As a respiratory physiologist, I can tell you that the two main types of breathing are costal breathing (also known as chest breathing) and diaphragmatic breathing (also known as abdominal breathing). Costal breathing involves the expansion of the ribcage, primarily using the intercostal muscles to move the ribs upward and outward. This type of breathing is more superficial and is common during light physical activity or when you're feeling anxious. Diaphragmatic breathing, on the other hand, is a deeper form of breathing that involves the contraction of the diaphragm muscle. As the diaphragm contracts, it moves downward, increasing the volume of the chest cavity and allowing the lungs to expand more fully. This type of breathing is more efficient and is often used during rest or sleep, as well as during deep relaxation or meditation. A third variety, clavicular breathing, is used when the body requires an even greater volume of air, such as during heavy exercise or when the diaphragm is compromised. This type of breathing is characterized by an upward and outward movement of the upper chest and clavicles. read more >>

There are two main types of breathing : costal (meaning ��of the ribs��) or chest breathing, and diaphragmatic or abdominal breathing. Only when we take a maximum breath is a third variety used, known as clavicular breathing. This type of breathing is characterised by an outward, upward movement of the chest wall.read more >>
