Being cold doesn't just make you uncomfortable, it also keeps you distracted since much of your energy is concentrated on trying to stay warm.
On the flip side, when we are warm we aren't just more productive, but we are also happier.

The solution, then, would be to keep a close eye on the thermostat. If you work in an office in which the thermostat is regulated, bring your own space heater with you. You'll not only be more comfortable, you'll be able to maximize your productivity and possibly even save yourself hours of work time.
