Short answer: burnout is recognized by three main dimensions defined by the World Health Organization: persistent energy exhaustion, growing mental distance from work (cynicism), and reduced professional efficacy. If you have been feeling for at least a few weeks that rest no longer restores your strength, work causes increasing indifference or irritability, and tasks you previously performed easily now require disproportionately much effort, it is worth assessing the risk of burnout more seriously.
What is burnout according to the WHO?
In 2019, the World Health Organization included burnout in the International Classification of Diseases ICD-11 (code QD85) as an occupational phenomenon. According to the WHO definition, burnout is a syndrome resulting from chronic workplace stress that has not been successfully managed. It is characterized by three dimensions: feelings of energy depletion or exhaustion; increased mental distance from one's job, or feelings of negativism or cynicism related to one's job; and reduced professional efficacy.
Important to know: in ICD-11, burnout is classified not as a medical condition, but as an occupational phenomenon. However, this does not mean it is not dangerous. If left unaddressed for a long time, burnout increases the risk of depression, anxiety disorders, cardiovascular diseases, and long-term disability.
What are the 12 signs of burnout?
These signs are grouped according to the three dimensions defined by the WHO. The more of them you recognize and the longer they persist, the more likely it is that you are dealing with burnout rather than temporary fatigue.
Energy exhaustion
- Persistent fatigue that is not relieved by rest. Weekends or even vacations no longer restore your strength. This is one of the most reliable distinguishing marks: you recover from normal fatigue after resting, but not from burnout.
- Sleep disturbances. Difficulty falling asleep because your mind "won't stop," or you sleep a lot but wake up tired.
- More frequent physical ailments. Headaches, muscle tension, digestive issues, and more frequent colds due to a weakened immune system.
- Emotional exhaustion. A feeling that there is "nothing left to give" inside: even small requests seem too demanding.
Cynicism and detachment
- Indifference to work that was previously meaningful. What used to motivate you now seems pointless.
- Irritability and cynicism toward colleagues, clients, or patients. You notice that you think about the people you work with in increasingly cold or sarcastic terms.
- Avoidance behavior. You procrastinate on tasks, avoid meetings, and "disappear" from communication.
- Withdrawal from loved ones. After returning home, you lack the energy to interact and withdraw from family and friends.
Reduced efficacy
- Concentration and memory difficulties. You read the same sentence multiple times or forget agreements.
- Declining work productivity. Tasks that used to take an hour now take half a day.
- Doubts about your competence. A feeling that you can no longer cope, even though your qualifications haven't objectively changed.
- Difficulty making decisions. Even small choices cause tension or seem insurmountable.
How does burnout differ from normal fatigue?
The essential difference is recovery. Normal fatigue passes after resting: you return with energy after a weekend off or a vacation. In the case of burnout, rest helps only briefly or not at all because the problem is not a lack of strength, but a chronic mismatch between demands and resources. The second difference is duration: we talk about burnout when symptoms persist for weeks and months, not just a few days.
How many people experience burnout?
International data shows that the problem is widespread. According to Gallup's 2024 global workplace study, 41 percent of employees report experiencing a lot of stress daily. Newer 2025 research indicates that about 43 percent of workers worldwide feel burned out. The situation in Lithuania is also worrying: an international study conducted by scientists at Vilnius University showed that the burnout risk for Lithuanian employees is among the highest in the world, and among healthcare workers, signs of burnout were found in as many as 74 percent of those studied.
When to seek help?
If you recognize 4 or more of the listed signs and they persist for more than a month, it is worth consulting a psychologist or psychotherapist. Seek help urgently if you notice signs of depression: a persistent low mood in all areas of life, feelings of worthlessness, or thoughts of suicide. Burnout and depression can overlap, and distinguishing between them is the job of a specialist.
Frequently asked questions
Is burnout a diagnosis? No. In ICD-11, burnout (QD85) is classified as an occupational phenomenon, not a disease. However, its consequences, such as depression or anxiety disorders, are diagnosable and treatable conditions.
Can you burn out outside of work? The WHO definition applies only to the occupational context, but researchers also study parental burnout and burnout while caring for loved ones. The mechanism is similar: a chronic mismatch between demands and resources.
Is there a test to determine burnout? The most commonly used tool is the Maslach Burnout Inventory (MBI), created by Christina Maslach and Susan Jackson in 1981. Self-diagnosis tests online can help assess risk but do not replace a specialist's evaluation.
How long does it take to recover from burnout? It depends on the severity: from a few weeks to a year or longer. Read more about this in the article "How long does it take to recover from burnout?".
Can burnout be caused not only by the amount of work, but also by its nature? Yes. Burnout researcher Christina Maslach identifies six risk areas: workload, lack of control, insufficient reward, breakdown of community, absence of fairness, and value conflict. A person can burn out even when working few hours if the work constantly contradicts their values or lacks autonomy and recognition. Therefore, when assessing risk, it is important to look not only at the hours but also at the quality of the work.
