Holotropic Breathwork is a therapeutic practice developed in the 1970s by psychiatrists Stanislav and Christina Grof. A Holotropic Breathwork session is usually led by a certified facilitator and involves the client breathing rapidly and deeply for a long period of time (usually one to three hours) while listening to music. The practice aims to help people heal from past traumas and explore their consciousness without the use of psychedelics. Many report emerging from the experience with a feeling of wholeness.
