Document Summary
A: most likely this person is in stage 4 sleep. But sleep deprivation (48 hours): attention lapse and irritability, but little effect on task performance. Rem deprived subjects show reduced ability to retain new information. Speed of cycling into rem is correlated with a positive mood on the following day. About 15% of adults complain (at some point?) of a sleep disorder. Difficulty in getting to sleep or staying asleep. You sleep 5 hours, but expect to sleep 8 hours like other people. 8 hours is an average --> some people need less, and some people need more. Activation remains high and normal sleep cycle fails to develop. Normal but people with disorder to not start breathing again unless they wake up. People may stop for about 1 minute, hundreds of times in the night--> you will wake up. Sid (sudden infant death syndrome) --> people think this is actually a case of apnea.
