Cognitive behavioral therapy for insomnia slowed the pace of biological aging in older adults, as measured by epigenetic markers in a randomized controlled trial. This positions sleep quality improvement as a direct intervention on the aging process itself, not merely symptomatic relief.
Key Points
- CBT-I slowed epigenetic aging pace in older adults
- Effect persisted in secondary analysis of RCT data
- Sleep intervention addresses aging at molecular level
Longevity Analysis
Sleep disruption interferes with multiple regenerative processes—from glymphatic clearance during rest to hormonal consolidation and nervous system recovery. This work demonstrates that removing a primary interference (insomnia) can measurably alter the rate at which cellular aging progresses. For practitioners, it reframes insomnia treatment from symptom management to a direct lever on aging trajectory, particularly valuable in populations where pharmacological options carry burden.
