This is a seriously eyeopening book. If ever there was a mustread, this is it. | Think 6 hours is enough sleep Think you can power through periods of limited sleep and make it up later Think you’re immune to sleep deprivation because you’re born to hustle Read this book and think again. “Why We Sleep” is highly recommended —> | What were the best books you read in 2017 Very interested in your opinions as I am always looking for good books to read.

Reading Profile
Should I read this?
The book reads like an engaging, urgent lecture from a sleep evangelist, blending accessible science with alarming anecdotes. Its strength is the deep dive into how sleep shapes memory, health, and creativity, making a strong case for its non-negotiable importance. The downside: tone can become preachy and overdrawn, with some claims feeling overstated, leaving you either inspired to protect your slumber or weary of the relentless doom-mongering.
Read this if...
- •A startup founder logging 80-hour weeks who has hit a cognitive wall and wants to understand the biological cost of sleep deprivation, not just generic 'sleep more' advice.
- •A psychology undergrad choosing a research focus who needs an engaging, up-to-date overview of sleep science to spark thesis ideas.
- •A new parent exhausted by conflicting sleep advice, craving a clear explanation of what’s actually happening in their baby’s brain and why sleep regressions occur.
Skip this if...
- •You’ll likely put it down around the middle chapters, when the book becomes repetitive, hammering the same sleep-deprivation risks without offering enough fresh strategies—it drags if you came for practical takeaway beyond 'avoid late-night screens' and 'stick to a schedule.'
- •Not for readers who already know the basics and want novel insights or advanced neurobiology; much of the content covers familiar ground like REM cycles and adenosine buildup, leaving you hungry for deeper mechanisms.
- •Skip it if you prefer scientific caution—the author sometimes presents correlation as causation, which will grate on skeptics and make you distrust the otherwise fascinating narrative.
“Why We Sleep is an important and fascinating book…Walker taught me a lot about this basic activity that every person on Earth needs. I suspect his book will do the same for you.” —Bill Gates A New York Times bestseller and international sensation, this “stimulating and important book” (Financial Times) is a fascinating dive into the purpose and power of slumber. With two appearances on CBS This Morning and Fresh Air's most popular interview of 2017, Matthew Walker has made abundantly clear that sleep is one of the most important but least understood aspects of our life. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such…

Consider The Boy, the Mole, the Fox and the Horse by Charlie Mackesy. Recommended by 8 sources.
“Soft-spoken, heavily illustrated fable built from short dialogues and watercolor sketches.

Most useful when you want quick consolations, a prompt for conversation with a child, or a pause during a rough day. Limiting if you want sustained argument, concrete advice, or tightly plotted storytelling: the repetition of gentleness can feel sentimental or thin after a while.”
