The Top Ten Sunday Times Best Seller
TLS, Observer, Sunday Times, FT, Guardian, Daily Mail and Evening Standard Books of the Year 2017
Penguin presents the audiobook edition of Why We Sleep by Matthew Walker, read by John Sackville.
Includes a bonus PDF of graphs and diagrams.
Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in twenty-first-century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep.
Until very recently, science had no answer to the question of why we sleep, or what good it served, or why its absence is so damaging to our health. Compared to the other basic drives in life - eating, drinking, and reproducing - the purpose of sleep remained elusive.
Now, in this book, the first of its kind written by a scientific expert, Professor Matthew Walker explores twenty years of cutting-edge research to solve the mystery of why sleep matters. Looking at creatures from across the animal kingdom as well as major human studies, Why We Sleep delves in to everything from what really happens during REM sleep to how caffeine and alcohol affect sleep and why our sleep patterns change across a lifetime, transforming our appreciation of the extraordinary phenomenon that safeguards our existence.

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.

Is Sleep just for the Weak?

A hearty NO! Matthew’s 20+ years of sleep studying and psychological tests have delivered some of the biggest results for humans in the betterment of themselves, their safety and society. This is a must read(or listen) book for all who are interested in prolonging their life or taking steps so as not to shorten it. John narrates the book wonderfully and really brings the enthusiasm that Matthew Walker pens. From increasing you chance of fighting off the common cold to even improving your chances of surviving cancer “Why We Sleep?” is an insightful and motivating book.

If you value your own health, listen to this book.

I was hesitant to purchase this book, as it wasn't something I would normally listen to. However, listening to this book has been one of the most important things i have ever spent my time doing. This book covers the recent and incredibly salient break throughs in the understanding of sleep and the consequences of its neglect. If you value your health/life expectancy or the health of those you care about you must listen to this. My prior attitude towards sleep was reckless. As a student studying maths and physics I regularly sacrificed sleep to complete assignments and other tasks, and in hind sight it's clear how deleterious that behaviour is. Every human should hear this, so their attitude towards sleep recognises/matches its true importance.

Also, fantastically well articulated concepts, by the author, and supurb reading by the reader. (only a few pronunciation mistakes throughout the entire book (impressive!))
