What is thermal protection in diving?

Thermal protection in diving refers specifically to measures and equipment designed to maintain the diver's body temperature in cold water environments, effectively preventing hypothermia. When divers are exposed to cold water, their body can lose heat rapidly, leading to a dangerous drop in core temperature. Thermal protection takes various forms, such as dry suits, wet suits, and other insulating garments that provide a barrier against the cold and help retain body heat.

Choosing thermal protection is crucial for divers in colder waters to ensure safety and comfort during their dives. It is designed to keep the diver warm by trapping a thin layer of water near the body (in the case of wet suits) or by preventing water from entering altogether (dry suits). This helps to maintain body temperature and allows for longer, more enjoyable dives in chilly conditions.
