Yeah, mostly just a thing I've been doing since I was a kid, but I've been paying a lot of attention to breathing lately (blood pressure...) and I get notably less negatives sitting at a computer if I'm humming along to music. If I just sit here silently, I often notice cold hands/feet and a blood pressure spike. Often associated with intermittent sighs or irregular breathing. Humming just forces me to breathe. I can't keep humming if I don't have air, and it's a good regulator to keep me breathing without having to really think about it.
