What sleep can do for you and what sleep deprivation does to you. I doubt you can grasp the entire picture since sleeping less impacts you greatly but simultaniously prevents you from seeing it for yourself. This book has my believe reinforced that sleep is one of the most important things in life. If i can live 10 years longer and experience family in that time by just sleeping an hour longer i'd accept that trade any day. If you use alarm clocks during the week the book is essential for you. If you lie in bed and scroll through your phone or even have a tv in the bedroom this is for you. Do you spent hours on end in the evening prolonging the inevitable sleep just to wake up tired and regret not going earlier? This is for you. I take naps since school. They were essential for me. I embraced them during uni and aced many exams with naps in my repertoir. I feel refreshed when i can take a nap during my workday and hate it when i can't in the office. If you think sleep is just something we need to do and deserves to be cut short this book (and I) will gladly prove you wrong on every conceivable level.

The book offered me new perspectives regarding better sleeping and how I can personally improve my sleep quality. But this is book isn't a "sleep-help-book" but rather offers a lot of information regarding what happens in the body during sleep, what are the different sleep stages and how they affect overall health. The author also writes about how modern medicine copes with sleeping disorders and what can be improved in the 21st century regarding sleep quality.

Do yourself a favour and read this book! This book really deserves 5 stars. We all sleep yet few of us know why we do it and what function it serves. This book takes the reader onto a journey through the science behind sleep and uncovers in a very understandable way which systems are at play. It draws a clear picture of what a lack of sleep does to sleeping creatures and why most of us should change the way we approach sleep. This is all done in a wonderfully concise, scientifically accurate and humerous manner. The author gives valuable advise and solution strategies to overcome the "world wide sleep deprivation epidemic". I really like books that deconstruct the seemingly mundane things. Things we just do without wondering why. Good read!

I consider this book a must-read. It is written by one of the world's leading sleep scientists and explains the fascinating sience of sleep. But the true value of this book lies not in the information you gain from reading it - which are important as well though - but rather in the increased appreciation for sleep every reader probably experiences. So if you sleep just twenty minutes longer because you read this book, it was well worth the money and time you invested in it. Why? Just read!

This book has undoubtedly changed my life. Sleep is as important as diet and exercise for your health, yet terribly neglected. I loved how Matthew Walker stressed the importance of sleep and the ways society could change to help get more of it. On the other hand, some of the reasoning was weirdly economical. I hated the bit where it was suggested people should sleep more to be more efficient at work and make the economy grow. I also had a good portion of deja-vu throughout… this is partly due to studies discussed having similar findings, but also partly due to structure. A good chunk in the middle was quite hard to get through without thinking… haven’t I read this before…? Perhaps this will help engraving the knowledge into my brain.
