Your brain takes a shower whilst you sleep

This 11 minute TED talk reveals research that shows that when we are asleep our brain (literally) washes away waste products created by metabolising the nutrients brought to it by its blood supply.

One of these waste products is amyloid beta which, if left to build up into plaques, is implicated in the onset of Alzheimer’s.

Another good reason then to make sure you get enough, good quality sleep.
