八段锦 ——双基线理论的东方实践路径[Baduanjin and the Dual Baseline]

Grounded in the Dual Baseline Theory, this paper argues that the traditional Chinese exercise Baduanjin can elevate dual baseline levels (high dopamine and serotonin baselines), prevent neurodegenerative diseases, and ameliorate chronic conditions. It proposes three parallel pathways: abdominal-pressure-driven cerebrospinal fluid flow, activation of skull-meninges immune channels, and parasympathetic modulation, simultaneously promoting brain physical clearance and neuroplasticity. A meta-analysis of 1,975 participants found that traditional Chinese exercise significantly improved cognitive function in older adults (effect size d=0.83), with Baduanjin showing the largest effect (d=0.85). The authors contend that a morning routine anchored to waking-up through conditioned reflex establishes an automatic signal for daytime cleaning and dual-baseline calibration.

Abstract

Abstract This paper, grounded in the Dual Baseline Theory framework, systematically integrates cutting‑edge evidence on brain waste clearance and neuroimmune pathways, the strategic context of national brain initiatives, and practical designs from behaviorism and hypnotic suggestion. It provides a complete theoretical‑to‑practical argument for Baduanjin as a means to elevate dual baseline levels, prevent neurodegenerative diseases, and ameliorate various chronic conditions. The study identifies that Baduanjin acts through three parallel pathways—abdominal‑pressure‑driven cerebrospinal fluid flow, activation of skull‑meninges immune channels, and parasympathetic modulation—simultaneously promoting brain physical clearance and neuroplasticity. Its morning routine, anchored to waking‑up through conditioned reflex, establishes an automatic signal for daytime cleaning and dual‑baseline calibration. As a low‑risk, high‑adherence non‑pharmacological intervention, Baduanjin offers a daily practicable Eastern practice for brain maintenance.
