Signs of burnout: what the WHO definition says, and what the numbers show
Burnout is not just being tired. The World Health Organization defines it precisely, and recent survey data show women report it more often than men.
This article is general information, not medical advice. If you think you need care, contact a health professional.
The official definition
In 2019 the World Health Organization included burn-out in the eleventh revision of its International Classification of Diseases (ICD-11), which came into effect on 1 January 2022. It is listed as an occupational phenomenon, not as a medical condition, and described as a syndrome resulting from chronic workplace stress that has not been successfully managed.
The WHO describes three dimensions:
- Exhaustion – feelings of energy depletion or exhaustion;
- Mental distance – increased distance from one's job, or feelings of negativism or cynicism about it;
- Reduced professional efficacy – the sense that you no longer do your job well.
The definition is deliberately narrow: it refers to the work context and, according to the WHO, should not be used to describe experiences in other areas of life.
How common is it?
Gallup asks US employees how often they feel burned out at work. In its fourth-quarter 2025 data, published in March 2026, 31% of women working full time said they feel burned out "very often" or "always", against 23% of men.

The gap persists higher up. Averaging 2022 to 2025, Gallup found 29% of women in leadership roles reported burnout, compared with 19% of men in those roles; among managers the figures were 34% and 27%.
Signs to look for, by dimension
| Dimension | What it can look like day to day |
|---|---|
| Exhaustion | Waking up tired after a full night; a weekend no longer resets you; dreading Sunday evening. |
| Mental distance | Irritation at colleagues or clients you used to like; "doing the minimum"; joking darkly about work all the time. |
| Reduced efficacy | Tasks you once found easy take twice as long; small mistakes pile up; feeling that nothing you do makes a difference. |
One sign alone on a bad week is normal. A pattern that lasts weeks, across all three columns, is what the definition describes.
Burnout or something else?
Because the WHO ties burnout to work, a low mood that follows you everywhere – loss of interest in things you enjoy outside work, changes in sleep or appetite, hopelessness – deserves a conversation with a doctor rather than a self-diagnosis. In the US, the 988 Suicide & Crisis Lifeline can be reached by calling or texting 988 at any time.
What helps
- Name the cause, not just the feeling. The definition points at unmanaged workplace stress: workload, unclear expectations, lack of control. Write down which ones apply before talking to a manager.
- Ask for one concrete change. A deadline moved, a task handed over, a meeting dropped. Specific requests are easier to grant than "I'm overwhelmed".
- Protect recovery time. Exhaustion is the first dimension: sleep, time off and evenings without email are treatment, not luxury.
- Use what exists. Many employers offer an employee assistance programme (EAP) with free, confidential counselling sessions.
