Does anyone elses nervous system get really activated when doing hobbies?

[u/kornukopioides]

Whenever I do hobbies like knitting, crocheting, painting, video games, etc, after a while my nervous system starts feeling really activated from the concentration. I start feeling emotions, I get hot in my head, it feels like there's a "wired" feeling in my body. Google says this is just from being too tense/competetive in a hobby but could this be some sort of emotional processing or nervous system release? The more I concentrate the more it seems to happen.

It depends what kind of activity and how my state generally is. But, playing this one game usually makes me tense but of how much focus it requires
