Hardback. Etat : Like New. Sapiens meets Why We Sleep in an evolutionary romp through the science of sleep--and how we can get better rest--by one of the world's leading sleep scientists. We spend roughly a third of our lives in bed, but for millions of us, not all of that time is spent sleeping. We strive for eight hours per night, only to lie awake thanks to stress, our ever-present devices, a new baby, or that 4pm coffee you thought you needed. As sleep scientist and recovering insomniac Merijn van de Laar shows, the struggle with modern insomnia is nothing new. When homo sapiens evolved hundreds of thousands of years ago, when saber-toothed tigers were their biggest nighttime worry, wakefulness served to protect one's tribe at night. Research shows these episodic sleep patterns even gave our ancestors an evolutionary advantage. We can look to their example for guidance in improving our sleep health and understanding our natural circadian rhythm, too: how our sleep patterns change as we age, the benefits of communal sleep, the importance of environmental factors such as temperature and light. While our myriad gadgets may distinguish us from early humans, understanding the ways our brains evolved to rest can chart the course toward a better night's sleep. Drawing from emerging science, archeological research into our ancestors' habits, and close observation of contemporary hunter-gatherer cultures, How to Sleep Like a Caveman explains everything from why we sometimes jerk awake at night--likely a remnant of having slept in trees--to why our efforts to "optimize" our sleep schedules might just be a fool's errand. The result is a surprising, accessible new framework grounded in ancestral health for thinking about sleep--the way we were designed to.  Drawing on the wisdom of our ancestors, you'll discover: Evolutionary Sleep Science: Why our brains evolved to wake up during the night and how that "episodic sleep" was once a survival advantage against saber-toothed tigers. Beyond the 8-Hour Myth: Learn why trying to "optimize" a perfect eight-hour block of sleep might be a fool's errand and what hunter-gatherer societies teach us about flexible sleep patterns. Primal Sleep Instincts: An explanation for why we sometimes jerk awake as we fall asleep--a fascinating remnant from our tree-sleeping ancestors. A New Framework for Rest: Practical guidance on environmental factors like temperature and light, and how to apply ancestral wisdom to improve your modern-day sleep health.…
