our body’s ladder: polyvagal hierarchy

Ever feel totally frozen when you’re put on the spot—only to think of the perfect response five minutes later? Or find yourself snapping when you're running on fumes and just trying to hold it together? These aren’t character flaws. It’s your nervous system doing exactly what it was designed to do—shift your physiological state to protect you.

According to Polyvagal Theory, developed by Dr. Stephen Porges, we all have a built-in communication system that sorts our internal and external world into categories: “safe” or “not safe.” Based on what cues it picks up, our body shifts into one of three core physiological states. This is called the polyvagal hierarchy—and understanding it is like getting the user manual for your entire human operating system.

Before we ever form a thought, our nervous system is already scanning the world around us, asking: Am I safe? Do I need to protect myself? That unconscious check-in shapes everything that follows—our energy, emotions, focus, ability to connect, and even our ability to speak.

Try to visualize a plant:

Roots → our physiological state (safe, defense, survival)
Leaves → Thoughts, Emotions, Behaviors

When regulation is off at the roots, the outward growth of our leaves gets tangled. We’ll notice it in anxious thoughts, numbed-out feelings, scattered focus, or reactive behavior.

When our roots are stable and well-nourished, our nervous system can grow thoughts, emotions, and behaviors that are flexible, grounded, and connected.

Three Core States

The nervous system has three main pathways organized in a hierarchy based on how safe we feel:

Ventral Vagal: Safety, Connection, Regulation

This is the state our nervous system is in when it feels safe enough. It’s not just “calm”—it’s curious, open, connected, and flexible. From here, we can think clearly, engage socially, recover from stress, and regulate emotions.

Physiology:

• Heart rate is regulated
• Breath is deep and slow
• Digestion works smoothly
• Body feels grounded and at ease
• Energy is directed toward the prefrontal cortex

Thoughts:

• “I can handle this.”
• “I can ask for help.”
• “I’m curious about this.”

Emotions:

• Calm, confident, connected
• Motivated, present, hopeful

Behaviors:

• Able to communicate clearly
• Can transition between tasks
• Handle change without shutdown

Being in a ventral vagal state doesn’t mean life’s stress-free—it just means your system has a stable home base to come back to.

Sympathetic: Mobilization, Action, Protection

This is your “get up and go” system. When something feels threatening, the sympathetic branch kicks in to help you take action—whether that’s handling a challenge, defending yourself, or just keeping up in a busy world.

Physiology:

• Increased heart rate, shallow breathing
• Muscles prepare for action
• Energy is directed away from the prefrontal cortex and toward muscles, heart, and lungs
  

Thoughts:

• “Something’s wrong.”
• “I need to fix this right now.”
• “They’re mad at me / I’m in trouble.”

Emotions:

• Frustration, panic, shame, dread
• Wired-but-tired, easily startled

Behaviors:

• Becomes more reactive or impulsive
• Quick to anger, panic, or overwhelm
• May talk fast, loudly, or interrupt frequently
• Harder to think clearly, problem-solve, or take in new information
• Expressive language may feel blocked or jumbled
• Decisions feel urgent, black-and-white, or driven by emotion

Sympathetic is a natural protective state. It only becomes a problem when it overrides ventral and takes the lead—your body forgets the threat has passed and gets stuck in constant “do something!” mode.

Dorsal Vagal: Shutdown, Withdrawal, Collapse

If your system senses that action isn’t safe or effective, it shifts into dorsal vagal—a shutdown response designed to protect. It’s like the possum reflex: go still, go quiet, conserve energy. It’s primal, and it’s human.

Physiology:

• Slow heart rate and breath
• Low energy or flat affect
• Digestion shuts down
• Energy use slows down to conserve and protect.

Thoughts:

• “It doesn’t matter.”
• “Why bother?”
• “I can’t do this.”

Emotions:

• Numb, hopeless, invisible
• Emotionally flat or absent

Behaviors:

• Zoning out, pulling away
• Sleeping a lot, difficulty getting started
• Minimal interest in connection

Dorsal is often mistaken for laziness, disengagement—or worse, compliance—when it’s actually the body’s last resort for protection.

Every State Has a Role—Even the Ones That Feel Hard 

Here’s the most misunderstood part of polyvagal theory: the goal isn’t to live in a perfectly calm “zen mode” all the time. You actually need all three states. Sympathetic isn’t the enemy. Dorsal isn’t a dysfunction. Each state has a role to play—as long as they’re working together, not taking over. They’re all built to protect us.

In a well-regulated system, it’s ventral vagal that leads the way—offering a sense of safety and connection. From there:

• Sympathetic can show up as energy, drive, focus, playfulness
• Dorsal can support stillness, connection, creativity, deep reflection

Blended states are where the magic happens—they are real, imperfect, and deeply human.

You might feel mobilized connection - ventral + sympathetic

• Energized, passionate, assertive, and grounded all at once.
• It might look like speaking up in a hard conversation, leading a group with confidence, or dancing like nobody’s watching—fully in your body, fully alive.

Or you might feel a quiet presence - ventral + dorsal

• You’re grounded, inward, and connected to something bigger.
• You may feel this in the energy of a slow morning, a deep exhale, or sitting in quiet closeness with someone who doesn’t need you to perform.

Understanding the polyvagal hierarchy gives language to what your body’s been doing all along. Those big feelings, blank thoughts, or unexpected reactions start to make more sense.

Your nervous system isn’t out to sabotage you. It’s trying to protect you.

And once you know that, you can start meeting yourself with more curiosity and less criticism.

Because, regulation isn’t a finish line to reach—it’s a flow you learn to move with.

shine bright, be you
