Further, the nap plan according to the present embodiment is updated in real time by the function of the update unit 50 while the subject is taking a nap. As described above, the intra-nap information is acquired while the subject is taking a nap. Here, a case is assumed in which, for example, the heartbeat, breathing, and body temperature of the subject are acquired as the intra-nap information. Note that, here, as the “heartbeat”, a heart rate per minute of the subject is acquired. Here, an average number of breaths per minute of the subject is acquired as the “breathing”.
By acquiring the intra-nap information described above while the subject is taking a nap, the nap environment determination system 1 can know, for example, that the sleep state of the subject who is taking the nap has switched or that the body temperature of the subject who is taking the nap has increased. The update unit 50 updates the nap plan, based on such intra-nap information.

The steps S1 to S3 are performed before a nap of the subject is started.
In step S4, a nap of the subject is started. Here, the nap environment determination system I adjusts the environment condition of the subject who takes the nap, based on the nap plan.
In step S5, the intra-nap information acquisition device 70 of the nap environment determination system 1 acquires intra-nap information while the subject is taking the nap and transmits the intra-nap information to the intra-nap information acquisition unit 20.
In step S6, the nap plan is updated by the update unit 50 of the nap environment determination system 1.

In the nap environment determination system 1 according to the present embodiment, the sleep state includes a wakeful state, a REM sleep state, a light sleep state, and a deep sleep state.
(6-9)
In the nap environment determination system 1 according to the present embodiment, the environment condition includes at least one of a thermal environment, a lighting environment, an intra-bedding thermal environment, a bedding position, and a sound environment, in the space in which the subject who is taking a nap is present.
(6-10)
The nap environment determination system 1 according to the present embodiment further includes the environment condition adjustment device 100 and the actuator 110. The environment condition adjustment device 100 is a device for adjusting the environment condition, based on the nap plan. The actuator 110 controls the environment condition adjustment device 100. The environment condition adjustment device 100 includes the air-conditioning apparatus 101 and the bedding 102 having a temperature adjustment unit.
The nap environment determination system 1 further includes the environment condition adjustment device 100 that is a device for adjusting the environment condition, based on the nap plan, and the actuator 110 that controls the environment condition adjustment device 100. According to this configuration, the environment condition can be adjusted by the environment condition adjustment device 100.
(7) Modifications
The embodiment described above can be appropriately modified as illustrated in the following modifications. Each modification may be applied in combination with another modification within a range such that no contradiction occurs. Note that the same configurations as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.
(7-1) Modification 1A
The nap environment determination system 1 according to the present disclosure may further include an output unit that outputs the nap plan. Alternatively, for example, the pre-nap information acquisition device 60 or the management apparatus 200 may have a function as the output unit.
In the nap environment determination system 1 according to the present modification, for example, the subject can check the nap plan immediately after being created by the creation unit 40, and a history of updates to the nap plan. Therefore, it is possible to easily confirm how the user's nap environment is determined.
(7-2) Modification 1B
The nap environment determination system 1 according to the present disclosure may create a report in which items related to the nap of the subject are described in detail. Hereinafter, such a report is referred to as a nap report. In addition, when the nap environment determination system 1 includes the output unit described in the modification 1A, the nap report may be outputted by the output unit. For example, the nap environment determination system 1 may create and output a nap report as illustrated in
As illustrated in
In the nap environment determination system 1 according to the present modification, for example, the subject can easily check his/her own biological information during a nap, a transition of his/her own sleep state, and the like.
(7-3) Modification 1C
While in the embodiment described above, the management apparatus 200 is described as being installed in a space different from the space RM, this is not a limitation. For example, the management apparatus 200 may be installed inside the space RM. In this case, the management apparatus 200 may perform, for example, short-range wireless communication with the pre-nap information acquisition device 60, the intra-nap information acquisition device and the environment condition adjustment device 100 to receive and transmit various data.
While the embodiments of the present disclosure have been described, it will be understood that various changes in form or details may be made therein without departing from the spirit and scope of the claims.
The present disclosure is not limited to the embodiments described above as they are. The present disclosure can he embodied by modifying its constituent elements without departing from the gist of the present disclosure in the implementation stage. In addition, the present disclosure can form various disclosures by appropriately combining a plurality of constituent elements disclosed in each of the embodiments described above. For example, some constituent elements may be deleted from all the constituent elements illustrated in the embodiments. Further, constituent elements may be appropriately combined in different embodiments. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all modifications apparent to those skilled in the art are intended to be included therein.
