Researchers at the University of Rochester Medical Center (URMC) Center for Translational Neuromedicine believe they may have discovered yet another clue as to why sleep is mandatory for good health—especially brain health.
Their report, published in the journal Science,2 reveals that your brain has a unique method of removing toxic waste through what’s been dubbed the glymphatic system.
The clincher is that this system ramps up its activity during sleep, thereby allowing your brain to clear out toxins, including harmful proteins linked to brain disorders such as Alzheimer’s for example.
What’s more, they discovered that your brain cells actually shrink by about 60 percent during sleep, which allows for more efficient waste removal. According to lead author Maiken Nedergaard, M.D., D.M.Sc., featured in the video above:
“This study shows that the brain has different functional states when asleep and when awake. In fact, the restorative nature of sleep appears to be the result of the active clearance of the by-products of neural activity that accumulate during wakefulness.”
