Summary
Walker’s book, 'Why We Sleep', is structured around the concept that sleep is not a luxury, but a necessity, critical to our survival just as much as food and water. In the chapter 'Sleep and Health', Walker meticulously discusses how sleep deprivation affects everything from our immune system to our risk of developing serious diseases like Alzheimer's. The author takes a deep dive into the science behind sleep, using examples like REM sleep and its role in creativity and problem-solving. Despite its engaging exploration of the myriad roles sleep plays, the book does not offer much for those seeking in-depth psychological analysis of dreams or their meanings. Walker's writing is accessible and informative, but if you are looking for a book that delves into the psychology of dreams, this might not be the one for you.
