Normal breathing is relatively shallow and does not use the full capacity of the lungs. Diaphragmatic breathing is a deep breathing exercise that fully engages the diaphragm and increases the efficiency of the lungs. Diaphragmatic breathing, or “belly breathing,” involves fully engaging the stomach, abdominal muscles, and diaphragm when breathing. This means actively pulling the diaphragm down with each inward breath. In this way, diaphragmatic breathing helps the lungs fill more efficiently. During diaphragmatic breathing, a person consciously engages their diaphragm in order to take deeper breaths. A person will notice their stomach rising and falling. They will also feel an expanding or stretching sensation in the stomach, rather than solely in their chest and shoulders.
