1. An arousal level prediction apparatus comprising:
a first obtaining unit that obtains, via a first sensor, first biological information of a user indicating current biological information regarding the user detected by the first sensor;
a second obtaining unit that obtains, via a second sensor, first environment information indicating a current environment around the user detected by the second sensor; and
a processor that
calculates, at a first time point, a first arousal level indicating a current arousal level of the user based on the first biological information,
predicts, at a second time point that is a certain period of time later than the first time point, a second arousal level, which is an arousal level of the user at the second time point, based on the first arousal level and the first environment information, and
outputs the second arousal level.
