Oxygen
It is a fact that physical symptoms can be healed by using breathing practices. There is a simple but encompassing reason that may explain this. The human body is designed to discharge 70 percent of its toxins through breathing. Only a small percentage of toxins are discharged through sweat, defecation, and urination. If your breathing isnot opeating at peak efficiency, due to being constantly triggered into the stress response, you are not ridding yourself of toxins properly. This means other systems of your body, such as your kidneys must work overtime. This overwork can set the stage for physical symptoms.
Shifting to abdominal breathing will nourish the body with oxygen so that you can cope with stress.
It is essential to integrate breathing practices into your daily routines.
I've just started doing abdominal breathing. It really helps. I count to 5 on the in breath,pause and count out 10 on the out breath. I do feel some pain in the shoulder and chest muscles from the toxins being liberated.
Yes, the tension that breathing releases is a great side-effect!
