Frostbite | Seasonal Science | UNC-TV

As the temperature drops, your fingers, toes, nose, ears, and cheeks get cold and numb.
Why? Because your body kicks into survival mode and reroutes blood from your extremities to your more important parts to fend off of hypothermia.
But without blood to warm them, your fingers, toes, nose, ears, and cheeks are, quite literally, left out in the cold.
