Document Summary

Stage 1: breathing gets gradual, heart rate goes down (nrem1 or. N1): stage between wakefulness and sleep, drowsy sleep. Transition from beta/gamma waves (awake) to slower alpha waves & more rolly (8-13 hz). Kinda awake but going to sleep, muscles are still active (falling off cliff sensation) if someone woke you up at this level, you"d wake up, maybe even deny you"re sleeping. Theta waves (mostly)+ sleep spindles + k complexes. Together keep you out of conscious aware, act as a barrier from outside world. Further away from conscious awareness, more time here than any other stage 45-50% of sleep time, even more if younger. Note that there used to be 2 divisions of stage 3 so there was a stage 4). To do w memory, memory is consolidated and goes into long term memory and if you stay up all night, preventing that from occurring breathing rate, heart rate, etc is at lowest, bedwetting, sleep terrors, sleepwalking.
