You sleep every night. But nobody taught you sleep.
What actually happens inside your brain and body after you close your eyes? Why can short sleep affect performance before you fully notice it? Why do teenagers sleep later? What does caffeine really do? And when is poor sleep more than a lifestyle problem?
Sleep: The Master Switch turns sleep science into a fascinating, accessible journey through the brain, memory, heart, immunity, body clocks, dreams, sleep disorders and everyday performance. Grounded in published research and careful about what science knows, what it only suggests, and what remains uncertain, the book separates evidence from popular sleep mythology.
