Why does your body experience a sudden violent shiver when you step into cold air?
The moment I walk outside in winter without a jacket, my body starts shaking uncontrollably. What biological survival system triggers this muscle contraction?

Shivering is an involuntary somatic reflex triggered by the hypothalamus. It forces your skeletal muscles to contract and expand rapidly, generating vital core body heat through cellular friction.
