So now you know, the rest of the story.According to the Verge, a research team working out of the University of Rochester Medical Centre have finally found out the exact reason sleep is so crucial to a healthy lifestyle.
It’s called the glymphatic system, and it acts like a self cleansing mechanism while the body is on shutdown.
Much like how the lymphatic system (named after lymphnotes) rids the body of toxins and waste, the glymphatic system cleanses the brain material of toxins harboring in the gray matter.
Gray matter is what most people think of when their eyes are closed and they’re asked to picture a brain. During sleep, cerebrospinal fluid flows through the passages of the brain that open up while the glymphatic system is operating.
Much like a car wash that uses powerful water hoses to clean the waste off of the vehicles that passes through it, the glymphatic system uses cerebrospinal fluid to clear the waste that has built up in the brain.
While the body is temporarily out of commission overnight, the passages become wider so the glymphatic system can clear more toxins than during the day.
