Qi as Information Flow: A Condensation–Dissipation Framework for Traditional East Asian Medicine

This paper addresses a long-standing translation problem between traditional East Asian medicine and modern physiology: what does Qi mean if it is not treated as a mysterious substance, but as a physically interpretable process?

The paper proposes that Qi can be modeled as biological information flow: the effective capacity of a living system to process, regulate, circulate, and maintain coherent physiological order over time. Under this interpretation, Qi deficiency, Qi stagnation, Blood stasis, acupuncture, breathing, sleep, cardiovascular fitness, and the Seven Emotions are not treated as isolated traditional concepts, but as different manifestations of condensation, dissipation, flow, blockage, and reset in a living information system.

The central contribution is Definition Set 14, which maps key East Asian medical concepts into the Information Physics framework. Qi becomes effective physiological information throughput. Blood becomes the material-metabolic carrier of that flow. Qi stagnation becomes increased dissipation or blocked regulation. Blood stasis becomes impaired material circulation. Acupuncture becomes a topological basis reset that reroutes existing biological energy rather than adding a new substance. The Seven Emotions become mode-specific dissipation channels that can selectively perturb organ-related physiological modes.

The paper develops a three-regime model of health, pre-disease, and disease. In the health regime, recovery and self-reinforcing order dominate dissipation. In the pre-disease regime, recovery and dissipation are nearly balanced, making the system fragile but reversible. In the disease regime, dissipation dominates and the system loses coherent physiological order. This reframes “pre-disease” as a critical thermodynamic boundary rather than a vague traditional category.

The empirical layer is evaluated through an Interpretive Verification Protocol across 23 biomedical and physiological datasets. The paper reports 23/23 consistency across acupuncture EEG entropy, inflammatory biomarkers, vagal slow-breathing effects, default-mode-network changes, glymphatic sleep clearance, sleep-deprivation biomarkers, cardiovascular fitness and EEG entropy, emotion-organ specificity, and cross-traditional flow concepts. These results are presented as retrospective consistency and mechanistic alignment, not as final clinical proof.

Several mechanisms receive special emphasis. Acupuncture is interpreted as a state-reset intervention that reduces dissipation and can shift the system from decline toward recovery. Slow breathing is treated as a dual thermodynamic intervention: it lowers dissipation through vagal regulation while improving systemic throughput through autonomic and circulatory effects. Sleep is modeled as a nightly thermodynamic reset, clearing accumulated waste and preventing entropic drift. Cardiovascular fitness is interpreted as a physical support for lower resting entropy and higher systemic coherence.

The conclusion is that Qi can be made scientifically discussable without dismissing the traditional vocabulary and without mystifying it. The paper does not claim that all traditional medicine is already proven, nor that every classical concept maps perfectly onto one modern variable. It argues that the core clinical grammar of East Asian medicine — flow, blockage, restoration, emotional dissipation, and pre-disease — can be reconstructed as a coherent condensation-dissipation framework within information physics. The paper provides testable predictions and a prediction-data support matrix for future prospective validation.
