Extreme heat is sweeping across India, with temperatures in some regions reaching 46°C [1] and approaching 50°C [4].
The crisis creates a critical public health risk for millions of citizens. Daily-wage earners, such as rickshaw drivers and porters, are particularly vulnerable as they must work outdoors during peak thermal stress.
In New Delhi and various northern states, the heat has reached dangerous levels [2]. New Delhi recorded a temperature of 43.8°C, marking the hottest day of the season [3]. The intensity of these heatwaves is contributing to a significant mortality rate, with heat-related illnesses killing over 150,000 people in India each year [2].
Experts said a combination of rapid urbanization and broader climate-change trends are the primary drivers of the rising temperatures. In New Delhi specifically, temperatures have risen by nearly three degrees over the past decade [5]. This trend reflects a broader pattern of warming that makes traditional summer seasons increasingly lethal.
Local infrastructure and urban planning have struggled to keep pace with these shifts. The lack of cooling centers and the prevalence of "urban heat islands" mean that those without access to air conditioning face an escalating threat to their survival, especially as temperatures continue to climb toward 50°C [4].

The increasing frequency and intensity of Indian heatwaves demonstrate the compounding effect of global warming and local urban growth. As cities like New Delhi experience rapid temperature climbs, the economic burden falls heaviest on the informal labor sector, where work cannot be moved indoors. This creates a cycle where the most economically vulnerable populations are also the most physically exposed to lethal environmental conditions.
