Which of the following is NOT a symptom of hypothermia?

Hypothermia occurs when the body loses heat faster than it can produce it, causing body temperature to drop to dangerously low levels. The symptoms associated with hypothermia are the body’s response to the cold, and they can vary as the condition worsens.

Muscle cramps, progressive weakness, and insensibility to pain are all common symptoms of hypothermia. Muscle cramps can occur due to the body’s muscles becoming stiff and unable to function properly in cold conditions. Progressive weakness is a sign that the body's systems are becoming overwhelmed by the cold, leading to a reduced ability to move. Insensibility to pain can also develop, as hypothermia can lower the body’s sensitivity to pain, making it harder for an individual to recognize injuries or the severity of their condition.

Headaches, however, are not typically associated with hypothermia. While they can occur for various reasons, they do not represent a direct symptom of hypothermia itself. Instead, they are more indicative of dehydration, stress, or other environmental factors that may be present but are not core signs of the cold-induced physiological responses seen in hypothermia. Thus, identifying headaches as a symptom of hypothermia is incorrect, making this the right answer to choose.
