Sleepfaring

Why do we sleep? How much sleep do we normally need, and what happens if you don't get enough of it? Jim Horne finds the answers to these questions and many more in Sleepfaring, a journey through the science and the secrets of sleep. He reveals what goes on in our brains behind the veil of sleep, looks at body clocks and sleeping patterns, the values of napping, and the controversial question of 'sleep debt', and also gives some hints from the latest sleep research that may just help you get a better night's rest.
