First and second sleep. Segmented sleep. Bi-phasic sleep. All terms to describe something very few Americans do these days.

Until the end of the nineteenth century, most Americans would divide their sleep into two different intervals, with a 1-3 hour window of activity in between.

A few documented activities included: Sewing, reading, sex, and chopping wood. Using oil lamps and the light of the moon, our ancestors remained engaged throughout between dusk and dawn. I read a story years ago about the perils of traveling between dwellings late at night using these illumination sources. No doubt, giving life to some of our legends of things going bump in the night! All tales are rooted in reality.

    1. I’ve been watching videos on Ted. There is a Sleep Scientist by the name of Matt Walker, and he’s posted some incredible information about sleep. As far as number of hours, eight per night is recommended, but I’m not sure how that plays out with Split Sleep. I’m going to look for an answer to your question. It’s a good question. πŸ™‚
