Wide Awake at 3:00 A. M. shows you how your biological clock (or sleep-wake cycle) works and how it controls periods of sleep, alertness, mood, and performance. It offers you techniques you can use to reset your own biological clock to minimize common disruptions, such as the discomforts of jet lag, insomnia, depression, fatigue, or changes in your work schedule. A nontechnical, state-of-the-art account of sleep research and therapy, WIDE AWAKE AT 3:00 A. M. reports on a series of innovative sleep-wake studies (including first-hand investigations by Dr. Coleman) that have culminated in practical applications to sleep and alertness problems, characteristics of many areas of modern technological society. A helpful and authoritative aid to improving your own sleep-wake patters of behavior, WIDE AWAKE AT 3:00 A. M. presents fascinating information on the effects of changes in cycles of sunlight and darkness, on shift schedules, on travel across time zones, and on the nature of sleep and dreams. In addition, Dr. Coleman explores the mysteries of REM (rapid eye movement) sleep, narcolepsy, sleep apnea, dreams, and night terrors. For all those who want to be more alert, improve their (day or night) work performance, and improve the quality of their sleep, WIDE AWAKE AT 3:00 A. M. will prove to be an invaluable guide. -- from back cover.
