Rapid Eye Movement (REM) Sleep By Jane Woo, Sylvia Jung, and Jinsoo Chung.
What is REM? • Rapid Eye Movement • Eyeballs twitch every half minute • Starts after about an hour of falling asleep • Not deep sleep • Dreams happen in this stage • Genitals are aroused during this stage • Your body blocks messages to the brain so you can’t move and you cannot wake up easily • Essentially paralyzed • Muscles are relaxed • “Paradoxical” sleep
Cont’d • 25% of sleep is spent REM • 50% of baby sleep is in REM • It serves to preserve memory, integrate new experiences into your memory, and “to strip new memories of whatever emotional charge they initially carried”. • Dreaming and intelligence is correlated • Handicapped people do not dream as much • People who are depressed go into REM stage faster and stay in it longer; also, REM is more intense.
