  Exploring the determinants of health and maintaining and enhancing the health capital of the elderly is key to addressing ageing and its derivatives in China. Exploring the determinants of health in the elderly and maintaining and enhancing the health capital of the elderly is key to addressing ageing and its derivatives in China. This article sought to investigate the longitudinal association between sleep duration and cognitive function in Chinese elderly. Its marginal contribution is the discussion of the effects of sleep duration on different domains of cognitive function. There is an inverted U‐shaped relationship between sleep duration and global cognition and cognitive domains, with the highest cognitive scores observed for sleep durations between 6 and 9 h. These findings suggest the need for intervention measures to maintain healthy sleep durations among Chinese elderly people.
