Signs Your Nervous System Is Dysregulated (And What to Do About It)

For years, I thought the way I felt was a character flaw. The hypervigilance, the inability to fully relax even in safe environments, the swinging between emotional flooding and complete numbness — I thought I just needed more discipline. More willpower. A better morning routine. If I could just get myself together enough, I'd be fine.

What I actually had was a nervous system that had been running in survival mode for so long it had forgotten what safety felt like. Eight years in the military, a deployment to Kuwait and Iraq, years of fighting the VA for a PTSD claim — my system had been in threat-response mode almost continuously. It wasn't a mindset problem. It was a physiological state. And physiological states don't respond to willpower.

A Map of the Nervous System

Your autonomic nervous system has three primary states, based on Polyvagal Theory developed by Dr. Stephen Porges. Understanding these changed how I understood myself:

• Ventral vagal (safe and social) — calm, connected, present; you can think clearly, relate to others, feel yourself in your body
• Sympathetic activation (fight or flight) — alert, agitated, anxious, reactive; scanning for threat even in its absence
• Dorsal vagal (freeze and shutdown) — numb, dissociated, flat, exhausted; checked out from the inside

All three states serve a purpose. The goal is not to eliminate the survival states — it's to have flexibility: to move between states as the actual situation requires, rather than getting anchored in survival mode as a default.

Dysregulation is when the system loses that flexibility. When hypervigilance or shutdown become your resting state — not because of any present threat, but because your nervous system learned threat as its baseline.

Signs You Might Be Dysregulated

On the hyperactivated (fight/flight) end:

• Chronic anxiety or sense of dread without a clear cause
• Startling easily; staying alert even in genuinely safe environments
• Mind that won't quiet, especially at night
• Irritability or emotional reactivity that feels disproportionate
• Tight jaw, raised shoulders, shallow chest breathing you don't notice until someone points it out

On the shutdown (freeze/dorsal) end:

• Emotional flatness — difficulty feeling much of anything
• Fatigue that sleep doesn't fix
• Difficulty making decisions or connecting to what you want
• Dissociation — watching your life from a slight distance rather than living it
• Social withdrawal that isn't preference — it's depletion

These are not personality flaws. They are not weakness. They are physiological patterns your body developed to keep you alive. And physiological patterns can change.

Where to Start

My number one mission is to help people feel safe in their bodies so they can feel safe in the world. That work starts here — with the most direct access point to nervous system state: the breath. Specifically the exhale.

The vagus nerve — which mediates the parasympathetic response, the calming system — is activated most powerfully by slow, extended exhales. Try this: inhale for a count of 4. Exhale for a count of 7 or 8. Notice what happens in your body at the bottom of the exhale. That small drop in tension, that slight softening — that is your parasympathetic system engaging. That is safety signaling to your nervous system in a language it understands.

Do that five or six times. That is not a mindfulness exercise. That is a direct physiological intervention. And it works.

Other accessible starting points:

• Cold water on the face or wrists — activates the dive reflex and slows heart rate
• Humming, singing, or even sighing — stimulates the vagus nerve through vocalization
• Orienting — slowly scanning the room and naming what you see, signaling to your system that you are, in fact, present and safe
• Rhythmic movement — walking, rocking, swinging — helps the nervous system discharge and reset

None of these are cures. They are entry points. Every time you use them and they work, you're teaching your nervous system that regulation is possible. That safety is possible. We honor nervous systems and timelines — there is no correct pace for this. There is only the next small moment of returning to yourself.

That is how change happens. One breath at a time, one moment at a time. Resilience. Healing. One day at a time.
