Pacing for ME/CFS: Making Everyday Life Work

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) makes pacing the central strategy — not an afterthought. Here's how it works in practice.

ME/CFS (myalgic encephalomyelitis/chronic fatigue syndrome) is a complex multisystem illness classified by the WHO as a neurological condition. Its hallmark feature is post-exertional malaise (PEM): a delayed, often severe worsening after physical, cognitive or emotional exertion — typically 12 to 72 hours later. That's exactly why pacing in ME/CFS isn't a supplementary suggestion — it's the central, evidence-based management strategy.

Why classic exercise training doesn't work here

The UK's NICE NG206 guideline explicitly advised in 2021 against prescribing graded exercise therapy (GET) to people with ME/CFS — a reversal of earlier recommendations. The reason: PEM means more activity doesn't lead to greater capacity, it leads to worsening. Pacing addresses this directly: matching activity to the actual, often severely limited exertion threshold, rather than gradually increasing it.

Pacing in practice: the basic principles

  • Find your baseline. How much activity is possible on an average day without triggering a crash? That value is the starting point, not the goal.
  • Heart-rate pacing as a rule of thumb. Resting heart rate + 15 beats is used in many sources (including the Workwell Foundation) as a rough orientation. Whether worsening occurs less often below that number has not been tested in a controlled study; the only peer-reviewed threshold is 10 % below the ventilatory threshold measured by exercise testing.
  • Build in rest before you're forced to. Short, regular breaks before exhaustion tend to work better than long breaks afterward.
  • Spread activity across the day. Three short blocks are often better tolerated in ME/CFS than one long one.

How mypacing helps in practice

The pacing calculator translates resting heart rate and symptom precursors into a rough, non-binding orientation. The FUNCAP calculator is a validated assessment of functional capacity in two versions (27 questions for tracking, 55 in full). The doctor's report summarizes pacing data and Bell score; the daily tracking view shows patterns before crashes rather than looking at single days in isolation.

Note: mypacing is not a medical device and does not replace medical diagnosis or treatment.
