Summary: Goodnight Insomnia

The GIST

Say Good Night to Insomnia by Gregg D. Jacobs is a six-week, drug-free program for people who lie awake night after night and have started to dread their own beds. Jacobs is a behavioral sleep medicine specialist who spent decades at Harvard Medical School and the University of Massachusetts Medical School and is regarded as one of the principal developers of cognitive behavioral therapy for insomnia (CBT-I). The book, first published in the late 1990s and updated in 2009, puts on the page the course he ran for thousands of patients at a Harvard teaching hospital in Boston. Herbert Benson, author of The Relaxation Response, wrote the introduction.

Its promise rests on one hopeful claim: chronic insomnia is mostly a learned problem, kept alive by anxious thoughts, stress and well-meant bad habits, and what is learned can be unlearned. Pills, Jacobs argues, treat the symptom at best. The lasting fix is to retrain the body's sleep system and to change how you think about sleep, so that it becomes a friend again instead of an enemy. The publisher and Jacobs say the approach improves sleep over the long term for roughly eight in ten patients; those are their figures, not a guarantee, but they explain why the book has stayed in print for a quarter of a century.

The Big Ideas

Insomnia is learned, and the usual fixes feed it

The book opens with Alan, a composite patient watching bedtime approach with dread. The harder he tries to sleep, the more tense he gets, and his mind fills with worries about work, family and sleep itself: "I've got to get some sleep or I'll never function tomorrow!" Jacobs takes the emotional cost seriously. Insomniacs feel powerless and trapped, and being told to just relax, or that it is all in their head, only makes it worse.

A second patient, Carol, shows the trap. She tried to catch up by spending longer in bed and sleeping late on weekends, then turned to a glass of wine or a pill. Each step seemed sensible and each made her sleep worse. That is the book's first lesson: the natural reactions to a bad night are the very things that turn a rough patch into a chronic condition.

You need less sleep than you fear

Before changing anything, Jacobs teaches the basics of sleep stages and body rhythms, and introduces his most calming idea: core sleep. He argues that a fairly modest amount of deep, restorative sleep does most of the work, and that hours beyond it are welcome but not essential; readers often summarize his figure as about five and a half hours. The point is not to aim for short nights. It is to defuse the panic that a short night is a catastrophe. The updated edition also pushes back on alarming popular claims about short sleep and health.

Putting sleeping pills to rest

Jacobs devotes a chapter to medication: the older drugs, and in the 2009 edition the newer generation as well. He covers tolerance, rebound insomnia and how much of a pill's benefit may be placebo. His evidence includes a randomized, placebo-controlled trial he led, published in 2004, in which 63 adults with trouble falling asleep received CBT, medication, both or a placebo. By his account CBT did best on most measures and held its gains, the combination added nothing, and the benefits of the drug faded once it was stopped. For readers already taking pills, the book describes a gradual taper, to be done with a doctor's supervision and never abruptly.

Change your sleep thoughts

The cognitive half of the program begins with catching negative sleep thoughts: I must get eight hours, I'll never cope tomorrow, I'll never sleep normally again. Readers learn to challenge each one and replace it with something more accurate. Core sleep is enough to get by. One bad night will not ruin the next day. Daytime performance usually holds up better than expected. This is classic cognitive restructuring, and it matters because fear of not sleeping is itself a powerful cause of not sleeping.

Rebuild the habit of sleep

The behavioral core has two parts. Sleep scheduling, also called sleep restriction, means cutting time in bed to roughly match the time you actually sleep, getting up at the same time every day including weekends, and adding time in bed only as your sleep efficiency, the share of time in bed spent asleep, improves. Stimulus control means the bed is for sleep and sex only; if you cannot sleep, you get up, do something quiet and return when drowsy. Readers describe sleep scheduling as the hardest step, a real leap of faith, and the one that makes the biggest difference.

Lifestyle supports the schedule. Sleep comes more easily as body temperature falls, so exercise or a warm bath a few hours before bed sets up a helpful drop. Morning sunlight strengthens the body's clock. Jacobs also reviews caffeine, alcohol, nicotine and the bedroom itself: noise, light, temperature and the clock on the nightstand.

Calm the day to calm the night

The final part treats insomnia as a stress problem. Drawing on Benson's work, Jacobs teaches the relaxation response, a daily practice of focused breathing or a repeated word or phrase that switches off the stress response and, he says, produces brain-wave patterns like those of early sleep. It can be used at bedtime or after waking in the night. He then applies the same thought-challenging tools to daytime worries, and closes with broader attitudes, including optimism, humor, social support and positive belief, that make a person more resilient to stress and so more likely to sleep.

Putting It to Work

• Rule out other causes first. The self-assessment chapter sends readers with signs of sleep apnea, depression or another medical problem to a doctor.
• Keep a quick sleep diary. A minute each morning gives you your real time asleep and your sleep efficiency, and lets you see progress.
• Shrink your time in bed to about what you actually sleep, and get up at the same time every day.
• Get out of bed when you can't sleep. Reserve the bed for sleeping.
• Answer catastrophic thoughts with facts: core sleep protects you, and one bad night is not a crisis.
• Use light, movement and warmth. Morning sun, exercise in the late afternoon or early evening, and perhaps a warm bath a couple of hours before bed. Go easy on caffeine, alcohol and nicotine.
• Practice the relaxation response daily, not just when desperate.
• Taper pills only with your doctor.

Expect effort. Restricting time in bed can leave people more tired at first, and the program takes the full six weeks if followed step by step. Some readers find the stress-management chapters more generic than the sleep chapters, though many report quick results from the sleep habits alone.

Who Should Read It

This is for adults with long-running trouble falling or staying asleep who want a tested alternative to medication, and for people who rely on sleeping pills and would like to stop with their doctor's help. It will also suit readers curious about CBT-I or mind-body medicine. The tone is warm and reassuring, more like a guided course with worksheets and patient stories than a science book. It is less useful if your sleeplessness has an untreated medical cause.
