For deep and natural breathing, the blocakge around the chest caused by stress has to be opened. Breathe naturally, focuusing on exhalation. Relaxing your chest and upper body will help you. To open the blockages, exhale with the mouth open slightly at the beginning stage, making a "ha-ah" sound through the throat to deeply release stagnant energy from the inside of the chest. After a certain time of exhaling this way, you may breathe with the mouth closed.
