TIL for millennia, people slept in two shifts – once in the evening, and once in the morning. Biphasic sleeping is mentioned as early as the 8th Century BC, and appears to have remained the dominant, natural format up until the Industrial Revolution.

I sleep this way.
Kramer did it
I work shift work and sleep like this but people always say its bad. I dont feel bad.
It seems more natural. Our full sleep cycle is only about 5 hours and we all tend to hit that “2 PM funk” at work under the current 7-8 hour monophasic paradigm.
This is in fact a myth. Or speculation at best. We don’t actually have a record of any of this. Only two or three sources can be interpreted like this but none explicitly say this.
Ben Franklin slept in one 7 hour period.
