Sleepfaring

Why do we sleep? How much sleep do we normally need, and what happens if you don't get enough? Jim Horne gives an engaging account of what science has found out about sleep. He brings in brain physiology, psychology, medicine, and social factors, and does not shy away from controversy such as research on the amount of sleep we actually need. As well as being richly informative about the nature of sleep, this book may just help you to get a good night's rest.
