The author, Arianna Huffington, is the editor-in-chief of the Huffington Post and author of several other books. Her inspiration for this book came when suffering an injury caused by lack of sleep, resulting in a remaking of her sleep habits and in-depth research of the science of sleep.
Huffington identifies sleep deficiency as a worldwide problem, causing traffic accidents, susceptibility to illness, poor work performance and more. People often tout how little sleep they can get along on and still function well. But scientific studies reveal that adults must sleep between seven and nine hours in order to be at their best.
Also included are appendices: a sleep-quality questionnaire, guided meditations to help in falling asleep, a list of hotels that focus on the sleep experience, and a review of mattresses for consumers. In-depth bibliographic information is given also.
