This is important. I've found that 22.5 x 2^k min for any reasonable k has me waking up feeling refreshed.

- recuter 13y agoWait, what? These numbers seem off.. k = 1 => 45 minutes k = 2 => 1.5 hours k = 3 => 3 hours k = 4 => 6 hours k = 5 => 12 hours
- surement 13y agoThat's exactly it (except that k=5 is not reasonable). The REM periods get longer and longer as you sleep; that is, the "cycles" do not have the same period. Edit: also, k=0 is valid, and what most people have been advocating here (as 20 minutes).
