CBT for insomnia slowed DunedinPACE aging vs sleep education in adults 60+
Source: UCLA Health
What the research found
Study (secondary analysis of an RCT). Judith Carroll and UCLA colleagues report in The Lancet Healthy Longevity that older adults with insomnia who received 8 weeks of CBT-I were more likely to remit (34% vs 13%) than a sleep-education control, and showed a slower DunedinPACE pace of aging (−0.02, FDR p=0.03) over ~2 years. GrimAge and PCPhenoAge did not differ significantly. Single-site, n≈92. Educational aging notes, not a longevity drug.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
