What is not a sign of hypothermia?

In the context of hypothermia, understanding the physiological and behavioral signs is crucial for effective assessment and intervention. Shivering is a common and early response to cold exposure as the body attempts to generate heat. Confusion can occur as hypothermia progresses because the body’s functions and mental status are affected by decreased body temperature, leading to impaired cognitive function. Lethargy is also a sign that indicates a significant reduction in energy and alertness due to the cold's impact on the body and brain.

In contrast, an increased heart rate is not typically a sign of hypothermia. In fact, as the body cools, the heart rate often decreases as the body enters a state of slowed metabolism and cardiovascular function. This decrease can lead to bradycardia, which is a hallmark of severe hypothermia. Therefore, recognizing this distinction helps in critically distinguishing the symptoms of hypothermia, facilitating timely and appropriate responses in wilderness medicine situations.
