Question: 1 / 400

What condition can result from continued loss of body heat in cold water?

Nausea

Dizziness

Muscle cramps

The correct condition that can result from continued loss of body heat in cold water is muscle cramps. When a diver is exposed to cold water for an extended period, the body loses heat faster than it can produce it, leading to hypothermia. As body temperature drops, muscles can become less efficient and may start to cramp as a response to the cold and fatigue.

In cold water, the muscles require more energy to maintain function, and if the energy supply diminishes due to the cold-induced stress, muscle cramps can occur as a protective mechanism. The physiological stress also affects blood circulation, which can contribute to the likelihood of cramping.

Nausea, dizziness, and sore joints may occur due to various factors related to diving or other conditions, but they are not directly related to prolonged exposure to cold water and the resultant loss of body heat in the same way that muscle cramps are.
