A scientific paper helped Walker with his research after his failure to determine the differences of brainwave activity between various dementia found in people, with the paper's contents describing the areas of the brain each variant of dementia attacks. It was during his PhD at London's Medical Research Council when Walker learned about how little information there was on sleep. Īn image of Matthew Walker, the author of Why We Sleep.Īt 18 years of age, Walker, who was a medical student at the time, became an "accidental sleep researcher" and moved over to studying neuroscience because of his habit of asking many questions. Walker's communication style, in which he makes use of "metaphors and analogies effectively," allowed him to explain ideas related to sleep in detail. Walker and his team spent roughly 20 years studying the rejuvenating ability sleep has. The book took Walker roughly four and a half years to write. Walker described this encounter as a sincere "independent ratification" that made him write the book. Background Īccording to Walker, who had never written a book at the time, he was motivated to write the book after an encounter with a woman who glanced at his work related to sleep and its benefits for health, stating, "When that comes out, I want to read it". The book has received generally positive reviews from critics, who praised Walker's research and views on the science of sleep, while criticizing the book for its certain claims regarding sleep. Why We Sleep has gone on to become a bestseller under The New York Times and The Sunday Times that discusses the topic of sleep from the viewpoint of neuroscience.

Walker spent four years writing the book, in which he asserts that sleep deprivation is linked to numerous fatal diseases, including dementia. In the book, Walker discusses about the importance of sleeping, the side effects of failing to do so and its impact on society. Why We Sleep: The New Science of Sleep and Dreams (or simply known as Why We Sleep) is a 2017 popular science book about sleep written by Matthew Walker, an English scientist and the director of the Center for Human Sleep Science at the University of California, Berkeley, who specializes in neuroscience and psychology.
