Static apnea (STA) is a discipline in which a person holds their breath underwater for as long as possible, and need not swim any distance. [1] 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 ...
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]
They spend most of their time underwater, so must be able to hold their breath for long periods to avoid frequent surfacing. Dive duration largely depends on the activity. A foraging sea turtle may typically spend 5–40 minutes under water [108] while a sleeping sea turtle can remain underwater for 4–7 hours.
The pulse rate in an untrained diver, the Daily Mail says, will decrease 10 to 30 percent when underwater. But professional divers can reduce theirs by more than 50 percent. This brings us to records.

Elite freediving coach Kirk Krack shares 3 drills that he uses to help people learn to optimize their lung functions for better performance.
Mild bradycardia is caused by subjects holding their breath without submerging the face in water. [10] [11] When breathing with the face submerged, the diving response increases proportionally to decreasing water temperature. [8] However, the greatest bradycardia effect is induced when the subject is holding their breath with their face wetted ...
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.
