The diving reflex is a set of physiological responses that occur in response to cold water immersion, particularly when the face or body is exposed to cold water. It is an evolutionary adaptation that helps mammals , including humans, manage the challenges of being submerged in cold water.
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 a response to immersion that overrides the basic homeostatic reflexes, and which is found in all air-breathing vertebrates. [6] [7] It optimizes respiration by preferentially distributing oxygen stores to the heart and brain which allows staying underwater for extended periods of time.
During the diving reflex, the infant's heart rate decreases by an average of 20%. [1] The glottis is spontaneously sealed off and the water entering the upper respiratory tract is diverted down the esophagus into the stomach. [6] The diving response has been shown to have an oxygen-conserving effect

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.
