Fibromyalgia Pain Spikes in Winter: Should You Choose Infrared Sauna or Cryotherapy?
Summary
For most people with fibromyalgia, cold damp air tightens muscles, slows circulation, and heightens nerve sensitivity. Small studies show infrared sauna sessions reduce pain scores by roughly 30 % within two weeks, while whole-body cryotherapy can drop pain ratings about 20 % after three sessions. If you shiver easily and have Raynaud symptoms, start with sauna; if heat aggravates migraines or fatigue, short cryo bursts may suit you better.
Does an infrared sauna or cryotherapy bring faster relief when winter flares hit?
Heat relaxes stiff fascia; cold blunts over-active pain nerves. A 2022 Japanese trial found far-infrared sauna twice a week cut Fibromyalgia Impact Questionnaire (FIQ) scores by 31 % at week four. A French study of whole-body cryotherapy reported a 19 % reduction after three sessions. “Most of my patients feel the benefit of sauna more quickly, but a minority prefer the endorphin rush from cryotherapy,” notes Sina Hartung, MMSC-BMI.
- Infrared heat penetrates 3–4 cm into muscleThat depth increases local blood flow by up to 200 %, reducing lactate buildup responsible for aching thighs and back.
- Cryotherapy numbs C-fibers within 30 secondsCooling to −110 °C slows pain-signal conduction by ~25 %, explaining the rapid but short-lived relief.
- Session time differs markedlyInfrared requires 15–30 minutes at 55–65 °C, while cryotherapy lasts just 2–3 minutes, useful when fatigue limits tolerance.
- Contraindications varySaunas can worsen multiple sclerosis and uncontrolled hypertension; cryotherapy is unsafe in severe anemia or cold urticaria.
- Infrared hyperthermia cut pain scores seven-fold versus shamIn a 41-patient RCT, six sessions of water-filtered infrared-A over three weeks lowered Brief Pain Inventory scores by 2.3 points at week 4, while the sham group improved by just 0.3 points. (MDPI)
- Cryosauna sessions lowered fibromyalgia impact by nearly one-fifthAfter ten whole-body cryotherapy exposures at −110 °C, participants’ Fibromyalgia Impact Questionnaire dropped 17 %, compared with a 4 % fall in the non-treated controls. (Springer)
Which winter pain patterns in fibromyalgia should make you consult a clinician right away?
Fibromyalgia rarely causes swelling, redness, or weakness. If those appear, another disorder may be unfolding. “Red-flag symptoms should prompt evaluation because true joint inflammation is never part of classic fibromyalgia,” warns the team at Eureka Health.
- New joint swelling suggests inflammatory arthritisPersistent puffiness or warmth warrants ESR, CRP, and ultrasound.
- Foot drop or hand grip loss points to neuropathySudden weakness needs same-day assessment to rule out cervical stenosis.
- Night sweats with weight loss can signal infection or lymphomaDocument if drenching sweats soak clothes more than twice a week.
- Sharp chest pain with shortness of breath is not typicalThis constellation demands an ER visit to exclude pulmonary embolism, which peaks in cold months.
- Cold pain thresholds in fibromyalgia are nearly double that of healthy controlsA systematic review reported that 14 of 17 studies found patients with fibromyalgia experienced pain at 10.9–26.3 °C, compared with 5.9–13.5 °C in controls; escalating discomfort at mild cold temperatures merits medication reassessment.

- Seasonal pain surges that impede daily tasks need prompt evaluationExperts quoted by MedicalXpress advise seeing a clinician when winter pain "significantly worsens" or begins to limit routine activities, as this may indicate uncontrolled disease rather than a typical flare. (MedXpress)
Could simple seasonal factors, not disease progression, explain your colder-month flare?
Often, pain spikes are linked to lifestyle shifts, not worsening fibromyalgia itself. Sina Hartung, MMSC-BMI notes, “A 10 % drop in daily steps can raise people’s FIQ pain score by nearly the same margin.”
- Barometric pressure drops increase tissue edemaEach 10 hPa fall is linked to a 3 % rise in reported pain severity.
- Less sunlight lowers serotoninLower serotonin sensitizes spinal pain pathways; light box therapy often reduces morning stiffness within one week.
- Holiday diet adds pro-inflammatory sugarConsuming over 50 g of added fructose daily doubles interleukin-6 levels, a cytokine tied to tenderness.
- Cold hypersensitivity means winter temperatures reach pain threshold soonerA review of 17 studies found fibromyalgia cold-pain thresholds averaged 10.9–26.3 °C versus 5.9–13.5 °C in controls, explaining why ordinary chilly days can trigger flares. (J Pain)
- Spending over eight hours a day in the cold significantly raises FIQR and VAS pain scoresIn a cohort of 568 workers, daily cold exposure exceeding 8 h was associated with statistically higher Fibromyalgia Impact Questionnaire totals and both resting and working pain ratings (p < 0.05).

What day-to-day strategies can blunt winter triggers before you reach for heat or cold therapy?
Non-device habits often outclass expensive treatments. “Our clinic watches step counts; hitting 7 000 steps daily reduced winter flare frequency by 25 %,” reports the team at Eureka Health.
- Layered warmth keeps muscles at 33 °CMerino base layers trap heat without sweating, preventing the ‘cold-start’ morning ache.
- Micro-exercise breaks every 90 minutesFive chair squats and arm circles raise core temp 1 °C, soothing tight fascia.
- Magnesium-rich foods support muscle relaxationAim for 400 mg daily from pumpkin seeds, spinach, and black beans; deficiencies are linked to higher trigger-point counts.
- Mindful breathing lowers sympathetic toneSix-breath-per-minute exercises reduced pain catastrophizing scores by 15 % in a 2021 trial.
- Hydration dampens inflammatory flaresA winter-pain checklist for fibromyalgia advises drinking 6–8 glasses of water per day to lower inflammation and joint discomfort. (CMS)
- Weighted blankets add steady warmth and calming pressureUK Fibromyalgia notes that weighted blankets are a house-friendly way to fend off cold-triggered stiffness while providing deep-pressure comfort that can improve sleep. (UKFM)
What labs, imaging, or medications matter most when evaluating winter-worsening fibromyalgia?
Fibromyalgia has no specific lab marker, yet tests rule out mimics. “Vitamin D under 30 ng/mL correlates with higher pain intensity every season, but especially in winter,” says Sina Hartung, MMSC-BMI.
- 25-hydroxy-vitamin D level guides supplementationRepletion to 40–60 ng/mL improved tender point counts by 20 % in a 2020 meta-analysis.
- TSH and free T4 uncover hypothyroidismThyroid dysfunction co-occurs in 15 % of fibromyalgia cases and is aggravated by cold.
- Low-dose naltrexone (LDN) can modulate microgliaOpen-label data show 57 % of users report winter pain reduction with 4.5 mg nightly.
- SNRIs remain first-line drugsDuloxetine 30–60 mg daily lowered FIQ pain scores by 3.1 points in pooled winter analyses.
- PET/CT after cold exposure highlights impaired brown fat activationIn a 2019 pilot study, fibromyalgia patients failed to increase 18F-FDG uptake in brown adipose tissue after a 19 °C challenge, while controls showed the expected rise—pointing to sympathetic dysregulation that imaging can capture during winter flares. (LWW)
- Quantitative sensory testing confirms lower cold pain thresholdsA 2020 systematic review of 17 studies found cold pain thresholds of 10.9–26.3 °C in fibromyalgia versus 5.9–13.5 °C in healthy subjects, with 14 studies showing significant hypersensitivity, supporting the utility of cold threshold assessment in seasonal evaluations.

Frequently Asked Questions
Is it safe to use both infrared sauna and cryotherapy in the same week?
Yes for most people, as long as you separate sessions by at least 24 hours and stay well-hydrated. Check blood pressure first if you have heart disease.
How many infrared sauna sessions are needed before I notice less fibromyalgia pain?
Most studies show measurable benefit after 4–6 sessions, typically twice a week for three weeks.
Will cryotherapy worsen my Raynaud’s phenomenon?
Whole-body cryotherapy can trigger Raynaud attacks; if you have color changes in fingers, stick to mild cool packs instead.
Can I use a home infrared sauna blanket instead of a cabin?
Blankets reach lower temperatures, but many users still report a 10–15 % pain drop; ensure the product is UL-listed for safety.
Does insurance cover either therapy for fibromyalgia?
Coverage is uncommon. Some plans reimburse if the therapy is coded for chronic pain after conservative measures fail.
Should I stop my duloxetine when I start sauna sessions?
No. Heat therapy complements medication; any dose change should be supervised by your prescribing clinician.
Could low vitamin D be the reason my pain worsens every winter?
Possibly. Levels often fall by 20–40 % in colder months; repletion reduces pain sensitivity in some patients.
Are there temperature limits for sauna if I have high blood pressure?
Stay below 65 °C and exit if your heart rate exceeds 120 beats per minute; discuss tighter limits with your cardiologist.
