Why Trauma Hijacks the Brain - and How to Reclaim Calm

Understanding the Brain’s Response to Threat

When we experience intense fear or anxiety, our brain activates its ancient survival system - commonly known as the ‘fight or flight’ response. In this state, the primitive part of our brain records sensory details with remarkable precision: sights, sounds, smells, and touch.

This system is designed to protect us. If we encounter similar cues in the future, our brain instantly recognises the threat and prompts us to act - either by fighting or fleeing. While this automatic response helps us survive, it can also become deeply disruptive in everyday life.

Brain imaging studies show that trauma can alter the brain’s natural balance. The emotional and associative centres - often referred to as the ‘primitive brain’ - become dominant, while the logical, reasoning circuits are sidelined.

Therapy helps restore this balance, allowing the brain to return to its usual rhythm and function.

Our primitive brain, located in the brain stem, evolved long before our higher-order thinking structures. Its core purpose is simple: detect danger and keep us safe. But when trauma rewires this system, it can leave us feeling constantly on edge - even when the original threat is long gone.

When we feel threatened, our adrenal glands release cortisol, sending blood to our muscles and preparing us to act. This surge of energy can make it hard to sit still or feel calm.

Many people try to escape this discomfort by distracting themselves or using substances like alcohol or drugs. While understandable, these avoidance strategies don’t resolve the underlying emotional triggers. Instead, they leave us vulnerable to being ‘re-triggered’ - reliving the distress when we least expect it.

Specialised trauma therapies are designed to reduce the emotional intensity tied to traumatic memories. Over time, these triggers lose their power. Clients often find they can stay present, feel calmer, and respond to life’s challenges without being overwhelmed by the past.

These approaches require advanced training beyond standard psychology or social work degrees.
