Use Your Built-in Mammalian Diving Reflex To Quickly Relax

Did you know you have a superpower? The human body is has a built-in mechanism that, when triggered, will help you quickly relax, not matter how much you were freaking out just moments before. It's called the Mammalian Diving Reflex and all you need to use it is a bucket of cold water.

It's a simple three-step process:

1) First, fill a bucket with ice cold water.

2) Hold your breath and dunk your face in it, making sure the area under your eyes and above your cheekbones is submerged.

3) Wait for 30 seconds before resurfacing.

This process kicks in the Mammalian Diving Reflex, which automatically slows your heart rate down by 10 to 30 per cent, and narrows the blood vessels so the oxygen rushes more to the brain and the heart.

About 30 seconds after you emerge, you'll find the effects really kicking in, forcing the parasympathetic nervous system (PNS) to calm you down.
