We spend approximately a third of our lives sleeping, and Alice Gregory discusses how sleep affects our mental and physical health, work performance, family relationships, and more. Sleep can be comforting or elusive (picture a frustrated individual tossing and turning at night, unable to settle into a comforting and restorative slumber). Whether someone is in pain, has kids who do not sleep well, is worried about job-related matters, or is addicted to electronic devices, he or she may end up sleep-deprived and unable to function properly during the day.
Gregory, who has a PhD and has written many scholarly papers about sleep, admits that there is still a great deal that we do not understand about this subject. Nevertheless, she presents intriguing ideas based on a host of studies that scientists have conducted over the years. Most of us know that the need for sleep changes as we age. The author discusses why we sleep differently as babies than we do as toddlers, teenagers, adults, and senior citizens. She focuses on various parts of the brain that affect sleep, different types of sleep (such as REM), and various sleep disturbances, including insomnia, night terrors, sleepwalking, narcolepsy, and even hallucinations.
"Nodding Off" is an entertaining and informative book about a topic that affects us all, but it may be too technical and detailed for the average reader. Gregory presents reams of data that touch on the possible ways that genetics, circadian rhythms, light, and our environment may affect our ability to sleep soundly. What is clear is that sleep remains a problem for many; pills and supplements are not a cure-all; we should ban televisions, cell phones, and other electronics from the bedroom; and carefully thought-out bedtime routines may help us enjoy more restful nights. Gregory urges us to consult our physicians if we have physical or emotional issues that adversely affect our ability to sleep. Sleeplessness or disturbed sleep can impair our aptitude for learning and remembering, disrupt households, and cause fatal accidents. "Nodding Off" does not provide many definitive answers, but it does introduce readers to promising areas of research.
