WINDOW OF TOLERANCE

Happy May! I hope we are all enjoying the sun as much as I am. For my blog this month, I wanted to take a closer look at the Window of Tolerance. What it is, how to identify the different states of our nervous system, and ultimately, how to widen your window. 

What is the Window of Tolerance?

The Window of Tolerance, a term developed by Dr. Dan Siegel, describes the zone in which our nervous system can handle stress without becoming overwhelmed. I often refer to this window as the “green zone” or “flexible zone,” where we can continue our daily life without feeling dysregulated and navigate day-to-day stressors with greater ease. Many find that when they are in their window, they are better able to:

• Stay emotionally regulated and grounded
  
  

• Think clearly and respond intentionally
  
  

• Feel emotions without being consumed by them
  
  

• Connect in relationships with presence and trust
  
  
  

For those who’ve experienced trauma, this window can become very narrow. Even minor stressors may feel like too much, leading to emotional overwhelm—or, on the other end of the spectrum, emotional numbness.

Outside the Window: Trauma Responses

When life pushes us outside of our window of tolerance, we tend to move into fight, flight, or freeze survival responses:

Hyperarousal (Fight or Flight)

This can include:

• Anxiety or panic
  
  

• Anger or irritability
  
  

• Racing thoughts
  
  

• Feeling constantly on edge or unsafe
  
  
  

Hypoarousal (Freeze or Shutdown)

This may show up as:

• Emotional numbness
  
  

• Brain fog or dissociation
  
  

• Feeling stuck, helpless, or disconnected
  
  

• Low motivation or fatigue
  
  
  

These trauma responses are often rooted in early experiences where the nervous system learned that safety and connection were unpredictable. Understanding this is an important part of healing for trauma survivors who have been carrying these responses for years. 

How to Expand Your Window of Tolerance

To come out of hyperarousal, your system needs signals of safety and grounding. You’re helping your body slow down enough to return to that tolerable, regulated zone.

• Breath work (especially long exhales) helps shift you out of a fight/flight state.
  
  

• Movement can help release pent-up energy (e.g., walking, shaking out limbs, dancing).
  
  

• Orienting: Look around the room slowly and name what you see. This signals safety to your brain.
  
  

• Self-talk: Remind yourself, “I’m safe right now,” or “I don’t need to fix everything at once.”
  
  
  

To come out of hypoarousal, your system needs gentle activation — signals that it’s safe to re-engage without becoming overwhelmed.

• Small movements (wiggling fingers/toes, stretching) help reconnect with the body.
  
  

• Temperature shifts (holding a warm mug, splashing cool water) can gently stimulate the system.
  
  

• Rhythmic sensory input, like music, rocking, or tapping, can nudge you into presence.
  
  

• Connection: Texting a friend or hearing a kind voice can reawaken a sense of aliveness.
  
  
  

Expanding your window is about building capacity, not forcing yourself to “handle more.”

You do this through:

• Resourcing: Regularly connecting to sensations, memories, or images that feel safe, warm, or empowering.
  
  

• Titration: Touching on difficult experiences in small doses, then returning to regulation. This builds tolerance without retraumatization.
  
  

• Practice: The more often you intentionally move back into your window, the easier it becomes for your nervous system to return on its own.
  
  
  

It is important to remember that both hyper- and hypoarousal are protective states. Your nervous system isn’t broken — it’s trying to keep you safe based on past experiences. Expanding your window of tolerance is not about getting rid of these responses, but about creating more room to feel, connect, and respond with flexibility.

How can Trauma Therapy Help?

One of the core goals in trauma therapy is to expand your window of tolerance—helping you stay present with more emotion, sensation, and connection without becoming overwhelmed or shutting down.

Depending on your needs, I may integrate:

• EMDR therapy (Eye Movement Desensitization and Reprocessing), a research-backed method for processing stuck traumatic memories
  
  

• Nervous system regulation techniques, including grounding, breathing, and somatic awareness
  
  

• Attachment-based support, especially for those healing from emotionally unsafe or invalidating relationships
  
  

• Mindfulness and psychoeducation to help you understand and care for your nervous system in daily life
  
  

Why This Matters

If you find yourself bouncing between anxiety and numbness, it’s not because you’re “too sensitive” or “broken.” It’s because your body has learned to survive in a world that hasn’t always felt safe. Therapy can help you expand your window of tolerance, allowing you to navigate life with greater steadiness, presence, and choice.
