It is equipped with an advice providing unit 9 that provides information.

Here, the comfortable sleep living environment support system 1 is a system for supporting the user so as to obtain a living environment in which a good sleep (comfortable sleep) can be obtained. The sound sleep living environment support system 1 is composed of, for example, a computer on which software for sound sleep living environment support is installed. As the software for supporting a comfortable sleeping environment, for example, software equipped with AI (artificial intelligence) technology can be used. AI is equipped with an AI engine that has been trained with optimal teacher data.

The user is a resident of a house equipped with a good sleep living environment support system 1.

The sleep state 2 will be described later.

The sleep measurement unit 3 can be configured as, for example, a functional block of software for supporting a comfortable sleeping environment. The sleep measurement unit 3 measures the data of the sleep state 2 by using, for example, a wearable multifunctional terminal such as a smart watch as the sleep measurement means 11. A wearable multifunctional terminal such as a smart watch has various functions such as a sphygmomanometer, a heart rate monitor, a pedometer, an activity meter, and a sleep measurement in addition to the timekeeping function. Therefore, the sleep measurement unit 3 Can be used as. A wearable multifunctional terminal such as a smart watch can perform sleep measurement by detecting the body movement of a user during sleep using, for example, a built-in accelerometer or the like. The measured data of the sleep state 2 may be recorded in the storage unit 12. For example, the storage unit 12 can use a memory (internal memory) provided in the comfortable sleep living environment support system 1 or a memory (external memory) connected to the outside of the comfortable sleep living environment support system 1. However, the sleep measuring means 11 is not limited to a wearable multifunctional terminal such as a smart watch.

The living environment is a sleep-related environment such as a house or a bedroom. The living environment will be described later. The living environment data 4 is data related to the living environment. The living environment data 4 will be described later.

The living environment measurement unit 5 can be configured as, for example, a functional block of software for supporting a comfortable sleeping environment. The living environment measurement unit 5 measures the living environment data 4 by using a living environment measuring means such as a living environment sensor 13, and records the living environment data 4 in the storage unit 12. The living environment sensor 13 may be used in any way as long as the necessary living environment data 4 can be measured.

The subjective data 6 is the user's subjective data regarding sleep. The subjective data 6 can be, for example, a feeling of satisfaction with sleep, a degree of satisfaction with the living environment, a request, and the like. The acquired subjective data 6 can be recorded in the storage unit 12.

The subjective data acquisition unit 7 can be configured as, for example, a functional block of software for supporting a comfortable sleeping environment. The subjective data acquisition unit 7 uses, for example, a multifunctional terminal such as a tablet equipped with a chatbot function or a subjective data acquisition means 14 such as an AI speaker, and by, for example, a dialogue (or an interactive method) with a user. Acquire subjective data 6. Dialogue with the user can be performed while learning based on a predetermined scenario or the like.

Advice 8 includes various things such as those generally given to users and those given in special circumstances. Advice 8 broadly includes those that are directly related to sleep, those that are indirectly related to sleep such as diet, exercise, health, and sunbathing recommendations, and others. Advice 8 will be described later. The advice 8 can be provided regularly, for example, in the morning or at night, together with the acquisition of the subjective data 6. The advice 8 provided can be recorded in the storage unit 12.

The advice providing unit 9 has a function of processing data of the sleep state 2, living environment data 4, subjective data 6, and the like to create advice 8 for a good night's sleep, and other functions. The advice providing unit 9 can be configured as, for example, a functional block of software for supporting a comfortable sleeping environment. The advice providing unit 9 provides the user with advice 8 for a good night's sleep by using, for example, a multifunctional terminal such as a tablet or an advice providing means 15 such as an AI speaker. As the advice providing means 15, the same one as the subjective data acquisition means 14 may be used, or a different one may be used.

(2) The sleep measurement unit 3 may measure (at least one or more) sleep indexes such as sleep regularity, sleep efficiency, and sleep onset latency as the sleep state 2.

Here, sleep regularity is a sleep index as to whether or not sleep is performed regularly. Sleep regularity can be obtained by measuring and recording daily wake-up time and bedtime.

Sleep efficiency is a sleep index of whether or not sleep is being performed efficiently. Sleep efficiency is expressed as the ratio of sleep time to bedtime. The bedtime is the time from sleeping to waking up, and can be obtained from the data of the waking time and the bedtime. Sleep time is the time you actually slept. Causes of deterioration in sleep efficiency include, for example, awakening during sleep. Therefore, the sleep time can be set as the bedtime minus the awakening time on the way. The presence / absence, number of times, and time of awakening on the way can be obtained by measuring the body movement of the sleeping user by, for example, the sleep measuring means 11.

Sleep onset latency is the time required from wakefulness to falling asleep (time to fall asleep). Sleep onset latency can be obtained by measuring the body movements of the sleeping user with the sleep measuring means 11.

The sleep index is an index for judging sleep state 2, and the above-mentioned sleep regularity, sleep efficiency (midway awakening), and sleep onset latency are currently regarded as the most academically important sleep indexes. Is what you are doing. These sleep indexes can be obtained by measuring the wake-up time, the bedtime, the body movement of the sleeping user, and the like as described above. The wake-up time, bedtime, and body movement of the user during sleep can be obtained by wearing the above-mentioned sleep measuring means 11 (wearable multifunctional terminal such as a smart watch) and going to bed. In addition, these sleep indexes can also be obtained from subjective data 6 and the like.

(3) The living environment measurement unit 5 may measure (at least one or more) of room temperature, floor temperature, humidity, illuminance, color temperature, etc., which affect sleep, as living environment data 4 over time. good.

Here, the room temperature is the air temperature in the house (for example, the whole house or the living room, etc., and so on) or in the bedroom.
The floor temperature is the temperature of the floor in a house or bedroom (floor temperature, floor temperature).
Humidity is the humidity in a house or bedroom.
Illuminance is the brightness of lighting in a house or bedroom.
Color temperature is the color tone of lighting in a house or bedroom.
With time means to measure changes in room temperature, floor temperature, humidity, illuminance, color temperature, etc. over time. Therefore, the above-mentioned living environment sensor 13 includes a room temperature sensor, a floor temperature sensor, a humidity sensor, an illuminance sensor, a color temperature sensor, and the like that can detect room temperature, floor temperature, humidity, illuminance, color temperature, and the like. A timer that can measure the time is used. Since the time measurement function is used in the entire sound sleep living environment support system 1, the timer provided in the sound sleep living environment support system 1 may be used jointly and uniformly, or the timer for measuring the time may be used in a unified manner. Those provided in each part of the living environment support system 1 may be used individually.

(4) The advice providing unit 9 determines a sleep pattern from the sleep state 2, creates the first advice 8a in consideration of the determined sleep pattern and the living environment data 4, and also creates the first advice 8a.
The control signal 23 may be sent to the control unit 22 of the living environment adjusting device 21 so that the living environment based on the first advice 8a can be obtained.

Here, the advice providing unit 9 has at least a sleep pattern determining unit for determining a sleep pattern (sleep pattern), an advice creating unit for creating advice 8 such as the first advice 8a, and a living environment. It has a control signal generating unit for sending the control signal 23 to the control unit 22 of the adjusting device 21.

The sleep patterns are, for example, 1. Good sleep, 2. Light sleep, 3. Difficult to fall asleep 4. (Sleep) is shallow and it is difficult to fall asleep. Irregular, 6. Irregular midway awakening, 7. Difficult to fall asleep irregularly, 8. It can be classified into 8 stages, such as irregular sleep and light sleep, which makes it difficult to fall asleep. Of these, 1 to 4 are regular sleeps and 5 to 8 are irregular sleeps. And 1 is good sleep and 2-8 is problematic sleep.

Specifically, these eight sleep patterns are, for example, the presence or absence of regularity in the above-mentioned sleep regularity, the value of sleep efficiency (for example, 85% or more or less than 85%), and the value of sleep onset latency. It can be classified based on the contents and results of three types of sleep indicators (for example, less than 5 minutes or more than 5 minutes). However, the specific values of sleep efficiency and sleep onset latency are not limited to this.

For example, when sleep regularity: yes (regular), sleep efficiency: 85% or more, sleep onset latency: less than 5 minutes (short), the sleep pattern is 1. Get a good night's sleep.
If sleep regularity: Yes (regular), sleep efficiency: less than 85%, sleep onset latency: less than 5 minutes (short), the sleep pattern is 2. Sleep lightly.
When sleep regularity: Yes (regular), sleep efficiency: 85% or more, sleep onset latency: 5 minutes or more (long), the sleep pattern is 3. It becomes difficult to fall asleep.
If sleep regularity: Yes (regular), sleep efficiency: less than 85%, sleep onset latency: 5 minutes or more (long), the sleep pattern is 4. It becomes shallow and difficult to fall asleep.

In addition, when sleep regularity: none (irregular), sleep efficiency: 85% or more, sleep onset latency: less than 5 minutes (short), the sleep pattern is 5. It becomes irregular.
When sleep regularity: none (irregular), sleep efficiency: less than 85%, sleep onset latency: less than 5 minutes (short), the sleep pattern is 6. Awakens on the way irregularly.
When sleep regularity: none (irregular), sleep efficiency: 85% or more, sleep onset latency: 5 minutes or more (long), the sleep pattern is 7. It becomes difficult to fall asleep irregularly.
When sleep regularity: none (irregular), sleep efficiency: less than 85%, sleep onset latency: 5 minutes or more (long), the sleep pattern is 8. Irregular sleep makes it difficult to fall asleep.

Then, it is preferable to give a score to each of the sleep patterns 1 to 8 so that the sleep pattern can be objectively evaluated by the score. For example, 1 can be 0 points, 2, 3 can be -1 point, 4, 5 can be -2 points, 6, 7 can be -3 points, 8 can be -4 points, and the like. In this case, the closer to 0 points, the better the sleep quality, and the more negative points, the worse the sleep quality. However, the method of quantifying the sleep pattern is not limited to the above.

The first advice 8a is a general initial proposal for improving the living environment, etc., which the sound sleep living environment support system 1 makes to the user.

The first advice 8a is, for example,
1. 1. In the case of a good night's sleep, the status quo can be maintained because it can be left as it is.
2. In the case of light sleep, in order to deepen sleep, the deep temperature rises by moderate exercise and bathing, and so on.
3. 3. If it is difficult to fall asleep, it is necessary to eliminate the cold before going to bed and to make it darker and brighter in the morning two hours before going to bed in order to create an environment for sleeping.
4. If it is difficult to fall asleep lightly, to deepen the sleeping environment and sleep, eliminate the cold before going to bed and 2 hours before going to bed. And so on.
In the case of 5, 6, 7, and 8 irregularities, the room is darkened and brightened at a fixed time in order to ensure regularity.

The living environment adjusting device 21 is a device for adjusting the living environment. The living environment adjusting device 21 includes, for example, an air conditioner (air conditioner or the like), a floor heating device, a lighting device, and other devices.

An air conditioner is a device for adjusting room temperature (temperature of indoor air), humidity, and the like. The air conditioner includes an air conditioner for the entire building, an air conditioner for each layer, and an air conditioner for each room. The floor heating device is a device for adjusting the floor temperature. The floor heating device may be separate from or integrated with the air conditioner. A lighting device is a device that can adjust lighting on / off, illuminance of lighting, color temperature of lighting, and the like.

These living environment adjusting devices 21 mainly adjust the living environment such as thermal and light environments. The thermal / light environment is room temperature, floor temperature, humidity, illuminance, color temperature, and the like. These living environment adjusting devices 21 may be provided as individual devices, or may be configured as a unified device. As the living environment sensor 13 for measuring room temperature, floor temperature, humidity, illuminance, color temperature, etc., an air conditioner, a floor heater, a lighting device, or the like can be used, or these can be used. Can be used differently from.

The other living environment adjusting device 21 can include, for example, a humidifier, an aroma generating device, an audio device, an alarm device (alarm timer), and the like. The other living environment adjusting device 21 makes it possible to adjust the living environment other than the thermal / light environment and provide services.

The control unit 22 is a device for individually or centrally controlling a living environment adjusting device 21 such as an air conditioner, a floor heating device, a lighting device, and other devices.

The control signal 23 is a command signal sent from the advice providing unit 9 to the control unit 22. The control signal 23 gives instructions regarding control of the thermal / light environment necessary for comfortable sleep, provision of other living environments and services, and the like. The control signal 23 controls the living environment adjusting device 21 and the like for sleep on the spot and sleep on the next day or later.

(5) The advice providing department 9
When the subjective data 6 from the subjective data acquisition unit 7 is dissatisfied,
In light of living environment data 4,
When there is a problem in the living environment, advice 8b is created to improve the living environment, and a control signal 23 is sent to the control unit 22 of the living environment adjusting device 21 so that the living environment based on the advice 8b can be obtained. Send,
If there is no problem with the living environment, information and services for relaxing may be provided.

Here, the user's dissatisfaction in the subjective data 6 includes subjective items such as "light sleep", "difficult to fall asleep", and "has awakening on the way".

This advice 8b is a special recommendation made when the user is dissatisfied with sleep. Advice 8b includes specific recommendations for improving the living environment to eliminate user dissatisfaction.

The living environment adjusting device 21 can adjust the thermal / light environment and other living environments in response to the living environment problem.

Relaxation is, for example, a coping method for relieving stress. Information and services for relaxing include, for example, the provision of information such as bathing methods and the provision of services such as aroma and music. If necessary, the advice providing unit 9 can also send a control signal 23 to, for example, an aroma generator, an audio device, an alarm device, or the like to operate them.

(6) The advice providing department 9
If the data of the sleep state 2 from the sleep measurement unit 3 shows a deviation in the sleep rhythm, advice 8c for eliminating the deviation in the sleep rhythm is given, and at the same time, advice 8c is given.
A control signal 23 may be sent to the control unit 22 of the living environment adjusting device 21 to perform thermal light control for correcting the deviation of the sleep rhythm.

Here, the sleep rhythm is, for example, a state of change in which deep sleep and light sleep occur alternately during sleep, and a state of change in which non-REM sleep and REM sleep occur alternately during sleep.

The deviation of the sleep rhythm is that the sleep rhythm is not in an ideal state. In order to obtain an ideal sleep rhythm, for example, it is important that deep non-rem sleep occurs in the early stage of sleep onset.

This advice 8c is a proposal or suggestion that is specially made when there is a deviation in the sleep rhythm. Advice 8c includes specific recommendations for improving the living environment to eliminate the deviation of sleep rhythm.

The thermal light control for correcting the deviation of the sleep rhythm by the living environment adjusting device 21 is, for example, from 2 hours before the sleep onset time before the sleep rhythm shift so as to be the sleep onset time before the sleep rhythm shift. The lighting is at least one of low light, low color temperature, slightly higher room temperature, and floor temperature, which makes it possible to create an environment in which it is physiologically easy to fall asleep.

(7) The subjective data acquisition unit 7
Acquire subjective data 6 when waking up in the morning, grasp satisfaction with the living environment, requests, etc. (at least one of them),
The advice providing unit 9 modifies the first advice 8a and creates the second advice 8d that seems to be optimal (for the user) based on the satisfaction level and the request for the living environment grasped by the subjective data 6. You may.

Here, the subjective data 6 at the time of waking up in the morning includes the degree of sleep satisfaction immediately after waking up and the degree of satisfaction with the living environment of the night.

The satisfaction level and request for the living environment grasped by the subjective data acquisition unit 7 are the user's subjective satisfaction level and request for sleep that night.

The second advice 8d is a modification of the first advice 8a based on the subjective data 6, and is a more optimized and more specific proposal for the user.

(8) The sleep measurement unit 3
As a judgment of sleep regularity, measure at least one of the weekday-holiday deviation and the continuous deviation on weekdays.
The advice providing unit 9 gives advice 8e for eliminating the deviation based on the deviation of the sleep regularity measured by the sleep measuring unit 3, and also provides advice 8e.
A control signal 23 may be sent to the control unit 22 of the living environment adjusting device 21 to control the living environment.

Here, the difference between weekdays and holidays means that there is a difference in sleep time between weekdays and holidays. For example, the difference between the weekday and the holiday can be determined by the fact that the average wake-up time and the average bedtime are different by 2 hours or more or 20% or more between the weekday and the holiday.

A continuous shift on weekdays means that a shift in sleep time can be seen continuously even on weekdays. For example, the average wake-up time and average bedtime for several days (for example, 3 days or more) on weekdays, and the average value for the next few days (for example, about 2 to 3 days), wake-up time and bedtime for each day. Since the time is off by 20% or more, it can be considered as a continuous shift on weekdays.

However, the definition and contents of the weekday-holiday deviation and the continuous deviation on weekdays are not necessarily limited to the above. It may be configured so that it can be set / changed freely or arbitrarily according to the situation.

This advice 8e is a recommendation made specially when there is a deviation in sleep regularity. Advice 8e includes specific recommendations for improving the living environment to eliminate the deviation of sleep regularity.

The control of the living environment includes the control of thermal light by the living environment adjusting device 21.

<Action> The action of this example will be described below.

FIG. 2 shows the principle or outline of the sound sleep living environment support system 1 according to this embodiment. Since this principle or outline is only an example, the usage of each data such as living environment data 4, sleep state 2 data, and subjective data 6 is not limited to the following description, and may be arbitrarily used. It is possible to use it.

A) First, the advice providing unit 9 extracts the user's sleep pattern from the important sleep data (data of the sleep state 2) obtained by the sleep measuring unit 3 (the part for acquiring individual sleep data). Specifically, sleep patterns are derived using sleep indicators such as sleep regularity, sleep efficiency (midway awakening), and sleep onset latency, which are currently important data for sleep satisfaction.

B) Next, the advice providing unit 9 makes a tentative decision on the solution (answer) together with the living environment data 4 from the living environment measurement unit 5 (the part for acquiring the living environment data 4), and is primary. Provide a solution. Specifically, the sleep pattern derived in A) and the living environment data 4 from the living environment measurement unit 5 are combined to provide primary advice 8 (first) on the living environment and life suitable for a good night's sleep. Suggest advice 8a).

For example, the first advice 8a when the living environment is not full of optimum values is
-When the night illuminance of the lighting device is 50 Lx or more and the sleep onset latency is long, the night illuminance of the lighting device is set to 50 Lx.
again,
-If the night set temperature of the air conditioner is 19 ° C and the sleep onset latency is long, the night set temperature of the air conditioner is set to the recommended 21 ° C.

C) Finally, the effectiveness data for the primary solution is acquired as the subjective data 6 using the subjective data acquisition unit 7, and the optimum solution (optimal solution: second solution) is obtained based on the subjective data 6. Try to guide advice 8d). Specifically, a dialogue (including voice dialogue) with the user is performed to confirm the validity of the proposal content. For example, while asking the user about the feeling of sleep satisfaction and making it subjective data 6, if the feeling of sleep satisfaction is low, a dialogue is conducted to find the cause (based on a predetermined scenario), and through the dialogue. , We will learn to connect to the optimal solution.

For example, the second advice 8d, which reflects the user's intention when the living environment is in place, is
-If the living environment is not working and the sleep onset latency is long, for example, it is recommended to take a half-body bath at 38 ° C for 20 minutes.
again,
-When it is hot, for example, it is recommended to lower the set temperature of the air conditioner at night from the recommended 21 ° C to 19 ° C.
-It is also possible to provide other solutions together.

Even for the optimum solution (second advice 8d), the subjective data acquisition unit 7 will continue to confirm whether or not there is any change in the solution through dialogue.

FIG. 3 is a flowchart showing the operation of the comfortable sleep living environment support system 1.

In this flowchart, when the operation starts at the start,
In S1, the advice providing unit 9 reads the data of the sleep state 2 and the living environment data 4 from the sleep measuring unit 3 and the living environment measuring unit 5.

Next, in S2, the advice providing unit 9 obtains a sleep pattern using the sleep state 2 data and the living environment data 4.
Sleep patterns are, for example,
1, 2, 3, 4 Regular (1. Good sleep, 2. Light sleep, 3. Difficult to fall asleep, 4. Difficult to fall asleep lightly)
It is classified into 5, 6, 7, and 8 irregularities (5. Irregular, 6. Irregular awakening, 7. Irregular sleep is difficult to fall asleep, 8. Irregular sleep is light and difficult to fall asleep), and points are given to each. Be done.

Next, in S3, the advice providing unit 9 determines the quality of sleep according to the sleep pattern.

When it is judged that the quality of sleep is good in S3 (1. In the case of a good sleep), in S4, for example, advice 8 "Let's do our best today" is given. Then, in S5, the thermal environment is set to "no setting change".

If it is determined in S3 that there is a problem with sleep quality (1. In cases other than good sleep), factor estimation is performed by scenario conversation on the premise of living environment data 4 in S6. The conversation takes place, for example, when waking up in the morning or returning home at night.

Morning conversations are about sleep, living environment data 4, stress, and so on. These are reflected in air conditioning, lighting settings, etc. In the morning conversation, the living environment data 4 during sleep is also used. These are reflected in air conditioning, lighting settings, etc.

Conversations on the way home at night are, for example, about stress. This is reflected in lighting, bathing, music, aromas, etc.

If the temperature is a factor in S7, the temperature setting is changed in S8 (the next day, in real time), and the feedback is given to S6.

If humidity is a factor in S9, the humidity setting is changed in S10 (next day, in real time) and fed back to S6.

When the light environment is a factor in S11, the illuminance and color temperature of the lighting device are set in S12 and fed back to S6.

If stress is a factor in S13, provide information and services such as recommended bathing, music, and relaxing lighting in S14, and if necessary, further in S15 for external cooperation services. It encourages usage and is fed back to S6.

The operation of this flowchart is performed every day, the results are accumulated in the storage unit 12, learning and the like are performed based on these results, and the results are utilized for sleep of the day and sleep of the next day and thereafter.

Specifically, FIG. 4 shows an example of control when the factor of poor sleep quality (difficulty sleeping) is temperature. (A) is a graph showing the change in temperature (living environment data 4) with the passage of time in the bedroom in summer, and (b) is the body movement (data of sleep state 2) with the passage of time. ) Is a graph. The sleep onset time is, for example, 23:00.

In the summer, for example, when the room temperature in the bedroom exceeds 28 ° C., it feels difficult to sleep, so it is necessary to turn on the air conditioner. As shown in FIG. 4A, the room temperature may exceed 28 ° C. from the beginning (solid line a) or 28 ° C. from the middle (solid line b), but (broken line c). It is desirable for comfortable sleep to control the air conditioner so that the room temperature does not exceed 28 ° C.

For example, when the room temperature (temperature) exceeds 28 ° C from the middle (solid line b), as shown in FIG. 4 (b), body movements during sleep onset and small body movements such as turning over during sleep may occur. After that, the body movement will increase when the room temperature exceeds 28 ° C. for a while at time T.

Therefore, the advice providing unit 9 compares the increase in body movement with the change in room temperature exceeding 28 ° C., determines that the patient is having difficulty sleeping due to environmental factors, and such an increase in body movement occurs. The air conditioner is automatically turned on so that it does not occur (immediately after detecting an increase in body movement, and for sleep the next day). As a result, the room temperature becomes 28 ° C. or lower (as shown by the broken line c), the temperature is finely controlled according to the user's condition, and the body movement is reduced (a good sleep state is maintained). ).

FIG. 5 shows an example of control when the factor of poor sleep quality (difficulty sleeping) is humidity. (A) is a graph showing the change of humidity (living environment data 4) with the passage of time in the bedroom in summer, and (b) is the body movement (data of sleep state 2) with the passage of time. ) Is a graph. The room temperature is constant at 28 ° C.

For example, when the humidity is 80% or more, it is difficult to sleep, so it is necessary to turn on the air conditioner. In FIG. 5A, the humidity exceeds 80% from the middle (solid line). Therefore, it is desirable for comfortable sleep to control the air conditioner so that the humidity does not exceed 80% (as shown by the dashed line).

As shown in FIG. 5B, after the body movement during sleep onset, the body movement increases intermittently when the humidity exceeds 80% for a while. Therefore, the advice providing unit 9 compares the increase in body movement with the change in humidity exceeding 80%, determines that the patient is having difficulty sleeping due to environmental factors, and such an increase in body movement occurs. The air conditioner is automatically turned on (dehumidifying mode) so that it does not occur (immediately after detecting an increase in body movement, and for sleep the next day). As a result, the humidity becomes less than 80% (as shown by the broken line), the humidity is finely controlled according to the user's condition, and the body movement is reduced (a good sleep state is maintained). ).

The temperature and humidity values, which are the threshold values for the above control, can be changed according to the season.

For example, FIG. 6 shows an example of control when the factor of poor sleep quality (coldness) in winter is temperature. (A) is a graph showing a change in temperature (living environment data 4) with the passage of time in a winter living room, and (b) and (c) are body movements (sleep state) with the passage of time. It is a graph which shows (data of 2), (b) is the case where control is not performed, (c) is the case where control is performed.

In winter, for example, if the floor temperature is lower than 19 ° C., it gets cold (coldness makes it difficult to fall asleep), so it is necessary to turn on the air conditioner and the floor heating device. Then, for example, controlling the floor temperature to be 23 ° C. or higher (as shown by the broken line) is desirable for comfortable sleep.

For example, when the floor temperature (temperature) is lower than 19 ° C. (as shown by the solid line), as shown in FIG. 6 (b), the body is cold and the body temperature does not dissipate, so that body movement is often seen. I can't sleep quickly.

On the other hand, when the advice providing unit 9 detects an increase in body movement when falling asleep, for example, it compares the increase in body movement with the floor temperature lower than 19 ° C. The air conditioner and floor heater are automatically turned on on the spot, and the next day, the air conditioner and floor heater are automatically turned on from a time earlier than bedtime (broken line). (Like) Keep the floor temperature (temperature) in the living room at 23 ° C or higher. As a result, as shown in FIG. 6 (c), the body movement at the time of falling asleep is reduced, and it becomes possible to fall asleep quickly. Therefore, the temperature is finely controlled according to the user's condition.

FIG. 7 shows an example of control when the factor of poor sleep quality (coldness) in winter is humidity. (A) is a graph showing the change of humidity (living environment data 4) with the passage of time in the bedroom in winter, and (b) is the body movement (data of sleep state 2) with the passage of time. ) Is a graph. The room temperature is constant at 17 ° C.

For example, when the humidity is 30% or less (as shown by the solid line), it becomes difficult to sleep due to thirst or pain, so it is necessary to turn on the air conditioner to perform the humidification operation. And controlling the air conditioner so that the humidity exceeds 30% (as shown by the dashed line) is desirable for a comfortable sleep. As a result, it is possible to reduce the difficulty of sleeping due to thirst and pain.

For example, when the humidity is 30% or less, as shown in FIG. 7B, due to the difficulty of sleeping due to thirst or pain, the body movement increases after falling asleep, and it becomes impossible to sleep promptly.

On the other hand, when the advice providing unit 9 detects an increase in body movement after falling asleep, it determines that the person feels sleepless due to environmental factors by comparing the increase in body movement with the humidity of less than 30%. Then, on the spot and the next day, the air conditioner is automatically turned on (dehumidifying mode). As a result, as in the case of FIG. 6C, the body movement after falling asleep is reduced, and it becomes possible to fall asleep quickly. Therefore, the humidity is finely controlled according to the user's condition.

FIG. 8 shows an example of control when the cause of poor sleep quality is a light environment. (A) is a graph showing a change in illuminance (living environment data 4) with the passage of time in the living room, and (b) and (c) are body movements (sleep state 2) with the passage of time. It is a graph showing data), (b) is a case where control is not performed, and (c) is a case where control is performed.

In FIG. 8A, it is assumed that the illuminance of the living room is 300 Lx (as shown by the solid line). If the illuminance before going to bed is higher than 50Lx, it will be too bright to fall asleep, so reduce the illuminance in the living room to 50Lx a certain time before going to bed (as shown by the broken line), and turn off the lighting device in the living room at bedtime. Is desirable for a comfortable sleep. For example, when the illuminance (light environment) of the living room is 300 Lx all the time, as shown in FIG. 8 (b), it is difficult to sleep because it is too bright.

On the other hand, when the advice providing unit 9 detects a lot of body movements when falling asleep, it compares the amount of body movements with the illuminance of 300 Lx in the living room and determines that there is a factor of poor sleep in the environment. Then, the next day, control the living room lighting device from an earlier time than bedtime, reduce the living room illuminance to 50Lx a certain time before bedtime (as shown by the broken line), and turn off the living room lighting device at bedtime. .. As a result, as shown in FIG. 8C, the body movement at the time of falling asleep is reduced, and it becomes possible to fall asleep quickly. Therefore, the light environment is finely controlled according to the user's condition.

Further, FIG. 9 shows an example of control when the factor of poor sleep quality is the light environment of the bedroom. (A) is a graph showing a change in illuminance (living environment data 4) with the passage of time in the bedroom, and (b) is a body movement (data of sleep state 2) with the passage of time. It is a graph which shows.

FIG. 9A shows a case where the illuminance of the lighting device in the bedroom is 100 Lx and the person falls asleep with the lighting device on. If the lighting device is left on, as shown in FIG. 9B, the room is bright, and the body movement increases on the way, and it is likely to wake up.

On the other hand, when the advice providing unit 9 detects a large amount of body movement during sleep, it may wake up in the middle due to environmental factors by comparing the amount of body movement with the illuminance of 100 Lx in the living room. It determines that it is there and automatically turns off the lighting in the bedroom (as shown by the dashed line) on the spot. As a result, as in the case of FIG. 8C, the body movement during sleep onset is reduced, and the awakening on the way can be prevented. Therefore, the humidity is finely controlled according to the user's condition.

In addition to the above, when the advice providing unit 9 determines that the cause of the poor sleep quality is the sleep rhythm deviation, the advice providing unit 9 provides the sleep rhythm deviation together with the advice 8c for correcting the sleep rhythm deviation. As the thermal light control for correction, in addition to the above-mentioned control of temperature, humidity and illuminance, for example, at least one of those shown in FIGS. 10A and 10B can be performed.

For example, in FIG. 10A, the floor temperature (floor surface temperature or floor temperature) of the living room is automatically set from a certain time before going to bed (for example, 23:00) (for example, about 2 hours before, for example, around 21:00). It is set to be higher than the target. Further, for example, in FIG. 10B, the living room lighting is started from a short wavelength (blue-white) state from a certain time before going to bed (for example, 23:00) (for example, about 2 hours before, for example, around 21:00). , It is automatically set to low illuminance and long wavelength light (red). All of these are effective in correcting the deviation of the sleep rhythm as a mode (good sleep mode) for obtaining deep non-rem sleep in the early stage of falling asleep.

Further, when the advice providing unit 9 determines that there is a deviation in sleep regularity, the temperature, humidity, and illuminance are combined with the advice 8e for correcting the deviation in sleep regularity, as in the case of the deviation in sleep rhythm. And the thermal light control shown in FIGS. 10 (a) and 10 (b) can be performed. The sleep regularity deviation includes, for example, a weekday-holiday deviation (FIG. 11) and a continuous weekday deviation (FIG. 12).

The deviation between weekdays and holidays may be defined in any way. For example, in the case of FIG. 11, the sleep time in the past week is measured, the average sleep time (weekday average) is calculated, and the holiday If there is a deviation of ± 2 hours or more compared to the average sleep time (Friday average) of (Friday), or a deviation of 20% or more with respect to the sleep time, it is judged that there is a deviation of sleep regularity. I try to do it.

In this case, at a fixed time such as a certain time (for example, about 2 hours) before the average bedtime with respect to sleep on holidays so that the Friday-Saturday average is corrected toward the weekday average. , It is preferable that at least one of the thermal light controls shown in FIGS. 10 (a) and 10 (b) is continuously performed.

Further, the continuous deviation on weekdays may be defined in any way. For example, in the case of FIG. 12, the sleep time in the past week is measured and the average sleep time (weekday average) is obtained. If there is a deviation of ± 2 hours or more with respect to the average sleep time, or a deviation of 20% or more with respect to the sleep time for about 2 to 3 days or more in a week, there is a deviation of sleep regularity. I try to judge.

In this case, for all weekday sleep, for example, a certain amount of time (for example, about 2 hours) before the average bedtime so that all weekday sleep is corrected toward the weekday average. It is preferable to continuously perform at least one of the thermal light controls shown in FIGS. 10 (a) and 10 (b) at a fixed time.

By continuously performing these thermal light controls for a long period of time, it can be expected that the deviation of sleep regularity will be improved.

It should be noted that it is not always necessary to calculate the weekday average for such a shift in sleep regularity in units of one week, and for example, it is easy to get up and go to bed within the range of 3 days to 1 month. It is preferable to be able to set the period as described above. By making the period setting variable in this way, for example, as shown in FIG. 13, the sleep time changes with the seasons according to the sunshine hours (the shorter the sunshine hours, the longer the sleep time tends to be). It is also possible to support changes in sleep time according to the sunshine hours that change with the seasons.

<Effect> Hereinafter, the action and effect of this example will be described.
