Our body is truly like a delicate orchestra. Modern medicine presents interesting scientific evidence explaining why a cold belly described in Donguibogam halts intestinal movement. First, our gut constantly exchanges signals with the brain through a highway known as the gut-brain axis. This is why psychological factors such as stress or anxiety directly affect gut health. Abdominal cold syndrome can be a strong factor that disrupts the balance of this gut-brain axis.
Cold qi affects our body's autonomic nervous system. In particular, it can suppress the activity of the parasympathetic nerve, which regulates intestinal movement, and increase the activity of the sympathetic nerve, which protects our body in threatening situations. When the sympathetic nerve becomes excessively active, intestinal peristalsis is inhibited, digestive enzyme secretion decreases, and intestinal muscles become tense. Just as the body stiffens in a threatening situation, the intestines halt their movement and cannot perform their proper function. This prolongs the transit time of food waste through the intestines, allowing more moisture to be absorbed and creating hard stool, which leads to chronic constipation.
In addition, abdominal cold syndrome affects the blood flow directed toward the intestines. A cold environment constricts blood vessels and can reduce the blood supply to the gut, while blood plays a crucial role in supplying the oxygen and nutrients needed by intestinal cells and in removing waste products. When blood flow is hindered, the vitality of intestinal cells declines and the function of the smooth muscle responsible for contracting and relaxing the intestines weakens, further reducing peristalsis.
Furthermore, our intestines house an ecosystem where countless microorganisms live, known as the microbiome. This microbiome plays a central role in diverse physiological processes throughout our body, including digestion, nutrient absorption, and immunity. When the abdomen turns cold, the balance of the gut microbiota can also be affected, creating an environment where the activity of certain beneficial bacteria is hindered and harmful bacteria easily undergo proliferation. This worsens symptoms such as indigestion, gas, and abdominal distension, acting as a combined factor that ultimately leads to constipation. You should understand this not merely as having a cold belly, but as an important signal that affects our body's core physiological systems as a whole.
