This evolutionary biologist wants you to re-think what 'good' sleep looks like

If you only got a few hours sleep last night and are miraculously functioning today, you have your early human ancestors to thank for that. Sleep has played a crucial role in human evolution, and evolutionary biologist Dr David Samson argues our ability to function on little sleep is actually a superpower. He's spent time observing how humans sleep in "natural environments" — that is, traditional hunter-gatherer societies — and has some insights on how us humans who live in modern, industrial settings can stress less about sleep and feel better rested.
