What Is the Window of Tolerance and Why It Matters in Trauma Healing from a Decolonizing Perspective
by Dr. Denise Renye
The concept of the window of tolerance is central to trauma-informed care, somatic therapy, and understanding how our nervous system responds to stress. From a decolonizing perspective, we also recognize that Western psychology often frames trauma, regulation, and emotional responses in ways that may overlook cultural, intergenerational, and systemic factors.
The window of tolerance describes the optimal zone of arousal in which a person can process emotions, respond to challenges, and stay connected to themselves and their community. When viewed through a decolonizing lens, it is important to understand how systemic oppression, colonization, and historical trauma can impact this window.
Understanding the Window of Tolerance
The window of tolerance is a term coined by Dr. Dan Siegel, referring to the range of emotional and physiological arousal in which people function effectively. When within this window, individuals can think clearly, respond to situations appropriately, and regulate emotions.
In communities affected by historical oppression or intergenerational trauma, the window of tolerance may be narrowed by chronic stress, marginalization, or the need for vigilance in unsafe environments.
Being inside the window of tolerance can feel like:
Calm and grounded, even in challenging contexts
Present with self and community
Able to navigate emotions without becoming overwhelmed
Connected to cultural and relational resources
What Happens Outside the Window of Tolerance
When the nervous system moves outside this window, hyperarousal or hypoarousal states occur. Both reflect dysregulation, but in a decolonizing frame, we understand these states as adaptive responses to environmental and systemic stress, not personal weakness.
Hyperarousal may include:
Anxiety, panic, or hypervigilance
Racing thoughts or internalized fear
Anger or irritability in response to oppression
Feeling constantly on edge or unsafe in a sociopolitical context
Hypoarousal may include:
Emotional numbness or disconnection
Fatigue or shutdown in response to chronic stress
Difficulty accessing emotions or expressing needs
Dissociation or withdrawal from unsafe or unwelcoming environments
Both hyperarousal and hypoarousal make navigating relationships, work, and daily life challenging, particularly in communities affected by systemic harm.
Why the Window of Tolerance Matters in Trauma Healing
Trauma, especially intergenerational or systemic trauma, can shrink or destabilize the window of tolerance. People may find themselves frequently outside their window as a survival mechanism in environments shaped by oppression, discrimination, or historical violence.
Understanding the window of tolerance allows us to:
Recognize when the nervous system is dysregulated
Approach self-regulation with compassion, acknowledging cultural and systemic factors
Build resilience and emotional flexibility within the context of lived experience
Improve relationships and community engagement by responding instead of reacting
Distinguish between intuition and anxiety in a culturally aware framework
Expanding and Strengthening Your Window of Tolerance
Therapeutic practices and somatic tools can help expand the window of tolerance over time, with attention to cultural and contextual factors. Effective approaches may include:
Somatic awareness and body-based practices, including breath work, movement, or grounding exercises rooted in culturally relevant practices
Trauma-informed therapy that considers historical and systemic trauma
Mindfulness and meditation practices adapted to cultural and personal contexts
Gradual exposure to tolerable stress while maintaining cultural safety and community support
Tracking triggers and responses to understand patterns in a sociocultural framework
Consistent practice can help the nervous system become more flexible, allowing for emotional regulation, deeper connection, and greater capacity for collective and individual healing.
Recognizing When You Are Inside Your Window of Tolerance
Signs that you are within your window of tolerance may include:
Feeling present and able to think clearly
Emotional flexibility and resilience
Ability to engage with others and maintain boundaries
Capacity to navigate uncertainty without becoming overwhelmed
Feeling connected to cultural, community, and relational resources
Recognizing these moments reinforces self-awareness and supports healing that is both individual and collective.
Honoring your window of tolerance is not only a cornerstone of trauma-informed care and somatic therapy, but also a vital step in decolonizing approaches to mental health. By tracking your states, practicing self-regulation, and considering the influence of historical, systemic, and cultural factors, you can expand your capacity for emotional resilience, healthy relationships, and authentic living.
