Diving reflex in a human baby The diving reflex , also known as the diving response and mammalian diving reflex , is a set of physiological responses to immersion that overrides the basic homeostatic reflexes , and is found in all air-breathing vertebrates studied to date.
The diving reflex is triggered specifically by chilling the face and breath-hold. [ 6 ] [ 19 ] The most noticeable effects are on the cardiovascular system, which displays peripheral vasoconstriction, slowed pulse rate, redirection of blood to the vital organs to conserve oxygen, release of red blood cells stored in the spleen , and, in humans ...
Edmund Goodwyn, M.D. (1756–1829) was an English physician whose medical school graduation thesis contains several important contributions, [1] including the discovery of the diving reflex. [2] He advanced early important arguments in favor of artificial ventilation for the treatment of asphyxia over alternative resuscitation measures of the ...

The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes , sea turtles , the marine iguana , saltwater crocodiles , penguins , pinnipeds , cetaceans , sea otters , manatees and dugongs .
Training in the characteristics and use of breathing apparatus as relevant to the certification. Diver training is the set of processes through which a person learns the necessary and desirable skills to safely dive underwater within the scope of the diver training standard relevant to the specific training programme.
