Which physiological response is commonly associated with mild hypothermia?

Shivering is a physiological response that is commonly associated with mild hypothermia. When the body begins to cool down due to exposure to cold environments, it initiates shivering as a mechanism to generate heat. The rapid, involuntary muscle contractions during shivering help to increase the body temperature by producing metabolic heat. This response is an important part of the body's homeostatic efforts to maintain core temperature and is typically one of the first signs of mild hypothermia.

As for the other responses, loss of consciousness typically occurs in more severe cases of hypothermia. Hypotension, or low blood pressure, can occur in severe hypothermia as the body struggles to maintain adequate perfusion. Hyperthermia, which refers to an elevated body temperature, is not related to hypothermia and would not be expected in this context. Thus, shivering is the correct physiological response associated with mild hypothermia, indicating the body’s efforts to counteract decreased temperature.
