UCLA Health links cognitive behavioral therapy for insomnia to slower biological aging, offering practical recovery insights for adult racquet sports players.
In September 2026, UCLA Health researchers reported in The Lancet Healthy Longevity that older adults receiving cognitive behavioral therapy for insomnia achieved higher insomnia remission rates and a slower pace of biological aging than participants receiving sleep education. This clinical trial highlights a critical intersection between sleep science and athletic longevity for adult racquet sports players. Rather than viewing poor rest as an inevitable part of getting older, the findings suggest that structured clinical intervention can measurably alter how the body ages at a cellular level. For tennis, pickleball and padel players, this adds substantial evidence that addressing chronic insomnia is vital for maintaining physical capacity.
The research team conducted a secondary analysis of a randomized controlled trial involving nearly 100 older adults with insomnia. Participants were assigned to either cognitive behavioral therapy for insomnia (CBT-I) or sleep-education therapy for an eight-week period. CBT-I targets the specific thoughts and behaviors that perpetuate insomnia and is generally delivered over multiple sessions with a trained clinician. In contrast, the control group received general information about healthy sleep habits without incorporating specialized behavioral techniques.
To measure the physiological impact of these treatments, researchers collected blood samples before the eight-week treatment period began and again during follow-up visits over the next two years. The scientific team assessed biological aging using three distinct DNA-methylation-based measures: the DunedinPACE, GrimAge, and PC-PhenoAge epigenetic clocks. Participants receiving CBT-I had a nearly threefold greater likelihood of insomnia remission than those receiving standard sleep education. Furthermore, the CBT-I group demonstrated a statistically significant slowing of their biological-aging pace according to the DunedinPACE clock.
The study’s lead author, Judith Carroll, noted that these findings suggest insomnia may be a modifiable risk factor for how the body ages rather than merely a quality-of-life issue. Carroll compared sleep directly with physical activity and diet as a behavior worth targeting to support healthy aging. However, the researchers clarified that the study did not establish that CBT-I makes a person literally younger or directly extends lifespan. The reported outcome was specifically a change in an epigenetic aging measure, emphasizing the need for targeted behavioral therapy.
Professional racquet sports athletes often treat sleep hygiene as a minor margin to optimize tournament performance. For the adult recreational player, persistent insomnia is rarely just a minor performance leak. It is a fundamental barrier to healthy aging, consistent court time, and everyday physical comfort. The UCLA Health trial confirms that resolving actual insomnia requires structured clinical intervention rather than adopting generic advice to sleep better.
Our team at Evercourts has experienced the tangible difference between simple fatigue and actual recovery deficits. "I used to think a tough conditioning block was the only way to improve my court endurance. Then I started tracking my sleep."
The impact of poor rest became immediately apparent during competitive play. "I noticed that on days I slept less than six hours, my reaction time at the net was noticeably sluggish, and I felt gassed by the second set. Prioritizing consistent rest did more for my late match stamina than any extra sprints ever did. Recovery is the true foundation of performance."
According to a 2026 review of sleep and athletic performance, adequate rest directly supports muscle recovery and cognitive function. Conversely, sleep deprivation is associated with impaired physical and mental performance, greater fatigue, and higher injury risk. While smart court strategy keeps racquet players healthy, those tactical adjustments cannot replace the biological necessity of sleep. Addressing chronic insomnia with a qualified professional ensures players can safely tolerate their weekly training loads.
The data from the UCLA Health analysis provides concrete metrics on how behavioral health impacts physical aging. The report states that approximately 10% to 25% of U.S. adults older than 65 currently suffer from clinical insomnia. For this demographic, the finding that participants receiving CBT-I had a nearly threefold greater likelihood of insomnia remission is clinically substantial. Measuring these changes over a two-year follow-up period demonstrates the lasting impact of the eight-week intervention.
While CBT-I addresses the crucial recovery side of the longevity equation, complementary research highlights how court time supports functional fitness. A reported eight-week randomized pickleball intervention in older adults with pre-frailty provided parallel evidence for active routines. That separate study found that 42% of participants assigned to pickleball were no longer classified as pre-frail, compared with just 8% in the control group. Together, these statistics show that managing racquet sports training load alongside rigorous sleep support can drastically improve long-term health.
However, researchers noted several caveats regarding the epigenetic data collected during the study. The UCLA analysis was conducted at a single site in Los Angeles, which limits how confidently the results can be generalized to older adults in other locations. Furthermore, epigenetic clocks are measurement tools rather than direct measurements of remaining lifespan, future athletic ability, or disease-free years. The study also did not determine whether treatment effects differ by sex, prompting authors to call for larger, multisite research.
The researchers also stated that further work is needed to assess whether other treatments, including medication or Tai Chi, produce similar effects on aging measures. Because the study was a secondary analysis of a randomized trial, the biological-aging findings should not automatically be treated as the primary clinical outcome of CBT-I. Additionally, players should avoid using this specific study to justify training harder simply because they have begun therapy. The evidence specifically concerns insomnia remission and epigenetic aging, not proof of improved match performance or faster recovery from heavy workloads.
Over the next season, expect coaching frameworks and adult league structures to place a heavier emphasis on sleep as a primary performance metric. League organizers are increasingly recognizing that scheduling demanding sessions requires careful attention to rest and recovery. Treating persistent sleep problems as a medical issue that warrants clinical support offers a highly sustainable path for older adult athletes. Coaches will likely encourage players to view sleep quality as a necessary foundation for safe, long-term participation.
As the complete sleep guide for racquet sports emphasizes, addressing persistent sleep issues early can prevent cascading physical problems. Players with ongoing insomnia should take the practical step of discussing their symptoms with a qualified healthcare professional to ask whether CBT-I is appropriate. Persistent insomnia in an older adult may require a comprehensive assessment to rule out medical, psychiatric, or medication-related causes. Ultimately, successful athletic longevity will rely on combining active court time with rigorous, evidence-based recovery protocols that respect the biological demands of aging.
