To provide an apparatus for promoting ineffective sweating includes an air heating unit for heating air in a sweating room, a mist generator for generating mist, a blower for circulating air in the sweating room by supplying mist, and a control device. The sweating room is provided with a temperature sensor and a humidity sensor for measuring temperature and relative humidity respectively in the sweating room. The control device is provided with a dew-point temperature determination unit for determining a dew-point temperature td in the sweating room based on the temperature and the relative humidity and a temperature setting unit for setting a body temperature of a user, and controls the air heating unit and the mist generator so that the dew-point temperature td is kept higher than the body temperature. This configuration can promote comfortable ineffective sweating with the low physical burden on the user.
