One day of extreme heat causes 3,400 excess deaths across India, study estimates
A recent study estimates that a single day of extreme heat in India results in approximately 3,400 excess deaths. The research highlights the significant mortality impact of heatwaves, particularly in economically disadvantaged states. It calls for targeted federal investment in heat resilience strategies to address the disproportionate burden faced by these regions.
- ▪A single day of extreme heat causes about 3,400 excess deaths across India.
- ▪A five-day heatwave is estimated to result in nearly 30,000 excess deaths.
- ▪Uttar Pradesh accounts for about 8,100 excess deaths during a five-day heatwave.
- ▪The study emphasizes the need for federal adaptation investment in high-burden, low-GDP states.
- ▪The top 100 districts, representing nearly one-third of India's population, account for 44 percent of excess deaths during a five-day heatwave.
