<p>Disclosed is a physiological function rejuvenation device provided with an air-conditioning control unit (50) for running a temperature variation mode wherein the following are executed in alternation, at least once each: high-temperature holding behavior wherein the target temperature of an air-conditioning unit (20) is maintained at a high target temperature for a prescribed amount of time; and low-temperature holding behavior wherein the target temperature of the air-conditioning unit (20) is maintained at a low target temperature for a prescribed amount of time. In said temperature variation mode, when the high-temperature holding behavior or the low-temperature holding behavior finishes, the other is executed.</p>
