Sleep disorders can be caused by a variety of factors and are often associated with somatic disorders, including sleep disorders and allergic sleep. Sleep is closely related to a person’s health. Surveys show that many people suffer from sleep disorders or sleep-related diseases, and the proportion of adults with sleep disorders is as high as 30%. Experts point out that sleep is an extremely important physiological function to maintain human life and is essential for the human body. Chinese medicine has obvious advantages for the treatment of this disease. Etiology Sleep is divided into two periods according to EEG and oculomotor changes, namely non-rapid eye movement period (HREM) and rapid eye movement period (REM). In the non-rapid eye movement period, the muscle tone is reduced, there is no obvious eye movement, and the EEG shows slow and synchronous, and when awakened in this period, sleepiness is felt. In the fast eye movement phase, muscle tone is significantly reduced, rapid horizontal eye movements occur, and the EEG shows a state similar to that of awakening. It has been found that the caudal part of the brainstem has a very important relationship with sleep and is considered to be the location of the sleep center. Various stimulating lesions in this area cause excessive sleep, while destructive lesions cause reduced sleep. It has also been found that central neuromediators are involved in sleep, and stimulation of 5-hydroxytryptaminergic neurons or injection of 5-hydroxytryptophan acid produces non-rapid eye movement phase sleep, while administration of 5-hydroxytryptophan antagonists produces reduced sleep. With norepinephrine antagonists, there is a decrease in REM sleep, whereas administration of norepinephrine agonists produces an increase in REM sleep. Clinical manifestations 1. The abnormal amount of sleep can include two categories: one is the excessive increase in sleep, such as narcolepsy or somnolence caused by various encephalopathies, endocrine disorders, metabolic abnormalities, and episodic sleeping sickness caused by brain lesions, which is manifested by frequent irresistible sleep episodes of short duration (usually less than 15 minutes), often accompanied by symptoms such as falling, sleep paralysis and hallucinations before falling asleep. Another type of insomnia is sleep deprivation, where the whole night sleep time is less than 5 hours, which is manifested by difficulty in falling asleep, light sleep, easy waking or early waking, etc. Insomnia can be caused by external environmental factors (too much light in the room, too much noise around, night shift, car and boat, just arrived in a strange place), physical factors (pain, itching, violent cough, drinking strong tea or coffee before bed, frequent night urination or diarrhea, etc.) or psychological factors (anxiety, fear, excessive thoughts or excitement). Some diseases are also often accompanied by insomnia, such as neurasthenia, anxiety, depression, etc. 2. Episodic abnormalities in sleep refer to some abnormal behaviors in sleep, such as sleepwalking, somnambulism (talking in sleep), night terrors (sudden stirring, screaming, rapid heartbeat, shortness of breath, sweating, disorientation or hallucinations in sleep), nightmares (nightmares), teeth grinding, involuntary laughing, involuntary jumping of muscles or limbs, etc. These episodes of abnormal behavior do not occur during the entire night’s sleep, but mostly during certain periods of sleep. For example, sleepwalking and night terrors, mostly occur in the late stage of orthophasic sleep; while somnambulism is mostly seen in the middle or even the early stage of orthophasic sleep; teeth grinding, involuntary laughing, muscle or limb jumping, etc. are mostly seen in the early stage of orthophasic sleep; and nightmares are mostly seen in the period of heterophasic sleep. In recent years, many doctors from the clinical reality, to explore the mechanism of its occurrence, put forward some new identification ideas. Some scholars believe that the etiology and pathogenesis of insomnia are mainly manifested in the liver, spleen and the five viscera, and the evidence of the five viscera is considered as a whole. They advocate the holistic view of “all the five organs have insomnia”, the treatment system of treating from liver, taking into account other organs and identifying evidence and adding and subtracting, and thus formulated the treatment plan of insomnia by organs. The treatment of insomnia is based on the spirit and emotion, which is closely related to insomnia, so we divide insomnia into worry type, suspicious type, tension type and depression type, and choose the method of clearing heat and fire, draining liver and lowering rebellion, the method of nourishing yin and clearing heat, regulating qi and relieving depression, and the method of clearing heart and tranquilizing mind, harmonizing liver and spleen, etc. We have achieved good results. 3, from the circadian rhythm of the treatment of human sleep is a circadian rhythm of physiological activities, insomnia is the result of this normal sleep-wake rhythm disorder. Following this law, we propose the treatment of insomnia “according to the time and place”. All insomnia is caused by “fire not returning to its roots”, and all treatment plans need to return to the problem of “inducing fire to return to its roots and heart-kidney intercourse”, and insomnia is divided into five types: liver qi stagnation type, kidney essence deficiency type, heart fire It is divided into five types: liver qi stagnation, kidney essence deficiency, heart fire, meridian stasis, and phlegm-damp obstruction. 5, from the liver and spleen on the treatment of insomnia caused by a number of etiological mechanisms are related to the liver and spleen disorders, Chinese medicine treatment of insomnia should be based on the selection of the method of diagnosis and treatment, focusing on the regulation of the liver and spleen. Prevention of sleep disorders is often caused by long-term conflicts of thought or mental overload, mental work, long-term improper handling of work and rest, and weakness after illness. The first thing to do after suffering from this disease is to lift the above-mentioned causes and readjust work and life. Correct understanding of the nature of the disease, the onset of the disease is slowly occurring, the course of the disease is long, often repeated, but the prognosis is good. To relieve yourself of the suspicion that you are “seriously ill”, participate in appropriate physical work and sports.
