What if humans never slept? In this video, we explore what science says would really happen if humans stopped sleeping completely. From brain failure and memory loss to hallucinations and micro-sleep, scientists already understand why sleep is essential for survival. Sleep is not just rest. While you sleep, your brain repairs itself, removes toxic waste, and regulates emotions. Without sleep, the brain slowly begins to shut down. In this video, you will learn: • What happens to the brain without sleep • How long humans can stay awake • Why hallucinations begin after sleep deprivation • What micro-sleep is and why it’s dangerous • Why humans cannot survive without sleep This video is for educational purposes and explains science in a simple and visual way.
