Sleep is so important and here is just another reason why! Scientists have reason to believe that when we “sleep”, our brain cells shrink in size, thus allowing more cerebral fluid to flush through and wash away build up “toxic” proteins. Why is this only possible when we are in a true state of unconsciousness? The simple answer is, we need all of our brain cells at its tip top shape just to get through our days. Can you imagine what it would be like to function with shrunken brain cells?
