It turns out 77 degrees Fahrenheit (25 degrees Celsius) is most conducive to high productivity work according some research done by the Cornell University.
"At 77 degrees Fahrenheit, the workers were keyboarding 100 percent of the time with a 10 percent error rate, but at 68 degrees, their keying rate went down to 54 percent of the time with a 25 percent error rate," Hedge says. "Temperature is certainly a key variable that can impact performance."
Now, before you reach to your A/C to adjust to your temperature, be advised - there is this other study by the Helsinki University of Technology that says the ideal temperature might be closer to 71 F (22 C) - progressively getting worse before and after reaching that temperature.
Now you go.
