Spending the Day's Energy

People who have not experienced it reach for the nearest available comparison, and the nearest available comparison is being tired. It is the wrong one, and the mismatch causes a great deal of unnecessary hurt. Ordinary tiredness is proportionate to what you did, improves with rest, and yields to determination. The fatigue that accompanies multiple sclerosis, cancer treatment, long COVID, ME/CFS, rheumatoid arthritis, kidney disease, heart failure and brain injury does none of those things reliably.

It arrives without a matching cause. It is not fixed by a good night's sleep. It affects thinking as much as muscle — the sensation, frequently described, of the brain running through treacle. And for a substantial group of people, pushing through it does not build tolerance. It causes a delayed collapse that can last days.

Occupational therapists are among the professionals who work with this most closely, because fatigue is not really a symptom in the abstract. It is a constraint on what a person can do with a day, which is the profession's home ground.

The boom-and-bust cycle

Almost everyone with significant fatigue discovers the same pattern, usually the hard way.

A good day arrives. Energy feels close to normal, and there is a backlog: laundry, the garden, the shopping, a friend not seen in a month. The person does all of it, partly from relief and partly from a sense of owing it to everyone. The next day, often the two after, they are wiped out — and when function returns the backlog has grown, so the cycle repeats with a slightly lower ceiling each time.

This is not poor discipline. It is something more human: the wish to be your normal self on the days that seems possible, combined with the difficulty of stopping while you still feel able to continue. Stopping there feels like giving in. It is, in fact, the whole skill.

Pacing, properly understood

Pacing is the deliberate distribution of activity so that the day's demands stay within the day's supply — including a margin. It is not resting more. It is planning better, and it produces, over time, a higher total than boom-and-bust does.

It begins with information. A week or two of an activity and symptom diary usually reveals what memory does not: a particular hour, a particular task, a delay of twenty-four or forty-eight hours between exertion and consequence. That delay is exactly why the patterns are so hard to spot unaided — cause and effect sit too far apart to be linked intuitively.

From there, the practical work. Establishing how long an activity can be sustained before symptoms rise, then deliberately doing rather less. Breaking long tasks into segments with genuine rest between them — not a change of activity, but rest. Spreading heavy tasks across the week instead of clustering them. Rotating between physical, cognitive and social demands, which draw on different reserves.

A necessary distinction

It matters a great deal which kind of fatigue is being addressed, because the right approach differs.

In some conditions — certain cancer-related fatigue among them — carefully graded increases in activity are beneficial and well supported by evidence. Deconditioning is a real and treatable contributor, and gentle progressive activity helps.

In ME/CFS the picture is different. Here exertion beyond a person's limit produces a disproportionate, delayed and sometimes prolonged worsening of symptoms — post-exertional malaise. In 2021 the UK's National Institute for Health and Care Excellence revised its guidance on exactly this point, following sustained testimony from patients who had been harmed, and now advises clinicians not to offer graded exercise therapy, or any programme using fixed incremental increases in activity. South Africa has no equivalent national guideline, and NICE is widely referred to here in its absence. The approach instead is individualised: establish a sustainable baseline, stay within it, and adjust in either direction according to response rather than to a schedule. Where post-exertional malaise features in long COVID, the same caution applies.

Any competent therapist will establish which situation applies before advising, and will say plainly which one they think it is. Getting this wrong is not a minor error.

The part that is not about energy

Pacing asks people to do less than they are momentarily able to, and it collides with a set of deeply held beliefs: that effort is virtuous, that resting is idleness, that letting others down is unacceptable, that a person is what they produce. Those beliefs do not dissolve because a therapist has drawn a graph.

So a good portion of this work is not technical at all. It involves grief — for a previous capacity, a career, a version of a life — and that grief deserves acknowledgement rather than management. It involves negotiating with family and colleagues, given that fatigue is invisible and its bearer often looks well. And it involves the corrosive experience of not being believed, which many people with fatigue conditions have met repeatedly, sometimes from clinicians.

Being taken seriously is not a courtesy in this field. It is a precondition for anything else working.

The arithmetic of a life

The most useful reframing is to treat energy as a budget rather than a moral test. A budget can be overspent, and overspending has consequences. It can also be allocated, and the allocation is the person's own to make.

Some of it will go on things that must be done. But a budget spent entirely on obligations produces a life with nothing in it worth having. Part of the therapist's job is to insist that some energy is reserved, deliberately, for what the person actually cares about — the concert, the grandchild, the two hours in the studio — even when that means the laundry waits or a task is handed over.

Fatigue narrows a life. Pacing does not widen it back to what it was; it is honest to say so. What it does is give a person some authority over where the narrowing falls — and that turns out to be the difference between a life that is being lived and one that is merely being endured.
