India faces increasingly severe heatwaves each year, with temperatures regularly crossing 45°C in several states during summer months. While the country has made strides in developing Heat Action Plans (HAPs) since the deadly 2010 Ahmedabad heatwave, experts argue that these initiatives still miss critical public health components that could save lives and reduce heat-related illnesses.
The Gap Between Plans and Public Health Reality
Heat Action Plans were introduced in India to reduce mortality and morbidity during extreme heat events. Cities like Ahmedabad pioneered these efforts, creating early warning systems and awareness campaigns. However, the implementation across the country reveals significant shortcomings in addressing heat as a serious public health threat.
Most HAPs focus heavily on issuing heat alerts and advisories through traditional media and increasingly through mobile apps. While awareness is important, the plans often lack robust mechanisms to ensure vulnerable populations actually receive timely warnings and can act on them. Daily wage labourers, outdoor workers, homeless individuals, and those living in informal settlements frequently remain unreached by these communications.
Missing Infrastructure for Heat Protection
A major flaw in India's heat response is the absence of adequate cooling infrastructure accessible to all citizens. Public health logic demands that when temperatures become dangerous, people need safe spaces to cool down. Yet most Indian cities lack a network of publicly accessible air-conditioned cooling centres where people can take refuge during peak heat hours.
The few cooling centres that do exist are often limited in number and poorly publicised. Rural areas are even more underserved, with minimal infrastructure beyond natural shade. This stands in stark contrast to heat response systems in countries like the United States, France, or Australia, where cooling centres are a standard component of heat emergency plans.
Healthcare System Preparedness
India's healthcare facilities themselves are frequently unprepared for the surge in heat-related illnesses during summer. Many primary health centres and district hospitals lack protocols for recognizing and treating heat exhaustion and heat stroke quickly. Staff training on heat illness management remains inconsistent across states.
Emergency departments often see delays in cooling treatment for heat stroke patients, partly due to lack of equipment like cooling blankets or ice baths, and partly due to insufficient awareness about the urgency required. Every minute of delay in cooling a heat stroke patient increases the risk of permanent organ damage and death.
Vulnerable Populations Left Behind
The groups most at risk from extreme heat include outdoor workers, children, elderly people, pregnant women, and those with chronic illnesses. Yet HAPs rarely include targeted interventions for these populations.
Construction workers and agricultural labourers continue working through peak afternoon hours without enforceable heat safety regulations. While some states recommend work restrictions during extreme heat, these remain advisory rather than mandatory, and compliance is minimal. There are no widespread programs to provide these workers with cooling vests, adequate hydration stations, or shaded rest areas.
Data Collection and Monitoring Weaknesses
Effective public health response requires robust data on heat-related mortality and morbidity. India's current system significantly underreports heat deaths. Death certificates rarely list heat as the cause of death, even when it is a contributing factor. This underreporting makes it difficult to assess the true burden of heat illness and to allocate resources appropriately.
Many states lack real-time syndromic surveillance systems that could track spikes in heat-related hospital admissions, helping authorities respond quickly to emerging heat emergencies in specific areas.
Coordination Challenges
Heat response requires coordination across multiple departments including health, urban development, labour, power, and water supply. In practice, these departments often work in silos. Health departments may issue warnings, but if the power supply department cannot ensure stable electricity for cooling, or if water supply is insufficient for hydration and cooling purposes, the response remains incomplete.
The Path Forward
Strengthening India's heat response demands treating heat as the public health emergency it truly is. This means investing in cooling infrastructure, enforcing occupational heat safety standards, training healthcare workers, improving data collection systems, and ensuring coordination across government departments. Climate change will only intensify heat challenges in coming years, making these improvements increasingly urgent.
The evidence is clear that heat kills and sickens people across India every summer. The question is whether policymakers will prioritise public health logic in crafting responses that actually protect the most vulnerable when temperatures soar.
