Diaphragm Function and Healthy Chemical Releases in the Body

When practicing diaphragm type breathing is a chemical released in the body?   Thanks very much,  Dawn E

From Mike:

Interesting question. Endorphins relate to breathing quite a bit. So do respiratory neuropeptides.  Adrenaline as well if the breath is high chest or stressful. Whether they are directly related to the diaphragm function I do not know. I suspect the answer is yes. The breathing process causes them to proliferate but only if the breathing is done in a certain way. Optimal Breathing techniques and exercises create extra amounts of great feeling states so that makes the diaphragm a leading contributor .
