Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to light stimulation and temperature stimulation.
The present invention relates to a biological rhythm activation device that can activate a circadian rhythm by effectively and efficiently giving it to a living body, and can prevent a habit of living without being preoccupied.

[0002]

2. Description of the Related Art Human rhythm (circadian rhythm)
There are two groups of oscillators, a deep body temperature rhythm affected by the light-dark cycle and a sleep-wake rhythm affected by social entrainment factors, and usually the two oscillators maintain a constant phase relationship. There is. However, when a free run (internal desynchronization) occurs in two rhythms in their own cycles, loss of deep sleep, general malaise and loss of appetite are often complained, and work efficiency is also reduced. . In addition, when the amplitude of the body temperature rhythm is relatively small, there is no swelling during the awakening period and the sleeping period of daily life, and energy loss and discomfort occur.

Further, there is an interaction between the two vibrating bodies, and rather than the effect of the sleep / wake rhythm on the body temperature rhythm,
It is said that the effect of body temperature rhythm on sleep-wake rhythm is greater. Therefore, it is important to adjust the body temperature rhythm so that the body temperature rhythm and the sleep-wake rhythm are synchronized and the amplitude of the body temperature rhythm is increased. Therefore, it is said that the body temperature rhythm can be reset by being exposed to high illuminance light or light having a certain wavelength characteristic, and is usually synchronized with the subjective wake-up light. Further, it is known that the amplitude of the body temperature rhythm can be increased or decreased by a light irradiation method or an appropriate temperature stimulus.

In the conventional technique of this kind, the phototherapy device disclosed in Japanese Patent Laid-Open No. 302302/1990 efficiently controls the blinking of a light source having a wavelength characteristic matching a biological rhythm curve by a timer and a control unit. It has an enhanced therapeutic effect, and was generally invented for medical treatment for treating symptoms caused by disturbance of biological rhythm such as sleep disorder and seasonal affective disorder.

Further, the biological rhythm adjusting device described in JP-A-5-3919, JP-A-5-3920 or JP-A-5-3874, or JP-A-5-15559.
The biorhythm control system, etc. described in the publication makes it possible to respond to the difference in the reactivity of individual stimuli by inputting the biorhythm of the individual, and it also controls the environment by inputting environmental information. There is also disclosed a biological rhythm control device in which a stimulus (including a temperature stimulus) other than light that gives a change or an awakening level is also considered.

[0006]

First of all, it is necessary to consider a review of the indoor environment, especially for people who are forced to live indoors or who are more likely to live indoors. . For example, in the body temperature rhythm in a nursing home that people spend all day indoors, it has been reported that in the case of bedridden elderly, the deep temperature level is high and they cannot sleep deeply, and indoors without going out. It is known from life experience that bedtime is gradually delayed when spending time.

[0007] Considering the stimulus for the biological rhythm, which tends to be insufficient in the indoor environment, temperature stimulus can be considered in addition to the high illuminance light. First, if the light stimulus is insufficient, indoors may be blocked due to high-intensity outdoor sunlight, bad weather, seasonal fluctuations of solar radiation, or rising and falling sunsets. In some cases, it may not be possible to receive sufficient light and receive high illuminance light.

One of the reasons for lack of thermal stimulation is that the temperature is controlled within a comfortable temperature range by an air conditioner or the like in order to maintain comfort in an indoor environment, so that there is little change in heat. That's what it means. Also, it is necessary to consider the case where even a healthy person cannot receive sufficient light and temperature stimuli to help stop the biological rhythm when waking up due to seasonal variations and differences in weather conditions.

For example, discomfort due to insufficient solar radiation on a cloudy day and inactivity after waking up due to delay of sunrise in winter or reduction of solar radiation amount can be cited. Therefore, it is necessary to consider preventing the above-mentioned decrease in activity and discomfort by providing light stimulation and temperature stimulation in cooperation with each other efficiently and effectively.

[0010] However, the "phototherapy device" of the prior art is intended to give a light stimulus in accordance with the diurnal cycle, but the temperature stimulus is not taken into consideration. Further, the "biological rhythm adjustment device" and the "biological rhythm control system" measure and evaluate individual biological rhythms and reflect them in the device control. However, the individual biological rhythm measuring means evaluates the biological rhythms. Therefore, it is necessary to grasp accurately.

However, on the assumption that the disturbance of the biological rhythm is to be prevented, considering the adjustment of the body temperature rhythm according to the sleep-wake cycle in the daily social life of 24 hours a day, the daily routine is considered. There is not much need to measure individual biological rhythms in life. In addition, it is very difficult to carry the sensor with you every day in your daily life, and it is thought that the cost will be high because the system is large and the device scale is large. Is difficult

[0012] Further, in the prior art, there are some which use temperature stimulation as a stimulus other than the light stimulus to change the arousal level, but in the concretely described example, a hot shower is taken in the morning. There is no system that links optical stimulus and thermal stimulus, for example, by changing the air conditioning according to the condition of daily diurnal variation.

The biological rhythm activation device of the present invention has been made in view of the above problems, and is premised on preventing various symptoms that may be caused by the disturbance of the biological rhythm, especially after waking up. To attach a sensor to the human body by giving light stimulation and temperature stimulation effectively and efficiently within 3 hours before bedtime, and by giving more efficient stimulation by incorporating environmental information around humans. Instead, the purpose is to control the device only from information such as personal sleep / wake information and environmental information.

Since the biological rhythm is changed by stimuli such as temperature stimulus and light stimulus, it can be widely used by people with physical disabilities, bedridden people and healthy people.

[0015]

A biological rhythm activation device according to the present invention solves the above-mentioned problems.
The invention described is a time setting means for setting a desired wake-up time and bedtime, a wake-up time set by the time-setting means, a time-delaying means for generating a signal at bedtime, and a light that activates a living body by optical stimulation. Stimulation means, temperature stimulation stimulation means that activates the living body by temperature stimulation, illuminance measurement means that measures the illuminance near the human body or outdoor illuminance in response to a timed signal, and heat that measures the thermal environment around the human body. An environment measuring unit, a light control unit that controls the light stimulating unit according to the illuminance measured by the illuminance measuring unit, and a temperature control unit that controls the temperature stimulating unit according to the thermal environment measured by the thermal environment measuring unit. It is composed of.

According to a second aspect of the present invention, in the biological rhythm activation device according to the first aspect, there is provided a going-out input means for inputting whether or not the person is going out, and when the person is going out, the outdoor illuminance is measured, It is configured so that the indoor illuminance can be set in advance when there is no going out.

Furthermore, the invention according to claim 3 is, in the biological rhythm activation device according to claim 1 or claim 2, entrance / exit management for checking whether or not a user is present in the controlled space. When the user is not present in the controlled space, the stimulation time is not counted, and the total stimulation time of the optical stimulation and the thermal stimulation to the user is saved, so that the controlled space is controlled. This is a structure that can prevent the lack of stimulation due to leaving the room abruptly.

[0018]

The biological rhythm activation device of the present invention has the above-mentioned structure, and thus the invention according to claim 1 is suitable for a person who cannot receive appropriate optical stimulus or thermal stimulus acting on the biological rhythm. By applying light and temperature stimuli, it is possible to efficiently and easily promote the internal synchronization of biological rhythms and increase the amplitude.

First, by controlling only from the input of sleep / wake cycle information and environmental information of an individual without mounting a sensor on the human body or evaluating a biological rhythm, a simple device is provided and cost is reduced. What you can do,
Since it is possible to give a light stimulus and a temperature stimulus according to environmental information around the human body, a more effective and efficient energy-saving device can be obtained.

The invention according to claim 2 provides the invention according to claim 1.
In addition to the actions described, when going out, the outdoor weather information is taken in, so when going out when the amount of solar radiation is sufficient (in the morning), the sunlight received when going out is a sufficient stimulus. Therefore, since it is considered that the indoor optical stimulation is unnecessary, it is possible to prevent wasteful energy consumption.

Furthermore, the invention according to claim 3 is the same as claim 1.
Alternatively, in addition to the function according to claim 2, by managing the entry / exit of the user in / from the controlled space, by not counting the stimulation time when the user is not in the controlled space. Therefore, it becomes possible to prevent the lack of stimulation due to the exit from the controlled space.

As described above, it is possible to prevent the discomfort due to the insufficient transfer of moderate light stimulation and temperature stimulation.
It's a life-changing thing (I have motivation and energy during the day,
At night, you can sleep immediately and get a deep sleep feeling).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the biological rhythm activation device of the present invention will be described below with reference to the drawings. First, the configuration of the first embodiment of the biological rhythm activation device of the present invention will be described. FIG. 1 is a block diagram showing the configuration of the first embodiment of the biological rhythm activation device of the present invention. FIG. 2 is an explanatory diagram showing an example in which the block configuration diagram of FIG. 1 is specifically incorporated into an indoor environment.

In FIG. 1, 1 is a time setting means,
Enter the wake-up time and bedtime. This is for inputting a desired time as a sleep / wake cycle, and therefore the time setting means 1 is provided with a switch section, a liquid crystal display and the like. Reference numeral 2 denotes a time limit means, which outputs a first time limit signal when the wake-up time input by the time setting means 1 is reached, and the second when a preset time (for example, 30 minutes to 1 hour) before the set bedtime. Of the time limit signal for outputting the appropriate signal to the illuminance measuring means 3 and the thermal environment measuring means 6 according to these predetermined times.

Further, 5 is a light stimulating means, 8 is a temperature stimulating means, and the light stimulating means 5 generates a light source with which the illuminance near the human head becomes a high illuminance light of at least 3000 lx (lux) or more. It is desirable that the lighting system be capable of controlling, and that the artificial lighting device such as a bedroom used in a general household be linked by a control system. The temperature stimulating means 8 is composed of a radiant panel or an air conditioner capable of giving a suitable temperature stimulus to a living body.

Reference numeral 3 denotes an illuminance measuring means which operates in response to a signal emitted from the time delay means 2 to measure the illuminance around the human body (near the human head) or the illuminance outdoors, and measures the illuminance with an illuminometer. In addition, 6 receives a signal emitted from the time delay means 2 to generate a thermal environment (temperature,
Humidity, radiation, wind speed, etc.) and a thermal environment means for measuring thermal information (clothing amount, activity amount) on the human body side, such as temperature sensor, humidity sensor, radiation temperature sensor, wind speed sensor, clothing amount sensor, activity amount sensor. And so on.

Further, each control unit of the light control unit 4 and the temperature control unit 7 is composed of a microcomputer and a drive circuit which operates according to its command, and the light control unit 4 measures the illuminance measured by the illuminance measuring means 3. The temperature control unit 7 controls so as to give a thermal stimulus according to the thermal environment measured by the thermal environment measuring means 6, and the optical stimulating means 5 and the temperature stimulating means. The operation of 8 is automatically stopped when a predetermined time elapses.

The configuration of FIG. 1 will be described more specifically with reference to FIG. 2. The time setting input 1A is the time setting means 1 of FIG.
1, the time limit signal 2A is the time limit means 2 in FIG. 1, the illuminance sensor 3A is the illuminance measuring means 3 in FIG. 1, and the high illuminance lighting device 5A and the indoor lighting equipment 5B are the light stimulating means 5 in FIG. The thermal environment measuring sensor 6A is the thermal environment measuring means 6 in FIG. 1, and the air conditioner 8A is the temperature stimulating means in FIG.

Here, the effects of light stimulation and temperature stimulation that act on the biological rhythm will be described. First, regarding light stimulation,
The normal 24-hour cycle body temperature rhythm reaches a maximum point in the evening and becomes a minimum point during sleep, which is a substantially sinusoidal rhythm. Therefore, when you wake up, the body temperature rises smoothly,
The smooth decrease in body temperature at bedtime causes the phases of the daily biological rhythms to be synchronized and the amplitude to increase.

Therefore, it is said that the body temperature rhythm is synchronized with the light-dark cycle, and that the synchronization with the 24-hour cycle is said to be performed by subjective morning light, and that the pineal gland is exposed when exposed to high-intensity light. Since the body temperature tends to rise due to the suppression of the hormone melatonin, it is very meaningful to receive light stimulation within about 3 hours after waking up (subjective morning). In addition, by reducing the illuminance on the subjective night (before going to bed), the body temperature can be lowered more smoothly.

Next, with respect to the temperature stimulus, it is possible to raise or lower the body temperature to some extent by an appropriate temperature stimulus (stimulus that is neither too hot nor too cold and is not extremely unpleasant). When a living body is subjected to temperature stimulation, venous blood vessels on the peripheral skin surface expand, and venous blood returns to the core while radiating heat to the outside world. The temperature of the returning venous blood is considered to be lower than the core temperature, resulting in a decrease in core temperature.
Also, when cold stimulation is applied, venous blood vessels on the peripheral skin surface contract.

The warm arterial blood flowing from the central part gives heat to the venous blood flowing from the peripheral part to the central part until the peripheral part is erased, and the heat dissipation amount in the peripheral part is saved. The venous blood is thus warmed by the arterial blood and returns to the core, so that cooling of the core is prevented. The biological reaction to the above temperature stimulus is called countercurrent heat exchange.

However, there is a limit to this mechanism, and if a very hot temperature stimulus is given, the body temperature will rise on the contrary, and a very cold stimulus may lower the body temperature. As a moderate temperature stimulus, it is desirable when the environment is in a region that is thermally close to a neutral condition. Further, moderate cold stimulation in the morning may stimulate the skin and tension the sympathetic nerves, so that awakening also becomes smooth, and warm stimulus before sleep may relax the sympathetic nerves, resulting in a sleepy state.

By utilizing this mechanism, it is possible to help the rhythm lowering after waking up by giving an appropriate cold stimulus after waking up, and by giving a warm stimulus to the peripheral before bedtime, It can help the body temperature drop smoothly. It is desirable to give such a temperature stimulus.

Then, what happens when the above-mentioned optical stimulation and thermal stimulation are combined and applied will be described with reference to FIG. FIG. 3 shows a diurnal rhythm of a body temperature of a subject, which is a comparison of three conditions in which daytime environmental conditions are changed.
All other conditions are the same.

First, HALF is a short-sleeved shorts for day and night (cl
(o value = about 0.4), LONG spent long day long-sleeved trousers (clo value = about 0.7), and LIGHT was up from 6:30 to 9:30 for 3 hours. When exposed to light of about 1500 Lux, the clothing type is the same as HALF. In all three conditions, the wake-up time in the sleep-wake cycle is 6:00 am and the bedtime is 22:
00, one day spent in the laboratory, where all three conditions were kept at a room temperature of 26 ° C. and a constant humidity of 50% to maintain a thermally comfortable environment.

As is clear from FIG. 3, LIGHT, which means that the optical stimulus and the thermal stimulus are simultaneously given immediately after waking up.
Then, it can be seen that the rise in body temperature in the morning is the largest. Also, at night, the room is turned off 30 minutes before bedtime, and only the stand light at hand is turned on.
At 2:00, all the lights are turned off. The clothing type at night is standardized to HALF for all three conditions so that only differences in living conditions at daytime can be compared. Then, when I focused on night time, it was still LIGHT
It can be seen that is the biggest decrease in body temperature.

From the above, it can be seen that the greater the increase in body temperature during awakening, the greater the decrease in body temperature during sleep, which means that the difference in daily life affects sleep at night. Suggest. Usually, the body temperature reaches its highest point around the evening and then gradually falls to the lowest point near the second half of the sleep time. It is suggested to induce the induction, and it is also suggested that the deeper the body temperature during sleep is, the deeper the sleep is obtained. Therefore, from this, it is activated during the daytime awakening period,
Being able to sleep deeply during the night's sleep makes it possible to focus on daily life.

Here, FIG. 4 shows the relationship between the PMV (ISO standard) value of the thermal environment index obtained from the heat balance equation between the human body and the environment, the amount of clothing, and the room temperature (= radiation temperature). The vertical axis represents the PMV value, the horizontal axis represents the room temperature (= radiation temperature), and the straight line indicates the clothing amount (0.1 to 0, 1 to 4 cm).
It has been crushed). At this time, other parameters (humidity, wind speed, activity amount) are the case where the setting conditions and approximate values in the experiment of FIG. 3 are input. In addition, in the experiment of FIG. 3, the amount of clothes (black value) at the time of HALF is about 0.4 cl.
and the amount of clothing (black value) when LONG is about 0.7
It becomes clo.

Therefore, as shown in FIG. 4, when the room temperature is 26 ° C., the PMV value is about −0.25 when the black value is 0.4, and the PMV value is +0.4 when the black value is 0.7. Become.
Therefore, in order to obtain the PMV value (-0.25) of HALF which seems to be an appropriate cold stimulus with LONG, the room temperature (radiation temperature = room temperature) may be set to about 24 ° C. Therefore, by controlling the air conditioner so that the PMV value becomes 0 to -0.3 on the slightly cool side as described above, an appropriate cold stimulus can be obtained. The dissatisfaction rate PPD in this range is about 5 to 6.2%, which is not a problem.

Next, specific examples will be described in more detail. First, by inputting a desired wake-up time and bedtime in the time setting means 1, information on the sleep / wake cycle according to an individual's social life is obtained. The purpose is to adjust the phase and increase the amplitude of the body temperature rhythm that matches this sleep-wake cycle. Therefore, first, the stimulus when waking up will be described.

When the wake-up time input by the time setting means 1 is reached, the time delay means 2 issues a first time delay signal. In response to the signal emitted from the time delay means 2,
The illuminance measuring means 3 and the thermal environment measuring means 6 operate. Explaining the illuminance measuring means 3 here, in the case of a person who spends most of his daily routine indoors, a place located near the human head inside the room (for example, in the case where the posture during light irradiation is a person with many standing positions) Attached to a wall located near the standing head, in the case of many sitting people, at a height near the sitting head, and in the case of a person who is exposed to the light while lying down, a wall located near the recumbent head ,
The illuminance sensor 3A is attached to the bedside) in advance and the illuminance near the human head is measured.

This is to try to effectively utilize natural energy by being able to cope with the change in the amount of natural light collected from the windows due to changes in seasons and weather conditions. In addition, a person who can go outdoors can effectively use outdoor sunlight by installing a sensor on the roof of a building or the like and measuring the outdoor illuminance.

First, the light that acts on the human biological rhythm is
It is said that high illuminance light of 2,500 lx or more is required as the illuminance, and if the illuminance is high, it is considered that the effect appears in a short irradiation time. Therefore, the illuminance of sunlight is about 100,000 lx at noon on a clear day in June and about 1,000 to 10,000 lx on a cloudy day, so that the illuminance measured by the illuminance measuring means 3 is 2,50.
When it is 0 lx or less, it is desirable that the light stimulation control means 4 controls the light stimulation means 5 to operate. Also,
10,000 even if the illuminance is 2,500 lx or more
In the case of 0 lx or less, the effect does not appear when the irradiation time is relatively short, so it is necessary to consider it.

Therefore, when utilizing this solar energy, it is desirable to respond according to the situation on the side of the user. For example, a possible user is a bedridden elderly person or a sick person who does not go out outdoors, a person who usually goes out outdoors, or a person who usually goes out but has a short outing time. For example, time. Therefore, first, in the case of a person who usually does not go out outdoors, the illuminance sensor is installed in advance in a place where the illuminance near the head of the user in the room can be measured. And the measured illuminance is 2,5
When it is 001x or less, the photostimulation means is controlled to be activated.

For a person who usually goes out outdoors, it is desirable to install an illuminance sensor outdoors (on the roof, etc.) to measure the illuminance outdoors and at the same time measure the illuminance indoors. Then, when the outdoor illuminance is 2,500 lx or less, the photostimulation means is controlled to operate. However, the time for going out is within 3 hours after waking up, and when going out after 3 hours or more after waking up, the light stimulation is activated when the illuminance in the room is 2,500 lx or less.

If the time of going out is short (30 minutes or less), it is considered that the effect of the high illuminance light is not obtained even if going out, so that the outdoor illuminance is 10,000 l.
If it is less than or equal to x, the light stimulus is activated. Settings such as whether the time to go out is within 3 hours or more than 3 hours after waking up, and whether the time to go out is short or long is determined in advance from a normal life cycle or manually input. , Make settings that match the life cycle of the individual.

Therefore, the optical stimulation control means 4 will be described next. The light stimulus control unit 4 determines whether to activate the light stimulus unit according to the illuminance measured by the illuminance measuring unit 3,
Then, when it is decided to operate, the light stimulation control means 4
Starts to operate and controls the photostimulation means 5. Light stimulation means 5
Is a high illuminance light, so it is desirable to gradually increase the illuminance in consideration of the visual sense of the user.

Then, the illuminance is gradually increased over a period of about 10 minutes to reach the target illuminance, and the illuminance is maintained for a predetermined time (30
The target illuminance is maintained, and the light is automatically turned off after a certain period of time. Also, when turning off the light, it is desirable to gradually decrease the illuminance over about 10 minutes in consideration of the visual sense of the user. The irradiation time of light differs depending on the illuminance of the light to be irradiated.

Therefore, for example, there is time available in the morning (usually living indoors, for example, bedridden elderly, sick and the like).
In the case of 3,000 lux for about 3 hours, and if you are busy in the morning and do not have enough time (there is no leeway in the morning due to commuting to work or school)
Irradiation is performed for 30 minutes at 10,000 lx.

The light stimulating means 5 is an illuminating device capable of providing an illuminance of 3,000 lx or more at least near the human head. If the distance from the light source to the position near the head of the human body is too large, the lighting device becomes large-scaled. Therefore, horizontal wall installation or stand installation is preferable to installation on the ceiling or the like. For example, an illuminance of 3,000 lx can be obtained about 1 m away from the light source of eight 40 W fluorescent lamps. Ordinary artificial lighting (300-500)
lx) is also linked to the control system.

Next, the method of temperature stimulation will be described. In the thermal stimulus, first, similarly to the optical stimulus, the thermal environment measuring means 6 is activated by the first signal emitted from the time delaying means 2, and the thermal environment measuring means 6 measures the thermal environment in the room. Therefore, first, a supplementary explanation will be given regarding the thermal environment.

PMV is an ISO standard as a thermal environment evaluation index for the human body. This PMV is a heat balance equation of the human body,
The comfort zone is defined as 0 when the environment side and the human body side are in thermal equilibrium. Temperature, air flow, radiation as thermal environment elements
There is humidity, and the amount of clothing and activity are elements of the human body.
The index is shown in the range of -3 (cold) to +3 (hot), and 0 is the neutral comfort region, and the dissatisfaction rate PPD at this time is about 5%. And the temperature stimulus is
It is considered that the negative stimulus becomes a cold stimulus and the positive stimulus becomes a warm stimulus when the heat balance is reached. However, here, the body temperature drops in extreme cold exposure, and rises in extreme heat exposure. Here, in the morning cold stimulus, the temperature of the room which is not air-conditioned in winter is sufficiently lowered, so in the morning, it is rather difficult to get up.

Therefore, it is necessary to consider an environment in which it is easy to wake up according to environmental changes, and it is desirable to provide a cold stimulus on top of it. For example, assuming that a person who mainly spends time indoors lives in a comfortable room that is air-conditioned all day long, the air-conditioner is controlled so as to feel slightly cooler than neutral. At this time, it is desirable to change it according to the heat information (clothing amount, activity amount) on the human side. Specifically, the PMV value is set to 0 by changing each variable in the above-mentioned PMV.
It is desirable to change the room temperature or the radiant temperature mainly by controlling the air conditioner so that the temperature becomes to -0.3.

The temperature stimulating means 8 is capable of giving an appropriate temperature stimulus, and is composed of an air conditioner, a radiation panel or the like capable of air conditioning the entire room or local air conditioning.

Therefore, next, the stimulation before going to bed will be described.
When a certain time before going to bed (for example, 30 minutes to 1 hour), a second signal is emitted from the time delay means 2, and in response thereto, the light control means 4 and the thermal environment measurement means 6 are activated. The light control means 4 controls the illuminance of an artificial lighting device that is normally used indoors. First, when a signal is received from the time delay means 2, the illuminance is gradually reduced by the time the bedtime is set, and a light environment in which it is easy to fall asleep at the bedtime is set. Further, the thermal environment measuring means 6 measures the thermal environment and controls the temperature stimulating means 8 (air conditioner, radiation panel, etc.) according to the thermal environment information.

The warm environment at bedtime causes sleep disorders such as cold limbs that make it difficult to sleep in the winter, and hot in the summer, which makes it difficult to sleep. It is intended to provide a thermal environment to improve such a situation. Therefore, a comfortable thermal environment (P
MV = 0 to 0.3).

FIG. 5 is a block diagram showing the configuration of the second embodiment of the biological rhythm activation device of the present invention. FIG. 5 shows that the biological rhythm activation apparatus according to the first embodiment is provided with the going-out input means 9 so that for a person who may go out outdoors in normal life, within about 3 hours after waking up tomorrow. You can measure the outdoor illuminance in advance by entering whether to go out to
It is shown that appropriate control can be performed by deciding whether to measure indoor illuminance.

FIG. 6 is an explanatory diagram showing an example in which the block diagram of FIG. 5 is specifically incorporated into the indoor environment.

Further, FIG. 7 is a block diagram showing the configuration of the third embodiment of the biological rhythm activation device of the present invention.
FIG. 7 shows that, in the bioactive device according to the first embodiment, the user has to stay in the controlled space for a certain period of time for light stimulation and temperature stimulation after waking up, but during or immediately after waking up. In addition, if you have to leave the controlled space temporarily, the stimulus during exit is wasted, and
Since there is a case where the amount of stimulation is insufficient for the user, the entrance / exit management means 10 is provided there to check the entry / exit, and by controlling and managing so that the stimulation time is not counted during exit, It is possible to save energy and prevent a shortage of stimulation when going out temporarily. The room entering / exiting check method here can be performed by an image processing technique using a CCD camera or the like.

EFFECT OF THE INVENTION Since the biorhythm activation device of the present invention has the above-mentioned constitution, the invention according to claim 1 is suitable for one day of light stimulus and temperature stimulus acting on the biorhythm (circadian rhythm). For people who are indispensable to receive the stimuli, it is possible to increase the amplitude of the body temperature rhythm by efficiently and easily promoting the internal synchronization of the biological rhythm by artificially applying appropriate light and temperature stimuli. And Further, it is possible to obtain the sleep / wake cycle information of an individual by inputting the desired wake-up time and bedtime, and the environment information around the user by the light measuring means and the thermal environment measuring means. Therefore, the temperature stimulus and the light stimulus are controlled only by the sleep / wake cycle information and the environmental information, and the device becomes a simple device and the cost can be reduced. Since it is possible to give a light stimulus and a temperature stimulus according to environmental information near the human body, a more effective and efficient energy-saving device can be obtained. If you go out further, since the outdoor weather information is taken in, when you go out when the amount of solar radiation outside is sufficient (in the morning), the sunlight received when you go out is a sufficient stimulus, so the indoor light Since it is considered that stimulation is unnecessary, it is possible to prevent wasteful energy consumption.

The invention described in claim 2 is the same as claim 1

By doing so, when the user is absent in the controlled space, by not counting the stimulation time, it becomes possible to prevent the stimulation from being insufficient due to the exit from the controlled space.

As described above, it is possible to prevent the discomfort due to the insufficient transfer of moderate light stimulation and temperature stimulation.
It's a life-changing thing (I have motivation and energy during the day,
It has the effect of giving activity during the day such as sleeping at night and getting a deep sleep feeling.
