As temperatures in Delhi consistently climb past 45C, a stark divide has emerged between those who can retreat into air-conditioned spaces and the millions of informal workers who remain exposed to the elements. For street vendors, rickshaw pullers, and construction laborers, the extreme heat is not merely an environmental challenge but a direct threat to their survival. With nearly 90% of India’s workforce operating without contracts or job security, many feel they have no choice but to continue working through the peak of the afternoon to ensure their families can afford basic necessities.

Climate experts note that heatwaves in South Asia are becoming increasingly frequent and intense, exacerbated by the ‘urban heat island effect’ where dense concrete and limited green space trap heat within the city. While government initiatives and heat action plans have been introduced to provide cooling centers and public advisories, these measures often fail to reach those who must remain mobile to earn a daily wage. The economic pressure is immense; missing a single day of work can result in a significant loss of income, forcing many to endure physical symptoms of heat exhaustion, such as dizziness and severe dehydration, just to maintain their livelihoods.

The health risks extend beyond the workday, as many migrant workers return to cramped, poorly ventilated settlements constructed from materials like tin and plastic that retain heat throughout the night. Medical professionals warn that this lack of overnight recovery leads to a dangerous accumulation of heat stress, which can result in long-term kidney issues, cardiovascular strain, and acute medical emergencies. Despite the clear dangers, the necessity of daily earnings continues to outweigh the risks for a vast segment of the population, turning the summer season into a grueling test of endurance.
