The word “burnout” has entered everyday language, to the point where it can describe anything from a hard week to a lasting collapse. Such casual use blurs what we actually know. Here is what health institutions and research have established, and the questions specialists are still debating.
In brief
- For the WHO, burnout is an occupational phenomenon rather than a mental illness.
- It combines exhaustion, mental distance from one’s job and reduced professional efficacy.
- Low control over one’s work and lack of support are the best-established factors.
- Its boundary with depression is debated; a doctor should look for an associated depression or anxiety disorder.
- Care combines appropriate sick leave, psychological support and a well-prepared return to work; actions on how work is organised appear the most effective, with modest effects overall.
1. Where does the concept come from?
The term was popularised in 1974 by the American psychologist Herbert Freudenberger, who observed the gradual exhaustion of highly committed volunteers at a free clinic in New York (Freudenberger, 1974). A few years later, the psychologist Christina Maslach proposed a definition and a measurement questionnaire, the Maslach Burnout Inventory, which remains the reference tool in research (Maslach and Jackson, 1981).
2. An occupational phenomenon, rather than a mental illness
Since 2019, the WHO’s International Classification of Diseases (ICD-11) has described burnout as “a syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed” (WHO, 2019). It is listed among the factors influencing health status, outside the chapter on mental disorders. The WHO characterises it by three dimensions, which follow Maslach’s model:
| Dimension | What the person experiences |
|---|---|
| Exhaustion | A deep physical and emotional fatigue that rest no longer repairs. |
| Mental distance or cynicism | Detachment, irritability or a negative view of one’s job and of the people involved. |
| Reduced efficacy | The feeling of no longer being up to the task, of doing less well, of no longer achieving anything. |
The WHO specifies that the term refers specifically to the occupational context. It is meant to be reserved for work rather than used to describe exhaustion experienced in other areas of life, for example among parents (Mikolajczak et al., 2019) or carers, even though comparable forms of exhaustion exist there too.
3. What sustains it: the way work is organised
Burnout is explained first and foremost by working conditions, far more than by personality. A systematic review of 25 prospective studies examined the working conditions associated with emotional exhaustion (Aronsson et al., 2017). Two factors stand out with a moderate level of evidence: low control over one’s work and lack of support in the workplace. Other factors are associated with it on more limited evidence: high workload, emotional demands, insufficient recognition and job insecurity. Conversely, a sense of fairness at work is associated with less exhaustion.
Maslach and Leiter summarise these findings as six areas in which a lasting mismatch can develop between a person and their job (Maslach and Leiter, 2016):
- Workload: too much work, for too long, without recovery.
- Control: little room for manoeuvre over how the work is done.
- Reward: efforts that go largely unseen and unvalued.
- Community: a working community that has deteriorated or is absent.
- Fairness: a sense of injustice in decisions.
- Values: having to do things that run counter to what matters to you.
Highly committed, conscientious or perfectionist people are often described as more exposed. Yet it is the encounter between that commitment and an organisation that drains a person’s resources that produces burnout.
4. A health issue that goes beyond fatigue
A review of 36 prospective studies followed the consequences of burnout over time (Salvagioni et al., 2017). Burnout emerged as a predictor of physical conditions: type 2 diabetes, coronary heart disease, musculoskeletal pain and sleep disorders. It also predicted depressive symptoms, increased use of psychotropic medication, absenteeism and disability pensions. These associations do not in themselves prove cause and effect, and some findings are contradictory. They do, however, justify taking persistent warning signs seriously.
5. Burnout or depression: an open debate
This is the question researchers discuss most, and the data do not all point the same way. A meta-analysis of 69 studies covering more than 84,000 people found a clear but partial correlation between burnout and depression (r = 0.52): its authors conclude that these are two distinct realities that overlap while remaining separate (Koutsimani et al., 2019). Conversely, a study of 1,386 American teachers found that 86% of those with burnout met provisional criteria for depression, and its authors see a considerable overlap (Schonfeld and Bianchi, 2016).
For clinical practice, the French National Authority for Health (Haute Autorité de santé, HAS) settles what needs settling: the doctor should look for depression, an anxiety disorder or post-traumatic stress disorder, and check whether they coexist with burnout (HAS, 2017). Treatment depends on it.
6. What the French National Authority for Health recommends
In 2017, the HAS published recommendations on identifying and managing occupational burnout syndrome in France; the section on returning to work was updated in October 2025 (HAS, 2017; Santé mentale, 2025).
The main principles
- Sick leave, with a duration adapted to how the condition evolves and to the work context.
- Antidepressants only when indicated: medication is justified only if burnout is accompanied by an anxiety or depressive disorder.
- Psychotherapeutic support, combining several approaches: cognitive behavioural therapies, relaxation, mindfulness meditation.
- A well-prepared return to work, with one or more pre-return visits to the occupational physician, who may recommend adjustments to the job or even redeployment.
- Coordinated follow-up between the GP, the occupational physician and, if needed, a psychiatrist.
Rest alone, therefore, does not resolve the situation. If the conditions that led to exhaustion remain the same, returning to work exposes the person to the same pressures again.
7. Prevention: acting on the individual and on the organisation
Preventive interventions have mainly been studied in doctors. One meta-analysis showed that both individual actions (stress management, mindfulness, discussion groups) and organisational actions (changes to schedules, workload and team functioning) reduce burnout, with modest effects (West et al., 2016). Another found larger effects for interventions targeting the organisation of work than for those focused solely on the individual (Panagioti et al., 2017).
In other words, learning to manage stress better helps, and it works best when things also change around you. Preventing burnout is also the employer’s responsibility.
Take the example of Nathalie, 46, a nurse on a medical ward (a fictional case, built from common clinical situations). For months she has been working overtime in an understaffed team. She sleeps badly and becomes irritable with patients, which makes her feel guilty, and she has the impression that she is “doing her job badly”. Her doctor signs her off work, looks for an associated depression and refers her to a psychologist. Before she returns, the occupational physician arranges a pre-return visit and obtains a temporary adjustment to her rota. Without this last step, the risk of relapse would have been high.
If you are in distress
If you are having dark thoughts or thoughts of suicide, contact a crisis line: 988 (US/Canada), Samaritans 116 123 (UK and Ireland), or find a local helpline at findahelpline.com. In France, call 3114 (free, 24/7). If you are in immediate danger, call your local emergency number (999 in the UK, 911 in North America, 112 in the EU).
What is established, and what is not
- Established: burnout is an occupational phenomenon, recognised by the WHO in ICD-11, and classified among the factors influencing health status rather than as a mental disorder as such.
- Established: it is associated with real risks to physical and mental health.
- Well supported: actions on how work is organised reduce burnout at least as much as actions focused on the individual.
- Debated: the boundary between burnout and depression, which partly overlap.
Frequently asked questions
Is burnout recognised as an occupational disease?
In France, it does not appear in the official tables of occupational diseases. Recognition remains possible on a case-by-case basis, before a regional committee, when the psychological condition is severe and directly linked to work. Rules vary from country to country.
How can I tell whether I am burnt out?
The most telling signs are exhaustion that rest no longer repairs, mental distance from your work and a feeling of no longer being effective, lasting for several weeks. Only a doctor can assess the situation and look for an associated depression or anxiety disorder.
Can you burn out outside work?
In the WHO’s sense, burnout relates to work. But comparable forms of exhaustion exist elsewhere, for example among parents or carers, and they deserve the same attention.
In one sentence
Burnout arises from a lasting encounter between a committed person and a way of organising work that drains their resources.
Recognising it early, distinguishing it from depression, getting support and acting on working conditions all improve the outlook.
