The Fight, Flight, Freeze Response:  How Somatic Approaches Can Help Regulate Your Nervous System

Woman in nature

Have you ever felt a rush of adrenaline when faced with a sudden threat? Or found yourself reacting in a way that surprised you—snapping at someone, shutting down, or feeling the urge to run?

These are all natural reactions tied to your body’s built-in stress response, commonly known as the fight, flight, or freeze response. When your body thinks that it is in danger, it triggers a set of reactions to protect itself in the form of staying and fighting or fleeing the danger. Freezing is another stress response in which your body goes into a hold in order to protect itself from perceived danger, it is also known as reactive immobility or attentive immobility.

In this post, we’ll explore how this survival response works, why it shows up even when you’re not in danger, and how somatic therapy can help bring your nervous system back into balance.

What Is the Fight, Flight, Freeze Response? 

Whenever you meet a stressful situation, your body releases a hormone called cortisol. It is also often known as a “stress hormone” that triggers your body’s natural fight-or-flight response. However, freezing is also a common response to threats that is driven by the parasympathetic nervous system. If you are getting confused, let us explain in simpler terms.

Your Autonomic Nervous System consists of a Sympathetic and a Parasympathetic Nervous System. The way you react to stress depends on which system dominates the response during stress. 

 Fight Response 

The fight response is driven by the sympathetic nervous system. The fight response is triggered when your body perceives the threat as something that you can overpower. This is when your brain sends a signal to your body and prepares for the fight. 

Flight Response 

When your body cannot overpower the threat, the other response is to flee and protect yourself from the danger. The rush of cortisol and adrenaline gives your body extra stamina to run from the threat longer than you normally can. 

Freeze Response 

However, your stress response is a little bit more complex than just fight-or-flight. Your body can also freeze to threats and danger if your brain cannot decide between fleeing and fighting. This happens when the danger is too overwhelming for your body, causing a complete shutdown followed by numbness and dissociation from reality. 

Why Do People React to Stress So Differently?

You can understand the flight-fight-freeze response with the help of a simple example. Imagine you see a monster under your bed. Now you have three options:

  • You can fight and defeat the monster to eliminate the danger. This is called the fight response 
  • You can flee and ask for help to protect yourself from the danger. This is the flight response 
  • Or you can close your eyes and pretend the monster doesn’t exist. This is the freeze response where you disassociate from reality to protect yourself. 

The reason why some people react differently to stress depends on many factors such as: 

  • Past Trauma: If you have experienced trauma or abuse in your life, your brain might freeze as the default stress response. This is because your brain hasn’t been trained to make decisions and is too overwhelmed when met with a threat. 

  • Personality: Your upbringing, environment, and temperament all influence how you handle conflict and pressure. Some people move toward challenge (fight), some retreat (flight), and others become still or emotionally numb (freeze).

  • Nervous System Regulation: Some people naturally return to baseline more easily after stress, while others stay stuck in high alert or shutdown. This ability to “bounce back” is called nervous system regulation, and it plays a key role in emotional resilience.

Signs Your Nervous System Might Be Dysregulated

If your nervous system has difficulty shifting out of survival mode, you might notice signs such as:

  • Feeling chronically anxious or overwhelmed
  • Trouble relaxing or falling asleep
  • Irritability, outbursts, or panic
  • Avoidance, procrastination, or low motivation
  • Numbness, dissociation, or a sense of being “checked out”

These signs aren’t just “in your head,” they’re clues from your body that it’s working hard to keep you safe, even when the danger has passed.

How Somatic Therapy Can Help You Regulate Your Nervous System

When you’ve lived in a prolonged state of stress, simply talking about what’s going on may not be enough to shift your internal state. That’s where somatic therapy comes in.

Somatic approaches help you reconnect with your body, gently release stored tension, and support your nervous system in feeling safe again. They work from the “bottom up,” using the body as the entry point for healing.

Here are a few somatic tools that can help you move out of a fight, flight, or freeze response:

Progressive Muscle Relaxation: This technique involves tensing and then slowly releasing different muscle groups. It helps release tension and signals to your body that it’s safe to relax.

Grounding Technique: When you are in a flight response, you lose the sense of reality. Grounding can bring you back to reality and make you more aware of your surroundings. You can connect with the earth and feel its energy filling your body. A lot of people do this exercise outside with their feet on the ground. 

You can start doing this by 5-4-3-2-1 Method (Name 5 things you see, 4 things you touch, 3 things you hear, 2 things you smell, 1 thing you taste).

Somatic Movement and Gentle Exercise: Sometimes, breathing exercises cannot release stuck negative energy. Slow somatic movements, yoga, and gentle mindful dancing can help you reconnect with your present and unstuck yourself from all the negative emotions and trauma. 

Vagus Nerve Simulation: The vagus nerve is the longest cranial nerve in the body, running from the brainstem down to the heart, lungs, and digestive system. Splashing cold water on your face, humming, and deep exhalations can activate the vagus nerve, shifting the body from a fight-or-flight response. 

If you’ve been living in a state of tension, panic, or shutdown, it doesn’t have to stay that way. Healing the nervous system is possible, and somatic therapy offers gentle, effective tools to support that process.

At Breakthrough Counselling, we offer somatic therapy in Montreal for teens and adults who want to reconnect with their bodies, release stored stress, and feel more grounded in everyday life.

If you’re curious about whether somatic approaches could support your healing, we invite you to reach out. You don’t have to figure it out alone.
