To all my patients struggling through sleepless nights and foggy days, I understand how difficult this experience is. Modern medicine explains the functions of the gallbladder described in the Donguibogam through varied fields, including neurology, endocrinology, and immunology. The Donguibogam's description of the gallbladder as the command center of decisiveness connects remarkably well with the modern concept of the gut-brain axis. Bile acids secreted by the gallbladder do not merely aid fat digestion. Recent research indicates that bile acids influence the gut microbiota, which in turn helps regulate neurotransmitter production in the brain and the stress response. If an issue arises with bile secretion or flow, the gut environment deteriorates, which can negatively affect the production of sleep-regulating hormones such as melatonin.
Chronic sleep deprivation causes sleep debt to accumulate in the brain. The brain uses nighttime sleep to clear metabolic waste accumulated during the day, particularly toxic substances such as beta-amyloid. When sleep is lacking, this clearing process cannot function properly. As a result, brain function declines, impairing concentration, memory, and emotional control. It is much like a computer crashing after running too many programs at once. In particular, frontal lobe function weakens, clouding judgment and increasing impulsivity. Severe daytime fatigue and drowsiness are clear signals that the brain urgently needs rest.
In addition, sleep deprivation increases the secretion of the stress hormone cortisol. When cortisol levels stay chronically elevated, the sympathetic nerve becomes hyperactivated, leading to an autonomic nervous system imbalance that causes palpitations and heightened anxiety. This leads into a vicious cycle that disrupts nighttime sleep again. Decreased immunity is another critical consequence. Immune cells actively work to defend the body during sleep, but insufficient sleep weakens this defense, leaving the body vulnerable to illness. Accumulated daytime fatigue is not just a tired body; it can develop into chronic fatigue syndrome, impacting the entire body through brain hypofunction, hormonal imbalance, and decreased immunity. Listening to the signals sent by the gallbladder and restoring your body and mind through a grounded, scientific approach is essential.
