How the Mental Load Keeps Moms in Fight-or-Flight (and Why Rest Alone Won't Fix It)
The kids are in bed, the house is reset for tomorrow and you finally lay your head down after yet another exhausting day - but all you can hear is your heart beating loudly and your inner monologue of everything you need to do tomorrow, and, shoot - did you remember to start the dishwasher? You think you locked the front door. Ugh, better get up and check.
If this sounds familiar, you are not alone.
Why Read This? If you feel "wired but tired" or like you’re constantly reeling with anxiety, it isn't just busyness - it’s the Mental Load. This post explores how open "mental tabs" keep your nervous system in a state of chronic stress and why physical rest isn't enough to reset your health.
What is the Mental Load? Understanding the Invisible Labor That Never Turns Off
You’ve heard of the cognitive load and invisible labor of motherhood, and you live it every day. You track the appointments, make sure the kids have clothes that are clean (and still fit), RSVP to the birthday parties and buy the gifts, plan the meals and place the grocery order… and you’re feeling the symptoms of mom burnout. There’s a name for this heavy burden, and why you can’t relax even when you’re resting - it’s your mental load.
And here’s my hot take: Self-care, rest, and setting boundaries are not going to fix your mental burnout and chronic stress. You could sleep 10 hours tonight and still wake up exhausted tomorrow. That’s because a spa day or nap, though nice, doesn’t fix nervous system dysregulation common in moms.
The real culprit is all those “open tabs” you never close.
The Brain Science Behind Why the Mental Load Builds Up
The brain is complex and fascinating. It allows you to schedule appointments, not burn the pancakes, do the dishes, and comfort your crying (hangry) child - all at the same time. While moms often pride themselves on the ability to multitask at this level - because it is a feat - the brain actually does reach a point where it is full.
In fact, it can actually only retain 4-7 items at a time in its active working memory. When it’s working at max capacity long term, it will start to misfire. This manifests as forgetfulness, irritability, poor focus, and decision fatigue. You start to get foggy. (Does this sound familiar at all)?
To add insult to injury, unfinished tasks linger in the background like a program that you didn’t fully quit on your computer. It slows things down. Other “programs” run less effectively. This is called the Zeigarnik effect if you want to sound super cool at your next social gathering. By definition, it’s the psychological tendency to remember uncompleted or interrupted tasks better than completed ones. Your “open tabs” are pulling energy from other places and draining your battery. It is not sustainable.
How the Mental Load Raises Cortisol and Keeps Moms in Fight-or-Flight
You might be familiar with the term “fight-or-flight”- the part of your nervous system that fires when you are being chased by a bear.
As a trauma and critical care nurse, this is how many of my patients arrived to me: elevated heart rate, rapid breathing, muscles tensed, and hyper-alert (if they were conscious). This is a perfectly designed protection mechanism to help you detect and evade the bear, by giving you a surge of adrenaline.
However, your brain doesn’t know the difference between a bear or your stressful day.
This is your sympathetic nervous system (SNS) in action, but your adrenaline is just the match fueling the fire. When the match burns out, your cortisol kicks in. This is great - until it’s not.
Chronic cortisol elevation that remains activated and unchecked can make your nervous system less effective over time leading to an allostatic load that brings metabolic issues, cardiovascular disease, and immunodeficiency.
Your “rest and digest” system is meant to kick in and help you recover from the bear chase.
Unfortunately, when you’re in a state of chronic stress, this parasympathetic nervous system (PNS) becomes suppressed, keeping your cortisol flowing while eventually leading to structural changes in your brain (e.g. brain fog), chronic inflammation, pain, anxiety, and stubborn belly fat.
This is a biological response to chronic mental load burnout, and you are not napping your way out of it.
Why Self-Care Doesn’t Fix Mom Burnout, (and What’s Missing)
Before you come at me, yes, rest is essential and beneficial. Rest provides necessary recovery, aids your immune system, improves your mental clarity and productivity, and reduces stress.
Hear me: rest won’t fix the unaddressed root cause(s) of chronic stress, and therefore, will not improve the associated physical, mental, and emotional symptoms.
This is why so many moms enjoy an amazing vacation, weekend retreat, or relaxing day at the spa, and it’s all thwarted when they get home because it was just a band-aid on a larger problem.
The larger problem: the cognitive load and invisible labor was still waiting for them when they got home.
Self-care is so important, but if moms want to see long-term improvement in their quality of life, and their health, there needs to be a shift in how it’s approached.
How to Reduce the Mental Load and Reset Your Nervous System
Moms are tired of being overwhelmed and barely surviving from one day to the next. The solution isn’t more self-care and rest - it’s less mental load. So how do you decrease your mental load? You have to hand it off.
Single moms - don’t go anywhere. I have solutions for you, too, that don’t involve a nanny or disposable income.
What I Learned When Help Wasn’t Enough
In the wake of heartbreaking diagnoses for both of my young children, I suffered from a massive mental load, intense overwhelm, and crippling anxiety. There were moments I didn’t think I could survive our circumstances.
That’s when I learned that systems are the key.
We have been helped by so many people and we are grateful beyond measure, but I quickly discovered that help still pulled from my already depleted mental and emotional capacity, and trying to find ways for well-meaning people to help actually contributed to my overall mental load.
I still had to delegate the help, and I discovered if I hand off aspects of my mental load and invisible labor, someone else assumes ownership and I can wipe my hands clean of that weight.
Here are a few examples of how we did that:
We were blessed to have regular housecleaning and lawn mowing gifted to us.
A dear friend took on care coordination to fill our needs for meal trains, child care, yard work and home maintenance, etc. All I had to do was tell her the need, and she found someone from our church to fulfill it.
While the barrage of medical appointments that kept me away from home all day were unavoidable, we developed systems to make household tasks more efficient (e.g. we invested in a Skylight calendar for meal planning and grocery list making, and I shifted solely to grocery pickup - which also protected my immunocompromised children from shopping cart germs).
You Don't Have to Hit a Crisis Point to Start
The key concept here is handing off your mental load - regardless of its makeup.
What does this look like practically? It involves developing systems in your home that run without your oversight. Perhaps this is handing off chores such as laundry to your spouse, and loading the dishwasher to your child, both of who take ownership of the tasks moving forward. Developing automatic routines based on habit stacking can simplify tasks making them more manageable and efficient to complete. Creating a morning routine chart with pictures for your young children allows them to take ownership of all their morning tasks without you having to constantly stop what you’re doing to verbally direct them. (It also gives them needed independence). Develop a structure for any recurring decision or question in your home so you aren’t the default answer-giver.
Single moms with limited time and money can rely on rotating meal plans to take the mental load out of figuring out what to make. Partnering with other moms can provide opportunities for trading babysitting to make time for deep cleaning or running errands more efficiently without littles tagging along.
Developing systems that work for you and decrease mental load is the foundational shift that helped me, and is what I advocate for in my coaching and the products I’m creating for you.
Your nervous system dysregulation cannot recover if you remain the manager of the household. Unpopular opinion: that might also mean you need to let go of some control. (You’ll thank me for it later). The goal isn’t to get better at carrying the load - it’s to put it down.
