Trauma and Nervous System Dysregulation
Understanding why you feel stuck—and how to come back home to yourself.
If you’ve ever thought, “Why can’t I just calm down?” or “I know I’m safe, but my body doesn’t feel safe,”—you’re not alone. These are signs that your nervous system isn’t dysregulated because you’re weak. It’s dysregulated because it’s wise—and it learned to protect you.
Let’s unpack how trauma and nervous system patterns affect your HPA axis and your healing.
What Happens When We’re Under Threat
Your brain and body are beautifully designed to respond to danger. When your nervous system senses threat (real or perceived), your HPA axis kicks in:
- Hypothalamus: alerts you
- Pituitary: signals your adrenals
- Adrenals: release cortisol to help you fight, flee, or freeze
This is helpful in the moment… but not when it gets stuck in “on” mode for days, weeks, or years.
Unresolved trauma—especially when it happens early or repeatedly—can trap your body in survival mode. You may feel:
- Hypervigilant (startling easily, racing thoughts)
- Numb or flat (can’t feel joy or sadness)
- Emotionally reactive (big emotions over small things)
- Exhausted (even with sleep)
This is a nervous system dysregulation loop, and it deeply affects your hormones, gut, and energy.
How Polyvagal Theory Helps Us Understand Healing
Polyvagal theory shows us that the nervous system has more than just “fight or flight”:
- Ventral vagal = safe, social, regulated
- Sympathetic = mobilized, anxious, activated
- Dorsal vagal = shutdown, numb, disassociated
Healing isn’t just about calming down—it’s about learning to move between these states, reconnecting to safety over time.
Somatic Tools That Support Regulation
You can’t “think” your way out of trauma. But you can help your body feel safe again.
Here are a few practices to try:
- EFT Tapping: gently tapping acupoints while speaking truths (“Even though I feel overwhelmed, I am safe right now”)
- TRE (Tension & Trauma Release Exercises): allows the body to shake off stored tension
- Grounding: press feet into the floor, hold a warm mug, name 5 things you see
- Vagus nerve practices: hum, gargle, sing, Auriculotherapy, or use long exhales to activate your calm system
The goal isn’t perfection. It’s pattern recognition—and gentle redirection.
Safe Connection Is Medicine
One of the most profound ways to rewire the nervous system is through safe, attuned relationships. Whether with a friend, partner, therapist, or group, we regulate through co-regulation first—then self-regulation becomes possible.
If you’ve been healing alone, I want to encourage you: you don’t have to do this by yourself anymore.
You’re Not Broken—You’re Brilliant
Your survival system did its job. But now you’re ready to write a new story. One where your body doesn’t live in the past, and where safety becomes your new normal.
Ask yourself:
“What helps me feel safe in my body?”
Write it down. Practice it daily. Let safety become your foundation—not a luxury.
