Yin means darkness. In darkness, life comes to a rest, a motionless state when body quietly rejuvenates with the nourishment it receives. In health science, yin analogs a decrease in physiological and motor functions for the preservation of energy, organ repair, absorption and storage of nutrition. On the other hand, excessive yin is like a pond in the shade, where dampness and coldness prevail. Excessive inactivity leads to decrease in energy production and accumulation of pathological wastes; such as phlegm, fluid and fat.
