Oh, this is a fun (deep-fried sarcasm here) thing to have, ask me how I know. It's not well researched, but apparently what you (or actually we) are feeling is a fight-or-flight response. I started using it to gauge whether I'm upset with a particular person over something, because it would intensify in such cases, and reflect on that. Also helped my friend manually remove breath and lip sounds from a recording he was doing for an indie mod for a game because, well, with enough compression it was painful to listen to for me.
