As shown in (), even if the body movement level is below the judgment threshold, it has not been continuously below 3 minutes. In minutes, it is determined as an awakening state (white circle). In other words, the sleep state is determined more strictly before falling asleep, and if it exceeds the determination threshold even a little, it is determined as an awake state. This will prevent you from being mistakenly determined to be in a sleep state when you do not have a lot of physical movement such as reading or operating a computer on bedding such as a bed before going to sleep. it can.
- the sleep determination method is changed before and after falling asleep, so as shown in FIG. 5 above, the sleep determination result varies before and after falling asleep even at the same body movement level.
- the state is determined severely after waking up, and the state of wakefulness is determined rigorously, thereby reducing erroneous determinations due to noise and minute movements.

- the black part indicates the sleep state
- the broken line part indicates the bed leaving state.
- Fig. 6 and Fig. 7 above it is considered that the sleeper entered the switch almost immediately before falling asleep, from July 9th to 11th, 13th in Fig. 6, August 5th in Fig. 7, Since it is 6th and 8th, based on these data, the actual awakening time before going to sleep is compared with the result of the above sleep determination.
- the time determined to be awake relative to the time from bed entry to sleep (B-A) is about 30%, and is determined correctly.
- the sleep determination method according to the present invention while the ratio is low, the time determined to be arousal is about 65% of the actual awakening time, which is more than double that of the conventional method. Become. That is, FIG. 8 shows that the sleep determination method according to the present invention has higher determination accuracy than the conventional sleep determination method.
- the body motion signal accompanying the body motion of the sleeper falls below the determination threshold continuously for a predetermined time before falling asleep, it is determined that the patient is in a sleep state, and otherwise. It is determined that the person is awake. Therefore, compared to the conventional method of determining a state of wakefulness when the body motion signal exceeds the judgment threshold for a predetermined time, even if the sleeping person is moving with less body motion, such as reading before going to sleep or using a computer.
- the awake state can be detected with high accuracy without misjudging the sleep state.
- the sleep determination method is switched between before and after falling asleep. As long as this is the case, the same sleep determination method as before sleep may be used even after falling asleep. However, in this case, the probability of misjudgment as an arousal state increases due to the effects of noise after sleep.
- the body motion determination threshold is determined based on the body motion signal, and the force is updated as needed. This value is a fixed value determined in advance based on experiments and empirical rules. Also good.
- the sleep determination device (10) described above is adapted to use this force for a sleep capsule that performs air conditioning by following the sleep state of the sleeper, such as a force used for the health management of the sleeper.
- a measuring device can also be applied.
- the present invention is useful as a sleep determination device that determines a sleep state of a sleeper based on a body motion signal associated with the sleeper's body motion.
