Reviews and Recommendations

We've comprehensively compiled reviews of Why We Sleep from the world's leading experts.

Bill Gates CEO/MicrosoftExplains how neglecting sleep undercuts your creativity, problem solving, decision-making, learning, memory, heart health, brain health, mental health, emotional well-being, immune system, and even your life span. (Source)

Brad Feld Co-Founder/Foundry GroupSeveral friends, who know I both love to sleep and am intrigued with how sleep works, recommended that I read Why We Sleep: Unlocking the Power of Sleep and Dreams. It was excellent. While my self-assessment of my sleep habits are very positive, I learned a few things. More importantly, I now have a much better understanding of the “Why” surrounding sleep, especially around sleep’s importance to a healthy and long life. (Source)

Alexis Ohanian Sr. Agree! Best book I've read this year. Wasted so many hours just proving to myself I'd be the last one up working at @reddit and for what??? Stupid. Diminishing marginal returns after enough hours without sleep. https://t.co/cT7fDNBF3A (Source)

Shane Parrish A powerful book that's influenced how I think about sleep and my routines. Consider it a compelling case for the superpower that's within reach: sleep. More than other books on the subject that simply focus on the 'what to do', this one gives you why you need to do it. By providing an overview of current sleep knowledge and explaining it in and accessible and detailed way, Matthew Walker sets this book apart from the other books. (Source)

David Heinemeier Hansson Maybe if you weren’t so tired all the time, you’d have time to read a book. I strongly recommend Why We Sleep. The science on sleep is clear: Continuously being deprived will make you miserable and ultimately kill you. Watching the stock market at 6am won’t counter that. (Source)

Bryan Johnson Not only did I become convinced that getting high-quality sleep is the best protector and enhancer of health and cognition, but it is also the most underappreciated. (Source)

Katie Morse @Sinixstar Have you read “why we sleep” yet? Fascinating book and goes into sleep cycles a bit :) (Source)

Ellen Chisa Read the sleep book everyone is talking about (https://t.co/NINYNKy6d9). The most insightful part for me was learning that emotional nightmares are our brain enabling ourselves to internalize the learning from the memory AND reduce the emotional pain we feel over time. (Source)

Preston Pysh @olshansky Great book. (Source)

Trevor Ncube I am almost halfway through reading this book and I am loving it and learning a lot. Based on massive scientific research the book is easy to read and entertaining too. It will be high up there on my 2019 best reads. #TwitterBookClub https://t.co/EpXnCQEcit (Source)

Manu Ginobili I can't recommend "Why We Sleep" by Matthew Walker enough. Amazing book about the crucial importance of sleep in our health. A topic so many times overlooked by everybody (especially by athletes!). (Source)

Joe Kunkle Just an insane amount of awesome studies and detail on how the brain functions in this book... Also, has my mind churning for disruption opportunities to reverse that vicious cycle society has undergone forcing this habit killing people slowly... So much more to learn... (Source)

Adam Johnston The research in Why We Sleep by Matthew Walker has me completely riveted. Unfortunately, it took a Naturopath and many years of burning the candle at both ends for me to realize how important sleep was, not only for my longevity, but for my mood, sharpness, and accessibility to FLOW. Walker states early on in the book that he gives himself a non-negotiable 8-hour block of time for sleep each night. And if a neuroscientist can prove how important something is for my health that I already desire, I’m going to make consistent, sufficient sleep time a higher priority. Spoiler alert: it works.

Barbara Oakley Why We Sleep: Unlocking the Power of Sleep and Dreams is one of the most important books we have ever read. If you read one book to help you with your learning (and life) this year, we think it should be Why We Sleep. It seems that every question we’ve ever wondered about related to sleep is covered by author Matthew Walker’s masterful discussion of sleep. Walker is the Director of UC Berkeley’s Sleep and Neuroimaging Lab, so he knows what he’s talking about when it comes to snoozing. Yet Walker is also a masterful writer, full of witty, insightful metaphors that give an in-depth... (Source)
