Let’s say I want to maximize the amount of sleep I get, yet still wake up refreshed.
AssUme I wake up before the alarm goes off, I look over at the clock and see I have X minutes left before the alarm sounds.
It seems if X is less than 15 minutes or so and I do go back to sleep, when the alarm sounds I wake up very tired, more so than if I had just gotten up in the first place.
However if X is 40 minutes or so, I seem to wake up ready to go.
I remember reading once (no cite, from a dim memory) that if you take a nap, it should be more than 45 minutes but less than an 1 1/2 hours, due to the phases of sleep or something (hey, I said it was from dim memory).
For what values of X should I just go back to sleep? For what values of X should I roll on out of bed? Assume I can fall back asleep fairly quickly (1-3 minutes).
