Insomnia is the inability to fall asleep or stay asleep, resulting in sleep deprivation. It is also known as disorders of falling asleep and maintaining sleep (DlMS), which are caused by various reasons such as difficulty falling asleep, short sleep depth or frequency, early awakening and insufficient sleep time or poor quality. The main manifestation is the lack of sleep time and depth, as well as the inability to eliminate fatigue and restore physical strength and energy, the lighter the difficulty in falling asleep, or sleep but not sound, sometimes sleep and wake up, or wake up and can not sleep again, the heavier the sleeplessness all night. Insomnia is one of the common clinical diseases. Although it is not a critical disease, it hinders people’s normal life, work, study and health, and can aggravate or induce palpitation, chest paralysis, vertigo, headache, stroke and other diseases. Stubborn insomnia brings long-term pain to patients, and western medicine treats insomnia mainly by taking barbiturates and benzodiazepines, which do not fundamentally solve the cause of insomnia, but only reduce the excitability of brain cells, thus forcing the brain into a quiet state. By the next day any insomnia continues, so sleeping pills need to be taken for a long time. And long-term use of sleeping pills can form a dependence on sleeping pills or cause medically induced diseases. These are the shortcomings of Western medicine for insomnia. Chinese medicine believes that the main cause of insomnia is due to emotional, dietary internal injuries, after illness and old age, deficiency of endowment, heart deficiency and timidity, which cause the heart and mind to lose nourishment or heart and mind restlessness, thus leading to frequent failure to get normal sleep. Acupuncture treats insomnia mainly by 1: balancing yin and yang: by selecting acupuncture points through dialectical evidence, it can coordinate yin and yang, eliminate the symptoms of heart and spleen deficiency, yin deficiency and fire, heart deficiency and timidity, and stomach disharmony caused by the imbalance of yin and yang, so that the bias of yin and yang can be eliminated and the organism can return to yin and yang secret. 2: Dredge the meridians By seeking the meridian sensation to regulate the balance of the meridians and viscera and blood, eliminating the symptoms of qi and blood disharmony, viscera disorders and meridian blockage, so as to achieve the purpose of improving sleep. 3: Support the righteousness and dispel the evil Through tonifying and dipping techniques to dispel the evil, alleviate the symptoms of disease, eliminate the factors of disease, replenish the qi and blood of the internal organs, enhance the ability to resist disease, so as to achieve the purpose of curing disease. Acupuncture treatment for insomnia is a treatment method to address the root cause of insomnia through individualized treatment plan, which is accepted by more and more patients because of its non-toxic side effects, no addiction and dependence.
