Description

The present invention relates to a sleep support device.

A short nap may be taken to relieve fatigue and drowsiness. From this, in Patent Document 1, the awakening condition is determined based on the purpose of nap such as drowsiness reduction, recovery from fatigue and improvement of work performance, and when the awakening condition is satisfied while maintaining the sleep stage at a predetermined sleep stage. , Proposes a sleep control device that stimulates and awakens.

By the way, a nap different from normal sleep includes a so-called nap. It is known that a nap is generally performed during the daytime during normal sleep, and that the activation of brain cells (suppression of aging of brain cells) can be achieved by taking a nap for an appropriate time.

Japanese Unexamined Patent Publication No. 2010-082377

However, taking a nap longer than necessary can be counterproductive. In addition, there are deep sleep and light sleep in sleep, and when awakening from deep sleep, a feeling of lack of sleep occurs.

The present invention has been made in view of the above facts, and an object of the present invention is to provide a sleep support device capable of obtaining a comfortable nap.

The first aspect for achieving the above object is to perform a sleep detection means for detecting the sleep state of the user who has entered the bed, a sleep environment adjusting means for adjusting the sleep environment of the user who has entered the bed, and a nap. When controlling the sleep environment adjusting means for the user based on the sleep state detected by the sleep detecting means, falling asleep is promoted during the awakening period in which the awakening of the user who has entered the bed is detected. During the sleep period in which sleep onset is detected, the sleep state is controlled so as to be a sleep environment in which the sleep state is suppressed from becoming deeper than a predetermined sleep state, and the person enters the bed. It includes a control means for controlling the sleep environment so that sleep is disturbed when a person wakes up after a preset time has elapsed.

According to the first aspect, the sleep environment adjusting means is controlled when the user takes a nap, and a sleeping environment in which the user can easily fall asleep can be obtained during the awakening period when the user who has entered the bed does not fall asleep. By doing so, the user is encouraged to fall asleep. In addition, during the sleep period in which the user is sleeping, the sleeping environment is adjusted so that the sleeping state of the user does not become deeper than a predetermined sleeping state (for example, a light sleeping state).

After that, when the user wakes up after a predetermined time (for example, about 30 minutes) has elapsed, the sleep environment adjusting means is controlled so as to provide a sleep environment that interferes with the sleep of the user. As a result, it is possible to suppress sleeping for a predetermined time or longer and obtain a comfortable feeling of sleep.

In the second aspect, as the sleeping environment adjusting means, a radiant temperature adjusting means for releasing cold heat at the time of cooling as radiant heat and releasing hot heat at the time of heating to control the temperature is provided, and the control means is said to be awakened at the time of cooling. During the period and the sleep period, radiant heat is emitted so as to be lower than the predetermined cooling set temperature, and when the person wakes up, radiant heat is emitted so as to be higher than the cooling set temperature. By controlling the radiant temperature adjusting means, radiant heat is emitted so as to reach a predetermined heating set temperature during the awakening period and the sleeping period during heating, and from the heating set temperature when waking up. The radiant temperature adjusting means is controlled so as to emit radiant heat so as to have a high temperature.

According to the second aspect, radiant heat is emitted so as to be lower than the predetermined cooling set temperature during the awakening period and the sleeping period during cooling, and the temperature is higher than the cooling set temperature when waking up. Radiant heat is emitted so as to become. Further, during heating, during the awakening period and during the sleeping period, radiant heat is emitted so as to reach a predetermined heating set temperature, and when waking up, radiant heat is emitted so as to be higher than the heating set temperature.

In general, regarding the temperature in the sleeping environment, it is easier to fall asleep by setting the temperature environment slightly lower than the temperature at which the person feels comfortable (heating set temperature or cooling set temperature), and the temperature is higher than the temperature at which he / she feels comfortable. Sleeping is hindered by the high temperature environment. Therefore, in the second aspect, the user's sleep is promoted during the awakening period, the deepening of the user's sleep during the sleep period is suppressed, and the user's sleep is hindered when waking up.

In the third aspect, the lighting means is provided as the sleep environment adjusting means, and the control means is made darker than the predetermined brightness during the awakening period, and the predetermined brightness is obtained when the person wakes up. The lighting means is controlled so as to be brighter than that.

According to the third aspect, the user is encouraged to fall asleep by controlling the lighting means so as to darken during the awakening period. Further, when waking up, the user can be awakened by controlling the lighting means so as to brighten the lighting.

A fourth aspect includes the control means controlling the lighting means so that the light source color of the lighting is a light bulb color during the awakening period and white when the person wakes up.

According to the fourth aspect, the color of the illumination (light source color) is controlled so that the color becomes light bulb color during the awakening period and becomes white when waking up. The light bulb color is a calm color and can encourage the user to fall asleep. In addition, white is a color that can suppress the sleep of the user, and can promote the awakening of the user.

A fifth aspect comprises a light-shielding means for switching between daylighting and light-shielding as the sleep environment adjusting means, and the control means controls the light-shielding means so as to block light during the awakening period and to collect light when the person wakes up. ..

According to the fifth aspect, the user can easily wake up by switching from the shaded state to the daylighted state. In addition, when waking up, the user is encouraged to awaken by setting the lighting state.

As described above, according to the present invention, since the sleeping environment is controlled so that sleep during nap is not promoted, so-called oversleeping can be suppressed. Further, according to the present invention, since sleep is not promoted when taking a nap, it is possible to wake up from a light sleep state, and it is possible to obtain an effect that the feeling of lack of sleep is suppressed.

Further, the controller 50 controls the lighting and the temperature control described later based on the wake-up time set by the timer 48.

In the building where the bedroom 10 is provided, an air conditioner in the entire building (hereinafter referred to as an air conditioner 64; see FIG. 2) is installed as an example of the air conditioner. The air conditioner 64 generates air conditioning air at a preset temperature and blows air conditioning air from outlets provided in each of the living room, corridor, bathroom, etc. of the building to predetermine the entire interior of the building. It operates to adjust the temperature to the same temperature and maintain the temperature control state. As shown in FIG. 1, in the bedroom 10, the outlet 66 of the air conditioner 64 is provided on the wall 14. The bedroom 10 is temperature-controlled by the temperature-controlled air-conditioning air blown from the outlet 66.

As shown in FIG. 2, an air conditioner 64 is connected to the controller 50. The controller 50 controls the air volume of the conditioned air blown out from the outlet 66 in three stages, for example, strong, medium, and weak. As shown in FIG. 1, the bedroom 10 is provided with, for example, a ventilation port 68 on the floor 22 so that the bedroom 10 can be ventilated.

On the other hand, the bedroom 10 is provided with a radiant device 70 as a radiant temperature controlling means different from the air conditioner 64. The radiating device 70 is provided with a radiating device 70L corresponding to the bed 42L and a radiating device 70R corresponding to the bed 42R.

As an example, the radiant devices 70L and 70R are provided with three radiant panels 72, the radiant device 70L has three radiant panels 72 arranged on the wall 18, and the radiant device 70R has three radiant panels 72 on the wall 20. 72 are arranged. Each of the radiant panels 72 is provided with a refrigerant circulation path inside, and the refrigerant whose temperature is controlled by the apparatus main body (not shown) flows through the circulation path, so that the radiant heat (hot or cold) generated from the refrigerant is grilled 74. It is released from the entire surface of. The radiation devices 70L and 70R have the same basic configuration, and when the radiation devices 70L and 70R are not distinguished, they will be described as the radiation device 70.

In the radiant device 70, the radiant heat emitted from the grill 74 of the radiant panel 72 hits the person or bedding, so that the person or bedding is directly temperature-controlled (cooled or heated). In the bedroom 10, the temperature of the user of the bed 42 can be individually controlled by the radiation device 70.

Further, the radiant device 70 has a radiant panel 72 so as to have a preset temperature (hereinafter, heating set temperature or cooling set temperature) at a preset target position such as a position on the bedding of the bed 42 or a position of the user. Operates to emit radiant heat from. For example, when a user who has entered the bed 42 is targeted for temperature control, the radiant device 70 radiates heat from the radiant panel 72 so that the user's sensible temperature becomes a set temperature (cooling set temperature or heating set temperature). Is released. At this time, the radiant device 70 lowers the temperature of the refrigerant below the set cooling temperature so that the user's sensible temperature becomes the set cooling temperature during cooling, and emits radiant heat (cold heat) at a temperature lower than the set cooling temperature. Therefore, the user is made to receive the radiant heat of the cooling set temperature. Further, at the time of heating, the radiant device 70 raises the temperature of the refrigerant higher than the set heating temperature so that the user's sensible temperature becomes the set heating temperature, and emits radiant heat (heat) having a temperature higher than the set heating temperature. , The user is made to receive the radiant heat of the heating set temperature.

In the radiation device 70, the temperature at which the user feels comfortable during cooling (sensible temperature) is set to the cooling set temperature, and the temperature at which the user feels comfortable during heating is set at the heating set temperature. Further, in the radiation device 70, for example, the temperature at the target position (the sensible temperature of the user) is higher than the set temperature, the sensible temperature of the user is the set temperature, and the sensible temperature of the user is higher than the set temperature. It is possible to switch to three levels of low and low. The radiant device 70 may have the set temperatures and intensities of the three radiant panels 72 individually set, but in the present embodiment, for the sake of simplification of the description, the three radiant devices 70 may be set individually. It is assumed that each of the radiation panels 72 operates at the same set temperature and intensity.

As shown in FIG. 2, the radiating device 70 is connected to the controller 50. The controller 50 controls the radiating device 70 so that the user who is in the bed 42 can obtain a predetermined temperature control state. At this time, the controller 50 controls the operation of the radiation device 70 (radiation panel 72) in three stages of high, medium, and weak according to the sleep state of the user detected by the sleep sensor 52. In the radiant device 70, the cooling set temperature and the heating set temperature may be set on, for example, an operation panel (not shown) connected to the controller 50, and the radiant device 70 is not shown. It may be set on the operation panel.

Further, as shown in FIG. 1, the bedroom 10 is provided with, for example, an aromatherapy device (hereinafter referred to as an aroma device 78) on each of the bed 42L side and the bed 42R side. The odor includes an odor that promotes sleep and an odor that suppresses arousal, and the aroma device 78 emits an odor that promotes sleep of the user (fragrance) or an odor that promotes awakening of the user (fragrance). ..

As shown in FIG. 2, the aroma device 78 is connected to the controller 50. The controller 50 controls the operation of the aroma device 78 so that, for example, an odor that promotes sleep is emitted upon the user entering the floor. In addition, the controller 50 controls the aroma device 78 so that the odor that promotes arousal is emitted at the timing of waking up of the sleeping user.

By the way, in general, deep sleep and light sleep are periodically repeated in sleep, whereby a comfortable sleep can be obtained. In addition, awakening from sleep is better when awakening from a light sleep state than when awakening from a deep sleep state, and when awakening from a deep sleep state, a feeling of lack of sleep occurs. Further, the light source of the illumination has a color temperature of the light source, and the color of the illumination (the atmosphere in the illuminated bedroom 10) differs depending on the color temperature. The color temperature of the illumination includes yellow, which is a light bulb color, and white, which is a fluorescent lamp color having a color temperature higher than that of the light bulb color (daylight white or daylight color having a temperature higher than that of neutral white). In a sleeping environment, white, which has a higher color temperature than yellow (bulb color), interferes with sleep, but yellow (bulb color), which has a lower temperature, provides calmness and interferes with sleep. Less (sleeps well). Further, the lighting has a sleep-onset effect in a dark atmosphere (for example, a dim atmosphere), but in a bright atmosphere, the increase in brightness hinders sleep, and it is preferable that the lighting is bright when waking up.

In addition, the air-conditioning at bedtime is lower than the temperature at which it feels comfortable, and it is better to feel cool, and the temperature is higher than the temperature at which it feels comfortable, which hinders sleep. In addition, the heating at bedtime sleeps better when the temperature is lower than the temperature at which the person feels comfortable, and the temperature becomes higher than the temperature at which the person feels comfortable, which hinders sleep.

From here, the controller 50 performs lighting control including the brightness of the lighting and the color temperature of the light source according to the sleep state of the user detected by the sleep sensor 52 and the wake-up time set by the timer 48. In addition, the controller 50 operates the aroma device 78 when the user enters the floor or the user wakes up. As a result, the sleep support device 12 makes it possible to obtain an environment in which sleep is promoted or an environment in which waking up is promoted as a sleep environment for the user.

Further, the sleep state is periodically repeated between a light sleep state and a deep sleep state. The controller 50 controls the radiation device 70 (radiation panel 72) according to the sleep state detected by the sleep sensor 52, that is, whether the sleep is light or deep or awake. As a result, the sleep support device 12 promotes the change of the sleep state at a predetermined cycle, so that the user can obtain a comfortable sleep state. At this time, since the bedroom 10 is air-conditioned by the air-conditioning device 64 that air-conditions the entire building, the controller 50 does not directly control the air-conditioning device 64, but mainly uses the radiant device 70 to control the individual temperature. Do.

On the other hand, the controller 50 is provided with an information collecting unit 80 and a sleep determining unit 82. The controller 50 functions as the information collection unit 80 and the sleep determination unit 82, for example, when the CPU executes the information collection program and the sleep determination program.

The information collecting unit 80 collects various information related to sleep such as the time when the user enters the bed 42, various information regarding the physical condition of the user, and the sleep history of the user. The time when the user enters the floor is acquired from, for example, the timer 48. For example, when the user wears a wearable terminal before entering the bed (while waking up), the information regarding the physical condition of the user includes the amount of activity, blood pressure, heart rate, and the amount of activity detected by the wearable terminal. Information on physical condition such as body temperature is applied, and the information collecting unit 80 acquires this information from the wearable end pressure. As for the amount of activity of the user, for example, the amount of exercise of the user detected by a pedometer (registered trademark) or the like may be acquired. In addition, as the information regarding the physical condition of the user, blood pressure, heart rate, body temperature, etc. may be detected from the user who has entered the bed, and the detected information may be included.

As information on the sleep of the user, when the daily entry time, wake-up time, sleep time, etc. of the user are stored as the sleep history, the stored sleep history is read and acquired. In addition, the information regarding the sleep of the user may include the elapsed time from the wake-up time. Further, the information acquired by the information collecting unit 80 includes the wake-up time set by the user in the timer 48.

The sleep determination unit 82 determines whether or not the purpose of entering the bed of the user is a so-called nap as a nap, based on the information acquired by the information collection unit 80. In the present embodiment, the nap mainly refers to a nap (hereinafter, the nap will be described as a nap). For example, the sleep determination unit 82 determines in advance the elapsed time from waking up when the time of entering the bed is different from the time of normal sleep (for example, the time between 11:00 am and 3:00 pm). If you have more than 3 hours of sleep, if you have enough sleep, if you do not have enough exercise and do not need sleep to recover from fatigue (recovery of physical condition), or if you do not need to rest for colds, etc. It is determined that the purpose of entering the bed of the user is to take a nap in such a case. Further, when the wake-up time set by the timer 48 is within 30 minutes, the sleep determination unit 82 determines that the purpose of entering the user is to take a nap. That is, the sleep determination unit 82 can determine that the purpose of sleep is a nap when it is assumed that the user is set to take a nap.

Next, the sleep environment control by the sleep support device 12 will be described as the operation of the present embodiment with reference to FIGS. 3 to 5. In the following description, it is assumed that the user who goes to bed is determined for each bed 42.

The controller 50 sets and stores a nap control pattern (nap control pattern) applied to the nap in addition to the normal control pattern applied to the normal sleep other than the nap as the control pattern of the sleep environment. FIG. 3 shows an example of the nap control pattern according to the present embodiment. Further, in FIGS. 5 (A) to 5 (C), in the nap control pattern, the lighting device 54, the shading device 60, the radiation device 70, and the aroma device 78 according to the sleep state of the user and the change in the sleep state. The timing chart of the operation of is shown.

As shown in FIGS. 5 (A) to 5 (C), the sleep state of the user who entered the bed includes the awakening period Ta in which the user does not fall asleep and the sleep period in which the user falls asleep (sleeps). It is roughly divided into Tb. As shown in FIGS. 3 and 5 (A) to 5 (C), the nap control pattern executed by the controller 50 is set so as to promote the user's sleep onset during the awakening period Ta, and during the sleep period Tb. It is set so that the user's sleep does not become deep, and further, it is set to awaken within a preset time (for example, 30 minutes) after entering the bed.

FIG. 4 shows an example of sleep support control by the controller 50. This flowchart is executed, for example, when the sleep sensor 52 detects that the user has entered the bed 42, and in the first step 100, information on the sleep of the user who has entered the bed 42 is collected. Further, in the next step 102, the sleep purpose of the user who has entered the bed 42 is determined, and in step 104, it is determined whether or not the determined sleep purpose is a nap.

Here, as the information on the sleep of the user, various information on sleep such as the time when the user entered the bed 42, various information on the physical condition of the user, and the sleep history of the user can be applied. In the present embodiment, as an example, at least information that can determine whether or not the user's sleep purpose is a nap is applied.

For example, from the information on the sleep history of the user, when the user enters the bed during the normal sleep time zone, it is determined that the purpose of sleep is normal. In addition, if the elapsed time from the previous wake-up is shorter than the preset time (for example, 3 hours), there is a possibility of so-called double sleep, and if the previous sleep time is short or for the last few days. If the average sleep time is short, there is a possibility of so-called stagnation. In these cases, it is classified as a normal sleep purpose rather than a nap. Furthermore, based on physical condition information such as the amount of activity of the user, when the amount of exercise of the user before entering the bed is large, or when the user's heart rate, blood pressure, body temperature, etc. are higher than usual (for example, a cold). If it is judged that you are in poor physical condition), there is a possibility of sleeping for recovery of physical strength or physical condition, and in this case as well, it is classified as a normal sleep purpose instead of taking a nap.

On the other hand, if the bedtime is different from the normal sleep time zone, for example, from 11:00 am to 3:00 pm, and the elapsed time after waking up is, for example, 3 hours or more, a nap is taken. Is determined to be the purpose. Further, when the wake-up time is set in the timer 48 and the time until the wake-up time (sleep purpose time) is set within 30 minutes, for example, when the user inputs information for the purpose of taking a nap. , It is judged that the purpose is to take a nap.

Here, if it is determined in step 102 that the purpose of entering the bed of the user is not a nap but a purpose classified into normal sleep, a negative determination is made in step 104 and the process proceeds to step 106. In this step 106, control based on a preset normal control pattern is executed.

In the normal control pattern, for example, the lighting device 54 is controlled so as to be a lighting state in which the user's sleep is promoted from the sleep state of the user detected by the sleep sensor 52 until the user falls asleep. The radiation device 70 is controlled so that the temperature control temperature is lower than the set temperature (heating set temperature or cooling set temperature) that the user feels comfortable with. As a lighting state that promotes the user to fall asleep, for example, a brightness of about 9 lx (dim brightness), which is the brightness of a candle with a yellow light bulb color, is applied.

Further, the controller 50 controls the light-shielding device 60 so that the inside of the bedroom 10 is in a light-shielding state, and controls the aroma device 78 so that an odor that promotes the user's sleep (sleeping) is emitted. As a result, the sleep support device 12 can promote the user to fall asleep.

In the normal control pattern, when the user falls asleep, the controller 50 turns off the lighting device 54 and turns it off, and the radiating device promotes the periodic repetition of the deep and light sleep states of the user. Control 70. Further, the controller 50 stops the operation of the aroma device 60 when the user falls asleep. Further, when the wake-up time is approached (for example, 15 minutes before the wake-up time is reached), the controller 50 controls the lighting device 54 so as to brighten the illumination (for example, a brightness of about 100 lx in white) and warms the temperature. The radiation device 70 is controlled so that the temperature control temperature is higher than the cooling set temperature or the heating set temperature.

After that, when the wake-up time is reached, the controller 50 controls the lighting device 54 so as to make the lighting even brighter (for example, about 1000 lx). Further, the controller 50 operates the light-shielding device 60 to bring it into a daylighting state, controls the aroma device 78 so as to emit an odor that encourages the user to awaken, and sounds an alarm (alarm sound) of the timer 48 at the wake-up time. By ringing, it notifies that the wake-up time has been reached.

Further, when the user's wake-up is detected, a positive determination is made in step 108, and sleep control is terminated. As a result, the user can obtain a comfortable sleeping state during sleep, and when waking up, the user is awakened from a light sleep state and a comfortable awake state can be obtained.

On the other hand, when it is determined that the purpose of sleep is a nap, an affirmative determination is made in step 104, and the process proceeds to step 110. In this step 110, the nap control pattern is executed, and when the user wakes up, a positive determination is made in step 112, and the execution of the nap control pattern ends.

As shown in FIGS. 3 and 5 (A) to 5 (C), in the nap control pattern executed by the controller 50, the radiation device 70 is set to be comfortable for the user before the user enters the floor. Operated at temperature, the shading device 60 is operated to bring the window 36 into a daylighting state. Further, the lighting device 54 is controlled so that the light source color is yellow, which is the color of a light bulb, and the brightness is about 500 lx, and the aroma device 78 is stopped.

Here, when the sleep sensor 52 detects the user entering the floor and starts the control based on the nap control pattern, the radiant device 70 operates at "medium", which is the set temperature during cooling. During heating, it is controlled to operate at "low", which is lower than the set temperature. Further, the light-shielding device 60 is controlled so that the window 36 is in a light-shielding state, and the lighting device 54 has a brightness of, for example, about 9 lx (about the brightness of a candle) and a light source so as to promote falling asleep of the user. The color is controlled to be yellow (bulb color). As a result, during the awakening period Ta, the user who has entered the bed 42 is promoted to fall asleep. The aroma device 78 may be controlled to emit an odor that promotes the user's sleep, but in order to suppress the odor that promotes the user's sleep from remaining at the time of waking up, the present embodiment Then, the operation of the aroma device 78 at the time of falling asleep is stopped.

When the user falls asleep, the sleep period Tb is entered, and the lighting device 54 is controlled to be turned off. Further, as shown in FIGS. 3 and 5 (A), when the sleep state of the user who has fallen asleep continues to be shallow, the radiant device 70 is set to the set temperature at "medium" during cooling. The operation of is continued, and the operation at "low" lower than the set temperature is continued during heating. Further, the light-shielding device 60 is controlled to continue the light-shielding state, and the lighting device 54 is controlled to continue the light-off state. As a result, the user who has fallen asleep is prevented from deepening the sleep state (the shallow state is maintained).

After that, when a predetermined time elapses and the wake-up time is reached, the controller 50 controls the temperature control and lighting so as to create a sleeping environment that interferes with the sleep of the user. That is, the timer 48 is controlled so as to sound an alarm to notify that the wake-up time has been reached. The radiant device 70 is controlled to operate at a “high” temperature higher than the set temperature during both cooling and cooling, and is switched to a temperature control state that interferes with the sleep of the user. Further, the shading device 60 is operated so as to be in a daylighting state, and the lighting device 54 is controlled to be lit so that the light source color is white and bright (for example, about 1000 lx) so as to interfere with the sleep of the user. To. Further, the aroma device 78 is controlled to emit an odor that promotes the awakening of the user. As a result, the user sleeps for an appropriate sleep time and awakens (wakes up) from a light sleep state at the time of waking up.

On the other hand, as shown in FIGS. 3 and 5B, when the sleep state of the user who has fallen asleep shifts to a deep state, the controller 50 controls the sleep state to be shallow. That is, the controller 50 controls the radiant device 70 so that when the sleep state of the user detected by the sleep sensor 52 becomes deeper, the radiant device 70 operates at a “high” temperature higher than the set temperature during cooling, even during heating. For example, the radiant device 70 is controlled so as to operate in "medium".

Further, the controller 50 controls the shading device 60 so that the light is taken from the window 36, and also controls the lighting device 54 so that the light source color is white and the brightness becomes a predetermined brightness (for example, 1000 lx) at the wake-up time. Gradually brighten to reach. Further, the controller 50 controls the aroma device 78 to emit an odor that promotes arousal. As a result, the sleep support device 12 forms a sleeping environment that interferes with the sleep of the user. As a result, the user shifts from a deep sleep state to a shallow sleep state, and is awakened from the light sleep state at the time of waking up.

In addition, after the user falls asleep, if the control is performed so as to suppress the deepening of the sleep state of the user, the user may awaken before the wake-up time. As shown in FIGS. 3 and 5 (C), the controller 50 controls the lighting device 54 to promote the user's sleep (sleeping) when the user's awakening is detected before the wake-up time. That is, the controller 50 controls the lighting device 54 so that the brightness is, for example, about 9 lx and the light source color is yellow (bulb color), so that the user calms down and promotes falling asleep again.

Further, the controller 50 controls the radiant device 70 so as to operate at "medium" during cooling and at "low" during heating. Further, the controller 50 controls the shading device 60 so that the daylighting state is continued if the daylighting state is present. When the controller 50 is in a light-shielding state, the controller 50 controls the light-shielding device 60 so as to continue the light-shielding state.

On the other hand, if the user does not wake up when the wake-up time is reached, the controller 50 continues the operation of the lighting device 54, the shading device 60, the aroma device 78, and the radiating device 70 so as to interfere with the user's sleep. As a result, the user sleeps for an appropriate sleep time and is awakened from a light sleep state at the time of waking up.

As described above, when the user takes a nap, the sleep support device 12 controls so as to promote the user's sleep after entering the bed (wake period Ta), but after the user falls asleep (sleep period Tb). Controls the user so that he / she does not sleep deeply. That is, when the user's sleep state is light, it is controlled so that the sleep is continued, but when the user's sleep state becomes deep, the lighting device 54, the shading device 60, and the radiation device are controlled so as to interfere with the user's sleep. 70 and the aroma device 78 are controlled.

As a result, the user can wake up from a state of light sleep, so that a good feeling of awakening can be obtained without causing a feeling of lack of sleep. That is, when awakening from a deep sleep state, the user may not be able to obtain a good feeling of awakening due to, for example, a feeling of lack of sleep, but since he / she awakens from a state of light sleep, a good feeling of awakening can be obtained. In addition, since the user is awakened by the passage of a predetermined sleep time, it is possible to prevent the user from having a long nap time.

Therefore, the sleep support device 12 can suppress the user from feeling lack of sleep even if the sleep time is a predetermined time, so that a comfortable nap can be performed.

On the other hand, between noon (for example, around 11 am) and evening (for example, around 3:00 pm), which is the time zone during normal sleep time, a nap gives a more appropriate sleep time (for example, about 30 minutes of sleep). It is known that when time is obtained, brain cells are activated. In addition, it is known that brain disorders such as dementia are suppressed in elderly people, for example, by activating brain cells by taking a nap.

The sleep support device 12 according to the present embodiment suppresses the user from sleeping for a predetermined time or longer when the sleep purpose of the user is determined to be a nap. Therefore, for example, cognition by the elderly and the like. The onset of dementia can be suppressed.
