Humans sleep the least of all apes – is it the secret to our success?

Humans have evolved to need less sleep than any other ape, a finding that raises intriguing questions about our evolutionary success. Evolutionary anthropologist David Samson's research suggests this reduced need for sleep may have been a key factor in our species' ability to develop complex societies and advanced technologies. While it seems counterintuitive, getting less sleep might have given our ancestors a survival edge, allowing them to be more alert and responsive. Samson also offers insights into how modern humans can optimize their rest, hinting that better sleep could further enhance our cognitive abilities.
