PROBLEM TO BE SOLVED: To provide a private low-temperature sauna which gives immunity to the human body (somatid) and facilitates sweating.SOLUTION: Negative ion ores 8 and a negative ion generating pump 10 are connected by an air pipe. By applying air pressure to the ores, a large amount of negative ions good for the human body is generated. The negative ions are mixed with warm water under a seat 7, and a room is filled with negative ions. The negative ions are absorbed through respiration, the mouth, the nose, the skin or the like. Immunity of the human body (somatid) is thus improved and sweating is facilitated at a low temperature.COPYRIGHT: (C)2012,JPO&INPIT【課題】人体の(ソマチット)に免疫力を与えて発汗できる個室低温サウナを提供する。【解決手段】マイナスイオン鉱石8にマイナスイオン発生ポンプ10から、エアーの配管が接続、鉱石にエアーの圧力を与えて、人体に良い多量のマイナスイオンが発生できる。腰掛7の下で温熱湯と中和されて、室内にマイナスイオが充満され、呼吸・口・鼻・皮膚、等から吸収されて人体の(ソマチット)に免疫力がつき、低温で発汗できるサウナ装置。【選択図】図1
