deepens our understanding of the wisdom in Donguibogam. Abdominal coldness is not merely a matter of low body temperature; it can be viewed as an aggregate of various warning signs sent by our body's intricate systems. A cold abdomen, identified as a cause of chronic fatigue and lethargy, is deeply linked primarily to the following three systems.
First is autonomic nervous system imbalance. The autonomic nervous system in our body is divided into the sympathetic nerve (tension and activity) and the parasympathetic nerve (relaxation and rest), overseeing involuntary physical functions such as heartbeat, digestion, and thermoregulation. When the sympathetic nerve becomes excessively active due to chronic stress or overwork, our body directs energy toward peripheral blood vessels in preparation for an emergency. Blood flow to the internal organs decreases relatively, which can lead to abdominal cold syndrome. A chilled abdomen disrupts autonomic nervous system balance once again, creating a vicious cycle that worsens circulatory disorder, indigestion, insomnia, and chronic fatigue. It is much like an internal generator losing efficiency from being overloaded.
Second is the disruption of the gut-brain axis. Far beyond a simple digestive organ, the gut possesses an essential neural network that communicates closely with the brain, earning it the name 'second brain'. When the abdomen grows cold, intestinal peristalsis declines, and the balance of microorganisms in the gut microbiome is easily disrupted. This deterioration in intestinal health weakens the intestinal mucosa, potentially inducing leaky gut syndrome, where toxins penetrate into the bloodstream. It also affects the secretion of neurotransmitters produced in the gut, such as serotonin, directly linking to symptoms like low mood, impaired concentration, and chronic fatigue. The signals sent to the brain become unbalanced.
Third is mitochondrial dysfunction. Mitochondria, the factories that produce energy, exist in every cell of our body. In particular, the organs concentrated in the abdomen have vigorous metabolic activity, making the role of mitochondria vital. Abdominal coldness can obstruct efficient cellular energy production by mitochondria. When body temperature drops, enzyme activity falls, cellular metabolism slows down, and the generation of adenosine triphosphate decreases. This becomes a fundamental cause of systemic fatigue and lethargy.
Ultimately, a cold abdomen is an alarm signal that problems are occurring across our body's autonomic nervous system, gut-brain axis, and cellular energy metabolism. Looking through the lens of modern science, we can see that Donguibogam's concept of yang qi is closely connected to thermoregulation, nervous system balance, and cellular energy metabolism. Caring for and keeping the center of our body warm is an essential lifestyle habit that lays the foundation for a healthy life.
