Researchers from the University of Sao Paulo in Brazil have uncovered a potential link between sleep apnea, a breathing disorder commonly connected with snoring, and accelerated biological aging. The findings appear in materials published by the Society for Sleep Research (SRS).
The study enrolled forty-six men aged 50 to 60 who exhibited moderate to severe sleep apnea. Sleep apnea is characterized by pauses in breathing lasting at least ten seconds during sleep. After reviewing the participants’ health data, the investigators observed that telomeres—the protective caps at the ends of chromosomes—shrank more quickly in those with apnea, signaling faster cellular aging. Telomeres function to prevent chromosomes from fusing and to regulate how many divisions cells can undergo. With each cell division, telomeres shorten, and when they become critically short, cells lose their ability to repair damage and perform essential tasks. These mechanisms help explain why aging-related changes may appear sooner in individuals with untreated sleep apnea. Source: SRS study briefing
To determine if apnea directly influences telomere shortening, the participants were divided into two groups. The first group received CPAP therapy (Continuous Positive Airway Pressure), a standard treatment that keeps the airways open by delivering a steady stream of air. The same equipment was used to simulate the treatment in the second group, ensuring a controlled comparison.
At the study’s conclusion, researchers found that CPAP treatment slowed the rate of telomere shortening in the first group, while the second group showed no improvement. The results suggest that managing sleep apnea with CPAP may help mitigate some cellular aging processes associated with the condition. Source: SRS study briefing
These findings add to a growing body of evidence that sleep health can influence aging at the cellular level. The researchers emphasize that addressing sleep apnea could have broader health benefits beyond symptom relief, potentially lowering risks linked to aging-related diseases. The study also highlights the importance of early diagnosis and consistent use of effective therapies for sleep-disordered breathing. Source: SRS study briefing
In the broader scientific context, prior work has explored how sleep quality relates to cognitive health and dementia risk, reinforcing the view that restful, uninterrupted sleep supports long-term neurological function. While this study focuses on telomere dynamics, it aligns with a landscape of research underscoring the significance of sleep for overall aging trajectories. The researchers hope their work will raise awareness about sleep apnea and encourage timely treatment to reduce adverse health outcomes. Source: SRS study briefing
Overall, the findings underscore a clear message: treating sleep disorders not only improves nighttime comfort but may also influence how the body ages at a cellular level. For individuals experiencing symptoms of sleep apnea, consulting a healthcare professional about testing and therapy options could be a meaningful step toward healthier aging. The study’s implications extend beyond sleep clinics, inviting clinicians and patients alike to consider the long-term cellular benefits of effective sleep-disordered breathing management.

Previous research has also highlighted connections between sleep quality and cognitive outcomes, further reinforcing the idea that sleep health is a key component of overall well-being across the lifespan. As the scientific community continues to explore these relationships, practical guidance for individuals remains simple: seek evaluation for sleep-related breathing problems, adhere to prescribed therapies, and prioritize regular, restorative sleep as part of a holistic approach to health.
