When Your Capacity Changes: Listening Before Your Body Makes You Stop
I had quite a lovely birthday weekend planned.
My son had travelled home from university and was staying for the weekend. My husband had booked breakfast at a beautiful local spot, and we were going to visit the markets before I headed to a rehearsal later in the day.
There was time together to look forward to and the quiet pleasure of having everyone under the same roof for a little while.
Then I went to yoga with a headache.
I came home, went to bed and stayed there for most of three days.
The breakfast booking was cancelled. The markets and rehearsal disappeared from the plan. My birthday weekend became much smaller and quieter than any of us had expected.
When the body takes over
What struck me most was how completely my attention changed.
Ordinarily, my mind is busy. I think about my work, my family, the next newsletter, the garden, the things I need to organise and the conversations I need to have. Like many women, I can carry several threads of thought at once—sometimes far more than is useful.
But while I was unwell, almost all of that stopped.
I wasn’t thinking about what I should be achieving or what I might be falling behind on. Even beautiful birthday messages from people I care about sat outside the small circle of what I could manage. My attention narrowed to feeling better and to the people immediately around me.
My body had made the decision for me: my capacity was now extremely limited.
There was no negotiating with it, finding a more efficient system or squeezing in one more task. I had to stop.
It was an unusually clear example of something I often discuss with women in my work: being capable is not the same as having capacity.
Capacity is not fixed
We often behave as though our capacity should remain consistent from one day to the next.
If we managed the workload last week, we expect to manage it this week. If we were patient yesterday, we think we should be equally patient today. If a routine worked for us last month, we can become frustrated when it suddenly feels difficult.
But capacity is not a fixed personal quality. It can change across a season of life, from one day to another and even from one part of the day to the next.
Physical illness can change it dramatically, as I experienced. But it can also be affected by grief, persistent stress, hormonal changes, mental ill-health, caring responsibilities, uncertainty or a demanding period at work.
There are smaller influences too: how well we slept, whether we have eaten, how much stimulation we have encountered, whether we have moved our body, the number of decisions we have already made and what else we are carrying emotionally.
These influences do not make us unreliable or weak. They make us human.
The difficulty is that the quieter changes in capacity are much easier to ignore than an illness that puts us in bed.
We may notice ourselves becoming more irritable, indecisive or scattered. A straightforward task feels unexpectedly difficult. We reach the end of the day with nothing left for the people we love—or for ourselves.
Instead of treating these signs as information, we often turn them into a judgement:
Why can’t I cope with this? I should be able to manage. I just need to get myself together.
Yet self-criticism does not restore capacity. It simply becomes one more thing to carry.
Feeling better does not mean being fully restored
By Monday evening, I could feel my mind beginning to come back online. Thoughts and ideas started returning. I wanted to respond to messages and work out what needed my attention.
That first return of energy can be deceptive.
The temptation is to interpret feeling a little better as being completely well—and then rush to catch up on everything that was postponed. But capacity often returns gradually. Our enthusiasm may come back before our physical energy, concentration or patience has fully recovered.
Fortunately, I have learnt over the years that resuming does not have to mean rushing.
I could begin with what was necessary, leave some things for later and allow the pace to increase slowly. That isn’t always easy, particularly when work has accumulated or other people need something from us. But overriding our current capacity rarely makes it expand more quickly.
There is an important distinction between gently moving forward and immediately returning to full speed.
Paying attention without becoming preoccupied
Listening to our bodies does not require monitoring every sensation or interpreting every difficult day as a sign that something is wrong.
It can be much simpler than that.
It may mean noticing that today you have less patience than usual and reconsidering the unnecessary commitment you were about to add. It may mean recognising that a conversation requires more emotional energy than you currently have. It may mean eating before making an important decision, going outside for ten minutes, asking someone to share a responsibility or choosing an earlier night.
Sometimes it will mean seeking appropriate medical or mental health support, particularly when changes are persistent, concerning or interfering with daily life.
The aim is not to build a life in which we never feel tired, stretched or uncomfortable. Nor is it to use capacity as a reason to avoid everything difficult.
It is to respond to the reality of what is available to us, rather than continually measuring ourselves against what we think should be available.
A brief capacity check
If you have been expecting yourself to keep moving at the same pace, you might pause and consider:
What is influencing my capacity today?
Think about sleep, nourishment, physical health, stress, emotions, responsibilities and the environment around you.What signs have I been overlooking?
Perhaps you are more forgetful, reactive, restless or tired than usual. Perhaps ordinary decisions are taking much more effort.What genuinely needs my energy today?
Not everything that could be done needs to be done now.What could be reduced, delayed, simplified or shared?
Supporting yourself may require a practical change, not another wellbeing practice added to the list.What would a gradual return look like?
If your capacity is beginning to increase, consider what can be resumed first—and what can wait a little longer.
These questions are not another assessment to pass. They are simply a way of meeting yourself more accurately.
The body is always part of the conversation
My birthday weekend certainly didn’t unfold as planned. I would have preferred the breakfast, the markets and the celebration we had imagined.
But the experience was a powerful reminder that the mind and body are not separate projects. Whether the demands on us are physical, mental or emotional, they draw on the same whole person—and sometimes that person needs plans to change.
Most changes in capacity will not be as unmistakable as being sent to bed for three days. They are more likely to arrive as subtle shifts: less energy, a shorter fuse, difficulty concentrating or the quiet sense that something has become too much.
We do not need to beat ourselves up for those changes. We do need to pay attention.
Because sometimes wisdom is not pushing through or finding a way to do everything anyway.
Sometimes it is recognising what is true today—and responding with honesty, practicality and a little more self-kindness.
If this reflection resonates, the newly revised edition of Rest & Rise offers practical, neuroscience-informed support for understanding stress, overwhelm and changing capacity. A companion journal and Guided Bundle are also available for women who would like to explore the ideas more deeply.
