Have you ever found yourself feeling anxious or panicked, even when you’re not in immediate danger? Maybe your heart races, your chest tightens, your stomach churns, and your thoughts spiral out of control. You might feel like you’re constantly on edge, as though your body is bracing for something terrible—even when you’re just standing in line at the supermarket or trying to fall asleep.
That’s the fight-or-flight response—your nervous system’s built-in alarm system, designed to protect you from danger. It’s incredibly useful in a life-or-death emergency… but not so helpful when it gets stuck in the “on” position.
The good news? You can learn how to calm your nervous system and step out of survival mode. And not by fighting your anxiety, but by changing how you relate to it—with compassion, awareness, and choice.
This is where Acceptance and Commitment Therapy (ACT) meets Polyvagal Theory and Somatic (body-based) Practices—a powerful trio for soothing your system and reconnecting with a sense of safety.
Understanding the Fight-or-Flight Response
When we perceive a threat—real or imagined—our body instantly mobilises: heart rate increases, muscles tense, breathing quickens, and our attention narrows. This is the sympathetic nervous system kicking in to prepare us to fight, flee, or freeze.
But here’s the thing: your nervous system can’t always tell the difference between a real danger to life and a stressful email. Or between a traumatic memory and a present-moment experience. So it can react the same way to both—by activating the fight-or-flight response.
Over time, this can become a default setting and your system gets stuck on high alert, making it hard to relax, think clearly, or connect with others.
How ACT Can Help You Step Out of Struggle
In ACT, we don’t try to get rid of anxiety or force the body to calm down. Instead, we practice skills that help us relate to these experiences differently—so they don’t run our lives.
Here’s how ACT helps turn down the dial on the fight-or-flight response:
1. Noticing Without Judging (Present-Moment Awareness)
Rather than fighting your symptoms, we learn to notice them with openness. This is mindfulness in action—noticing the racing heart, shallow breath, or clenched jaw, and simply acknowledging, “Ah, my body’s reacting right now.”
This gentle awareness creates space between you and the reaction, allowing for choice.
2. Defusion from Fearful Thoughts
Anxious thoughts often fuel the fight-or-flight response: “This is too much,” “I can’t handle this,” “Something bad is going to happen.” In ACT, we learn to hold these thoughts lightly—like watching leaves float down a stream—rather than getting tangled in them.
You might say, “I’m noticing my mind is telling me something scary right now,” instead of believing every word.
3. Acceptance of Bodily Sensations
Instead of pushing the discomfort away, ACT invites us to make space for it—to say, “Yes, this is here,” and soften around the experience. This willingness to feel, can help the body return to balance much more quickly, than resistance or struggle ever could.
Bringing the Body Into the Healing Process: Somatic and Polyvagal Practices
While ACT gives us powerful tools for working with the mind, we also need to engage with the body directly. This is where Polyvagal Theory and Somatic Practices come in.
According to Polyvagal Theory (developed by Dr. Stephen Porges), we feel safe not just because of our thoughts—but because of how our nervous system is responding. The vagus nerve plays a key role in shifting us from fight-or-flight (sympathetic) into rest-and-digest (parasympathetic), particularly the ventral vagal state—a state of connection, safety, and calm.
One way would be to:
💨 Extend Your Exhale
Breathing slowly out for longer than you breathe in can gently signal safety to your nervous system. Try 4 seconds in, 6 seconds out. Don’t force the breath—just gently guide it.
A Compassionate Reframe
One of the most important shifts we can make is this:
Your body isn’t broken. It’s doing its best to protect you.
That tight chest, the racing heart, the feeling of being on edge—it’s your nervous system trying to keep you alive. It’s just working overtime in ways that aren’t helpful anymore.
With practice, awareness, and compassion, you can learn to calm your system—not by shutting it down, but by building trust and safety from the inside out.
