Winter represents the most Yin aspect in Chinese medicine. Yin is the dark, cold, slow, inward energy. This is compared to the Yang of summer whose energy represents light, hot, quick, expansive qualities. The summer weather is warm, the days are longer and people are out being active. In TCM we believe that the diet and activities in winter should be adapted to enriching yin and subduing yang.
Winter, in TCM, is associated with the Kidneys which hold our body’s most basic and fundamental energy. It is believed that by harmonizing oneself with the seasons you can stay healthier and prevent disease, so winter is a good time to strengthen the kidneys.
… The sense organ associated with the kidneys is the ears, and our ability to hear clearly is related to kidney health. The quiet and stillness of winter allows us to hear more of the world than the buzzing activities of summer. This forces us to slow down, rest and relax.
The body part associated with the kidneys are the bones, so it is important to pay close attention to the bones in the winter months making sure to tonify and heal any problems in this area.
