In the natural state of the body, lips perform, in conjunction with the nose, a crucial role as the leading path in breathing. Breathing through the mouth is cohesively connected to the diaphragmatic breathing technique, which drives the body to move in any positions by inflating the back muscles to pull the abdomen upward during inhalation. By contrast, breathing through the nose links to the abdominal breathing technique, which stabilizes the body by inflating the abdomen downward to relax all body parts but the organs and muscles associated with the respiratory system. However, human movement is a series of complexity, and hence breathing is continued in a flexible way, not entirely dedicated one of those techniques. The tendency to unconsciously tighten lips, combined with a misunderstanding of the breathing mechanism, impairs the balance of the body. The tensed facial muscles set the nose as the only path of respiration which consists of one inhalation and one exhalation. Technically, this setting likely inclines to abdominal breathing, which is much slower than diaphragmatic breathing to obtain enough oxygen to generate the same amount of energy and thus does not fit active movements, which requires continual weight shifting from one place to another place like walking, running, jumping, and rolling. As human movement is complicated, the rigid facial muscles necessarily impede energy supply; therefore, shallow and frequent breathing is followed to compensate the lack of power. To avoid moving with the pernicious thoracic breathing flow, one should take a deep breath until oxygen naturally inflates the stomach when breathing through the nose; however, the speed of the half abdominal breathing cannot be fast enough to retain the momentum of continuous movements without the help of the mouth and lips. Furthermore, taking a deep breath through the nose naturally links to abdominal breathing, which alleviates the intensity of movements. In fact, breathing through the nose without the help of the mouth and lips can lead diaphragmatic breathing to support dynamic actions in velocity only when one is capable of switching breathing techniques according to one’s need and intention.
