You already knew about the lists. The calendar. The knowing which child needs which form signed by when and where the spare batteries live and what everyone is out of and who has an appointment on Thursday.
You knew about the mental load. You have probably even said the words out loud. But there is a part of it that research has only recently started to name, and when I read it I had to put my phone down for a second because I felt so completely understood and so completely furious at the same time.
The worrying counts too.
Not just the doing. Not just the coordinating. The anticipating. The lying awake running through the next week. The noticing that your daughter seems quieter than usual and filing that quietly away. The scanning for problems before they happen so you can solve them before anyone else even realises there was a problem to solve.
New research is calling this anticipatory labour. And it qualifies, without question, as unpaid invisible work.
The mental load has always been heavier than it looked. But it turns out it was even heavier than most of us realised, because we were not even counting the part that never ends. This post is about what that research says, what it actually costs you, and what you can do with that information.
What The Mental Load Actually Includes And Why The List Is Longer Than You Thought
The term “mental load” was popularised in a famous 2017 French comic by Emma, which went globally viral because it named something millions of women had been living inside without having words for. The mental load is the invisible cognitive work of managing a household and family: remembering, planning, anticipating, organising, noticing.
It is the difference between doing a task and being responsible for the task existing.
Your partner might do the grocery run, but you made the list, you noticed the fridge was getting low three days ago, you mentally tracked what was running out, you remembered that your daughter has a thing at school on Friday that needs specific snacks. He bought the groceries. You managed the entire system around the groceries. Those are not the same amount of work.
Research from sociologists and cognitive scientists has been mapping the full scope of what falls under the mental load umbrella, and it is bigger than most people assume:
- The logistical coordination: appointments, school schedules, activities, admin
- The household management: what needs cleaning, what needs buying, what is about to run out
- The relational tracking: who needs what emotionally, who is having a hard week, who needs more attention
- The anticipatory management: planning for things before they become problems
- And now, officially: the worrying. The anticipatory anxiety. The mental rehearsal of everything that could go wrong.
When you put the full picture together, the cognitive load of running a family is genuinely staggering. And most of it is invisible. Most of it does not appear in any task list. Most of it lives entirely in your head, running in the background like an app that never fully closes.
Research consistently finds that women carry approximately 71 percent of this invisible load in heterosexual households. If you want the fuller picture on how that breakdown happens and why, this post on why you are carrying 71 percent of the mental load and nobody even notices goes deep on the data.
The Research That Finally Named The Worry As Work
The specific piece of research that caught my attention came from a study examining what sociologists call “anticipatory labour.” The researchers wanted to understand not just what moms do but what moms think about in preparation for doing.
What they found was that a significant proportion of the mental load that women carry exists entirely in the future tense. It is the cognitive work of anticipating needs, planning for outcomes, worrying about possibilities, and running through contingencies before they become real problems.
And crucially: this work is invisible not just to partners but often to the moms carrying it themselves.
Because it does not feel like work in the traditional sense. It happens while you are making dinner or trying to sleep or waiting at school pickup. It does not have a clear start or end point. It does not produce a visible output. Nobody sees it happening. You do not even always notice you are doing it. But your brain is working. Your nervous system is engaged. Your mental energy is being spent.
The study also found something that genuinely made my stomach drop. Anticipatory labour does not switch off in the way that physical tasks do. When you finish the dishes, the dishes are done. When you have been worrying about whether your child is happy at school or running through the logistics of next month, the worrying does not end with a satisfying completion. It just continues, cycling, finding new threads to follow, never fully resolving.
This is why you cannot switch your brain off at night. This is why your body is exhausted even on the days when you “did not do very much.” Your mind has been working all day in ways that nobody counted, including you.
What Anticipatory Labour Actually Costs You
The practical cost of carrying the worry alongside the logistics is enormous, and it compounds in ways that are hard to trace because the effects look like personality traits rather than what they actually are, which is depletion.
When you are constantly running the forward simulation of everything that needs managing, your brain stays in a steady, quiet state of alert. Not panic. Not crisis. Just a steady, quiet, unrelenting readiness. Always on. Always scanning.
That constant readiness has a biological cost.
Your nervous system runs on resources. Attention is finite. Decision-making depletes. The research on cognitive load consistently shows that the more we hold in active mental management, the less capacity we have for everything else, including patience, creativity, presence, joy.
The mom who snaps at her kids at 5pm is not a bad mother. She is a woman who has been running a complex cognitive operation since before she opened her eyes this morning and simply has nothing left. The mental load of motherhood and why your partner does not see it is one of the clearest explanations I have found for why this particular kind of depletion gets so badly misread as a mood problem or a patience problem, when it is really a cognitive load problem.
What anticipatory labour specifically costs is rest. Real rest. The kind where your brain actually lets go.
Because as long as you are the one holding the mental load, you cannot fully put it down. Even in the bath. Even when you finally get to sit down. Even in the ten minutes of quiet you carved out for yourself. The part of your brain that is managing the system does not go on holiday just because your body is still.
Why The Mental Load Of Worrying Never Clocks Off
Here is the thing about physical tasks: they end.
You make dinner. Dinner is done. You fold the laundry. The laundry is folded. The task has a visible finish line. You cross it. You feel the small but real satisfaction of a thing completed.
Worrying has no finish line.
The worry about whether your child is struggling socially does not end when you check in with her teacher. It shifts to the next question: what if the teacher did not notice? What if she is fine at school and still lonely inside? What if I am reading it wrong and it is something else entirely? The completion of one worry opens a door to three more. This is not anxiety in the clinical sense, though for some of us it absolutely is that too. This is the functional reality of being the person who is responsible for noticing.
Because someone has to notice. And in most households, that person is the mother. So your brain stays responsible for the noticing, and responsible brains do not get to stop noticing just because it is Tuesday evening and you would really like them to.
The research on anticipatory labour describes this as a form of “cognitive housekeeping” that has no natural end. Unlike the dishes, it is never actually finished. It is just… ongoing. Continuous. Woven into the texture of your days in a way that makes it almost impossible to separate from who you are.
Which is partly why it is so hard to put down. You have been carrying it so long that it no longer feels like something you are doing. It feels like something you are.
The Garbage App Moment And Why The Small Things Break You
In the Netherlands, bin collection works on a rotating schedule. Paper one week, general waste another, always different, never predictable without checking. There is an app. It sends notifications the night before so you remember which bin to put out.
I was always the one who saw the notification. Processed it. Mentally filed it. And then told my boyfriend which bin to take out.
One evening, after a particularly long and overstimulating day, I completely fell apart over the bins.
Not the bins themselves. The bins were fine. What I was falling apart over was what the bins represented. The fact that I had been the one who downloaded the app. Set up the notifications. Absorbed the information. Made the decision. And then presented it to him so he could perform the visible part of the task. He took out the bin. I managed the entire system. We both knew he had “helped.” Only one of us knew the actual cost.
That is anticipatory labour made visible. And it is funny and maddening and deeply exhausting in equal measure. 😅
The worrying, the anticipating, the noticing, the being ready: these are not bonuses on top of the mental load. They are the mental load. And if you are ready to start separating what is genuinely yours to carry from what has just quietly landed on you because nobody else picked it up, the Cut, See, Unload Kit was made for exactly this. It is a practical way to start seeing the weight before you can put any of it down.
What Happens When You Try To Hand The Worry Over
This is the part where people often say: just stop worrying. Delegate. Let things go.
Which is advice that comes from someone who does not understand what it actually means to be the person responsible for the system.
When you hand over a task, the task moves. When you hand over the mental load, the responsibility for noticing and managing and anticipating has to move with it. Which means the other person has to genuinely take it on. Not just do it when asked. Not just complete the task when presented. But hold the whole system of knowing about it.
And that transition is genuinely complicated. It does not happen by announcing it.
Research on shared mental load shows that the most effective transfers happen when responsibility for an entire domain shifts, not just individual tasks. Not “you do the bins this week” but “you are now responsible for knowing when the bins go out, checking the app, and making it happen without being asked.” That is a different thing entirely.
This post on why “just tell me what to do” is not help explains the dynamic in a way that might be useful if you are trying to have this conversation with someone who keeps asking what they can do and not understanding why that question is part of the problem.
The short version is this: you cannot fully unload the worry until you fully unload the responsibility that generates it. And that takes a real conversation, real negotiation, and real follow through. It is doable. But it is more than a task list.
How To Start Putting Some Of It Down
I want to be real with you here. There is no quick fix for carrying the mental load. The structural reasons it lands on you will not dissolve with one conversation or one good evening of delegating.
But you can start to put pieces of it down. And the beginning is usually the same place.
See it first.
You cannot put down what you cannot see. And the anticipatory labour, the worrying, the cognitive housekeeping that runs constantly in the background, is genuinely hard to see because it has become so woven into your daily experience that it feels like just… thinking. Just being responsible. Just being you.
Naming it as work, not as a personality trait or a neurotic tendency or “just the way your brain works,” changes something. It becomes a thing you are doing. And things you are doing can be examined, shared, renegotiated.
Start by noticing, for one day, every time your brain is working in advance. Every time you are thinking about something that has not happened yet, planning for something that has not been asked for yet, worrying about something before it becomes a problem. Notice how constant it is. How long the list gets.
Then notice: how much of that is genuinely yours to carry?
The Cut, See, Unload Kit is a practical tool for exactly this process. It helps you cut through the fog of everything you are carrying, see what is actually yours and what just ended up with you by default, and start the process of putting some of it down without catastrophe.
The Worry Is Work. You Were Not Imagining It.
The mental load was always real. The research that named it changed how a generation of women talked about what they were experiencing at home.
And now the research that names the worry as part of the mental load changes it again. Because if you have spent years wondering why you cannot relax even when nothing urgent is happening, wondering why your brain will not switch off even when everything is technically fine, wondering why the exhaustion does not lift even after a rest… this might be why.
You were not being neurotic. You were not catastrophising. You were not bad at resting.
You were working. In the way that does not get counted. In the way that does not get thanked. In the way that never actually ends, because the system has no finish line when you are the only one holding it.
You were working, and you deserved to have that seen. Now you do. 💛
