Scientists have actually found that the brains activity during sleep, particularly the generation of rhythmic brain waves, is crucial for flushing out waste. During sleep, brain cells produce bursts of electrical pulses that cumulate into rhythmic waves– a sign of heightened brain cell function.But why is the brain active when we are resting?Slow brain waves are associated with restful, refreshing sleep. Without these waves, fresh cerebrospinal fluid could not stream through the silenced brain areas and trapped waste could not leave the brain tissue.Enhancing the Brains Cleaning Process”One of the factors that we sleep is to cleanse the brain,” Kipnis stated.

And now, scientists at Washington University School of Medicine in St. Louis have discovered that brain waves help flush waste out of the brain throughout sleep.”The Mechanism of Brain CleaningBut cleaning up the dense brain is no easy job. Without these waves, fresh cerebrospinal fluid might not stream through the silenced brain regions and trapped waste couldnt leave the brain tissue.Enhancing the Brains Cleaning Process”One of the reasons that we sleep is to cleanse the brain,” Kipnis said.
