Hypothermia is reduced body temperature that happens when a body dissipates more heat than it absorbs and produces. [20] Clinical hypothermia occurs when the core temperature drops below 35 °C (95 °F). [21] Heat loss is a major limitation to swimming or diving in cold water. [8]
Tolerance can in addition be trained. The ancient technique of free-diving requires breath-holding, and world-class free-divers can hold their breath underwater up to depths of 214 metres (702 ft) and for more than four minutes. [4] Apneists, in this context, are people who can hold their breath for a long time.
Humans set breath-holding records in water because they "can hold their breath twice as long underwater they can on land." The world record is 19 minutes and 30 seconds. It depends--but you can ...

Static apnea is defined by the International Association for Development of Apnea (AIDA International) and is distinguished from the Guinness World Record for breath holding underwater, which allows the use of oxygen in preparation. It requires that the respiratory tract be immersed, with the body either in the water or at the surface, and may ...
Recreational breath-hold divers in basic equipment with floats and catch bags suitable for collecting lobster or shellfish. The ability to dive and swim underwater while holding one's breath is considered a useful emergency skill, an important part of water sport and Navy safety training, and an enjoyable leisure activity.
