My understanding is that REM sleep is the most important bit of sleep[1], and ever sleep cycle (~1.5 hours) you get more REM sleep than the previous cycle.
While I haven't run the numbers in years, I remember comparing the total amount of REM sleep between someone who slept 7.5 hours (5 cycles) straight vs. someone who slept 9 hours, broken into half (3 cycles and 3 cycles) and finding out that the 7.5 hours got more REM sleep overall.
Granted, this is a very rough calculation based on average numbers of a very simplified explanation, but it would be an interesting issue to research.

- bigchewy 11y agocommon misperception but not true [1]. All phases are important and REM comes last so it's easy to say it's the most important, because it gets cut short most easily. yes, you are right about the increasing amount of REM in each cycle. Overall, if you are relatively healthy, sleep shouild be straightforward - black out your room, eliminate random noise like cats jumping on you and don't turn on an alarm.
