Heatwaves in India have caused over 20,000 deaths between 1992 and 2015, with 2,422 fatalities in 2015 alone. Vulnerable populations, including outdoor workers, children, and the elderly, face heightened risks of heat-related illnesses such as heat exhaustion, dehydration, and heat stroke. Urban areas are particularly affected due to the Urban Heat Island effect, which exacerbates nighttime temperatures and limits recovery from daytime heat exposure.
