Our Brains Do More Than Dream While Sleeping.
A recent study at NYU has discovered that during sleep our brains may also cleanse itself of toxic molecules. The results showed that during sleep, glymphatic systems may open, letting fluid flow through the brain. Brain cells, called glia cells, were found to control this flow of clear fluid surrounding the brain and spinal cord. These newfound cells could be important for a range of neurodegenerative disorders.
Sleep is more important than we ever thought, it helps clean the brain.
