A trauma trigger is a
psychological stimulus that prompts involuntary recall of a previous
traumatic experience. The stimulus itself need not be frightening or traumatic and may be only indirectly or superficially reminiscent of an earlier traumatic incident, such as a scent or a piece of clothing.
Triggers can be subtle, individual, and difficult for others to predict.
A trauma trigger may also be called a trauma stimulus, a trauma

or a trauma reminder.
The process of connecting a traumatic experience to a trauma trigger is called traumatic coupling.

Avoiding a trauma trigger, and therefore the potentially extreme reaction it provokes, is a common behavioral symptom of
posttraumatic stress disorder
Post-traumatic stress disorder (PTSD) is a mental disorder that develops from experiencing a Psychological trauma, traumatic event, such as sexual assault, domestic violence, child abuse, warfare and its associated traumas, natural disaster ...
(PTSD) and
post-traumatic embitterment disorder (PTED), a treatable and usually temporary condition in which people sometimes experience overwhelming emotional or physical symptoms when something reminds them of, or "triggers" the
memory of, a traumatic event.
Long-term avoidance of triggers increases the likelihood that the affected person will develop a disabling level of PTSD.
Identifying and addressing trauma triggers is an important part of treating PTSD.
A ''
trigger warning'' is a message presented to an audience about the contents of a piece of media, to warn them that it contains potentially distressing content. A more generic term, which is not directly focused on PTSD, is ''content warning''.
Triggers
The trigger can be anything that provokes fear or distressing memories in the affected person, and which the affected person associates with a previous traumatic experience. Just as
trauma is not merely an unpleasant or adverse experience, a trauma trigger is not merely something that makes a person feel uncomfortable or offended.
Some common triggers are:
* a particular smell

aftershave product or
perfume

*a particular taste
– such as the food eaten during or shortly before a traumatic experience
* a particular sound
– such as a helicopter or a song
*a particular texture
* certain times of day
– for example, sunset or sunrise
* certain times of year or specific dates – for example, autumn weather that resembles the affected person's experience of the weather during the
September 11 attacks

* places
– for example, a bathroom, or all bathrooms

especially a person who was present during a traumatic event or resembles someone involved in that event in some respect

* the position of the body
* physical pain
* emotions – such as feeling overwhelmed, vulnerable, or not in control
*a particular situation – for example, being in a crowded place
The trigger is usually personal and specific. However, it need not be closely related to the actual experience. For example, after the

as a trigger, which they associated with the sound of
sirens they heard during the war, even though the resemblance between the two sounds is limited.
The realistic portrayal of graphic violence in visual media may expose some affected people to triggers while watching movies or television.
Experiences

People who have experienced trauma and who have developed trauma triggers may panic when the trigger is experienced, especially if it is unexpected.
For example, the noise of fireworks may seem unbearable to a combat veteran whose trauma is coupled with sudden, loud noises as the trigger.
Trigger warnings
Trigger warnings, sometimes called content warnings, are warnings that a work contains writing, images, or concepts that may be distressing to some people.
Content warnings have been widely used in mass media without any connection to trauma, such as the US

).
In the case of non-fiction books and online videos, only specific chapters or segments may have trigger warnings, providing timestamps and page numbers that allow the audience to easily skip only certain parts, rather than the entire work. This may be more difficult to employ in works of fiction, where skipping certain parts disrupts the narrative flow.
Controversy in higher education
The idea of giving content warnings to university students about their coursework has been disputed and politicized.
Much of the dispute centers around content warnings given to all students about the presence of generally uncomfortable subjects in the curriculum, such as racism and misogyny.
There is no significant dispute over providing
reasonable accommodation
A reasonable accommodation is an adjustment made in a system to accommodate or make fair the same system for an individual based on a proven need. That need can vary. Accommodations can be religious, physical, mental or emotional, academic, or em ...

ballistic pendulum demonstration will produce loud sounds.
In 2014, the

criticized the use of general content warnings in university contexts, stating, "The presumption that students need to be protected rather than challenged in a classroom is at once infantilizing and anti-intellectual. It makes comfort a higher priority than intellectual engagement and...it singles out politically controversial topics like sex, race, class, capitalism, and colonialism for attention." This view is supported by some professors such as
Richard McNally, professor of psychology at Harvard, and some psychiatric medical practitioners, such as Metin Basoglu and Edna Foa.
They believe that trigger warnings increase avoidance behaviors by those with PTSD which makes it harder to overcome the PTSD, create a culture that decreases resilience, and more geared towards political

". Other supportive professors have stated that "the purpose of trigger warnings is not to cause students to avoid traumatic content, but to prepare them for it, and in extreme circumstances to provide alternate modes of learning."
Universities have taken different stances on the issue of trigger warnings. In a letter welcoming new undergraduates, the

took the opposite position in 2014, passing a non-binding resolution in support of mandatory trigger warnings for classes that could contain potentially upsetting material. Professors were encouraged to make students aware of such material and allow them to skip classes that could make them feel uncomfortable.
Limited value for general use
Although the subject has generated political controversy, research suggests that trigger warnings are neither harmful nor especially helpful. Among people without traumatic experiences, "trigger warnings did not affect anxiety responses to potentially distressing material in general."
Furthermore, studies disagree on whether trigger warnings cause transient increases in anxiety in those without traumatic experiences.
For participants who self-reported a posttraumatic stress disorder (PTSD) diagnosis, or for participants who qualified for probable PTSD, trigger warnings had little
statistically significant effect.

s on feelings of avoidance, decreased resilience, or other negative outcomes have been "trivial" in controlled research environments.
While trigger warnings have garnered significant debate, few studies have investigated how students typically respond to potentially triggering material. In a 2021 study, 355 undergraduate students from four universities read a passage describing incidents of both physical and sexual assault. Longitudinal measures of subjective distress, PTSD symptoms, and emotional reactivity were measured. Greater than 96% of participants read the triggering passage even when given a non-triggering alternative to read. Of those who read the triggering passage, those with triggering traumas did not report more distress although those with higher PTSD scores did. Two weeks later, those with trigger traumas and/or PTSD did not report an increase in trauma symptoms as a result of reading the triggering passage. Moreover, students with relevant traumas do not avoid triggering material and the effects appear to be brief. Also, students with PTSD do not report an exacerbation of symptoms two weeks later as a function of reading the passage.
History
Trauma triggers have been recognized by medical professionals since the 19th century.
