Cognitive behavioral therapy may reduce biological aging among older adults with insomnia

What the research found
Study. UCLA Health researchers (Judith Carroll and colleagues) report in The Lancet Healthy Longevity a secondary analysis of a randomized trial: 92 older adults with insomnia (mean age about 69.5; 47 CBT-I, 45 sleep education). After eight weeks, CBT-I tracked with a nearly three-fold greater chance of full insomnia remission (34% vs 13%) and a slower DunedinPACE epigenetic aging pace (−0.02, 95% CI −0.04 to −0.01). Blood was drawn before treatment and across two years of follow-up. This is not a lifespan trial and not a sleep-drug substitute. Educational sleep-behavior notes, not medical advice.
Evidence level: Clinical trial. This is among the stronger kinds of evidence, but one study rarely settles a question.
