Sleep Capital: Linking Brain Health to Wellbeing and Economic Productivity Across the Lifespan.
Abstract
Sleep capital contributes to individual and societal wellbeing, productivity, and economic outcomes and involves a novel aspect of brain capital. It encompasses the quality and quantity of sleep as integral components that influence cognitive abilities, mental and brain health, and physical health, affecting workplace productivity, learning, decision-making, and overall economic performance. Here, we bring a framework to understand the complex relationship between sleep quality, health, wellbeing, and economic productivity. Then we outline the multilevel impact of sleep on cognitive abilities, mental/brain health, and economic indicators, providing evidence for the substantial returns on investment in sleep health initiatives. Moreover, sleep capital is a key factor when considering brain health across the lifespan, especially for the aging population.

Research summary
The paper discusses the relationship between sleep quality and various aspects of health and productivity, which can indirectly relate to longevity by emphasizing the importance of sleep for cognitive and physical health across the lifespan. However, it does not address the root causes of aging or propose mechanisms for lifespan extension. The findings may contribute to the understanding of health in aging populations, but the overall impact on the field of longevity research is limited.
