Abstract: A heating and cooling stimulation device includes a stimulation supply unit configured to supply hot stimulation and cold stimulation to a subject; an estimation unit configured to estimate a fatigue level of the subject; and a control unit configured to control an operation of the stimulation supply unit so as to supply the hot stimulation and the cold stimulation alternately to the subject in accordance with the fatigue level estimated by the estimation unit. The control unit controls the operation of the stimulation supply unit such that an amount of the cold stimulation received by the subject increases as the fatigue level estimated by the estimation unit becomes higher.
