The report “Sleep and Health” jointly published by the World Health Organization (WHO) and the World Sleep Research Organization (WFSRS) points out that sleep, like air, food and water, is a basic necessity of human life. According to some statistics, about 35% of people have experienced chronic or periodic sleep disorders, the most common being difficulty in falling asleep; followed by excessive dreaming, waking up easily or not being able to fall back to sleep after waking up, or feeling very light sleep, or even feeling sleepless all night. With the accelerated pace of life, the increasingly intense competition and the increase in life stress, the incidence of this disease is on the rise. According to a global survey in 2002, insomnia as a common physiological and psychological disorder, 43.4% of Chinese people have experienced varying degrees of insomnia in the past year, and 50% to 77% of geriatric inpatients have insomnia. Long-term insomnia can seriously affect normal daytime activities, impair quality of life, and greatly increase the risk of other diseases, making it one of the most difficult to treat diseases of global concern. Traditional Chinese medicine refers to insomnia as “sleeplessness” and “sleeplessness”, which is thought to be caused by the disturbance of the balance of yin and yang in the body due to various reasons, such as the “Treatise on evidence and treatment”, which says: “Yang qi is sleeping automatically and quietly. If the yin qi moves from static to sleep, it is awake; those who do not sleep are sick because yang does not cross yin”. Among them, the operation of Wei Qi and Yin-Yang Stilts are directly related to sleep. Ling Shu – mouth question” cloud: “Wei Qi travels in Yang during the day, and in Yin at midnight. The yin is the main night, the night is the main sleep. … Yang qi is exhausted, Yin qi is strong then eyes closed; Yin qi is exhausted and Yang qi is strong then awake.” Wei Qi travels in Yang then Yang Jing Qi is active. If the spirit moves out of the house, it is awake; if the Wei Qi travels at night in the Yin, the Yin meridian is full of Qi and the main quiet, and if the spirit enters the house, it is asleep. Ling Shu – Cold and Heat Disease” cloud: “Foot Sun has through the Xiang into the brain … into the brain is the difference between Yin Stilt and Yang Stilt, Yin and Yang intersect, Yang into Yin out, Yin and Yang intersect in the eye sharp canthus, Yang Qi is strong then _ eyes, Yin Qi is strong then close eyes.” The Yin stilt vein and Yang stilt vein belong to the eight odd meridians, Yang stilt vein is the difference between the foot solar bladder meridian, Yin stilt vein is the difference between the foot Shao Yin kidney meridian, when the Wei Qi starts to travel from the foot solar bladder meridian to the Yang meridians during the day, Yang stilt vein is gradually flourishing, so the eyes open and cannot sleep; when the Wei Qi starts to travel from the foot Shao Yin kidney meridian to the Yin meridians at night, Yin stilt vein is flourishing, Yang opens and Yin closes, so the eyes close and fall asleep. Therefore, the operation of the Wei Qi and the strength and weakness of the Yin and Yang stilt veins are directly related to sleep and wakefulness. In conclusion, the Nei Jing discusses the pathogenesis of insomnia, which is ultimately an imbalance of yin and yang. Western medical therapies currently used to treat insomnia are generally based on psychotherapy, supplemented by drugs, physical or other therapies. However, because the therapeutic effects of existing methods are often unsatisfactory, coupled with the tendency of drugs to cause side effects such as excessive sedation, tolerance, addiction, neurotoxicity, and depression and aggressive behavior, they often cause additional suffering to patients. Acupuncture therapy has the role of coordinating the overall balance of yin and yang of the body, such as “Ling Shu – root knot” said: “the use of acupuncture, is to know to adjust the yin and yang, adjust the yang and yin, the essence is light, and the shape of the qi, so that the gods within the Tibetan”. This enables the body to achieve “yin and yang secret”, restore its physiological functions, and to a certain extent correct insomnia. Throughout the 20 years of acupuncture treatment literature, we found that the main treatment methods for this disease are “body acupuncture”, “ear acupuncture”, “skin acupuncture” and “head acupuncture”. “head acupuncture” and “plum blossom acupuncture” and so on, and the efficiency of treatment are in 70% to 100%. Among them, body acupuncture is the most commonly used method, mostly to identify the main points. Modern acupuncture experimental research also confirmed: acupuncture can increase the content of inhibitory factors 5-hydroxytryptamine and aminobutyric acid and reduce the content of excitatory factors glutamate in the brain of rats, thus improving the central inhibitory function and thus improving the insomnia state. The human body maintains a relative balance of yin and yang under normal sleep conditions. If there are causes of insomnia at work, such as heart and spleen deficiency, yin deficiency and fire, heart deficiency and timidity, and stomach disharmony, all of them can lead to yin and yang disharmony and insomnia. The key to treating insomnia with acupuncture lies in regulating the bias of yin and yang according to the properties of the symptoms, so that the body can return to “yin and yang secrecy” and restore its normal physiological function. If Yang Qi is strong and Yin Qi is weak, it can lead to insomnia. Conversely, a strong yin qi and a weak yang qi can lead to drowsiness. Both of them can be treated by taking the Zhoghai of the Yin stilt and the Shen vein of the Yin stilt, but insomnia should be treated by tonifying Yin and dipping Yang, while drowsiness should be treated by tonifying Yang and dipping Yin. Acupuncture is free from side effects, addiction, etc. While regulating sleep, it can also play a holistic role in treating other diseases, such as digestive problems, endocrine problems, some gynecological diseases, etc. You will get unexpected gains while treating insomnia. Good sleep quality is a sign of good health.
