This week on The Method Section, Tom takes a look at sleep. Everyone sleeps, everyone needs to sleep... but why? Find out here as we explore what happens when we sleep through the different stages of the sleep cycle, why we actually need to sleep and also the result on the brain and body if we don't get enough sleep. Sleep deprivation is the unseen plague in our society and the effect it could be having on millions, if not billions of people around the world is truly scary.
