Abstract: An illumination control method includes: causing an illumination apparatus to illuminate a predetermined space with light; and controlling at least one of a color temperature of light which the illumination apparatus emits and an illuminance of the light which the illumination apparatus emits in the predetermined space, to cause an integrated value to be at least 10 μW·h/cm2. The integrated value is a value resulting from integrating time and an effective amount of melatonin during a first time frame from 5:00 to 14:00.
