Body Temp changes when playing

[AceofSpades]

I've noticed a trend that is common when I am playing in a tournaments. I play good solid poker, but then after a while, I start making really dumb or bizarre plays and get overcommitted to trying to win pots without really any hand. In other words I spew chips rapidly. Usually when this happens I am really hot, flushed in the face and maybe a mild sweat. I'm wondering if my bad play/poor decision making is related to the temperature change in my body. Does anyone do this/have any idea why this is happening?

I actually measured my temp immediately after busting out in this manner and it was 99.2 f, about 10-15 mins later it was 98.6.

Any Thoughts?
