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?

This is the right answer. To add to this; you produce more urine when you’re cold for this very reason. When you have to go, you have to go. But try to stay in your tent and piss in an empty bottle, then cuddle up to that bottle when it’s still warm. You get the best of both worlds.
