Have you ever walked into a room and suddenly felt your heart race for no apparent reason? Or caught a certain scent that made your stomach clench with unexplained dread? These reactions aren't random. They're your body speaking a language your conscious mind may have forgotten. Research has consistently shown that trauma is stored in somatic memory and expressed as changes in the biological stress response.
When we experience overwhelming events, something profound happens beneath our conscious awareness. While your mind may push traumatic memories aside, your body becomes a vigilant keeper of these experiences. This isn't weakness or overreaction,it's a biological reality rooted in how your nervous system processes and stores threatening experiences.
Your Body's Secret Filing System
Think of your body as having two different filing systems for memories. The first is like a well organized office where your conscious mind stores events you can easily access and describe. The second is more like an ancient alarm system that files experiences as bodily sensations, muscle tension, and physiological responses. In PTSD, failure of declarative memory may lead to organization of the trauma on a somatosensory level as visual images or physical sensations that are relatively impervious to change.
Dr. Bessel van der Kolk, whose research at Harvard Medical School pioneered our understanding of trauma and the body, discovered that trauma creates changes in the brain's wiring, leading to difficulties in identifying and talking about experiences. This means your body may remember what your mind struggles to put into words.
Your Nervous System Never Forgets
Intense emotions at the time of trauma initiate long-term conditional responses to reminders of the event, which are associated with chronic alterations in the physiological stress response. This means your nervous system continues responding to triggers as if the original threat is still present, even years later.
The Science Behind Body Memory
Your autonomic nervous system operates like a sophisticated security system that never takes a break. According to polyvagal theory, developed by Dr. Stephen Porges, the autonomic nervous system supports social engagement, emotional resilience, and adaptive physiological responses through a hierarchical organization mediated by the vagus nerve.
This system constantly scans your environment through a process called neuroception,your nervous system's ability to detect safety or danger without conscious thought. When we experience trauma, our neuroception can become distorted or biased toward detecting danger, influencing us to believe that safe situations are unsafe.
The implications run deeper than you might imagine. Animal research suggests that intense emotional memories are processed outside of the hippocampally mediated memory system and are difficult to extinguish. This means traumatic memories bypass your normal memory processing and get stored in more primitive brain regions that prioritize survival over understanding.
When Your Body Keeps Score
SAMHSA, the federal agency overseeing mental health services, recognizes that trauma can have a negative effect on a person's functioning and mental, physical, social, emotional, or spiritual well-being. This comprehensive impact occurs because your body doesn't distinguish between past and present threats when it comes to survival.
When humans feel safe, their nervous systems support the homeostatic functions of health, growth, and restoration, while they simultaneously become accessible to others without feeling or expressing threat and vulnerability
But when your nervous system remains locked in defensive mode, trauma induces persistent changes in the nervous system, often resulting in chronic autonomic dysregulation. This dysregulation manifests in countless ways: chronic pain, digestive issues, sleep disturbances, autoimmune conditions, and heightened startle responses.
The Hidden Language of Trauma Responses
Your body speaks through symptoms that may seem unrelated to past experiences. Maybe you find yourself holding your breath in certain situations. Perhaps your shoulders carry tension that no amount of massage can release. These aren't character flaws,they're adaptations your nervous system created to help you survive.
Understanding polyvagal theory helps explain these responses. According to Polyvagal Theory, we rely on the newest responses to help us return to a state of safety. But when the newer responses fail, we regress to using older evolutionary responses. Your body moves through a hierarchy: social engagement, fight or flight, and finally freeze or collapse.
Research shows that trauma affects you on a cellular level. This cellular impact helps explain why traditional talk therapy alone sometimes falls short. When trauma lives in your tissues, healing must address both mind and body.
The Path Forward
Recognition is the first step toward healing. Polyvagal Theory helps us understand how our body and brain work together to respond to stressors that are a part of everyday life as well as experiences that are more significant, such as trauma. This understanding opens doors to body based healing approaches.
SAMHSA emphasizes that effective trauma treatment requires recognizing how trauma affects all individuals involved with the program, organization, or system. This recognition extends to understanding that your body's responses aren't pathology,they're information.
The journey toward healing involves learning to listen to your body's wisdom while gently teaching your nervous system that the danger has passed. This process takes time, patience, and often professional support from practitioners who understand trauma's embodied nature.
Your body has been keeping score, but it's also been keeping you alive. Now it's time to help it learn that you're safe to heal.
