When you get too cold and start shivering?

When you get too cold, your body begins to lose heat faster than it can produce it, triggering a response to maintain your core temperature. Shivering is an involuntary muscle contraction that generates heat through increased metabolic activity, helping to warm the body. This reflex action is a crucial survival mechanism that prompts you to seek warmth or add layers to prevent further heat loss. If exposure continues, however, it can lead to hypothermia, a serious condition requiring immediate attention.
