Have you ever been in the middle of a difficult conversation or a high-pressure workday and suddenly felt like your brain just… unplugged? You didn’t yell, and you didn’t run away. Instead, you simply went quiet. Maybe your limbs felt heavy, or you found yourself staring at a blinking cursor while your mind went completely blank.
It’s a strange, often lonely place to be. But that “shutdown” isn’t a flaw in your character; it’s actually your body’s most sophisticated way of trying to protect you. This biological survival mechanism is known as the freeze response. If you’ve ever felt frustrated for “going numb” when you thought you should be “taking action,” it’s time to be a little kinder to your nervous system. You aren’t being lazy. You’re experiencing a reflex that’s just as real as any other physical defense.
Save this for later
You might want to refer back to these steps the next time you feel your “internal circuit breaker” start to trip.
Beyond Fight-or-Flight: The Three Gears of Survival
Most of us are familiar with the fight-or-flight response. We know the racing heart of anger or the urge to bolt when we’re scared. However, according to the Polyvagal Theory developed by Dr. Stephen Porges, our nervous system has a third, deeper gear. When fighting or running away isn’t an option, the body resorts to the freeze response.
Think of your nervous system like a house with a complex electrical grid. When the “demands” on your energy become too much for the wires to handle, your body doesn’t want to risk a fire. To save the system, it trips a circuit breaker. In biology, this is called dorsal vagal shutdown.
Understanding the Freeze response through Polyvagal Theory
While other responses are about using energy to survive, the freeze response is about conserving it. Your brain has essentially decided that neither fighting nor running will work, so it “plays dead” to stay safe. This state is experienced by 20–30% of trauma survivors and is a core feature of about 10–15% of clinical burnout cases.
Why “Going Blank” is a Valid Trauma Response
We live in a culture that prizes “powering through,” so when we shut down, we often feel a secondary layer of shame. The NIH and the Mayo Clinic emphasize that chronic stress can actually change how our brain processes threats. When your system is overwhelmed, emotional numbing or dissociation acts as a psychological buffer—a biological heavy blanket that dulls the pain of a situation that feels too big to handle. Using the freeze response as a buffer is a natural part of survival.
Dissociation is a common symptom in roughly 40% of complex trauma cases and is a recognized criterion for PTSD. During a shutdown, the parts of your brain responsible for logic and speech—the prefrontal cortex—receive fewer resources. Your body focuses instead on keeping your vital organs functioning in a “low-power mode.” This shift is why many people experience the freeze response during highly volatile social or professional situations.
“I just went blank” is a physiological reality, not an excuse. For the 4.4% of adults living with ADHD, this vulnerability to shutdown is often even higher. Their brains are already working overtime to manage daily stimulation, making the freeze response a more frequent occurrence when the “circuit breaker” trips under pressure.
The Difference Between High Stress and Dorsal Vagal Shutdown
It’s helpful to distinguish between regular stress and a true freeze response. Stress usually feels high-energy—jittery, anxious, or irritable. Shutdown feels low-energy and stagnant. You might notice a feeling of being “spaced out” or disconnected from your surroundings, which is indicative of the freeze response.
Physical heaviness in your limbs, like you’re moving through water, is another hallmark. You might experience a sudden drop in heart rate or “flat,” muted emotions. For many, this is what emotional burnout actually looks like. With 1/3 of the global workforce currently facing burnout according to the WHO, severe shutdown is becoming a common proxy for extreme exhaustion. If left unaddressed, the persistent freeze response can increase the risk of depression by 2.5 times.
Practical Ways to Regulate Your Nervous System
If you find yourself stuck in a freeze response, criticizing yourself will only keep your “circuit breaker” tripped. Self-judgment is a “threat” signal to the brain. Instead, try these gentle, evidence-based strategies for vagus nerve stimulation to signal safety:
- Change Your Temperature: The CDC and various experts suggest a sudden temperature shift can “shock” the system back into the present. Splashing ice-cold water on your face can increase vagal tone and heart rate variability (HRV) by 15–20%, helping to interrupt the freeze response.
- Gentle, Mindful Movement: Since the freeze response is characterized by stillness, small movements help. Don’t try to go for a run; just wiggle your toes or circle your ankles. These tiny actions tell your brain: “I am moving, I am safe, and I am here.”
- The “Voo” Breath: Stemming from polyvagal-informed practices, making a low-frequency sound like “Voo” on a long exhale creates a vibration in your chest. This physically stimulates the vagus nerve and can increase HRV by 10–15%, sending a direct message to your brain to end the freeze response.
A Narrative of Compassion
Your body is not your enemy. Even when it shuts down at an “inconvenient” time—like during a meeting or a disagreement—it’s doing so out of a deep, ancient desire to keep you alive. While researchers sometimes debate the specific pathways of the polyvagal framework, the experience of a freeze response as a protective measure is widely recognized in clinical psychology.
By naming the freeze response, you take away its power. You aren’t “broken”; you’re well-defended. However, if you find yourself in this state persistently for more than two weeks, it’s a sign that it’s time to seek a professional screening for anxiety or burnout.
The next time you feel that mental blankness, take a breath and recognize the freeze response. Acknowledge that your body is trying to protect you, and take your time coming back. You aren’t just waiting for the fog to lift; you’re learning the language of your own resilience. Understanding the freeze response is the first step toward reclaiming your agency. You’ve got this.
FAQS
What is the freeze response and why does it happen?
The freeze response is a survival mechanism where the nervous system “shuts down” to conserve energy when fighting or running isn’t possible. According to Polyvagal Theory, this dorsal vagal shutdown acts like an internal circuit breaker, protecting the body from overwhelming stress by entering a low-power, “playing dead” state.
What are the common symptoms of a dorsal vagal shutdown?
Symptoms of a dorsal vagal shutdown include feeling “spaced out,” disconnected, or emotionally numb. Physical hallmarks often include heavy limbs, a sudden drop in heart rate, and “flat” emotions. Individuals may also experience a mental blankness, finding it difficult to find words or finish thoughts during high-pressure situations.
How can you use vagus nerve stimulation to stop a freeze response?
You can interrupt a freeze response by signaling safety to the brain through vagus nerve stimulation. Effective methods include splashing ice-cold water on the face to increase heart rate variability, performing tiny mindful movements like wiggling toes, or using the “Voo” breath to create chest vibrations that stimulate the vagus nerve.
When should a persistent freeze response be considered a medical concern?
While the freeze response is a natural defense, being in this state persistently for more than two weeks is a red flag. It can indicate severe emotional burnout or increase the risk of depression. In such cases, the article recommends seeking professional screening for anxiety, PTSD, or burnout.
Why is “going blank” considered a valid trauma response?
“Going blank” is a physiological reality where the prefrontal cortex—responsible for logic and speech—receives fewer resources during a shutdown. The body redirects energy to vital organs for survival. This dissociation or emotional numbing acts as a biological buffer against overwhelming stress, common in PTSD and complex trauma cases.
