Description

  The present invention relates to a sleep control method and a sleep control device, and can be applied to a device that adjusts a biological rhythm, for example.

  A person adjusts the biological rhythm by the illuminance of light or the like. The biological rhythm is a rhythm of life such as a time to wake up or a sleep time.

  In modern times, there are many factors that disturb the biological rhythm. For example, when a day is spent indoors where the illuminance of light is kept constant, the rhythm of the living body tends to be disturbed. In view of this, a technique for returning such disturbance of biological rhythm to a normal state has been developed.

  For example, Patent Literature 1 discloses a technique for measuring a biological rhythm of a person in advance and adjusting the biological rhythm by applying an appropriate stimulus to the person based on the result. A technique for measuring illuminance and environmental temperature and adjusting the environmental temperature based on the result is disclosed in Patent Document 2. Patent Document 3 discloses a technique for adjusting a biological rhythm by adjusting the illuminance of light throughout the day.

  In addition, the technique which controls environmental temperature for obtaining a favorable sleep state is disclosed by patent document 4, for example.

  In recent years, it has become possible to move in a short time due to the development of transportation means. For this reason, when moving to a place with a time difference, the biological rhythm is often disturbed due to the time difference blur. It takes time to return the biological rhythm once disturbed to a normal state, and the discomfort due to jet lag is prolonged.

  In order to adjust the biological rhythm, for example, the bedtime and the wake-up time are changed. For this change, light can be used as disclosed in, for example, Patent Document 1 described above. The biological rhythm includes a circadian rhythm that makes a person sleepy and active according to ambient brightness. Therefore, the light can be changed to a circadian rhythm by changing its illuminance or the like, so that the bedtime and the wake-up time can be advanced or delayed.

  However, although the biological rhythm can be adjusted by light, there is a possibility that good sleep cannot be obtained because the biological rhythm has changed. Factors that determine the quality of sleep state include falling asleep, depth of sleep, and awakening. When good sleep cannot be obtained, for example, it is caused by poor sleep and awakening during sleep or awakening is not smooth. If good sleep cannot be obtained, the biological rhythm once adjusted may be disturbed.

First embodiment.
In the present embodiment, the sleep time is advanced and the sleep time is shortened. For example, it is desirable to apply when sleep time needs to be within 4 hours. FIG. 1 is a flowchart showing a sleep control method according to the present embodiment. The sleep control method includes steps 11 to 15.

  In step 11, sleep is promoted in order to advance the sleep time. Examples of methods for promoting sleep falling include the following. In the first method, the body temperature of a person is increased by increasing the environmental temperature, for example, from a time point that is a predetermined period after the scheduled time of sleep to a point of sleep. For example, by raising the body temperature by 0.2 ° C. during a period from 30 minutes to 60 minutes after the scheduled sleep time to the sleep time point, the person feels moderate warmth and wants to sleep.

  The second method provides a person with light having an illuminance and a color temperature having a calming effect from a time point that is a predetermined period after the scheduled time of sleep to a point of sleep. For example, from 60 minutes to 30 minutes before the scheduled sleep time, a person is given light with an illuminance of 500 lux or less and a color temperature of 1000 K or less. Thereafter, from 30 minutes before the scheduled sleep time to the sleep time, the person is given light with an illuminance of 50 lux or less and a color temperature of 1000 K or less. Light with an illuminance of 500 lux or less makes people feel the dimness of the surroundings. Moreover, the light whose illuminance is 50 lux or less makes a person feel the darkness of the surroundings. Light with a color temperature of 1000 K or less is reddish in color, and makes people feel warm through vision.

  One of the first and second methods may be adopted as step 11 or both may be adopted and performed in parallel.

  According to the first and second methods, falling asleep is promoted. That is, the biological rhythm is adjusted by advancing the sleep time.

  In parallel with the first or second method, a scent may be given to a person from a time point that goes back a predetermined period from a scheduled sleep time to a sleep time point. For example, a scent such as lavender, chamomile, or orange is given to a person 30 minutes before the scheduled sleep. This makes people relax.

  In addition, sound transmitted to a person may be blocked from a time point that goes back a predetermined period from a scheduled sleep time to a sleep time point. For example, the noise transmitted to the person trying to fall asleep is cut off 30 minutes before the scheduled sleep. Thereby, a person can fall asleep in a quiet state.

  Or you may make a person listen to music from the time of going back for a predetermined period from the scheduled time of sleep to the time of sleep. For example, people can listen to music containing a lot of α waves and music with a healing effect 30 minutes before the scheduled sleep. This makes people relax.

  By these methods, promotion of falling asleep can be assisted. In other words, by performing in parallel with the first or second method, the promotion of falling asleep becomes more effective.

  In step 12, after falling asleep, the environmental temperature is lowered, for example, monotonously, for a predetermined period. FIG. 2 shows a change in environmental temperature with respect to sleep time by a solid line 122. The solid line 122 includes solid lines 122a, 122b, and 122c. A solid line 122a indicates a change in the environmental temperature after falling asleep due to the control of the environmental temperature in Step 12. A solid line 122b indicates a change in the environmental temperature after the environmental temperature reaches the minimum value due to the environmental temperature control in Step 13 described later. A solid line 122c indicates a change in the environmental temperature before awakening due to the environmental temperature control in step 14 described later.

  The environmental temperature indicated by the solid line 122a is set to 29 ° C. during sleep. Thereafter, about 90 minutes is adopted as the predetermined period, and the environmental temperature is monotonously lowered to about 28 ° C. during this period. As the environmental temperature decreases, the human body temperature also decreases. Such an environmental temperature control method is disclosed in, for example, Patent Document 4.

  Since the body temperature is lowered in Step 12 after Step 11 that promotes falling asleep, it is possible to lead to a good sleep state.

  In step 13, after the environmental temperature reaches the minimum value by the control in step 12, the environmental temperature is held at the minimum value. The change in the environmental temperature controlled in step 13 is indicated by a solid line 122b in FIG. The ambient temperature is held at a minimum value of 28 ° C. for about 30 minutes.

  If it is necessary to further reduce the sleeping time, the process may proceed from step 12 to step 14 described later without going through step 13.

  In step 14, the surrounding environment of the person before awakening is controlled. Step 14 includes a step 141 for increasing the ambient temperature in a predetermined period, for example, a monotonous increase, and a step 142 for promoting awakening, before the scheduled awakening time.

  The change in the environmental temperature controlled in step 141 is indicated by a solid line 122c in FIG. The environmental temperature adopts about 60 minutes as a predetermined period, and is monotonously increased from the minimum value of 28 ° C. to 29 ° C. in this predetermined period. After a predetermined period of time, awakening occurs. In addition, as the environmental temperature increases, the human body temperature also increases. Such an environmental temperature control method is disclosed in, for example, Patent Document 4.

  The contents of step 141 can be grasped when the environmental temperature is increased in the predetermined period from the point in time preceding the predetermined period from the scheduled awakening point.

  In step 142, in order to promote awakening, a person is given light having an illuminance and a color temperature that have excitatory action from a time point that is a predetermined period after the expected time point of awakening to a time point of waking. For example, light having an illuminance of about 1000 lux and a color temperature of about 3000K is given to a person 30 minutes before the scheduled awakening time. Light with an illuminance of about 1000 lux makes people feel the brightness of the surroundings. In addition, light having a color temperature of about 3000K has a bluish color and makes people feel chilly through vision.

  In parallel with step 142, the scent may be given to the person from the time point awakened by a predetermined period from the scheduled time point for awakening to the point of awakening. For example, a scent such as peppermint, caffeine or basil is given to a person 30 minutes before the scheduled awakening. Thereby, a person can obtain a refreshing feeling and can assist promotion of arousal. That is, by performing in parallel with step 142, promotion of awakening is made more effective.

  In step 15, the sleepiness after waking is weakened by giving a person a light having an illuminance and a color temperature having an exciting effect. For example, a person is given light with an illuminance of 2500 lux or more and a color temperature of about 5000K. Light with an illuminance of 2500 lux or more makes people feel the brightness of the surroundings. In addition, light having a color temperature of about 5000K is bluish and makes people feel chilly through vision.

  According to the sleep control method described above, even when the sleep time and awake time are advanced in order to adjust the biological rhythm, the environmental temperature is lowered after promoting sleep, so that a good sleep state can be obtained. Moreover, awakening can be led smoothly. Moreover, even if sleepiness remains after waking up, sleepiness can be weakened.

  Moreover, since the environmental temperature is held at the minimum value after the environmental temperature is monotonously lowered to the lowest value at which a good sleep state is obtained, the good sleep state is maintained.

  In the present embodiment, step 141 and step 142 are employed in parallel as step 14, but only step 141 may be employed as step 14. However, smooth awakening can be obtained more effectively when the steps 141 and 142 are performed in parallel.

  The sleep control method described in this embodiment includes both an environment control method before and after falling asleep and an environment control method before and after waking, but may include only one of the control methods. .

  According to the sleep control method including only the control method of the environment before and after falling asleep, even if the sleep time is advanced in order to adjust the biological rhythm, the environment temperature is lowered after promoting sleep, so good sleep The state can be obtained.

  Further, according to the sleep control method including only the control method of the environment before and after awakening, when the awakening time is advanced in order to adjust the biological rhythm, even if drowsiness remains after awakening, the drowsiness can be weakened. . Further, by increasing the environmental temperature and promoting awakening before awakening, it is possible to smoothly lead to awakening.

Second embodiment.
In this embodiment, the sleep time is delayed and the sleep time is lengthened. For example, it is desirable to apply when it is necessary to make sleep time 8 hours or more. FIG. 3 is a flowchart showing the sleep control method according to the present embodiment. The sleep control method includes steps 21 to 25.

  In step 21, sleep is inhibited in order to delay the sleep time. Examples of methods for inhibiting sleep onset include the following. In the first method, the human body temperature is kept constant, for example, by keeping the ambient temperature constant from the time point that is a predetermined period after the scheduled time of sleep to the time point of sleep. For example, if the body temperature is kept constant, a moderate warmth or the like that is felt when the body temperature rises is less likely to occur, so that a person is less likely to sleep.

  The second method provides a person with light having an illuminance and a color temperature having a stimulating effect from a time point that is a predetermined period after the scheduled time of sleep to a point of sleep. For example, a person is given light with an illuminance of 2500 lux or more and a color temperature of 5000K or more. Light with an illuminance of 2500 lux or more makes people feel the brightness of the surroundings. In addition, light having a color temperature of 5000K or higher has a bluish color and makes people feel chilly through vision.

  In the first and second methods described above, the time point that is a predetermined period after the scheduled sleep time is set each time depending on how much the sleep time point is delayed.

  One of the first and second methods may be adopted as step 21, or both may be adopted and performed in parallel.

  According to the first and second methods, falling asleep is inhibited. That is, the biological rhythm is adjusted by delaying the time of sleep.

  In parallel with the first or second method, a scent may be given to a person from a time point that goes back a predetermined period from a scheduled sleep time to a sleep time point. For example, scents such as peppermint, caffeine or basil are given to a person. This gives the person a refreshing feeling.

  In addition, a person may be allowed to listen to music from a time point that goes back a predetermined period from a scheduled sleep time to a sleep time point. For example, let people listen to uptempo music such as rock and pop. This makes the person feel better.

  By these methods, inhibition of falling asleep can be assisted. In other words, sleep inhibition is made more effective by performing in parallel with the first or second method.

  In the method of giving scent and the method of listening to music as described above, the time point that is a predetermined period after the scheduled sleep time is set each time depending on how much the sleep time point is delayed. This setting may be associated with the first and second methods or may be performed independently.

  In step 22, after falling asleep, the environmental temperature is decreased, for example, monotonously, for a predetermined period. FIG. 4 shows the change in the environmental temperature with respect to the sleep time as a solid line 221. The solid line 221 includes solid lines 221a, 221b, and 221c. A solid line 221a indicates a change in the environmental temperature after falling asleep due to the environmental temperature control in step S22. A solid line 221b indicates a change in the environmental temperature after the environmental temperature reaches the minimum value due to the environmental temperature control in step 23 described later. A solid line 221c indicates a change in the environmental temperature before awakening due to the environmental temperature control in step 24 described later.

  The environmental temperature indicated by the solid line 221a is set to 29 ° C. during sleep. Thereafter, about 90 minutes is adopted as the predetermined period, and the environmental temperature is monotonously lowered to about 28 ° C. during this period. As the environmental temperature decreases, the human body temperature also decreases. Such an environmental temperature control method is disclosed in, for example, Patent Document 4.

  Since the body temperature is lowered in Step 22 after Step 21 for inhibiting sleep onset, it is possible to lead to a good sleep state.

  In step 23, after the environmental temperature reaches the minimum value by the control in step 22, the environmental temperature is held at the minimum value. The change in the environmental temperature controlled in step 23 is indicated by a solid line 221b in FIG. The ambient temperature is held at a minimum value of 28 ° C. for about 330 minutes.

  In step 24, the surrounding environment of the person before awakening is controlled. Step 24 includes a step 241 for increasing the ambient temperature in a predetermined period, for example, a monotonous increase, and a step 242 for inhibiting arousal before the scheduled awakening time.

  The change in the environmental temperature controlled in step 241 is indicated by a solid line 221c in FIG. The environmental temperature adopts about 90 minutes as a predetermined period, and is monotonously increased from the minimum value of 28 ° C. to 29 ° C. in this predetermined period. After a predetermined period of time, awakening occurs. In addition, as the environmental temperature increases, the human body temperature also increases.

  The contents of step 241 can be grasped when the environmental temperature is increased in a predetermined period from a point in time preceding the predetermined period from the scheduled awakening time.

  In step 242, in order to inhibit arousal, a person is provided with light having an illuminance and a color temperature having a calming effect from a time point that is a predetermined period after the scheduled awakening time to the awakening time point. For example, a person is given light having an illuminance of about 500 lux and a color temperature of about 1000K 30 minutes before the scheduled awakening. Light with an illuminance of about 500 lux makes people feel the dimness of the surroundings. In addition, light with a color temperature of about 1000K is reddish and makes people feel warm through vision.

  In parallel with step 242, the person may be given a scent from the time point awakened by a predetermined period from the scheduled time point for awakening to the point of awakening. For example, a scent of lavender, chamomile or orange is given to a person 30 minutes before the scheduled awakening. This makes people feel relaxed and sleepy.

  Moreover, you may let a person listen to music from the time of going back for a predetermined period from the time of awakening to the time of awakening. For example, a person can listen to music containing a lot of α waves or music with a healing effect 30 minutes before the scheduled awakening. This makes people feel relaxed and sleepy.

By these methods, inhibition of arousal can be assisted. That is, by performing in parallel with step 242, the inhibition of arousal is made more effective.

  In step 25, as in step 15 described in the first embodiment, the sleepiness after awakening is weakened by giving the person light having an illuminance and a color temperature having an excitatory action. This embodiment is preferably applied when the sleeping time is 8 hours or longer, and in this case, sleepiness is often already weakened after awakening. Therefore, even when step 25 is not provided, the following effects can be obtained similarly.

  According to the sleep control method described above, even when the sleep time and awakening time are delayed in order to adjust the biological rhythm, the environmental temperature is lowered after inhibiting sleep, so that a good sleep state can be obtained. In addition, even if it becomes easy to wake up during sleep, the wake-up is inhibited, so that the sleep state can be maintained until the wake-up time.

  Moreover, since the environmental temperature is held at the minimum value after the environmental temperature is monotonously lowered to the lowest value at which a good sleep state is obtained, the good sleep state is maintained.

  The sleep control method described in this embodiment includes both an environment control method before and after falling asleep and an environment control method before and after waking, but may include only one of the control methods. .

  According to the sleep control method including only the control method of the environment before and after falling asleep, even if the sleep time is delayed in order to adjust the biological rhythm, the ambient temperature is lowered after inhibiting sleep, so good sleep The state can be obtained.

  In addition, according to the sleep control method including only the environmental control method before and after awakening, when the awakening time is delayed in order to adjust the biological rhythm, the awakening is inhibited even if the state becomes easy to awaken during the sleep. Therefore, the sleep state can be maintained until the awakening time.

  In any of the above-described embodiments, the sleep control method can be employed in the sleep control device. FIG. 5 conceptually shows the sleep control device according to the present embodiment. The sleep control device 5 includes a control unit 51, a temperature adjustment unit 52, an acoustic unit 53, a scent generating unit 54, and a light emitting unit 55. The acoustic unit 53 is, for example, a speaker. The scent generating part 54 is, for example, an electric aroma machine. The light emitting unit 55 is, for example, an LED (Light Emitting Diode).

  Before going to sleep (step 11 or step 21), before waking up (step 142 or step 242), and after waking up (step 15), the control unit 51 controls the light emitting unit 55 to have a predetermined illuminance and color temperature. Light is given to a person for a predetermined time.

  In addition, before entering a sleep state and before waking up, in parallel with the control of the light emitting unit 55, the scent generating unit 54 is controlled to give a person a predetermined scent at a predetermined generation amount and a predetermined time. Alternatively, the sound unit 53 is controlled to allow a person to listen to a predetermined type of music at a predetermined volume and a predetermined time.

  From the time of falling asleep to the time of awakening (steps 12, 13, 141 or steps 22, 23, 241), the temperature adjustment unit is controlled to adjust the environmental temperature.

  According to the sleep control device 5 described above, at the time of falling asleep, in order to adjust the biological rhythm, when the sleep time is advanced, the sleep is promoted, and when the sleep time is delayed, the sleep is inhibited, and the environment is changed after the sleep. Since the temperature can be lowered, a good sleep state can be obtained.

  At the time of awakening, since the environmental temperature can be raised before awakening, it can be smoothly led to awakening. And when awakening time is advanced, it can lead to awakening more smoothly by giving a person the light which has the illuminance and color temperature which have excitement action. In addition, when delaying the awakening point, by giving the person a light with a calming illuminance and color temperature, even if it becomes easy to awaken during sleep, it can inhibit the awakening, The sleep state can be maintained until awakening. After waking up, by giving a person a light having an illuminance and a color temperature having an excitatory effect, drowsiness can be weakened even when sleepiness remains.

  The sleep control device 5 described above may include only the control unit 51, the temperature adjustment unit 52, and the light emitting unit 55. However, the provision of the scent generating part 54 or the sound part 53 more effectively assists the promotion or inhibition of falling asleep before falling asleep and the promotion or inhibition of awakening before awakening.

  When the environmental temperature is increased in the first predetermined period in step 11 and the environmental temperature is decreased in the second predetermined period in step 12, the sleep control device 5 includes only the control unit 51 and the temperature adjustment unit 52. May be provided. According to the sleep control device 5, the same effect as that of the first embodiment can be obtained.

  When the environmental temperature is kept constant in the first predetermined period in step 21 described above and the environmental temperature is decreased in the second initial period in step 22, the sleep control device 5 includes the control unit 51 and the temperature. Only the adjustment unit 52 may be provided. According to the sleep control device 5, the same effect as that of the second embodiment can be obtained.

Deformation.
Step 14 shown in FIG. 1 may be replaced with step 24 shown in FIG. 3 to perform sleep control. In this case, while falling asleep is promoted, awakening is inhibited. Similar to the second embodiment, the sleep time is lengthened, but unlike the second embodiment, the sleep time is not delayed.

  For example, before going to sleep, step 11 (FIG. 1) that promotes falling asleep is performed, and after sleeping, step 12 is executed (FIG. 1), and as shown by a solid line 122a (FIG. 2), for a predetermined period, Reduce temperature. Then, step 241 (FIG. 3) is executed, and as shown by a solid line 221c (FIG. 4), the environmental temperature is increased in a predetermined period from a time point that is a predetermined period after the awakening scheduled time after falling asleep. Alternatively, step 242 (FIG. 3) may be executed to inhibit arousal.

  Conversely, sleep control may be performed by replacing step 24 shown in FIG. 3 with step 14 shown in FIG. In this case, while falling asleep is inhibited, awakening is promoted. Although the sleep time is shortened similarly to the first embodiment, the sleep onset time is not advanced unlike the first embodiment.

  For example, before falling asleep, step 21 (FIG. 3) that inhibits falling asleep is performed, and after falling asleep, step 22 is executed (FIG. 3), and for a predetermined period as shown by the solid line 221a (FIG. 4), Reduce environmental temperature. Then, step 141 is executed, and as shown by the solid line 122c (FIG. 2), the environmental temperature is increased in the predetermined period from the time point that has gone back the predetermined period from the scheduled time of awakening. Step 142 (FIG. 1) may be executed to promote arousal.

  Of course, in any of the above two variations, as shown by the solid line 122b (FIG. 2) and the solid line 221b (FIG. 4), the environment temperature reaches the minimum value until the environment temperature is increased. It is also desirable to keep the temperature at a minimum value.

  The sleep control according to the above-described deformation can also be realized using the sleep control device shown in FIG.
