Which deficiency type is indicated by feelings of cold?

Feelings of cold are primarily indicative of Yang deficiency. In Traditional Chinese Medicine (TCM), Yang represents the energetic, warming, and activating aspects of the body. When Yang is deficient, the body lacks warmth and energy, leading to sensations of coldness, a tendency to feel cold in the limbs or core, and possible symptoms like fatigue and low vitality.

Unlike Yin deficiency, which is associated with heat sensations and symptoms like night sweats and restlessness, Yang deficiency manifests as cold-related symptoms since it is specifically related to the body's ability to generate warmth and promote metabolism. In this context, identifying Yang deficiency is vital as it informs treatment strategies focusing on warming and tonifying Yang functions to restore balance and alleviate cold sensations.
