Which breathing practice utilizes the diaphragm and intercostal muscles effectively?

The practice of deep breathing is recognized for its effective engagement of the diaphragm and intercostal muscles. When deep breathing occurs, the diaphragm, which is a dome-shaped muscle located at the base of the thoracic cavity, contracts and moves downward. This action allows the lungs to expand fully, creating a vacuum that pulls air in. Simultaneously, the intercostal muscles, which are located between the ribs, assist by lifting the rib cage and creating additional space in the chest cavity, further facilitating lung expansion.

This coordinated effort promotes optimal oxygenation of the blood, enhances lung capacity, and can induce a state of relaxation and calm. Deep breathing is particularly beneficial as it encourages a lower, more effective form of breathing that is associated with a state of rest and recovery. This contrasts with other forms of breathing, such as shallow breathing, which tends to engage only the upper portions of the lungs, or fast breathing, which can lead to hyperventilation and reduced carbon dioxide levels in the blood, resulting in a range of physiological effects. Breath retention, while it can develop control over breath, does not primarily focus on the engagement of these muscles in the same way that deep breathing does.
