AHS17

We get much less sleep than our ancestors, right? Epidemiology and national polls suggest Americans are getting less sleep than we were 50 to 100 years ago, and therefore, we are likely chronically sleep deprived as a society. But recent investigations into modern-day hunter-gatherer societies suggest natural-living communities don’t get as much sleep as we thought. They don’t go to sleep when the sun goes down and then wake before the sun comes up. Is there something about how they live that reduces their sleep need? What can we learn from them to make our own sleep efficient and effective?
