At low ambient temperatures, the body must produce more heat than at warmer temperatures, just to maintain a stable core temperature.  With time, the metabolic rate of animals continuously exposed to the cold will increase gradually without any increase in muscle activity.  This is termed '''non-shivering thermogenesis''' and is primarily attributed to:
