Is There a Certain Temperature For a Workspace That Encourages Productivity?

It’s been quite cold in my location for the past week, so I’ve been working from home. I’ve noticed that when my toes are warm I work well and when they’re cold I don’t. However, I don’t feel productive if my living room is too warm. Does anyone know what particular temperature is best for productivity? Or am I just a Goldilocks in the sense that I want it to be “just right”?
