Definition and Overview
Burnout syndrome is a job-related exhaustion condition in which three core symptoms occur due to chronic occupational stress: emotional exhaustion, depersonalization (cynicism), and reduced personal accomplishment.
In 2019, the World Health Organization (WHO) officially registered burnout as an occupational phenomenon in ICD-11 (code Z73.0). This clearly states that burnout is a condition related to the occupational environment, not a disease. The standard measurement tool is the Maslach burnout inventory (MBI), which is the most widely used in research and clinical practice worldwide.
Causes and Pathophysiology
Occupational environmental factors
Excessive workload, lack of autonomy, insufficient compensation, unfair treatment, inconsistency between work and values, and lack of community are the main occupational environmental factors that cause burnout. This chronic stress continuously stimulates the hypothalamic-pituitary-adrenal (HPA) axis.
Autonomic nervous system changes
HPA axis hyperactivation due to chronic stress manifests as abnormal cortisol secretion patterns (decreased morning cortisol awakening response, flattening of circadian cortisol fluctuations). The sympathetic nerve continues to be overactivated, parasympathetic nerve activity decreases, and heart rate variability (HRV) decreases.
neurobiological mechanism
Decreased functional connectivity of the prefrontal cortex and increased amygdala reactivity have been reported in burnout states. This leads to a decline in the ability to control emotions and hypersensitivity to negative stimuli.
symptoms
3 key symptoms
- Emotional exhaustion: Feeling emotionally drained and having nothing more to give, extreme fatigue.
- Depersonalization (cynicism): A callous or distant attitude toward those working (colleagues, customers, patients)
- Decreased sense of accomplishment: loss of work efficacy and meaning, lower self-evaluation
physical symptoms
Chronic fatigue, headaches, muscle pain, digestive problems (irritable bowel syndrome, gastrointestinal disorders), decreased immune function (frequent colds), and sleep disorders are common.
Concomitant mental health problems
The co-occurrence rate of burnout and depressive disorder is approximately 49%, and anxiety disorders and insomnia are also common. The risk of alcohol abuse also increases.
diagnosis
Maslach Burnout Inventory (MBI)
The MBI consists of three subscales: emotional exhaustion (9 items), depersonalization (5 items), and personal accomplishment (8 items), and each item is rated on a 7-point Likert scale. There are standards for each occupational group.
Differential diagnosis
Depression disorder, anxiety disorder, chronic fatigue syndrome, hypothyroidism, sleep disorder, etc. must be distinguished. Blood tests (thyroid function, blood sugar, iron, vitamin D) and sleep evaluation may be needed.
Autonomic function evaluation
Heart rate variability (HRV) measurement is used to objectively evaluate the state of autonomic balance. HRV decline is reported to be associated with chronic stress and burnout states.
treatment
Improved work environment
The key is to improve occupational environmental factors, which are the root cause of burnout. This includes adjusting workload, expanding autonomy, fair compensation, and strengthening social support. Organization-level interventions have more lasting effects than individual-level interventions.
Cognitive Behavioral Therapy (CBT)
CBT is effective in modifying maladaptive thinking patterns and behaviors associated with burnout. Acceptance and Commitment Therapy (ACT) is also used to alleviate burnout symptoms by improving psychological flexibility.
Mindfulness-Based Stress Reduction (MBSR)
The 8-week MBSR program has been confirmed through clinical research to be effective in lowering stress reactivity and restoring autonomic balance. Relieves sympathetic nerve overactivity through attention training and body sensation awareness.
Autonomic recovery strategy
Relaxation training (abdominal breathing, progressive muscle relaxation), regular aerobic exercise, and sleep hygiene management contribute to restoring autonomic balance. Studies have shown that regular physical activity reduces the risk of burnout and depression.
Social support and recovery activities
Maintaining emotional support relationships with trusted colleagues or family, and psychological detachment through non-work activities (hobbies, contact with nature) are important in recovering from burnout.
