Signs of post-traumatic stress
Post-traumatic stress can show up weeks after an event in ways people don't always recognise - here are the signs to watch for.
Sometimes the effects of a frightening or overwhelming experience only become clear weeks or months later. Knowing the signs of post-traumatic stress can help you recognise when support is needed, for yourself or someone you care about.
What it is
Post-traumatic stress describes a cluster of reactions that can develop after experiencing or witnessing a distressing event, such as a violent crime, serious accident, natural disaster or the sudden loss of someone close. The mind and body can remain in a state of heightened alert long after the danger has passed, as if still trying to protect you from a threat that is no longer there. This is the nervous system doing its job, just in an unhelpful way when it does not settle down. Only a qualified professional can assess whether someone is experiencing PTSD - the signs below are simply what to watch for.
Signs to notice
- Reliving the event through intrusive memories, nightmares or flashbacks
- Avoiding places, people, conversations or activities connected to the event
- Feeling constantly on edge, easily startled, or scanning for danger
- Difficulty sleeping or concentrating
- Emotional numbness, or feeling disconnected from people and activities you used to enjoy
- Persistent guilt, shame or blaming yourself for what happened
- Irritability, angry outbursts, or a shortened fuse
- Physical symptoms such as a racing heart, sweating or nausea when reminded of the event
What helps
- Recognise that these reactions are common responses to trauma, not a sign of weakness or failure.
- Keep a predictable daily routine where possible - the body finds safety in rhythm.
- Stay connected to supportive people, even in small ways, rather than withdrawing completely.
- Practise grounding techniques, such as naming five things you can see and four you can hear, to help bring your mind back to the present moment during flashbacks.
- Limit alcohol and other substances, which can worsen sleep and intensify symptoms over time.
- Be patient and gentle with yourself. Trauma recovery is not linear, and setbacks do not mean you are failing.
