Window of Tolerance
Window of Tolerance (WOT): A Simple Explanation
Adapted from Dan Siegel’s Window of Tolerance model, the Window of Tolerance is the range of arousal in which a person can think clearly, feel their feelings without being overwhelmed, and stay connected to themselves and others. Inside this window, the nervous system feels safe enough.
Adapted from Dan Siegel’s Window of Tolerance model, the Window of Tolerance is the range of arousal in which a person can think clearly, feel their feelings without being overwhelmed, and stay connected to themselves and others. Inside this window, the nervous system feels safe enough.
When we’re inside the window, we can:
What Happens Outside the Window
We move outside the window when our nervous system perceives danger—real or imagined.
1. Hyperarousal (Too Much Activation – “Fight/Flight”)
Nervous system speeds up.
Common signs:
“Everything is too much.”
“I need this to stop right now.”
2. Hypoarousal (Too Little Activation – “Freeze/Shutdown”)
Nervous system crashes or goes offline.
Common signs:
“I can’t feel anything.”
“I’m gone.”
“I don’t know.”
Why This Matters for Couples or Families
When partners or family members go outside their window:
What Expands the Window of Tolerance?
- Notice feelings without getting swept away
- Communicate and problem-solve
- Stay flexible and grounded
- Access curiosity, empathy, and connection
What Happens Outside the Window
We move outside the window when our nervous system perceives danger—real or imagined.
1. Hyperarousal (Too Much Activation – “Fight/Flight”)
Nervous system speeds up.
Common signs:
- Anger, irritation, panic
- Racing thoughts or racing heart
- Urges to argue, defend, escape, fix, or shut down conversation
- Feeling overwhelmed or out of control
“Everything is too much.”
“I need this to stop right now.”
2. Hypoarousal (Too Little Activation – “Freeze/Shutdown”)
Nervous system crashes or goes offline.
Common signs:
- Numbing, zoning out, dissociation
- Collapse, exhaustion, going quiet
- Feeling disconnected, foggy, or blank
- Difficulty speaking or accessing words
“I can’t feel anything.”
“I’m gone.”
“I don’t know.”
Why This Matters for Couples or Families
When partners or family members go outside their window:
- Curiosity disappears
- Misinterpretations skyrocket
- “Proving the facts” or “getting it right” replaces connection
- Protest behaviors (pursuing, criticizing, withdrawing, shutting down) take over
- Repair becomes nearly impossible until the system is regulated again
What Expands the Window of Tolerance?
- Co-regulation (warm tone, soft eyes, grounding touch if appropriate)
- Interoceptive awareness (noticing body cues early—tension, breath, heart rate)
- Emotional differentiation (naming what you feel before it escalates)
- Predictability and structure in conversations (agreements, time-outs, scripts)
- Trauma-informed therapy (IFS, EMDR, Brainspotting, KAP, mindfulness)
- Nervous-system practices (breathwork, orienting, paced breathing, grounding)
