Trauma
A sudden loss, an accident, an assault or a life-threatening event: experiences that shake a person’s sense of safety, and what may follow.
01
What it is
A traumatic event is one in which a person experiences, witnesses or learns that their own life or someone else’s is in danger. The same event does not leave the same mark on everyone; its severity, the person’s history and the support they receive shape the outcome.
Reactions after trauma are not a sign of weakness; they are the mind and body trying to protect themselves from danger. Most people recover with time and support.
Information on violence and social conflict is on a separate page: Violence and social conflict.
02
Expected reactions
- Trouble falling asleep, waking often, nightmares
- Startling at sudden noises, feeling constantly on guard
- Going over the event again and again — or not wanting to think about it at all
- Restlessness, anger, crying spells, emotional numbness
- Difficulty concentrating, forgetfulness
- Headaches, stomach problems, muscle tension, fatigue
- Guilt, shame or “why did I survive” thoughts
- Avoiding places, people or conversations that bring back the event
These are normal reactions to an abnormal event. For most people they ease noticeably within a few weeks, with safety, routine and social support.
03
Before, during and after
Before
- Strong social ties and a reliable support network are the most important protective factors.
- Knowing in advance about trauma reactions makes what follows easier to understand.
- Having people trained in psychological first aid in institutions and schools.
During
- Safety first: move away from danger and call the emergency lines.
- Be a calm, reassuring presence next to the person.
- Give verified information; do not promise what cannot be promised.
After
- Know that reactions in the first weeks are normal, and return to daily routines.
- Stay connected; avoid isolation.
- Seek specialist support if reactions persist or worsen.
04
What to do
- Safety first: make sure the person is safe and their basic needs are met.
- Listen, but do not push them to talk or press for details.
- Try to bring back daily routines — sleep, meals, short walks — in small steps.
- Stay connected with loved ones; try not to be alone.
- Avoid alcohol and stimulants; they may bring short relief but slow recovery.
- Notice your own feelings and limits too; carrying someone else’s burden is tiring.
05
When to seek support and where to turn
- Reactions last longer than four weeks or get worse
- Daily tasks such as going to work or school or caring for children become impossible
- Use of alcohol, medication or other substances increases
- The person isolates themselves completely and talks to no one
- There are thoughts of harming oneself or others — in this case, without waiting
If life is in danger
Do not wait: call 112, or 155 for violence. All emergency numbers
For specialist support
Your family doctor or the mental health units of state hospitals can refer you to the right service.
