METHOD FOR PREDICTING FUTURE CHANGE IN PHYSICAL CONDITION OF PERSON FROM SLEEP-STATE HISTORY

A method includes: acquiring body motion data related to body motions of a target person; generating, based on the body motion data, sleep state data related to a sleep state of the target person; storing the sleep state data into a sleep state database; predicting a future change in a physical condition of the target person from the sleep state data by referencing a physical condition prediction information database; and when the physical condition data indicating the physical condition of the target person is acquired, reading past sleep state data over a past period from the sleep state database, collating the physical condition data with the past sleep state data to generate physical condition prediction information for predicting a particular change in the physical condition from particular sleep state data, and registering the physical condition prediction information into the physical condition prediction information database.
