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.
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 ...
Most human babies demonstrate an innate swimming or diving reflex from birth until the age of approximately six months, which are part of a wider range of primitive reflexes found in infants and babies, but not children, adolescents and adults. Other mammals also demonstrate this phenomenon (see mammalian diving reflex).
Of course, the human body has its own built-in defenses for such a shock called the mammalian diving reflex. “And that’s why you hear these kids that you know, have been submerged in an icy ...

Scuba diving can decrease depression, anxiety and PTSD in military veterans and people that are dealing with such mental illnesses. [7] Diving allows patients to achieve a feeling of liberty, due to the concentration needed for the duration of the dive. This leads to an increase in mindfulness and a decrease in depression and anxiety levels ...
