Nervous System Test

The invisible lens of your reality

Before you think, before you feel, your nervous system has already decided if you are safe or in danger. This automatic response shapes how you see the world, how you relate to others, and how you react under pressure.

Block A evaluates your current state of regulation, your dominant stress responses, and how quickly your system recovers after an intense event.

Stephen Porges' Polyvagal Theory and Daniel Siegel's window of tolerance model are the scientific frameworks behind this test. Both agree on something essential: there is no single "correct" stress response, only patterns that were adaptive in a past context and that may be causing problems today.

The 4 Stress Responses

What is the Window of Tolerance?

It is the range of activation where you can function optimally: neither too activated (anxiety, rage) nor too deactivated (dissociation, numbness). Understanding where your limits are is the first step to expanding them.

Who is it for?

For anyone who feels overwhelmed by their emotional or physical reactions to stress, who can't "switch off" at the end of the day, who freezes during conflict, or who consistently accommodates others at their own expense. It's especially useful as a first step before any integration or personal development work.

How it shows up in everyday life

These four responses don't wait for a real emergency to switch on. They activate around ordinary triggers that your body reads as threat even when your mind knows better:

• Replying to a tense email with your heart already racing before you've even finished reading the second line.
• Going blank in a meeting the moment someone asks you something direct, even though you know the answer perfectly well.
• Saying yes to something you don't want to do, feeling the knot in your stomach, just to avoid the conflict of saying no.
• Needing to move or step outside after a difficult conversation, unable to fully explain why sitting still feels unbearable.

None of these reactions is a conscious choice: they're the fastest exit your autonomic nervous system can find to discharge activation, long before the rational part of your brain gets a say.
