Hydrotherapy, formerly called hydropathy, is a part of medicine and alternative medicine, in particular of naturopathy, occupational therapy and physiotherapy, that involves the use of water for pain relief and treatment. The term encompasses a broad range of approaches and therapeutic methods that take advantage of the physical properties of water, such as temperature and pressure, for therapeutic purposes, to stimulate blood circulation and treat the symptoms of certain diseases.〔 Various therapies used in the present-day hydrotherapy employ water jets, underwater massage and mineral baths (e.g. balneotherapy, Iodine-Grine therapy, Kneipp treatments, Scotch hose, Swiss shower, thalassotherapy) and/or whirlpool bath, hot Roman bath, hot tub, Jacuzzi, cold plunge and mineral bath. ==Uses== Water therapy may be restricted to use in physical therapy, and as a cleansing agent. However, it is also used as a medium for delivery of heat and cold to the body, which has long been the basis for its application. Hydrotherapy involves a range of methods and techniques, many of which use water as a medium to facilitate thermoregulatory reactions for therapeutic benefit. Practitioners of hydrotherapy may seek use it to produce vasodilation and vasoconstriction.〔 These cause changes in blood flow and associated metabolic functions, via physiological mechanisms, including those of thermoregulation,〔 that are these days fairly well understood, and which underpin the contemporary use of hydrotherapy.〔〔 When removal of tissue is necessary for the treatment of wounds, hydrotherapy which performs selective mechanical debridement can be used. Examples of this include directed wound irrigation and therapeutic irrigation with suction.〔 It continues to be used as an adjunct to therapy, including in nursing, where its use is now long established.〔〔〔 It continues to be widely used for burn treatment,〔〔 although shower-based hydrotherapy techniques have been increasingly used in preference to full-immersion methods,〔 partly for the ease of cleaning the equipment and reducing infections due to contamination.〔 Hydrotherapy is used today in alternative medicine.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「hydrotherapy」の詳細全文を読む スポンサード リンク
