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.

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.

Quantitative
1 study reviewed
In plain English

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 study
  1. Study: Effects of cold-water immersion at different body regions on post-exercise muscle damage recovery: a systematic review and meta-analysis

    The 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.
