CBT-I for older adults: what the trials show

A long timeline of dots that grow larger along its length

CBT-I works in older adults, and some of the strongest evidence for it comes from trials run in older adults specifically. That matters, because sleeping pills are prescribed often in later life, and the comparison between the two has been tested directly in this age group.

The head-to-head trial

One of the most-cited CBT-I trials was a double-blind, placebo-controlled study in older adults with chronic insomnia, comparing CBT with the sleeping pill zopiclone and with placebo. Sleep was measured objectively with polysomnography, not just reported.

At six weeks, sleep efficiency - the share of time in bed actually asleep - rose from 81.4% to 88.9% in the CBT group. In the zopiclone group it went from 82.3% to 81.5%. Total wake time fell by 52% with CBT, against 4% with the drug. At six months, the CBT group was at 90.1% and the medication group at 81.9%.

Total sleep time did not differ significantly between the groups. That is consistent with the wider evidence: CBT-I consolidates sleep rather than lengthening it. What CBT-I does and does not change.

Coming off sleeping pills

A second trial, also in older adults with chronic insomnia, looked at people taking benzodiazepines who wanted to stop. A supervised taper combined with CBT left 85% medication-free, against 48% with the taper alone and 54% with CBT alone.

That was a planned, supervised reduction - not stopping on your own. What the research says about coming off sleeping pills, and why that conversation starts with your prescriber.

What the guidelines say

The American College of Physicians recommends CBT-I as the initial treatment for all adults with chronic insomnia - there is no upper age limit on that. The American Academy of Sleep Medicine's medication guideline makes fourteen drug recommendations, and all fourteen are weak, on low or very low quality evidence. Its behavioral guideline strongly recommends multicomponent CBT-I.

Newer, more preliminary evidence

A 2026 secondary analysis of a trial in adults aged 60 and over found that those who received CBT-I showed a slower pace of biological aging on one epigenetic measure than those who received sleep education. It was a small, preliminary analysis, two of the three measures used showed no difference, and the authors call for replication. What it found, and why it should be read carefully.

What changes after sixty

Sleep naturally changes with age

Lighter sleep and more night wakings are common in later life. Not every change is insomnia; insomnia is when difficulty sleeping is frequent, persistent and affecting the day. What counts as insomnia.

Sleep restriction needs care

It increases daytime sleepiness before it improves sleep. For anyone for whom sleepiness carries particular risk, the window should be set conservatively and planned with a clinician.

Other causes are more common

Sleep apnea, pain, nighttime urination and medication side effects all become more likely with age, and all can drive poor sleep. When to see a sleep specialist first.

Naps deserve a second look

Daytime napping is common in retirement, and it quietly spends the sleep pressure the night needs. Should you nap if you have insomnia?

The short version

Age is not a reason to skip CBT-I. If anything, the evidence in older adults is some of the clearest there is, and the comparison with medication was tested in exactly this population. What CBT-I involves, and the rest of this section.

Somnera is a self-guided education program built on CBT-I, founded and written by Dr. Camilo Ruiz, DO, FACOI, FAASM. It is not a diagnosis and does not replace care from your own clinician. The assessment is free and takes about two minutes.

Frequently asked questions

Yes. Some of the most-cited CBT-I trials were run specifically in older adults, including a double-blind trial in which CBT improved measured sleep efficiency where a sleeping pill did not. Guidelines recommend CBT-I as first-line for all adults with chronic insomnia.

In one trial in older adults, sleep efficiency measured in a sleep lab rose from 81.4% to 88.9% with CBT, while the zopiclone group went from 82.3% to 81.5%. At six months the CBT group was at 90.1% and the medication group at 81.9%.

In a trial of older adults taking benzodiazepines, 85% of those given a supervised taper combined with CBT were medication-free afterwards, against 48% with the taper alone. Any change to medication should be planned with a prescriber.

It can be done, with care. Sleep restriction increases daytime sleepiness before it improves sleep, so anyone for whom sleepiness carries particular risk should plan it with a clinician.
