When the nervous system goes through something overwhelming, the vagus nerve can become dysregulated. It becomes less responsive and less able to deliver the "all clear" your body needs to calm down. Without that signal, the stress response does not fully turn off. The amygdala keeps sending threat signals, so the body stays on alert. Sleep is disrupted, the gut is affected, concentration breaks down, and the heart rate stays slightly elevated even when you are safe.
This is why trauma often feels like it lives in your body, not just your mind. Physiologically, it really does. The brain is not malfunctioning; it is doing exactly what it learned to do. The problem is that the brake is not working as it should.
Over time, being on high alert starts to feel normal. Calm can feel unfamiliar. Some people say it feels like they are waiting for something bad to happen, even when nothing is wrong, because their nervous system never fully got the message that the threat was over.
Accelerated Resolution Therapy uses bilateral eye movements during memory processing — smooth, guided, rhythmic movements that research suggests may activate the parasympathetic nervous system. As arousal lowers during a session, the vagus nerve can begin to do its job. The brake engages. The body receives the signal it has been waiting for.
When arousal is reduced, the prefrontal cortex can work again. The memory causing distress becomes accessible in a calmer state. The images connected to it can change, taking on a completely different emotional tone than before.
This effect can go beyond the sessions. Over the course of ART treatment, their body's resting baseline starts to change, and calm begins to feel less unfamiliar.
The vagus nerve learned to stay tense. With the right support, it can learn to relax again.
