What Causes the ‘Shiver’ of Cold Air?

Cold air makes us shiver because our bodies are trying to stay warm. When we feel cold, our muscles start to shake quickly, it’s like a little dance inside our body that helps create heat. This shaking is called shivering, and it keeps us from getting too chilly.
