This study aims to investigate whether breathing techniques, namely Holotropic Breathwork, can aid in the development of self-awareness. To do this, they used both a quasi-experiment design and multiple case studies. The 20 participants participated in 4 Holotropic Breathwork sessions separated by 12-weeks over the course of the experimental portion. The findings demonstrated that novices experienced positive temperament changes, while experienced participants exhibited positive changes in character traits. However, all participants demonstrated enhanced self-awareness, as evidenced by reduced scores in persistence temperament, interpersonal problems, accommodation tendencies, neediness, and hostility.
