Modern medicine interprets the wisdom of Donguibogam from interesting neurological and endocrinological perspectives. Applying acupressure to Shenmen (HT7) goes beyond merely pressing the skin; it stimulates numerous sensory nerve endings beneath it. This stimulation is transmitted to the brain via afferent nerve fibers, inducing changes in various neurotransmitters.
Particularly noteworthy is the increased secretion of serotonin. Widely known as the 'happiness hormone', serotonin is deeply involved in mood regulation, sleep cycles, and appetite. Stimulation of Shenmen (HT7) influences serotonin-producing regions such as the raphe nuclei of brainstem to promote serotonin release, which can lead to relief from depressive feelings and improvement in sleep quality. It also enhances the activity of gamma-aminobutyric acid, a calming neurotransmitter, helping reduce anxiety and relax the body and mind.
Furthermore, acupressure regulates the activity of the hypothalamic-pituitary-adrenal axis, the central axis of the stress response. Chronic stress excessively activates the hypothalamic-pituitary-adrenal axis, increasing the secretion of stress hormones such as cortisol, which triggers diverse health issues including insomnia, depression, and decreased immunity. Stimulating Shenmen (HT7) soothes this excessive response of the hypothalamic-pituitary-adrenal axis, lowering cortisol levels and helping the body respond to stress more effectively.
It also positively influences autonomic nervous system balance. Under excessive stress, modern individuals often experience sympathetic nerve hyperactivity, easily falling into a fight or flight state. This raises heart rate, elevates blood pressure, and tightens muscles, interfering with deep sleep and amplifying anxiety. Acupressure on Shenmen (HT7) enhances parasympathetic nervous system activity, guiding the body into a rest and digest state that lowers heart rate, relaxes blood vessels, and brings emotional calm.
Additionally, it can improve blood flow to specific brain regions and promote neuroplasticity. Repeated acupressure stimulation helps rewire neural circuits in a positive direction, playing an important role in building resilience against stress and reducing vulnerability to depressive feelings and insomnia. Through these integrative actions, modern scientific mechanisms can clearly explain the effect of stabilizing the heart's spirit described in Donguibogam.
