Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in twenty-first-century society, with devastating consequences: every major disease in the developed world – Alzheimer’s, cancer, obesity, diabetes – has very strong causal links to deficient sleep.
In this book, the first of its kind written by a scientific expert, Professor Matthew Walker explores twenty years of cutting-edge research to solve the mystery of why sleep matters. Looking at creatures from across the animal kingdom as well as major human studies, Why We Sleep delves into everything from what really happens during REM sleep to how caffeine and alcohol affect sleep and why our sleep patterns change across a lifetime, transforming our appreciation of the extraordinary phenomenon that safeguards our existence.
I have suffered from poor sleep on and off for most of my adult life. I’ve tried all the usual things – less caffeine, less alcohol, more alcohol, warm baths, no screen time after 8 p.m. – the list goes on and on and none of those things have worked. So I was keen to read this book and see if it could offer any help.
It does so much more than that. This book goes into real depth about how and why we sleep. It’s scientific, research-based and full of sometimes quite startling information. But it does all this in a very readable and reader-friendly way. It isn’t confusing or dense, and it certainly isn’t boring. It’s informative and fascinating and very, very well-written.
It’s eye-opening and concerning to discover just how much of an impact on health – both mental and physical – poor sleep has. And it’s a real concern in a culture that is based on work, work, work with little time for relaxation. It’s a reminder that sleeping and resting and caring for yourself isn’t a luxury or an indulgence but is something that is vital and necessary. A real wake-up call.
I still don’t sleep all that well, but I have more good nights than bad. And I understand now how important that is.
I can’t recommend this book enough.
