"Why are you still on the floor heating, aren't you afraid of your child getting leukemia?" Aunt Li looked at her daughter-in-law with a shocked face.
Aunt Li's family are authentic northeasters, living in the northeast, the floor heating in the home is almost all standard, the family has used it for decades, after the daughter-in-law married in, although the family was separated, they did not live together, but also followed this living habit.
Recently, Aunt Li saw a piece of news, but let her sit on a needle felt, and finally removed the floor heating at home, and warned her daughter-in-law to stop using it, but when she came to her son's house today, she found that her daughter-in-law did not take it seriously at all.
"Mom, you have no head and no brain, let us close the floor to warm, this big winter does not need floor heating, how cold." The daughter-in-law complained.
"You young people are not obedient, people In Italy "experts" have said, floor heating will make children get leukemia, use more and kill sperm, no wonder you two have been born for three years without moving, maybe it is the strangeness of floor heating. ”
Aunt Li explained, but let the daughter-in-law misunderstand, she was deliberately provoking trouble, forcing herself to have a second child, so she slammed the door with her grandson, which made Aunt Li dumbfounded.
Aunt Li, who calmed down, also reflected: Is the floor heating radiation real or false?
First, the floor heating is slowly killing your children while it is warm?
Floor heating is a necessary facility for domestic northern families to spend the winter, but the unexpected "winter artifact", in recent years, has been frequently rumored to be harmful to health, some people say that floor heating will increase the risk of cardiovascular disease, induce leukemia, and some people say that heat radiation will affect eye vision, causing high blood pressure, all kinds of statements are out of the crowd, is it true or false?
Floor heating refers to the installation of heating equipment inside the floor, through heat radiation to the room heating facilities, and the installation of heating equipment is different, the type of floor heating is also different.
Generally speaking, the water floor heating is installed with hot water pipes, when the hot water flows through the pipe circulation, the heat will rise from the ground to the floor, the heat will be transported to the entire space, and the electric floor heating is equipped with cables, realizing the conversion between electrical energy and thermal energy, and radiating heat into the space.
There are many controversies about floor heating on the Internet, but Dr. Fang Yongjun of the Department of Hematology of Nanjing Children's Hospital responded: Floor heating does not cause leukemia.
The reason is that the electromagnetic radiation caused by electric floor heating, the study found that its radiation wave frequency is only 50 hertz, and the radiation frequency of various types of electrical appliances used daily in the general family is much higher than this, and some are even hundreds of thousands of times that of electric floor heating, such as: mobile phone frequency 900 megahertz, computer 333 megahertz.
If electric floor heating will cause cancer, then mobile phones and computers may be more harmful, but the current medical community has not found relevant evidence to support this argument.
Second, electric floor heating radiation and thermal effect radiation will also endanger the health of the body?
In the process of geothermal heating, it is true that thermal radiation is generated, but scientific research has also found a truth in nature: as long as the temperature of an object is above absolute zero (minus 273 degrees Celsius), thermal radiation is generated, and the object will also absorb the thermal radiation of other objects.
It can be seen that the radiation generated by the thermal effect in nature is actually negligible on the human body, otherwise human beings may not have the opportunity to develop.
In addition, the above content also mentions that the electromagnetic radiation of electric floor heating does exist, if the previous data is not detailed enough, then an experiment that CCTV has done for this purpose is very reliable.
In 2007, CCTV reporter and floor heating expert Dr. Wang Ansheng detected electromagnetic radiation in a woman's home, and the data showed that the amount of electromagnetic radiation in the environment at that time was 0.3 micro Tesla, and after the local warm temperature rose to 32 degrees Celsius, the electromagnetic radiation reached 0.08 micro Tesla.

In addition, the electromagnetic radiation of other electrical appliances in the environment is: electric iron 30-40, induction cooker 20, mobile phone call 0.39, TV 0.2, this set of data very clearly shows that the electromagnetic radiation of electric floor heating is much smaller than other types of common electrical appliances.
All kinds of data show that the electromagnetic radiation of electric floor heating will not cause harm to the human body.
Third, will the floor heating also kill sperm? You may have been fooled
Once upon a time, rumors flew all over the world, people heard the news of Coke killing sperm, WIFI killing sperm, bicycle sperm killing, etc., when the news came again, the floor heating became the "sperm killer" this time!
Medical research has found that the testicles in the high temperature state, sperm cells may be damaged, that is, what people call spermicidal, so doctors also recommend male friends, do not soak in high-temperature hot springs and saunas for a long time, and therefore, many people think of the heat of the floor heating, in the cold, the temperature of the floor heating is indeed "high temperature", long-term contact may really be able to kill sperm?
In fact, the temperature of the floor heating is basically within the control range, generally not too high, even if the "spermicidal" temperature is really reached, unless the testicles and the ground are in close contact for a long time.
In the case of a sauna, a high-temperature sauna can only damage sperm cells for half an hour, so it takes at least 30 minutes for the testicles and the ground to cause damage, but normal people do not seem to sit on the ground for a long time.
It can be seen that the killing of sperm in floor heating is also pure nonsense.
Fourth, the safe use of floor heating, these 3 points you must know
Although floor heating does not harm the human body, as a facility based on the family, it is also necessary to pay attention to safety when using it, and carry out health protection to the end.
1. Choose high-quality environmentally friendly flooring
Floor heating installation is generally under the floor, the quality of the floor is related to safety issues, if the quality is not good, light damage in the change of heat and cold, heavy will affect the service life of floor heating. In addition, some experts speculate that the rumors of floor heating causing leukemia may be the back of the pot for formaldehyde, so the use of environmentally friendly materials to eliminate formaldehyde from the root is also a health guarantee.
2, control the room temperature and pay attention to ventilation
In winter, the floor heating temperature can be controlled at 15-20 degrees Celsius, which is enough to maintain the indoor ambient temperature. Many people think that the use of floor heating in winter is for heating, and ventilation will reduce the temperature, which seems superfluous.
However, in a cold environment, floor heating is heated for a long time, if the air in the environment does not circulate, the air quality will be reduced, and the ambient humidity will gradually decrease and become dry, so it is necessary to maintain ventilation every once in a while, replace the air, and increase the humidity when necessary.
3, according to the national standards to buy, floor and floor heating must be matched
When buying floor heating, it must be in accordance with national standards, after all, it is a product that a family uses all year round, if there is a quality problem, it is small to add trouble to life, causing life safety problems to regret it, and the floor and floor heating are "neighbors", these two things must also be matched, otherwise the subsequent installation will cause trouble.
Floor heating warms our winters, and it's not that scary. In the era of information explosion, all kinds of rumors have become the topic of people's tea and dinner. However, in the face of rumors, people should also have a scientific and rational attitude to distinguish between true and false, rather than blindly accepting and blindly disseminating, which will only make the wrong information poison more people and mislead others. #Rumor Zero Plan # #守护银龄世界 #
