How to Survive Cold Temperatures

The body is pulling all of that heat into the core. It's not wasting any energy on extraneous things like fingers and toes. Don't need those if it's a life and death situation. What you need is your heart to survive, your organs to survive. And that's what your fight and flight system is doing. We're best to take that energy and survive. Where it becomes a problem is when this system is chronically firing over and over and over - chronic adrenaline fatigue.
