Respuesta :
In the first part of a night's sleep, NREM sleep is prominent, whereas in the second part of a night's sleep, REM sleep dominates sleep time.
What is sleep?
- Sleep is a naturally occurring state of mind and body that is characterized by altered consciousness, relatively inhibited sensory activity, reduced muscle activity and inhibition of nearly all voluntary muscles during rapid eye movement (REM) sleep, and reduced interactions with the environment.
- Sleep occurs in cycles in which the body alternates between two distinct states: REM sleep and non-REM sleep.
- Although REM stands for "rapid eye movement," this type of sleep has many other characteristics, including virtual body paralysis.
- NREM sleep dominates sleep time in the first half of the night, whereas REM sleep dominates sleep time in the second half of the night.
Therefore, in the first part of a night's sleep, NREM sleep is prominent, whereas, in the second part of a night's sleep, REM sleep dominates sleep time.
