The vagus nerve has the important job of ending your body’s fight-or-flight response once a stress has passed. That’s why vagus nerve stimulation is so effective for mood, and has been approved as a novel treatment for depression. Vagus nerve stimulation can also relieve migraines and rapidly quench inflammation.
I’m wondering, whether this could be an angle for novel therapies for PTSD and C-PTSD. It sounds to me as if it could.
