"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"--… (altro)

Along with the brain, sleep remains as one of the frontiers of biomedical science. Over a century ago, Sigmund Freud attempted to explore the nature of dreams, but his first attempts seem generally off mark to modern science. Current work has much more evidence to inform it, but few have the time to learn about it. Fortunately, Matthew Walker, a research scientist (notably not a physician), presents a summary of contemporary scientific insights about sleep. He also offers numerous practical applications that can help us all get better quality sleep to live a better quality life.

I have a sleep disability whereby necessary medication causes me to sleep 11-12 hours per night. That change was a tough pill for me to accept, but over two decades later, I have come to accept it as a necessary part of my life. At the same time, I begun to have more vivid dreams. I remain very interested in this topic, and that interest led me to this book. I’m glad I found it.

Walker takes on a variety of topics around sleep and hardly leaves any one untouched. He talks about sleeping pills, dream interpretation, the length of sleep, early waking for schools, and medical residency training, among many others. His reasoning appears balanced and sound. He does not come across as overly preachy, but he does recognize the real, practical, human value of sleep science. He addresses current cultural controversies through science but, as you’d expect from a scientist, does not engage in culture wars.

I’ve learned a thing or two about recent sleep science that will help me along. Most people have a relationship with sleep that’s unique to them, and I suspect most people possess some degree of emotional feelings towards sleep. This book can address both of those life segments in a way that makes their lives better. The author’s words are directed towards a general audience, not just scientists. While heavy on the science, it provides a good reminder that the hours that we’re least active can be the most productive in our lives. ( )

Wirklich interessant! Allerdings nicht ganz einfach zu lesen. ( )

This remarkable book should be on the syllabus of every high school health class on the planet. It never occurred to me how pervasive and easily preventable sleep deprivation could be across our civilization nor how costly it is to our children’s wellbeing and the workplace. The science in this book is stunning. ( )

Read if you want to increase your anxiety about sleep. ( )

Научпоп, компилирующий для обывателя последние достижения ученых, добрался и до жизненно важной и любимой нами сферы — сна. Профессор неврологии и психиатрии из Калифорнийского университета в Беркли смог донести новости науки в удобоваримой форме без формул и непонятных акронимов. Неудивительно, что книга стала бестселлером, тем более что вопрос крайне насущный.

Две трети взрослого населения всех развитых стран недосыпают, а последствия такого тотального недосыпа шокировали сначала ученых, а теперь, по прочтении, потревожат и вас. Всемирная организация здравоохранения вообще официально классифицировала работу в ночную смену как «вероятно канцерогенную». Без нормального сна все попытки сбросить вес тщетны — ни тренировки, ни диета не будут работать, более того, при коротком сне люди употребляют на 300 калорий больше, что в год легко дает 70 000 (с учетом выходных), а это в среднем 5 кг отнюдь не мышц. Тем, кто хвастает на работе, что им достаточно 4–5 часов сна, вы можете только посочувствовать. Это, вероятно, лишь совпадение, но и Рейгана, и Тэтчер, публично заявлявших такое, настиг Альцгеймер. Спать менее шести часов и быть годами работоспособными могут лишь люди с мутацией гена BHLHE41, а таких единицы. С другой стороны, теперь стало понятнее, как именно сон помогает мозгу учиться и закреплять навыки. Быстрый сон (со сновидениями) способствует креативности, демонстрируя смотрящему такие комбинации, которые бодрствующий мозг пресекает в зародыше. А зря, именно так появилась Yesterday «Битлз», а Отто Лёви придумал удостоенный Нобелевской премии эксперимент. Кстати, теперь с помощью сканера ученые могут понимать, что именно вы видите во сне, по крайней мере класс предметов.

Неожиданно, но сновидения, связанные с реально происходящими психологическими травмами — разводом, разрывом отношений, помогают перевернуть тяжелую страницу и войти в жизнь новых эмоций. Те же пациенты, в чьих снах не отражались мучительные переживания, не смогли отрешиться от печального события и оставались в депрессивном состоянии и год спустя. Бывает, что мы спим тревожно не из-за жизненных драм. Часто это происходит в первую ночь на новом месте. Как выяснилось, это разновидность однополушарного сна, существующего в полной мере у некоторых животных. Так, у нас одно полушарие мозга будет спать более чутко, выполняя сторожевую функцию, как, например, у птиц, сидящих в стае с краю. Качеству сна в книге вообще отведена отдельная часть.
