The Role of Sleep in Alzheimer's Disease

REM sleep is associated with the clearance of toxins that build up across the day. There's some new data to suggest that the slow waves facilitate the clearance of extracellular space, which can lead to something like Alzheimer's disease. Having good sleep that night helps you clear those toxins out so that they are less likely to create and contribute to pathology of the lifespan. Rapid eye movement sleep is your neurons actually change their firing profile and they start to fire faster. This is because the brain is actually slightly more active during this brain stage.
