According to The Five Element Theory of Traditional Chinese Medicine, winter is the extreme yin season. Each season has its unique set of qualities and attributes. Winter is associated with the internal organs; the kidneys, bladder, and adrenal glands. The colors are black/blue. The element is water. The sound is chui. Each organ holds emotions. The kidneys have the capacity to hold the spectrum of emotion. An imbalanced kidney or deficient kidney Qi holds fear, depression, paranoia. Balanced kidneys hold wisdom, awareness, and courage.
The practice of qigong in winter helps us fortify our will power and creativity so we can face our fears and raise our spirit.
