It's a natural response to the cold that may be related to protecting the body against frost bite. As the body purges itself of water, the freezing point of the remaining in your body water lowers. This is why pouring salt on the driveway can help prevent it from freezing over--the amount of impurities changes the freezing point.
Amazingly enough, there's a lot of research around this because it may also give clues to why people who have ancestors from cold climates have a higher Type II Diabetes rate than people from warmer climates. It may be related to a survival system that is now working against us in a world where food is easy to come by and we're not in danger of freezing to death all the time.
