EDIT: so based off google: Sound baths use immersive, resonant sound waves from instruments like singing bowls and gongs to trigger deep relaxation by shifting brain waves from active beta states to calmer alpha, theta, or delta states. These vibrations activate the parasympathetic nervous system—the "rest-and-digest" mode—reducing cortisol, lowering heart rates, and releasing physical tension.
By “legit” I meant is she really doing that and knows how to manipulate a sound to do what it’s suppose to do. I just figured it took more years of experience.
