A plunge bath is a type of bath that involves submerging oneself in cold water for therapeutic or invigorating purposes. Some synonyms for plunge bath include cold bath, ice bath, and plunge pool. These terms are often used interchangeably and refer to the same type of bathing experience. Although plunge baths may seem intimidating at first, they can offer a range of benefits such as improved circulation, reduced inflammation, and increased energy levels. Many athletes, particularly swimmers and endurance athletes, use plunge baths as part of their recovery routine, while others simply enjoy the invigorating sensation of a cold dip.
