WebbThe mammalian diving reflex consists of a series of adaptive reflexes which occur after submersion in cold water. The physiologic purpose of the diving reflex is not well understood, but is believed to be oxygen conservation, a quality evident in diving mammals, in which the response is most pronounced. http://www.ijsrp.org/research-paper-0315/ijsrp-p3918.pdf

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. It optimizes respiration by preferentially distributing oxygen stores to the heart and brain, enabling submersion for an extended time.
