Continuous sleep is a modern habit, not an evolutionary constant, which helps explain why many of us still wake at 3 am and wonder if something's wrong.
This doesn’t mention how long either of the two sleeps were or how long this wakeful period lasted. Can’t imagine it was the same for everyone.
Quite a while back when I had no time schedule pressures, I fell into an sleep wake cycle that was around four hours asleep, followed by eight awake. I found that quite pleasant.
