Is it me or do quite a lot of people create what I call “fake stress”?

I see it a lot in day to day life as what I see as a coping mechanism for most people. People love to act busy which in turn creates mental stress for them but quite often it is for the simplest tasks that require little to no stress at all. What is this coping mechanism for?
Worrying and stressing over things that require no stress has to be some kind of disorder. I’m sure we all know people like this but I am yet to find out why people do this. There’s no benefit to it.
I’m sure it must have some link to school life when we get taught deadlines, tasks and completing things in time. But this fake urgency and fake stress I see is a very common occurrence I cannot get my head around.
Is there any studies on this?
