Core Tip: Recently there have been reports that long-term use of electric blankets will affect the female endocrine system, and even affect male sperm quality leading to infertility. Is the electric blanket really so scary? Experts told reporters that electric blankets do generate electric and magnetic fields after being energized, but below the environmental standards, it is recommended to cut off the power supply early when using electric blankets.
In the cold winter, warm blankets are always nostalgic, and electric blankets have become a “must have†for warm duvets, especially in the south, where electric blankets are used more widely. Recently, it has been reported that long-term use of electric blankets will affect the female endocrine system, and even affect the quality of male sperm resulting in infertility. Is the electric blanket really so scary? Experts told reporters that electric blankets do generate electric and magnetic fields after being energized, but below the environmental standards, it is recommended to cut off the power supply early when using electric blankets.
The electric blanket electric field is lower than the environmental standard. “The electric blanket contains electric heating wire, which is equivalent to the wire. After the electric current is applied, the electric resistance is generated by the electric resistance, so as to maintain the warmth. When the electric current passes through the electric heating wire, the magnetic field is surely generated, and an electric field is also formed. It should be noted that the magnetic field and electric field generated by the electric blanket after being energized are far below the environmental standard. The electric field specified by the environmental standard is 4kV/m, and if measured on the electric blanket, it is only about tens of volts/meter, both The gap between them is still relatively large. The magnetic field generated by the electric blanket is only about 1% of the environmental standard," Zhu Chongde, senior engineer of the Supervision and Management Department of Shanghai Radiation Environment Supervision Station told reporters.
It should be specially noted that although the electric field and magnetic field generated after the electric blanket is energized are far below the environmental standard, since the person is sleeping, it will directly contact the electric blanket. In addition, if the public keeps the electric blanket energized while sleeping, it will directly contact the electric blanket for a long time. There have also been reports in the medical field that the use of electric blankets for pregnant women within 1 month of pregnancy may also be one of the factors leading to their abortion.
Or affect the reproductive system and embryonic development Zhu Zhongde introduced that when the human body is sleeping, the back and the electric blanket directly "close contact", and the time is relatively long. Zhu Chongde also introduced in his paper "Electromagnetic Radiation Pollution and Protection" as a common source of power frequency radiation in household appliances, especially because the electric blanket is the most intense electromagnetic field and the longest duration of action. The source of radiation, so the question about whether electric blankets have adverse effects on human health, especially on offspring, has drawn people's attention. Epidemiological investigations have shown that the use of electric blankets in early pregnancy (within 12 weeks of gestation) is associated with an increased incidence of miscarriage. The use of electric blankets in early pregnancy is one of the risk factors for miscarriage.
Guo Lijie, a gynaecologist and obstetrician at the First Affiliated Hospital of Tsinghua University, explained that the study on birth defects in newborns in the United States suggests that radiation does not necessarily lead to neonatal malformations. China has defined toxic, harmful, and ray as adverse factors for neonatal defects. But specifically, how much this radiation may affect pregnant women or other people is still difficult to determine, and more than 60% of birth defects themselves cannot be found. From the perspective of birth defects, the most sensitive period is 5-13 weeks of pregnancy.
The testicles are more susceptible to the surrounding environment and are in a magnetic field. The radiation from the magnetic field will definitely have some effect on the human body. Previous studies on this subject have different conclusions from different topics. However, from the general trend of global research, the radiation of magnetic fields does have adverse effects on the reproductive system function of the human body. The Reproductive Center of Peking University Third Hospital Jiang Hui, director of the male department and doctoral tutor, introduced.
In addition, this is also related to the male's own physiological structure. The testis is the only gland in the body of the male body, while other glands are in the body. The reason is that the testicles are suitable for a relatively low temperature environment, generally about 35 ° C, and the average body temperature of the human body is generally around 37 ° C. In addition, the testicular gland tissue is also more susceptible to the surrounding environment. Some people may have hidden pills, which may lead to testicular infertility for a long time, because the internal temperature of the human body is relatively high, and the spermatogenic cells in the testis are destroyed, resulting in infertility.
Long-term use of electric blankets will put the testicles at a higher temperature. From this perspective, it does have a certain impact on male reproductive function. In addition, the use of electric blankets for a long time increases the temperature, which is not achievable by the surrounding air, and the relatively high temperature will also damage the testicles. However, as to the specific impact, it is currently uncertain. Because if you want to conduct experiments in this area, some are also against ethics. From the perspective of mechanism and general knowledge, there is still a certain impact on male reproductive function.
Jiang Hui also said that it is not only the long-term use of electric blankets, but also other lifestyles that affect male reproductive function, including frequent hot baths, saunas and so on.
â– Hot question and answer does not recommend children to use electric blanket Q children, the elderly and other special people is suitable for using electric blankets?
Guo Lijie: We do not recommend children to use electric blankets. If you drink more water at night, many children are easy to wet the bed, which is also a risk factor. In addition, children's skin is generally delicate, not suitable for use with electric blankets, if it must be used, should also avoid direct contact with the skin. From my personal point of view, it is not recommended for the elderly to use electric blankets, because there have been reports of burns on the electric blankets by the elderly. From a safety point of view, it is better to use them less.
Zhu Chongde: Under normal circumstances, the public should pay attention to check the packaging when purchasing, whether there is any person who indicates the discomfort.
You can continue your pregnancy with an electric blanket. Q If a pregnant woman uses an electric blanket without knowing her pregnancy, what should I do? What should I pay attention to?
Guo Lijie: The pregnancy process can continue, because there is no scientific research to prove that this will have a serious impact on the fetus, but it is still reminded that pregnant women should minimize exposure to computers, microwave ovens, etc. after pregnancy, because radiation may cause some adverse effects.
