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 more pronounced in aquatic mammals and is thought to have originated as a way to conserve oxygen and enhance the ability to stay underwater for longer periods. Key components of the diving reflex include: Bradycardia: The heart rate decreases significantly when the face is exposed to cold water. This helps to conserve ...
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 term Mammalian diving reflex is not an accurate description, and therefore, the article should be renamed to the more general term, Diving response, with Mammalian diving reflex as a redirect. • • • Peter (Southwood) (talk): 14:02, 20 January 2017 (UTC) It appears that Diving reflex is also used in the literature.
The Beck Anxiety Inventory (BAI) is a formative assessment and rating scale of anxiety. This self-report inventory , or 21-item questionnaire uses a scale (social sciences) ; the BAI is an ordinal scale ; more specifically, a Likert scale that measures the scale quality of magnitude of anxiety.
Reflex syncope can occur in otherwise healthy individuals, and has many possible causes, often trivial ones such as prolonged standing with the legs locked. [ citation needed ] The main danger of vasovagal syncope (or dizzy spells from vertigo) is the risk of injury by falling while unconscious.

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.
