Why Didn’t Ancient Humans Struggle to Sleep?

Why do so many people struggle to sleep today when our prehistoric ancestors survived nights filled with predators, harsh weather, and constant danger? The answer is far more surprising than you might think. In this documentary, we explore the evolutionary origins of human sleep, from our primate ancestors in the trees to the first grass beds built 200,000 years ago. Discover how fire, group living, circadian rhythms, and the "sentinel hypothesis" shaped the way humans sleep—and why waking up in the middle of the night may have once been perfectly normal. Using the latest findings from archaeology, anthropology, and evolutionary psychology, we'll separate scientific evidence from popular myths and reveal what ancient sleep can teach us about insomnia, stress, and modern life. The problem may not be that our ancestors slept better—it may be that they worried about sleep far less than we do. #HumanEvolution #AncientHumans #Sleep #SleepScience #Insomnia #Prehistory #Anthropology #Archaeology #EvolutionaryPsychology #HunterGatherers #History #ScienceDocumentary #DeepEpoch
