Outline of Final Research Achievements

A toilet causes a household accident like a cardiac disease as well as a bathroom. This study aims to assess improvement of human physiological and psychological responses while using a toilet in which a fan heater device is operated in winter and a fan device in summer through a series of subjective experiments. It was not found out clearly that blood pressure rise caused by defecation was suppressed, when a fan heater device is operated in winter. It was found out clearly that thermal comfort while using a toilet was improved, when a fan heater is operated in winter and fan is operated in summer.
