Пока ты спишь, мозг либо очищается, либо накапливает яд

🧠 In 2012, neuroscientists discovered a system in the brain that had remained elusive for centuries. It operates almost exclusively at night, and it removes from brain tissue precisely those substances whose accumulation is associated with Alzheimer's disease. This system was called the glymphatic system. And since its discovery, a vexing question has arisen. 🔍 A Sanskrit text described its mechanism a thousand years before the advent of the microscope. Not metaphorically—literally. Body position, flow direction, the role of breathing. The vocabulary was different. The mechanism is the same one that is now visible in neuroimaging images. ⚗️ During deep sleep, the intercellular space of the brain expands by approximately sixty percent, and the flow of cerebrospinal fluid accelerates tenfold. This isn't a smooth curve—it's a switch. And how fully it activates each night depends on what happens in the body thirty minutes before sleep. 🌀 This video explains four mechanisms that explain the connection between inversion, breathing, and what the brain does at night. You practice while watching. And you'll learn what happens to this system on the first, third, seventh, fourteenth, and twenty-first days. ⏳ There are things that accumulate. And there are things that stop it. The difference between them isn't a drug or a regimen. It's the physics of body position and the sleep architecture your brain anticipates every night. 📌 This video is for educational purposes only and does not constitute medical advice.
