The Pain Stored in the Body: Understanding Trauma and the Healing Process

Trauma is often thought of as something that happens in the past and is over. However, for many people experiencing post-traumatic stress symptoms, trauma is not just a past event. The brain’s alarm system, the nervous system, and the body may continue to stay on alert even when the danger has long passed. As a result, a person may logically know they are safe, yet still feel the world as threatening, unpredictable, or requiring constant vigilance.

For someone experiencing Post-Traumatic Stress Disorder (PTSD), trauma is not simply an “there and then” experience. One reason for this is that the brain may not have fully encoded the critical information that the danger has passed. The system behaves as if the catastrophe is still ongoing; the body and mind remain on high alert, repeatedly scanning both the environment and inner experience: “Am I in danger?” This is not a lack of willpower or oversensitivity. Rather, it is the survival system of a nervous system that has once been seriously threatened and has learned to keep the alarm system more tightly engaged. In this process, the brain’s alarm center, the amygdala, plays a key role. After trauma, the amygdala may become more sensitive. The system functions like a radar constantly scanning the environment. Because the threshold is lowered, sounds, smells, or facial expressions that would normally be neutral can quickly turn into threat signals. From the outside, these reactions may look exaggerated or inappropriate to the situation. However, from the inside, they are coherent survival responses. Sudden tension in the body, startle reactions, or rapidly rising emotions are natural expressions of the system’s “stay alert” and “survive” signals.

At the same time, the brain’s time-processing system, the hippocampus, may not function properly. Normally, this structure places experiences on a timeline. However, trauma disrupts this process, causing memories to lose their proper place in time. Because of this, some moments may not feel like past memories but rather like they are happening again. Along with remembering, the person may re-experience the fear, helplessness, and bodily sensations of that moment. Some triggers do not merely remind the past—they can transport the person back into it. At that moment, the body re-enters alarm mode and the mind feels under threat again. The intense fear experienced can then continue to bleed into present moments, casting a shadow even over situations where the person is actually safe.

Traditional textbooks and diagnostic frameworks are often insufficient for understanding the complexity of trauma. Van der Kolk criticizes overreliance on textbooks, stating that they “only take you so far” in understanding lived traumatic experience. Through his provocative statement that a therapist’s license is “only a license for bad practice,” he emphasizes the importance of learning directly from trauma survivors and their personal narratives. Beyond diagnostic criteria, trauma is a deeply personal and embodied reality.

During all of this, the prefrontal systems responsible for thinking and meaning-making can also become less active. When the perception of threat is activated, access to systems that carry the knowledge “I am safe right now” becomes more difficult. Even if the person knows they are safe in theory, they may not be able to access that knowledge in the moment, because the emotional alarm system operates much faster than logical evaluation and can take over control entirely. This disconnection between the amygdala, hippocampus, and prefrontal cortex makes the world feel unpredictable and dangerous. The brain then adapts to this new sense of security through strategies such as avoidance, emotional distance from others, or intolerance of uncertainty. In this process, trauma not only affects biological responses but also fundamentally changes how a person perceives the world and their sense of safety. To make sense of a chaotic and overwhelming experience, the mind develops beliefs such as “people are not trustworthy” or “something bad will happen if I’m not careful.” These thoughts are not random; they are attempts to regain control in a world that has felt shattered. However, over time, these beliefs can become structures that narrow perception, restrict movement, and make the world feel like a confined space. Healing, at this point, is not simply about calming down or trying to forget what happened; it is more about allowing the brain to reconnect its fragmented systems and rebuild a safe, balanced, and meaningful whole.

Healing is not about forgetting what happened or completely shutting down the alarm system. Rather, it is the brain’s ability to continue the unfinished processing of trauma over time. The experience gradually moves out of fragmentation and begins to form a more integrated narrative. Memories slowly find their place in the past, and the body no longer reacts to every signal with the same level of urgency. Over time, the prefrontal cortex becomes more easily engaged again, the hippocampus reorganizes time, and the amygdala becomes more calibrated in distinguishing real threats from non-threats. The radar does not shut off completely, but it no longer has to operate at maximum sensitivity all the time. In this way, the person can gradually begin to experience that while danger was real in the past, not every moment in the present carries the same level of threat. If you are struggling with constant alertness after trauma, physical anxiety symptoms, or the impact of past experiences on your present life, psychotherapy can provide a supportive framework to help make sense of these experiences and create space for the nervous system to regain balance.
