Which signs and symptoms might indicate a diver is suffering from hypothermia?

Hypothermia occurs when the body loses heat faster than it can produce it, leading to a dangerous drop in core body temperature. All the signs and symptoms mentioned are indeed indicative of hypothermia.

Uncontrollable shivering is often one of the first signs, as the body attempts to generate heat through muscle activity. As hypothermia progresses, the body's ability to maintain normal physiological functions declines. This includes slowed mental processes; a diver may experience confusion, poor decision-making, or difficulty concentrating. Additionally, the diver may appear drowsy, uncoordinated, and forgetful, as the cold affects both motor functions and cognitive abilities.

Recognizing these symptoms is crucial for divers, as hypothermia can become life-threatening if not addressed promptly. Thus, the correct answer encompasses all of these signs as essential indicators of hypothermia.
