Though we do it for hours every night, sleep is not well understood. One thing we do know: sleep is crucial for our health and happiness. Snoozefest is a highly readable and fascinating look at why sleep is so important, what's happening in our bodies while we're snoozing (it's a lot more than you think!), and how the science of sleep research has evolved. It probes some of the mysteries, like why we need sleep, why we dream, and even how long we can go without shut-eye! It also explains why teens and tweens aren't getting enough sleep — and what school principals can do about it. This is a deep dive into an intriguing topic, and the book is anything but a snore!
