Have you ever wondered ‘why do I react like this’ or ‘I know I’m safe, so why does my body act like I’m not’?
This is your nervous system doing what evolution designed it to do – to keep you alive and safe. But sometimes it can get a little stuck on knowing when and how to settle.
Many people searching for a psychotherapist or psychologist in Margaret River are trying to understand how their reactions feel out of proportion, whether it’s sudden anger, shutdown, anxiety, panic, emotional overwhelm, or numbness.
Often, trauma sits quietly underneath these nervous system responses. To better understand trauma, we need to also understand the nervous system.
Your Nervous System Is Designed for Survival
The nervous system’s primary job is not happiness (unfortunately).
Its main job is about survival and keeping you alive
Your nervous system constantly scans for anything that could alert to:
- Safety
- Danger
- Rejection
- Pain
This scanning for threats largely outside of conscious awareness, which is why simply ‘thinking’ you’re safe doesn’t make the nervous system feel safe. Before you think, your nervous system has already decided how to it wants to respond.
When it detects threat, it activates protective responses designed to keep you alive. As you can imagine, this is extremely helpful when our ancestors faced threats from dangers from predatory animals:
- Fight
- Flight
- Freeze
- Flop
- Fawn / Friend (this function won’t be discussed as it includes cognitive aspects)
You are not broken and these are not personality flaws. They are survival adaptations from our brain’s evolutional strategy.
Trauma Is How Your Nervous System Learned
Trauma is often misunderstood as a single external event. However, psychologically, traumatology actually refers to experiences that overwhelmed your nervous system.
Traumatic experiences could include:
- Abuse or neglect
- Emotional invalidation
- Sudden loss
- Chronic criticism
- Exposure to anger or unpredictability
- Medical or relational trauma
The nervous system adapts when threats are multiple, repeated, cumulative, or prolonged. It becomes more sensitive, quicker to react, and sometimes slower to settle.
This is highly adaptive learning to reduce harm and survive threats.
Why You React, Or Not At All
Trauma responses tend to show up in patterns:
Hyperarousal (Fight/Flight)
You may notice:
- Disproportionate anxiety
- Panic attacks
- Irritability or anger
- Restlessness
- Overthinking
- Difficulty relaxing
This is your system scanning for danger and preparing to act to keep you safe.
Hypoarousal (Freeze/Flop)
You may experience:
- Numbness
- Emotional flatness
- Fatigue
- Dissociation
- Excessive sleeping
- Avoidance
This is the nervous system conserving energy when escape doesn’t feel possible.
Rapid Shifts
Some people swing between hyperarousal and hypoarousal, such as feeling overwhelmed one moment then emotionally shutdown the next.
Or, someone in hyperarousal might crave hypoarousal. For example, someone that feels anxious all day at work might come home and want cannabis or alcohol to ‘zone out’.
The Window of Tolerance
Psychologist Dan Siegel famously introduced the concept of the window of tolerance. This explains the range in how people can feel emotions safely, without becoming overwhelmed or shutting down.
Trauma narrows the range of the window, meaning the emotional ‘safe zone’ is smaller and it’s much easier to fall into hyper or hypoarousal.
Even small stressors can push someone into:
- Panic and anger (hyper)
- Collapse and numbness (hypo)
Therapy helps to widen this window over time, and helps people come back into the window when they shift outside it.
Why Insight Alone Doesn’t Stop the Reaction
Many people say:
“I understand where this comes from but I still react.”
This is because trauma lives in the nervous system and beyond just our thoughts.
Talking helps, but change often requires a deeper integration of:
- Emotional processing
- Regulating experiences within a safe relationship
- Gradual exposure to previously overwhelming feelings
- Integrating fragmented memory
This is why trauma-informed evidence-based psychological therapies such as EMDR approaches can be effective. They work on both a cognitive and physiological level.
Trauma Responses Made Sense Once
You are not broken, your reactions likely made sense at some point in your life.
- Hypervigilance may have kept you safe from abuse.
- Pleasing others may have prevented rejection and abandonment.
- Emotional shutdown may have protected you from overwhelm or pain.
You are not broken, and the problem isn’t that your nervous system adapted.
What may be happening is that your nervous system may still be reacting to old threats in present-day situations.
Healing Is About Safety, Not Forcing Change
The nervous system changes in the presence of safety, and safety alone.
- Not pressure.
- Not self-criticism.
- Not “just think differently.”
A consistent, regulated therapeutic relationship allows the nervous system to gradually learn ‘I am safe enough now’. This is supported by consistent and regulated practices, such as yoga and walking in nature.
Over time, reactions become less automatic and more flexible, and you develop more choice over how your body responds.
If You’re Noticing These Patterns
If you’re searching for a psychologist in Margaret River because your reactions feel difficult to manage, it may be helpful to understand them through the lens of the nervous system.
Trauma-informed psychological therapies can support nervous system regulation, as they focus on:
- Regulation
- Emotional safety
- Processing past experiences
- Building resilience
