摘要:Rising temperatures are causing distress across the world, and for those most vulnerable, it is a silent killer. Information about indoor air temperature in residential dwellings is of interest for a range of reasons, such as health, thermal comfort and coping practices . However, there have been only few studies that measure indoor heat exposure, and contrast these to outdoor temperatures in rural- urban areas, of which none are in South Asia . We aim to close this knowledge gap with our indoor and outdoor heat measurement dataset, covering fve low-income sites in South Asia . Two sites are in rural areas (Maharashtra, India), while three sites focus on urban areas (Dhaka, Delhi and Faisalabad) . Data are based on 206 indoor temperature data loggers and complemented by data from fve outdoor automated weather stations . The data-set can be used to examine temperature and humidity variation in low-socioeconomic status households in rural and urban areas and to better understand factors aggravating heat stress . This is important to plan and implement actions for combating heat stress .
