Key facts
What is the How to Regulate Your Nervous System?
Nervous system regulation refers to the capacity to notice arousal states and return to an optimal zone. The window of tolerance and polyvagal-informed frameworks describe hyperarousal, optimal arousal and hypoarousal.
Why it works
Siegel (1999) introduced the window of tolerance concept. Polyvagal theory offers a framework for understanding states of safety, mobilization and shutdown (Porges, 2011), though some physiological claims are debated.
When to use it
- Trauma-informed therapy
- Anxiety and panic
- Dissociation and shutdown
- Somatic approaches
How to use it in session
- Explain the three states.
- Identify personal signs.
- Choose strategies for each state.
- Practise in session.
- Track states between sessions.
Clinician tips
- Frame all states as protective.
- Match strategies to state (up-regulate vs down-regulate).
- Pair with the window of tolerance tracker.
