"8 to 10 hours of reproductive work" Yes, this would tire me out as well. :-) Seriously, I've found that my normal schedule appears to be 7 hours solid, with a 1.5 hr nap, depending. Without an alarm, I wake up 7 hrs later on the dot (and can't get back to sleep), but then require a nap 8 hrs later to make it through the day. I cannot sustain 6 hrs and a 2-3 hr nap for any length of time (maybe a couple of days before I feel like crap). I wonder how many different variations of these kinds of cycles there are among the population and how they vary from the 1st to the 3rd world. |

As for the variations in the sleep cycles, I think it would have to do with the length of time between REM cycles in individuals. I'm sure there's individual variance in both the length of the cycles and how many cycles are needed for "A good night's sleep".
