Sleep hygiene and the behavioral treatment of insomnia
- Technique
Regular habits help sleep, but chronic insomnia responds best to cognitive behavioral therapy for insomnia, which retrains the link between bed and sleep.
What it is
Sleep hygiene is a set of habits and environmental conditions that favour sleep: regular times, a dark, quiet and cool bedroom, and limits on caffeine, alcohol, heavy meals and screens before bed. On its own it rarely cures chronic insomnia. Cognitive behavioral therapy for insomnia (CBT-I) adds stimulus control, sleep restriction, relaxation and cognitive work on sleep worries, and is the recommended first treatment for chronic insomnia.
How it is done
- Keep a sleep diary for one to two weeks: bedtime, time to fall asleep, awakenings, wake time, naps, caffeine and alcohol.
- Look for medical, psychiatric and medication causes and for other sleep disorders (apnea, restless legs) before labelling insomnia.
- Education and sleep hygiene: regular times, dark and cool room, no caffeine late in the day, no alcohol as a sleep aid, screens away before bed.
- Stimulus control: the bed is kept for sleep; the person goes to bed when sleepy and gets up if unable to sleep, returning when sleepy.
- Sleep restriction: a time-in-bed window equal to the average sleep time from the diary, with a fixed wake time every day.
- Weekly review: the window is lengthened when sleep efficiency is high and shortened when it is low.
- Relaxation training: progressive muscle relaxation, slow breathing or imagery to reduce arousal at bedtime.
- Cognitive therapy: reframing catastrophic beliefs (‘if I don't sleep eight hours I'll fail tomorrow’) and reducing clock-watching.
Components of cognitive behavioral therapy for insomnia (CBT-I)
| Component | What it targets | Main mechanism |
|---|---|---|
| Stimulus control | Bed linked to wakefulness and worry | Reconditioning the bed as a cue for sleep |
| Sleep restriction | Long, fragmented time in bed | More sleep pressure, consolidated sleep |
| Relaxation | Physical and mental arousal at bedtime | Lower arousal |
| Cognitive therapy | Worry and false beliefs about sleep | Less anxiety about sleep loss |
| Sleep education and hygiene | Habits that disturb sleep | Removing obstacles; not enough alone |
Clinical notes
- Sleep restriction causes daytime sleepiness at first; it is used with caution in people who drive for work, have epilepsy or bipolar disorder.
- Restless legs, which worsen in the evening at rest, are a separate condition and need their own evaluation; behavioral measures alone are not enough.
- Over-the-counter antihistamine sleep aids lose effect quickly, and many hypnotics can create dependence, which is why behavioral treatment comes first.
- Digital and self-help versions of CBT-I extend access where trained therapists are scarce.

Think of the answer, then tap the question to see it.
What is the first-line treatment for chronic insomnia disorder in adults?
Cognitive behavioral therapy for insomnia (CBT-I), which combines stimulus control, sleep restriction, relaxation, cognitive therapy and sleep education.
What are the main instructions of stimulus control therapy?
Use the bed only for sleep and sex, go to bed only when sleepy, get up if unable to sleep and return when sleepy, keep a fixed wake time and avoid daytime naps.
How does sleep restriction therapy work?
It limits time in bed to the actual average sleep time, which raises sleep pressure and consolidates sleep; the window is then widened as sleep efficiency improves.
A patient spends 8 hours in bed and sleeps 6. What is the sleep efficiency?
75 % (6 ÷ 8 × 100), below the usual target of about 85 %.
