No, well first off the measurement of temperature is terrible, very inaccurate and low resolution. In the second event, I have multiple things I want to measure and I can't derive stress from temp, I have adrenaline going on a lot of the time (more and more often than most, because of stress doing nothing), and then, whatever I've got going on...which also affects things. Then indoor heating, what I've eaten, what I'm wearing? No, much better to draw blood and take a litmus test, temperature is plain noise.
