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.
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 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.
The instinctive drowning response is an instinctive reaction that occurs in humans, particularly in non-swimmers, when close to drowning.It is focused on attempting to keep the mouth above water to the exclusion of useful effort to attract help or self rescue, and is often not recognized by onlookers.
As with other recreational activities, freediving and scuba-diving can provide immersive experiences that can help to reduce stress. [3] A study by Marlinge et al. (2019) has shown that scuba diving helped to promote relaxation which can lower levels of multiple stress markers like cortisol, copeptin and ischemia-modified albumin (IMA) levels. [4]
