About this episode

It’s not news that if you don't get a good nights sleep you will probably not be your best the next day, but while you are snoozing, particularly in deep sleep, your brain is not just powered down, it is busy cleaning out the days toxins, almost like it is ‘washing your brain’ and getting it ready for the next day.   “Sleep is not just a state where things turn off. Sleep is a very active state for the brain – and it seems to be a special state for fluid flow within the brain,” says Laura Lewis, assistant professor of biomedical engineering at Boston University in the Guardian newspaper.  What happens if we don't get enough deep sleep? How can we boost our deep sleep?
