If we stop, we don't earn. And if we don't earn, the family doesn't eat.
Beneath Delhi's scorching skies, where temperatures routinely exceed 45 degrees Celsius, nearly 90 percent of India's workforce labors without contracts, safety nets, or the luxury of rest — because for them, stopping work means not eating. These informal workers — rickshaw drivers, street vendors, domestic cleaners — inhabit a cruel paradox: the very survival that compels them outdoors is being slowly eroded by the heat they cannot escape. As climate scientists warn that temperatures are approaching the outer limits of human tolerance, the question being forced into the open is not merely one of public health, but of who bears the cost of a warming world.
- Daily temperatures above 45°C are pushing human bodies toward their physiological limits, with workers reporting their bodies 'shutting down' mid-task yet unable to stop.
- Missing even a single workday costs informal workers $5–7 in lost wages — a sum that directly threatens rent, food, and family survival with no safety net to absorb the loss.
- Hospitals are treating rising waves of dehydration, kidney stress, and heat exhaustion, while workers ignore early warning signs like dizziness and confusion because stopping is not an option.
- At night, tin-and-plastic homes trap the day's heat, preventing bodies from recovering during sleep and compounding exhaustion into a dangerous, accumulating debt.
- Government advice to 'stay hydrated and rest' lands hollow for millions whose poverty removes the very choice such guidance assumes they have.
Inside Delhi's markets, the divide is visible and immediate. Behind air-conditioned glass, shoppers browse at leisure. Outside, in heat that regularly crosses 45 degrees Celsius, street vendors, rickshaw drivers, and domestic workers remain at their posts — because for nearly 90 percent of India's workforce, the informal economy offers no contracts, no security, and no days off without consequence.
Harish Chandra, 52, pedals a cycle-rickshaw through Delhi's congested streets each day, feeling his body falter under the midday sun but unable to stop. He has sent his wife and children back to their village in Bihar, though temperatures there are no gentler. For workers like him, summer has become less a season than an annual fight to stay alive and solvent.
Climate scientists have documented a troubling shift: India's heat seasons are growing longer and more severe. Dr. Soumya Swaminathan, former chief scientist at the WHO, warned this week that recorded temperatures are approaching the outer limits of what human physiology can endure. Delhi's urban heat island effect — concrete, traffic, and scarce greenery — amplifies this danger further.
Mohammad Umar, 50, was forced home last week when his heart raced and his strength gave out entirely. He bathed five times that day just to remain conscious. But the absence cost him 500 to 700 rupees — money subtracted directly from savings while rent and food waited for no one. The ILO projects that heat stress could cut India's total working hours by 5.8 percent by 2030, with outdoor laborers bearing the heaviest burden.
Doctors describe the toll with clinical clarity: dehydration, low blood pressure, kidney stress, heat exhaustion — conditions that become emergencies when workers ignore early signs of dizziness, nausea, and confusion because they cannot afford to heed them. The danger continues after dark. Homes built from tin and plastic absorb heat all day and release it through the night, denying bodies the recovery that sleep is meant to provide.
Sanjeeda, 40, a widow who cleans homes and rooftops to support her children, was bedridden for days in mid-May with severe headaches and fever. Some days she scrubs marble floors that feel like they are burning underfoot. Her employers sometimes offer water or a fan. But the work must be done regardless. When the Prime Minister posted advice urging people to stay hydrated and watch for heat exhaustion, it reached millions for whom such choices do not exist. The heat does not pause for survival — and survival, for now, cannot pause for the heat.
Inside Delhi's markets, the contrast is stark and immediate. Behind glass doors and air-conditioning units, shoppers browse leisurely. Outside, under a sun that has climbed past 45 degrees Celsius, street vendors, rickshaw drivers, and fruit sellers remain at their posts, sweat-soaked and exhausted. For them, the choice between comfort and survival was made long ago. Nearly 90 percent of India's workforce operates in the informal economy—no contracts, no job security, no safety net. Most depend on outdoor work for daily wages. Stepping away from the heat is not an option they can afford.
Harish Chandra is 52 and pedals a cycle-rickshaw through Delhi's congested streets. His workday begins around nine in the morning, when the temperature is still manageable. By noon, the sun becomes punishing. He describes the sensation of his body shutting down as he pedals, the physical sensation of giving up. But stopping means no income. No income means his family does not eat. Recently, he sent his wife and three children back to their village in Bihar, hoping the open spaces there would offer easier conditions than Delhi's cramped neighborhoods and narrow lanes, even though temperatures there are equally severe. For workers like Chandra, summer has transformed from a season into an annual battle for survival.
The heat season in India typically runs from April through early July, when monsoon rains finally arrive. But climate scientists have documented a troubling shift: extreme heat is becoming longer, harsher, and more unpredictable as global warming intensifies heatwaves across South Asia. Dr. Soumya Swaminathan, former chief scientist at the World Health Organization, warned this week that temperatures now being recorded in India are approaching the outer limits of what human bodies can tolerate, threatening both lives and livelihoods. Since mid-May, Delhi and surrounding areas have recorded daily temperatures above 40 degrees Celsius, frequently crossing 45 degrees in the afternoon. Cities like Delhi face particular vulnerability because of the urban heat island effect—concrete, traffic congestion, and sparse green cover trap heat and keep urban areas significantly hotter than surrounding regions.
Mohammad Umar, 50, sits inside his tuk-tuk near a busy traffic signal, waiting for passengers. He rarely takes days off, but last week the heat finally forced him to stay home. His heart was racing. His body had no strength. He bathed five times that day just to remain conscious. But missing work carries a steep price: a single absent day costs him 500 to 700 rupees, roughly five to seven dollars. That money comes directly from his small savings, even as rent and food must still be paid. The International Labour Organization estimates that heat stress could reduce India's total working hours by 5.8 percent by 2030, with outdoor workers in agriculture and construction facing the worst impacts.
Doctors describe the physiological toll with clinical precision. Prolonged exposure to extreme heat strains the body severely, especially for people spending long hours outdoors without shade, cooling, or adequate hydration. Dr. Satish Koul, principal director of internal medicine at Fortis Hospital Gurgaon, notes that hospitals routinely treat cases of dehydration, low blood pressure, kidney stress, and heat exhaustion during extended heatwaves. Early warning signs—dizziness, weakness, headache, nausea, confusion—are often ignored by workers who cannot afford to stop. If someone stops sweating, becomes disoriented, or collapses, the situation becomes a medical emergency. But the danger extends beyond working hours. Much of Delhi's informal migrant workforce lives in densely packed settlements with unreliable electricity, poor ventilation, and no air-conditioning. Homes constructed from tin sheets and plastic absorb heat throughout the day and release it slowly through the night. When the body cannot cool properly during sleep, exhaustion accumulates day after day, preventing recovery.
Sanjeeda is 40, a widow who has worked in factories, small shops, and private homes to raise her children. In mid-May, she was bedridden for days with severe headaches and fever after heat exposure. The sun feels harsh from morning onward. By the time she reaches the houses where she works as a cleaner, her clothes are already soaked. Some days she must clean rooftops where marble floors feel like they are burning. Her employers occasionally offer water, lemonade, or a place to sit in front of a fan. But regardless of the temperature, the work must be done. She has no alternative. The Prime Minister posted on social media urging people to stay hydrated, carry water outdoors, and watch for signs of heat exhaustion. But such advice assumes a choice that does not exist for millions. Rent must be paid. Food must be bought. The heat does not pause for survival.

The body gives up. My day starts around nine in the morning, when the weather is still manageable. But by noon, it becomes difficult. The sun is so harsh that sometimes I feel my body giving up while I pedal.— Harish Chandra, 52-year-old cycle-rickshaw driver
Temperatures now being recorded in India are approaching the limits of human tolerability and pose a threat to both lives and livelihoods.— Dr. Soumya Swaminathan, former chief scientist at the World Health Organization
La Conversación del Hearth Otra perspectiva de la historia
Why do these workers stay outside when the heat becomes dangerous? Can't they simply find shelter or take breaks?
Because a day without work means a day without food for their families. A single absent day costs them five to seven dollars—money they need for rent and meals. The choice isn't really a choice at all.
But surely there are warnings from the government, from doctors? Doesn't anyone tell them to stop?
Yes, there are warnings. The Prime Minister himself posted about staying hydrated and watching for heat exhaustion. But advice to rest assumes you have savings, or that someone else will feed your children. These workers don't have that luxury.
What happens to their bodies when they work in this heat day after day?
The exhaustion compounds. They can't cool down properly at night because their homes are built from tin and plastic that trap heat. So the strain builds—dehydration, kidney stress, confusion, sometimes collapse. Doctors see it as a medical emergency, but for the worker, it's just another day.
Is this getting worse?
Yes. Climate scientists say extreme heat is becoming longer and harsher. The International Labour Organization projects that heat stress could reduce India's working hours by 5.8 percent by 2030. And temperatures are now approaching what experts call the limits of human tolerability.
