Why we shut down?
Why we explode?
And how we can feel more in control?
The Window of Tolerance is a concept that helps us understand our emotional and nervous system responses. Think of it as the zone where you feel safe, present, and able to cope with life. When you’re within this window, you can think clearly, manage emotions, and respond rather than react. But stress or trauma can shrink this window, pushing us into one of two states:
1. Hypoarousal (Below the Window): This is the “freeze” or “shut down” response. You may feel numb, disconnected, tired, or empty.
Example: Tanya receives negative feedback at work. She goes quiet, avoids everyone, and feels like she doesn’t exist. She wants to cry but can’t. She’s not lazy, she’s frozen.
2. Optimal Arousal (Within the Window): This is where we thrive. We feel safe, alert, and able to handle what’s happening.
Example: Later, after some deep breathing and a short walk, Tanya reflects on the feedback and plans how to improve, no self-blame, just awareness.
3. Hyperarousal (Above the Window): This is the “fight or flight” state. You may feel overwhelmed, anxious, angry, or out of control.
Example: On another day, the same feedback makes Tanya lash out, defend herself, and feel like she’s being attacked. Her heart races. She storms out of the meeting.
How to Expand Your Window of Tolerance?
1. Name the state you’re in: “I’m shutting down” or “I’m spiraling.”
2. Breathe slowly: Activates the parasympathetic nervous system.
3. Ground yourself: Use your senses: touch something cold, smell something calming, or name 5 things you see.
4. Practice daily regulation: Yoga, mindfulness, therapy, safe relationships.
5. Co-regulate with others: A calm person can help you return to your window.
6. Understand your trauma history: Your past shaped your window. Knowing how helps you widen it.
I used to think I was just too sensitive. Now I know my nervous system is protecting me the best way it knows how. Let’s be gentle with ourselves. Healing doesn’t mean never leaving the window. It means finding our way back more safely and quickly. 💛
