Trauma and stress are among the most penetrating and complex issues in modern mental health. They concern not only individual responses to unexpected events but also the deep psychological impact of life experiences characterized by loss of control, helplessness, and constant threat. Many people fail to recognize that their chronic anxiety, irritability, depression, insomnia, avoidance, and difficulty forming close relationships stem from unresolved traumatic experiences or stress reactions. Understanding trauma and stress is the starting point for self-healing.

D-1. Basic Definitions of Trauma and Stress

traumaPsychological distress refers to a state in which the psychological system is unable to process and integrate life-threatening, extreme fear, humiliation, or loss of control experiences, leading to a deep freeze, a fracture, or a persistent recurrence. These experiences can be one-time (such as a car accident, the death of a loved one, or school violence) or chronic (such as long-term domestic violence, neglect, devaluation, poverty, war, or sexual assault).

stressStress is the body's response to external or internal stressful events (stressors). It's not always negative; sometimes, moderate stress can help unleash potential. However, when stress exceeds an individual's ability to regulate, or becomes a persistent, chronic stressor, it can trigger dysfunction in both the mind and body systems. Especially without an outlet or support, stress can easily escalate into a "traumatic stress response."

D-2. Classification of trauma and stress problems

1. Acute stress reaction: refers to the mental disorder state that occurs in an individual in a short period of time after a major trauma.
2. Post-traumatic stress disorder: A persistent cluster of psychiatric symptoms that usually appears more than one month after a major traumatic event.
3. Complex trauma: refers to multiple, repetitive injuries over a long period of time.
4. Adjustment disorder: refers to the individual's adjustment disorder when encountering life changes.
5. Stress-related physical and mental disorders: including physiological diseases caused by chronic stress.

D-3. The Psychological Mechanisms of Trauma: Freezing and Fracture

• Unable to escape、Irresistible、Unable to express、Cannot be understood

These four "failures" form the core of the traumatic experience. The brain's amygdala is responsible for identifying threats, while the prefrontal cortex regulates emotions and cognition. When a traumatic event occurs, the amygdala becomes highly activated, suppressing the prefrontal cortex, causing the individual to enter the three survival responses of "fight, flight, or freeze." If the event is too intense or prolonged, this mechanism may fail to automatically recover, resulting in a long-term "frozen state."

D-4. The physical and mental response to stress: The "erosion" of chronic stress

• Nervous system disorders: shallow sleep, frequent dreams, headaches, and fatigue
• Endocrine imbalance: decreased immunity, skin allergies, menstrual disorders
• Mood and behavior changes: anxiety, irritability, difficulty concentrating, overeating or drinking
• Damaged self-identity: constant self-blame, doubt, and loss of hope for the future

D-5. The hidden nature of trauma and stress

• Suppressing emotions with “rational explanations” (e.g., “That was just a childhood thing, it’s not important anymore”)
• Using efficiency and excessive work to cover up inner emptiness or alertness
• Unconscious avoidance of certain people, things, and places without explanation
• Frequent clinging or avoidance behaviors in close relationships
• Unusual reactions to unexpected events (small things triggering outbursts)

D-6. Trauma and stress can be healed

• Mindfulness practice: Helps stabilize the present moment and reduce hypervigilance
• Cognitive behavioral therapy (CBT): Restructuring negative cognitions associated with the event
• Eye Movement Desensitization and Reprocessing (EMDR): Promoting the brain's integration of traumatic memories
• Inner Child Work: Healing Early Relationship Trauma
• Body-focused therapy: Rebuilding trust in your body's signals
• Emotional expression in secure relationships: slowly rebuilding trust and belonging
