Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sleep environment control device for controlling an environment in which a user sleeps, and particularly to a sleep environment control device capable of providing a comfortable and beneficial sleep environment for a woman. .
[0002]
[Prior art]
The physical condition that appears in a woman's monthly cycle has a close relationship with basal body temperature. As shown in Fig. 10 of the accompanying drawings, the basal body temperature changes from the low temperature period to the high temperature period on the ovulation day. It is known that the transition from the high temperature period to the low temperature period starts at the start date. Conventionally, by using this relationship, a physical condition appearing in a woman's monthly cycle has been determined by measuring and recording the transition of the basal body temperature when waking up each morning with a basal thermometer for women.
[0003]
Furthermore, this one-month physical condition of the woman is generally explained during the menstrual period, after menstruation, after ovulation, and before menstruation. Actually, there is a slight change in mind and body during each period. Said. In particular, during menstruation from before menstruation, it is easy to store water and fat in the body, and depending on the person, it is said that the body weight increases from about 1 to 3 kg than usual.
[0004]
One week before menstruation is also called PMS (Premenstral Syndrome) period, and many women suffer from some unpleasant symptoms such as headache, irritability, abdominal pain, swelling. Furthermore, during this period, comfortable sleep cannot be obtained due to the above-mentioned symptoms, and fatigue is difficult to accumulate.
[0005]
Even at this time, even if exercise and dietary restrictions are used to reduce weight, stress is likely to accumulate and the efficiency is low, and the reaction also causes more than usual eating and drinking. It is said that there is.
[0006]
In addition, it is said that in order to alleviate unpleasant symptoms in the PMS stage, it is better to recognize that the person is in that state and to catch positively that the symptoms are evidence of health.
[0007]
[Problems to be solved by the invention]
In the conventional physical condition judgment of a woman based on the transition of basal body temperature, the basal body temperature must be measured usually taking about 5 minutes in a lying-down position when getting up every day. This is very troublesome and also causes the person to be judged to sleep again during measurement and to oversleep.
[0008]
In addition, women's physical condition judgment based on changes in basal body temperature can determine the date of ovulation, menstrual period and fertile period, which are mainly used for berth control. It is not possible to determine the PMS (Premenstrual Syndrome) stage, which is increasingly recognized as. During the PMS period, which begins about 7 days before the start of menstruation, many women suffer from some unpleasant symptoms such as headache, irritation, abdominal pain, swelling, and they realize that they are in the PMS period. It is said to be an effective means for alleviating the symptoms.
[0009]
Therefore, the applicant of the present invention has disclosed a female physical condition determination method and a female physical condition determination device for determining a physical condition that appears in a woman's monthly cycle from the transition of bioelectrical impedance, as described in Japanese Patent Application Laid-Open No. 2001-78977. Developed and proposed. This makes it possible to determine not only the menstrual cycle and the presence or absence of ovulation, but also the occurrence of PMS.
[0010]
However, the conventional basal thermometer simply determines the menstrual cycle and the current physical condition from the transition of the measured basal body temperature.
[0011]
Further, the physical condition determination method and the female physical condition determination apparatus described in Japanese Patent Application Laid-Open No. 2001-78977 only determine a female physical condition.
[0012]
On the other hand, women have been actively dieting in recent years. However, this method reduces weight by continuously exercising and restricting meals every day, and is performed without much consideration of the mental state and physical condition of the person. This was a heavy burden on the body during times of upset. In particular, dieting during periods of mental instability is not only counterproductive as described above, but excessive weight loss adversely affects various functions of the body. The gloss of the skin will be lost, the hair will be crumbly, and the nails will be brittle.
[0013]
Even if these symptoms are not reduced, the female body undergoes periodic hormonal changes that occur periodically. However, suffering from such symptoms, excessive intake of foods and medicines that are said to ameliorate the symptoms excessively caused side effects, and more than necessary makeup was returned to cause rough skin .
[0014]
In particular, in the PMS stage, various symptoms appear due to the occurrence of swelling, but there has been no way of grasping the occurrence and degree, and many women have been troubled without measures.
[0015]
The objective of this invention is providing the sleep environment control apparatus which can eliminate the trouble of the prior art as mentioned above, and can provide a comfortable and beneficial sleep environment for a woman.
[0016]

In order to relieve the complaints, the physical condition is relatively good after menstruation and before and after ovulation, and the basal metabolism is high. I am going to do that.
[0027]
Next, an embodiment of the sleep environment control device of the present invention will be described.
[0028]

Of course, these components can be provided at a location different from the operation box 2 in some cases.
[0030]
  FIG. 2 shows a use state of the apparatus shown in FIG. 1, and a user sleeping on the mattress 1 is indicated by a dotted line. in this way,Current supplyElectrodes 3A-3D,Voltage measurementThe electrodes 4A to 4D and the body temperature measurement pad 5 are arranged at positions that come into contact with the respective parts when the user lies in the lying position.
[0031]
FIG. 3 is a block diagram showing a connection relationship of each component of the sleep environment control device including the mattress 1 shown in FIG. As shown in FIG. 3, the current supply electrodes 3A to 3D are connected to a high frequency constant current circuit 8 for applying a weak high frequency constant current. The other voltage measurement electrodes 4A to 4D are connected to a voltage measurement circuit 9 for measuring the voltage drop due to the constant current described above. Further, the pressure sensor 10 performs various functions as will be described later, and as one of the functions, as a body weight measuring means for measuring the body weight as the weight when the user gets on the mattress 1, Fulfills the function. The pressure sensor 10 can generate a pressure signal representing the air pressure in the mattress 1, and the pressure signal from the pressure sensor 10 before the user gets on the mattress 1 and after the user gets on the mattress 1. The weight of the user can be known from the pressure signal from the pressure sensor 10. The voltage measuring circuit 9 and the pressure sensor 10 are connected to a calculation control unit (CPU) 11 which is a calculation means for performing various controls such as conversion from analog values to digital values, menstrual cycle, physical condition determination, heating and air pressure. ing.
[0032]
A display unit 6 and an input device 7 including a plurality of switches are connected to an arithmetic control unit (CPU) 11 and used to set each body information of the user.
[0033]
A plurality of body temperature measurement pads 5 provided on the upper surface of the mattress 1 constitute a body temperature measurement unit 12 that constitutes body temperature measurement means, and these body temperature measurement pads 5 include, for example, temperature sensing elements such as a thermistor inside. May be provided. This body temperature measuring unit 12 is connected to the CPU 11 and measures the body temperature of the user.
[0034]
Since the body temperature measuring pad 5 is configured to come into contact with the user's back and shoulders, the actually measured temperature is the body surface temperature of the user. In the present invention, the body surface temperature is described as the body temperature. To do. In actuality, the user may have a situation in which the body surface and the body temperature measurement pad 5 do not come into contact with each other during sleep, but by hanging the comforter, the temperature in the bed environment (the temperature between the comforter and the mattress) Assuming that the body surface temperature is approximately the same, this temperature in the bed environment is used.
[0035]
Similarly, the outside air temperature measurement unit 13 includes a temperature sensing element, and measures the temperature outside the bed environment (the room temperature in a sleeping state). It may be preferable to provide the outside air temperature measurement unit 13 in a place where the temperature of the room where the bed environment exists can be measured more accurately than in the operation box 2. The display unit 6 as a display means displays the result of the physical condition of the determined user.
[0036]
The heating / cooling unit 16 constituting the temperature adjusting means provided inside the operation box 2 heats and cools the air in the air mat constituting the mattress 1 in this embodiment. The heating / cooling unit 16 may have the same configuration as a general air conditioner (air conditioner), and may have a structure in which air is heated by a heater and cooled by a compressor. Furthermore, the air pressure control unit 17 is for adjusting the air pressure in the air mat constituting the mattress 1. In the embodiment shown in FIG. 1, the air mat constituting the mattress 1 is composed of a large number of air blocks partitioned from each other. The air pressure control unit 17 can individually adjust the air pressure in each air block. The heating / cooling unit 16 and the air pressure control unit 17 are also connected to the CPU 11 and their operations are controlled.
[0037]
Further, the clock device 18 and the storage device 19 are also connected to the CPU 11, the clock device 18 measures the current time and a certain time, and the storage device 19 stores the measurement result and the reference value. It is.
[0038]
Next, the flow of operation of the sleep environment control device of the present invention having such a configuration will be described.
[0039]
FIG. 4 is a main flow diagram of the operation of the apparatus of the present invention. In the main flow shown in FIG. 4, when the power switch is turned on in step S1, it is checked in step S2 whether personal information is stored in the storage device 19, and if it is stored, that information is displayed. Displayed in part 6. If it is not stored, it is displayed that it is not stored. Here, when the setting switch of the input device 7 is pressed in step S3, the setting mode is set. In step S4 which is this setting mode, the user inputs height, age and sex using the input device 7 which is an input means. In addition, the user's previous menstrual start date is also entered. After entering the numerical value, press the setting switch to confirm the input numerical value. Therefore, every time menstruation occurs, the user sets the start date in the setting mode.
Thereafter, when the measurement switch is pressed in step S5, the initial measurement mode of step S6 is set. This initial measurement mode will be described later.
[0040]
If initial measurement is performed, it will progress to step S7 and will be in the physical condition determination mode which determines which time of the menstrual cycle the day is. The physical condition determination mode will also be described later.
[0041]
Here, in the physical condition determination in step S8, the control of the environment during sleep differs depending on whether the physical condition is good or bad. The determination in step 8 can be made based on the physical condition flag of the storage device 19. This is a change in physical condition that appears in the female menstrual cycle, and it is said that the current physical condition is relatively good from the end of menstruation to after ovulation. Since the physical condition is generally not excellent before or during menstruation, the environment is controlled so that the subject can recover from fatigue and rest.
[0042]
Therefore, if it is determined that the physical condition is poor, the metabolic control (fat combustion control) mode is set in step S9 (S9). If it is determined that the physical condition is good, the sleep environment control in step S10 is performed. It becomes a mode. Each of these modes will also be described later.
[0043]
Then, it becomes a measurement in a normal sleep state. In this measurement during sleep, the temperature measurement unit 12 always measures the body temperature of the user or the temperature in the bed environment, detects body vibrations by the pressure sensor 10, and calculates the above heart rate and respiration rate from the signal. However, these are not shown in the present flow as being performed separately from the main routine.
[0044]
Next, the wake-up determination mode of step S11 for determining whether the user wakes up (wakes up) is entered. Here, in step S12, it is determined from the wake-up flag in the storage device 19 whether the user has woken up. If not, the process returns to step S7 to determine the physical condition again. If it is determined that the user has woken up, the result of the overnight sleep measurement is calculated in step S13. As a calculation of this result, the amount of body fat considered to have burned in this sleep is calculated from the basal metabolic rate of the user calculated in the initial measurement, sleep time, body temperature data, and the like.
[0045]
The result calculated here, the current physical condition, and advice based on the physical condition are displayed on the display unit 6 in step S14. An example of advice according to the determined physical condition is shown in the table of FIG. In this advice display, if it is determined that the PMS has occurred in the physical condition determination mode or the pregnancy is possible, advice on the matter is also displayed. Thereafter, in step S15, the measurement result is stored in the storage device 19. Thereafter, the power of the apparatus is turned off and the process ends.
[0046]
Next, each mode will be described.
Initial measurement mode
FIG. 5 is a flowchart showing the flow of the initial measurement mode. In this initial measurement mode, first, the user's weight, bioelectrical impedance, and other body parameters are measured before sleep. In step S21, the weight is first measured. This weight measurement is performed by a pressure sensor 10 that senses the air pressure in the mattress 1. As described above, the air pressure in the user mattress 1 changes. The amount of change is detected by the pressure sensor 10 and converted from the average value of the signals obtained by the CPU 11 into a weight value.
[0047]
In step S22, bioelectrical impedance is measured. For this measurement, the electrodes 3A to 3D and 4A to 4D provided on the surface of the mattress 1 are used. The current supply electrodes 3 </ b> A to 3 </ b> D and the voltage measurement electrodes 4 </ b> A to 4 </ b> D are sequentially switched to measure the bioelectrical impedance of each part and whole body. Since this bioelectrical impedance measurement method is already known, it will not be described in detail.
[0048]
Next, in step S23, the body fat percentage of the user is calculated from the measured bioelectrical impedance value, the body weight, and the height, sex, and age input in the setting mode. Since the calculation of the body fat percentage is already known, the description is omitted.
[0049]
Next, in step S24, the user's body temperature is measured. The body temperature is measured by measuring the temperature of the body surface in contact with the body temperature measurement pad 5. This is the resting body temperature (see JP-A-6-315424).
Next, in step S <b> 25, the body vibration of the user is detected by the pressure sensor 10. The vibration of the user's body on the mattress 1 appears as a change in the air pressure in the mattress 1, and the change in the air pressure is captured as a change in the pressure signal from the pressure sensor 10. Therefore, in order to obtain a heartbeat signal and a respiration signal of the user, sampling of the pressure signal from the pressure sensor 10 is performed at a sampling period of about several tens of milliseconds, and measurement is performed for about 30 seconds. The signal from the pressure sensor 10 obtained here is stored in the storage device 19.
[0050]
Next, in step S26, the heart rate and respiration rate of the user are calculated from the body vibration signal represented by the pressure signal from the pressure sensor 10 stored in the storage device 19 in step S25. From the signal from the pressure sensor 10, only a signal of several Hz to several tens Hz is extracted through a band-pass filter in the arithmetic control unit 11, and frequency analysis is further performed from the obtained signal. The heart rate is said to be about 80 beats per minute for a general adult, and the respiration rate is said to be about 15 times per minute. Thus, since the frequency (cycle) differs between heartbeat and respiration, it is possible to calculate by separating (vibrating) human body vibration signals. Let the heart rate and respiratory rate obtained here be the resting heart rate and the resting respiratory rate, respectively.
[0051]
Next, in step S27, the basal metabolic rate of the user is calculated. Here, the calculation of the basal metabolic rate is as follows.
[0052]
First, the user's muscle mass is calculated from the measured bioelectrical impedance value (BIA).
Muscle mass = a₁Height + b₁Weight + c₁BIA + d₁Age + e₁sex
Furthermore, basal metabolism is calculated.
Basal metabolic rate = a₂Muscle mass + b₂Resting body temperature + c₂Resting pulse rate + d₂Resting respiratory rate
(Where a₁, A₂, B₁, B₂, C₁, C₂, D₁, D₂, E₁Is a coefficient)
This calculation may be performed by using the reciprocal of age for the above-described lean mass in the calculation.
[0053]
Here, the value measured in this mode and each value calculated by the calculation are stored in the storage device 19 in step S28.
[0054]
This completes the initial measurement mode.
Physical condition judgment mode
FIG. 6 is a flowchart showing the flow of the physical condition determination mode. In this physical condition determination mode, the current physical condition (physical condition) is determined. In step S31, data such as the bioelectric impedance value and the weight measured in the initial measurement mode are read from the storage device 19, and the physical condition is determined in step S32.
[0055]
The measured BI is corrected based on the following correction equation.
[0056]
Correction formula 1: Weight correction BI = BI + A × difference from the weight measured first time
Correction formula 2: Weight correction BI = BI + B × difference from previously measured weight
That is, the weight correction BI is obtained by subtracting or adding the increase / decrease in BI accompanying the increase / decrease in weight from the BI, and is calculated from the correction formula 1 or the correction formula 2. Here, A and B are correction coefficients. Thereby, the weight correction BI from which the influence of the weight change is removed is calculated.
[0057]
Data such as the corrected BI value for several days from the storage device 19 and the physical condition of the previous day, the menstrual start date, etc. are read into the CPU 11. Further, in the CPU 11, based on the relationship between the BI and the physical condition appearing in the woman's monthly period as described above, the weight correction BI measured this time and the weight correction measured for several days until the previous day read from the storage device 19. Based on the physical condition of the BI and the previous day, menstruation start date data, etc., the person to be judged is currently in a physical condition period. In other words, the physical condition of the first period (menstrual period), the second period (good period), the third period (maintenance period), the fourth period (malfunction period), and the fifth period (fertile period) Determined.
[0058]
Here, physical condition determination will be described. However, this determination example is for a person whose menstrual cycle is a 28-day cycle, and the menstrual cycle varies from person to person, so the number of days in each period is appropriately changed according to the cycle of the user.
[0059]
FIG. 11 is a diagram illustrating a method for determining each period from the BI value. In this case, the first period (menstrual period) is about 7 ± a days from the start date of menstruation, and the second period (good period) from the next day to the day when the BI value changes from high to low. The third period (maintenance period) is approximately 7 ± b days from the day when the BI value changes to a low value, and the fourth period (abnormal period) is from the next day to the next menstrual start date. . Furthermore, the third period before and after the BI changes from a high value to a low value is defined as a fifth period (fertile pregnancy period). As a determination criterion for the change in the BI value, it is assumed that the low BI value changes from the high BI period to the low BI period when a low BI value of 4% or more of the average BI value in the past high BI period occurs.
[0060]
Further, in the fourth period (strange period), if a low BI value of 1% or more occurs compared to the past average BI value during that period, it is assumed that swelling has occurred. The swelling level is 1, and the swelling level is 2 at a low BI value of 2% or more, and the swelling level is 3 at a low BI value of 3% or more.
[0061]
In the case of the measurement subject in FIG. 11, the average value of the high BI value period is about 590Ω, and the average value of the low BI value period is about 560Ω. Accordingly, it is assumed that the low BI value period has been reached when the BI value of 566.4Ω or less, which is 43.6% of 590Ω, is 23.6Ω lower. Since the low BI value appeared on the 15th day, the three days before and after this day are the fertile period.
[0062]
In addition, the average BI value in the fourth period is 560Ω, and the 1% lower BI value is 554.4Ω or less and the swelling level is 1, and the 2% lower BI value is 544.8Ω or less and the swelling level is 2 and 3%. When the low BI value is 543.2Ω or less, the swelling level is 3.
[0063]
Therefore, in the sleep environment control device for women of the present invention, each period appearing in a female monthly cycle is determined as follows.
[0064]
The date of the menstruation start date data is set as the menstruation start date.
[0065]
One week ± a from the start date of menstruation is the first period (menstrual period).
[0066]
The period from the next day to the previous day when the BI value 4% lower than the average BI value of the second period in the past is measured as the second period (good period).
[0067]
The third period (maintenance period) is from the next day to the day one week before the next menstrual scheduled start date estimated from past data.
[0068]
The period from the next day to the day when the next menstrual start date data is input is defined as a fourth period (abnormal period).
[0069]
Further, based on the past data, the average number of days from the next expected menstrual start date to the ovulation date is obtained, and the third period before and after the estimated ovulation date is set as the fifth period (fertile pregnancy period). Here, the estimated ovulation date is 14 days before the expected menstrual start date. However, this fifth period (fertile pregnancy period) is corrected when the change in the measured BI value from the high price period to the low price period is determined. That is, when ovulation is determined by the change in the BI value earlier than the estimated ovulation date, three days from that date are set as the fifth period (fertile pregnancy period). Conversely, if the BI value does not change even after the estimated ovulation date has passed, the fifth period (fertile pregnancy period) will be continued during that period until 3 days after ovulation is determined due to the change in the BI value. Is the fifth period (the pregnancy possible period).
[0070]
Based on the determination method as described above, it is determined whether the measured person is currently the same as the period up to the previous day or has changed to the next period. Note that this physical condition determination can be performed when past measurement BI values for one cycle are prepared, and is not determined until the data is prepared. Alternatively, the number of days may be calculated from the number of days in the menstrual cycle input by the user to make a simple determination. In such a case, a message “content is insufficient” is displayed on the display unit 6 and the sleep environment is not controlled. In this case, the display unit 6 operates as a notification unit.
[0071]
In step S33, it is each period determined in this way, and it is determined which period currently corresponds. The second period and the third period are in good physical condition. In the fourth period, the physical condition is poor.
[0072]
If the physical condition is good, the physical condition flag of the storage device 19 is turned on in step S34. On the other hand, if the physical condition is poor, in step S35, the sleep environment is controlled so as to rest.
[0073]
Thus, the physical condition determination mode ends.
Basal metabolic control mode
FIG. 7 is a flowchart showing the flow of the basal metabolism control mode. In this basal metabolism control mode, the air temperature in the air mat 1 is controlled based on the result in the physical condition determination mode. If there is a temperature difference between the body temperature and the environment temperature, metabolism occurs due to a body function called homeostasis that tries to keep the body temperature constant, but if the environment temperature is slightly higher than the body temperature, the reverse Attempts to maintain body temperature by lowering metabolism. When it gets hotter, metabolism for sweating occurs, but during sleep, sweating increases the humidity in the bed and induces sleepiness.
[0074]
Therefore, when the physical condition is good, the temperature in the mattress 1 is lowered, thereby lowering the environmental temperature surrounding the user and the temperature in the bed environment. As a result, the metabolic rate of the user is increased and the body fat is easily burned.
[0075]
First, in step S41, the current user's metabolic rate data calculated by the initial measurement is read from the storage device 19. In step S42, the amount of fat burning required during sleep is calculated from the user's metabolism calculated by the read initial measurement and the appropriate body fat mass data stored in the storage device. The appropriate body fat mass data is the ideal body fat mass at the same name and age as the user.
[0076]
Here, based on the calculated fat burning amount, conditions for increasing the metabolic rate are determined. First, in step S43, the outside air temperature measurement unit 13 is used to measure the outside air temperature (the temperature in the room where the user is present). Further, in step S44, the body temperature of the current user and the temperature in the bed environment are measured again in the body temperature measuring unit 12. In step S45, the temperature difference between the measured outside air temperature and body temperature is obtained, and this value is 5 In step S46, the temperature is controlled to be lower than the temperature of 10 ° C. or more. If it is within 5 ° C., the temperature in the bed environment is lowered in order to lower the environment surrounding the user. That is, the air in the air mat 1 is cooled in the heating / cooling unit 16 in step S47. On the other hand, if the temperature is already 5 ° C. or higher, it is assumed that the temperature is sufficiently lowered, and temperature adjustment (cooling) is stopped in step S48.
[0077]
For example, when the outside air temperature is 20 ° C. and the body temperature (body surface temperature) is 18 ° C., the air in the air mat 1 is heated by the heating / cooling unit 16 so that the temperature difference with respect to the body temperature is 5 ° C. or more and less than 10 ° C. Cool down. Therefore, when the temperature difference is confirmed again in this mode, the cooling is performed until a temperature difference of 5 ° C. or more is detected, and the cooling is stopped when the temperature difference becomes 5 ° C. or more. This temperature difference is not limited, but if a high temperature difference continues with heating or cooling, the user gets up and cannot sleep due to the temperature difference, so the user may continue to sleep. The temperature is adjusted as much as possible.
[0078]
As described above, in the basal metabolism control mode, the accumulation of body fat is prevented by consuming energy that cannot be consumed during sleep when the physical condition accompanying the user's menstrual cycle is good.
Sleep environment control mode
FIG. 8 is a flowchart showing the flow of the sleep environment control mode. In this sleep environment control mode, body fatigue is recovered by controlling the environment so that the user can sleep well. As described above, if there is a difference between the user's body temperature and the temperature in the bed environment, metabolism occurs in the body. Therefore, here, the measured body temperature and the temperature in the bed environment are controlled to be approximately the same, that is, the temperature difference is ± 1 to 2 ° C. with respect to the body temperature. As a result, the metabolic rate is reduced, and an environment where the patient can sleep well is established.
[0079]
First, in step S61, the current user's body temperature is measured again. Based on this temperature, the arithmetic control unit 11 controls the heating / cooling unit 16 in step S62 to adjust the temperature of the air in the mattress. To do.
[0080]
This is the end of the sleep environment control mode.
Wake-up judgment mode
FIG. 9 is a flowchart showing the flow of the wake-up determination mode. In this wake-up determination mode, it is determined whether the user has changed from a sleep state to an awake state (awakened state).
[0081]
When the human body transitions from the sleep state to the awake state, the heart rate of the human body increases. Therefore, it is determined whether the user has become awake by capturing this physical change.
[0082]
In step S81, the heart rate data and the reference heart rate detected in another routine not described in the main routine and stored in the storage device 19 are read. Here, the reference heart rate is an average value of the heart rate during the sleep time of the user.
[0083]
In step S82, the reference heart rate is compared with the current heart rate, and in step S83, it is determined whether the difference is within a certain range. Here, it is determined whether it is within 20% of the reference heart rate. If it has exceeded, it is assumed in step S84 that the state has shifted to the awake state, the wake-up flag is turned on, and if it is within that range, it is assumed in step S85 that it is still sleeping.
[0084]
This completes the wake-up determination mode.

[0086]
In the above-described embodiment, the bioelectrical impedance and body weight of the subject lying in the lying position are measured before sleeping, and the physical condition appearing in the woman's monthly cycle is determined from the variation in the value obtained by correcting the bioelectrical impedance value with the body weight. However, the present invention is not limited to this, and the configuration may be determined by a general basal body temperature method.
[0087]
Or it is good also as a structure which measures the body temperature and bioelectrical impedance during sleep, and determines the physical condition which appears in a woman's monthly cycle from the change of both.
[0088]
In addition, as a device for obtaining a menstrual cycle from a general number of days calculation, a device for determining the current physical condition based on input data related to a menstrual start date may be used.
[0089]
In this embodiment, the initial measurement is performed before sleep, and the menstrual cycle of the woman and the current physical condition are determined from the measured values. However, if the initial measurement is performed after waking up, the body is Therefore, it is considered that more accurate physical condition determination can be performed while suppressing fluctuations in body temperature and bioelectrical impedance.
[0090]
In this embodiment, the body temperature measurement pad and the bioelectrical impedance measurement electrode are provided on the mattress.For example, the measurement is performed under the tongue using a general basal thermometer, and the data is input. Alternatively, a basic thermometer, a bioelectrical impedance meter that can measure impedance between both hands, both feet, or the whole body is connected to the sleep environment control device, and the data measured with these instruments is taken in and the calculation and determination can be performed. Good.
[0091]
Alternatively, body temperature is known to change during the day according to circadian rhythm. Therefore, instead of measuring body temperature at a certain time every day, for example, if you carry a small terminal that can measure body temperature and continuously measure body temperature, you can grasp the fluctuation rhythm of body temperature This makes it possible to estimate the basal body temperature more accurately, so that the physical condition can be determined with high accuracy.
[0092]
In the above-described embodiment, the main routine is shown to perform each mode at the same level (frequency) in the normal measurement state. However, the basal metabolic control mode and the sleep environment control mode are frequently performed. Since it is not necessary, better control is possible if the mode is changed every 5 to 10 minutes.
[0093]
Moreover, as control of sleep environment, it is good also as what adjusts sleep environment, such as the temperature in a bed environment, a sound, and a smell.
[0094]
In addition, in the basal metabolism control mode and the sleep environment control mode, the temperature and the like may be controlled by obtaining the amount of fat burning during sleep in real time using, for example, the following equation.
[0095]
Fat burning amount = a metabolism amount + b body fat amount + c (body temperature / outside temperature) + d heart rate change + e respiratory rate change
In the basal metabolic rate control mode, the optimum temperature control pattern may be determined from both the fat burning amount and the temperature adjustment, and the temperature control suitable for the individual may be performed. The same applies to the sleep environment control mode.
[0096]
  Further, in the above-described embodiment, as a means for configuring the bed environment, the user is lying down.DoAn air mat is used as a mattress, and the temperature inside the bed is controlled by heating or cooling the air (air) enclosed in the air mat. It may be a water mat that warms or cools. Moreover, it is not limited to water but can be implemented as long as it is liquid, and does not limit the substance to be sealed.
