Which of the following is a sign of hypothermia in swimmers?

The presence of shivering is a classic sign of hypothermia in swimmers. When a person is exposed to cold water for an extended period, the body loses heat more rapidly than it can produce it. As the body temperature drops, the individual may start to shiver as a physiological response to generate heat. Shivering is an attempt by the body to maintain its core temperature, and its intensity can vary depending on the severity of the hypothermia.

Other signs of hypothermia can include confusion, fatigue, and impaired motor function. In contrast, excessive laughter, improved coordination, and high energy are not consistent with hypothermia. In fact, as body temperature continues to decline, coordination and energy levels typically decrease, leading to increased risk and dangerous situations for swimmers. Recognizing shivering as a sign of hypothermia is crucial for early intervention and preventing further complications.
