How does temperature affect a diver's body?

Temperature plays a significant role in how a diver's body responds underwater. When diving in cold water, the body loses heat more rapidly than it can generate it, which can lead to hypothermia—a potentially dangerous condition where the body's core temperature drops to dangerously low levels. Symptoms of hypothermia include shivering, reduced motor skills, confusion, and in severe cases, loss of consciousness. Proper thermal protection, such as wetsuits or drysuits, is essential to maintain body heat in cold environments.

On the other hand, warm water can also impact a diver’s body, particularly concerning circulation. In warmer temperatures, blood vessels dilate, which can increase blood flow to the skin. While this might seem beneficial, it can lead to an increased risk of dehydration and, in extreme cases, heat stress. It's crucial for divers to stay hydrated and monitor their physical condition when diving in warmer waters.

The correct answer highlights the importance of being aware of how temperature changes can influence a diver's overall health and safety, emphasizing the need for appropriate equipment and precautions in different water conditions.
