You Remember What Happened but Why Does Your Body Still React? Is It a Trauma Response?
Have you ever experienced something upsetting or frightening in the past and thought:
“I know I'm safe now. I know it happened years ago. So why does my body still react as though it's happening again?”
Perhaps your heart starts racing when something reminds you of what happened. You feel sick, shaky or suddenly overwhelmed. You might find yourself wanting to escape, becoming very alert to what is happening around you, or feeling completely numb and disconnected. Sometimes the reaction seems far bigger than the situation in front of you. You may even tell yourself:
“I'm being ridiculous.”
“I should be over this by now.”
“It happened a long time ago.”
But trauma isn't simply about remembering what happened.
Sometimes the body has learned to respond to danger even when the danger is no longer there.
Understanding this can be an important first step towards recovery.
What is a trauma response?
When we experience something frightening, threatening or overwhelming, our nervous system responds to help protect us. We might fight, run away, freeze, become extremely alert or try to find a way of staying safe. This is a normal human response to danger. The difficulty can arise when the experience has ended but the nervous system continues to respond as though danger might still be present. A reminder doesn't necessarily have to be obvious.
It could be:
a particular smell
a sound
a place
someone's tone of voice
a certain type of relationship
a physical sensation
a photograph
a date or anniversary
a particular thought or feeling
You may consciously know that you are safe, while another part of your nervous system reacts differently. This can be confusing and frightening.
Why can the body react when I know I'm safe?
Our brains are constantly taking in information and looking for potential danger. After a traumatic or overwhelming experience, the brain can become particularly sensitive to anything that resembles the original threat. This is sometimes described as the nervous system becoming “stuck on alert.” Someone, for example, who experienced a frightening event involving a particular sound may find that sound triggering years later. They don't necessarily consciously think:
“This sound means the traumatic event is happening again.”
Instead, their body may react first.
Their heart races.
Their muscles tense.
Their breathing changes.
They feel an urge to get away.
The response can happen before they have had time to think about what is happening. This is one reason simply telling yourself “I'm safe” doesn't always make the reaction disappear. The thinking part of the brain may know you are safe, while the nervous system is responding as though it needs to protect you.
Trauma can live in the body
People sometimes expect trauma to look like vivid memories or nightmares. For some people it does. For others, trauma may show up more subtly through physical and emotional responses. You might experience:
racing heart
tightness in your chest
nausea
sweating
trembling
feeling on edge
difficulty sleeping
irritability or anger
feeling detached or numb
panic
difficulty concentrating
avoiding particular situations
feeling unsafe even when there is no obvious danger
You may not always understand why these things are happening. This can lead to another layer of distress:
“Why am I reacting like this?”
That question can sometimes become more painful than the original reaction.
Why do I avoid things that remind me of what happened?
Avoidance is a very understandable response to fear. If something makes us feel unsafe, our natural instinct may be to stay away from it. Initially, this can work. You avoid the situation and your anxiety decreases. Your body relaxes.
You feel safer but your brain may then learn:
“Avoiding this kept me safe.”
The next time you encounter something similar, the urge to avoid may become stronger. Over time, your world can become smaller. You might stop going to certain places, avoid particular people, change your routines or constantly monitor your surroundings. You may know that the avoidance is affecting your life, but still feel unable to stop. Again, this doesn't mean that you are weak. It means your protective system is trying very hard to keep you safe.
Why can reactions seem to come from nowhere?
Sometimes a trauma response has an obvious trigger. Other times it seems to appear completely unexpectedly.
You might suddenly feel anxious or distressed without immediately knowing why. There may be a connection that your conscious mind hasn't identified. A smell, sound, physical sensation, facial expression or situation may have reminded your brain of something from the past. This doesn't mean that every uncomfortable feeling is caused by trauma. When a response seems disproportionate, persistent or difficult to understand, it can be useful to become curious rather than critical. Instead of:
“What's wrong with me?”
you might ask:
“What might my body be responding to?”
Does this mean I haven't healed?
Not necessarily. Recovery from trauma isn't always a straightforward process. You may have gone for years feeling that you had moved on, only to find that something has brought old feelings back. Sometimes a new life experience can activate something from the past. Becoming a parent, for example, entering a new relationship, experiencing a loss or going through a significant change can sometimes bring old experiences into awareness. This doesn't mean you have failed. It may simply mean that something that was previously manageable now needs attention.
How can therapy help?
One of the aims of trauma therapy is not simply to make you talk repeatedly about what happened. It is to help you develop a different relationship with the memories, feelings and physical responses associated with the experience.
In counselling, we can explore what happens when you are triggered, what you notice in your body, what thoughts and beliefs arise, and how you have learned to protect yourself. An integrative approach can be particularly helpful because there isn't always one explanation for why someone continues to struggle after a difficult experience. We can consider thoughts and behaviours, emotions, relationships, attachment experiences and the ways in which earlier experiences may still influence the present. The aim is to understand the whole person rather than simply focusing on a symptom.
Where does EMDR fit in?
EMDR (Eye Movement Desensitisation and Reprocessing) is a therapy that can be used to help people process distressing or traumatic experiences. It is based on the idea that some experiences may not have been fully processed and can continue to feel emotionally or physically present. During EMDR, the therapist helps you access aspects of the experience while using bilateral stimulation, such as guided eye movements or another form of alternating stimulation. The aim is not to erase the memory.
You will still remember what happened, but the memory may no longer feel as though it is happening to you now.
For some people, this can mean that previously intense physical reactions become less powerful. A situation that once triggered panic may become more manageable. A memory that once felt overwhelming may become something you can remember without being completely pulled back into the experience. EMDR is not suitable for everyone at every point in their therapy, and a careful assessment is important before beginning trauma processing.
You are not your trauma response
Perhaps one of the most important things to understand is that your response is not a sign that there is something fundamentally wrong with you. Your nervous system has been trying to protect you. Sometimes it simply continues using an old alarm system in situations where the original danger is no longer present. Recovery involves helping your mind and body learn something new:
“That happened then. I am here now. I am safe enough in this moment.”
This doesn't mean forcing yourself to stop feeling. It means gradually developing a greater sense of safety, understanding your responses and, when appropriate, processing the experiences that may still be affecting you.
You don't have to understand everything before asking for help
You don't need to have a diagnosis of PTSD to seek support. You don't need to be able to explain exactly why you are reacting and you don't have to tell your entire story in your first counselling session. Therapy can begin with simply understanding what is happening for you now. Together, we can become curious about the patterns, triggers and responses that are affecting your life and consider what might help.
Often healing begins when we stop asking “Why can't I just get over this?” and start asking:
“What is my mind and body trying to tell me?”
How Cosmos Counselling can help
