What is hypothermia and why is it considered dangerous?

Hypothermia is defined as a medical emergency that occurs when the body loses heat faster than it can produce it, leading to a core temperature that drops below 95°F (35°C). This condition is dangerous because the body is unable to function normally at such low temperatures, impairing the cardiovascular and nervous systems. As the temperature decreases, physiological processes become increasingly ineffective, resulting in symptoms such as slurred speech, slow and shallow breathing, confusion, drowsiness, and loss of coordination. If left untreated, hypothermia can lead to severe complications, including organ failure and death.

The other options present incorrect definitions or contexts. A temperature above 100°F relates to hyperthermia or conditions like heat stroke, while dehydration refers to insufficient fluid intake in hot weather, not a drop in body temperature. A mild reaction to cold environments does not convey the severity and danger associated with hypothermia, which is a critical health risk requiring immediate attention.
