How does excretion (defection or urination) affect the thermal energy of the body? The substance retains some thermal energy from the body, but does losing that substance cool the body in any way?

I don’t have an exact answer for you, but I can share this: Part of military training up here in the Arctic involves a lot of cold weather training. And an officer explicitly told us that if we felt the slightest urge to shit or piss, take care of it ASAP - “Heating up all that crap is energy better spent heating up the rest of you”
Additionally if you can collect it and position it next to your skin somehow you can extract some of the heat back to your body. Gotta be careful though, lest you get piss or shit on yourself.
