A New York Times bestsellerThe first sleep book by a leading scientific expertProfessor Matthew Walker, Director of UC Berkeleys Sleep and Neuroimaging Labreveals his groundbreaking exploration of sleep, explaining how we can harness its transformative power to change our lives for the better.Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don't sleep. Compared to the other basic drives in lifeeating, drinking, and reproducingthe purpose of sleep remained elusive. An explosion of scientific discoveries in the last twenty years has shed new light on this fundamental aspect of our lives.

Why We Sleep: Unlocking the Power of Sleep and Dreams Reviews

  • Anton

    Great and wonderfully insightful book. Everything you wanted to know about sleep, dreaming and why do we need to do it every night.

    This book will also make your skin crawl sometimes... being part and parcel of the modern sleep deprived culture it is plain scary what the price we are paying for an early morning in the office, or worse an all-nighter power-through.

    This is a great nonfiction and i wish more people will discover this read. 5 ⭐ fair and square

    I thought I was a believer in the importance of sleep. Holy moly, I had no idea. There’s a lot here, and the book is very readable. This will strengthen your resolve if you’re a sleep lover in a world of folks who see a lack of sleep as a badge of pride. And if you think you’ve heard all of the hallow advice about how and why to get enough sleep, the research and advice in this book actually feels fledged out and meaningful.

    For once, I actually mean five stars in the sense of "everybody should read this book." This book is highly readable but contains stunning information I'd never seen anywhere else (and includes numerous references to serious primary literature).

    I was reminded (stay with me here) of ancient Egyptian funerary practices. After carefully embalming organs like the heart and liver, and placing them in canopic jars, the Egyptians pulled the brain out with a hook and threw it away, because they didn't r

    Finally, the book whose author actually said that he will be happy if a reader fell asleep while reading it. Great book!



    I have to admit, I skipped a few chapters due to my incompetence in sleep science. But I am still rating it 5* stars since it was a great and interesting read. In my opinion M.P.Walker said everything about sleep that could be said.

    The thing I liked the most was the style - it had a flowing continuity that was easy to understand for an average reader (I like stuff called popul

    In a nutshell, sleep is even more important than water and food. It is our personal evolution. It is the most effective medicine.

    This book was magnificent. Life changing (my life before I read this book vs my life after I read this book). The last book that created a before/after version of myself was China Study (almost 10 years ago). But unlike China Study, this book read so easily and was fascinating all the way through. This sleep scientist has gift for explaining science using everyday sit

    My favourite book of 2018 so far and one of my all time non-fiction favourites.

    So much in there that just makes sense and explains a lot - wish that I had read this 30 years ago when I started my working life but without giving too much away I shall be making sure that I get my 7 to 8 hours sleep every night (if I do have to work late, I'll make sure that I don't have an early start the next day) , refrain from alcohol just before sleep, avoid looking at my phone in the evening (blue light which

    The less you sleep the shorter your life span will be. Do I have your attention yet? If so read this excerpt from the beginning of this book (p3-5), and you will understand why this book caught my attention.

    This book is divided into four parts. Part 1 defines the nature and types of sleep, describes how the need for sleep changes over a life span, and goes on to discuss the evolutionary origins of sleep. Part 2 describes why you should sleep and lays out the dire consequences of not sleeping.

    "...linking it [lack of sleep] to numerous neurological and psychiatric conditions (e.g. Alzheimer's disease, anxiety, depression, bipolar disorder, suicide, stroke, and chronic pain), and on every physiological system of the body, further contributing to countless disorders and disease (e.g., cancer, diabetes, heart attacks, infertility, weight gain, obesity, and immune deficiency). No facet of the human body is spared the crippling, noxious harm of sleep loss." (p133)
    The book makes a convincing case that:
    "We are … socially, organizationally, economically, physically, behaviorally, nutritionally, linguistically, cognitively, and emotionally dependent upon sleep." (p133)
    I've included the following quotation since it applies to many today who live busy lives, including me somtimes. Researchers have evaluated performance of sleep impaired individuals and have found some sobering facts:
    Most worrying from a societal perspective, were the individuals in the group who obtained six hours of sleep a night, something that may sound similar to many of you. Ten days of six hours of sleep per night was all it took to become as impaired in performance as going without sleep for twenty-four hours straight. (p136)
    Here's another quotation that caught my eye:
    There is no major psychiatric condition in which sleep is normal. This is true of depression, anxiety, post-traumatic stress disorder (PTSD), schizophrenia, and bipolar disorder. (p149)
    Regarding cardiovascular health:
    Adults forty-five years or older who sleep fewer than six hours a night are 200% more likely to have a heart attack or stroke during their lifetime, as compared with those sleeping seven to eight hours a night.(p165)
    Concerned about cancer?
    …the scientific evidence linking sleep disruption and cancer is so damning that the World Health Organization has officially designated nighttime shift work as a "probable carcinogen."(p186)


    Lack of sleep can leave you more prone to Alzheimers disease.

    I heard Walker on NPR and was promptly brought to hysterics over the danger of sleeping too little. I had a techy friend block the wifi on my home router from 8pm until morning, then I bought a data disabling add-on from my phone carrier for my cell phone to lock that too, and I began to measure my smartwatch sleep metrics like workout results; look at me, nine hours! I also procured the book and fell asleep to it quite a few times, which might be a twisted compliment to the author. The other da ...more
