H-55 Evaluation of the Amenity based on the Air of 30% Oxygen Concentration : Part7 Evaluation of the Amenity in the case of bathing

Abstract

Effects on psychological and physiological characteristic by intake of high concentration oxygen while taking bubbling bath were studied. To keep oxygen concentration and water temperature, we employed water-heater with oxygen enrichment membrane unit. Using this device, high concentration oxygen (approx.30%) was supplied into bath water. As a result, it's effective for mind and body that intake high concentration oxygen and tended to control the increase of heartbeat.
