What should computer families do to have children?
Can pregnant women use computers?
Many women use computers in their work and life. When they are preparing to become pregnant, they are often worried about whether the computer may cause damage to the fetus.
Obstetrics and gynecology experts tracked during pregnancy and found that two women had long-term exposure to computer screens, and they both had births. They did not have a bad family history and did not abuse drugs during pregnancy.
So experts doubt that it could be caused by electromagnetic radiation from computer screens?
Only one thing is certain, the VDT time is directly proportional to the harm it brings.
The impact of video-to-screen (VDT) radiation on reproductive health has been widely reported in various newspapers, magazines, and the mass media, but less data have been reported from the perspective of medical streaming specialty.
When answering such questions, I often say that there is no authoritative conclusion about the harm of computer radiation to the fetus, and that the net working time should be minimized in the first trimester.
More specific failures to elaborate in the consultation responses may disappoint many consultants.
The results of the professional survey were: a controlled medical record study was performed on 1583 pregnant women, and the OR value of spontaneous abortion was 1.
2. However, in pregnant women exposed to VDT for more than 20 hours per week, the OR value of spontaneous abortion is 1.
8. It shows that the risk of spontaneous abortion tends to increase when exposed to a large number of contacts.
Some research results suggest that VDT is associated with congenital defects in offspring, with an OR value of 1.
6, and when the VDT operation time is greater than 10 hours per week, the OR value increases to 2.
0, when the weekly VDT operation time is greater than 20 hours, the OR value is 2.
3. There is a dose-response relationship, therefore, it is considered that the risk of birth defects in the offspring of VDT operations cannot be ruled out.
After the 1990s, the results of our research on this subject found that 1,529 VDT-operating women had prolonged menstrual cycles and increased menstrual blood, and their frequency was significantly higher than that of the control group.
(P <0. 01). The natural abortion rate of vdt working women was higher than that of the control group, (p <0. 05). It was also reported that survey results of reproductive function and offspring health of 361 women engaged in VDT and 484 of the control group showed that the incidence of spontaneous abortion and pregnancy with anemia was also higher than that of the control group. However, there are opposite findings. There is currently no unified understanding and no authoritative conclusion. In each study, other factors (such as living environment, diet, physical condition, etc.) cannot be ruled out. The number of people surveyed is too small, which can only represent the local situation of the survey. Only one thing is certain, the VDT time is directly proportional to the harm it brings. The OR value is a term in medical statistics. It is a statistical treatment of the research value to obtain a reliable value. For example, the incidence of abortion in women engaged in VDT is 10%, and the incidence of abortion in women engaged in non-VDT is 8%Can it be said that the abortion rate of women engaged in VDT is higher than that of women engaged in non-VDT? Can not draw such a conclusion, it must be processed statistically, and whether the comparison of the two rates is statistically significant. Foreign practice: Japan stipulates in labor protection that pregnant women should not participate in VDT work until the question of whether the abnormal pregnancy outcome is related to VDT. According to the existing research data, it is recognized that at least the time for pregnant women to participate in VDT work is generally limited to 15-20 hours per week. Authoritative conclusion: The radiation around the computer includes X-rays, ultraviolet rays, visible light, infrared rays, ultra-high frequency, high frequency, extremely low frequency, and electrostatic fields. But the intensity of their emission is very weak. Far below the standards required by China and the International Health Organization. Experts of the World Health Organization believe that there are many reasons for the pregnancy outcomes of pregnant women who affect computer operation, mainly due to work fatigue and excessive stress, followed by the very low frequency electromagnetic field from the computer. Computer radiation protection products, such as anti-radiation scarves, aprons, vests, screen coverings, radiation absorbing instruments, etc., have a protective effect on computer radiation. Experts believe that these protective products have no effect on display radiation and furtherIt is pointed out that even if some protective products can indeed reduce radiation, there is no practical value, because the electromagnetic field and radiation generated by the display are far from the exposure range allowed by national and international standards. Medical experts recommend: 1. Women of childbearing age who are engaged in video screen work need not worry about the impact of video screen radiation on the health of the next generation. Monitor radiation is not harmful to reproductive health. 2. Do not work more than 20 hours per week in front of the computer to prevent miscarriage. 3. Ventilate the working environment and keep the air fresh.4. There is no need to wear protective devices. 5, to avoid fatigue and excessive tension, maintain a happy mood, do not limit. 6, strengthen outdoor activities, pay attention to exercise. 7, regular check-ups, good health care during pregnancy, to avoid high-risk factors leading to mortality and birth defects. Based on the above, we recommend that you avoid repeated (more than 40 hours per week) contact with the computer during the first trimester (first 3 months). When you must use it, you can work every hour and get up to an object or window to breathe fresh air for 10 minutes, Wearing radiation-resistant clothing is also an option. Pregnant women's long-term exposure to the computer is not conducive to the development of voltage and is likely to cause miscarriage. The terminal of a computer is a monitor. Its principle is the same as that of a television. When the electron stream emitted by a wavelength ray tube hits a fluorescent screen, it can be converted into visible light. During this process, X-rays harmful to the human body are generated, but the glass cover outside the VDT can absorb a large amount of radiation. In fact, the human body is exposed to a small amount of radiation. However, an electromagnetic field will be generated near the VDT. In in vitro experiments, this electromagnetic field can interfere with cell metabolism and reproduction at the level of the cell membrane, thereby affecting the gradual normal development. The survey results show that among women who use computers for a long time, the incidence of early spontaneous abortion is higher. In addition, prolonged sitting in front of the computer in a fixed position will affect the cardiovascular and nervous system functions of pregnant women, and the pelvic floor muscles and levator ani muscles will be damaged as a result, affecting the smooth progress of delivery. Therefore, once a woman is pregnant, especially in the first trimester, she should avoid continuous operation of the computer. Pregnant women can watch TV at a distance of 2 meters from the TV. Generally should not exceed one hour. Related experts also believe that computer monitors can produce harmful radiation to the human body, but the casing can absorb most of the radiation. With statistics, the actual radiation dose received by the human body is 6 millirads, and the International Commission on Radiological Protection believes that: the entire pregnancyDuring the period of receiving X-ray doses should not exceed 1 rad, which is far from 6 mrad, so it will not cause adverse effects on the fetus. At the same time, some people also found that the use of computers in early pregnancy may increase the flow rate, which is mainly related to the electromagnetic field inserted around the computer. As for the possibility of teratogenicity, there is no large amount of clinical data to confirm it. Where is the radiation? In our daily life, radiation can be divided into two types: long-term clinical male infertility patients, there is an increasing trend. In addition to mental and physical causes, the environment is also an important factor. Studies in recent years have confirmed that one of the important factors for men's loss of reproductive ability is the discovery of reproductive dysfunction of the retina pill, which makes the sperm produced by the retina pill not high in quality or even no sperm. It has been observed that, in addition to known disease factors, there is also a little-known "electronic mist" that can cause disorders in the spermatogenic cells ("seed" cells), leading to a reduction in the number of sperm in the semen to azoospermia.The formation of an invisible "hidden killer" is threatening the young people's ability to regenerate. In recent years, scientists have discovered that various electronic devices, including air conditioners, electronic computers, refrigerators, color televisions, laser phototypes and electric blankets, etc., can generate a large number of different wavelengths during use and operation.And frequency in electromagnetic waves-"electronic fog". This electronic mist is full of space. It is an invisible, intangible, and inaudible thing, which can easily cause physiological disorders of the human body, which can cause headaches, insomnia, forgetfulness, abortion of pregnant women, and fetal dysplasia. According to a report by the United States Technical Evaluation Service in Washington, the electromagnetic waves emitted by household appliances and various electrical wires are harmful to human cells. People who are sensitive to the "electronic mist" can cause serious abnormalities in the spermatogenic cells in the insulin pill. When the effect of the electronic mist is cut off, three months can see the obvious changes in the spermatogenic cells and sperm production.
