Why boundaries matter for your mental health
When you think about improving your mental health, you might picture meditation, more sleep, or exercise. Those all help, but one of the most powerful tools is often overlooked: setting boundaries at work. In fact, setting boundaries at work for mental health can protect you from burnout, constant stress, and that drained feeling that follows you home at the end of the day.
During the COVID-19 pandemic, many people saw work spill into every corner of their lives. Constant video calls, pings at all hours, and blurred lines between home and office made it hard to ever feel truly off. Researchers and wellbeing experts have since emphasized that clear boundaries are not a luxury, they are essential for your mental health and work-life balance (Well-Being at Iowa, UC Davis Health).
The good news is that you can start creating healthier limits even if your job is demanding or fast paced.
Recognize signs you need better boundaries
Before you change anything, it helps to notice how your current habits affect you. You may need stronger boundaries if you:
- Check work email late at night or first thing in the morning without thinking
- Say yes to new tasks even when your plate is already full
- Feel guilty when you are not available to coworkers
- Have trouble focusing because of constant interruptions
- Think about work long after your workday is supposed to be over
Research has found that people who maintain clear lines between work and personal life are less likely to ruminate about work after hours, which protects their mental health (HALO Psychology). When you do not have those lines, stress and exhaustion build up over time.
Understand how poor boundaries drain you
It is not just that overworking feels tiring. There are real mental and physical effects when you rarely say no or when work intrudes on every part of your day.
Constant interruptions increase stress
If you cannot get through a task without being pinged, called, or tapped on the shoulder, your brain never gets to fully focus. One study cited by HALO Psychology found that employees spend about 11 minutes on a task before an interruption and need about 25 minutes to refocus afterward (HALO Psychology). Those frequent breaks in concentration can raise cortisol, your main stress hormone, and make it harder to think clearly.
Always saying yes breeds burnout
When you put everyone else’s needs first at work, you may start to feel overlooked or unappreciated. Over time, taking on too much and ignoring your own limits can lead to burnout and emotional exhaustion (Workplace Strategies for Mental Health). You might notice:
- Irritability or impatience
- Trouble sleeping
- Headaches or tension
- A sense of dread before work
These are not just signs that you are busy. They are signals that your boundaries might be too loose.
Blurred lines erase work-life balance
During the pandemic, many people went from one video meeting to the next without breaks, then tried to squeeze in personal tasks late at night. Leaders who later reflected on this period saw how that pattern hurt their own mental health and workplace culture (Well-Being at Iowa). Without boundaries, recovery time shrinks and your brain never gets the reset it needs.
Learn the types of boundaries you can set
When you think about setting boundaries at work, you might picture a firm “no.” That is part of it, but you actually have several types of limits you can use to protect your mental health.
Hard vs soft boundaries
The Canada Life Workplace Strategies for Mental Health resource describes two useful categories (Workplace Strategies for Mental Health):
- Hard boundaries. Non negotiable lines you set to protect your health or rights.
- Example: “I am not able to work overtime because of my health.”
- Soft boundaries. Flexible guidelines that still protect your time and energy.
- Example: “I answer emails between 9 a.m. and 5 p.m. If you contact me after that, I will respond the next business day.”
Hard boundaries help you stay aligned with your values and needs. Soft boundaries give you structure without being rigid.
Areas where boundaries help
You can create boundaries in several areas of your work life:
- Time boundaries
- Work hours, meeting limits, response times
- Task boundaries
- What work is truly your responsibility, how much you can realistically take on
- Communication boundaries
- How coworkers contact you, when you are available, how quickly you reply
- Emotional boundaries
- How much you absorb others’ stress, how personally you take criticism
- Physical and environmental boundaries
- Protecting your breaks, using quiet time, logging off devices after work
Each of these supports your mental health in a slightly different way. Together they create a clearer, calmer workday.
Follow a simple process to set boundaries
If you are not used to advocating for yourself, setting boundaries at work can feel uncomfortable. A clear step by step approach can make it easier. Workplace Strategies for Mental Health suggests a seven step process you can adapt (Workplace Strategies for Mental Health).
1. Write your boundary down
Start by getting specific on paper. Ask yourself:
- What exactly is draining you?
- What would feel better instead?
For example:
- “I will not schedule back to back video meetings without at least a 15 minute break.”
- “I will not answer emails after 6 p.m. on weekdays.”
Writing your boundary helps you clarify it and makes it easier to communicate later.
2. Check that it respects others’ rights
Healthy boundaries do not trample someone else’s rights or put coworkers in a difficult position. Before you share a boundary, look at it from other angles:
- Does this violate my employment agreement or job description?
- Will this unfairly shift my workload to someone else?
If needed, adjust the wording. Instead of “I will never work late,” you might say “I can occasionally work late for urgent issues, but not as a regular expectation.”
3. Decide where you draw the line
Now make your boundary concrete. You might:
- Set a clear time, such as “no calls after 5:30 p.m.”
- Limit quantity, such as “no more than four meetings per day.”
- Define scope, such as “I can help with editing this report, but I cannot own the whole project.”
Specific lines make it easier for others to understand what you can and cannot do.
4. Plan what you will do if it is crossed
Decide ahead of time how you will respond if someone pushes past your boundary. This is not about punishment. It is about protecting your mental health. For example:
- If a coworker keeps sending non urgent messages at night, you will wait to reply until morning.
- If new tasks are added to your plate, you will ask your manager which existing task should be deprioritized.
Knowing your next step helps you stay calm instead of reacting in the moment.
5. Communicate your boundary clearly and calmly
Clear communication reduces ambiguity, which your brain tends to see as a threat. Even if people do not love your answer, being clear can actually lower stress for everyone involved (HALO Psychology).
You can use simple, respectful language such as:
- “To stay focused and meet deadlines, I keep my mornings meeting free. I can meet after 1 p.m.”
- “These are my working hours, so you can expect a reply from me between 8 a.m. and 4 p.m.”
UC Davis Health suggests including your working hours in your email signature as a subtle but effective way to set expectations (UC Davis Health).
6. Respect your own boundary
Once you have set a boundary, you teach others how seriously to take it by how you act. If you say you do not answer emails after 6 p.m. but continue replying at 10 p.m., the boundary weakens.
Try to:
- Stick to your stated work hours as closely as your job allows
- Protect your breaks, even when you feel busy
- Follow through on your planned responses when lines are crossed
Think of it as practicing a new habit rather than being perfect from day one.
7. Review and adjust over time
Work and life change, so your boundaries can change too. You might loosen some, tighten others, or create new ones as your role shifts. Periodically ask yourself:
- What is working well?
- Where do I still feel drained or resentful?
- What boundary might help with that?
This flexible mindset helps your boundaries stay realistic and sustainable.
Use practical examples that support your mental health
It helps to see what boundaries look like in real life. Here are some ideas you can tailor to your situation.
Time and schedule boundaries
- Meeting breaks. During the pandemic, some people found that taking at least 15 minutes between video calls dramatically improved their mental and physical health (Well-Being at Iowa). You might block your calendar with short breaks to prevent back to back meetings.
- Defined workday. Put your working hours in your email signature, then actually log off at that time whenever possible (UC Davis Health).
- Focus time. Reserve a few hours each day for deep work. Silence notifications and let your team know that you will be slower to respond during that window.
Workload and task boundaries
- Clarify priorities with your manager. UC Davis Health recommends setting expectations around what tasks come first. If you are asked to take on something new, you can say, “I am happy to help. Which of my current priorities should I pause or delay?” (UC Davis Health)
- Use a tool to sort tasks. The Eisenhower Grid, which separates urgent from important, can help you push back on requests that do not fit your top priorities (HALO Psychology).
- Limit “yes” habits. When you want to say no but feel pressured, remember that saying no to one request is often saying yes to your own well being or to the quality of your existing work (UC Davis Health).
Communication and availability boundaries
- Response windows. Decide when you will check email or messaging apps and when you will not. Let your team know, for example, “I check messages every hour, so if something is urgent, please call.”
- Alternative channels. During remote work, some leaders improved their mental health by limiting video calls and using phone or email instead when possible (Well-Being at Iowa). You can suggest a phone call instead of yet another video meeting if that feels more manageable.
- Escalation rules. Create simple guidelines like, “If it is urgent and I am not online, please text or call. Otherwise, I will respond in my next work block.”
Emotional and self-care boundaries
- Separate others’ stress from your own. You can be supportive without absorbing everyone’s emotions. If a coworker vents frequently, you might say, “I want to support you, but I only have 10 minutes right now. After that I need to get back to my work so I do not fall behind.”
- Protect recovery time. Plan screen free breaks during the day to move your body, step outside, or simply breathe. Mindfulness and brief grounding practices during the workday have been shown to support mental health and a more positive work environment (Well-Being at Iowa).
- Seek support when you need it. Some workplaces, like Vanderbilt University with its partnership with Lyra, offer counseling or coaching sessions to help employees navigate boundaries and mental health challenges (Vanderbilt University). Check what resources your employer provides.
Remember that boundaries help your workplace too
It can be tempting to think that boundaries are selfish or unhelpful to your team. In reality, they support both you and your workplace.
Vanderbilt University highlights that setting boundaries at work protects employee well being and prevents burnout, which in turn improves retention, satisfaction, morale, and teamwork (Vanderbilt University). For leaders, modeling boundaries shows your team that it is acceptable to care for their own mental health. That kind of culture aligns with broader efforts, like the U.S. Surgeon General’s focus on workplace mental health and well being.
When you set clear limits, you:
- Reduce confusion about when and how you can help
- Deliver better quality work because you are less scattered
- Model healthy behavior for colleagues who might be struggling
Everyone benefits when people are not constantly running on empty.
Take a small step today
You do not have to overhaul your entire work life at once. To start using setting boundaries at work for mental health, choose one simple action you can try today. For example, you might:
- Add your working hours to your email signature
- Block a 15 minute break between two long meetings
- Use one polite “no” or “not right now” instead of automatically saying yes
Notice how even a small shift affects your stress level and energy. Over time, these small, consistent choices add up to clearer boundaries, better balance, and less mental exhaustion.
Your needs matter. Honoring them at work is not a weakness, it is a key part of protecting your mental health and bringing your best self to both your job and your life outside it.
