Mental Health at Work: How to Set Healthy Boundaries
Have you ever reached the end of a work day completely exhausted, with no energy to do anything you enjoy, feeling like work has taken over every hour of your life? If this situation sounds familiar, know that you are not alone. In 2026, with the hybrid model and remote work increasingly consolidated, the line between professional life and personal life has become even thinner — and the impacts on mental health are real and deserve attention.
The World Health Organization (WHO) recognizes the work environment as a space that can both promote well-being and pose a risk to mental health. Professional exhaustion — internationally known as burnout — was included in the International Classification of Diseases (ICD-11) as an occupational phenomenon, which reinforces the seriousness of the topic. Creating healthy boundaries at work is not frivolous or a lack of commitment: it is a legitimate necessity and a form of self-care.
This article was written to help you understand what these boundaries are, why they matter, and how to start building them in your daily life. Always remember: each person has a different story, and for individual mental health issues, monitoring by a qualified professional is irreplaceable.
What are healthy boundaries at work?
Healthy boundaries are agreements — often implicit — that you establish with other people and with yourself about what is acceptable in your professional routine. They define where your time, energy, and availability end, without needing to give up who you are outside of work.
In practice, a boundary can manifest itself in different ways:
- Not responding to work messages after a certain time
- Taking lunch break without checking emails
- Saying “no” to demands that exceed your actual capacity
- Reserving time for personal activities without guilt
- Clearly communicating when a task doesn’t fit in your schedule
It is important to understand that setting boundaries does not mean being inflexible or uncooperative. It means respecting your own well-being so you can contribute in a sustainable — and often more creative and productive — way in the long term.
Why is it so hard to say no?
If creating boundaries seems simple in theory, why do so many people struggle with it in practice? The answer involves cultural, psychological, and structural factors.
In many cultures, including Brazilian culture, there is a historical valorization of effort above all else — the idea that “whoever works more, is worth more.” This creates an environment where asking for boundaries can be interpreted as weakness or lack of interest. Moreover, the fear of judgment, of losing opportunities, or of displeasing colleagues and leaders often inhibits necessary conversations.
There is also a psychological dimension: many people associate their identity and self-esteem with professional performance. When work becomes the main source of personal value, any boundary seems like a threat to one’s very identity.

Signs that your boundaries may be compromised
Recognizing when something is not right is the first step. Some signs that usually indicate that boundaries at work need attention:
- Constant sense of tiredness that doesn’t go away even after rest
- Difficulty “switching off” from work during leisure time
- Irritability or impatience with loved ones
- Difficulty concentrating and frequent forgetfulness
- Feeling guilty when not working
- Gradual abandonment of hobbies, friendships, and pleasurable activities
- Frequent physical pain with no identified cause (such as headaches or muscle tension)
These signs are not diagnoses, but invitations to pay attention. If you identify with several of them persistently, it’s worth considering talking to a health professional. To understand more about how stress manifests in everyday life, see: Stress in everyday life: signs and ways to cope.
How to start creating boundaries in practice
Creating boundaries is a gradual process, not a flip of a switch. Some strategies that usually help:
1. Know your own boundaries before communicating them
Before saying anything to colleagues or managers, it’s helpful to understand internally what you need. Ask yourself: which situations leave me most overloaded? At what times do I feel most exhausted? What would I like to protect in my routine?
2. Start with small, concrete changes
There’s no need to reorganize everything at once. Choose one habit to implement, like not checking work messages after 7 PM, or reserving lunch time to step away from the screen. Small, sustainable changes usually have more impact than major transformations that don’t last.
3. Practice direct and respectful communication
Saying no doesn’t have to be aggressive. Phrases like “I can’t take this on right now, but can we think of another solution?” or “I need to organize my schedule before confirming” are ways to communicate boundaries with respect and clarity.
4. Use routine resources to your advantage
Beginning and end-of-work rituals help your brain differentiate “work time” from “personal time.” This can be as simple as a quick stretch when you close your computer, a short walk, or a cup of tea that marks the transition.
5. Quick weekly review
Reserve a few minutes each week to evaluate: how was my week? Did I respect the boundaries I set? What worked? What needed adjustment? This reflective practice usually helps boundaries become a natural part of your routine, not a rigid list of rules.
6. Observe technology use
In hybrid and remote models, technology can make work “invade” all spaces in your home and free time. Disabling notifications outside work hours, creating separate folders for professional and personal emails, or using distinct profiles on your phone are simple resources that can help. Excessive screen use can also affect sleep — something worth considering.
The role of the work environment
Creating boundaries doesn’t depend solely on the individual. The organizational environment plays a fundamental role. Companies that promote a culture of respect for employees’ time, that communicate clear expectations, and that have leaders who set an example tend to have healthier and more engaged teams.
If you hold a leadership position, know that your behavior directly influences your team’s perception of safety to establish their own boundaries. Sending messages outside of work hours, even without expectation of immediate response, usually creates implicit pressure.
For those in a collaborator position who feel the environment is structurally harmful, it may be harder to act alone — and seeking outside support, whether from a mental health professional or trusted people, can be an important path.
When to seek a health professional
Some signs indicate it’s time to seek professional support without delay:
- Symptoms of intense exhaustion that persist for weeks, even with care attempts
- Frequent feelings of hopelessness, worthlessness, or emptiness related to work
- Significant changes in sleep, appetite, or mood
- Difficulty performing simple daily tasks
- Disturbing thoughts you can’t control
- Using alcohol or other substances as a way to cope with stress
Psychologists and psychiatrists are the most indicated professionals for mental health issues. Family doctors and general practitioners can also be a first point of contact. Remember: asking for help is a sign of self-care and strength, not weakness.
If you are experiencing intense suffering or a crisis, the CVV (Center for Life Enhancement) operates 24 hours at 188, with free calls. In emergencies, seek the nearest urgent care facility or emergency room.
Conclusion
Creating healthy boundaries at work is a continuous exercise of self-knowledge, communication, and self-respect. It doesn’t happen overnight, and each person will find their own way to build this balance — respecting their reality, their history, and their resources.
Most importantly is to start paying attention: to your own signs, your own needs, and the small steps within your reach. Taking care of mental health is not a luxury — it is an essential part of a life with quality and meaning.
