Millions of people around the world take some form of sleeping pill to get a good night's sleep. Yet the number of deaths involving sleeping pills has increased dramatically in the last year alone.

While we sleep, the body produces hormones, it grows and repairs itself, and prepares its immune system. Good sleep also protects us from dementia and it is during sleep that our memories are consolidated and catalogued. Sleep is so important that we die of sleep deprivation before starvation. Can we really learn by listening to audiobooks whilst we sleep? How can we prepare ourselves for working a night shift or recover from jetlag? Do teenagers need a lie-in and how useful is a siesta?
