Key point
If sleep problems affect your days, ask about CBT-I and bring a short sleep diary to the conversation.
Symptoms and daytime effects
Insomnia can involve difficulty falling asleep, staying asleep, or both, despite sufficient opportunity and suitable conditions for sleep, with effects on daily life. 5 Clinicians consider how often it happens, how long it has continued, and how it affects daily life. NHLBI describes chronic insomnia as occurring at least three nights a week for three months or longer. These thresholds describe a clinical pattern; they are not a requirement to wait three months before asking for help. 1
Describe the problem in concrete terms. Is settling into sleep difficult? Are you awake for long stretches after an initial sleep? Does the problem happen only before an early start? What changes on days off? Also mention snoring, gasping, new medicines, pain, and changes in mood or health. These details help the clinician identify contributors and assess overlapping sleep conditions. 1
What CBT-I involves
Cognitive behavioral therapy for insomnia, usually shortened to CBT-I, is a structured treatment. It can include work on sleep-related worry, relaxation skills, education, and changes to the relationship between time in bed and sleep. NHLBI describes a typical course lasting six to eight weeks, delivered in person, by telephone, or online. 2
Stimulus control helps rebuild an association between bed and sleep. A prescribed sleep window adjusts time in bed as treatment progresses. Cognitive work addresses expectations and worry that make sleep feel like a task with high stakes. A provider uses the person's sleep pattern to decide how to combine and adapt these components. 2
Why sleep hygiene alone has limits
The American Academy of Sleep Medicine strongly recommends multicomponent CBT-I for chronic insomnia in adults. It recommends against sleep hygiene as the only treatment. Advice about caffeine, noise, or a regular routine can still be useful within care; the limitation is relying on it alone when an insomnia disorder persists. 3
If you have improved your room and evening habits but still struggle to sleep, ask about CBT-I. CBT-I usually produces gradual change, so discuss how progress will be assessed across weeks. A single difficult night during treatment is a poor measure of the whole course. 3
In-person, telephone, and digital CBT-I
In a randomized trial involving 1,711 people reporting insomnia symptoms, a specific digital CBT program improved sleep-related quality of life more than online sleep-hygiene education. Benefits extended to measures of daytime health and well-being, with follow-up through 24 weeks. 4
The result supports a studied treatment format, not every app labeled for sleep. Participants were predominantly women and White, and the outcomes were self-reported. When considering a digital option, ask whether it actually delivers CBT-I, what evidence supports that program, and what help is available if the plan is difficult to follow. 4
Sleep-window changes can initially increase sleepiness. Tell the provider about safety-sensitive work, excessive daytime sleepiness, a history of mania or hypomania, or poorly controlled seizures: sleep restriction may be unsuitable or need a different plan. This concern applies to that treatment component, not automatically to all CBT-I. Do not turn sleep restriction into an unsupervised challenge to function on as little sleep as possible. 3
Preparing for an insomnia appointment
Keep a simple diary for one to two weeks: bedtime, estimated sleep, awakenings, wake time, naps, and daytime sleepiness. Include caffeine, alcohol, exercise, and medicines when relevant. Approximate observations are enough to start a conversation; the purpose is to reveal a pattern. 1
At the appointment, ask which features suggest insomnia, whether another sleep disorder needs investigation, and how to access CBT-I. Ask what the proposed plan is intended to change and when it should be reviewed. If medication is discussed, include expected benefits, adverse effects, and the follow-up plan in that conversation. NHLBI notes that treatment can involve behavioral care, medication, or both, depending on the situation. 2
