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 first stage of cold water immersion syndrome, the cold shock response, includes a group of reflexes lasting under 5 min in laboratory volunteers and initiated by thermoreceptors sensing rapid skin cooling. Water has a thermal conductivity 25 times and a volume-specific heat capacity over 3000 times that of air; subsequently, surface cooling ...
Drowning is a leading cause of unintentional injury and death worldwide, and the highest rates are among children. Overall, drowning is the most common fatal injury among children aged 1–4 years in the USA, [8] and is the second highest cause of death altogether in that age range, after congenital defects.
In medicine, the caloric reflex test (sometimes termed ' vestibular caloric stimulation ') is a test of the vestibulo-ocular reflex that involves irrigating cold or warm water or air into the external auditory canal. This method was developed by Robert Bárány, who won a Nobel prize in 1914 for this discovery.
Messy Goes to OKIDO is a 2015 animated series for children, adapted from characters in OKIDO, a children's arts and science magazine.Inquisitive monster Messy, voiced by Adam Buxton, has adventures with his best friends Zoe and Felix in the colourful world of OKIDO. [2]
Children who have near-drowning accidents in water near 0 °C (32 °F) can occasionally be revived, even over an hour after losing consciousness. [74] [75] The cold water lowers the metabolism, allowing the brain to withstand a much longer period of hypoxia.

"Beyond the effect of the reflex when submerged in water, the reflex is used consciously in splashing cold water on one's face." No I really don't think that splashing water on your face causes your heart rate to drop to 10/minute. Cold water splashing wakes you up because its cold water hitting your face, which is warmer than cold water.
