Que faisaient vraiment nos ancêtres la nuit ?

What if what you consider a bad night's sleep was actually the normal human rhythm? For thousands of years, our ancestors didn't necessarily sleep eight hours straight. They may have followed a segmented sleep pattern, now largely forgotten. In this video, we explore what might have been happening in the human brain and body when night fell and the world became silent. Before the invention of the light bulb, night wasn't just a time to stop; it held an essential place in human life. What you'll discover: Why the campfire played a major role in the evolution of culture and language. What we call the first and second sleep stages. A frequently cited experiment on ancient sleep patterns. How artificial light and screens have changed our relationship with the night. If you often wake up at 2 a.m. without understanding why, it could be related to old sleep habits, and not just a disorder. Watch until the end to discover what we may have lost by replacing night with the light switch. #History #Sleep #Evolution #Science #Health
