How strong is the evidence for Cold Exposure?

Meta-analyses consistently find cold water immersion reduces delayed-onset muscle soreness and modestly improves perceived recovery after strenuous exercise, with effects present across team-sport and endurance contexts and influenced by water temperature and immersion duration. That evidence is currently rated moderate (59/100), built on 11 published studies, including 1 randomized controlled trial and 7 meta-analyses -- a reasonable base, but not yet enough for full certainty.
