Cold exposure

Cold-water immersion reduces muscle soreness fairly consistently. It also appears to blunt some of the muscle-size and strength gains from resistance training when used straight after a session, which is the opposite of what most people take it for. The metabolic, immune and mood claims rest on small, short studies.

How this list was built

We searched Europe PMC for English-language papers published since 2012 whose title contains “cold water immersion” or “cold-water immersion” or “cold exposure” or “cold plunge” or “whole-body cryotherapy” or “winter swimming”, kept meta-analyses, systematic reviews and trials, including non-randomised ones, because strong evidence on this topic is scarce, then ranked them by study design first, then recency and citations. Retracted papers are removed.
