This paper lists six hazards brought by floor heating, such as radiation, cancer, cardiovascular system and reproductive system. The reading volume of this article is as high as one million, and it has been reprinted wildly by major websites, Weibo and friends circle. The article also uses words such as "Italian experts think" and "World Health Organization thinks", which makes many people very worried. Does floor heating really have radiation that will threaten human health? For a time, many users who installed the floor heating system fell into a panic. So, does floor heating really have radiation, which will threaten human health? Come and listen to experts to crush rumors!
Network floor heating is harmful to human body.
Hazard 1: geothermal heating radiation will change blood, lymph and cell protoplasm, leading to childhood leukemia.
Hazard 2: geothermal heating radiation will affect the circulatory system, immunity, reproductive and metabolic functions of the human body and induce cancer.
Hazard 3: Geothermal heating radiation will affect people's reproductive system, leading to miscarriage of pregnant women and fetal malformation.
Hazard 4: geothermal heating radiation will affect people's cardiovascular system, showing palpitations, insomnia, decreased immune function and so on.
Hazard 5: Geothermal heating radiation can lead to mental retardation of children.
Hazard 6: Geothermal heating radiation can lead to vision loss and cataracts.
The reporter interviewed more than 10 citizens. Many citizens are skeptical about this statement and think that the post is reasonable and should be cautious. During the interview, a community resident said that after reading the posts in the WeChat circle of friends, he was very worried that it would be really harmful and affect his family's health. Some citizens think it is nonsense, but the specific reasons are called "unclear" and "personal feelings".

Many medical experts say "there is no scientific basis"
Expert opinion: There is no scientific basis.
Gao Yuhuan, Director of Hematology Department, Fourth Hospital of Hebei Medical University
This statement has no scientific basis. As long as hot water circulates in the heating pipe to generate heat, floor heating will not produce radiation. If we have to say that leukemia has anything to do with floor heating, it can only be that the decoration materials contain toxic substances such as formaldehyde and benzene, and the evaporation of such toxic substances is accelerated after the heating temperature rises in winter.
At present, the cause of leukemia is not very clear. The main inducement is related to virus infection and ionizing radiation. It is often said that the surrounding radiation or radioactive sources can induce leukemia. It's also related to poisons. For example, some chemicals, such as hair dyes and rubber products, will contain toxic substances such as benzene, which will affect hematopoietic stem cells. Leukemia is also related to some genetic factors.
Expert opinion: It doesn't matter.
Ma Guogang, Director of Oncology Department of shishi city Third Hospital
Floor heating has nothing to do with the proliferation of cancer cells, so there is no such problem. Floor heating is water circulation heating, which will not induce cancer or cancer cell proliferation. It can only be said that some harmful substances in decoration materials will have an impact on tumors. For tumor patients, we don't recommend local hot compress, which will accelerate the blood supply of blood vessels around the tumor, but geothermal heating will not cause the problem of cancer cell proliferation.
Expert opinion: unscientific
Liu Chunying, honorary vice president of shishi city Second Hospital and director of andrology of integrated traditional Chinese and western medicine.
This statement is unscientific. First of all, there are many reasons that affect human reproductive system, which are mainly divided into two categories: environmental hormones and "electronic fog". As far as environmental hormones are concerned, such as pesticides, fertilizers, laundry detergent, etc. Estrogen will have a certain impact on the human reproductive system. At present, people's most used mobile phones will radiate to the human body, which belongs to "electronic fog" and will affect people's reproductive system.
Secondly, if the testicular temperature is too high, the number of sperm will decrease, but floor heating will not affect the testicular temperature, nor will it affect the human reproductive system.
Expert opinion: It doesn't matter.
Wang Lijun, Director of Cardiology Department of shishi city Third Hospital
This must have nothing to do with floor heating. Cardiovascular diseases are mainly related to age and heredity. In addition, some patients with hypertension and hyperlipidemia, obese people, regular smokers and sedentary people are also prone to cardiovascular diseases. Pacemakers are mainly affected by magnetic fields, such as mobile phones, and floor heating will not affect the use of pacemakers.
Expert opinion: it doesn't make any sense.
Director of Neonatal Department of Qiao Shishi Maternity Hospital
I've been a doctor for so many years, and I've never heard such a statement. It doesn't make any sense. Generally speaking, the impact on newborns is caused by drugs, toxic environment or air pollution. Newborns should be careful not to grow up in a newly decorated environment. Jiali needs more ventilation to keep the indoor air circulating. Ventilation is the best disinfectant. Adults should also pay attention to washing their hands frequently to prevent the virus from being transmitted to newborns.
Expert opinion: There is no basis.
Li Junhui, director of outpatient department of municipal eye hospital.
I haven't seen a patient with eye injuries caused by floor heating. There are many reasons for cataracts, which are mainly influenced by these factors: senile cataracts caused by age, complex cataracts caused by diabetes and inflammation, cataracts caused by trauma or congenital cataracts in children. I haven't heard of any cataracts caused by floor heating, which is unfounded.

Unfortunately, this kind of radiation is "lying down" unless it warms the ground.
Cui Minghui, a professor at the School of Architecture and Engineering, Hebei University of Science and Technology, said that floor heating is to evenly heat the whole floor by laying a heat medium under the floor, and then use different heat conduction methods to realize the warming of the whole space. "There are three ways of heat transfer: heat conduction, convection and radiation." Cui Minghui said that the heating effect of floor heating is actually a kind of thermal radiation. No matter what state the material is in, as long as it has temperature, it will radiate energy in the form of electromagnetic waves.
At present, there are two kinds of floor heating in the market: split floor heating and electric floor heating. Among them, in the liquid circulation system, hot water with the temperature not higher than 60℃ is used as the heating medium to heat the floor circularly in the heating pipeline, and then the room is heated by radiation. After the heat energy diffuses into the room through the floor, the temperature is between 24-26℃, and the highest temperature will not exceed 28℃. "The thermal radiation effect at this temperature is as warm as in the sun," Cui Minghui said.
As for electric floor heating, Cui Minghui said that the electrification will naturally generate electromagnetic fields, but the purpose of cable electrification is not to conduct electricity, but to make it heat, that is, to convert electric energy into heat energy, and this conversion efficiency reaches 98%-99%. When electrified, it will only generate a small amount of electromagnetic radiation, which is not enough to affect the human body. In addition, the floor heating used in urban housing is basically a circulating system. Electric floor heating is generally used in places where central heating cannot reach, such as villas.
In fact, Bian Xiao found that similar rumors can be traced back to at least last April, and many media have also refuted them. Comparing the current website of "Six Harms of Ground Heating" with the website of "Six Harms of Electromagnetic Radiation" in 2005, the expressions are almost the same except that electromagnetic radiation is replaced by heating radiation. In the article "Radiation in Life is Not Terrible" in the column "Verification" on June 24, 20 13, experts explained that "electromagnetic radiation" mentioned by people in daily life belongs to non-ionizing radiation, including electromagnetic fields generated by ultraviolet rays, visible light, mobile phones, computers, high-voltage lines, substations, mobile phone base stations and television broadcasts. , and less harmful. Ionizing radiation, including nuclear radiation, X-rays and neutron radiation, is harmful. Therefore, the six hazards of floor heating are purely rumors, and the owners need not worry too much.
