Cold-Water Immersion
Ten to fifteen minutes at 10 to 15 °C after training when soreness matters more than adaptation: one way to carry out what the review summary this entry was written from reports: that cold-water immersion reliably reduces soreness, does less for performance, and may blunt muscle growth if used routinely.
Never immerse alone.
- Cardiovascular, vascular or clotting conditions: see a clinician before use
- Numbness, skin discolouration or pain during immersion: stop and seek advice
How to do it
What the evidence says
This practice is one way to carry out what the sources on the concept entry (phys.recovery.recovery-and-adaptation-tradeoff) studied: cold-water immersion after exercise, for soreness, muscle-damage markers, performance and adaptation. Machado 2015 (meta-analysis) reports cold-water immersion more effective than passive recovery for immediate and delayed soreness, with 10 to 15 °C water and 10 to 15 minutes of immersion giving the largest effects; Zhu 2026 (meta-analysis) reports lower creatine kinase and soreness with no benefit for jump height or maximal strength; Patel 2025 (systematic review) reports consistent reductions in soreness and muscle-damage markers within 24 to 48 hours, with mixed effects on neuromuscular performance; Poręba 2025 (systematic review) reports that regular use in hypertrophy-focused resistance training may reduce muscle growth and type II fibre adaptations. The full account, source by source, is on the concept entry this practice links to (phys.recovery.recovery-and-adaptation-tradeoff).
- Misconception: 'Colder and longer is better.' Machado 2015 reports 10 to 15 °C water and 10 to 15 minutes of immersion as optimal for soreness.
- Misconception: 'It speeds up recovery of strength and power.' Soreness improves; performance outcomes are frequently null.
- Does not treat injury
- Does not accelerate healing of muscle damage, only the perception of soreness

Each source below is shown with its study design and a link to the original study, or, where it is not a completed research paper, with what kind of record it is; those are not counted. This is the audit trail.
Why do some records show a record type instead of a study design?
A study design is shown for a completed, peer-reviewed paper. A registered protocol, a preprint, a conference abstract, a referee report or a book chapter has not been through peer review as a finished paper, so it is labelled for what it is, and it is counted in no source count. Where a record could not be confirmed as a completed paper at all, it says so rather than guessing. They all stay in the list, and their DOI still resolves, because the count of what was screened is part of the audit trail.
- Protocol / registration A registered plan for a review or trial, not its results.
- Preprint Posted by its authors before peer review.
- Conference abstract A conference summary rather than a peer-reviewed paper.
- Peer-review report A referee's report on a paper, not the paper itself.
- Guideline / position stand A recommendation derived from evidence, which is a step further from the data than the evidence itself.
- Book chapter A chapter in a scholarly book rather than a journal paper.
- Type not recorded Our record does not say what kind of publication this is, so it is counted in no source count. That is a gap in our data, not a judgement about the research.
“Abstract only” means the review read that paper’s abstract, not its full text; “screened only” means it was included at re-screening and not extracted. Both stay in the trail with their DOI, because how a source was read is part of the audit.
