Trauma triggers and flashbacks

If a sound, smell or situation suddenly pulls you back into a distressing memory, you are not losing control - your brain is trying to protect you using an old alarm system. Understanding triggers and flashbacks can make them feel less frightening.

What it is

A trigger is anything - a sound, smell, place, date or interaction - that reminds the brain of a past traumatic event, even if there is no danger in the present moment. A flashback goes a step further: it can feel as though the traumatic event is happening again right now, complete with the same fear, physical sensations and emotions. This happens because trauma memories are sometimes stored differently to ordinary memories, in a way that is less linked to time and place. The nervous system reacts to the trigger as if the threat is current, not in the past.

Signs to notice

• A sudden shift in mood, panic or fear with no obvious present-day cause
• Physical reactions such as a racing heart, sweating, shaking or nausea
• Feeling as though you are reliving the event, sometimes losing awareness of your current surroundings
• Wanting to flee, freeze or become defensive without understanding why
• Avoiding certain places, people, sounds or dates that seem to bring on these reactions
• Feeling disoriented or embarrassed afterwards, unsure of what just happened

What helps

• Learn your personal triggers over time, without judgement. Noticing patterns can help you prepare.
• Use grounding techniques during a flashback: name the date, your location, and five things you can see around you to anchor yourself in the present.
• Try slow, deliberate breathing - a longer exhale than inhale can help calm the body's alarm response.
• Keep something with you that engages your senses in the present, such as a strong mint, a textured object, or a piece of music that feels safe.
• Let trusted people around you know what a flashback can look like for you, so they can support you calmly if it happens.
• Avoid using alcohol or substances to numb triggers, as this tends to worsen symptoms over time.

When to reach out for help

Reach out to a professional if flashbacks or triggers are frequent, intense, or interfering with your work, relationships or safety, such as while driving. A trained counsellor can help you process the underlying trauma safely, using approaches suited to your situation, rather than just managing symptoms as they arise.
