This is very interesting. I have a CPAP machine and it records how many hours a night I sleep. Of the last 5 nights, I slept 7.5 hours 3 times, 9 hours once and 4.5 hours once. All the times I woke up were at the end of 90 minute sleep cycles..... hmmmmm. Even though 4.5 is not ideal, now it makes sense. I noticed in October more than half the days I woke up after a 90 minute sleep cycle. So there is likely something to this
That's excellent, you must be well rested!
