Snoozefest: The Surprising Science of Sleep

Scientists are discovering increasing evidence that sleep is more important to health than was originally thought. Snoozefest: The Surprising Science of Sleep takes a fascinating look at the science of sleep and the history of sleep research. Divided into five chapters, the book covers topics such as stages of sleep, dreams, sleep patterns and cycles, sleep deprivation, the benefits of sleep (from cell regrowth and heart health to stronger bones, increased muscle mass and better immunity, to name just a few), sleep disorders, and tips for a good night’s sleep. The analysis of sleep patterns not only helps doctors to treat jet lag in their patients, but it also aids in the scheduling of shift work in hospitals and class start times in middle and high schools (it has been proven that later start times result in higher marks). Sleep also serves as a main filter that determines what information is stored in people’s memories and what gets discarded, and, interestingly, can help people to solve problems while they slumber, resulting in “eureka” moments. Other topics include the effects of blue light, how astronauts sleep in outer space, and adaptations which allow animals to sleep in safety from predators, an example of which is the ability of dolphins to shut down only one side of their brain at a time and alternate sides every few hours. Sidebars provide additional relevant information.

Though the book’s subject matter might not appeal to everyone, the author hooks readers and engages them throughout with a winning combination of a conversational writing style infused with humour and her use of analogies to explain some sleep concepts. Fun, cartoon illustrations add visual appeal and are well suited to the text. A table of contents, an index and a list of print and online resources are included.
Full of valuable information, Snoozefest is both educational and entertaining. Definitely not a snoozefest!
