Harvard Researchers Expand Study on Heat’s Impacts on Human Health and Livelihoods

Climate projections indicate that South Asia will face an increasing number of extremely hot days, posing severe direct and indirect threats to human health and livelihoods. However, traditional temperature measurements—whether from weather stations or satellites—fail to capture the localized effects of extreme heat. Enter the Community Heat Adaptation and Treatment Strategies (CommunityHATS) study, an initiative that follows hundreds of women working in the informal economy across a variety of indoor and outdoor environments in South Asia. Led by researchers from Harvard, in collaboration with the Self Employed Women’s Association (SEWA) in India, the Centre for Advanced Research in Building Science and Energy (CRDF) at CEPT University, Ahmedabad, and the All India Disaster Mitigation Institute, the study continuously monitors temperature and humidity around the clock for 13 months to provide a granular understanding of how extreme heat and humidity are truly experienced at the community level.
