Two Sleeps

Two Sleeps

In medieval times it was common to have “2” sleeps per night. You would fall asleep for 4 to 5 hours, wake up for 2 hours or so and fall back to sleep for another 3 to 4. It’s been suggested that we may have evolved this way to tend to the fire in order to keep us warm and safe.
