How to Treat Insomnia: What Actually Works and When to Get Help

What is CBT-I and why is it the recommended first-line treatment?

Cognitive Behavioral Therapy for Insomnia (CBT-I) is the first-line treatment for chronic insomnia according to major sleep medicine organizations 1Ref 1Edinger JD, Arnedt JT, Bertisch SM, et al. (2021).Behavioral and Psychological Treatments for Chronic Insomnia Disorder in Adults: An American Academy of Sleep Medicine Clinical Practice Guideline.CBT-I as the first-line treatment for chronic insomnia per AASM clinical practice guideline. It is not generic talk therapy — it is a structured, evidence-based program typically delivered in 4 to 8 sessions. A systematic review and meta-analysis found it produces durable improvements in sleep onset, sleep efficiency, and wake time after sleep onset 2Ref 2Trauer JM, Qian MY, Doyle JS, Rajaratnam SMW, Cunnington D (2015).Cognitive Behavioral Therapy for Chronic Insomnia: A Systematic Review and Meta-analysis.Meta-analytic evidence that CBT-I produces durable improvements in sleep onset, efficiency, and wake time after sleep onset.

CBT-I addresses the thoughts and behaviors that maintain insomnia. The core components include:

Sleep restriction therapy: Temporarily limiting time in bed to consolidate sleep. Counterintuitive but highly effective. Stimulus control: Retraining the brain to associate the bed with sleep — not wakefulness, screens, or worry. Cognitive restructuring: Addressing unhelpful thoughts about sleep, such as catastrophizing a single bad night. Sleep hygiene: Environmental and behavioral adjustments — a component of CBT-I, not the whole treatment. Relaxation techniques: Reducing physical and mental arousal before bed.

CBT-I is available through licensed psychologists and therapists who specialize in behavioral sleep medicine. Digital versions also exist and have been studied, though they work best with some clinician guidance.

Where do sleep medications fit in?

Sleep medications can be useful in the short term — for situational insomnia triggered by grief, travel, or acute stress, or to provide relief while starting CBT-I. They are not a long-term solution for chronic insomnia and carry real risks with extended use.

There are several categories of prescription sleep aids, over-the-counter options, and supplements. No specific dose or regimen should be started or changed without talking to a clinician or pharmacist — this is especially important for older adults, people with liver or kidney disease, and anyone taking other medications.

Some over-the-counter sleep aids (typically containing antihistamines) can cause tolerance quickly, impair memory, and in older adults, increase fall risk. They are not recommended for chronic use. A clinician who knows your full picture — not a search result — is the right person to weigh in on whether and which medication makes sense.

What can you do tonight while you arrange care?

A few evidence-informed habits can help while you arrange professional care. These are not a substitute for treatment but will not worsen your situation:

Get up if you cannot sleep. If you have been in bed awake for more than roughly 20 minutes, get up, go to a dim room, and do something quiet — reading, light stretching. Return to bed only when sleepy. This breaks the association between bed and being awake.

Keep a consistent wake time. This is the most powerful behavioral lever for sleep 3Ref 3Watson NF, Badr MS, Belenky G, et al. (2015).Recommended Amount of Sleep for a Healthy Adult: A Joint Consensus Statement of the American Academy of Sleep Medicine and Sleep Research Society.Consistent sleep timing as a foundational behavioral lever for sleep health. A consistent wake time anchors your circadian rhythm — even if you slept poorly the night before, keep the same wake time.

Reserve the bed for sleep only. No phones, television, laptops, or work in bed. The goal is for your brain to associate bed with sleep automatically.

Limit evening alcohol and caffeine. Alcohol may help you fall asleep but disrupts sleep architecture in the second half of the night 4Ref 4Ebrahim IO, Shapiro CM, Williams AJ, Fenwick PB (2013).Alcohol and Sleep I: Effects on Normal Sleep.Alcohol disrupts sleep architecture in the second half of the night despite facilitating sleep onset. Caffeine can persist in your system longer than expected 5Ref 5Drake C, Roehrs T, Shambroom J, Roth T (2013).Caffeine Effects on Sleep Taken 0, 3, or 6 Hours before Going to Bed.Caffeine consumed several hours before bed persists and disrupts sleep.

Reduce clock-watching. Checking the time during the night amplifies anxiety about sleep. Turn the clock away.

When is self-help not enough?

If you have tried sleep hygiene changes for several weeks without improvement, or if insomnia is affecting your work, relationships, or mood, a clinician visit is the right next step.

Start with primary care if you have a relationship there — they can rule out medical causes, screen for anxiety or depression (which are tightly linked with insomnia), and refer to a behavioral health clinician for CBT-I if appropriate. A validated tool such as the Insomnia Severity Index is sometimes used to characterize severity and track treatment response 6Ref 6Morin CM, Belleville G, Bélanger L, Ivers H (2011).The Insomnia Severity Index: Psychometric Indicators to Detect Insomnia Cases and Evaluate Treatment Response.The Insomnia Severity Index as a validated tool for characterizing severity and tracking treatment response.

A therapist or psychologist who offers CBT-I is often the most effective path for chronic insomnia without a clear medical cause. The optimal duration of maintenance CBT-I after improvement is still being studied.
