Sleep is the need of life, so people can't live without it. They should make up for the sleep they lack every day, or they will be punished, just like paying off debts.
Scientists divide sleep into two parts: non-rapid eye movement sleep and rapid eye movement sleep. For the convenience of writing, the initials of English abbreviations are capitalized in the literature. Non-REM sleep records NREM, while REM sleep records REM.
The basic law of normal sleep is that normal adults first enter NREM at the beginning of sleep, from shallow to deep, and then turn to REM after about 60 ~ 90 minutes. The duration of REM is only about 10 ~ 15 minutes, and then turn to NREM, so NREM and REM appear alternately periodically, 4 ~ 6 times a night until they wake up.
