"A Sound Bath is a deeply immersive, full-body listening experience that intentionally uses sound to invite therapeutic and restorative effects to the mind and body."

quote by Sara Auster, from her book Sound Bath

Sound baths are so popular because with essentially no preparation for the client, sound entrainment can lead to deep relaxation of body and trance-like states of the mind, which in turn trigger the body's and mind's own natural functions to repair and restore.
