Question and answer

Summary

Age-related increases in sleep problems are closely tied to cardiovascular, cognitive, and physical declines. Sleep problems have often been assessed through symptoms or diagnosis of sleep disorders. However, the concept of sleep health transcends the mere absence of sleep disorders. Even individuals without sleep disorders can experience varying levels of sleep health, which has profound implications for their overall health and well-being.

The foundation for this perspective was laid in the landmark paper, "Sleep health: Can we define it? Does it matter?" (Buysse, 2014), which sparked a paradigm shift in sleep research. This shift emphasized a holistic view of sleep, encouraging researchers to focus on factors such as duration, efficiency, regularity, and quality, thereby adopting a preventive approach to sleep and its related health outcomes.

Over the past decade, research into sleep health and its implications for aging has expanded. However, the field remains relatively nascent, and there is a pressing need to promote this perspective globally, while also identifying future research directions. This symposium aims to bring together leading researchers to discuss how sleep health influences a variety of aging outcomes, including chronic pain, functional declines, cardiovascular disease, and cognitive outcomes. The presentations will draw on empirical evidence from diverse populations and contexts, highlighting the relevance of sleep health across different lived experiences.

Dr. Soomi Lee, the co-chair of this symposium, will open this symposium and present findings on multidimensional sleep health phenotypes and their longitudinal associations with pain, frailty, and chronic conditions. Her work incorporates data from both the U.S. and Asian populations. Following this introduction:
Dr. Heming Wang will present novel genetic findings on multi-dimensional sleep health using biobank data, highlighting how projecting sleep questionnaires into orthogonal sleep health domains can disentangle the heterogeneity of sleep traits and enhance genetic discovery.
Dr. Ryuji Furihata will share epidemiological findings from Japan, focusing on generational differences in multidimensional sleep health among adults.
Dr. Aric Prather will present novel findings linking measures of sleep quality, duration, and disturbances with measures of the speed of aging, including methylation and MRI-based aging clocks, using data from the Dunedin Study, UK Biobank, and ADNI cohorts. Opportunities to leverage multidimensional sleep health in future analyses will also be discussed.
Dr. Daniel Buysse, the chair and discussant of the session, will summarize key findings and reflect on the evolution of sleep health research over the last decade. He will highlight key advancements, challenges, and opportunities in the field.

Overall, this symposium brings together contemporary efforts to advance our understanding of how multidimensional sleep health relates to diverse age-related outcomes. By showcasing cutting-edge research, this session will highlight sleep health as a vital marker of resilience and healthy aging, underscoring its significant implications for public health and policy.
