When we are asleep the brain shrinks slightly to allow the glymphatic system to do its work. The glymphtic system is a system of perivascular tunnels around the blood vessels inside the brain that promotes efficient clearing of soluble proteins and metabolites from the central nervous system. This includes the clearing of Beta amyloid, an increase in Beta amyloid in the brain is linked to the build up of plaque in the brain and can lead to dementia. The brain also needs to be well hydrated in order for the fluid to circulate and 'wash' away the debris and bring fresh oxygen and nutrients.
