Your Brain Has a “Glymphatic System” That Works Only While You Sleep
Most people know the body has a lymphatic system—but the brain has its own version called the glymphatic system, discovered only about a decade ago.
It acts like a nighttime cleaning crew, flushing out waste proteins linked to Alzheimer’s and other cognitive diseases.
When you’re awake, this system almost completely shuts off.
This means poor sleep doesn’t just make you tired — it literally prevents your brain from taking out its biochemical trash.
