A rise in temperature will lead to a decrease in labor productivity (more dehydration, chronic health diseases and even death) which will further leading to a decline in economic activity. A critical factor to curtail losses in work capacity will be the extent of application of preventive strategies (such as cooling technologies, hydration, and work rotation) in outdoor and indoor work environment. Policy reforms should include long-term and short-term measures to mitigate the impact of heat on workers’ productivity. Long-term measures like reducing greenhouse emissions and short-term measures like providing clean drinking water at the workplace, good air conditioning, shade cover, and utilizing green architects to capture natural air and light.
