Chinese medicine believes that the four seasons health care should follow the principles of spring, summer, long autumn harvest and winter storage. In winter, the human body should recharge its batteries and recuperate, so as to facilitate the contribution and harvest of the spring, summer and autumn harvest in the coming year. The winter climate is cold and dry, and the joints of limbs are stiff. The yang of the human body is also in the adduction stage, and its metabolism is relatively slow. Therefore, the key to health care in winter lies in "hiding", lying early and getting up late, warming up when the cold goes away, and hurting the kidney when it goes against. Winter yoga practice should also follow this principle. Do more warm-up exercises before practice, do less or no difficult postures, do more small joint movements, such as finger, wrist, toe and ankle exercises of expelling wind series, do more Japanese worship, and do more simple yoga postures within your power. Wait until spring to improve yourself.
