WBC-P1: Whole-Body Cryotherapy is an effective adjunct for chronic pain — Grade B Moderate
Moderate evidence· Points toward a benefit
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.
Studied in Adults with chronic musculoskeletal pain (adjunct to standard care)clinical studies
How strong the finding is
Evidence-based narrative review (Pain and Therapy 2021). Source: PMC8119547. Dossier claim id WBC-P1.
How it may work
Cold-induced analgesia (gate control, reduced nerve conduction) plus systemic anti-inflammatory effect.
What complicates this
Effect size varies by condition and protocol; adjunct only.
WBC-P2: Whole-Body Cryotherapy reduces fibromyalgia pain and improves QoL during treatment — Grade B Moderate
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
How strong the finding is
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.
How it may work
Central pain-perception modulation and systemic anti-inflammatory effect.
What complicates this
Pain relapses after cessation; ongoing maintenance appears necessary.
WBC-R2: Whole-Body Cryotherapy non-inferior to cold-water immersion for DOMS and jump performance — Grade B Moderate
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.
Studied in Athletes and active adultsclinical studies
How strong the finding is
Systematic review & meta-analysis, 13 RCTs, n=214 (2024–2025). Source: PMC12851776. Dossier claim id WBC-R2.
How it may work
Both cold modalities trigger vasoconstriction and analgesia; dry cold-air exposure achieves comparable recovery outcomes to immersion.
What complicates this
Head-to-head equivalence; some protocols favor CWI at earlier timepoints.
WBC-MD1: Whole-Body Cryotherapy as add-on reduces depression scores — Grade B Moderate
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.
Studied in Adults with depression (add-on to pharmacotherapy)clinical studies
How strong the finding is
RCT (Frontiers Psychiatry 2020) + systematic review/meta-analysis, 10 studies, n=294 (2021). Source: PMC7296110. Dossier claim id WBC-MD1.
How it may work
Norepinephrine surge, β-endorphin release, and BDNF elevation proposed for mood effect.
What complicates this
Add-on only; must not be positioned as standalone mental-health treatment.
WBC-AR1: Whole-Body Cryotherapy improves ankylosing spondylitis disease activity — Grade B Moderate
Moderate evidence· Points toward a benefit
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).
Studied in Adults with ankylosing spondylitis (adjunct to pharmacotherapy and exercise)clinical studies

How it may work
Systemic anti-inflammatory effect and analgesia reduce disease activity markers.
What complicates this
Protocol heterogeneity across studies (-60C to -110C).
WBC-R1: Whole-Body Cryotherapy improves countermovement-jump recovery 1–48h post-exercise — Grade B Moderate
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.
Studied in Athletes and active adultsclinical studies
How strong the finding is
Network meta-analysis, 51 RCTs, n=1,243 (Frontiers Sports & Active Living 2026). Source: PMC13137059. Dossier claim id WBC-R1.
How it may work
Peripheral vasoconstriction reduces edema and inflammatory-mediator influx; central fatigue and pain-perception modulation aid neuromuscular recovery.
What complicates this
DOMS reduction not significant immediately post-exercise; benefit concentrated on explosive-performance recovery.
WBC-I1: Whole-Body Cryotherapy reduces IL-1β and raises IL-10 — Grade B Moderate
Moderate evidence· Points toward a benefit
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.
Studied in Athletes; individuals with obesityclinical studies

Meta-analysis, 11 RCTs, n=274 (Scientific Reports 2025). Source: DOI 10.1038/s41598-025-90396-3. Dossier claim id WBC-I1.
How it may work
Cold-induced cytokine modulation: decreased pro-inflammatory IL-1β/IL-6/TNF-α, increased anti-inflammatory IL-10.
What complicates this
IL-6 and TNF-α reductions trended but did not reach significance across all RCTs.
WBC-CV1: Whole-Body Cryotherapy is cardiovascularly safe in screened athletes — Grade C Limited
Limited evidence· Points toward a benefit
In 10 non-professional middle-distance runners given three once-daily whole-body cryotherapy sessions under ECG and vital-sign monitoring, ECG intervals (PR, QT, QTc) did not change significantly, mean heart rate rose about 6 bpm (50.98 to 56.83 bpm) and systolic blood pressure about 3 mmHg (118 to 121 mmHg) after sessions, and respiratory rate and oxygen saturation were unchanged. This is short-term tolerability data in a very small group of trained runners; it does not establish safety in older, untrained or cardiovascular-risk members, for whom standard WBC cardiovascular contraindications still apply.
Studied in 10 non-professional trained middle-distance runners (3 WBC sessions)clinical studies
How strong the finding is
Prospective study, non-professional trained runners (Frontiers Cardiovascular Medicine 2022). Source: PMC9227663. Dossier claim id WBC-CV1.
How it may work
Transient cold-pressor sympathetic response within physiological limits.
What complicates this
Safety only in screened healthy athletes; no therapeutic CV benefit shown; CVD is an absolute contraindication.
