Why can some birds sleep with only half of their brain? What really happens during REM sleep? Why do our sleep patterns change across a lifetime? Sleep is one of the most important but least understood aspects of our life, health and longevity. Until very recently, science had no answer to the question of why we sleep or what good it serves or why we suffer such devastating health consequences when it is absent. In this book, neuroscientist and sleep expert Matthew Walker charts 20 years of cutting-edge research.

Ground-breaking, so the flaws are forgivable

Potentially life changing, which you cannot say about many books. The science is illuminating and the evidence is extremely persuasive.

It is not without flaws. The futurology and social commentary is less convincing. If you spend much of a book setting out the facts, supported by evidence, in order to build an argument that is not widely understood, you endanger your overall message if you veer off into ideas and opinions. In that regard it also felt padded a little.

The narration is very good, if a little "high and mighty" in its tone.

But pay little attention to these flaws. The core of this book is truly profound, and may cause you to rethink how you live your life.

And if you want an executive summary: Get another 30-60 mins sleep per night. You won't regret it.
