What it means to thaw the nervous system—and reclaim motion when your body goes still

There’s a moment that happens to me in acute crisis that I don’t talk about often. From the outside, it looks like competence. I nod. I listen. I appear calm and composed. But inside, my mind is blank. Not peaceful blank. Not clarity blank. Frozen blank. Thoughts disappear. Words evaporate. Time stretches.

Later, I’ll know exactly what I wish I had said. Later, I’ll understand what needed to happen. Later, my mind will return and organize and analyze and respond. But in the moment, my body has already made its decision.

It freezes.

For much of my life, I felt deeply frustrated by this response. Ashamed of it, even. I wanted to be someone who could access words and clarity in real time. Someone who could respond decisively when it mattered most. Instead, I froze. And I hated that about myself.

The Moment I Felt Seen

There’s a scene in You’ve Got Mail that has stayed with me for decades. Meg Ryan’s character, Kathleen Kelly, is writing an email to the anonymous pen pal (Tom Hanks’ character) she hasn’t yet met in person. She describes what happens when someone says something cruel or hurtful to her face. Her mind goes blank. She can’t respond. She can’t access the words she wishes she had.

But later, always later, the perfect response comes to her. She writes about how frustrating this is. How she wishes she could say those things in the moment. I remember watching that scene and feeling something loosen inside me. Because that was exactly my experience. That moment of blankness. That delay between experience and response. That painful awareness that the words were somewhere inside me, but inaccessible when I needed them most.

I wasn’t weak. I wasn’t incapable. My nervous system was freezing. At the time, I didn’t have that language. I only had frustration and self-judgment. I believed that if I were stronger, smarter, more confident—I would respond differently. But now I understand something I didn’t understand then:

My nervous system wasn’t failing me. It was protecting me.

Understanding the Four Nervous System Responses: Fight, Flight, Freeze, and Fawn

When we encounter threat—whether physical danger, emotional overwhelm, conflict, or uncertainty—our nervous system automatically mobilizes to protect us. This isn’t conscious. It’s biological. Most people are familiar with fight or flight:

Fight says: Confront the threat.
It might look like anger, defensiveness, or taking immediate action.

Flight says: Escape the threat.
It might look like anxiety, urgency, overworking, or avoidance.

But there are two other responses that are just as important—and far less understood:

Freeze says: Become still. Pause. Wait. Survive.

This response slows the system. The mind may go blank. The body may feel heavy or numb. Time can feel distorted.

And Fawn says: Appease the threat to stay safe.
It might look like people-pleasing, over-accommodating, or prioritizing others’ needs over your own.

None of these responses are choices in the traditional sense. They are adaptive survival strategies shaped by our experiences. Our nervous system learns, over time, which response has the highest likelihood of keeping us safe. And then it uses that response, often automatically.

When Freeze Looks Like Competence

Freeze doesn’t always look like collapse. Sometimes, it looks like calm. Sometimes, it looks like professionalism. Sometimes, it looks like someone who is “handling it well.”

I learned early in my life that heavy emotions weren’t always welcome. That moving quickly through feelings made others more comfortable. That composure was safer than expression. And so, my nervous system adapted. It learned to pause. To contain. To hold. To become very, very still.

This was adaptive in environments where emotional expression wasn’t safe, supported, or tolerated. Freeze allowed me to function. To survive. To maintain connection and stability. It protected me. But protection comes at a cost when the response doesn’t complete. Because freeze isn’t meant to be permanent. It’s meant to be temporary. It’s the nervous system pressing pause, not stop.

What Happens When Freeze Doesn’t Resolve

In nature, freeze is often followed by discharge. If you’ve ever watched animals in the wild, you’ll notice something fascinating. After a threat passes, animals often shake. Literally shake. Their bodies release the survival energy that had been mobilized and held. This shaking isn’t dysfunction. It’s resolution. It allows the nervous system to return to baseline.

Humans, however, are often conditioned to suppress this discharge. We override it. We sit still. We keep working. We stay composed. We don’t shake. We don’t move. We don’t release. And so, the energy remains in the body. Unprocessed. Unresolved. Frozen. This can show up later as:

• Persistent anxiety
• Emotional numbness
• Fatigue or exhaustion
• Difficulty concentrating
• Feeling disconnected from yourself
• Or a sense of being “stuck”

Not because something is wrong with you. But because your nervous system never got the signal that it was safe to move again.

Freeze is not failure. Freeze is the nervous system buying time. It’s a protective bridge between overwhelm and safety. The key isn’t to eliminate freeze. The key is to help the nervous system move through it. To gently thaw what became still. To restore motion where there was pause. Not through force. But through movement.

Movement Is Medicine for Freeze

One of the most important things I’ve learned, both professionally and personally, is this:

Movement helps complete the stress response. This doesn’t have to be dramatic. It can be subtle. Gentle. Small. It can look like walking. As I’ve written about before, walking is one of the most powerful ways to regulate the nervous system. The bilateral movement of walking, the rhythmic left-right pattern, helps integrate experiences across the brain and body. When I walk, especially outside, I can often feel my system begin to shift. Thoughts return. Breath deepens. Sensation comes back online. It’s as if my body remembers that it is capable of motion again.

Sometimes it looks like riding my Peloton. Not to push or achieve, but simply to move energy through my system. To remind my body that it isn’t trapped. Other times it’s even smaller than that. Sometimes it’s just shaking my hands. Letting them flutter for a few seconds. This may sound simple, but it works. Because freeze is stillness. And even small movements interrupt that stillness. They send the nervous system a powerful message:

You are not trapped.
You can move.

Gentle Ways to Move Through Freeze

If you recognize yourself in freeze, here are some gentle ways to help your nervous system thaw.

1. Start small

You don’t need to force big movement. Wiggle your fingers. Roll your shoulders. Shake your hands. Small movement is still movement.

2. Walk without urgency

Not for exercise. Not for productivity. Just walk. Let your body set the pace. Notice your surroundings. Notice your breath.

3. Shake it out

Literally shake your arms, your hands, your legs. This mimics the natural discharge process animals use to resolve threat. It may feel awkward. That’s okay. Your nervous system understands it.

4. Change your environment

Step outside. Shift rooms. Alter your sensory input. Novelty signals safety to the brain.

5. Breathe and move together

Pair gentle movement with slow breathing. This helps re-engage the parasympathetic nervous system, the system responsible for restoration and calm.

The Deeper Work: Compassion for the Freeze Response

Perhaps the most important part of this process isn’t the movement itself. It’s the compassion. Freeze developed for a reason. It was intelligent. Adaptive. Protective. It helped you survive environments that required stillness. The goal isn’t to judge it. The goal is to thank it. And then gently help your nervous system learn that movement is now safe.

This takes time. It takes repetition. It takes patience. But it is possible. I know because I’ve lived it. I still freeze sometimes. But I no longer interpret it as failure. I interpret it as information. A signal from my nervous system that something feels overwhelming.

And instead of shaming myself, I move. I walk. I shake my hands. I step outside. I let the response complete. And eventually, motion returns. So does clarity. So does choice.

Fear will always be part of being human. The goal isn’t to eliminate fear. The goal is to keep it from becoming permanent stillness. To allow the body to pause when needed. And then to gently help it move again. Because freeze isn’t where the story ends. It’s just where motion paused. And motion can return. One small movement at a time.

What I’m Loving This Week

Sound:
The sound of birds in springtime. Outside my work window, there’s a mama bird I’ve named Charlie, and she has a lot to say these days. Her steady chatter reminds me that life continues. That motion continues. That instinctively, living beings know how to respond to their environment and keep moving forward.

Practice:
Movement. Walking outside or riding my Peloton, not to achieve, but to release. To allow stress to move through my body instead of staying trapped within it.

Tool:
Quick shake-outs with my hands. Just a few seconds of shaking helps interrupt the freeze response and reminds my nervous system that I am not stuck.

Song:
Comfortably Numb — Pink Floyd
I first heard this song on a mixed tape in college, and it immediately resonated, the strange familiarity of numbness, and the quiet longing underneath it. The desire not just to survive, but to feel again.
