Breathing training to normalize breathing patterns may serve as a beneficial adjunctive therapy for managing conditions like hypertension, angina, and COPD.

May support adjunctive breathing retraining in select hypertension or COPD cases; hypothesis-generating and requires RCTs before practice change.
Breathing training is widely used as an aid in reducing anxiety states, but several other applications also show promise. This article reviews evidence that normalizing breathing patterns may offer help in some cases of essential hypertension, angina, functional chest disorder, chronic obstructive pulmonary disease (COPD), and cardiac rehabilitation. Hyperventilation and hypoventilation, inhibited breathing, and breath suspension are all deviations from an optimal breathing pattern in which breathing volume is closely matched to metabolic needs. Such disordered breathing has varying effects on acid/base balance, arterial diameter, and sodium retention by the kidneys. Therefore, a chronic breathing imbalance can contribute to pathophysiology, which may be remediable to an extent by altering habitual breathing patterns.
