The metabolic rate increasing room is constituted of a heat insulating coating material which is firmly coated over the interior surface of a room, which is selected from one or more of a wall, a ceiling and a floor of the room. The interior material for the metabolic rate increasing room is a heat insulating coating material which is firmly coated onto the surface of the building interior material, and the building interior material is attached to a building frame after completing frame construction of the building so as to face to the inside of room.

Description

  The present invention relates to a room equipped with an interior material that improves and enhances a person's metabolic rate, and the metabolic rate is improved even if a person does not perform a special exercise or is only living normally. The present invention relates to a metabolic rate improving room that, when exercising in this room, exhibits a metabolic rate improving effect prominently, and provides a diet effect and other favorable effects on the body by improving the metabolic rate.

  As an invention for promoting metabolism indoors, the technique of Patent Document 1 is disclosed. The invention of Patent Document 1 uses ore powder that emits a large amount of far-infrared rays, which is known to promote blood circulation and enhance the body's qi, and performs farting by absorbing far-infrared rays from the entire body. It is a room structure that is suitable for a poultry room and can be attached to the bottom of the wall of the room, which can discharge waste products inside the body, promote the metabolism of the human body, and eliminate stress and fatigue. A heat insulating material such as styrofoam 2 and a heat insulating material 3 are laminated in order from the bottom on the inner bottom surface of the body 1, and ore powder 4 from which far-infrared rays diverge on the upper surface so as to have the same height as the frame body 1. Velcro fasteners 7, 7 ′ in which the thermal tubes are embedded in the ore powder 4 layers at appropriate intervals, the lid 6 is attached to the upper surface of the ore powder 4 layer, and the bottom surface of the edge and the upper surface of the frame 1 are attached. Far red that will be detachably attached via A room structure for diverging lines.

  However, in Patent Document 1, the ore powder 4 that emits far-infrared rays is laminated under the floor, and a heat pipe is arranged inside the ore powder 4 layer to supply heat, so installation and enforcement are complicated and introduced. The cost was high and the running cost was high.

On the other hand, when a lightly dressed person is active in a mid-temperature room where neither hot nor cold feels, the energy that the human body radiates toward the surrounding wall is much higher than the amount of incident light on the human body. It is the main cooling means. The radiant heat balance of a person spending in the room is obtained by multiplying the average skin temperature and the average radiant temperature of the human wall by the respective emissivities (skin: 0.98, wall: 0.90-0.95). The radiant heat transfer coefficient (4.0 kcal / m ² / h / ° C.) is used in a general room. Attempts to use radiant heat have been tested, like radiant air conditioning that consumes external energy, such as electricity, to regulate the temperature of the ceiling of a hospital room, while manipulating the emissivity of interior materials. Thus, there is no known attempt to verify the effect of affecting human temperature regulation without consuming external energy.

  Therefore, an object of the present invention is to provide a metabolic rate improving room based on an interior material that is easy to install, has low initial costs, and does not require running costs.

In the present invention, the occupant's body temperature and metabolic response when artificially increasing the emissivity of the inner wall surface of the room with an interior material such as wallpaper have been observed to arrive at the present invention.
In order to solve the above problems, the present invention is specifically configured as follows.

(7)
A room for improving metabolic rate that enhances metabolic activity in the organism,
A room for improving metabolic rate, characterized in that a heat insulating ceramic is arranged on one or more indoor surfaces selected from an indoor wall, ceiling, or floor.

  Since this invention is the said structure, the following effects are exhibited. The metabolic rate of the living body can be improved simply by disposing a heat insulating ceramic on the inner surface of the room. The inner surface on the indoor side of the room is a wall, a ceiling, or a floor, and is an interior material surface that is affixed thereto, or a surface of a base of the wall, ceiling, or floor. In the case of an existing room, a heat insulating ceramic may be fixed on the interior material. In the case of a new construction, an interior material to which a heat insulating ceramic is fixed in advance may be attached. Furthermore, a heat insulating ceramic may be fixed on the lower side. Therefore, it is possible to provide a metabolic rate improving room that is easy to install, has low initial costs, and does not require running costs. As a result, there is a multifaceted health promotion effect on the living body based on the improvement of the metabolic rate without performing special exercise, that is, in a normal life. For example, a diet effect, a sleep can be illustrated. As the arrangement of the heat insulating ceramic, a ceramic block, a ceramic plate or a ceramic outer wall panel is arranged on the inner surface of the indoor side, and is adhered to the surface of the interior material. Or the method of coating can be illustrated. If it is a ceramic coating material, the existing room can be renovated to a metabolic rate improving room simply by applying it to the surface of the existing interior material. If a thermal insulation ceramic material is placed on the surface of the existing interior material in advance, even in new buildings, the room can be made into a room with improved metabolic rate, which can be changed to a room with improved metabolic rate, making it extremely simple and economical. It is.

The fact that the average skin temperature of the subject who entered the vinyl chamber in FIG. 2 is higher than the value in the ceramic coating material chamber is a factor that increases the amount of radiation heat radiation.

[Introduction]
When the body temperature of a thermostat is kept constant, it means that all the heat generated in the body is released outside the body. There are three ways of heat flowing out of the body: conduction, convection, and radiation. By adjusting these ratios according to environmental conditions, the total heat release becomes equal to the calorific value. Such adjustments are made.

  Conduction means that the body directly contacts the material and releases (in) heat. Convection is the transfer of heat or water vapor to the air around the body and release it on the flow. Radiation is the energy of electromagnetic waves emitted by all objects of absolute zero or higher according to their temperature, and heat exchange is performed between all opposing object surfaces and the body surface according to the temperature difference and emissivity. Yes. The emissivity is a numerical value indicating how much the black body is attenuated according to the surface properties when the maximum value is 1.0, and that of human skin is about 0.98.

  An environment in which a person who is sitting in a chair with a T-shirt and half pants + briefs feels thermally comfortable is all the heat generated in the body (resting metabolism = 1500 to 2000 kcal / day). In this case, the heat dissipation mechanism is convection and radiation, but at that time humans can hardly realize that heat is radiated by convection and radiation.

  In the case of indoors, since it is within the range of natural convection with almost no airflow (= wind speed), it is considered that convective heat radiation takes the minimum value. Therefore, it can be considered that the main part of the metabolic energy at rest in the room at 28 ° C. set in the experiment is released outside the body by radiation. Radiation heat dissipation means that invisible electromagnetic waves (far infrared rays) are emitted from each other, and the substantial heat flow at that time depends on the temperature difference between the two surfaces and the emissivity.

  The inventors have conducted a simple experiment using a human body radiant thermometer (Patent No. 4608653), and in the radiant heat exchange between the heat generating body and the heat insulating coating surface similar to the human body, the surface temperature of the heat generating portion of the radiant thermometer. It has been found that the amount of heat radiation increases as the temperature rises. The difference in the radiant heat exchange between the wallpaper coated with the ceramic coating material and the vinyl-based wallpaper, which was clarified in this experiment, is that the ceramic coating is on the low temperature side with the surface temperature of the human body radiation thermometer being 23.46 ° C. The heat radiation toward the wallpaper coated with the material is larger than the heat radiation to the vinyl-based wallpaper, and conversely, the heat radiation amount decreases on the high temperature side.

  In another test result, the skin temperature and rectal temperature of the subject at rest and light exercise were measured, and peripheral skin was observed during light exercise in a small room equipped with an interior material coated with a ceramic coating. It was confirmed that the temperature, average body temperature and rectal temperature were significantly higher than when the same was spent in a room decorated with vinyl-based wallpaper. The possibility of increase was suggested.

  Based on these findings, in order to clarify the cause of the body temperature difference caused by the difference in the interior material, direct proof of the metabolic enhancement effect during exercise using a method of collecting exhalation and directly reading the metabolic calorific value, did.

[Test method, summary of results]
Two hot carpets are each provided with a wooden frame of 2m on one side, one inner wall is coated with white ceramic coating wallpaper (Room1), and the other is decorated with a plasterboard with a commercial white vinyl coated wallpaper (Room2). A 30 cm gap was provided in each of the four directions for entry and exit of the subject and ventilation, and a cloth chair and a bicycle ergometer were installed in the room (FIG. 9). The entire laboratory in which Room 1 and Room 2 were installed was heated at 28 ° C. as a guide and stirred with a fan.

  In addition, the hot carpet power supply was automatically turned ON / OFF so that the floor surface temperature was the same as the other wall surfaces. All eight subjects were long-distance runners, dressed in short-sleeved T-shirts and half-pans + briefs, and allowed 30 minutes of bicycle rowing exercises after resting for 2 hours in the test room.

  During this time, the skin temperature 7 points and rectal temperature were measured continuously, exhaled air was collected, and the metabolic rate was calculated for each breath from the oxygen consumption. Each subject formed a pair of two people and experienced both of them once each day on different days. At that time, a blind test was conducted in which the subject was not informed about the material of the interior material.

[Results and discussion]
There were no differences in the room temperature, humidity, airflow, and inner wall surface temperature of Room 1 and Room 2. There were no differences in the skin temperature, rectal temperature, and metabolic rate of the subjects at rest. However, the results showed that the metabolic rate during exercise, rectal temperature and heart rate were significantly higher in Room 1, and skin temperature was significantly lower.

  There is no difference between Room1 and Room2 other than the material of the wallpaper. Therefore, it can be considered that the causes of the difference in these test results are all attributed to the material of the wallpaper.

  The heat source in the room comes from the subject and is considered to be re-radiating or reflecting immediately upon receipt of the surface of the wallpaper. Although humans are unaware of such faint radiant heat, sympathetic nerves that regulate heart rate and metabolism appear to respond sensitively.

  It is not easy to rationally explain that the response to sympathetic stimulation of heart rate and metabolic rate is prominent under conditions that should be parasympathetic dominant, such as exercise, but the results In particular, Room 1 with a wallpaper coated with a ceramic coating material improved the metabolic rate. In another experiment where all subjects were replaced, the same results were observed that the ceramic coating wallpaper increased skin temperature and rectal temperature during exercise, and it was also confirmed that the metabolic rate was increased.

  Hereinafter, more specific test methods, measurement results, and considerations will be described.

[experimental method]
The subjects were eight active long-distance runners who belong to the track and field department of the university and are engaged in competition activities (Table 1). Table 1 shows the body measurement data of the subject on the day of the experiment.

  The experimental apparatus (room) is as described above. Since the floor temperature tended to be lower than the wall surface, a hot carpet was inserted under the apparatus, and the thermocouple attached to the floor was adjusted to the set temperature of the room temperature so that the inner wall surfaces of the apparatus were all the same.

  During the experiment, the air conditioner in the laboratory was set to 28 ° C. from the previous day and continued to operate so that the dedicated device and the laboratory were in sufficient thermal equilibrium. In each room, one PMV environmental measurement recording logger, bicycle ergometer and deck chair were installed. Eight subjects who are doing sports with good health made a pair with the same partner every time, and went to the experiment.

  On the day of the experiment, they were gathered at 8:30 pm and dressed in an experimental garment, and then a rectal temperature measuring probe with a transmitter (Type HT150002, HQ Inc., USA) was inserted into the ultrathin rubber sonde and inserted through the anus. Next, a thermistor thermometer for skin temperature measurement was attached to each site shown below, measured at 1-minute intervals, and recorded in a portable data logger. The recorded data was downloaded to a computer and collected after the experiment was completed using dedicated data exchange software.

  In this state, after sitting in the chair outside the room, the two persons were moved into the room at the same time to spend 2 hours in the chair. In addition, a 30-minute bicycle rowing exercise was then performed, followed by a 30-minute rest on the chair.

During this period, the rectal temperature was kept for 10 minutes, the skin temperature was kept for 1 minute, and the body weight measurement with an accuracy of 10 g was measured and recorded in accordance with the change of each way of spending. The amount of heat converted from infrared rays and flowing through the boundary surface on a black body plane at 35 ° C. simulating human skin temperature was expressed in W / m ² / h. In addition, average body temperature, average skin temperature, and heat storage amount were calculated by the following equations.

Average body temperature (° C) = rectal temperature x 0.8 + average skin temperature x 0.2
Average skin temperature (° C) = Forehead temperature x 0.1 + Chest temperature x 0.25 + Forearm outer temperature x 0.07 + Upper arm central outer temperature x 0.13 + Thigh central outer temperature x 0.25 + Lower thigh central outer temperature x 0.15 + Upper surface temperature of foot sole x 0.05
Heat storage (kcal) = 0.82 (specific heat of human body) × average body temperature (° C.) × body weight (kg)

  Meal conditions were strictly adjusted, and everyone was allowed to consume the same meal content and amount 2 hours before the start of the experiment. The measurement items are as shown in each figure.

[Data collection]
Environmental measurement record: Two PMV loggers (JMS, Tokyo) were placed in each room, and the sensors were placed so that the height of the sensor was the height of the chest of the chair. The measurement recording interval was 5 minutes. Room temperature, humidity and airflow were measured and recorded. The room temperature setting of the packaged air conditioner in the entire laboratory was 28 ° C. The measurement interval of skin temperature at the forehead, right chest, outer upper arm, outer forearm, outer thigh, outer lower leg and back of the foot was 2 minutes, and rectal temperature was 10 minutes. The exhaled breath was collected for 5 minutes at 30 minute intervals, the oxygen concentration for each breath was measured, and the metabolic calorific value was calculated from the difference from inspiration. For skin temperature, the average skin temperature was determined from the proportion of the measured area, and the volume ratio of the volume to the rectal temperature was determined to determine the average body temperature. The skin temperature, rectal temperature, average skin temperature, average body temperature and metabolic rate at each site were arranged in chronological order, and their respective trends were observed.

[Homogeneity of laboratory measurements]
Since rooms with the same specifications with different interior materials are installed, it is necessary to prove that the environmental conditions of both rooms are the same except for the interior materials. Therefore, Table 2 shows the measured values of the environmental conditions in both chambers during the experiment. About 100 sets of measurements are recorded for each of the eight measurements. If the difference between these average values is tested, there may be a significant difference, but the substantial difference is that the room temperature is ± 0.2 ° C, the humidity is ± 2%, and the airflow is within -0.01 m / sec. It is the range that can be declared that both rooms are under the same environmental conditions.

[Equivalence of interior material surface temperature]
The surface temperature of the interior material was measured by taking a picture with a thermo camera and reading each location of the image.

[Metabolism when resting on a chair and exercising on a bicycle]
When the chair was resting, there was no difference in the amount of metabolism due to the difference in the interior materials. On the other hand, immediately after the start of exercise, the ceramic coating interior showed significantly higher metabolic rate than the vinyl cloth interior. The increase rate was about 15%.

  In the metabolic rate calculated by dividing the metabolic rate by the body surface area, this difference was 10% (FIG. 1). Of course, the load settings of the two bicycle ergometers used in the experiment are the same, and even if there is a slight difference in equipment between the bicycle ergometers, the difference is in a range that the subject cannot recognize.

[Skin temperature when chair is resting and cycling]
The skin is a place where heat energy is converted into infrared rays and vice versa, and its temperature is a decisive factor for the amount of energy released (entered). The average skin temperature can be calculated by a method of measuring the skin temperature of 7 parts of the body and averaging this according to the proportion of the area of each part.

  The values obtained in this manner are not different between the groups at rest, but the vinyl group continues to rise for a long time during exercise, whereas the ceramic coating interior group stops rising in a short time. The difference between the two groups after the minute became statistically significant (arrow in FIG. 2). The skin temperature of the upper arm, forearm, and thigh changed similarly to the average skin temperature.

  The skin temperature at the center of the forehead of the ceramic coating material interior group remained consistently higher than that of the vinyl group throughout both resting and exercise conditions (FIG. 3). The skin temperature of the chest was similar to that of the forehead (data not shown).

  Skin temperature at the lower leg and back of the foot is not different between groups throughout the course of the experiment. There is no statistically significant difference in the skin temperature on the soles of the feet due to the large variation in the numerical value of the ceramic coating interior group, but other skin temperatures such as the ceramic coating group exceeding the vinyl group after the start of exercise A peculiar phenomenon not observed in the average skin temperature was observed (arrow in FIG. 4).

[Rectal temperature when sitting on a chair and exercising on a bicycle]
The rectal temperature at rest remained high in the ceramic coating interior group, but there was no difference until 2 hours later. During the last 10 minutes of rest, the ceramic coating interior group clearly showed a high value (P <0.05). After the start of exercise, the value of the ceramic coating material interior group clearly showed a high value immediately after, and the difference gradually increased from 0.20 ° C. to 0.27 ° C. (FIG. 5).

[Body heat balance when sitting on a chair and cycling]
The metabolic calorific value when sitting in a chair and staying calm without changing body temperature should be equal to the sum of heat released by conduction, convection and radiation. Metabolic calorific value can be obtained by measuring oxygen consumption in exhaled breath. The amount of heat released by conduction is negligible for a chair.

The amount of heat released by convection is the convective heat transfer coefficient published for each posture and work content (when the chair is at rest; 0.18 kcal / m ² / h / ° C., during bicycle exercise; 5.2 kcal / m ² / h / C.) can be easily calculated as a function of the temperature difference between the average skin temperature and room temperature.

  The heat deprived from the body when sweat evaporates can be calculated from the mass transfer rate, but with a precise scale, the most accurate method is to calculate from the amount of change in weight and the latent heat of vaporization of water. . The amount of heat released by radiation is the average skin temperature, wall temperature, and the respective emissivity (skin; 0.98, ceramic coating material; 0.95 (reflecting the measured value), vinyl; 0.90 (temporary value)) In the Stefan-Boltzmann equation.

[Metabolic calorific value]
The body temperature of constant temperature animals including humans is maintained at a constant level by releasing all the heat (metabolic calorific value) generated in the body. As shown in Table 3, the ceramic coating material interior group during exercise generated heat of 116 kcal / m ² / h, and the vinyl group generated 104 kcal / m ² / h. Therefore, in order to adapt to this and promote heat dissipation, the body is considered to increase the blood flow to the skin and raise the skin temperature. This background is expected because the skin temperature during the exercise of the ceramic coating material interior group rapidly increased in FIGS.

[Radiation heat dissipation]
The amount of radiant heat exchange between the surface of the human body and the wall surface during exercise can be obtained by the following equation (1) (Stepan-Boltzmann's law).

R = ε ₁ σT ₁ ⁴ −ε ₂ σT ₂ ⁴ (Kcal / m ² / h) (1)

Where R is the amount of radiant heat exchange, ε ₁ is the emissivity of human skin, ε ₂ is the emissivity of the wall surface, σ is Stefan-Boltzmann constant = 4.88 × 10 ⁻⁸ (kcal / m ² / h / K ^{− 4} ), T ₁ indicates the skin surface absolute temperature, and T ₂ indicates the wall surface absolute temperature.

Using Equation (1), the amount of radiant heat released by the subject in the ceramic coating material interior group whose average skin temperature is 0.5 ° C. lower toward the surrounding wall surface at 28 ° C. (42 kcal / m ² / h, wall surface 0.95 as the emissivity adopted (measured value)), and radiate heat subjects vinyl group to release (21kcal ^{/ m} 2 ^/ h, assuming estimated that emissivity 0.90) than 21kcal ^{/ m} 2 ^/ If it is as small as h, it can be estimated.

[Convection heat dissipation]
The convection heat dissipation amount (C) in still air is expressed by the following equation (2) using the convective heat transfer coefficient (h _c , kcal / m ² / h / ° C.) experimentally obtained for each posture and work content. It can be calculated by The sitting position h _c is 1.8 and during cycling is given 5.2.

C = h _c (Ts−Ta) (kcal / m ² / h) (2)

However, C is the convective heat release, h _c is the convective heat transfer coefficient, Ts is the average skin temperature, and Ta is the room temperature.

Convection heat dissipation when resting on the chair: Equation (2) and average skin temperature: ceramic coating interior; 10.3, vinyl interior; 10.8 (kcal / m ² / h) Convective heat release: Ceramic coating material interior; 31.2, vinyl interior; 35.9 (kcal / m ² / h), respectively. The results are summarized in Table 3.

[Heat release due to sweating (including insensitive digestion)]
The amount of sweating (g / m ² / h) is obtained by measuring the amount of change in body weight with an accuracy of 10 g and dividing by the body surface area. The values at rest were as follows: ceramic coating material interior: 25.1, vinyl interior: 26.6, during exercise, ceramic coating material interior: 100.2, vinyl interior: 87.8 g / m ² / h. The evaporation heat release (kcal / m ² / h) due to perspiration and insensitive vaporization was determined with the latent heat of vaporization near the skin temperature being 580 cal / g, and is shown in Table 3.

[Heat storage amount]
The amount of stored heat is a number representing the total amount of heat energy held by the body, and is given by the product of average body temperature (° C.), specific heat of the body (0.83), and body weight (kg). The display unit is kcal. The average body temperature used here is given as the sum of 30% and 70% of the average skin temperature and rectal temperature, respectively.

  The amount of heat storage during rest and exercise is clearly larger in the ceramic coating interior group than in the vinyl interior group (comparison between the left bar and the right bar in Fig. 7). No obvious increase was observed (comparison between left bars and right bars).

  The results of these comparisons show that the body temperature is adjusted appropriately in a room temperature of 28 ° C., with a healthy human being, and with an increase in exercise load enough to change from sitting on a chair to a light bicycle. It shows that it can be predicted that an extreme increase in heat storage will not occur due to the increase in emissivity.

[Heart rate when sitting on a chair and cycling]
Heart rate per minute is a good indicator of sympathetic tone. In general, for thermal stimulation, when feeling cold or cold, more sympathetic nerve signals are generated and the peripheral blood vessels are contracted to lower the skin temperature, thereby suppressing heat dissipation and body temperature. It is thought that adjustments are made so as not to lower the value. FIG. 8 shows the heart rate during the experiment divided into a ceramic coating material interior group and a vinyl interior group.

  There is no statistical difference between the groups in the heart rate at rest, but during exercise, the ceramic coating interior group shows a significantly larger value than the vinyl interior group. The difference in the heart rate of the same group spent in a place where there is no difference in environmental factors other than the interior materials of the room means that sympathetic nerves are the only cause of the difference in interior (difference in surface emissivity). It shows that tension is occurring.

  Among the measured indices, the decrease in average skin temperature and other skin temperature, the increase in metabolic rate, the increase in rectal temperature, and the increase in the amount of stored heat when ceramic coating is applied are all explained consistently by the increase in sympathetic nerve tension. it can.

  It is necessary to further consider the reason why such a significant difference is not observed at rest, but becomes significant only during exercise. However, although there is no statistical difference between the resting data, the skin temperature, rectal temperature, heart rate metabolic rate, etc. show sympathetic nervous tension, and there is variation in resting data. It can be interpreted that it is only hidden in

[Summary and conclusion of results]
It can be easily obtained by numerical simulation by a computer how the slight difference in the emissivity of the room wall will affect the people staying in the room. However, there is no example that has been experimentally verified for human subjects.

  By using a ceramic particle-containing coating material having a large emissivity called a ceramic coating material in the interior of a room, it has become possible to verify this experimentally.

  When staying in a room with ceramic particle-containing coating (made by Nisshin Sangyo Co., Ltd., heat-insulating coating), the metabolic rate increases by about 10% and the skin temperature is low (average skin temperature is 0.5 ° C). As a result, the rectal temperature was increased by 0.3 ° C., and the heart rate increased by up to 5 beats per minute. This phenomenon was particularly noticeable during exercise. These results are close to physiological phenomena that occur when the sympathetic nerve is in tension.

  The only difference between the two experimental devices is the interior material. It was shown that the interior material of ceramic coating material has the effect of stimulating the sympathetic nervous system. A direct measurement of the metabolic rate shows an increase of 10%, and it is considered that the high emissivity of the interior material has a strong sympathetic nerve activation inducing action (FIG. 10). The sympathetic nervous system can be easily put into a transient tension state by touching cold air or a cold object. It is considered that the ceramic coating material has an action to make it.

  From the above test results, by using a heat insulating coating material on the surface of indoor interior materials, the metabolic rate is improved for living bodies such as humans and other animals, and the accompanying health promotion effect, for example, a diet effect is obtained. Can be realized.
