With the change of modern life style and living environment, Yang deficiency insomnia is becoming an important disease threatening human health and should be taken seriously by the whole society. According to the idea of treating the untreated disease, Yang deficiency insomnia can be treated through the three states of “untreated disease”, “desired disease” and “treated disease”, so as to achieve the harmony of yin and yang in the body, the appropriate amount of Ying and Wei, and the Yang energy. The yang energy can enter the yin at night, and the five organs can harmonize with each other, so that the sleep is peaceful and the mind is tranquil. The main manifestation of Yang deficiency insomnia is Yang deficiency, which is characterized by fear of cold, lack of warmth in the hands and feet, preference for hot food, mental discomfort, pale lips and mouth, loose stools, clear and long urine, light and fat tongue with tooth marks and moistened moss, and sunken and sluggish pulse, but no disease has been formed, i.e., the state of “no disease”, which has a certain stage of stability and can develop into disease under the effect of continuous adverse external environmental factors. Under the action of external adverse environmental factors, it can develop into disease. Therefore, it is especially necessary to prevent diseases before they occur, and to treat people who are not yet ill, to harmonize yin and yang, to free their emotions, to live and work normally, to moderate their work and leisure, to maintain health and exercise, to regulate qi and blood, to balance yin and yang, to harmonize qi and blood, to achieve the effect of preventing diseases before they occur. The “Suwen Shanggu Tianzhen Theory” points out that: deficiency of evil and wind, avoid it sometimes, calmness and emptiness, the true qi from it, the spirit within the guard, the disease is safe from, in the “want to disease” stage, Yang deficiency symptoms are more obvious, Yang Qi lifting and lowering imbalance, with mild anxiety, depression and irritability, etc. In the “desire disease” stage, Yang deficiency symptoms are more obvious, Yang Qi is out of balance, with mild anxiety, depression and irritability and other undesirable emotions, a sad face, fatigue, not wanting to speak, thicker clothing, feeling unable to concentrate, dark tongue, white moss, sunken pulse, Yang Qi is the main warming and steaming, Yang Qi is not enough to steam the kidney water to control the heart fire, so that the heart fire on the upper, disturbing the heart and mind, and the appearance of restlessness, irritability, insomnia and dreaminess, and even suddenly mania and other hyperactive symptoms, Yang deficiency is weak, Yang Qi is weak is weak, running powerless, so it is easy to depression. Therefore, it is easy to be depressed, which further affects qi, blood, phlegm, dampness, food and fire, resulting in variable depressive moods. The key to treatment is to channel the bad emotions and establish a good state of mind. “The “LingShu teacher Chuan” pointed out that: ruling the country and the family, there is no reverse and can be ruled, but Shun and carry on the Shun, not only the Yin and Yang pulse on the gas of the reverse and smooth, the people want to follow their will also “will and the spirit is dedicated to straight, the soul is not scattered, regret and anger, the five Tibet is not subject to evil carry on. Control bad emotions, appropriate methods to release psychological pressure, keep a calm mind, the usual regulating the protection of Yang, develop good habits and exercise, to prevent “desire disease” into “has been sick”. At the same time, we need to consolidate the root to support the Yang, can moxibustion acupuncture points, three volt compress and ointment treatment, in order to support the warmth of Yang Qi, to achieve the harmony of Yin and Yang, qi flow, the body is safe. Yang Qi dominates the normal life of a person, the disorder of work and rest, emotional and mental disorders, bad habits make Yang Qi depletion aggravated, can make the already evil “want to disease” stage progress vicious cycle to the “already sick” stage, resulting in the false Yang floating over, Yang does not enter the Yin and the development of insomnia, manifested as It is a type of disease characterized by frequent failure to get normal sleep and can even cause cardiovascular diseases. According to the theory of “the movement of yang begins with warmth” and “the combination of sweet and pungent produces yang”, the treatment of yang deficiency with the method of warming and supporting yang can interrupt the possibility of causing other diseases. The treatment of Yang deficiency is based on the theory of “Yang’s movement begins with warmth” and “Gan and pungency combine to produce Yang”. Weak yang qi, weak kidney qi, deficient yang floating over, resulting in imbalance of qi, unfavorable operation, sleeplessness and restlessness, the method should be to nourish the kidney, warm and submerge the yang qi, you can choose Bengui Tang, Wu Mei Tang, Sihui Gui Gan Longmu Tang or Gui with Li Zhong, Sihui Tang combined with Wu Mei, Cornu Cervi Pantotrichum, Calcined Oyster, etc. to benefit the kidney and submerge the yang, lift up and down, therefore, the study of the specific application of the idea of treating the disease in Yang deficiency insomnia is extremely important to promote people’s physical and mental health and improve the quality of life. Therefore, it is extremely important to study the specific application of the idea of treating Yang deficiency in insomnia to promote people’s physical and mental health and improve their quality of life.
