What it is
Regulatory status: Recovery and cooling practice; not a medical device or treatment by default.
Evidence basis: Human clinical evidence
Cold-water immersion rapidly cools skin and superficial tissue, constricts blood vessels and changes nerve signaling and perceived soreness. Post-exercise studies suggest short-term recovery effects, but repeated use immediately after strength training may conflict with desired training adaptation.
