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?

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.
The danger here is getting your sleeping bag wet. But yeah, if you can cuddle up to your piss jug.
