CORE DEFINITION

Extreme heat generates cold. When high fever (extreme Yang) reaches its peak, symptoms of cold (Yin) such as cold limbs and faint pulse may appear instead. This is deep heat causing deep cold.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Physical phase transition. When water is heated to thousands of degrees, it may become plasma (properties change). Seeing a high-fever patient suddenly develop cold hands and feet should not be mistaken for cold invasion; it is heat trapped inside unable to escape (extreme stagnation), requiring heat dispersal, not warming Yang.

anchor

Anchor fast decisions

The law of mutual transformation of Yin and Yang: when Yang reaches its extreme, it transforms into Yin ('Extreme Yin turns Yang, Extreme Yang turns Yin'), reflecting the tendency of things to transform into their opposites at the extreme.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

In syndrome differentiation and health preservation, be wary of 'overdoing it' and decline after peak. Use it to explain transitions such as high fever turning into cold extremities. In strategy, prevent overexpansion from backfiring.
