Why Do We Sleep?
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.
