It’s 1/3 of our lives. We get no formal education on sleep and this is a crash course. You'll view and prioritize sleep differently, improving the other 2/3 as well.

Cons: It's incredibly long winded and dry. For every interesting or relevant fact, there’s 8 pages of participant results in various sleep studies to back it up. Despite the author's best efforts to make it easy reading (historical anecdotes and examples in the media), it’s effective at inducing sleep. I’ve been chipping away at this for two months.

There’s a lot to learn here. The history of human and animal adaptation, brain activity during sleep, the benefits of 8hrs, the health risks of less than 8hrs, circadian rhythm change through life, dreams and memory, sleep disorders and drugs, effective nightly routines, and suggested changes to our culture are in here between a lot of tedious and scientific verbiage.

Until there’s a more succinct option, everyone should read this book.
