What is the main purpose of exposure suits during dives?

• A. To provide buoyancy
• B. To preserve heat
• C. To enhance visibility
• D. To protect from impact

Answer: (B)

The primary function of exposure suits during dives is to preserve heat. When underwater, especially at depth, the temperature can significantly drop, leading to rapid heat loss from the body. Exposure suits, such as wetsuits or drysuits, are designed to create a layer of insulation that helps maintain body temperature by trapping a thin layer of water between the suit and the diver's skin, which warms up and helps minimize heat loss. This insulation is crucial for preventing hypothermia and ensuring that divers can safely enjoy longer dives in cooler waters. While exposure suits may also provide some buoyancy, enhance visibility through bright colors, and offer protection from impacts or scrapes, their main and most critical purpose remains thermal insulation. This is especially important in various diving conditions where maintaining body warmth is essential for safety and comfort.
