Yes, caffeine can worsen PTSD symptoms because it's a stimulant that increases anxiety and arousal, mimicking or amplifying hyperarousal, insomnia, and panic attacks, which are core PTSD features, by affecting stress hormones like cortisol and the HPA axis. People with PTSD often have heightened stress responses, making them more sensitive to caffeine's effects, leading to increased nervousness, faster heart rate, and disrupted sleep, so reducing intake is often recommended.
Some example PTSD triggers include:
PTSD stems from a single traumatic event, while Complex PTSD (C-PTSD) arises from prolonged, repeated trauma (like abuse or captivity) and includes core PTSD symptoms plus additional issues with emotional regulation, negative self-concept (shame, worthlessness), and relationship difficulties, as recognized by the ICD-11. Both involve fear, flashbacks, and hypervigilance, but C-PTSD reflects deeper disturbances in self-organization due to ongoing interpersonal harm.
Here are some things to avoid:
Yes, people with PTSD and C-PTSD can have high levels of cortisol – but some also have low levels – this is why there's no 'test' available for PTSD or C-PTSD using cortisol levels.
Neuroendocrine studies in individuals with PTSD have demonstrated elevated basal cerebrospinal fluid corticotropin-releasing hormone concentrations and contradictory results from peripheral measurements, exhibiting low 24 hours excretion of urinary free cortisol, low or normal circulating cortisol levels or even high ...
10 ways to relax when you have PTSD
They can also be internal, such as certain thoughts, emotions, or physical sensations that are similar to those experienced during the traumatic event. Some common triggers for PTSD and C-PTSD flashbacks include loud noises, crowds, physical contact, or the anniversary of the traumatic event.
When our brain then recognises similarities between our present situation and our past trauma (e.g. a colour, smell or noise), it can activate the fight, flight, freeze, flop or friend response, even if we're not currently in danger.
The highest form of PTSD is considered extreme PTSD, often manifesting as Complex PTSD. It involves chronic symptoms, emotional detachment, and deep psychological distress from prolonged trauma.
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.
Doctors may misdiagnose people with CPTSD as having BPD. Both conditions involve emotional instability and fear of abandonment.
Anger and violent behavior
After trauma, your nervous system may become overly sensitive, and you may feel a lot of anger at times. Your anger may cause you to feel bad about yourself, lose your temper, or do reckless things. You may distance yourself from people who want to help.
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.
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.
Signs of PTSD involve re-experiencing the trauma (flashbacks, nightmares), avoiding reminders, experiencing negative thoughts/moods (numbness, guilt, fear), and heightened arousal (irritability, jumpiness, sleep issues), disrupting daily life and relationships, often accompanied by physical reactions like a racing heart or sweating.
The most common events that can lead to PTSD include: Combat exposure. Childhood physical abuse. Sexual violence.
Flashbacks play a significant role in the experience of PTSD. They are characterized by vivid and disturbing recollections of the traumatic event, which can feel as if the person is reliving the experience all over again.
Exercise is perhaps one of the most tried-and-true methods for managing symptoms related to C-PTSD. Our bodies want to move. They need to move. And when you are experiencing stress from past trauma, that need is even greater.
avoid crowding the person. don't touch or hug them without permission. try not to startle or surprise them.
There are 3 SSRI/ SNRI medications that are recommended for PTSD:
To get rid of excess cortisol, focus on stress reduction through mindfulness, deep breathing, and quality sleep, alongside a balanced diet rich in whole foods, omega-3s, magnesium, and B vitamins, while limiting sugar, processed items, and caffeine; regular, moderate exercise and connecting with nature also significantly help manage stress and lower cortisol levels.
“Cortisol face” isn't an official diagnosis
But this facial feature has been described in the medical field — we've called it “moon face” — and it absolutely can be induced by high cortisol levels. It's a combination of fat accumulation and soft issue swelling, associated with thinning of the skin.
In humans, the peak level secretion occurs in the morning (07:00–08:00 a.m.), which is considered the active phase, while its lowest secretion is around 02:00–04:00 a.m. at night [44,47]. Figure 2 demonstrates the circadian rhythm of cortisol.
