Diving Response: The Mammalian Dive Reflection

Improved Essays
Humans and other mammals have a Diving Response, which can be also known as ‘The Mammalian Dive Response/Reflex.

This is a clever psychological mechanism because it enables our bodies to manage and to tolerate a lower level of oxygen in an environment that we do not normally face every day.

There are three main changes that occur in our body when our Dive reflex triggers; Bradycardia, Peripheral vasoconstriction and blood shift.
Bradycardia is an abnormal action that is slower than the average-normal heart rate. The normal resting heart rate for children 10 years and older (including adults and seniors) is 60 to 100 beats per
