Hypothermia occurs when the body loses heat faster than it can produce it, causing the body temperature to drop below the normal level. Shivering is a common symptom of hypothermia as it is the body's natural response to try and generate heat. Option A, overheating, is incorrect because hypothermia is the opposite of overheating and occurs in cold temperatures. Option B, intense thirst, may cause dehydration but is not a common symptom of hypothermia. Option D, rapid heartbeat, can be a symptom of more severe cases of hypothermia, but it is not a common symptom and may indicate a more serious condition. Therefore, the most appropriate answer is option C, shivering.
