Who Should Read This Book?

Perfect for anyone curious about human evolution, sleep science, or the intersection of biology and culture. It appeals to popular science readers, anthropology students, and those looking to understand their own sleep habits through an evolutionary lens. Whether you are a sleep researcher or a general reader, The Sleepless Ape offers fresh perspectives.

What Does This Book Explore?

Samson examines the unique sleep patterns of humans compared to our closest relatives, the great apes. He investigates how bipedalism, larger brains, fire, and social structures may have reshaped sleep architecture. The book also looks at modern sleep deprivation's health implications and what we can learn from our evolutionary past. Readers will explore REM sleep, artificial light's impact, and the trade-offs that made us the "sleepless ape."

The Sleepless Ape at a Glance

Why do humans sleep less than other primates? How did our evolutionary history mould our rest patterns? In The Sleepless Ape, David R. Samson delves into these questions, weaving anthropology, neuroscience, and evolutionary biology into a compelling narrative about our most mysterious behaviour.
