As part of the Harvard Medical School Guides, this book comes with considerable stature. It begins with an excellent chapter on the ABC's of sleep in which the science of sleep is discussed. In particular, the various types of brain waves and stages of sleep are examined. The following chapter deals with how much sleep we need; the author states that on the average Americans get 6.9 hours a night, and needs about 7.5. He emphasizes however, that there is a relatively large range in people. A particularly interesting chapter is one on sleep "myths," and one of the myths he explores is whether or not you need less sleep as you age.
A central feature of the book is a 6 step plan for better sleep. This includes such things as a healthy lifestyle, maintaining good sleep habits, and watching for sleep sabateurs. He also has a long section on various sleep disorders such as insomnia, sleep apnea,and narcolepsy, and he does a good job of discussing each. In particular, he suggests treatments for each.
His discussion of sleep medications is more complete than those in most sleep books. He talks about most of the medications on the market, both over-the-counter and prescription, and he give his opinion of many of them. Like most sleep specialist, he does not strongly recommend sleeping pills, but points out the they do have their place. He also discusses herbs such as valerian and melatonin.
Overall the book contains a lot of useful information, and of course the author is a sleep specialist. It contains a more detailed discussion of the science behind sleep than "Good Night" by Michael Breus, and in general compares well with it. Although the two books cover many of the same topics, they compliment one another. One slight drawback is that it has no bibliography.
