Before the rise of industry, it was normal for people to sleep in two phases each night.
People had no set bedtimes. Sleeping was determined by whether or not there were things to do. Most people would have a first and second sleep, with a couple of hours awake inbetween. This is probably the way humans are supposed to sleep.
Modern schedules don't really let us do that. Perhaps we should think about changing that.
This is one of my favourite things to tell people about!!
I find lots of people suddenly realise why they keep waking up in the middle of the night when you tell them, too...
Yeah for sure. My grandparents always woke up in the night and went downstairs to do some reading for a bit before heading back up.
Gosh, that really highlights how recent this switch to single phase sleep is!
If you can then why not, amiright?
