We all move up and down this ladder throughout the day. It is completely normal. Open a state to explore it.
💚 Ventral Vagal Pathway
Safety, Connection, Regulation
The inner voice: “I am safe. I can connect. I can thrive.”
What happens in the body:
- Face & Eyes: Facial muscles soften, eyes brighten, pupils relax
- Middle Ear: Tunes to human voice frequencies, filters out danger sounds
- Vocal Cords: Voice becomes melodic and expressive (prosody)
- Heart: 'Vagal brake' slows heart rate, keeping it steady and calm
- Lungs: Breathing is slow, deep, and steady
The myelinated vagus nerve acts as a 'brake' on the heart and lungs, keeping your body in a calm, regulated state. Several cranial nerves, including the vagus, are involved in your face, voice, and hearing, which is why you can often tell a lot about how someone feels from their face or voice.
Typical feelings: Safe, Connected, Calm, Curious, Open, Engaged.
🧡 Sympathetic Nervous System
Mobilization, Fight, Flight
The inner voice: “There is danger. I need to act.”
What happens in the body:
- Heart: Pumps faster to deliver blood and oxygen to muscles
- Lungs: Airways open wide to increase oxygen intake
- Muscles: Activate and tense, preparing for rapid movement
- Adrenal Glands: Release adrenaline and cortisol to fuel protective action
- Digestion: Shuts down. Energy is redirected away from the gut
Your body mobilizes for survival. Heart rate increases, breathing quickens, muscles tense, and stress hormones flood your system. Blood flow shifts away from digestion and toward your limbs. This is your body's way of preparing you to fight the threat or run from it.
Typical feelings: Alert, Anxious, Irritable, Restless, Overwhelmed, On Edge.
🩶 Dorsal Vagal Pathway
Immobilization, Collapse, Numbness
The inner voice: “I can't cope. I need to shut down.”
What happens in the body:
- Heart: Slows dramatically, blood pressure drops
- Lungs: Breathing becomes shallow and slow
- Stomach & Intestines: May slow down or become unsettled (for example, nausea)
- Liver: Metabolic processes slow to conserve energy
- Whole Body: Metabolism drops, pain signaling may reduce, numbness sets in
When the nervous system determines that fighting or fleeing is impossible, it drops into the most ancient survival mode. Heart rate and blood pressure plummet, metabolism slows drastically, and you may feel numb, disconnected, or frozen. This conserves energy and reduces pain, your body's last-resort protection.
Typical feelings: Numb, Tired, Shut Down, Hopeless, Disconnected, Frozen.
Three organizing principles
- Co-Regulation: We are wired for connection. Our nervous systems regulate through safe, supportive relationships. A calm presence from another person can help shift our own nervous system toward safety.
- Neuroception: Our nervous system constantly scans the environment for cues of safety, danger, or life threat, without us consciously thinking about it. This automatic detection system operates below awareness.
- Hierarchy: When our nervous system detects threat, it moves through a predictable sequence of responses, from social engagement, to fight/flight, to shutdown, always trying to keep us safe.
How we move up the ladder
These tools help your nervous system shift back toward safety and connection.
- Safe Relationships: Connection and support from trusted people
- Regulation Skills: Breathing, grounding, and self-soothing techniques
- Body & Breath Awareness: Noticing signals early before overwhelm sets in
- Gentle Movement: Stretching, walking, yoga, or any calming movement
- Environment & Routine: Predictability, comfort, and a sense of safety in your space
When it becomes difficult
The challenge comes when past traumatic experiences leave an imprint on your nervous system. When something in the present, a sound, a smell, a tone of voice, even a body posture, reminds your system of a past threat, your body can react as if the danger is happening right now.
Your heart races. Your muscles tense. You may feel the same fear, the same helplessness, the same overwhelming need to escape or shut down, even when you are objectively safe. This isn’t a choice. It isn’t weakness. It is your nervous system doing what it learned to do to protect you.
Trauma doesn’t mean something is wrong with you. It means your nervous system may have gotten stuck in a protective state. Therapy can help your nervous system learn that the danger has passed. Through safe relationships, body awareness, breathing, and gentle movement, you can gradually build the flexibility to move up the ladder more easily, and to recover more quickly when you drop down.
The goal is not to stay in one state forever. It is to build flexibility: the ability to move between states with awareness and to return to safety, connection, and regulation.
Why it matters
- Make sense of your reactions: Understanding your biology reduces shame and self-blame
- Respond with compassion: Replace judgment with understanding, for yourself and others
- Build resilience and flexibility: Expand your Window of Tolerance so you bounce back faster
- Support others through co-regulation: Your calm presence can help someone else's nervous system settle
