The Impacts of Trauma: Why it’s Important to Heal the Sympathetic Nervous System State Through Trauma Therapy

I want to talk to you today about the sympathetic nervous system state. The sympathetic nervous system state is one that I think, unfortunately, many of us in the United States are in almost all the time. We are so busy, we are moving a million miles a minute, we're trying to accomplish all the tasks and all the things.

I know for me, as a woman with a career and a child, I feel like I am constantly on the go, trying to keep up, trying to take care of things and people and aspects of my job and home, trying to manage responsibilities that are so overwhelming that I don't slow down and breathe. When I'm in this state, I'm in a high state of anxiety, with cortisol pumping through my veins. I'm in a high state of stress.

I can experience panic, and have physical symptoms such as tightness in my stomach, feeling nauseous from time to time, and feeling flushed on my skin, with feelings of fear and all-around being uptight.

It can become hard to connect with others. It's hard to be present. It's difficult to listen as well as I would like, because I'm thinking about and trying to accomplish so many different tasks. For someone who's experienced trauma, hypervigilance and being on edge and slipping into this sympathetic state is almost the default mode after the traumatic event, which is why sorting through your triggers in trauma therapy is so important.

Key Definitions

What Is the Sympathetic Nervous System?

The sympathetic nervous system is the branch of the autonomic nervous system that gets your body ready to respond to danger, real or perceived. It's the part behind the fight-or-flight response, and it gears your body up for action when things get stressful.

What Is Hyperarousal?

Hyperarousal happens when your nervous system stays switched on and alert. It often looks like anxiety, racing thoughts, muscle tension, irritability, trouble sleeping, restlessness, and feeling constantly "on edge."

What Is Trauma?

Trauma happens when experiences overwhelm a person's ability to cope and keep affecting their emotional, physical, relational, or psychological well-being long after the event is over.

What Is Nervous System Dysregulation?

Nervous system dysregulation is when your body has a hard time getting back to balance after stress. People can get stuck in hyperarousal, shutdown, emotional overwhelm, or constant activation.

What Is Nervous System Regulation?

Nervous system regulation is the ability to move flexibly between activation and calm while staying connected to yourself, others, and the present moment.

That's why many people who've experienced trauma stay on edge. They may be constantly aware of their surroundings. They might hear a loud noise and jump. They might feel like they can't settle in or relax in a room. Trauma can change how the nervous system responds, and that affects both the brain and the body.

This has been linked to health problems such as ischemic heart disease, sleep problems, increased risk of suicidality and depression, increased risk of substance abuse and lung cancer and diabetes.

When we experience trauma in our lives, and many of us have experienced trauma in our lives at some point, it can disrupt our hormonal system, our bodies, our brain, and it can take a real toll on our health. Gaining awareness around this issue and seeking the help you need can support your health and your life, and that can benefit the people around you.

Because we can't put an oxygen mask on someone else first, in case we pass out. We have to put the oxygen mask on ourselves first in order to be effective and helpful to others. I wanted to share my thoughts on the sympathetic nervous system and how this state can be activated, as well as the importance of getting the help and treatment that we need so that the sympathetic state does not become our default mode. We have to calm our nervous systems down in order to be open, functioning, and helpful humans.

Teens, Trauma & the Sympathetic Nervous System

Trauma doesn’t only affect adults. It affects children and teens, too. Adolescence is already a time of rapid change - hormonal, neurological, social. For a teen who’s been through trauma, the added weight of a sympathetic nervous system that’s always switched on can make everything feel harder: sleep, learning, friends, home life. In these young bodies, repeated stress and threat signals aren’t just mental - they affect the developing brain and body. For example, trauma in childhood or adolescence is tied to prolonged activation of the sympathetic nervous system (“fight/flight”), which puts ongoing stress on the body and nervous system. St. David’s Center

What this looks like in a teen:

• A pattern of feeling “on edge” or hyper-alert, as though danger could show up at any moment.
• Mood swings, irritability, or sudden emotional outbursts over seemingly small triggers. This fits with research showing that trauma can narrow a person’s “window of tolerance,” so minor stressors set off big responses. Verywell Mind
• Constant fatigue or shutdown: after a stretch of high arousal, the body may collapse into a “freeze” mode, or simply feel worn out all the time.
• Trouble concentrating, up-and-down school performance, disrupted sleep, and pulling away from friends or family. For teens, one health resource lists: “disturbed sleeping patterns; withdrawal from family and friends; being very protective of family and friends; loss of interest in school, friends, hobbies and life in general.” Better Health Channel
• Physical complaints: headaches, stomachaches, muscle tension - because the body is literally responding to chronic threat by keeping the sympathetic system engaged. Asteroid Health

How Counseling Helps Teens Regulate & Heal

• Paced, trauma-informed approach: A counselor trained in trauma works with the teen’s nervous system first - helping them understand what’s going on in their body (not just their “feelings” or behavior). That means teaching grounding, breathing, safe posture, and ways to slow the sympathetic activation. Trauma-informed counseling for teens takes specific training and a specific approach.
• Building a new “baseline”: As healing happens, the goal is for the sympathetic nervous system to stop getting stuck in “emergency mode.” Instead, the teen learns to shift toward states of safety, connection, and rest (parasympathetic / ventral-vagal states).
• Integrating brain + body: Because the teen brain and nervous system are still developing, the right support can help change how threat signals are processed. Untreated trauma in adolescence has been associated with lasting effects on brain regions like the amygdala, hippocampus, and prefrontal cortex. ScienceDirect, which is why trauma therapy is so important.
• Supporting identity & connection: Teens often feel isolated or “different” because of how trauma affects their responses. Counseling offers a place to explore how trauma shaped their sense of self, why they might push people away or act out, and how to take their life back moving forward. Their responses reflect how trauma has affected their nervous system. Counseling for teens with a trained professional can help them build awareness and connection.
• Parent and family support: Trauma-responsive counseling for teens often includes talking with parents/caregivers about nervous system regulation, how to respond when the teen is dysregulated, and how to build a home that supports safety rather than triggers.

Anxiety and Chronic Fight-or-Flight

Anxiety is closely tied to sympathetic nervous system activation. You might notice racing thoughts, constant worry, muscle tension, an upset stomach, sleep problems, panic symptoms, or a nagging sense that something bad is about to happen.

When the nervous system spends long stretches in fight-or-flight, everyday stress can feel like too much. The brain gets more and more focused on spotting threats and guarding against danger.

Anxiety therapy can help clients understand how their nervous system feeds their anxiety. Through CBT, ACT, mindfulness practices, grounding exercises, breathwork, and nervous system regulation strategies, clients learn ways to bring activation down and become more emotionally flexible. The goal is a nervous system that can respond to what's actually happening instead of staying on high alert all the time. Eliminating all stress isn't the aim.

Depression, Burnout, and Chronic Activation

Depression and anxiety can look like opposites, but being stuck in sympathetic activation for a long time can contribute to exhaustion, burnout, and depression. When your body spends too much time mobilized for survival, you run out of emotional and physical fuel.

You might feel fatigue, hopelessness, irritability, low motivation, numbness, or like you have nothing left to give.

Depression therapy helps you understand how chronic stress, trauma, and nervous system dysregulation may be feeding your symptoms. Therapy often focuses on getting back to balance, rebuilding connection, growing self-compassion, and finding ways of meeting life's demands that you can keep up over time.

ADHD and Sympathetic Nervous System Overload

Many people with ADHD spend a lot of time in sympathetic activation. Executive functioning struggles, sensory overwhelm, time pressure, perfectionism, and chronic stress can leave the nervous system feeling switched on all the time.

That often shows up as emotional reactivity, task paralysis, trouble focusing, procrastination, and cycles of overwhelm followed by burnout.

ADHD therapy helps you understand how executive functioning and nervous system regulation affect each other. Therapy can offer practical ways to cut down on overwhelm, manage emotions and stress, and be kinder to yourself about ADHD-related struggles.

Postpartum Mental Health and Hypervigilance

The postpartum period asks a lot of the nervous system. Hormone shifts, sleep deprivation, new responsibilities, identity changes, and worries about a baby's safety can all push sympathetic activation higher.

Some parents deal with constant worry, hypervigilance, racing thoughts, irritability, panic symptoms, or trouble relaxing even when they finally get a chance to rest.

Postpartum therapy helps parents understand these experiences through a trauma-informed and compassionate lens. Therapy can support nervous system regulation, ease shame, build coping skills, and strengthen emotional well-being during this big life transition.

LGBTQIA+ People and Chronic Stress

Many LGBTQIA+ people live with chronic activation because of minority stress, discrimination, rejection, bullying, hiding who they are, or fears about safety and acceptance.

Over time, this can lead to more anxiety, hypervigilance, emotional exhaustion, and nervous system dysregulation.

LGBTQIA+ affirming therapy helps you work through discrimination and identity-based stress while building self-acceptance, resilience, emotional safety, and supportive relationships. Healing often means helping the nervous system experience being authentic and connected without fear.
