In the north, heating through floor heating is becoming more and more common. Floor heating is considered to be a comfortable heating method. Therefore, it is increasingly favored by users. However, the spread of this heating method threatens the health of people and causes people to start worrying. The following Xiaobian introduces six hazards to everyone.
Warm six hazards
1, to warm or cause children suffering from leukemia
Wechat said: Medical research has shown that long-term exposure to geothermal heating radiation will change blood, lymph and cell protoplasm. According to a study by an Italian expert, more than 400 children in the country suffer from leukemia each year. The main reason for this is the heat of residence, which has led to severe heating radiation.
Expert opinion: Error
I have been in medical practice for more than 20 years. I have never met or heard that warming causes children with leukemia at outpatient clinics and academic conferences. The pathogenesis of childhood leukemia has been widely recognized as being caused by physical factors, chemical drugs, ionizing radiation, and genetic factors. Among them, ionizing radiation includes nuclear radiation, X-rays, etc. Medically, it has been confirmed that it can cause bone marrow suppression, cause gene mutations, and lead to the occurrence of leukemia. However, it has not been heard that fever caused leukemia.
2, can induce cancer and accelerate cancer cell proliferation
Wechat said: Radiation pollution from geothermal heating will affect the body's circulatory system, immune, reproductive and metabolic functions, and in severe cases it will induce cancer and accelerate the proliferation of human cancer cells. According to research data from Switzerland, residents living in residential areas with hot heating have a 7.4 times higher risk of developing breast cancer. The results of a sample test conducted by the Texas Cancer Medical Foundation in the United States showed that people living in heat-heated places grew their cancer cells 24 times faster than the average person.
Expert opinion: Error
The causes of cancer are related to environmental pollution, chemical pollution (chemical toxins), ionizing radiation, free radical toxins, microorganisms (bacteria, fungi, viruses, etc.) and their metabolic toxins, genetic characteristics, endocrine imbalance, and immune dysfunction. The growth of cancer cells is mainly related to the growth of blood vessels around the cancer cells. If the blood supply to the surrounding blood vessels is good, “nutrition†is sufficient, and the cancer cells grow faster, and on the contrary grow slowly. However, there is no scientific confirmation that the growth rate of cancer cells is related to the temperature in vitro.
3, affect the human reproductive system
Wechat said: The main manifestations are men's reduced sperm quality, pregnant women's spontaneous abortion and fetal malformations.
Expert opinion: Error
This argument is too far-fetched. The reduction of sperm quality is related to long-term sedentary and varicose veins, and it also has a certain relationship with the external environment temperature, but it also takes a long time and obviously exceeds the body temperature, reaching forty to fifty degrees Celsius. For example, long-term in the sauna environment will indeed affect the sperm quality. However, the temperature of the warm environment is only over 20 degrees Celsius, and it will not affect the quality of sperm. There are also many factors affecting pregnant women's abortion and fetal malformation, including chromosomal abnormalities, endocrine abnormalities, genetic diseases, drug abuse, and exposure to toxic and hazardous substances. There is no scientific basis to confirm that it may be related to the heating of the ground.
4, can cause children's mental disabilities
Wechat said: According to the latest survey, of the 20 million children born each year in China, 350,000 are children with defects, of which 250,000 are mentally handicapped. Some experts believe that geothermal heating radiation is also one of the influencing factors. The World Health Organization believes that in addition to the adverse effects of electromagnetic radiation from computers, televisions, and mobile phones on the fetus, geothermal heating radiation is also an important culprit in infant maldevelopment.
Expert opinion: Error
There is no scientific basis for verifying that children’s intelligence, development, and warmth are related to this type of heating. After room temperature rises, furniture and other decoration building materials emit toxic and harmful substances such as benzene and formaldehyde, which are generally considered to be harmful to the human body. However, this is not directly related to whether or not it is warm.
Excluding the influence of temperature, according to the rumors of the Internet, the radiation of warmth will cause children to become mentally disabled. The first thing to do is to determine whether there is radiation in floor heating. At present, households use water heaters. Hot water flows across floors and cement. It should not produce radiation.
5, affect the cardiovascular system
Wechat said: To warm the cardiovascular system, manifested as palpitations, insomnia, bradycardia, reduced cardiac output, sinus arrhythmia, leukopenia, decreased immune function. If a patient with a pacemaker is in a geothermal heating environment, normal pacemaker use may be affected.
Expert opinion: Error
Cardiovascular diseases are related to long-term high blood pressure, blood viscosity, smoking and drinking and other bad habits, environmental pollution, lack of exercise and many other factors. If a patient with a pacemaker is in a geothermal heating radiation environment, it will affect the normal use of the pacemaker. Is it true that all hospitals do not dare to use heating during the winter in cardiac medicine?
6, adverse effects on the visual system
Wechat said: Because the eyes belong to the body's sensitive organs to geothermal heating radiation, excessive radiation of geothermal heating radiation can cause vision loss, cataracts and so on.
Expert opinion: Error
Environmental factors are also the main cause of decreased vision, mainly in close-range operations and poor operating conditions. In addition, they are affected by diseases and genetic factors. There are also many causes of cataracts, including age-related degeneration of crystals, metabolic diseases such as diabetes, trauma, congenital diseases such as viral infections, long-term use of hormone drugs, genetic factors, radiation factors, and complications of eye diseases. Radiation factors such as intense ultraviolet radiation, electric welders, boiler workers, etc., are susceptible to cataract under special circumstances, but have not heard or encountered cataracts and decreased vision due to warmth.
Floor heating features
1, comfortable and healthy, strong health care
Floor heating belongs to the radiation heat radiation on the ground. It lays pipes under the indoor surface and uses water as the medium to heat the surface. The benefits of this cooling method are twofold. On the one hand, it gives people a feeling of cold feet and head, which can improve blood circulation, promote metabolism and meet health standards; on the other hand, heat rises from the surface and can destroy the living environment of parasites such as ticks. The ground is sterilized, and the rising hot air will not cause contaminated air and is healthy and comfortable.
2, save space, beautify the room
Water floor heating is installed underground. After installation, an exquisite thermostat is only exposed on the wall. Now many families have installed radiators. In recent years, though the appearance of the radiator has been improved, it is more exquisite than before, but after a long time, it will inevitably be out of date, affecting the overall appearance of the home style.
3, environmental protection and energy saving, good stability
In spite of the need for continuous heating for a long period of time, the floor heating requires only temperature control after heating, which results in less power consumption and about 30% energy saving than electric floor heating and radiator heating. At the same time, water is warm and water is used as a heat medium, and the stability is good.
4, long service life, high safety factor
Basically, water and floor heating have the same life span as a building for up to 50 years. When it is used, there is basically no safety problem. The long life of plumbing has greatly reduced the problems caused by the use of ordinary heating equipment, and saved additional costs incurred during secondary replacement.
Editor's summary: The six major hazards to the ground heating are introduced here, and hope to help everyone. If you want to know more about yourself, you can follow the information on this site.
