Summary
A large body of medical research has shown that sleep deprivation adversely affects outcomes ranging from cognitive function to pain sensitivity and cardiovascular function. Much of this evidence comes from sleep labs in the developed world, where sleep can be carefully manipulated, and short-run physiological and cognitive outcomes precisely measured. In contrast, there is much less knowledge about how sleep deprivation affects the health of individuals in the developing world, coming from a lack of studies outside the lab and over longer periods. This project aims to fill this gap. The investigators will implement a randomized controlled trial (RCT) with 450 low-income adults in Chennai, India, providing the first objective measurement of sleep in a developing country. The investigators will also evaluate scalable interventions to improve the sleep of poor adults, such as providing home sleep-aid devices and a comfortable space for a 30-minute afternoon nap at the participants' work site. Finally, the study aims to assess the impact of improved sleep on health, with a primary focus on cardiovascular health and cognitive outcomes.
