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.

Informative with passionate narrator

I would recommend this book to anybody who is currently sleeping less than 7 hours per night and wants to find a shortcut to improving their life in all aspects. I found the information here enlightening and the evidence compelling.

The narrator is great too, he manages to imitate the various accents and also reads the sentences in a way that very accurately brings across the weight and meaning of the point that Matthew Walker is trying to bring across. I felt like the narrator was the writer himself.

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.

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.

Facinating and useful

Sorting out my sleep patterns has been my main New Years resolution as I have come to the conclusion that most other things in my life will improve greatly once this is achieved.
But I hadn't realised the vast catalogue of problems sleep deprivation is causing in the developed world. And that almost all of us will be suffering from it to some degree.
This book is both very interesting in explaining the mechanism of sleep, and everything in our modern lives that have an influence on the quality of our sleep.
Concluding with a comprehensive list of everything we can do to free ourselves from the misery of tiredness and under performance in the day and sleeplessness at night.
I'm going to listen again. And this time I'm taking notes.

A life-changing book

Would you consider the audio edition of Why We Sleep to be better than the print version?

The narrator does an excellent job stressing the key phrased and pacing the narration in such a way that I believe I take away more information that I would have if I had read the book myself.

Who was your favorite character and why?

Of course everyone 'knows' that a good night's sleep is important, but my god the author brings together such a body of evidence that I'm left in no doubt of the benefits of 8 hours of natural sleep. You will never take sleep for granted again. I'm convinced that this book will save lives and the health of many people.

What about John Sackville’s performance did you like?

Well paced and a great voice.

Did you have an emotional reaction to this book? Did it make you laugh or cry?

It's more of an intellectual and scientific book, but the importance that sleep plays in our life comes across in a profound way.

Any additional comments?

The author encourages the reader to read/listen to the chapters in the order that appeals to them.

The most fascinating book I have read in 20 years

Would you listen to Why We Sleep again? Why?

Yes, and I am already (immediately after finishing it). The subject has changed my life and I want to ensure I took it all in first time!

Which scene did you most enjoy?

I cannot pick one chapter. They are all exceptional. The beauty of the writing is that you can dip in and out of chapters and read them in any order and they still make perfect sense. Fantastic!

If you made a film of this book, what would be the tag line be?

Sleep: Evolutionary Elixir (SEE for short!)

Any additional comments?

This book has already changed my life and continues to do so. It is no exaggeration to say it is the best book i have ever read/listened to. I am lucky in that I do not particularly suffer from sleep problems but, either way, the book is fascinating, interesting and informative. I could not recommend this book more highly.

Super interesting, lots of sleep science

I found this book really interesting. There's a load of information about how lack of sleep affects your health and performance in all sorts of ways. It made me think about my own sleep habits and some changes I could make to get better sleep.

It's well read and I think the chap's voice suits the content and tone of the book.

Fantastic!

This audiobook has given me a lot of good advice and knowledge on how my daytime habits affect my sleeping habits.
Lots of research and stats, as well as 12 top tips for healthy sleep.
You need to dip in and out rather than listen in one go, but I would certainly recommend Matthew Walker's audio.

Very interesting and possibly life changing book

Would you listen to Why We Sleep again? Why?

The deep and calm voice of the narrator makes this audiobook a pleasure to listen to. I will certainly re-listen to 'Why We Sleep' because it offers plenty of interesting information on the importance of sleep and it's packed with tips on how to make your sleep healthier; to make a full use of the knowledge the book offers, I need to listen to certain chapters again and take some notes.

Any additional comments?

The book is potentially life changing, especially if you happen to suffer from sleep deprivation and/or ill health potentially caused by it. It makes a very strong case for prioritising good sleep and it motivated me to care for myself and my family better. Of particular interest to me were the author's discussions of children's sleep, it's potential connection to ADHD and dangers of sleep deprivation in youngsters. I became a much more sleep-conscious parent as a result. I highly recommend this audiobook!

Any additional comments?

This book has completely changed my attitude to sleep - it presents a number of fascinating facts and new research into the science of sleep and debunks many myths associated with sleep. I was particularly alarmed by the facts associated with sleep and alcohol.

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!))

Amazing book

This book is absolutely fascinating, I always knew sleep was important but until I listened to this I never appreciated how vital it is to every part of our life. I wish Matthew’s recommendations to society were followed in their entirety, what a huge difference it would make to our lives and the lives of our children. I for one will implement as many of his recommendations as I can and for the rest of my life I will prioritize sleep in my life!! Thanks so much for writing this book Matthew!

The most important audio book you will listen to!

If this book doesn't convince you to get 8 hours of quality sleep every night then nothing will. So full of valuable, up to date information about just how influential our sleep really is, on health, well being, productivity etc. The difference between 7 and 8 hours sleep per night was particularly shocking.

Interesting but makes me Sleepy

I love the techanical and scientific reasoning for why we need to sleep such as memory, immunity and healing. The author explains really well why it happens, how it's relevant to the reader and eventually what we can do about it.

I struggled to finish becuase the narrator and how he keeps prouncing 'sleep'. it just triggers an unconscious desire for me to sleep or nap reading it. I wish they didn't use the word so much.

Brilliant account of the science of sleep study

I have never read a book about sleep, though wanted to since I am a poor sleeper. I knew many of the basic problems affecting sleep, but had no idea of the vast amount of information and scientific study devoted to the subject. I feel far better informed now, and know where to turn for more information. In some ways this is a depressing study, since as with weight-loss programs, several favourite activities of mine are best avoided in the interest of better sleep. Matthew Walker presents sleep loss as a major social problem needing to be addressed by governments and big companies - it will take years for all this to happen, but I believe things can improve if we all want it to,
