Why is my therapist on my last nerve?

Vagus Nerves role in trauma processing

If you’ve ever said, “I know I’m safe, but my body doesn’t feel safe,” you are not alone. Many trauma survivors understand, intellectually, that the danger is over—yet their bodies continue to brace, scan, shut down, or react as if the past is still happening now. This is not a character flaw or a lack of willpower. It is your nervous system trying to protect you.

One important part of that nervous system story is the vagus nerve. The vagus nerve is often described as a communication highway between the brain and body, traveling from the brainstem through the face, throat, heart, lungs, and digestive system. It plays a central role in the parasympathetic nervous system—the part of the body involved in rest, digestion, repair, and social connection. When we spend the majority of our lives trying to survive harm, traumatic invalidation, or sensory overwhelm, our bodies can lose the felt sense of connection to the vagus nerve causing us to feel numb, disconnected, or in a constant state of anxiety, anger, or powerlessness.

Why the Vagus Nerve Matters in Trauma Healing

Trauma does not only live in thoughts or memories. It can also live in the body’s automatic survival responses. When your nervous system senses threat, it may move into fight, flight, freeze, collapse, people-pleasing, or emotional shutdown. These responses are not “overreactions.” They are adaptive strategies your system learned to help you survive what felt unsurvivable at the time.

Polyvagal Theory offers one helpful way to understand this. It describes how the autonomic nervous system shifts between states of connection, mobilization, and shutdown depending on whether the body detects safety or danger. In therapy, this can help us move away from asking, “What is wrong with me?” and toward a more compassionate question: “What is my nervous system trying to do for me?”

Vagal Strengthening from an EMDR Perspective: Helping the Body Know the Past Is Over 

EMDR therapy helps the brain and body reprocess memories that may feel stuck in the nervous system. A trigger in the present—a tone of voice, a facial expression, a smell, a conflict, or even a body sensation—can activate an old memory network. You may suddenly feel small, trapped, ashamed, panicked, numb, or on high alert, even when part of you knows the current situation is different.

Strengthening vagal regulation can support EMDR by helping you stay within your window of tolerance—the zone where you can feel enough safety and steadiness to process difficult material without becoming overwhelmed or disconnected. This does not mean forcing yourself to be calm. It means building the capacity to notice what is happening in your body and return, gently and repeatedly, to the present moment.

Vagal Strengthening from an The IFS Perspective: Listening to Protective Parts with Compassion

In Internal Family Systems, we understand that different parts of us may carry different roles. Some parts work hard to prevent pain. Some parts react quickly when danger feels near. Some parts hold old wounds, grief, fear, or shame. When the nervous system is activated, these protective parts may become louder, more urgent, or more extreme. 

Vagus nerve practices can be a way of saying to those parts: “I hear you. I’m not going to push you away. Let’s help the body feel a little more supported right now.” When the body experiences even a small increase in safety, it can become easier to access Self-energy—qualities such as calm, curiosity, compassion, clarity, courage, confidence, creativity, and connectedness.

What Does It Mean to “Strengthen” the Vagus Nerve?

Strengthening the vagus nerve does not mean doing one dramatic exercise and suddenly becoming regulated forever. It is more like building a relationship with your nervous system over time. Gentle, small, repeated experiences of safety can teach the body that it has options beyond survival mode.

In everyday language, stronger vagal tone can support your ability to recover after stress. You may still feel activated, but you may come back to baseline more easily. You may notice your breath returning, your shoulders softening, your thoughts slowing down, or your ability to connect with another person coming back online.

Gentle Vagus Nerve Practices to Explore

The key word here is gentle. Trauma-informed nervous system work should not feel like forcing, flooding, or overriding your body. If an exercise increases panic, numbness, dizziness, or distress, pause and return to something simpler. You can also explore these practices with a trained therapist.

• Lengthen the exhale. Try breathing in gently and making the exhale slightly longer than the inhale. No need to do it perfectly.

• Hum, sing, or use your voice. Vibration through the throat can be soothing for many people.

• Orient to the room. Slowly look around and name a few neutral or pleasant things you see. This helps your body register the present.

• Notice contact and support. Feel your feet on the floor, your back against a chair, or the weight of a blanket.

• Use safe connection. A regulated voice, a kind face, a pet, a supportive text, or sitting with someone trustworthy can help the nervous system settle.

• Move gently. Walking, stretching, swaying, or shaking out tension can help mobilized energy complete rather than stay trapped. Many people enjoy a gentle exercise routine like Yoga Nidra, or flexibility & Mobility routines.

  
  

A Trauma-Informed Reminder: Your Pace Matters

Some nervous system advice on the internet can sound intense: cold plunges, extreme breathwork, pushing through discomfort, or “hacking” the body into calm. For trauma survivors, more intensity is not always better. Sometimes the most healing intervention is the smallest one your body can actually receive.

You do not have to earn regulation by trying harder. You can begin with one breath, one sound, one moment of noticing, one compassionate check-in with a protective part. Over time, those moments can become pathways your nervous system learns to recognize.

Healing Is Not Just Insight—It Is Felt Safety

Healing often involves both trauma processing and relationship with parts that have worked so hard to protect you from harm. It also involves the body learning, little by little, that the present is different from the past. The vagus nerve matters because it is part of how your body experiences safety, connection, rest, digestion, and recovery; which cannot occur without feeling safe enough.

If your system has been living in survival mode, there is nothing wrong with you. Your body adapted. And with compassionate support, your nervous system can learn new patterns. Therapy can help you move at a pace that honors your protective parts, supports your body, and helps you reconnect with the Self that has been there all along.
