More than 100 people have died within three days in the southern Indian states of Andhra Pradesh and Telangana, as an intense heatwave pushed temperatures to dangerous levels and overwhelmed the capacity of communities to cope. The deaths, concentrated among outdoor labourers, the elderly and those without reliable access to cooling, underscored the rising human toll of the extreme heat that has become a recurring feature of the Indian summer.
The heat has driven electricity demand to record highs. As households and businesses ran air-conditioners and fans at full tilt, power consumption surged to an all-time peak, and parts of the country experienced cuts as the grid struggled to keep pace. The strain laid bare a vicious cycle in which hotter weather drives more cooling demand, which in turn taxes an electricity system still heavily dependent on thermal generation.
Southern India has borne the brunt of the current spell, but the phenomenon is national in scope. Successive summers have brought earlier, longer and more intense heatwaves to the subcontinent, with peak temperatures in some regions pushing past the thresholds at which the human body can regulate its own temperature, particularly when high humidity prevents the cooling effect of perspiration.
State authorities have issued health advisories urging residents to avoid the midday sun, stay hydrated and check on vulnerable neighbours, and have adjusted working hours and school schedules in the worst-affected districts. But the measures contend with the realities of an economy in which tens of millions work outdoors, in agriculture, construction and informal trades, with little choice but to endure the heat.
The episode has sharpened the debate over how India adapts to a warming climate. Public-health experts have pressed for heat-action plans that move beyond advisories to concrete provisions — shaded shelters, water points, cooling centres and enforceable limits on outdoor work during extreme spells — while energy planners weigh how to expand and harden a grid facing demand peaks that climb each year.
For now, the immediate priority is survival through the current spell. With temperatures forecast to remain elevated, officials in the affected states were bracing for further casualties, and the heatwave stood as a stark reminder that the costs of extreme weather fall first and hardest on those least equipped to escape it.
