Cooling Doctrine – India’s Structural Response to Extreme Heatwaves

Moving Beyond Short-Term Fixes

India’s battle against extreme heat is shifting from reactive measures to a structural approach. For over a decade, recurring heatwaves have exposed the inadequacy of routine guidelines and temporary interventions. Annual advisories from the National Disaster Management Authority (NDMA) often replicate the same measures—water kiosks, shaded bus stops, and stay-at-home instructions—without addressing the deeper vulnerabilities of workers exposed to relentless heat.

Cooling as a Public Right

The proposed National Cooling Doctrine reframes cooling as a basic entitlement and public health necessity, not a luxury.

• Workplace Standards: Minimum cooling requirements must be mandated for factories, warehouses, kitchens, and offices.

• Strict Enforcement: Inspections are essential to prevent non-compliance driven by cost-cutting.

• Biological Thresholds: Sustained body temperatures above 35°C impair human functioning, making cooling a matter of survival.

Structural and Indigenous Solutions

India must adopt both passive and technological innovations:

• Passive Cooling: White reflective roofs and heat-resistant building designs.

• Indigenous AC Systems: Energy-efficient models tailored to humid climates and unstable power supply.

• District Cooling Networks: Centralised cooling systems, as seen in Singapore and Dubai, for large-scale urban efficiency.

Policy and Financial Framework

The 16th Finance Commission, led by Arvind Panagariya, has recommended classifying heatwaves as a National Disaster. This would unlock central funding through the State Disaster Response Fund (SDRF) for heat management. Unlike floods or earthquakes, heat-related deaths often remain invisible, despite their devastating toll.

The Ahmedabad Heat Action Plan (HAP) offers a model of success. Developed after the deadly 2010 heatwave that claimed over 1,300 lives, it has since saved thousands and become a global benchmark for preparedness.

Conclusion

India must move from short-term heatwave responses to a comprehensive cooling strategy. Treating thermal safety as a matter of public health, labour rights, and urban governance is essential. With structural reforms, indigenous innovation, and dedicated funding, India can build resilience against one of its most silent yet deadly threats.
