To give an example of this connection from a standpoint of science, it is well documented that simply emerging your face in the water triggers something called a "mammalian diving reflex". What this reflex does is basically automatically slow down your heart rate as soon as your face is submerged, as the body prepares to conserve oxygen for the expected dive. Very useful! Now, it is no surprise that aquatic mammals like seals and dolphins have this, but it very curious that humans have it too!
