👉 Hypothermia, also known as cold exhaustion or frostbite, is a condition characterized by severe and prolonged low body temperature. It occurs when the central nervous system remains at an extremely reduced level of energy, resulting in a rapid decrease in the metabolic rate, which leads to overheating and consequent thermal injury. This can be caused by various factors such as long exposure to cold temperatures, excessive physical activity, or certain medical conditions like frostbite.
