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 ...
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).
It will stimulate a vagal response via the mammalian dive reflex and lower your heart rate. (and obviously go to the doctor to get checked out after). Image credits: HoldMyTurtle_13
Hanger reflex - reflex of unclear purpose that causes the head to rotate to the right when the top sides of the head are under pressure, named because it can be easily activated with a coat hanger; Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung
Human physiology of underwater diving is the physiological influences of the underwater environment on the human diver, and adaptations to operating underwater, both during breath-hold dives and while breathing at ambient pressure from a suitable breathing gas supply.
Edmund Goodwyn, M.D. (1756–1829) was an English physician whose medical school graduation thesis contains several important contributions, [1] including the discovery of the diving reflex. [2] He advanced early important arguments in favor of artificial ventilation for the treatment of asphyxia over alternative resuscitation measures of the ...
The visual cliff is an apparatus created by psychologists Eleanor J. Gibson and Richard D. Walk at Cornell University to investigate depth perception in human and other animal species. It consists of a sturdy surface that is flat but has the appearance of a several-foot drop part-way across.
