India’s heatwaves kill 3,400 in a single day: Study

ISLAMABAD - India is among the world’s most heat-exposed nations, with a single day of severe heat potentially causing about 3,400 deaths and a five-day heatwave causing nearly 30,000 deaths nationwide, according to the academic journal Frontiers in Environmental Health. The peer-reviewed study, authored by Piyush Narang and Ashok Gadgil of UC Berkeley’s Goldman School of Public Policy, said official heat-related death figures capture only a fraction of the true toll. The all-India heat-related excess mortality reported in the press and by government agencies remains about 800 per year, meaning a single extreme day kills more than four times what officials count across an entire year, according to the journal. “Heat mortality remains substantially undercounted,” the study said, adding that many deaths triggered or worsened by extreme temperatures are often recorded under other medical causes rather than heat exposure itself.

Uttar Pradesh alone was estimated to account for more than 8,000 excess deaths, followed by Bihar (3,615), Madhya Pradesh (2,964), Rajasthan (2,664), and Gujarat (2,354). According to the study, these five states together hold 43% of India’s population but account for more than 60% of the projected national heat mortality.
