A simple scientific fact applied

Human beings have been walking upright for centuries. Therefore, the body function is directly connected to the gravitational pull of the earth. It also affects the physiology of breathing. At the top of the lungs, up near the collar bone, the rate of blood flow is less than a tenth of a litre per minute. That means only about half a teacup of blood moves through the upper part of the lungs. On the other hand, the blood flow at the bottom of the lungs (down towards the bottom of the rib cage), is well over a litre a minute. Most of the blood circulation is in the bottom third of the lungs.

If the belly muscles are tense, preventing you from breathing deeply into your abdomen, you are not getting the oxygen down to where all the blood is. At rest, when you establish correct breathing, your breath rate will usually drop from 14 to 15 breaths per minute to 8 to 12 breaths per minute. This is because you get more deeply oxygenated blood and so the lungs don’t have to work as hard. As a result, your heart rate will also slow down because it does not have to pump as much blood to get a full supply of oxygen to the body. This is why if you corrected this one problem and did nothing else, you would make major improvements in your emotional, mental and physical functioning.
