Sihaiwang: for pregnant mothers, we should pay attention to everything and be careful. But in modern life, computers, televisions, mobile phones and so on all have more or less radiation. It is said that these radiation will have some adverse effects on the human body, especially for the early pregnant women, which will affect the normal development and growth of the fetus. In fact, does computer radiation really affect the fetus? Let's see what the experts say.
There are two ways in which computer radiation affects the fetus:
Saying 1: long term contact with computers is not conducive to fetal development, pregnant women should stay away from computers.
They believe that the terminal of a computer is a monitor, and its principle is the same as that of a television. When the electron stream emitted by a cathode-ray tube strikes a fluorescent screen, it can be converted into visible light. In this process, harmful X-rays will be produced, but the glass cover outside the VDT can absorb a lot of radiation. In fact, the radiation exposure to the human body is very small.
However, there are also low-frequency electromagnetic fields around VDT. In vitro, this electromagnetic field can interfere with cell metabolism and proliferation at the level of cell membrane, thus affecting the normal development of embryo.
However, it is necessary to distinguish ionizing radiation from non ionizing radiation. Ionizing radiation, such as X-rays, must be harmful to humans and embryos. Non ionizing radiation, such as infrared, microwave, radio, video display terminal, and daily electricity use, is still controversial whether the human body has gonadal toxicity, embryotoxicity or teratogenicity. But for the sake of safety, it is not suitable to carry out continuous computer operation for a long time during pregnancy.
Statement 2: computer radiation has no obvious effect on pregnant women and will not affect the fetus.
This side believes that although computer radiation exists objectively, it and electromagnetic pollution are two concepts. Only when it exceeds a certain intensity, it will have a negative effect on the human body. At present, the safety and health standard limit of electromagnetic radiation in China is less than 40 microwatts / square centimeter. As long as the computer is produced by a regular manufacturer, it must pass relevant tests, and generally there is no radiation problem.
It also said that the radiation of the computer was lower than that of the color TV. Some people have been using computers for a long time, and have dizziness, nausea and other symptoms. They are worried that it is caused by computer radiation. In fact, it is probably caused by high concentration of mind and too much pressure at work. There are many reasons that affect the pregnancy outcome of women, the most important one is work fatigue and over tension, the computer's extremely low frequency electromagnetic field is only the secondary reason.
In fact, it is not clear in the academic circles about the problem of "the impact of computer radiation on pregnant women". There is no clear statement that computer radiation will have adverse effects on the fetus. However, based on the self-protection consciousness of the mother, in order to give the baby a healthy start, many mothers still choose to stay away from the computer as far as possible.
Warm tips: sitting in front of the computer in a fixed position for a long time will affect the cardiovascular system and nervous system functions of pregnant women, and the pelvic floor muscles and anal levator muscles will also suffer from strain and affect the smooth delivery. So pregnant women should not sit for a long time, no matter whether they want to prevent radiation or not, but should ensure proper exercise.
