Tamil Nadu heat-stress health study to build personalised risk tool across Chennai and Mayiladuthurai sites
A Tamil Nadu-Karnataka study will assess heat stress on physical and mental health and develop a personalised heat-risk tool.
Key highlights
Direct fact
In July 2026, a study led by the M.S. Swaminathan Research Foundation (MSSRF) began in Tamil Nadu and Karnataka to measure how heat affects physical and mental health and to build a personalised heat-impact metric for individuals, homes and communities.
Key specifics
- Study partners include MSSRF, the State governments, SCARF, the Indian Institute of Science, Bengaluru, and ICMR institutions.
- Tamil Nadu sites are Perungudi in Chennai and Poompuhar in Mayiladuthurai; Karnataka sites are Sirwar in Raichur and Chalakarre in Chitradurga.
- Each site will involve 1,200 households, and 80 residents will receive a digital watch to track surface body temperature.
- Two weather systems at every site will measure environmental temperature, pollution, air quality and humidity.
- The study will monitor vitals and salivary cortisol, and it aims to develop an early warning app with location-based heat-risk prediction.
