Cold therapy for post-exercise muscle soreness
Evidence review
Overview
This entry covers recovery after strenuous exercise in healthy people, not a chronic medical condition, and is included for completeness. A Cochrane review of 17 small trials (366 participants) found cold-water immersion at 41-59 F, mostly 50-59 F, reduced muscle soreness at 24-96 hours compared with rest. Many later meta-analyses agree on short-term soreness reduction (for example SMD -0.81 across 52 studies, Jeon 2026; g -0.40 across 30 RCTs, Zhu 2026), though several analyses show signs of publication bias and the effect shrank or lost significance after adjustment, with smaller and inconsistent effects on strength and power, a transient drop in jump performance immediately after immersion, and no clear advantage of colder water. Umbrella reviews rate most of this evidence low or critically low in quality and highly overlapping. Regular post-exercise cold immersion blunted gains in muscle strength and mass during strength training.
Key findings
- Cochrane, 17 trials, 366 participants: soreness SMD -0.55 (95% CI -0.84 to -0.27) at 24 h, -0.66 at 48 h, -0.93 at 72 h vs passive rest; no difference vs contrast or warm water (Bleakley 2012).
- 52 studies of single-session immersion: DOMS SMD -0.81, creatine kinase SMD -0.64; about 41 F water was no better than 50-59 F (Jeon 2026).
- 30 RCTs vs seated rest: DOMS g -0.40 (95% CI -0.64 to -0.16) and CK g -0.24, but CK lost significance after publication-bias adjustment and DOMS shrank to g -0.172; no effect on jump or isometric strength; partial immersion impaired immediate jump power (Zhu 2026).
- 22 RCTs vs passive recovery: soreness g -0.58 overall, but not significant after accounting for within-study dependency (g -0.363, 95% CI -0.842 to 0.115) (Zhu 2026).
- 32 RCTs: cold therapy reduced DOMS pain within 24 h (SMD -0.57), not beyond; heat also reduced pain, with no significant difference between cold and heat (Wang 2021).
- Umbrella review of 15 meta-analyses: quality low to critically low; soreness reduced up to 96 h, but strength and hypertrophy gains impaired with chronic use (Berjisian 2026).
- 12-week RCT, 21 men: post-exercise cold-water immersion blunted strength and muscle mass gains vs active recovery (Roberts 2015).
- Whole-body cryotherapy (cryo chamber) Cochrane: insufficient evidence; very low quality (Costello 2015).

- What
- post-exercise cold-water immersion
- Measured
- soreness, performance, inflammatory markers
- Result

- Who
- Physically active men in 12-week strength training (24 randomized, 21 analysed; 3 withdrew for unrelated injuries) plus a 9-man biopsy study

Can Water Temperature and Immersion Time Influence the Effect of Cold Water Immersion on Muscle Soreness? A Systematic Review and Meta-Analysis.
Machado AF et al. Sports Med. 2016. PubMed 26581833 · DOI · Free full text
- Who
- 9 RCTs (169 participants, 141 men) comparing CWI with passive recovery
- What
- CWI at various temperatures and durations
- Protocol
- 52-59 °F · 11-15 min
- Measured
- muscle soreness
- Result
- CWI was slightly better than passive recovery for immediate (MD 0.290, 95% CI 0.037-0.543) and delayed soreness (MD 0.315, 0.048-0.581); best results at 52-59 F (11-15 C) and 11-15 min, while 41-50 F (5-10 C) water and 5-10 min immersion were not significant; the one trial with immersion longer than 15 min was worse than passive recovery for delayed soreness (MD -2.200, 95% CI -4.169 to -0.231).
- Limitations
- Nine small trials, six of poor quality (mean PEDro 4.2); blinding often impossible; small effect.
Cooling and performance recovery of trained athletes: a meta-analytical review.
Poppendieck W et al. Int J Sports Physiol Perform. 2013. PubMed 23434565 · DOI
- Who
- 21 RCTs in trained athletes
- What
- post-exercise cooling (CWI, cryochambers, cold packs)
- Measured
- performance recovery
- Result
- Average effect of cooling was small (2.4%, g 0.28); CWI g 0.34, cryochambers g 0.25, cold packs g -0.07; whole-body immersion more effective than limb-only (g 0.62 vs 0.10).
- Limitations
- performance outcomes, not soreness
Protocols used in the studies
Trials immersed participants after exercise in water at or below about 59-68 F, most often 10-15 minutes at 41-59 F (in the Cochrane review just over 75% of trials used 50-59 F, with continuous immersion of 5-24 minutes, mean 12.6), usually as a single session after a damaging bout of exercise. Reviews most often favored 11-15 minutes at 52-59 F (Machado 2016) or 10-15 minutes at 41-59 F (Berjisian 2026); colder water (about 41 F) was not more effective (Jeon 2026), and immersion longer than 15 minutes showed no delayed benefit (Batista 2023) or was worse than passive recovery in one trial (Machado 2016).
What is still unknown
Clinical importance of the soreness reduction; whether benefits exceed placebo, heat or warm water; effects in patients undergoing rehabilitation for diagnosed musculoskeletal conditions (not studied as cold plunge); trade-off with training adaptation; publication bias in the many overlapping meta-analyses.
Safety
Cautions for cold therapy in this condition
- Routine post-training cold immersion may blunt long-term strength and hypertrophy gains (Roberts 2015, PMID 26174323: muscle mass +103 vs +309 g with active recovery; Berjisian 2026, PMID 42816732); passive recovery ranked best for strength-focused training (PMID 41845491).
- Immersion transiently reduces jump and sprint performance in the first hours afterwards (PMIDs 42473449, 41716304, 36862831, 36744038).
- Most trials did not actively monitor adverse events (Bleakley 2012, PMID 22336838; Costello 2015, PMID 26383887), so short- and long-term safety in these trials is largely unknown.

For clinicians
Suggested rationale
Cold-water immersion modestly reduces short-term soreness after strenuous exercise in healthy people (Bleakley 2012; Jeon 2026), but this is athletic recovery of a self-limited condition rather than treatment of a diagnosed disease, and on its own is unlikely to establish medical necessity.
