You’ll be fascinated to learn that our ancestors did sleep, wake up, and then sleep again. A bit like cats, but not all day long, rather overnight.
Long before the Industrial Revolution and the invention of electricity people went “early to bed and early to rise”. And what exactly does that mean? Did they really go to bed early and sleep for hours on end? No.
Our ancestors did not sleep straight through the night, rather they had two nightly sleeps. They would go to bed early and sleep for a few hours, and then they would wake up. Which we modern humans often do, probably our Circadian Rhythms trying to tell us something. So we toss and turn, and feel guilt or anger for not falling back to sleep, they got up and did things, generally quiet things like meditate, pray or read. A few hours later they’d fall back to sleep again for the duration of the night.
Also before the invention of electricity our ancestors slept in complete darkness other than some light from a full moon. There was no light to disturb their sleep or rest. There was no artificial street light or light from electronics to disturb their sleep or rest.
Our cats have their own Circadian Rhythms which are: Sleep. Wake up. Sleep. They do this throughout the day. What’s similar between us and cats is that we aren’t meant to sleep for hours on end.
Doing what you can to flow with human Circadian Rhythm will keep us youthful and disease free. And probably even as agile as a cat.
The article on this link will explain how our ancestors used to sleep. Do read it, it contains a lot of fascinating details about what people did during those wakeful hours at night.
