What is a common sign of hypothermia?

Shivering is a common and early sign of hypothermia, which occurs when the body loses heat faster than it can produce it, leading to a decrease in core temperature. As the body attempts to generate heat to counteract the cooling effect, involuntary muscle contractions manifest as shivering. This response is a physiological mechanism aimed at raising body temperature.

While pain in limbs, high blood pressure, and severe headaches can indicate various medical issues, they are not typically associated with hypothermia. In fact, as hypothermia progresses, individuals may stop shivering and exhibit more severe symptoms, such as confusion and lethargy, as their body's ability to respond diminishes. Recognizing shivering as an initial indication of hypothermia is essential for timely intervention and treatment.
