Yang Deficiency is an Empty-Cold condition characterized by Coldness and Deficiency. If there is inadequate amount of Yang energy to warm the body or internal Organs, a general hypoactivity of the organic processes occurs and Qi and Blood is more likely to stagnate. Also, Body Fluids can accumulate and congest when Yang is insufficient, resulting in Oedema and puffiness. This pattern differs from Yin Excess because Yang Deficiency also includes Coldness-related symptoms.
Since the root of Yin and Yang ‘resides’ in the Kidneys, if they become impaired from excessive standing, sex, activity or overwork, the weaken Kidney Yang has impacts on the rest of Yang of the body. It creates Spleen or Heart Yang Deficiency. For instance. when Spleen Yang is Deficient, it fails to warm the muscles and to properly metabolize food, resulting in Coldness and Deficient Grain Qi and Blood. A Deficiency of Yang is mostly related to Spleen Yang, Kidney Yang, Heart Yang or Lungs Qi.
Yang Deficiency can be caused by lack of activity or exercise, excessive sex, over-exposure to cold environments and climates, and excessive consumption of cold, raw foods and juices, sweets, alcohol, coffee, iced drinks and frozen foods such as ice cream and frozen yogurt. Congenital defects due to improper care after birth can also cause Yang Deficiency.

Practitioners also learn to read from a long list of seemingly unrelated symptoms. Here patients with Yang Deficiency might experience symptoms like pale face, fear of cold, fatigue and low energy (full list here above).
