The Claim
In healthy individuals, cold-water immersion applied to either partial or whole-body regions likely results in a small reduction in creatine kinase levels (Hedges' g = –0.24) within 72 hours following exercise, indicating a modest attenuation of muscle damage biomarkers; however, this effect loses statistical significance after trim-and-fill adjustment, suggesting potential overestimation due to publication bias.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking cold baths or cold showers after working out might slightly lower a marker of muscle damage in healthy people, but the benefit could be smaller than studies suggest because of biased reporting.
See the scientific wording
Cold-water immersion (CWI) applied to either partial or whole-body regions likely reduces creatine kinase (CK) levels by a small magnitude (Hedges' g = –0.24) within 72 hours after exercise in healthy individuals, suggesting a modest attenuation of muscle damage biomarkers, though this effect may be overestimated due to publication bias as it loses significance after trim-and-fill adjustment.
What the research says
1 studyThe study looked at cold-water baths after exercise and found they slightly lower a marker of muscle damage, just like the claim says, and also warns the effect might look better than it really is because of biased reporting.
