hey guys... i took my first 1.5 hour nap today and learned a few things. first i should probably wear earplugs and fix the lighting in my room because i woke up after about an hour with no REM sleep. then i went back to sleep almost immediately and woke up in the middle of REM. so now i feel groggy. im wondering how youve been waking up from these naps? are your cycles always 90 minutes? because ive been reading that the cycles can be anywhere from 90-120 minutes, where the onset of your first REM is about 90-100 minutes into the cycle. it seems, though, that with deprivation you can get an entire cycle in 90 minutes.
also, most of these websites that are discussing sleep deprivation factor in about 20 minutes of "awake" time as you try to fall asleep. they also have asynchronous timing of the REM portion... so they have REM sleep at around 2:10, 3:50, 5:10 and 6:10 hours after you fall asleep. i assume the theory is that if you deprive yourself of sleep for a while, the cycles will condense themselves down into about a cycle per 1.5 hours. this might be an endorsement of a more "cold turkey" method.
i was wondering what i should do if i find myself waking up again in the middle of a cycle. should i just get up? or let myself go the entire 90 minutes. in hindsight, i probably should have gotten up.
