Based on modelling from other #primates, humans *should* #sleep 11½ hours per night. But we’ve evolved to sleep less, and the invention of cooking freed up hours every day that we would’ve otherwise spent chewing. What we do with that time, conversely, affects our quality of sleep.

David Samson, anthropologist: ‘Humans went through a radical evolutionary experiment. We are the primates that sleep the least’
A new book draws on ethnography, neurobiology, and primatology to argue that our reduced sleep is not a byproduct of modern stress, but an evolutionary advantage.
