Burnout and Microstressors: How Small Daily Stress Leads to Big Exhaustion

Do you think burnout only happens to people facing major trauma or working high-pressure jobs like CEOs or surgeons? That’s what I used to believe, too. I’d feel guilty for struggling, after all, I had a “normal” busy life like everyone else. Why couldn’t I just handle it better?

Turns out, burnout isn’t always about the big stuff. It’s often the small, relentless stressors or microstressors, that quietly pile up until they tip the scales. And, working women are prime candidates as the more time poor and under resourced we are the more we will suffer, with working mums typically being the most affected. Sound familiar?

What Are Microstressors?

Microstressors are tiny, often overlooked moments of tension that chip away at your emotional and mental reserves. Research shows that burnout is more commonly caused by the accumulation of these small stressors than by one single event.

Interestingly, the concept of microstressors emerged by accident. Researchers were interviewing high-performing employees—300 people across 30 global organisations—to understand what made them effective collaborators. They found many were struggling with work-life balance, feeling like they were barely holding it together. The cause? Not one identifiable stressor, but the cumulative effect of everyday life.

From these interviews the researchers identified three main categories of microstressors.

Stressors that drain your personal capacity

Stressors that drain your personal capacity include uncertainty about others' reliability, unpredictable behavior from someone in authority, or sudden increases in responsibility at work or home.

Stressors that deplete your emotional reserves

Stressors that deplete your emotional reserves include managing and feeling responsible for the success and well-being of others, confrontational conversations, lack of trust in your network, or dealing with people who spread stress.

Stressors that challenge your identity and values

Stressors that challenge your identity or values, such as pressure to pursue goals that don't align with your personal values, attacks on self-worth or confidence, or draining or negative interactions with family and friends.

Apparently most of us are experiencing several of these microstressors on a daily basis.

Why Microstressors Are Increasing

The rise in the use of technology and the blurring of home/work boundaries has increased the number of microstressors we are exposed to. Many of us are waking every morning to a loud alarm when our bodies need at least another hours sleep, then checking our phones before we even get out of bed.

Working women often face more microstressors due to the dual demands of career and home life. Balancing work responsibilities, household tasks, childcare, and social expectations creates a constant stream of small stressors that accumulate over time. These microstressors, ranging from managing conflicting schedules to handling emotional labor, can quietly drain energy and increase the risk of burnout, making it essential for working women to adopt strategies for managing both internal and external stress.

How Microstressors Tip the Burnout Scales

Imagine a set of scales with microstressors on one side and your resilience and ability to manage those stressors on the other. Most of the time you have the strength and mental wellness to manage what life throws at you so the scales remain balanced or even tip in favor of wellness. However, over time the microstressors can get too much, tipping the scales in the other direction, resulting in burnout.

To protect your wellbeing you need to manage the number of microstressors you are exposed to and the effects they have on you.

How Microstressors Affect Others

Microstressors don't just effect you, they can ripple outward. For example, a colleague misses a deadline, so you commit to spending your Sunday completing it. This puts you in a bad mood so you over react when the supermarket tills are not working, making the shop assistant’s job harder. When you return home and tell your partner they have to take both children to their activities, they have to cancel their gym class, putting them in a bad mood. You then feel guilty about how you reacted at the supermarket, that you have to work on Sunday, and that your partner can’t go to their gym class, and so on and so on.

So not only do you have to be aware of your own microstressors we need to learn how to manage them so we don’t increase microstressors for those around us.

How to Manage Your Microstressors

Internal vs external microstressors

For me , I found it helpful to separate out the internal and external microstressors.

• Internal microstressors: Thoughts you generate, like self-criticism or nagging reminders. You control whether to engage with them.

• External microstressors: Real-life events or people. You can’t always control them, but you can manage your exposure and reactions.

Internal micro stressors are created by you, this means you have complete control over whether to let them breathe or not. This was a revelation to me, if I was creating many of my microstressors myself then I had the power to remove some of them.

External microstressors is a little harder because these are real people and real responsibilities, but you can still make progress. Remember the scales I mentioned previously, this is a numbers game so just removing a few microstressors can make all the difference.

Tools and strategies

The first step is to identify all of your microstressors. This may take a few goes but find some time and just note down everything that's in your brain. What are you worried about? What is keeping you up? You won't be able to remove all of these concerns but just the action of acknowledging them is going to make a difference.

The next step is to separate out the internal microstressors from the external ones, as your treatment is going to vary.

Tools for internal microstressors

For internal stressors I use an exercise I found in a brilliant book called Unstressable, I have a direct conversation with my brain. The conversation goes something like:

Me: "Brain what is wrong why are you feeling so stressed?"

Brain: “ The house is a mess”

Me: "yes, I know the house is a mess and I will tidy it, what else ?"

Brain: “ You need to eat more healthily”

Me: "I know I am doing my best and we will work on this more next week, what else?"

And if you keep going eventually your brain will eventually start to slow down and will even start saying some positive things. I’ll be honest I was sceptical about this at first but I find it really works and helps alleviate some of my internal microstressors.

Limiting technology stressors can also really help. Reduce or remove social media which makes you feel inadequate, insecure or drained.

Tools for external microstressors

The key to managing your external microstressors is to find ways to either delete, delegate or delay tasks. Have a real think about whether everything on your list is really your responsibility? Are there things you can give up or ask someone else to take on? Or are there things which just don't really matter?

I like to think of having a microstressors budget—what deserves to be included in your budget, and what should you let go of?

Managing technology is also recommended here. If you manage all of the WhatsApp groups or your kids school and activities, are there any you can remove? Can you ask you partner if they will share the load? Introduce strict boundaries for social media and phone use, for example switch your phone to aeroplane mode after 8 pm.

You may also have to reduce contact with some people in your life that cause you these stressors. This doesn’t have to be dramatic and can be as simple as saying no to a coffee every now and again.  There may also be some aspects of your work set up you can tweak to limit stressors such as declining a meeting or seeing if someone else can take on chairing the next committee meeting.

Keep in mind that this is a numbers game; you just need to decrease your microstressors enough to balance the scales. Try tracking your microstressors for just one week and notice the difference.

The Anti-Burnout Mindset

Managing your microstressors budget is a crucial aspect of the Anti-Burnout Mindset. Your resilience may fluctuate over time but being conscious of the need to balance those scales can be a valuable tool in managing your risk of burnout.

So next time you feel overwhelmed by “just the little things,” remember: those little things matter. And you deserve the space to breathe. Interested in finding out more? try out my Ultimate Anti-Burnout Recovery Plan for Working Women and start your burnout free life today.
