深度睡眠时间长意味着睡眠质量好吗?经常做噩梦是否需要就医?河北王先生仅凭深度睡眠时间长度来衡量睡眠质量的优劣并不科学。深睡眠有利于人体各项生理指标的恢复,但随着年龄的增长,深睡眠时间越来越短,80岁高龄后,深睡眠甚至可以消失,从而影响人体生理和心理的恢复。 Deep sleep for a long time means that the quality of sleep is good? Do you often have nightmares need medical treatment? Wang, Hebei depth sleep alone to measure the quality of the pros and cons of sleep quality is not scientific. Deep sleep is conducive to the recovery of various physiological indicators of the human body, but as the age increases, the deep sleep time is getting shorter and shorter, after the age of 80, deep sleep can even disappear, thus affecting the human body’s physiological and psychological recovery.
