Extreme heat events are putting Indian workers at risk, prompting cities to implement heat-action plans and longer-term adaptation measures.

These temperature spikes threaten the health and income of the labor force, particularly those in manufacturing and outdoor roles. Because climate change is making heatwaves more frequent and intense, the risk extends beyond individual health to the stability of the broader economy.

Severe heat waves have been hitting India since April 2026 [3]. Temperatures have topped 40°C in several areas [1], with forecasts indicating continued heatwaves for the north and west of the country through June 2026.

In cities like Delhi, government authorities are racing to adapt. Current efforts include the rollout of heat-action plans designed to protect vulnerable populations from heatstroke and exhaustion. However, the scale of the crisis is vast, with heatwave risks affecting 38 crore, or 380 million, lives [2].

Workers in the manufacturing sector and those performing manual labor outdoors are the most exposed. For these individuals, the extreme heat creates a direct conflict between maintaining their health and securing their daily wages. While immediate cooling measures provide temporary relief, experts said that structural changes are necessary to protect the workforce.

Authorities are currently weighing more permanent adaptation strategies to mitigate the impact of rising temperatures. These include modifying work hours, and improving urban infrastructure to reduce the heat-island effect in densely populated cities.

“Heatwave risk affecting 38 crore (380 million) lives and the economy”

The intersection of extreme climate events and a large outdoor labor force creates a systemic economic vulnerability for India. By affecting 380 million people, these heatwaves are no longer just public health emergencies but are significant threats to national productivity and labor stability, necessitating a shift from reactive emergency plans to permanent urban and industrial restructuring.
