Detoxification
The human body is designed to rid itself of 70% of its toxins through breathing. If you are not breathing properly you are not detoxifying properly, which leads to stress being placed on other organs such as the kidneys and liver which have to overwork in order to compensate. This can set the stage for a number of illnesses.
"Oxygen gets rid of toxicity. Bacteria, viruses and parasites are destroyed in the presence of oxygen and conversely can thrive where Oxygen is not."

Dr. Alec Borsenko
Deep diaphragmatic breathing increases the rate of toxic elimination by as much as 15 times the normal rate.
