睡眠是一种生理现象,夜间睡眠是一般人生活的基本规律,以往曾认为睡眠是一个被动的平静的过程,是大脑皮质内抑制过程扩散到皮质下而引起.近年来发现人脑也和心、肝、肺、肾等器官一样昼夜不停地工作,睡眠时人脑只是换了一个工作方式,在进行着“重组”和“整顿”而已。实验研究发现睡眠不受大脑皮质直接管辖,脑干有调节与管理睡眠与觉醒的睡眠中枢。总之可以结论,睡眠不是被动过程,而是一种主动过程,它由特定的中枢进行调节,并与某些神经递质的代谢活动有关,睡眠时合成代谢大于分解,有利于精神和体力的恢复及能量的储存,因而适当的睡眠确是最良好的休息,既是维护健康和体力的基础,也是取得高度生
Sleep is a physiological phenomenon, night sleep is the basic law of life, in the past that sleep is a passive calm process is the inhibition of the cerebral cortex spread to the cortex under the caused in recent years, the human brain and heart, The liver, lungs, kidneys and other organs work day and night without interruption. When the brain is sleeping, the human brain only changes one working mode and is undergoing “reorganization” and “reorganization.” Experimental study found that sleep is not directly under the jurisdiction of the cerebral cortex, the brain stem to regulate and manage sleep and awakening of the sleep center. In conclusion, it can be concluded that sleep is not a passive process but rather an active process which is regulated by a specific central nervous system and is related to the metabolic activity of certain neurotransmitters, which is greater than decomposition during sleep, favors mental and physical recovery And energy storage, so proper sleep is indeed the best rest, both to maintain health and physical basis, but also to obtain a high degree of health
