When PTSD is triggered, it looks like an intense, sudden reaction where a person relives the trauma (flashbacks, nightmares) or experiences overwhelming fear, panic, and physical symptoms (racing heart, shaking), often accompanied by avoidance, irritability, difficulty concentrating, and feeling constantly "on guard," as reminders of the event activate their body's stress response. Triggers can be obvious (smells, sounds) or subtle (feelings, situations), leading to a feeling of being unsafe and detached from reality.
Symptoms of changes in physical and emotional reactions, also called arousal symptoms, may include: Being easily startled or frightened. Always being on guard for danger. Self-destructive behavior, such as drinking too much or driving too fast.
While there isn't one official list of exactly 17 symptoms, C-PTSD symptoms often include core PTSD issues (flashbacks, hypervigilance, avoidance, nightmares) plus difficulties with emotional regulation, self-perception (shame, worthlessness), relationships (trust issues, isolation), and severe dissociative or somatic symptoms (feeling detached, chronic pain) due to prolonged trauma, often presented as distinct points by various mental health sources.
Coping with the Symptoms of PTSD
Complex PTSD and emotional flashbacks
If you have complex PTSD you may be particularly likely to experience what some people call an 'emotional flashback', in which you have intense feelings that you originally felt during the trauma, such as fear, shame, sadness or despair.
Symptoms of a PTSD Episode
Some of the most common symptoms include: Flashbacks or vivid re-experiencing of the traumatic event. Sudden bursts of anger or irritability. Hypervigilance or exaggerated startle response.
Common triggers for individuals with complex PTSD can include specific sights, sounds, smells, or even certain words or phrases that evoke memories of traumatic events. For example, a person who experienced domestic violence may be triggered by loud or aggressive arguments.
4. How long will a PTSD episode last? Episodes can last from minutes to hours. The duration depends on the person and the intensity of the trigger.
The 'fight or flight' response is how people sometimes refer to our body's automatic reactions to fear. There are actually 5 of these common responses, including 'freeze', 'flop' and 'friend', as well as 'fight' or 'flight'.
Breathing and relaxation exercises
Try doing one of these when you're feeling distressed. You might also find it helpful to do more exercise and physical activity, to help calm your mind and body.
Relaxation and sleep may become difficult, leading to symptoms such as insomnia or restless sleep. Additionally, hyperarousal can manifest as irritability, anger, aggressive behaviour, and difficulty concentrating due to racing thoughts or distractibility.
avoid crowding the person. don't touch or hug them without permission. try not to startle or surprise them.
Pete Walker's “Complex Trauma: From Surviving to Thriving,” explores the four F's of complex trauma, fight, flight, freeze, and fawn, to help survivors understand their coping mechanisms and reactions, and begin to work towards actions that may better serve them in their life and relationships.
PTSD is more than an emotional struggle — it physically rewires the brain, altering how fear is processed, memories are stored and emotions are regulated. Key brain regions affected include the amygdala, bed nucleus of the stria terminali, prefrontal cortex and hippocampus.
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.
Types of Triggers and responses to them
Signs of childhood trauma
The belief is emotions and traumatic experiences can become trapped in the body, and somatic therapy helps release this pent-up tension and emotions. Somatic therapy uses body awareness, breathwork and movement exercises to be more aware of bodily sensations and release stored emotions.
Recognizing Emotional Trauma Triggers
Some examples of emotional trauma triggers linked to past trauma are sights, sounds, smells, situations, or people. Although not inherently dangerous, these cues are perceived as threats due to their traumatic associations, triggering intense emotional and physical reactions.
You might notice that particular places, people or situations can trigger a flashback for you, which could be due to them reminding you of the trauma in some way. Or you might find that flashbacks seem to happen at random. Flashbacks can last for just a few seconds, or continue for several hours or even days.
Left unaddressed, PTSD can worsen over time, damaging relationships, affecting job or school performance, and significantly increasing the risk of substance use and suicide.
Changes in arousal and reactivity: People with PTSD may describe being irritable and having angry outbursts, behaving recklessly or in a self-destructive way, being overly watchful of their surroundings in a suspecting way, being easily startled, or having problems concentrating or sleeping.
PTSD is diagnosed by a psychiatrist through a mental health assessment. Your GP should carry out an initial assessment to decide what care you need. Your assessment should include information about your physical needs, mental needs, social needs, and risk.
The symptoms of complex PTSD are similar to symptoms of PTSD, but may also include: feelings of worthlessness, shame and guilt. problems controlling your emotions. finding it hard to feel connected with other people.
Yelling can serve as a powerful trigger for individuals with PTSD, reigniting their traumatic memories and plunging them into a state of overwhelming distress. The aggressive and forceful nature of yelling can mimic the threatening and dangerous situations that caused their PTSD in the first place.
