"The first sleep book by a leading scientific expert--Professor Matthew Walker, Director of UC Berkeley's Sleep and Neuroimaging Lab--reveals his groundbreaking exploration of sleep, explaining how we can harness its transformative power to change our lives for the better. Sleep is one of the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don't sleep. Compared to the other basic drives in life--eating, drinking, and reproducing--the purpose of sleep remained elusive. An explosion of scientific discoveries in the last twenty years has shed new light on this fundamental aspect of our lives. Now, preeminent neuroscientist and sleep expert Matthew Walker gives us a new understanding of the vital importance of sleep and dreaming. Within the brain, sleep enriches our ability to learn, memorize, and make logical decisions. It recalibrates our emotions, restocks our immune system, fine-tunes our metabolism, and regulates our appetite. Dreaming mollifies painful memories and creates a virtual reality space in which the brain melds past and present knowledge to inspire creativity. Walker answers important questions about sleep: how do caffeine and alcohol affect sleep? What really happens during REM sleep? Why do our sleep patterns change across a lifetime? How do common sleep aids affect us and can they do long-term damage? Charting cutting-edge scientific breakthroughs, and synthesizing decades of research and clinical practice, Walker explains how we can harness sleep to improve learning, mood, and energy levels; regulate hormones; prevent cancer, Alzheimer's, and diabetes; slow the effects of aging; increase longevity; enhance the education and lifespan of our children, and boost the efficiency, success, and productivity of our businesses. Clear-eyed, fascinating, and accessible, Why We Sleep is a crucial and illuminating book"--… (lisätietoja)

It's a good reference about the science of sleep: our biological needs, what sleep does to our brain and, most importantly, what are the negative consequences caused by sleep deprivation.
Some things that I learned:
- Sleeping less than 7 hours a night is not enough. We should aim for 8 - 9 hours.
- Sleeping in on weekends doesn't make up for a whole workweek of lack of sleep.
- We should maintain the same sleeping routine throughout the week, including weekends.
- Insomnia in not the same as sleep deprivation.
- It is not recommended to take naps after 3pm.
- A sleep deprived brain has the same decrease in cognitive power than a drunk brain (being sleep deprived is like being drunk).
- Lack of sleep has a huge impact on our health, life expectancy, productivity and learning. ( )

nonfiction/health science.
recommended for fans of Malcolm Gladwell and Steven Levitt, but also anyone who works, goes to school, has kids, drives a car, drinks caffeine or alcohol, has parents, competes in sports, has trouble sleeping, or is concerned about Alzheimer's, mental health, blood pressure, heart disease, cholesterol, or basically any other health issue.
Readers are invited to skip through and just read the parts that interest them (check the index or table of contents), or to read all the way through. Busy people will be happy to know that you can pick this up a few paragraphs at a time, and don't necessarily need long uninterrupted chunks of reading time in order to learn and enjoy. ( )

Simple and powerful insights about the importance of sleep

I came to believe very strongly that use of sleep aids i.e, particularly medications was counterproductive. That is strongly supported by the findings discussed in this book. In addition there is a lot of insight about major social problems aggrevations by inadequate sleep: Alzheimer's, high blood pressure, obesity, depression, automobile accidents. The list is extensive. I worry a little that the author is a bit of a snake oil salesman, giving sleep way to much credit for what it offers our society.. But sometimes the best answers really are simple. He refers to a great deal of scientific evidence.
The author does provide encouraging examples of good results from improving sleep in select groups. If the epidemic of sleep deprivation is half as important as he makes it out to be then it is orders of magnitude more important than Covid for the world's health and well being. ( )

Interesting and thought provoking, though often rather dense, book about the importance of sleep to almost all aspects of physical and mental health and wellbeing. The average number of hours of nightly sleep people get in western industrialised societies has declined markedly over the last century or so. The author is a renowned sleep scientist and this is quite a science-heavy book, with many reports of clinical trials and other research. There are interesting facts about the relative importance of both non-REM (deep) sleep and REM (dreaming) sleep at different stages of life, and how both are vital to cognitive development and health in different ways. The author rues the fact that sleep is not given the same prominence in public health messaging and funding as drink or drugs, when, for example, accidents caused by drowsy drivers are more frequent than those caused by drunk drivers. He makes an excellent case, though I do slightly feel that he interprets every problem through the medium of sleep, in the same way that other writers see every problem as stemming from poor nutrition and/or lack of exercise. As a frequent poor sleeper myself, though, this was a useful read, with a summary of 12 very useful tips at the back of the book. Well worth a look, though most readers will probably not want to wade through all the detail. ( )
