Why do we unconsciously do things like spinning a pen or biting nails when we try to concentrate?


Why does our brain partly do something else at the same time and not even consciously?

I think everyone’s mind works differently. But a repetitive motion helps balance a person’s mind. If a person is under-stimulated like tired or bored, then this can stimulate them. If a person is over-stimulated, then this can calm them. And thus help them concentrate and work out a problem. Most times they aren’t even aware.

It can also be a sign of anxiety, stress or a person feels impatient. Usually when waiting. If a person is in a relaxed mind-set like after meditating, they won’t feel the need to do this.
