There is a tune in Huangdi Neijing that says, "The essence of the husband is the essence of the body." So, where does "essence" come from? Chinese medicine says "kidney stores essence" and "waist is the house of kidney". Starting from the waist, exercising the waist every day can tonify the kidney and replenish essence. Exercise the waist more, "kidney essence and strong bones and muscles." Second, regulating qi "Huangdi Neijing" said: "All diseases are born of qi." As for qi, Chinese medicine believes that qi is closely related to liver, spleen and lung. If there is something wrong with qi, it will lead to many problems. When people are old and weak, they are prone to shortness of breath and fatigue, and a series of symptoms such as dizziness, abdominal distension and spontaneous sweating appear. Tracing back to the source, it is all because of stagnation of liver-qi, disharmony between spleen and stomach, and imbalance of lung-qi, which leads to systemic qi disorder. Impatience of temper, insomnia and headache are caused by excessive liver qi; Loss of appetite, shortness of breath and cough are all problems of spleen and lung. It will smooth the regulation of qi movement, relieve the stagnation of liver qi, improve the temper, and change the headache and insomnia; Nourish your vitality, the symptoms of shortness of breath and fatigue will disappear, and your appetite will be good. Huangdi Neijing said that "the heart hides the spirit", and the key to nourishing the spirit is to cultivate the mood. Only when you are in a good mood can you fly high. "The heart governs the blood of the body", and when you are happy, the blood will be smooth. Unrealistic, non-tonic, and unbalanced spirit and spirit are the "three causes" of human diseases-external causes, internal causes, and internal and external causes, which are arranged and combined to produce thousands of intractable diseases. Therefore, it is necessary to cultivate the three treasures of "essence" and prevent diseases from taking advantage of it, so as to achieve the health of the five internal organs containing essence and fundamentally eliminate the "three major causes" caused by the imbalance of essence and qi.
