Cold environments are stressful. They cause release of adrenaline in the brain and body. They also stimulate metabolism and fat loss by activation of thermogenenic mitochondrial action. **Whether cold exposure does one or the other depends on whether or not you allow or resist shivering.**

That is because cold induced shiver triggers the release of the molecule succinate. That in turn, activates brown fat (the “good” kind of fat), thermogenesis and white/pink fat loss. (Ref: nature.com/articles/s41586-018-0353-2?proof=t

Alas, just shaking or shivering doesn’t do the trick to activate brown fat thermogenesis. It has to be in actual response to cold.
