I. Is floor heating bad for the body?
Geothermal is actually laying heat media evenly in the floor, such as hot water pipes, cables, etc., using the principle of heat radiation to achieve the purpose of heating.
All objects in nature emit thermal radiation to space, and at the same time continuously absorb thermal radiation emitted by other objects, so that there is heat transfer between objects. It can be seen that thermal radiation is only a way of heat transfer, and sunlight is also transmitted to the earth through thermal radiation, so it will not cause harm to the human body.
Second, will electric floor heating cause harm?
In addition to the energy transferred by thermal radiation, electric floor heating also has energy generated by electric and magnetic fields, but the impact of this energy on the human body is equivalent to that of pickles and coffee. Because the electric heating used by electric floor heating is a low-frequency current, it will not cause harm to the human body. What’s more, there will be casings, floors or tiles on the cables, and with these shielding, the magnetic and electric fields of the cables will be further reduced.
Moreover, the relevant data shows that there is an absolutely safe distance for civilian power supplies. As long as the distance from the power supply is more than 50 cm, the radiation value is zero when measured with a radiation measuring instrument. Therefore, as long as it is not Lying directly on the floor to sleep will not be harmed by radiation. In addition, there is currently no evidence that the thermal field generated by electric floor heating can affect the body.
Generally speaking: the thermal radiation produced by water geothermal is not the harmful radiation that people think in traditional consciousness, it is just a way of heat transmission, therefore, it will not cause any harm to the human body. Although electric geothermal generates some electric and magnetic fields, because it is a low-frequency power source and is protected by an insulating layer, the radiation generated is even lower than that of an electric blanket, so there is no need to worry.
3. Why do some people feel uncomfortable in a heated room?
Since geothermal does not cause radiation hazards to the human body, why do some people feel uncomfortable in a geothermal room? This has a lot to do with interior decoration materials.
The floor used in general households is mainly composed of composite boards. In the production process, substances containing formaldehyde and benzene are used to make the floor waterproof and moth-proof. Including the process of painting and assembling, the adhesives used contain certain chemical substances.
Even if the floor is not used, the floor tiles will inevitably contain a certain amount of radioactive substances, such as radon gas. The newly renovated home, even if there is no floor heating, will slowly volatilize formaldehyde, radon and other harmful substances all the time. The difference is that high-quality materials have low content of toxic substances and are less harmful to the human body.
Formaldehyde, benzene, radon, these names must be familiar to everyone, we have seen a lot in the news about decoration. Like formaldehyde, the main pollution source of interior decoration, when its concentration is slightly exceeding the standard, it is difficult for people to smell its odor, but after staying indoors for a long time, there will be symptoms of discomfort in the mouth, nose, eyes and throat; The smell of the nose indicates that the formaldehyde has exceeded the standard. If you stay in this environment for a long time, the human body will experience edema, pneumonia, and even death. Especially in children, it is easy to induce leukemia or affect the nervous system.
Opening a house with floor heating is equivalent to forcing out the toxic gases in the room and accelerating the volatilization of formaldehyde and radon. But after a period of time, less toxic gas remains in the floor. From this aspect, floor heating can also be regarded as accelerating the drive away of toxic gases.
When choosing home improvement materials, you must pay attention to choosing environmentally friendly and branded products, and don’t let inferior materials harm the whole family because of petty and cheap.
Another point to note: the northern region is very dry in winter, and the outdoor dust is large. When people return indoors after outdoor activities, the dust on their clothes will always be suspended indoors due to the thermal effect of geothermal energy. Within a height of about 1 meter, it will pollute the indoor air, especially for children, and it is easy to cause symptoms of dry mouth and even cause respiratory diseases.
Fourth, the correct use of geothermal heating is healthier
In addition to choosing a good floor, there are many more in daily life The details can determine whether geothermal heating is more healthy and environmentally friendly.
1. Control the indoor temperature and humidity.
After the heating is started, the home is warm, especially in the early stage of heating, the indoor temperature suddenly increases, which will make the human body very uncomfortable and prone to dizziness and sore throat. To prevent the appearance of these symptoms, you should first control the temperature in the living room and maintain proper humidity. Usually the room temperature is 18℃~24℃, and the humidity is 50%~60%. It’s best to buy a thermometer with a humidity measurement, so you can better monitor the temperature and humidity in the room.
The best way to control the temperature is to maintain ventilation, because many families have high room temperature in winter now, such a warm house has no trace of winter, so it is necessary to ventilate frequently to keep the body and nature the same The rhythm of this can be as close as possible to the unity of nature and man while maintaining the warmth of the room, so that the yang energy of the body tends to be in a closed state.
To control the humidity, you can often put a pot of water in the house, and you can also raise some green plants such as cacti, spider plants, and fortune trees. It is worth noting that there should not be too many plants, one or two pots in a room are enough, and the plants should be watered frequently.
Some people often use humidifiers to increase the humidity of the room, thinking that humidifiers are more convenient, but from the perspective of traditional Chinese medicine, it is better to use less. The reason is very simple, although the humidifier can provide a lot of moisture to the air, it is more mechanized. To give a simple example, if you use a humidifier for 1 hour, the humidity in the air has already met the needs of the human body. If you continue to humidify, the air humidity will be too high, and some moisture will naturally be absorbed by the body. Body dampness, if there is too much dampness in the body, it is likely to form phlegm dampness and affect the spleen and stomach. It is different if you put pots of water or plants in the house. It can decide how much water vapor to release according to the degree of drying, and the impact on the human body is not very large. Therefore, if you can not use a humidifier, it is best not to use it, and even if it is used, be careful not to keep it on.
2. Eat more moist, warm food.
Heating in winter often makes people feel very dry. In addition to keeping the temperature and humidity of the environment suitable, the human body should also pay attention to “moisturizing”. Studies have shown that the lack of water in the body is hindered by metabolism, which will accelerate aging. The elderly need more water because of the frequent urination. Usually eat more fruits, such as apples, pears, bananas, oranges and so on. At the same time, you can eat more moist and warm foods, such as sesame, radish, tomato, tofu, white fungus, etc., do not eat or eat spicy food, and do not drink or drink less alcohol. Heating can also cause dry skin and cause skin itching, so the water temperature should be controlled at about 32°C when bathing, and it is not advisable to use too much soap.
3. Keep the floor clean and remove dead spots.
Geothermal heating will cause the surface temperature to be relatively high. If the floor is not cleaned in time, the dust will easily evaporate into the air as the temperature rises, causing respiratory diseases. And as the room temperature rises, some bacteria will become active, which can easily induce diseases such as asthma. Therefore, it is necessary to keep the ground clean, and at the same time, the room should be cleaned frequently, especially some dead corner areas, so as to prevent the accumulation of dirt.
