As global temperatures climb, the fashion industry finds itself at the epicenter of an unacknowledged humanitarian crisis. Heat stress which is the condition where the body cannot maintain a safe temperature due to prolonged exposure to high heat and humidity, is now one of the most dangerous and underreported threats facing garment workers. It can lead to dehydration, heatstroke, organ damage, and even death. While climate reports focus on emissions and decarbonization targets, workers across India, Turkey, and China are quietly enduring another brutal summer.
When The Fashion Factory Floor Becomes the Frontline of Climate Impact
In 2023 India experienced a searing heat wave, during which parts of the country reached more than 49°C (120°F). Turkey recorded its hottest summer ever in 2024, with temperatures exceeding 40 °C (104°F). Yet the industry’s demands did not pause and factory lines moved on, orders were fulfilled, and deadlines met.
The dominant logic of global supply chains is often referred to as the “race to the bottom” and it pushes brands to seek the lowest costs, cascading pressure down to suppliers and ultimately to the workers. That pressure manifests not just in low wages or excessive hours, but in an unrelenting demand for productivity, even as factories become furnaces. When workers are expected to perform under conditions that cause dehydration, fainting, and long-term illness, it is not just discomfort, but a form of abuse.
“Heat isn’t just a climate issue,” notes activist Nandita. “It’s a growing public health crisis, driven by fashion brands’ relentless pursuit of profit at any cost.”
The fashion industry’s sustainability rhetoric has climate pledges and carbon neutrality claims and often fails to account for human cost. Research from Politecnico di Milano in collaboration with the Tamil Nadu Textile and Common Labour Union reveals that operational efficiency and cost-cutting practices have made conditions worse, not better, for the people at the bottom of the chain. These are not unfortunate side effects; they are unfortunately baked into the model.
“Most of my members can’t even afford to buy a small fan during a heatwave,” says Thivya of TTCU. “We’ve had workers faint on the shop floor during 43–45°C heat. Still, brands refuse to involve unions or listen to workers when designing solutions.”
Sustainability Must Extend Beyond Emissions to Include People On Fashion Frontlines
Workers, especially women in the Global South, are bearing the brunt of both climate breakdown and economic exploitation, yet their voices remain excluded from strategy meetings and ESG panels. Unions are dismissed as “non-experts,” and the systems of accountability which include third-party audits, rarely engage them directly.
“Dear fashion executives and policy makers,” urges Dr. Hakan Karaosman, “let’s leave your air-conditioned offices and go to the factories… We cannot tackle heat stress with top-down interventions.”
If climate action continues to ignore labor conditions, it is not just incomplete as garment workers are not just casualties of warming, they are a part of the warning system.
Heat stress is an urgent reminder that climate resilience in the fashion industry must include the people who make its products. As global temperatures rise, protecting worker wellbeing can no longer be viewed as separate from environmental goals. Addressing heat stress through inclusive strategies and worker-informed solutions is not just a matter of ethics, but of long-term sustainability. A truly responsible industry is one that values both the planet and the people behind the clothes.
