Why Do We Shiver?

Ask Us Questions

When we sweat, our body secretes a liquid on the skin, which helps lower the body temperature. When we shiver, the opposite process takes place. When the outside temperature drops, the body starts to feel cold as the temperature inside and outside the body are radically different. To help the body produce heat and to prevent the body temperature from going below normal, the body automatically triggers a shivering reaction and the muscles begin to shake. Shivering and sweating are two body mechanisms that help keep the body temperature normal.
