About the Book:
For decades, science couldn't answer a simple question: Why do we sleep?
Matthew Walker spent his career finding the answer.
The truth is staggering.
Sleep is not a luxury. It's not "downtime." It's the single most effective thing you can do to reset your brain and body every day.
Without it, you're not just tired. You're sicker. Dumber. Older. More anxious.
With it? You learn faster, feel better, live longer.
This book doesn't just scare you straight. It gives you a plan.
