What is the primary purpose of an exposure suit during dives?

• A. Increase buoyancy in water
• B. Protect skin from sunburn
• C. Preserve body heat during dives
• D. Provide insulation from cold water

Answer: (C)

Exposure suits exist to keep the diver warm by reducing heat loss to the surrounding water. Water pulls heat away from the body much faster than air, so without protection you’d get cold quickly. The suit—whether a wetsuit with neoprene or a dry suit with insulating undergarments—acts as an insulating barrier, helping you preserve body heat throughout the dive. That improved warmth supports comfort, dexterity, and safety by lowering the risk of hypothermia during longer or deeper exposures. While a suit can add some buoyancy and might offer surface sun protection, those are not the main reasons for wearing it. The primary goal is to prevent heat loss and keep the diver warm.
