Researchers have found that REM (rapid eye movement) sleep is important to human beings. This type of sleep generally occurs four or five times during one night of sleep lasting five minutes to forty minutes for each occurrence(发生). The deeper a person's sleep becomes, the longer the peri...
Sleep is a crucial part of our lives, and rapid - eye movement (REM) sleep is an especially important stage.When we sleep, our brains are far from inactive. During REM sleep, which usually occurs about 90 minutes after we fall asleep, there is increased brain activity. For example, peo...

Rapid eye movement, or REM sleep, is the final phase of the four stage cycle that occurs during sleep. Unlike non-REM sleep, the fourth phase is characterized by an increase in brain activity andautonomic nervous systemfunctions, which are closer to what is seen during the awakened state. ...
