The Cold-Induced Dry Cough Algorithm (風寒乾咳演算法)

Published: 2026-10-20 // Vector Analysis & Jing Fang

1. The Macro-Vector & Host Environment

When ambient autumn temperatures drop while commercial air-conditioning remains locked at 19°C, stepping from a heated street into an indoor cold blast causes an instantaneous contraction of the superficial Taiyang (太陽) layer. The pathogen is not an isolated microbial anomaly; it is cold air paralyzing the local micro-circulation of the upper respiratory tract.

2. Cryptographic Formula Architecture

Commercial suppressants sedate the nerve reflex ("closing the door on the robber"). The classical Shanghan Lun (傷寒論) algorithm does the exact opposite: it opens the surface, warms the core, and steams fluids upward.
