The NIHR Global Health Research Centre for Non-Communicable Disease And Environmental Change (GHRC-NCD EC) has been researching the linkage between heat and health since 2010, with a special focus on occupational health, but not barring community well-being. This sustained effort was crucial to generate the needed evidence to bring to light the adverse effects of extreme heat, especially in an already tropical country like India, where heat is perceived as “natural”. The need to generate evidence to design feasible and sustainable interventions, policy changes, and prepare ourselves for a hotter world is of paramount importance.
