Understanding Pacing Correctly: 3 Basic Rules – and the Mistakes Beginners Make Most Often

When people first hear the word "pacing" after an ME/CFS or Long Covid diagnosis, they often think it simply means resting more. But that exact misunderstanding is why pacing frequently fails to deliver the relief people hope for in practice – not because the method doesn't work, but because it's applied differently than intended. This article takes a closer look at three basic rules that often get short-changed when people start pacing, and names the pitfalls beginners fall into most often.

What Pacing Is – and What It Isn't

Pacing is a self-management approach that helps people learn to use their available energy in a way that keeps the risk of post-exertional malaise (PEM) – a delayed worsening after exertion – as low as possible. The UK's National Institute for Health and Care Excellence (NICE) describes pacing in its guideline as a self-directed approach that covers all types of activity – cognitive, physical, emotional and social – and helps people manage their energy with the focus on "reducing their risk of post-exertional malaise or worsening their symptoms by exceeding their limits". It's just as important to understand what pacing isn't: it is not an instruction to do as little as possible or to withdraw from life completely. Experts at Long Covid Physio explicitly emphasise that pacing is not simply an avoidance strategy, but a tool to minimise overexertion while still preserving as much of your life as possible. Pacing is also not the same as Graded Exercise Therapy (GET), where activity is increased according to a fixed schedule – an approach NICE explicitly no longer recommends when PEM is present.

The Three Basic Rules of Pacing

• Rule 1 – Prevent, don't react: Activity should be stopped before symptoms worsen, not only afterward. This is difficult because PEM is often delayed. According to the Workwell Foundation, worsening after exertion can set in well after the activity itself, often only after 24 to 48 hours. Anyone who only reacts once they already feel unwell is usually reacting too late.
• Rule 2 – All types of exertion count: Pacing isn't limited to physical movement. Cognitive effort (such as reading, doing calculations, or focused listening), emotional strain and social situations also consume energy and can trigger PEM. The Patient-Led Research Collaborative's guide for clinicians points out that pacing, as an activity-management strategy, balances rest and activity to prevent and reduce PEM – explicitly meaning more than just physical rest.
• Rule 3 – Stability before increase: Before any increase in activity is even considered, you first need a reliable, low-symptom baseline. This baseline is often lower than people initially assume, and it should stay stable over a longer period before any adjustment is considered – in very small steps and with patience, always in consultation with a medical or therapeutic professional.

The Most Common Beginner Mistakes in Pacing

Especially at the start, certain thought patterns tend to creep in that can make pacing ineffective:

• The boom-and-bust cycle: On a day with a bit more energy, people spontaneously "catch up" on a backlog of tasks – resulting in a crash shortly after. This pattern is described in research as the "boom-and-bust" or push-crash cycle: people with ME/CFS often try to ignore their symptoms and push through, which increases the risk of another worsening.
• Counting only movement, forgetting mind and feelings: Steps or heart rate are tracked meticulously, while a demanding conversation, a long letter from the doctor, or emotional stress quietly cost just as much energy.
• Only stopping once it gets "really bad": Because of the delayed PEM reaction, an activity often feels more harmless in the moment than it actually is – a dangerous fallacy.
• All-or-nothing thinking: A day "off plan" is treated as a complete setback, which leads either to giving up or to excessive strictness. Pacing is an ongoing learning process of trial and error, not a rulebook that has to fit perfectly from day one.
• Increasing too fast or in too-large steps: Out of impatience or comparison with other affected people, activity is ramped up abruptly instead of in very small, carefully observed steps.
• Self-blame after a crash: A crash is treated as a personal failure. But an occasional setback – caused by, say, unavoidable appointments or an infection – is simply part of living with a fluctuating, unpredictable illness, and says nothing about your own discipline.

A Note on Dealing with Setbacks

It's worth keeping in mind: even with careful pacing, PEM cannot always be prevented entirely. Some triggers – a doctor's appointment, a family gathering, unexpected exertion – are simply unavoidable. The goal of pacing isn't perfection, but reducing how often and how severely these setbacks occur in everyday life.

If you keep running into the same patterns with your own pacing, it often helps to systematically document your activity and symptoms over a longer period – for example with a structured tracking app. This makes it easier to recognise your own patterns and early-warning signs. Such documentation can't replace medical or therapeutic support, though: especially with severe or worsening symptoms, you should always seek specialist medical advice.
