Neurosis, commonly known as “insomnia”, is very common among middle-aged and elderly people, especially brain workers are more common, hyperbaric neurasthenia has a unique therapeutic effect. 1, the significance of sleep Sleep is an important physiological phenomenon, about one-third of the time in life is spent in sleep, sleep is a kind of protective inhibition, although the loss of temporary time, but gain the next day’s full of energy. In normal people, sleep alternates with wakefulness. Sleep causes physiological changes such as relaxation of muscles, slowing of respiratory heart rate, reduction of oxygen saturation, decrease of basal metabolic rate and reduction of brain activity. External factors, somatic factors, emotional factors, neurological disease factors, etc. can be the cause of insomnia, but most of them are directly or indirectly related to hypoxia. 2.Clinical manifestations Children sleep for a long time because their nervous system is not well developed and their brains are easily fatigued, and the sleep time is gradually shortened with the growth of age. Newborns need 18-20 hours a day, young children need 9-14 hours, young adults need about 8 hours, and the elderly need 5-6 hours. Insomnia is a symptom rather than a disease, with various conditions such as difficulty in falling asleep, early awakening, shallow sleep, and excessive dreaming. Insomnia is generally no obvious change within 2 days, but if there is serious lack of sleep for 3 consecutive days, there will be varying degrees of mental depression, reduced work ability, reduced intelligence (memory, calculation, thinking and judgment), slow reaction, inattentiveness, irritability, easily irritated, etc. For special groups such as “white-collar workers”, due to long-term use of brain For “white-collar” and other special groups, they are in a state of chronic hypoxia due to long-term brain use, and sleep disorders are common, which also verifies the causal relationship between oxygen and insomnia from another perspective. 3, pathogenesis Although there are such and such reasons, the deeper mechanism is mostly related to oxygen deficiency, oxygen is a necessary substance in the metabolic process of the body, energy production, tissue repair, internal and external environmental stability of the body are inseparable from the participation of oxygen, the physiological state of the brain oxygen consumption accounted for 20% of the whole body oxygen, while the weight of the brain only accounts for 2-3% of body weight. If you are a brain worker, the oxygen consumption of the brain is much more than 20%,. Because the brain consumes the most oxygen, so the most sensitive to hypoxia, hypoxia will cause imbalance in the cell membrane sodium-potassium pump long before causing organic diseases, resulting in intracellular edema, mitochondrial swelling, etc. The result directly affects the production of energy, the activity of certain enzymes, people in a slight lack of oxygen when the performance of excitement, increased oxygen consumption in the excited state, in turn, will further aggravate hypoxia, week after week to form a vicious circle, a single rely on It is difficult to get out of the dilemma of neurasthenia or insomnia by single self-regulation measures such as exercise, diet and life rules. 4.Therapeutic mechanism (1) Hyperbaric oxygen can rapidly increase blood oxygen content and improve brain hypoxia: Patients with long-term neurasthenia, as the brain does not get sufficient rest, will inevitably cause further increase in brain oxygen consumption, hyperbaric oxygen can increase the oxygen content in the body by about 10 times, and rapidly improve hypoxia. (2) Hyperbaric oxygen has a regulating effect on the nervous system. (3) Hyperbaric oxygen has a therapeutic effect on certain underlying causes of insomnia. 5.Treatment effect For patients who do not have time to go to the hospital to receive hyperbaric oxygen treatment can also take portable hyperbaric oxygen at home, most patients will get significant improvement or return to normal sleep after 1-2 courses of treatment.
