Burnout, or occupational exhaustion, is a syndrome that develops over time. It emerges when work repeatedly uses more physical and psychological resources than a person can restore. Ordinary rest stops being enough, the relationship with work changes, and tasks that once felt manageable become difficult.
In Belgium, an estimated 80,000 people are affected each year. The figure covers very different experiences: an employee facing sustained overload, a self-employed person who can never switch off, a healthcare worker under continuous pressure, or a manager whose responsibilities have gradually taken over private life. Burnout can occur in every sector and at every level of seniority.
Recognising burnout symptoms makes it possible to act before a complete breakdown. The word “breakdown” is appropriate here because the foundations of the person’s life can collapse, as described by Thomas Périlleux, a sociologist and occupational clinician.
What is burnout?
The term entered the language of occupational psychology in the 1970s, when it was used to describe profound exhaustion among highly committed professionals. The image is of resources being consumed faster than they can be replenished. Research has since refined the concept and shown that burnout cannot be explained simply by an individual’s ability to cope.
The World Health Organization presents burnout as an occupational phenomenon, not a medical condition. It results from chronic workplace stress that has not been successfully managed and has three dimensions:
- feelings of depleted energy or exhaustion;
- growing mental distance from work, sometimes with negativity or cynicism;
- reduced professional efficacy.
This definition applies specifically to work. Expressions such as “parental burnout” or “student burnout” are sometimes used for other forms of exhaustion, but they do not correspond exactly to the WHO’s occupational definition.
What causes burnout?
There is rarely one cause. Burnout is more likely to develop when several pressures persist while opportunities for recovery, support and meaningful action become insufficient.
Work overload is a common factor. It is not only about hours worked. Unrealistic targets, constant interruptions, short deadlines, understaffing and accumulating responsibilities can create an endless sense of urgency. Even a capable, well-organised person can become exhausted when demands continually exceed the resources available.
A poor work–life balance also matters. Answering messages in the evening, rehearsing the next day’s problems during the night or remaining mentally connected while on leave prevents the stress response from settling. Recovery requires time and genuine psychological distance from work.
A toxic working environment may add conflict, bullying, competition, lack of support or fear of making mistakes. Limited control, unclear roles, repeated changes and little recognition can also contribute. Psychosocial risks at work concern working conditions and professional relationships, not only the way an individual manages stress.
Personal tendencies such as perfectionism, difficulty setting boundaries or very strong commitment may increase vulnerability in an unhealthy context. They should not be used to blame the person. Asking someone to become more resilient does not correct an unrealistic workload or a harmful workplace culture.
The way an organisation structures work as a whole can also be considered a cause of burnout. However, factors outside work, such as the family environment or other health conditions, may also contribute to or worsen exhaustion.
What are the symptoms of burnout?
Burnout symptoms often develop gradually. At first, the person may compensate by working longer, skipping breaks or sacrificing personal activities. They may appear to be coping even while their resources are steadily declining.
Exhaustion that does not go away
Fatigue becomes deep and persistent. Sleeping, taking a weekend off or going away for a few days no longer brings the expected relief. Some people feel empty as soon as they wake. Others function at work but have no energy left to cook, see friends or manage ordinary responsibilities.
Physical complaints may accompany exhaustion, including muscle tension, headaches, digestive problems, palpitations or increased susceptibility to illness. These symptoms do not prove burnout. A doctor can check for other explanations, such as thyroid disease, anaemia, infection, medication effects or a sleep disorder.
A deteriorating relationship with work
Someone may lose interest in their profession, become irritable or protect themselves by withdrawing emotionally. Contact with colleagues, patients or customers starts to feel burdensome. Cynicism and the belief that effort is pointless may replace earlier engagement. This distance is often an attempt to keep functioning, not evidence that the person no longer cares about doing good work.
Cognitive and emotional difficulties
Attention, concentration and working memory may be affected. Reading an email, choosing between two priorities or following a meeting requires unusual effort. Forgetfulness and mistakes increase, which creates anxiety and may lead the person to work even longer.
Emotional control may also become more fragile. Irritability, tears, heightened sensitivity, feeling overwhelmed and unusually intense reactions are common. Panic attacks can occur. Self-esteem may fall and social isolation may grow, particularly when the person interprets exhaustion as a personal failure.
Sleep problems maintain the cycle. It may be difficult to fall asleep because work continues mentally, or to stay asleep without waking to a list of tasks. Conversely, some people sleep for long periods and still do not feel restored.
Burnout or depression: how can you tell the difference?
Psychologists often point out that someone who self-diagnoses burnout may instead be experiencing another condition, such as depression.
Burnout and depression can both involve fatigue, loss of interest, cognitive difficulties, disrupted sleep and low self-worth. In burnout, problems are initially closely linked to work and may ease when the person is away from it. In depression, low mood and loss of pleasure often affect many areas of life.
The two can coexist, but burnout is generally what triggers depression. However, experiencing burnout can also be a symptom of the broader condition of depression.
Can burnout be recognised before a breakdown?
It is not possible to predict with certainty who will develop burnout, but some changes deserve attention: growing fatigue, slower recovery, disrupted sleep, impatience, unusual mistakes, feeling ineffective, withdrawing from colleagues and gradually giving up activities that previously helped.
One particularly useful warning sign is being unable to switch off. Work occupies the mind during meals, evenings and days off. People often respond by speeding up and making an even greater effort, when they actually need to slow down and receive support. Recognising this pattern early creates an opportunity to speak to a doctor, psychologist, occupational physician or trusted person at work.
How can burnout be prevented?
Prevention cannot be reduced to breathing exercises or better personal organisation. Individual habits can support recovery: real breaks, regular sleeping hours, suitable physical activity, periods without notifications and continued social contact. Learning to identify priorities and set boundaries may also help.
Lasting prevention must address work itself. Clarifying responsibilities, adjusting workloads, allowing autonomy, planning realistic staffing, training managers and acting on bullying are central measures. An early conversation may make it possible to renegotiate deadlines, redistribute tasks or protect recovery time before the situation becomes critical.
Managers and organisations should pay attention to collective signs, such as repeated absences, high staff turnover, frequent conflicts and teams that depend on constant overtime. Support should not require employees to disclose more personal information than they wish. The aim is to create conditions in which concerns can be raised safely and practical changes can follow.
How do you recover from burnout?
The first step is to seek a medical assessment. A doctor can evaluate severity, investigate other possible causes and discuss whether time away from work is necessary. Rest is often essential, but it is not always enough: returning to unchanged conditions can increase the risk of relapse.
Psychological support can help a person understand how exhaustion developed, regain stability and prepare concrete changes. Cognitive behavioural therapy (CBT) may address perfectionistic thinking, guilt, boundaries and recovery strategies.
Medication may also be prescribed in some cases to a person experiencing burnout.
Recovery is rarely linear. Energy may improve before concentration, and a good day can be followed by a difficult one. Setting a rigid deadline can add pressure. Regular review with the relevant professionals makes it possible to adjust the plan to symptoms, circumstances and the person’s preferences.
Returning to work is usually easier when it is gradual and prepared with the people involved. Adapted hours, a phased return, clear duties, a reduced workload and review points can support recovery. The right pace is individual: recovery is not about returning as quickly as possible, but about rebuilding a sustainable way of working. More broadly, it is important to restore balance and rebuild the foundations of life that support recovery from burnout. However, it should be noted that, in some cases, people may never be able to return to work.
Friends and family can help by listening without judgement and offering practical support. Advice such as “just stop thinking about work” can feel invalidating. It is often more useful to ask what the person needs today and to respect that recovery may require both rest and professional care.
