MENTAL AND PHYSICAL STATE INDUCEMENT DEVICE, MENTAL AND PHYSICAL STATE INDUCEMENT METHOD, AND STORAGE MEDIUM STORING CONTROL PROGRAM

The invention provides a mental and physical state inducement device (20), which includes a rhythm determination module (205) and a respiratory inducement control module (206). The rhythm determination module determines a target breathing rhythm for changing the target user's mental and physical state to the target mental and physical state. The breathing inducement control module controls the breathing inducement device (22) that stimulates the sense organs of the target person to perform breathing inducement so that the target person breathes according to the target breathing rhythm determined by the rhythm determination module. The rhythm determination module determines the target breathing rhythm to include not only the expiration period for exhalation and the inhalation period for inhalation, but also a grace period between the expiration period and the inhalation period. The grace period is a switching period between the expiration period and the inhalation period, and is a period during which exhalatio
