What are four types of breathing?

Four types of breathing include diaphragmatic breathing, which involves the diaphragm and promotes deep, efficient breaths; chest breathing, which primarily uses the upper chest and is often shallow; nasal breathing, which filters and warms air as it enters the lungs; and pursed-lip breathing, which helps control breath and increase oxygenation by prolonging exhalation. Each type has different benefits and is used in various contexts, such as relaxation, exercise, or respiratory therapy.
