This accessible book reveals the dangers of sleep deprivation and the benefits of prioritising rest. Discover how this bestseller transformed public understanding and why quality sleep is essential for a vibrant life.


Picture a busy weekday morning. You hit snooze one too many times, gulp down your coffee, and feel the fog of tiredness lingering all day. For many, this is a familiar struggle. Sleep often feels like a luxury rather than a necessity. This is precisely the issue that Matthew Walker, a renowned neuroscientist and sleep expert, tackles head-on in his bestselling book Why We Sleep.

Walker’s credentials are impressive. As a professor of neuroscience and psychology at the University of California, Berkeley, he specialises in the science of sleep and its critical role in human health. Bringing decades of research together, Why We Sleepoffers a compelling and accessible dive into why slumber is far more than just “rest.”

At the heart of the book is a simple yet profound message: sleep is essential to every aspect of life. It shapes how we learn, remember, and make decisions. It influences our immune system, heart health, mental wellbeing, and even longevity. Walker reveals how chronic sleep deprivation is linked to a host of modern illnesses, including Alzheimer’s disease, diabetes, and stroke.

This book also changed how many consider their nightly rest. Walker argues that sleep should be prioritised, advocating for societal changes including later school start times and healthier work patterns. By sharing cutting-edge science alongside gripping anecdotes and clear explanations, Why We Sleep turned sleep from a neglected topic into a daily obsession for readers around the world.

For anyone curious about why their brain feels foggy after a poor night’s sleep or why “catching up” on sleep rarely works, this book provides eye-opening answers. Its influence goes beyond personal habits, stirring public health debates and inspiring new research.
