Bathing is the immersion of the body, wholly or partially, in a medium, usually a liquid or heated air. It may be for personal hygiene, religious ritual, or therapeutic purposes. By analogy, especially as a recreational activity, the term is also applied to sun bathing and sea bathing.
People bathe at a range of temperatures, according to custom or purpose, from very cold to very hot. In the western world, bathing is usually done at comfortable temperatures in a bathtub or shower. This type of bathing is done more or less daily for hygiene purposes, although it has been claimed that hot-air bathing is a more effective body cleanser than water.[1] A ritual religious bath is sometimes referred to as immersion or baptism. The use of water for therapeutic purposes can be called a water treatment or hydrotherapy. Recreational water activities are also known as swimming and paddling.
