When muscles contract, they burn calories, which in turn generates heat. It's one of the body's natural defenses against the cold.

The body's natural reaction to the cold is shivering. The body needs to keep at a certain level or else organs might not function properly. Shivering makes the muscles move causing them to produce heat to keep the body warm. Having fats also keeps the body warm as they block out the cold and provide energy for the muscles to keep warm by shivering.

Shivering is one of the methods that the human body uses to warm itself. It is a neurological reaction, that the body executes when it gets too cold. Joggers are familiar with the concept of moving to stay warm; they run in the coldest of weather and manage to stay warm.
Basic physics dictate that energy taken from a storage source (like our fat) and changed to another form of energy (your body movements), results in yet another form of energy - heat. So when your muscles start moving back and fourth rapidly, they make heat, which helps warm the body in the cold. Some people have a different tolerance for cold, and in fact those who shiver easier, can withstand colder temperatures. Specific tolerances can change as we adapt over long term exposure, which is why all those Florida natives look at you funny when you wear your shorts down there in January, they have just adapted to the warm temperatures.

We shake because that helps us to warm up.
