1. A biological state guidance device comprising:
a biological state estimation unit configured to estimate a biological state of an occupant of a vehicle;
a target value decision unit configured to decide on a target value that is an index for setting the biological state of the occupant as a target state,
wherein the target value corresponds to a first alertness level;
a stimulus generation unit configured to control a stimulus generation device for generating a stimulus for guidance so that the biological state of the occupant is close to a target value on the basis of the estimated biological state and the target value; and
a position information detection unit configured to detect position information of the vehicle; and
a destination information acquisition unit configured to acquire destination information about a destination of the vehicle,
wherein the target value decision unit changes the target value of the biological state to a higher alertness level as a distance based on the destination information and on the position information decreases.
