Abstract

A toilet system includes: a toilet seat; a sensor configured to measure a physical quantity which reflects blood flow conditions of a user; a health index calculator configured to calculate a plurality of health indices based on measurement results of the sensor; a health index output part configured to output the plurality of health indices which has been calculated; a timer configured to measure a seating time; and a controller configured to control an output manner of the health index output part based on measurement results of the timer. When the seating time is not shorter than a first required time but shorter than a second required time, the first health index is outputted, but the second health index is stopped to be outputted. When the seating time is not shorter than the second required time, both the first health index and the second health index are outputted.
