  • Overview

    We spend around a third of our lives sleeping.

    But how does our body know when to switch off, and what happens during those hours? This book takes you on a fascinating journey through the land of nod and out the other side.

    • What are circadian rhythms and how do they affect our energy levels throughout the day?
    • What are dreams for and how do they happen?
    • What are the different stages of sleep?
    • Do animals experience sleep the same way we do?

    With clear texts and bright, distinctive illustrations, this is a great introduction to a subject that has fascinated us since ancient times and that, in our age of endless stimulation, has never felt so timely.
