Does WiFi affect pregnant women? How much does WiFi radiation affect the fetus
4hw.org: it's undeniable that the existence of WiFi is a huge driving force in the era of Internet. Now people are coming to WiFi more and more. There are a lot of shocking articles about WiFi radiation on the Internet. So many expectant mothers, for the sake of baby's health, put an end to the existence of Internet at home. So pregnant women, as the most sensitive and special group, should be isolated from WiFi? Will WiFi cause harm to pregnant women? Let's see the following Make it up and have a look!
How much radiation does WiFi have
Experts say the intensity of radiation is inversely proportional to the distance, that is, the greater the distance between the human body and the wireless router in the home, the smaller the WiFi radiation received. The common wireless router in our home works between 30-500mw. According to the expert test, the power density of the wifi antenna is 9.1 MW / cm2 measured at 1 cm next to it.
What is the national safety standard for WiFi radiation
According to the safety upper limit established by the International Committee on non ionizing radiation, the safe radiation range of human body is 10 W / m2. The electromagnetic wave band used in WiFi wireless Internet is generally 2.4GHz to 5GHz, which is close to that used in mobile phones. At present, the radiation value of WiFi is usually at the level of milliwatts per square meter, far lower than the safety limit of 10 watts per square meter set by the International Committee on non ionizing radiation.
Does WiFi radiation affect pregnant women
Robert Cleveland, a scientist from FCC's engineering and Technology Department, found in the test that the average radiation people receive in their daily lives is about one microwatt per square centimeter (one millionth of a watt). The safe radiation limit of FCC for WiFi frequency is 1000 microwatts per square centimeter, so even if multiple WiFi devices are used in a room, the radiation damage to human body can be ignored. Although WiFi radiation is not harmful to our ordinary people, will it affect the health of expectant mothers during pregnancy?
In nature, radiation is generally divided into two kinds, one is high-energy ionizing radiation, such as hospital X-ray or nuclear radiation. Ionizing radiation does great harm to human body. Therefore, expectant mothers in pregnancy must avoid exposure to X-ray and other radiation, but generally they will not be exposed in daily life; the other is non ionizing radiation, the most common in life is general electrical appliances The generated electromagnetic radiation belongs to non ionizing radiation, such as microwave oven, refrigerator, mobile phone, computer and WiFi radiation that people use every day. According to the current impact of electromagnetic radiation on human body, only 24 hours of continuous exposure to this radiation environment, it will take hundreds of years to cause harm to human body. At present, according to the tests of relevant experts and clinical medical research, there is no evidence that the daily non ionizing radiation (i.e. the radiation emitted by electrical appliances in daily life) will lead to the increase of the abortion rate of pregnant women and the rate of fetal deformity, and will not lead to the low birth weight of newborns. As a result, expectant mothers during pregnancy do not need to worry too much about the harm that WiFi radiation can do to them.
FCC: Federal Communications Commission. To coordinate domestic and international communications by controlling radio, television, telecommunications, satellites and cables, and to be responsible for the authorization and management of radio frequency transmission devices and equipment other than those used by the federal government.
How to prevent radiation in pregnant women
1. The wireless router should be far away from the bedside
Although WiFi has little impact on human body, the wireless router in home should be installed as far away from people as possible, not near the bedside or on the desk, and the mother to be should try to avoid close and long-term contact.
2. Purchase electronic products through regular channels
As we have just introduced, non ionizing radiation is produced by electronic devices in our life, such as microwave ovens, refrigerators, televisions, mobile phones, routers and other electronic products. Both at home and abroad, electronic products have strict requirements and monitoring. Therefore, when purchasing electronic devices, especially wireless routers, mothers to be must purchase products produced by regular companies, so as to ensure safety.
3. Reasonable precautions
For the living radioactive materials, the principle of "radiation protection and safety optimization" can be adopted by mothers to be. For example, when using a mobile phone to receive and make a call, use a long-term headset, do not put the mobile phone on the head of the bed, and turn off the wireless router at night.
4. Avoid excessive anxiety
For expectant mothers in pregnancy, it is inevitable to worry about their own and fetal health. But if the expectant mother's excessive anxiety affects her digestive system and sleep, it will really affect the health of the fetus. Therefore, whether the expectant mother is in the workplace or waiting for childbirth at home, she should take appropriate outdoor activities to breathe fresh air, which is very beneficial to herself and the fetus.
