What type of suit is generally recommended for preventing hypothermia during wreck dives?

The type of suit generally recommended for preventing hypothermia during wreck dives is a diving drysuit. A drysuit completely seals the body from external water, providing insulation that prevents heat loss and keeps divers warm even in cold water conditions.

In contrast, a diving wetsuit is also designed to provide thermal protection but works on a different principle. It allows a small amount of water to enter the suit, which is then warmed by the body heat of the diver. This can lead to a chilling effect if the water temperature is significantly low, especially during extended dives or when diving at greater depths.

An exposure suit is a more general term that could refer to both wetsuits and drysuits, but it does not specify which is most effective for preventing hypothermia specifically. Swimwear offers minimal thermal protection and is not suitable for wreck diving, especially in colder waters, as it does not provide insulation or protect against hypothermia.

Therefore, while an exposure suit may provide some level of protection, a drysuit is more effective for preventing hypothermia during the specific conditions associated with wreck diving.
