My Biology teacher told us multiple times that you should sleep in time divisble by 90 minutes and nothing else. Need a nap, don’t bother if you don’t have 90 minutes. Going to sleep regularly, and have to get up at 7? Well if you go to bed at 10 you should set your alarm for 7. Go to bed at 1030, set your alarm for 530.
I can’t remember if it was related to some biological thing she tried to teach us or was just an old wives tale she stood by, but I have followed it ever since. I always feel groggy if I awake at one of the off hours.
The idea is you want that full rem cycle. You’re mildly paralyzed during it and waking out out of sync is a bad time
Average person’s REM cycle varies. Time to sleep varies.
I just did a couple of months worth of nap testing and found when I could and couldn’t get up. And unless the nap was so short that I was still in the state I was in when I passed out, I counted it a success.
