You wake up exhausted even after a full night’s sleep. Sunday afternoons become a minefield of anxiety just thinking about the next day. Small work tasks seem like insurmountable mountains. If any of these scenarios sound familiar, know that you’re not alone — and these could be signs that your mental health in the workplace deserves urgent attention.
The world of work has changed profoundly in recent decades. Accelerated digitalization, the “always available” culture, remote work, and the pressure for constant productivity have created an environment where psychological illness has become one of the main causes of professional leave worldwide. According to data from the World Health Organization (WHO), disorders such as depression and anxiety cost the global economy trillions of dollars per year in lost productivity — an impact that goes far beyond individual suffering.
The good news is that recognizing early signs and knowing how to act makes all the difference. This article provides general information about the main warning signs of mental illness at work and a practical guide on how to take care of yourself and contribute to healthier environments. Remember: each case is unique, and individual situations should always be evaluated by a qualified health professional.
What is mental health at work — and why it matters so much
Mental health at work is not just the absence of diagnosed illnesses. The WHO defines mental health as a state of well-being in which individuals can cope with normal life stresses, work productively, and contribute to their community. Applied to the professional environment, this means being able to perform your duties without work chronically compromising your emotional balance.
The problem is that, historically, psychological suffering at work has been treated as individual weakness or lack of resilience. This view is gradually being overcome — but stigma still exists in many environments. Recognizing that work can make people sick is not pessimism; it’s responsibility.
Companies that invest in psychologically healthy environments generally experience lower turnover, fewer days of absence, and greater team engagement. In other words, caring for workers’ mental health is both a human and strategic matter.
Main warning signs: when work is making you sick
Identifying early signs is the first step to taking action before the situation worsens. They can appear in physical, emotional, and behavioral forms — and often emerge subtly, becoming part of a routine that seems “normal,” but isn’t.
Physical signs
- Extreme fatigue that doesn’t improve with rest
- Frequent headaches with no identified organic cause
- Sleep disturbances (insomnia or excessive sleeping)
- Recurrent gastrointestinal problems linked to stressful moments
- Decreased immunity, with frequent infections
Emotional signs
- Persistent feelings of emptiness, sadness, or irritability
- Elevated anxiety before or during work hours
- Difficulty concentrating and memory lapses
- Feeling that your effort is never enough
- Loss of satisfaction in activities that were previously enjoyable, including outside of work
Behavioral signs
- Social isolation in the workplace and personal life
- Visible drop in productivity and increased errors
- Intense procrastination and difficulty making simple decisions
- Increased use of alcohol, caffeine, or other stimulants to “get through” the day
- Absenteeism (frequent absences) or, at the opposite extreme, presenteeism (going to work even when sick, out of fear of consequences)
Burnout: the exhaustion that became an official diagnosis
One of the most discussed phenomena in recent years is burnout. In 2019, the WHO included burnout in the International Classification of Diseases (ICD-11), which came into effect in 2022, defining it as a syndrome resulting from chronic workplace stress that has not been successfully managed.
Burnout manifests in three main dimensions:
- Exhaustion: feeling of total depletion of energy, emotional and physical
- Mental distancing from work: cynicism, indifference, or negative feelings toward professional activities
- Reduced efficacy: feelings of incompetence and lack of accomplishments, even when objective performance hasn’t dropped significantly
It’s important to be clear: burnout is not weakness, laziness, or character flaw. It’s a medically recognized condition with real impact on physical and mental health. Any suspicion of burnout should be investigated by a doctor or psychologist.
Risk factors in the workplace
Not all stress is harmful — a moderate level of pressure can even stimulate performance. The problem arises when risk factors accumulate without support or recovery. Among the main organizational triggers identified by occupational health literature are:
- Excessive workload and chronically unrealistic deadlines
- Lack of autonomy: little control over how and when tasks are performed
- Role ambiguity: not knowing exactly what is expected of you
- Toxic organizational climate: gossip, excessive rivalry, lack of recognition
- Moral or sexual harassment, whether by managers or colleagues
- Job insecurity: constant fear of dismissal or not meeting goals
- Lack of work-life balance, especially common in remote work
What you can do: practical guide
This section is informative and does not replace professional guidance. Consider it a starting point for reflection and action.
- Recognize and name what you’re feeling. It seems simple, but many people spend months or years minimizing their suffering. Accepting that something is wrong is the first step to change.
- Seek professional support. A psychologist or psychiatrist is the most qualified professional to assess your emotional state and indicate appropriate treatment. In Brazil, the Unified Health System (SUS) offers mental health care through Psychosocial Care Centers (CAPS) and Basic Health Units (UBS).
- Talk to someone you trust. You don’t have to face this alone. A friend, family member, or mentor can help put things in perspective.
- Establish clear boundaries. Learn to say no when necessary, disconnect outside of work hours, and respect your own rest periods.
- Take care of health fundamentals. Quality sleep, balanced nutrition, regular physical activity, and leisure time are not luxuries — they’re pillars of mental balance.
- Evaluate your relationship with work. Ask yourself honestly: is the environment itself toxic? Is there something structural that needs to change? Sometimes the solution involves difficult conversations with managers or, in extreme cases, changing companies or careers.
- Know your rights. In Brazil, labor legislation provides protocols for cases of harassment and occupational illness. Leave for work-related mental disorders may be covered by INSS, depending on the situation. Consult a legal professional if necessary.
The role of companies and managers
Responsibility for mental health at work does not rest solely on the individual. Organizations and leaders play a fundamental role in creating — or destroying — psychologically safe environments.
Psychologically safe environments are those where employees feel comfortable expressing ideas, asking questions, admitting mistakes, and asking for help without fear of punishment or humiliation. The concept was extensively studied by Harvard Business School researcher Amy Edmondson and is considered one of the main factors of high-performance teams.
Some practices companies can adopt include:
- Offering psychological support programs (such as EAP — Employee Assistance Programs)
- Training managers to identify signs of suffering in teams
- Creating safe and confidential channels for harassment reports
- Regularly reviewing goals and workloads
- Normalizing conversations about mental health in the corporate environment
In 2025, the update of Regulatory Standard No. 1 (NR-1) by Brazil’s Ministry of Labor and Employment began requiring companies to include psychosocial risks in occupational risk management — a significant regulatory advance that reinforces organizational responsibility in this field.
Conclusion: caring for the mind is as urgent as caring for the body
Mental health at work has moved from a niche topic to become one of the central issues of the contemporary professional world. Recognizing warning signs — in yourself and colleagues —, seeking help without shame, and demanding healthier environments are attitudes that make a real difference in people’s lives.
If you identified some of the signs described in this article, don’t ignore them. Seek a health professional, talk to someone you trust, and take the first step. Getting sick is not inevitable — and recovery is possible.
And if you’re in a leadership position, remember: a mentally healthy team is not just more productive. It is, above all, more human.
