This hasn’t always been the case:
“Until the seventeenth century most of the great physicians and anatomists were interested in the respiratory muscles and the mechanics of breathing. Since then, these muscles have been increasingly neglected, lying as they do in a no-man’s land between anatomy and physiology.”

“Most of us aren’t that sensitive. It’s much more common, especially in the modern world, to never experience full-blown, life-threatening stress, but to never fully relax either. We’ll spend our days half-asleep and nights half-awake, lolling in a gray zone of half-anxiety. When we do, the vagus nerve stays half-stimulated.
“During these times, the organs throughout the body won’t be “shut down,” but will instead be half supported in a state of suspended animation: blood flow will decrease and communication between the organs and the brain will become choppy, like a conversation through a staticky phone line. Our bodies can persist like this for a while; they can keep us alive, but they can’t keep us healthy.”

“You cannot influence or control the heart rate directly; it’s an autonomic function. So, once again, you use a “handle” to accomplish it — diaphragmatic deep breathing, which, once you master it, makes your breathing more profound and more regular. What do I mean by more profound and regular? Profound means still, as in silent; regular means rhythmic.
“When you extend the belly, pushing it outward on inhalation and then pulling the belly in to expel air, you are embarking on a regimen of abdominal and diaphragmatic calisthenics. Starting this activity for the first time — whether sitting, walking, reclining, or lying down — you may feel a burning sensation. That is the muscles of the abdomen telling you that you are beginning to breathe correctly. Using the belly muscles is like pump priming, that is, using the handle of a pump (the belly) to activate the pump mechanism (the diaphragm).”

“Breathing is an autonomic function we can consciously control. While we can’t simply decide when to slow or speed up our heart or digestion, or to move blood from one organ to another, we can choose how and when to breathe. Willing ourselves to breathe slowly will open up communication along the vagal network and relax us into a parasympathetic state.”

“The best way to keep tissues in the body healthy was to mimic the reactions that evolved in early aerobic life on Earth—specifically, to flood our bodies with a constant presence of that “strong electron acceptor”: oxygen. Breathing slow, less, and through the nose balances the levels of respiratory gases in the body and sends the maximum amount of oxygen to the maximum amount of tissues so that our cells have the maximum amount of electron reactivity.
“In every culture and in every medical tradition before ours, healing was accomplished by moving energy,” said Szent-Györgyi. The moving energy of electrons allows living things to stay alive and healthy for as long as possible. The names may have changed—prana, orenda, ch’i, ruah—but the principle has remained the same. Szent-Györgyi apparently took that advice. He died in 1986, at the age of 93.”
