The vagus nerve starts in the brainstem and extends through the face, throat, heart, diaphragm, and all organs. When a person is under threat, the vagus nerve controls our fight, flight, or freeze responses. Each individual perceives threat differently. A threat stimulus for one individual might be a safe stimulus for another. Research has found that individuals undergoing repeated or chronic trauma often have a dissociation or shutdown of the vagus nerve. If this sounds like you, then you probably need some help. Feel free to reach out, find a somatic experiencing therapist at traumahealing.org, or find a method of healing your trauma that works for you.
