Kate Winslet, who held her breath underwater for 7 minutes and 14 seconds while filming "Avatar: The Way of Water," said the feat involved both physical and mental conditioning.
Human physiology of underwater diving is the physiological influences of the underwater environment on the human diver, and adaptations to operating underwater, both during breath-hold dives and while breathing at ambient pressure from a suitable breathing gas supply.
Blood shift is a term used when blood flow to the extremities is redistributed to the head and torso during a breath-hold dive. Peripheral vasoconstriction occurs during submersion by resistance vessels limiting blood flow to muscles, skin, and viscera , regions which are " hypoxia -tolerant", thereby preserving oxygenated blood for the heart ...
The technique ranges from simple breath-hold diving to competitive apnea dives. Fins and a diving mask are often used in free diving to improve vision and provide more efficient propulsion. A short breathing tube called a snorkel allows the diver to breathe at the surface while the face is immersed.
Finswimming is an underwater sport consisting of four techniques involving swimming with the use of fins either on the water's surface using a snorkel using either monofins or bifins (i.e. one fin for each foot) or underwater with monofin either by holding one's breathe or underwater using open circuit scuba diving equipment.
