Part two — application

How to move them

Dose, pacing and activity tolerance — and the one screening question that changes every recommendation on this page.

Read this first — energy limits

A note on post-exertional malaise

If post-exertional malaise is part of your picture — ME/CFS, Long Covid, some presentations of dysautonomia — the exercise guidance below changes. Pacing and staying inside your energy envelope come first, and graded exertion can do real harm. Work this out with a clinician who knows PEM.

Seeing the envelope

What pacing actually looks like

Two ways to picture the same thing: a finite daily budget, and a crash that lands a day after the effort that caused it.

Delayed

Worse 12–48 hours after the activity, not during it.

Disproportionate

A shower or a phone call can trigger it, not just a workout.

Multi-system

Cognition, sleep, temperature, gut and pain all worsen together.

Prolonged

Days to weeks to recover — and repeated crashes can lower the baseline.

Pacing

A day's energy is a budget, not a mood

Tap what a day contains. Watch what's left.

38 left in the account. Staying under, on good days as well as bad, is what keeps the baseline from sliding downward.

LIMIT22of 60

Illustrative only — everyone's envelope is a different size, and it changes week to week. The point is that the total is finite and cognitive, sensory and emotional load all draw on the same account.

Post-exertional malaise

The crash arrives late — that's what makes it hard to see

exertioncrash · 24–48h later0h36h72hfn

PEM is a delayed, disproportionate worsening after exertion that was tolerated at the time. Because the drop lands a day or two later, it is easily blamed on something else — which is why graded exercise programs can quietly cause harm here.

How the tiers work

Well-supported

Multiple RCTs or meta-analyses — in endometriosis or for the exact target symptom.

Emerging

Pilot RCTs or small trials with positive, direct signal. Real but not yet definitive.

Limited / indirect

Plausible mechanism; evidence borrowed from adjacent conditions or low-quality.

Minimal evidence

Little beyond anecdote, relaxation effect, or theory. Not disproven — just unstudied here.

Therapies

Movement and pain approaches, ranked by evidence

Mind-body work, physical modalities and exercise. The trial evidence is strongest in pelvic pain, but the target is the shared machinery: a sensitized nervous system, an inflammatory load, and a body that needs a repeatable dose.

01Trauma, Mood & the Nervous System

Psychological load and central sensitization sit at the heart of endo pain. These target the brain's threat and stress response rather than the lesion.

  • Well-supported

    CBT

    cognitive behavioural therapy

    The strongest psychological evidence in endometriosis specifically. In a 334-person RCT, endometriosis-tailored telehealth CBT beat education alone for both health-related quality of life and pain.

    Directly validated in endo — HaPPI RCT, Hum Reprod 2024 (n=334).

  • Emerging

    Mindfulness / MBSR

    meditation, body scan

    Pilot RCTs show reduced pain unpleasantness, lower pain catastrophizing, and improved quality-of-life mental-health domains. Effects on raw pain scores are inconsistent — the win is in how pain is experienced and coped with.

    Pilot RCTs; virtual MBSR feasibility studies, 2023–2024.

  • Emerging

    Journaling

    expressive / therapeutic writing

    Expressive writing has a modest evidence base across chronic illness populations for distress and coping. No endo-specific trials yet, but low-risk and mechanistically aligned with the stress–pain loop.

    Indirect — chronic-illness literature; no endo RCT.

  • Validated elsewhere

    EMDR

    eye movement desensitization & reprocessing

    A gold-standard, guideline-recommended treatment for PTSD and trauma — so if a patient carries medical or other trauma alongside endo, it's well-founded for that. It has not been studied as a treatment for endo pain itself.

    Strong for PTSD; untested for endo pain.

  • Validated elsewhere

    DBT skills

    distress tolerance, emotion regulation

    Well-established for emotion dysregulation; distress-tolerance and self-soothing skills transfer sensibly to chronic-pain flares. No endo-specific trials — best framed as a coping-skills adjunct, not a pain treatment.

    Strong in its own domain; extrapolated to pain coping.

  • Limited

    EFT / tapping

    emotional freedom technique

    Some trials in anxiety and general pain suggest benefit, but methodology is debated and the "meridian tapping" component adds little beyond exposure plus calming. No endo data. Harmless; keep expectations modest.

    Mixed general evidence; no endo trials.

  • Limited

    Wim Hof breathing

    cyclic hyperventilation + cold

    A controlled study showed the method can blunt an experimental inflammatory response, and many find it helps mood and stress. Not tested in endo. Safety note: never practice the breath-holds in or near water or while driving — fainting risk.

    Small mechanistic/inflammation studies; endo unstudied.

02Pain-Neuroscience & Brain Retraining

Approaches built on central sensitization — the idea that long-standing pelvic pain rewires how the brain and cord process danger signals, which persists even after lesions are removed.

  • Strong elsewhere

    Pain Reprocessing Therapy

    PRT

    The Boulder Back Pain Study found roughly two-thirds of chronic back-pain patients became pain-free or nearly so, with durable gains. Compelling for centrally-mediated pain — but the trial was back pain, not endo. The most promising untested transfer on this list.

    RCT n=151, JAMA Psychiatry 2022; no endo trial yet.

  • Minimal

    DNRS

    Dynamic Neural Retraining System

    A commercial limbic-retraining program with an enthusiastic following, but the peer-reviewed evidence is thin and largely uncontrolled. The underlying neuroplasticity premise overlaps with PRT — the difference is PRT has an RCT and DNRS essentially doesn't.

    Mostly testimonial / uncontrolled data.

03Movement & Exercise

The category patients ask about most — and where the honest answer is "beneficial and safe, but the trials are still small." Exercise physiology gives a plausible why alongside the symptom data.

  • Emerging

    Physical activity & general exercise

    Systematic reviews of the RCTs (six trials, ~251 women) find consistent benefit for quality of life, pain intensity, mental health, and pelvic-floor function — but overall study quality is low and effects on disease symptoms remain inconclusive.

    Meta-analysis of 6 RCTs, n=251, PLOS One 2025.

  • Emerging

    Aerobic / cardiovascular training

    walking, cycling, swimming, moderate continuous

    The workhorse of most endo exercise trials, and the modality with the clearest physiological rationale: regular training raises anti-inflammatory cytokines, lowers circulating estrogen, dampens peritoneal oxidative stress, and engages endogenous pain modulation via the HPA axis.

    Mechanistic rationale + symptom RCTs; aerobic-only trials still small.

  • Emerging

    Supervised therapeutic exercise

    multimodal, lumbopelvic, physio-led

    The most structured evidence in endo. Physio-EndEA (n=31) — a 9-week supervised, personalized program — improved quality of life with large effect sizes held at one year, plus reduced dyspareunia, higher pressure-pain thresholds, and gains in trunk strength.

    Physio-EndEA RCT n=31; multimodal RCT, Arch Phys Med Rehabil 2023.

  • Emerging

    Resistance / strength training

    bodyweight, bands, load-bearing

    Rarely tested in isolation, but a component of the supervised programs that worked. Skeletal muscle acts as an endocrine organ, releasing anti-inflammatory myokines, and load-bearing work supports bone density — relevant under hormonal suppression. Build gradually.

    Embedded in multimodal RCTs; myokine/bone rationale.

  • Emerging

    Yoga

    restorative, Hatha, cycle-synced, gentle vinyasa

    A pilot RCT of an 8-week Hatha program reduced pelvic pain and improved quality of life; yoga was also an arm in the large HaPPI trial. Signal is real, though CBT outperformed it there. Restorative and cycle-aware sequencing fits the flare pattern best.

    Pilot RCT n=40 (Campinas); HaPPI yoga arm 2024.

  • Emerging

    Pelvic floor physical therapy

    manual release, down-training, PFM physio

    Widely recommended and clinically sensible — chronic pelvic pain drives protective pelvic-floor hypertonicity. Small RCTs show improved pain, dyspareunia, and function; a 2025 systematic review pulls this together while noting the evidence is still maturing.

    Systematic review, Pain Medicine 2025; multiple small RCTs.

  • Untested (safe)

    Pilates

    mat, reformer, props

    No endo-specific trials, but core stability and controlled, low-impact movement align with the broader exercise evidence. Best positioned as a well-tolerated on-ramp — reasonable to recommend as movement, not as a studied intervention.

    No direct evidence; consistent with exercise data.

04Physical & Energy Modalities

Device- and touch-based approaches, ranging from those with real trial data (TENS, acupuncture, heat) to those resting mostly on plausibility.

  • Emerging

    TENS

    transcutaneous electrical nerve stimulation

    Good evidence for primary dysmenorrhea and positive small RCTs directly in endometriosis. Non-drug, self-administered, excellent safety profile — one of the more evidence-backed at-home tools here.

    Endo RCTs (n=22; n=36) + strong dysmenorrhea data.

  • Emerging (mixed)

    Acupuncture

    Meta-analyses report meaningful pain reduction and CA-125 changes in endo — but the trials are mostly small, heterogeneous, and carry publication-bias concerns, so more cautious reviews land on "uncertain." Reasonable to offer when pain persists despite standard care.

    SR of 14 RCTs, n=793, Arch Gynecol Obstet 2024.

  • Well-supported

    Heat therapy

    heating pad, heat wrap

    Topical heat has solid RCT support for menstrual and cramping pain — in some trials comparable to NSAIDs. Not a disease-modifier, but a legitimately evidence-based, first-line comfort measure for the cyclical pain component.

    Validated for dysmenorrhea; symptomatic relief in endo.

  • Limited

    Red light / photobiomodulation

    PBM, low-level laser

    Best data are in dysmenorrhea (pulsed 630 nm reducing pain and prostaglandins) plus a 2018 endo laser RCT and small transvaginal PBM pilots. Mechanistically plausible; endo-specific evidence is early.

    Dysmenorrhea RCTs + small endo/CPP pilots.

  • Limited

    PEMF

    pulsed electromagnetic field

    Has a general anti-inflammatory and pain-modulation research base in other conditions, but no quality endometriosis trials. Low risk; currently theory-and-adjacent-evidence rather than endo-proven.

    Adjacent-condition data; no endo trials.

  • Minimal

    Craniosacral therapy

    Gentle and generally relaxing, but the evidence base is weak and the proposed mechanism is not well-substantiated. Any benefit likely runs through relaxation and manual-contact effects rather than anything endo-specific.

    Weak overall evidence; no endo support.

  • Minimal

    Energy work

    Reiki, therapeutic touch

    No credible evidence of a specific physiological effect beyond relaxation and placebo. The relaxation and felt-care components can still support nervous-system regulation — worth framing honestly as comfort and ritual, not treatment.

    No specific-effect evidence; relaxation value only.

Practical reads

Choosing between the near-identical

Heating pad vs. infrared heating pad

Standard heating pad

Conductive surface heat, penetrating a few millimetres. This is the version with real RCT evidence for menstrual cramp relief. Fast, cheap, reliable for the cyclical pain layer.

Infrared heating pad

Radiant heat that penetrates deeper into muscle and connective tissue. Plausibly better for myofascial and pelvic-floor tension, but the endo evidence is thinner than for standard heat.

Practical read: Standard heat is the evidence-backed default for cramps; infrared is a reasonable upgrade for deeper muscular tension, framed as emerging rather than proven.

Red light vs. blue light

Red / near-infrared (≈630–850 nm)

Penetrates deep enough to reach pelvic tissue; acts on mitochondria and inflammatory signalling. This is the wavelength studied for menstrual and pelvic pain — and it outperformed blue in a head-to-head dysmenorrhea study.

Blue (≈460 nm)

Shallow penetration — mostly a skin-surface tool (acne, some circadian and mood uses). It does not reach deep pelvic structures, so it's not the relevant color for pelvic pain.

Practical read: For pelvic and menstrual pain, red / near-infrared is the right choice. Still classified emerging for endo specifically.

Dosing it: how much, how hard, and when

What the evidence supports

Moderate-intensity, low-impact, consistent movement — walking, swimming, cycling, gentle strength. Build gradually toward roughly 150 min/week on lower pain days. Warm up, keep sessions short during flares (10–15 min), and treat rest as legitimate on high-pain days.

Where to be cautious

Strenuous, high-intensity work — especially during menstruation — raises intra-abdominal pressure and can trigger a flare. The pattern to avoid is overdo → crash → stop → repeat.

Practical read: The therapeutic dose is moderate and repeatable, cycle-aware, not maximal. Stop for shooting pelvic pain, bowel pressure, or dizziness.
