The diaphragm, a dome like muscle that forms the floor of the rib cage, is the most efficient muscle for breathing and relaxation. The correct use of diaphragmatic breathing can help to quiet brain activity resulting in the relaxation of all the muscles and organs of the body. This is accomplished by slow rhythmic breathing concentrated in the diaphragm rather than the chest.
Learning Diaphragmatic Breathing
Place one hand on your chest and one hand on your abdomen.
Exhale completely, breathing out through your mouth. Allowing your abdomen and chest to fall.
Inhale deeply. Breathe in through your nose and mouth while contracting the diaphragm. It will move downward causing your abdomen to rise. Keep your shoulders and chest relaxed during this exercise.
Remember to breathe slowly. Do not force your breathing.
