Study
Cognitive Therapy May Slow Aging in Older Adults with Insomnia
Older adults who received cognitive behavioral therapy for insomnia showed a slower biological aging process compared to those who received sleep education.
Summary
In plain language
In a recent study, researchers found that cognitive behavioral therapy for insomnia (CBT-I) could slow down the biological aging process in seniors. The study compared two groups of adults aged 60 and older: one received CBT-I, and the other received sleep education therapy (SET). Results showed that those who underwent CBT-I experienced a slower pace of biological aging over time. This finding is important because it suggests that treating insomnia with CBT-I might not only help improve sleep but also help maintain overall health as we age. Seniors experiencing insomnia may want to discuss this therapy option with their healthcare providers to explore its potential benefits.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This study was a secondary analysis of a larger trial involving older adults aged 60 and above who suffered from insomnia. Participants were randomly divided into two groups: one received cognitive behavioral therapy for insomnia (CBT-I), and the other received sleep education therapy (SET).
Researchers collected blood samples from participants before and after treatment to assess biological aging using epigenetic clocks.
Findings showed that those who received CBT-I had a significantly slower pace of biological aging compared to the SET group, as measured by the DunedinPACE epigenetic clock.
While the study suggests potential benefits of CBT-I in slowing biological aging, more research is needed to confirm these findings and explore the long-term impact.
If you're experiencing insomnia, consider discussing CBT-I with your healthcare provider to see if it might be a suitable option for you.

Research Quality Score
Scored September 22, 2026 using rubric mq-1.8_2026-07-06.
Assessment
The study scored highly due to its rigorous RCT design and robust statistical methods. Bias control was strong with randomization and blinding of outcome assessors, though participant blinding was not mentioned. Transparency was limited by conditional data sharing. The study is highly relevant to the target population of older adults. No external replication was cited, which limited the replication score.

Additional Notes
This study is a secondary analysis of a randomized controlled trial examining the effects of cognitive behavioral therapy for insomnia (CBT-I) on biological aging in older adults. It found that CBT-I may slow the pace of biological aging as measured by epigenetic clocks compared to sleep education therapy.

Conditions This Research Covers
These condition pages help connect the paper back to the real-world health concerns it addresses.
Insomnia
Insomnia, characterized by difficulty falling asleep, staying asleep, or waking up too early, is a common sleep disorder that can significantly impact quality of life. It can be acute, lasting for a short period, or chronic, persisting for months or years. While insomnia can affect people of all ages, it is particularly prevalent among older adults.
Skin Aging and Wrinkles
Skin aging and wrinkles are natural parts of getting older, affecting everyone as they age. These changes can include fine lines, deeper creases, and a loss of elasticity and moisture in the skin, impacting its appearance and texture. While inevitable, understanding the causes and potential treatments can help manage their effects.
Treatments Evaluated in This Research
Review the interventions studied here and compare them against the broader treatment library.
Sleep Wellness
Sleep Wellness is a holistic approach designed to help seniors improve their sleep quality. It combines lifestyle changes, relaxation techniques, and environmental adjustments. This treatment is beneficial for older adults struggling with insomnia or poor sleep, supporting overall health and vitality.
Cognitive Behavioral Therapy (CBT)
Cognitive Behavioral Therapy (CBT) is a structured form of talk therapy that helps individuals recognize and change negative thought patterns and behaviors. It’s one of the most widely researched and effective treatments for anxiety, depression, and stress. For older adults, CBT can improve coping skills, mood, and confidence in managing life’s challenges.
