Abstract
An apparatus for measuring calories consumed during sleep comprises determination means for determining a breathing/heartbeat oscillation, a body motion and an the intensity of the body motion, coefficient calculation means for calculating a coefficient which is a reference value for calculating calories consumed during sleep, based on the signals in a given period of breathing/heartbeat oscillation and a sleep metabolic rate, consumed calorie calculation means for calculating calories consumed during sleep, based on consumed calories according to the magnitude of each signal and the coefficient, and storage means for storing various arithmetic expressions in advance. Accordingly, the present apparatus makes it possible to acquire calories consumed by the motions of the body of an individual subject in more detail and to measure calories consumed during sleep more accurately.
