Growing Up with Trauma: How Trauma Affect Your Nervous System—and How to Finally Heal

Have you ever wondered why your body reacts so strongly to stress or why certain situations make you feel anxious, tense, or even disconnected? For many people who grew up with difficult or traumatic experiences, these feelings are more than just emotional—they’re rooted in the way the nervous system learned to protect you.

Childhood trauma isn’t just about what happened years ago. It’s about how those experiences shaped your brain and body, affecting how you feel, think, and respond to life, even years later. It can be disheartening to realize how many of our current responses are related to subconscious memories of past trauma, but on the either hand understanding where it comes from gives us possibilities for healing. The nervous system is flexible, and with the right support and tools, you can learn to feel calmer, safer, and more present and connected.

Lets look at how trauma affects your nervous system, what science says about these changes, and how therapies like neurofeedback, EMDR, grounding exercises, mindfulness, and more can help you find relief and hope.

1. What Is Childhood Trauma?

Childhood trauma can mean many things: abuse, neglect, losing someone important, witnessing violence, or living through constant stress. Even living in a home with frequent parental yelling or unpredictable periods of mild neglect (no one making meals, or available to help with school work or talk to about problems) can be experienced traumatically by many children with more sensitive personality styles. The famous Adverse Childhood Experiences (ACEs) study found that these experiences are common and can have long lasting negative effects.

What matters most is not just the event, but how it made you feel at the time, how you coped and whether you had someone to confide in and give you a sense of security and hope for the future. Every person is different, and trauma looks different for everyone.

2. The Nervous System: Your Body’s Alarm System

Your nervous system is like your body’s control center. It helps you react to things around you—sometimes by getting you ready to fight or run away (the “fight or flight” response), and other times by helping you relax and recover.

When you grow up with trauma, your nervous system can get stuck in “alarm mode.” Instead of calming down when the threat is gone, your body stays tense, alert, and ready for danger—even when there’s none. This leaves you feeling anxious, overwhelmed, tense or restless most of the time.

3. How Trauma Changes Your Brain and Body

A. Stress and the Brain

Studies show that ongoing stress in childhood changes the way the brain develops. Important parts of the brain can become overactive or underdeveloped:

• Amygdala: This is your brain’s “alarm bell.” Trauma can make it extra sensitive, so you feel threatened more easily.

• Hippocampus: This area helps with memory and learning. Chronic stress can shrink it, making it harder to focus or remember things.

• Prefrontal Cortex: This part helps you make decisions and control impulses. Trauma can make it harder to manage emotions and actions.

B. Stress Hormones

Your body’s stress system releases hormones like cortisol to help you deal with danger. If you grow up with trauma, your body may release these hormones too often, leading to:

• Trouble sleeping

• Difficulty concentrating and feeling present

• Feeling anxious or jumpy

• Physical health problems, including autoimmune disorders

C. The Body Remembers

Trauma isn’t just in your mind—it’s in your body. Many people have:

• Chronic pain

• Stomach or digestive issues

• Headaches

• Other unexplained health problems

These symptoms are real and connected to how your nervous system learned to protect you.

4. Signs That Trauma Has Affected Your Nervous System

If you grew up with trauma, you might notice:

• Always on alert: Easily startled, tense, or worried

• Emotional ups and downs: Trouble managing feelings, depression, anxiety or mood swings

• Feeling numb or disconnected: Sometimes you feel “checked out” or not fully present

• Sleep problems: Nightmares, trouble falling or staying asleep, difficulty with “deep” sleep

• Physical symptoms: Headaches, stomachaches, TMJ and aches and pains with no clear cause

These are your body’s ways of coping with stress—they helped you survive, but they can make life harder now.

5. Healing Your Nervous System: How Therapy Can Help

The brain and nervous system can change and heal, no matter your age. Therapy can help you process trauma as well as learn new ways to feel emotionally safe and calm. Here are some of the most helpful approaches:

A. Neurofeedback: Training Your Brain for Calm

Neurofeedback is a therapy that uses sensors to measure your brainwaves. We measure your brain waves and work towards enhanced self-regulation on a brainwave level.

Over time, your brain learns to move out of “alarm mode” and into more balanced states. Studies show neurofeedback can help with anxiety, PTSD, sleep and attention problems.

B. EMDR: Processing Traumatic Memories

EMDR (Eye Movement Desensitization and Reprocessing) is a therapy that helps you process difficult memories. You focus on a memory while following the therapist’s finger or another moving object with your eyes. This helps your brain “digest” the memory so it’s less upsetting.

EMDR is well-researched and a gold-standard recommended therapy for trauma. It can help you feel less stuck, and more in control of thoughts and feelings. flashbacks, negative self talk, critical and hopeless internal voices are all usually dramatically reduced through EMDR. EMDR helps us unlearn the internalized sense of worthlessness or “not enough”ness we internalized from our trauma and replace it with a sense of empowerment and appreciation of our internal stregths.

C. Grounding Exercises: Bringing Yourself Back to the Present

Grounding exercises help you reconnect with your body and the present moment, especially when you feel overwhelmed or disconnected.

Some examples:

• 5-4-3-2-1 Technique: Name five things you see, four you can touch, three you hear, two you smell, one you taste.

• Body scan: Focus on each part of your body, noticing sensations.

• Deep breathing: Slow, deep breaths can help you relax.

These exercises are simple but powerful ways to calm your nervous system. Practicing these in therapy makes them easier to use at home.

D. Mindfulness: Being Present Without Judgment

Mindfulness means paying attention to your thoughts, feelings, and body sensations without judging them. For trauma survivors, mindfulness helps break the cycle of worry and stress.

Mindfulness practices can include:

• Meditation

• Mindful breathing

• Paying attention to your senses

Research shows mindfulness can reduce PTSD symptoms and improve mood.

E. Other Helpful Therapies

• Trauma-Informed Care: Trauma informed therapy can also include cognitive behavioral work to identify and change damaging thoughts, self-critical and shaming thought loop cycles, and unhealthy attachment and behavior patterns that developed from traumatic life circumstances. Good therapy shows respect for your background, personality and experiences, has a collaborative feel and helps you feel increasingly more empowered as you learn coping skills and move towards self-compassion and confidence.

7. Healing Is Possible: Stories of Change

Many people who grew up with trauma find relief and hope through therapy. They learn to:

• Recognize and soothe their body’s alarm signals

• Build new, healthier ways of thinking and feeling

• Connect more deeply with themselves and others

You too can feel more at home in your body and more present in your life!

8. Community and Connection Matter

Healing isn’t just about therapy—it’s also about support from others. Sometimes family therapy, support groups or online communities can be valuable in helping you feel less alone and more understood.

Having caring people around you makes a big difference in how you feel and how your nervous system recovers. If you haven’t attracted truly good people into your orbit, you are likely to find that therapy helps you weed out toxic relationships and develop more personal relationships where you feel valued.

9. Everyday Practices for Healing

You can support your nervous system every day by:

• Creating safe spaces: Use calming objects, scents, or music.

• Having routines: Regular sleep, meals, and self-care help you feel stable.

• Practicing self-compassion: Be gentle with yourself and remember your reactions are normal.

• Expressing yourself: Art, music, writing, or movement can help process emotions.

• Moving your body: Exercise, yoga, or walking can release tension and boost mood.

10. Medication and Medical Support

Sometimes, medication can help with anxiety, depression, or sleep problems. It’s not a cure, but it can make therapy and healing easier. Neurofeedback and supplements are all-natural ways of helping your brain heal as well. We are strong advocates of utilizing natural self-regulation resources when possible and collaborate with you and any other treatment providers you’d like, so that you can work on healing more completely.

11. Helping Children Heal

If you’re a parent or caregiver, you can help a child with trauma by:

• Providing routines and clear boundaries

• Responding with empathy and patience

• Encouraging safe expression of feelings

• Offering grounding and mindfulness activities

• Seeking professional support when needed

Early help can make a big difference.

12. When to Seek Help

If you have:

• Nightmares, flashbacks or avoidance

• Anxiety or depression

• Trouble functioning at work, school, or in relationships

• Self-harming behaviors or substance misuse

It’s time to reach out to a therapist. You don’t have to do this alone.

13. Resilience: Your Strength

Resilience means being able to adapt and grow, even after difficult experiences. Your nervous system can learn new ways to feel safe and connected. Many trauma survivors develop strengths like empathy, creativity, and determination.

14. Rewriting Your Story

Trauma may have shaped your nervous system, but it doesn’t define you. With the right support, you can heal and create a new story for yourself—one of hope, connection, and resilience.

Therapies like neurofeedback, EMDR, grounding, mindfulness, and others can help you reclaim your life. Reaching out for help is the first step, and healing is possible.
