## Description

'Astonishing . . . an amazing book . . . absolutely chocker full of things that we need to know' Chris Evans 'Matthew Walker is probably one of the most influential people on the planet' Evening Standard THE #1 SUNDAY TIMES BESTSELLER TLS, OBSERVER, SUNDAY TIMES, FT, GUARDIAN, DAILY MAIL AND EVENING STANDARD BOOKS OF THE YEAR 2017 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. 'Startling, vital ... a life-raft' Guardian 'A top sleep scientist argues that sleep is more important for our health than diet or exercise' The Times 'Passionate, urgent . . . it had a powerful effect on me' Observer

Review: Review of Why we sleep - A very insightful book on a much overlooked but significant aspect of Human Life. Would recommend it to readers of all age group. The simple narration of difficult areas have made this book highly readable and understandable.
Review: One of the most important books that I've ever read - I can easily say that Why We Sleep by Matthew Walker, a neuroscientist, is one of the most important books that I've ever read. Modern humans have always taken their sleep for granted. It's always something that we can catch up on. And we have been dead wrong about this. Everything in our life is affected by the quality and quantity of our sleep. Almost everything that we do is enhanced/spoiled by our sleeping decision. Humans are not sleeping the way nature intended them to. The number of sleep periods, the duration of sleep, and when sleep occurs has all been distorted by the modern life. Human beings are the only species that deliberately deprive themselves of sleep to their detriment for petty activities. Even moderate reductions for just one week in our sleep disrupts the blood sugar levels so much that we would be classified as pre-diabetic. A few things that stood out for me: • Sleep is divided into non-REM sleep (early night) and REM sleep (mostly later night) • Sleep enhances our capacity to learn, remember and make logical decisions. • It configures our emotions, guards our immune system, takes care of our metabolism and keeps our weight in check. • Its deficiency is the leading cause of road accidents. • “The shorter you sleep, the shorter your life span.” • Inadequate sleep is associated with higher rates of mental disorders, heart diseases, cancer, dementia, etc. • Sleeping pills are no match for natural sleep. • Alcohol is one of the most powerful suppressors of REM sleep that we know of. • Sleep deprivation vastly increases your likelihood of getting infections. • REM sleep is what stands between rationality and insanity. • Many people walk through their lives sleep-deprived and never realize it. • Regularity is the key to good sleep - going to bed at the same time, waking up at the same time no matter what. There is so much in this book which should not be summarized. It has to be read and felt. This incomparable book should be compulsory reading for everyone.

### ⭐⭐⭐⭐ Astonishing and an EYE-OPENER...!
*by P***9 on 12 June 2020*

Mathhew walker, a neuroscientist shows how a good night's shut eye can make us cleverer, attractive, slimmer, healthier, and ward off many diseases like cancer, diabetes, heart attacks etc. Have you slept well last night?? Well if you haven't then certainly you are feeling dizziness while reading this. This book is divided into 4 parts and 16 chapter. I would like to highlight few facts from the book that will surely help you. 1) Every creature on this planet have their on circadian rhythm, a cycle of melatonin. My rhythm is not as same as yours. 2) Not just this one thing, other is 'adenosine' a chemical that builds up in your brain when you're awake. This is also know as sleep pressure. 3) Avoid caffeine in evening as it blocks your sleep pressure. As the caffeine has the average half-life hours of 5 to 7 hours. 4) There are two types of sleep NREM (non- rapid eye movement) and REM (rapid eye movement). The architecture of sleep contains 5 cycles of these two sleeps which occurs alternately. 5) Deep NREM strengthens individual memories and REM sleeps offers fusing and building of information. 6) Our brain is just a memory storage device, with permanent and temporary storages, 7-9 hours of proper sleep required for the transfer of information. 7) The shorter your sleep, the shorter your life. The leading causes of disease and death in developed nations—diseases that are crippling health-care systems, such as heart disease, obesity, dementia, diabetes, and cancer—all have recognized causal links to a lack of sleep. Well, these are the just few. Book contains more astonishing facts with experiments and demonstrations. The book is required to read in perusing manner with pen and paper. It's becomes hard to stay with book after one part as many facts are repeated in later stage of books, but you can skip few chapters. There are very important points of note for individuals, educational institutions, hospitals, organisations and even governments. Besides, what I don't like is that writer just put 12 tips for healthy sleep at the end of book that he should have described in detail rather than irrelevant information. However the book is overall good. If you are in medical or psychology field then you might find it interesting to read. I recommend it to everyone who struggles to sleep at night and also all those who are still don't believe in the benefits of sleep and cutting their sleep hours unnecessarily to get productive. Trust me you can't be productive by skipping your sleep hours. According to author, many scientists and artists got their discoveries and masterpiece in their dreaming state. So what are you waiting for grab this book and just doze off.
