The Nervous System & Relationships
When we experience triggers in our relationships, our nervous system often perceives these moments as a threat to our safety and attachment. This activation shifts the body out of its natural state of social engagement and into a survival mode, such as fight, flight, or freeze. For many, these triggers are rooted in past unresolved events or developmental trauma, which can cause the nervous system to react to current conflicts with the same intensity as historical threats.
In a pursuer-withdrawer cycle for example, the "pursuer" often experiences a fight-or-flight response characterized by hyperarousal. This state involves increased breathing, heart palpitations, and an urgent need for connection to self-regulate. When they feel dismissed or unheard, their nervous system may signal a state of "abandonment" or "invisible" fear, leading them to become louder, more critical, or more expressive in an attempt to be seen and receive empathy.
Conversely, the "withdrawer" typically moves into a state of hypoarousal or a "freeze" response when faced with intense conflict. This can manifest as feeling overwhelmed, shut down, or emotionally numb. In this state, the nervous system attempts to protect itself by withdrawing or intellectualizing the situation to create distance from the perceived emotional threat. This creates a loop where one partner's survival strategy directly triggers the other partner's attachment fears.
These state changes often happen fast and automatically, sometimes without early emotional warning signs. During these shifts, individuals may lose sensory awareness and drop "out of their body," focusing on the "then and there" of past trauma rather than the "here and now" of the present relationship. This fragmentation makes it difficult to stay grounded or use healthy communication skills, as the brain's natural healing and reasoning mechanisms are temporarily offline.
To move out of this cycle, it is essential to implement self-regulating and somatic tools that help shift the focus back to safety. Practices such as grounding, mindful observation of the other person's emotions, and using "I statements" can help de-escalate the nervous system. By understanding how these specific triggers affect our physiology, we can begin to pause, regulate, and communicate from a place of resilience rather than defaulting to automatic defensiveness.
