A Deeper Look Into Trauma
Trauma is a word that is often used in everyday conversation, but what does it actually mean? At its core, trauma refers to a devastating experience that exceeds a person’s ability to cope. This could be either a single event, such as an accident or loss, or a series of ongoing experiences like neglect, abuse, or adverse childhood experiences. What makes something traumatic is not just the event itself, but how it is experienced internally. Two people can go through the same situation, and one person may feel shaken but recover quickly, while the other person may carry lasting emotional and physical effects. This demonstrates that trauma is deeply personal and rooted in how the brain and body respond to perceived threat.
To understand trauma more fully, it helps to explore what it means to be triggered. A trigger is anything that reminds the brain and body of a past traumatic experience. This reminder does not have to be obvious or logical. It could be a sound, a smell, a place, or even a feeling. When a person is triggered, their brain reacts as if the original danger is happening again in the present moment. This reaction is often automatic and outside of conscious control. Physical manifestations can show up in the body such as feeling tense, increased heart rate, faster breathing and emotions such as fear, anger, or sadness can come up suddenly.
Identifying and understanding triggers are an important step in healing from trauma. Triggers are often subtle and can take time to recognise. For example, someone who experienced criticism growing up may feel intense anxiety when receiving feedback at work, even if the feedback is constructive. Another example is a person who was involved in a car accident might feel triggered by driving again, experiencing fear and an overwhelming feeling that something bad is going to happen again. By paying attention to such patterns when strong emotional reactions occur, what happened just before, and how the body responds, this can help you figure out where these triggers are stemming from. Understanding that these reactions are linked to past experiences, rather than present danger, it allows us to separate and create space for greater self-awareness and self-compassion.
A helpful way to understand trauma responses is by looking at the brain in two parts: the ‘front brain’ and the ‘back brain’. While this is a simplified model, it is useful for explaining how we think and react. The front brain including the pre-frontal cortex is more advanced and is responsible for reasoning, decision-making, problem-solving, and emotional regulation. It allows us to reflect, plan, and respond thoughtfully. The back brain, on the other hand, is more primitive and more instinctive. It is responsible for survival and is constantly scanning the environment for threats (this is done subconsciously). It reacts quickly and automatically to keep us safe. Other functions of the back brain include keeping our heart rate going, keeping us breathing, things we don’t think about which shows the role of the back brain is to keep us alive.
Within the back brain is the amygdala which is often described as the brain’s smoke alarm system. This system is designed to detect danger and activate a trauma response when necessary. When functioning well, it helps protect us from real threats. However, for those who have experienced trauma, this system can become over activated. It may go off even when there is no actual danger, much like a smoke alarm that sounds when someone is simply cooking rather than the presence of an actual fire. This is why triggers can feel so intense; the brain is trying to protect, even if the threat is no longer present.
When a person is triggered, there is often a significant shift in which part of the brain is in control. The front brain essentially goes offline, while the back brain takes over. This means that the ability to think clearly, reason, and stay grounded in the present moment is reduced. Instead, the body moves into survival mode. This is why I have heard people say later, ‘I know I completely lost my shit, but it happened so quickly.’ In that moment, the thinking part of the brain was not fully accessible.
A key emotion tied to trauma is the feeling of helplessness. During a traumatic event, a person often feels trapped, powerless, or unable to escape. This sense of helplessness can become stored in the body and mind, resurfacing when triggers occur. Even if the current situation is safe, the body can react as though there is no control or way out. This can be deeply distressing and confusing, especially when you know intellectually that you are not in danger. The messages being received by the brain is ‘we are still in danger’ and so the body can feel stuck with these messages and inability to move out of the stress responses.
The trauma response itself is commonly understood through three main reactions: fight, flight and freeze. The first response is usually flight; the brain quickly decides the best chance of survival is to get away. Some symptoms you can experience physically include heightened alertness and faster breathing. The second trauma response is fight; the brain perceives that you can overpower or handle the threat. Some symptoms you can experience physically include surge in adrenaline, muscle tension and readiness for action or conflict. The freeze response happens when both fighting or escaping feels possible. You can be left feeling numb, disconnected and unable to act, essentially freezing on the spot feeling unable to move. These responses are not choices; they are automatic survival mechanisms. Each one serves a purpose in protecting you, even if it does not feel helpful in the present. Understanding your trauma response can be useful in recognising patterns and helping you understand what is happening in the moment.
Another common trauma response is avoidance. It involves keeping clear of anything that might trigger painful memories or emotions. While avoidance can provide short-term relief, it often reinforces the fear over time. By avoiding triggers, the brain never has the opportunity to learn that the present situation is safe. This can lead to a shrinking world, where more and more situations feel threatening. Understanding avoidance as a protective strategy, rather than a weakness, is an important step towards addressing it with compassion. Through therapy we can learn ways to regulate your nervous system such as grounding techniques.
To make sense of these reactions, some people find it helpful to use the concept of the ‘trauma traffic light.’ This model breaks down emotional states into three zones: green, yellow, and red. The green zone represents a state of calm and safety, where the front brain is engaged and a person feels balanced. The yellow zone is a state of heightened alertness, where stress and anxiety begin to rise. In this zone, triggers may start to activate, but there is still some ability to self-regulate. The red zone represents full activation of the trauma response, where the back brain has taken over and the individual may feel overwhelmed, reactive, or shut down.
Closely related to this is the idea of the ‘window of tolerance.’ This refers to the range of emotional intensity that a person can handle while still remaining grounded and regulated. When you are within the window of tolerance you can think clearly, process emotions, and respond effectively. Trauma can narrow this window, making it easier to become overwhelmed (moving into the red zone) or shut down (dropping below the window into numbness). Expanding the window of tolerance is a key goal in trauma healing, as it allows for greater resilience and flexibility when dealing with overwhelming feelings.
So how can you begin to work with triggers and trauma responses? One important strategy is grounding. Grounding techniques help bring attention back to the present moment and re-engage the front brain. This might include focusing on the breathing (such as box breathing exercises), noticing physical sensations, or naming things in the environment (5-4-3-2-1 exercise). Simple actions like placing feet firmly on the ground or holding onto a solid object can signal safety to the body.
Another helpful approach is building awareness. This involves recognising early signs of being triggered such as muscle tension, changes in breathing, or racing thoughts before the response escalates and the back brain takes over. By catching these signals early, you may be able to intervene before reaching the red zone. Over time, this awareness can create a sense of being in control again and reduce the intensity of reactions.
Developing self-compassion is also essential. Trauma responses are not signs of weakness or failure; they are the body’s way of trying to protect you from perceived threats and harm. Instead of judging these reactions, it can be more helpful to approach them with curiosity and kindness. Asking questions like ‘What is my body trying to tell me?’ or ‘What do I need right now?’ can shift the experience from one of shame and judgement to one of understanding.
Connection with others plays a powerful role in the healing journey. Trauma can create a sense of isolation, but supportive relationships can help restore a sense of safety. Being seen, heard, and understood by others can counteract the helplessness that trauma often brings. Even small moments of connection can have a meaningful impact on the nervous system.
Finally, the concept of integration is central to trauma healing. Integration involves bringing together the different parts of the experience (the thoughts, emotions, and physical sensations) so that they can be processed and understood as part of the past, rather than something that is still happening. When trauma is unprocessed, it remains fragmented, which is why triggers can feel so immediate and intense. Through integration, these experiences become more manageable and less overwhelming.
Integration does not mean forgetting or erasing what happened. Instead, it means being able to remember the experience without being overtaken by it. The memory becomes something that is held, rather than something that controls you. This process takes time and often requires support in a therapeutic environment, but it is a powerful step toward reclaiming a sense of safety and stability.
In conclusion, trauma is a complex and a deeply human experience that affects both the brain and body. Understanding concepts like triggers, the front and back brain, the smoke alarm system, and trauma responses can provide valuable insight into why we react the way we do. By recognising patterns, building awareness, and developing supportive strategies, it is possible to move towards healing. While the effects of trauma can be painful, giving ourselves the capacity for growth, resilience, and integration is transformational. Healing is not about eliminating all triggers or never feeling overwhelmed again, it is about learning how to navigate these experiences with greater understanding, compassion, and control.
