Conventional wisdom tells us that we should get at least eight hours of sleep a night, but a recent report by the BBC suggests that this might just be a myth.

Historian Roger Ekirch believes that in the past, it was normal to get two sleep sessions, one early evening, a break, and then a second later at night.

The report cites historical evidence that seems to prove this pattern; neighbors visited between sleeps and doctors advised that conception of a child is best between sleep sessions.
