The piece reviews a study which found that during sleep brain cells shrink, thus allowing more space between neurons and giving fluid the chance to wash the brain clean. This cleaning process requires a lot of energy and cannot be done while also processing information, explaining why it happens during sleep. The study also notes that if the toxins are not properly washed away, it may play a role in brain disorders. View the full article here.
