Cold plunge
Not establishedWhy it might help
There is no proposed mechanism by which cold-water immersion clears a fungal, bacterial or viral skin infection. It is listed here because it is one of the most common questions mat athletes ask when they have been told to stop training.
What the research shows
No recovery modality treats these infections, and communal cold water is a shared-surface question rather than a therapeutic one. The literature on contact-sport infections places responsibility on excluding athletes with lesions and on hygiene, and one study cited in that review found Staphylococcus aureus in therapeutic whirlpools in college athletic training rooms. Cleveland Clinic separately notes that the fungus behind ringworm thrives in warm, humid environments such as locker rooms and can persist on skin and surfaces for months. Stay out of shared tubs with an open or undiagnosed lesion and see a clinician.

Infectious Disease in Contact Sports — PMC / Sports Health, 2018
Clinical review reporting about 20% of wrestlers lose practice or competition time to skin infections each year, with herpes gladiatorum affecting 20-40% of collegiate wrestlers and tinea corporis 60% of collegiate wrestlers per season. States transmission is almost exclusively skin-to-skin and that mats and other fomites are only minor vectors. Summarises NCAA and NFHS exclusion rules, including that active herpes lesions may not simply be covered to allow participation.
Ringworm (Tinea Corporis): What It Looks Like, Causes & Treatment — Cleveland Clinic
Condition overview: a highly contagious fungal infection producing a ring-shaped, scaly plaque with a raised border, appearing roughly 4 to 14 days after exposure. Spreads by skin-to-skin contact, contaminated surfaces and shared items such as towels, thrives in warm humid environments like locker rooms, and the fungus can persist on skin and surfaces for months. Advises shower shoes in communal areas, changing out of damp clothing and drying skin thoroughly.
