Whole-Body Cryotherapy is effective as an adjunct for chronic pain across fibromyalgia, chronic low back pain, and MS, with significant VAS pain reduction in most studies.

What complicates this
Effect size varies by condition and protocol; adjunct only.
Moderate evidence· Points toward a benefit
In fibromyalgia, Whole-Body Cryotherapy significantly improves pain (VAS) and quality of life (FIQ) after 6–20 sessions; pain returns toward baseline within ~3 months after stopping, so maintenance sessions are needed.
Studied in Adults with fibromyalgia (best when added to multidisciplinary rehab)clinical studies

Scoping review 2022 (MDPI Applied Sciences, 12 publications); RCT 2018 (PMID 29458933); follow-up 2024 (PMC11355555). Source: MDPI Applied Sciences 12(9):4794. Dossier claim id WBC-P2.
What complicates this
Pain relapses after cessation; ongoing maintenance appears necessary.
Moderate evidence· Points toward a benefit
For DOMS and jump performance, Whole-Body Cryotherapy is similarly effective to cold-water immersion (13 RCTs, n=214); neither clearly superior — WBC preferred when immersion is impractical.

What complicates this
Head-to-head equivalence; some protocols favor CWI at earlier timepoints.
Moderate evidence· Points toward a benefit
Whole-Body Cryotherapy as add-on to pharmacotherapy significantly reduced HAM-D17 and BDI-II depression scores vs. control (Hedges' g = 0.76 between-groups); NOT validated as standalone psychiatric treatment.

Whole-Body Cryotherapy as adjunct significantly improves BASDAI (disease activity), VAS pain, BASFI (function), and CRP vs. controls in ankylosing spondylitis (first meta-analysis, 5 studies, n=310).

What complicates this
Protocol heterogeneity across studies (-60C to -110C).
Moderate evidence· Points toward a benefit
Whole-Body Cryotherapy significantly improves countermovement jump (CMJ) recovery at 1–48h post-exercise vs. passive control; DOMS reduction is significant at 24h+ but not immediately post-exercise.

Whole-Body Cryotherapy significantly reduces IL-1β (SMD -2.08 pg/mL) and increases anti-inflammatory IL-10 (SMD +0.78 pg/mL) across 11 RCTs (n=274); athletes benefit most for IL-1β, individuals with obesity most for IL-10.

What complicates this
IL-6 and TNF-α reductions trended but did not reach significance across all RCTs.
Limited evidence· Points toward a benefit
Acute Whole-Body Cryotherapy in screened non-professional athletes causes only mild HR (+5.85 bpm) and systolic BP (+3 mmHg) rises within normal range, with no adverse cardiac events; cardiovascular disease remains an absolute contraindication.

What complicates this
Safety only in screened healthy athletes; no therapeutic CV benefit shown; CVD is an absolute contraindication.
