how to sleep

Sleep is a naturally recurring state of mind characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings.[1] It is distinguished from wakefulness by a decreased ability to react to stimuli, but is more easily reversed than the state of hibernation or of being comatose. Mammalian rest takes place in repeating periods, when the system alternates between two remarkably specific methods generally known as non-REM and REM sleep. REM is short for "fast eye movement" but entails a number of other features which include internet paralysis in the system. how to sleep
