Patent ID: 8454490

Claim:
A biological rhythm adjustment device comprising: an information input unit receiving a moving schedule, and biological information on a subject that moves in accordance with said moving schedule; and a block setting a sleeping schedule for said subject based on said moving schedule and said biological information, the block including a parameter-setting unit for generating parameters based on said moving schedule and said biological information, and a sleep/arousal inducing unit setting said sleeping schedule with said parameters, said sleep/arousal inducing unit including a device raising a body temperature of said subject and a device relaxing said subject, the block inducing sleep of said subject for a first time period/a second time period correspondingly to an eastward route/a westward route of said moving schedule, respectively, said first time period being shorter than said second time period, the block reducing the body temperature of said subject to induce sleep of said subject for the eastward route, and the block reducing sleep pressure of said subject prior to inducing sleep of said subject for the westward route, the block reducing the ambient temperature around said subject to induce sleep of said subject for the eastward route, the block performing a relaxation event, then a body-temperature raising event to induce sleep and performing irradiation of high-illuminance light to induce waking of said subject for the westward route, the device relaxing said subject being set to initiate a relaxation event at a first time for the eastward route that is after a time at which the device raising the body temperature is set to initiate a body-temperature raising event, and the device relaxing said subject being set to initiate the relaxation event at a second time for the westward route that is before a time at which the device raising the body temperature is set to initiate the body-temperature raising event.
