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.
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).
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 ...
The diving reflex is triggered specifically by chilling the face and breath-hold. [ 6 ] [ 19 ] The most noticeable effects are on the cardiovascular system, which displays peripheral vasoconstriction, slowed pulse rate, redirection of blood to the vital organs to conserve oxygen, release of red blood cells stored in the spleen , and, in humans ...

The human body has several oxygen-conserving adaptations that manifest under diving conditions as part of the mammalian diving reflex. The adaptations include: Reflex bradycardia: Significant drop in heart rate. Blood-shift: Blood flow and volume is redistributed towards vital organs by means of a reflex vasoconstriction. Blood vessels distend ...
