Understanding trauma responses: why your body reacts before you think

Waves breaking against dark coastal rocks under a heavy grey sky

After a traumatic experience, many people notice reactions that seem out of proportion or out of their control. Understanding why can make them feel less confusing.

The body’s alarm system

When we face danger, the brain’s threat system prepares the body to fight, run or freeze. After trauma, that system can stay on high alert, responding to reminders of the event as if the danger were happening again.

Common reactions

  • Feeling jumpy, on edge or easily startled
  • Difficulty sleeping or nightmares
  • Avoiding places, people or conversations that bring back memories
  • Feeling numb or disconnected
  • Irritability or anger that seems to come from nowhere

These are common responses to overwhelming experiences. They are not a sign of weakness.

When to seek support

If reactions are persisting, affecting your sleep, work or relationships, or you’re relying on alcohol or other ways to cope, it may help to talk with a psychologist or your GP. Trauma-focused therapy is one of a range of options that can help people understand and manage these responses.
