About the book
Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don't sleep. Compared to the other basic drives in life—eating, drinking, and reproducing—the purpose of sleep remained elusive.
Walker answers important questions about sleep:
- How do caffeine and alcohol affect sleep?
- What really happens during REM sleep?
- Why do our sleep patterns change across a lifetime?
- How do common sleep aids affect us and can they do long-term damage?
