Humans are supposed to belly breathe

The diaphragm, a dome-shaped muscle at the base of the lungs, plays an important role in breathing — though you may not be aware of it. When you inhale, your diaphragm contracts (tightens) and moves downward. This creates more space in your chest cavity, allowing the lungs to expand. When you exhale, the opposite happens — your diaphragm relaxes and moves upward in the chest cavity.

All of us are born with the knowledge of how to fully engage the diaphragm to take deep, refreshing breaths. As we get older, however, we get out of the habit. Everything from the stresses of everyday life to the practice of "sucking in" the stomach for a trimmer waistline encourages us to gradually shift to shallower, less satisfying "chest breathing."

Relearning how to breathe from the diaphragm is beneficial for everyone. Diaphragmatic breathing (also called "abdominal breathing" or "belly breathing") encourages full oxygen exchange — that is, the beneficial trade of incoming oxygen for outgoing carbon dioxide. Not surprisingly, this type of breathing slows the heartbeat and can lower or stabilize blood pressure.

Proper and routine belly breathing WILL have a profound impact on your daily life.

I can say this because so few people actually use belly breathing and those who do, might not be doing it right. Once you implement this one practice, you will feel your body literally change. For those of you who love the science of things, read the following article on the Vagus nerve.
