We often think behaviour is about attitude, personality, or choice. But for many people with adverse childhood experiences, what looks like “overreaction” is often a nervous system response to something that feels unsafe, threatening, or too familiar. If you work with people, lead people, coach people, or support people in any way, learning to notice triggers is one of the most useful skills you can develop. Not because it makes you walk on eggshells. But because it helps you respond with more accuracy, less judgement, and far better results. What is a trigger? A trigger is not just “something annoying”. It is something that activates a person’s emotional memory, threat system, or protective response. For someone with adverse childhood experiences, the trigger may be linked to past experiences of fear, shame, unpredictability, rejection, criticism, control, or powerlessness. That means the present moment may be activating an old wound. And once that happens, the person may stop responding to what is happening now and start responding to what it reminds them of. Common triggers to watch for Triggers are not always dramatic. In fact, they’re often subtle. Here are some of the most common ones: - A sharp tone of voice. - Feeling ignored or dismissed. - Being interrupted. - Sudden change. - Being told what to do. - Public correction. - Being watched too closely. - Unclear expectations. - Waiting without information. - Feeling trapped or cornered. - Being compared to others. - Sarcasm, criticism, or humiliation. What matters is not whether the trigger seems “small” to you. What matters is what it means to the person. The signs someone may be getting triggered A person does not always say, “I’m triggered.” Often, you’ll notice it in their behaviour. They may: - go quiet, - become defensive, - raise their voice, - talk faster, - fidget, - avoid eye contact, - shut down, - laugh nervously, - become controlling, - leave the room, - or suddenly seem argumentative.
