Deep breathing is the act of breathing deep into one’s lungs by flexing one’s diaphragm rather than breathing shallowly by flexing one’s rib cage. This deep breathing is marked by expansion of the abdomen rather than the chest when breathing. It is generally considered a healthier and fuller way to ingest oxygen.
To breathe diaphragmatically, or with the diaphragm, one must draw air into the lungs in a way which will expand the stomach and not the chest. It is best to perform these breaths as long, slow intakes of air – allowing the body to absorb all of the inhaled oxygen while simultaneously relaxing the breather.
A common diaphragmatic breathing exercise is as follows:
- Sit or lie comfortably, with loose garments.
- Put one hand on your chest and one on your stomach.
- Slowly inhale through your nose or through pursed lips (to slow down the intake of breath).
- As you inhale, feel your stomach expand with your hand.
- Slowly exhale through pursed lips to regulate the release of air.
- Rest and repeat.
