The Study
Effects of cold-water immersion at different body regions on post-exercise muscle damage recovery: a systematic review and meta-analysis
This study is like a super-summary of 30 fair experiments where some people got cold-water baths after exercise and others just sat and rested. Because it combines real experiments, it can tell us that cold water probably helps with soreness and muscle damage markers, but it doesn’t prove it 100% because people knew which group they were in.
Analysis score
Maximum 100 for a systematic review with meta-analysis.
Where the score came from
Putting your body in cold water after exercise can help you feel less sore and lower a marker of muscle damage, but it doesn’t make your muscles stronger right away and can hurt jumping power right after.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Feeling less sore is helpful for comfort and next-day recovery, but the drop in jump performance means athletes should avoid cold water if they need to perform explosive movements soon after.
- 2Cold water reduced muscle soreness by 0.40 and muscle damage marker (CK) by 0.24 on a scale called Hedges’ g.
- 3It didn’t help muscle strength (0.08) and hurt jump performance right after (-0.94 for partial immersion).

Taking a cold-water bath after exercise probably helps reduce muscle soreness, especially in the first day, and the effect seems real even when accounting for biased studies.
You don’t need to dunk your whole body in cold water after a workout—just cooling the sore muscles works just as well for recovery.
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.
Taking a cold-water plunge after exercise might make your jumping power worse right afterward, especially if only part of your body is in the water — but soaking your whole body doesn’t seem to have much of an effect.
Taking cold baths or cold plunges after exercise might make you *feel* better, but it doesn’t actually help your muscles get stronger faster in the first 72 hours.
Taking cold water baths after working out might make your muscles feel less sore, but it won’t help you recover faster and could actually slow muscle growth by blocking the body’s natural healing response.
