When Heat Enters the Workplace, Productivity Pays the Price

Imagine a woman stitching clothes from a small Delhi home. Outside, temperatures are soaring. Inside, there is little ventilation, unreliable electricity and no affordable cooling. She cannot simply stop working her family depends on her income. WIEGO’s 2025 survey of 328 women home-based workers found that 84% reduced working hours due to heat, while 88% reported lower productivity. This is not just a climate problem. It is an economic productivity challenge. Research from India and abroad suggests that better workplace cooling, adequate rest, hydration and improved lighting can help workers remain productive. India has also expanded its heat action plans, but funding, implementation and access remain critical challenges. As India faces rising temperatures, demand for energy-efficient cooling, thermal management and electrical infrastructure could increase across homes, factories and commercial buildings. One company to understand in this theme is Blue Star Ltd.

, which operates in the air-conditioning and commercial refrigeration industry. Growing cooling requirements could create business opportunities, although profitability will depend on competition, input costs, energy-efficiency regulations and consumer demand. The bigger lesson? Heat resilience is not merely about comfort. It connects climate adaptation, labour productivity, infrastructure investment and business opportunities. Heat adaptation can protect worker productivity, while efficient cooling may create business opportunities; actual outcomes depend on affordability, execution and demand. Study how rising temperatures influence cooling demand, energy consumption and corporate earnings before drawing investment conclusions.
