During the winter months the weather can turn frigid, cold and beyond freezing.
People become blobs of mismatched fuzzy wool.
Even hats, often accused of destroying hair styles are worn by those who wish to keep their ears from becoming crisp and snapping off. Little do we know that our good sense to bundle up is one step in an elaborate system to protect our body and organs from deep freeze. Our nervous system is the front line of defense against the cold. It causes us to react to our environment by informing the brain of temperature variations. When we head outside in 30 below zero weather, nerves in the skin, internal organs, brain and even tongue report temperature changes immediately to the brain.
