Have you ever felt light-headed at the sight of blood, or dizzy when you feel overwhelmed by stress?
Fainting might feel dramatic, or even embarrassing, but it’s actually one of the ways your body tries to keep you safe. You are not weak or broken, your body is doing something incredibly intelligent via your vagus nerve to protect you.
It’s what happens when an animal in the wild faces danger and it can’t escape, it might play dead. Fainting is a biological attempt to protect you, to reduce pain, save energy, or avoid further harm.
Your Body’s Emergency Brake
You’re probably already familiar with your instinctive survival responses of fight, flight or freeze. The vagus nerve is part of the parasympathetic nervous system, or the “rest and digest” branch.
When you feel trapped or overwhelmed, whether that be your boss making high demands on you, or having to constantly push through and override your limits, your nervous system tries to protect you via these instinctive survival responses.
In Polyvagal Theory let’s imagine the vagus as various components in your car – the accelerator pedal, the brake and the handbrake.
Ventral vagal
Imagine this is your brake. You are able to use it slow down when needed, or you can release it to go a bit faster. Ventral vagal is also known as the social engagement system – when you are able to feel safe, at ease and connect socially.
Sympathetic activation
Imagine this is your accelerator pedal as it helps you to take action and get away. Sympathetic activation is also known as your fight or flight response.
Dorsal vagal
Imagine this is your emergency handbrake. It’s when your nervous system goes into a shutdown survival response. This is also known as freezing, collapsing or fainting.
Fainting is the deepest layer of shutdown. When the first two options aren’t possible and your system senses “there’s no way out”, your body triggers a shutdown response. It’s as if your emergency handbrake has been pulled to force you to stop, conserve energy and wait until it’s safe again.
Vasovagal Syncope Explained
Vasovagal syncope is the medical term for fainting. “Vaso” relates to blood vessels; and “vagal” refers to the vagus nerve. Together, they describe a reflex that slows your heart rate down, widens your blood vessels and your blood pressure drops quickly.
As less blood reaches your brain, the lights go out – literally! This a protective reflex, it’s your body saying “This is too much, let’s switch off for a moment.”
Common symptoms before fainting:
- Dizziness
- Nausea
- Blurred vision
- Ringing in the ears
- Feeling hot or clammy
- Weakness or feeling limp
- A sense that “something is about to happen”
- Followed by briefly losing consciousness
Afterwards, you may experience fatigue, confusion, or emotional shakiness. These are all signs that your system is slowly trying to return to a state of balance.
As a trauma survivor if you have had this experience, fainting can feel very scary and out of control. It may be helpful to understand that your nervous system remembers what once helped it to survive, and so it uses that survival response again.
Finding Safety Again
Your body isn’t betraying you; it is trying to protect you. Healing trauma begins when you learn how to speak the language of the body, listen to its signals and respond to it with compassion.
Your vagus nerve isn’t your enemy, it’s your built-in guardian – sometimes overprotective, but always acting from a place of survival. And with neuroeducation, understanding and safety, it can become your greatest ally in healing trauma.
I am trained to help you to gently recalibrate your nervous system to feel safe again.
Through Polyvagal-informed therapy and specific trauma sensitive sequencing, I’ll work with you to build awareness of these patterns without shame, so that your vagus nerve learns new patterns of safety and connection.
If you recognise these patterns in yourself, and you’d like support to feel safe and steady in your body again, I offer 1:1 trauma recovery video consultations. Together, we can help your nervous system to regulate, recalibrate and move from collapse to connection.
