If you’ve ever snapped at someone you love during an argument, found yourself frozen mid-conversation and unable to speak, left a party earlier than you planned, or said yes to something you really didn’t want to do — your nervous system was doing exactly what it was designed to do. It was trying to protect you.

Before we talk about managing anxiety, it helps to understand what anxiety actually is at its root: a survival response. The human nervous system is wired for protection. Long before we were navigating difficult conversations and social expectations, our ancestors needed fast, automatic responses to physical danger. That wiring hasn’t changed. What’s changed is the world we’re applying it to. Understanding your own nervous system’s particular flavour of protection is one of the most compassionate and empowering things you can do for yourself.

The Four Protection Responses

When your nervous system perceives a threat — whether that’s a predator, a confrontational boss, a crowded grocery store, or an unread text from someone you care about — it activates one of four protective responses. Here’s what each one looks and feels like.

Fight

The fight response mobilizes you to confront the perceived threat head-on. Your body floods with energy and your instinct is to push back, defend, or assert control.

Common signs: anger, irritability, the urge to control situations or people, physical tension, raised voice
Example: you feel threatened during a disagreement and raise your voice to defend yourself, even when part of you knows the situation doesn’t call for it

Flight

The flight response urges you to escape, avoid, or get away from what feels dangerous. It’s the part of you that would rather not be in the room at all.

Common signs: restlessness, panic, excessive worrying, avoiding people, places, or situations that feel uncomfortable
Example: you leave a crowded room because the overwhelm becomes unbearable, or you cancel plans to avoid the anxiety of showing up

Freeze

The freeze response immobilizes you. When neither fighting nor fleeing feels like an option, the nervous system can shut down, leaving you stuck, zoned out, or disconnected.

Common signs: zoning out, dissociation, difficulty making decisions, emotional numbness, feeling “not really there”
Example: during a stressful event, you mentally check out and feel disconnected from your body or your surroundings, even though you’re physically present

Fawn

The fawn response is perhaps the least talked about, and the most misunderstood. Rather than fighting, fleeing, or freezing, the fawn response moves you toward the threat, attempting to appease it in order to stay safe.

Common signs: people-pleasing, difficulty saying no, neglecting your own needs, over-apologizing, feeling responsible for other people’s emotions
Example: you agree to something you genuinely don’t want to do because you fear rejection, criticism, or having to navigate the other person’s emotional reaction

Anxiety Isn’t the Enemy

Here’s something worth sitting with: anxiety isn’t the problem. It’s a protector that has been working overtime.

It makes sense that your body learned to stay on alert. At some point, that alertness kept you safe. Your nervous system is not broken — it’s loyal. It has been doing exactly what it learned to do. The difficulty is that the strategies it developed — the avoidance, the people-pleasing, the shutting down — were built for a different time and a different version of the threat. And sometimes, when we keep doing things to manage our anxiety (like avoiding the things that trigger it), we actually reinforce it. Every time we avoid something, we send a quiet message to the brain: that thing is dangerous. And the anxiety grows a little stronger.

Rather than trying to fight, silence, or override the anxious part of you, what if you got curious about it? Here are some questions worth sitting with:

If the anxious part of you could talk, what do you think it would say? What does it want you to know?
Where do you feel it show up in your body? Does it have a sensation, a quality, a colour, a shape?
What do you think it believes it’s working so hard to protect you from?
What would it be like to meet the anxious part with curiosity, instead of fear, frustration, or judgment?

Helpful Regulation Tools

When your nervous system is activated, trying to “think your way out” of it rarely works — because the response is happening below the level of rational thought. What does work is sending safety signals directly to the body. Here are three tools grounded in nervous system science that can help.

Box Breathing

Box breathing is a simple but powerful technique that activates the parasympathetic nervous system (your “rest and digest” state) by slowing and regulating the breath.

Inhale through your nose for 4 slow seconds, noticing how the air feels as it fills your lungs
Softly hold the breath for 4 seconds, sitting in the stillness
Slowly exhale through your mouth (shape your lips like a straw) for 4 seconds, noticing how your lungs and body soften as the air leaves
Softly hold at the end of the exhale for another 4 seconds, sitting in the stillness again
Repeat as many times as you need

Physiological Sigh

Research out of Stanford has found that the physiological sigh is one of the fastest ways to reduce physiological stress in real time. It works by fully deflating the air sacs in the lungs and resetting the respiratory system.

Take a deep inhale through your nose
At the top of that breath, add one more sharp inhale to fully fill the lungs
Exhale slowly and completely through your mouth until all the air is out
Repeat a few times until you notice a shift

Pendulation

Pendulation is a somatic (body-based) technique that helps the nervous system move between activation and calm, gradually expanding your window of tolerance for difficult sensations.

Notice where activation is showing up in your body (chest, shoulders, stomach, neck, jaw)
Label the sensation (tension, tightness, pressure, heaviness, fluttering, nausea)
Welcome the feeling in and try to sit with it with curiosity rather than resistance
Then gently shift your attention to a different part of your body that feels more calm, relaxed, or neutral (even if it’s just the tip of your nose or your pinky toe)
Label that sensation too (softness, warmth, lightness, stillness)
Slowly move your attention back and forth between the two places, allowing your nervous system to soften and find more regulation

These tools won’t eliminate anxiety, and they’re not meant to. The goal is to help your nervous system find enough safety to come back online, so you can respond to your life rather than react to it.

If you find yourself identifying strongly with one or more of these responses, or if anxiety is significantly affecting your daily life and relationships, therapy can be a powerful space to explore where these patterns came from and how to gently, sustainably shift them. You don’t have to figure this out alone.
