When your body is exposed to cold, it requires more heat to warm you up. To do so, it has to process more energy and, in doing so, helps you burn more fat, more efficiently. It can also activate “brown fat”, which is a sort of good fat that helps generate heat, increase your metabolism and burn fat.
