The Physiology of Belly Breathing

Physiology of Belly Breathing

How Diaphragmatic Breathing Activates Our Relaxation System

Why “belly” breathing calms us down and keeps our brain from being emotionally reactive:

Research has shown that just 20 min­utes of diaphrag­mat­ic breath­ing is all that’s need­ed to acti­vate and oxy­genate the mind­ful and think­ing part of the brain (the pre­frontal cor­tex).

  1. A bel­ly breath caus­es the lungs to press on the diaphrag­mat­ic wall.
  1. The diaphrag­mat­ic wall push­es down on the abdom­i­nal cav­i­ty (like a bal­loon being squeezed).
  1. The squeezed abdomen spreads out­ward in the front of the abdomen and the back where it press­es on the spine.
  1. This caus­es the abdom­i­nal cav­i­ty to put pres­sure on the longest cra­nial nerve, the vagus nerve, which runs all the way downs from the brain stem and the spine.
  1. When pressed on, the vagus nerve qui­ets down and turns on the body’s relax­ation sys­tem and reg­u­lates the parasym­pa­thet­ic ner­vous sys­tem (in con­trast to the instant grat­i­fi­ca­tion nerve).

What happens when the vagus nerve gets quieted down:

  1. Blood pres­sure, pulse rate, and res­pi­ra­tion become low­er.
  1. Lactate (which increas­es feel­ings of anx­i­ety) gets cleansed from the blood.
  1. Alpha brain waves (calm and alert) are increased.
  1. The neu­ro­trans­mit­ter sero­tonin is released, gets into the blood­stream and up to the brain in about 20 – 30 sec­onds. About 95 per­cent of this feel-good neu­ro­trans­mit­ter is stored in the stom­ach lin­ing and intestines (our gut).

No wonder breathing blocks reactivity and unhealthy emotions, helps you feel better, and think more clearly!

Everyday Mindfulness and Brain Integration

I think it’s impor­tant that my clients under­stand the phys­i­ol­o­gy of rela­tion­ships and the sig­nif­i­cance of an inte­grat­ed brain in build­ing healthy rela­tion­ships. Dr. Dan Siegel is at the fore­front of the lat­est neu­ro­bi­ol­o­gy research on how brain inte­gra­tion shapes rela­tion­ships and rela­tion­ships shape the brain. One of the ways you can cul­ti­vate a more inte­grat­ed brain is through mind­ful­ness tech­niques.

Here are some tools to help foster this symbiotic process:
