Warm workers work better, an ergonomics study at Cornell University finds. Chilly workers not only make more errors but cooler temperatures could increase a worker’s hourly labor cost by 10 percent, estimates Alan Hedge, professor of design and environmental analysis and director of Cornell’s Human Factors and Ergonomics Laboratory. When the office temperature in a month-long study increased from 68 to 77 degrees Fahrenheit, typing errors fell by 44 percent and typing output jumped 150 percent. Hedge’s study was exploring the link between changes in the physical environment and work performance.
