Why do people pace back and forth when they're thinking really hard about something?

I know I do this, and I start doing it without even thinking about it. Does it help you concentrate somehow?

I don't know if there is any literature on the subject out there, but one possible reason may be less about thinking and more of a physiological response to the stress or anxiety that comes along with it. We tend to use rocking or rhythmic patterns when trying to regulate. (You can look into research on stress regulation methods)

So it's not you think better, it helps you calm down which lets you think better.
