My rating: 4 of 5 stars
This is one book in a large series of books put out by the Oxford University Press. All of these “Very Short Introduction” books are brief summaries of the state of research on a given topic in the arts, sciences, or humanities. Based on this book, I’d say the series is geared toward a readership of educated non-specialists. I say “educated” because the book did get into some technical areas, and while it doesn’t presume any particular knowledge of the science of sleep, it does use a scientific vocabulary with occasional academic sentences (i.e. packed with precise detail and lacking concern about readability.) That said, I’d say the readability is higher than the journal articles from which the information for the book was drawn. I suspect I’ll read more from this series. They are cheap on Kindle, provide a concise injection of the basics for a wide range of topics, and are pleasantly readable if you’re used to reading academic literature.
This particular book is about sleep. While, on average, sleep takes up one-third of a person’s life, it’s a subject that is often taken for granted. Like water, one doesn’t really think about it until one isn’t getting enough. However, as the book discusses in detail, all sorts of problems are associated with sleep deprivation, insomnia, and parasomnias (i.e. sleep events like sleepwalking, night terrors, nightmares, bedwetting, sleep-eating, and groaning.)
The book is written in nine chapters covering: the history of sleep, sleep generation and regulation, a brain on sleep, reasons we sleep, variation in sleep throughout one’s life-cycle, the nature of poor sleep, the connection between sleep and health, and the effect of our shift to a round-the-clock society.
There are a number of fascinating questions addressed by this book including:
1.)What does sleep do for us?
2.)Have people always tended to sleep eight hours per night?
3.)Why are some people morning people and others night owls?
4.)Why does one feel drowsy after lunch, but not necessarily when it’s time to hit the sack?
5.)How long can one go without sleep?
6.)Do all animals sleep?
7.)How do sleep and hibernation differ?
8.)Why do teenagers and the elderly have such odd (but different) sleep habits?
9.)Why do people sleepwalk, sleep-eat, groan in their sleep, or have night terrors?
10.)What is the effect of long-term insomnia on health?
11.) What happens to sleep if one has no rising and setting sun cues?
12.)What is jetlag and how can one fight it?
I learned some interesting facts, such as:
1.) On average, women report more insomnia, but, paradoxically, tend to sleep better than men.
2.) Pre-industrial people slept for about 10 hours a night on average, it’s believed.
3.) Many parasomnias occur mostly during REM (Rapid Eye Movement) sleep.
4.)The government can deprive prisoners of sleep for 7.5 days without it being considered torture (then they have to allow a full 8 hours sleep before another 7.5 day period started.)
5.) Long-term insomnia has been linked to heart-disease.
6.)Shift workers have a 50% greater incidence of breast and prostate cancer than day-workers.
7.)Visiting teams win 46% of the time if they are in their home time zone, 44% if they are traveling ‘with their body clock,’ and only 37% if they are traveling against their body clock.
I found this book interesting and informative. However, there are many books on the subjects of sleep and dreams that are more catered to a popular audience. Such books delve into intriguing cases and don’t dig as deeply into the minutiae of the science of the subject. I’d recommend this book, but not for readers who get bogged down or bored with scientific and technical discussions. If you’re looking for a book that’s loaded with pithy facts and fascinating stories, you can find a book closer to the mark by journalists who focus on science writing and who’ve got more flare for creative writing.
