Relaxing the diaphragm through subcostal self-massage combined with abdominal breathing helps release accumulated physical and emotional tension.

The diaphragm is a major inspiratory muscle whose mobility is effectively influenced by the autonomic nervous system. Cardiac coherence and slow abdominal breathing are supported by systematic reviews (e.g., Front. Psychol., 2017) for their ability to activate the parasympathetic system and reduce perceived stress. Regarding subcostal self-massage, this is a technique derived from manual therapy. While no robust clinical study proves that a massage can 'break' structural diaphragmatic tension, the sensory approach may decrease pain perception through local desensitization and voluntary relaxation. It is important to note that the diaphragm is protected by the rib cage and internal organs; therefore, direct mechanical action is modest, although the effect on surrounding soft tissues is real. The emotional aspect is consistent with the literature on the mind-body connection, where diaphragmatic breathing helps regulate anxiety. The approach is safe as long as the intensity remains moderate and respects the user's sensations.
