High Temperature Kills Productivity | Future IQ

High temperatures silently destroy human productivity. When the body overheats, we think slower, make more mistakes, lose focus, feel more tired, and even sleep worse and studies from offices, classrooms, and factories consistently show this effect across the world, including India. This is why Lee Kuan Yew once called air conditioning one of the most important inventions in history and even credited it as a major reason behind Singapore’s success. According to him, cooling made development possible in tropical countries. But this story is not just about ACs it is about how cooling shapes human performance itself. Better ventilation, shading, fans, building design, hydration, lighter clothing, and smarter urban planning can all improve productivity in hot climates. In a future where temperatures keep rising, staying cool may become one of the biggest economic advantages a country can have.
