In a rapidly aging population, understanding the factors that contribute to cognitive health has become increasingly important. This research study focuses on the association between the time spent on sleep and self-care activities and cognitive functioning among individuals aged 45 and above in India, utilizing data from the World Health Organization's Study on Global Aging and Adult Health (WHO SAGE) India wave-2 conducted in year 2015. The univariate, bivariate and multivariate analysis have been carried out for the fulfillment of the study’s objectives. The results form linear regression models suggest that the more time spend on the domestic household work and care giving activates were significantly negative associated with the cognitive functioning. The time (hours) spend on the paid work activity is mildly associated with the cognitive score.
