Hold the iPad drama, brush the iPhone to see friends, between the phone and the computer to pass files …… With the development of mobile Internet, a variety of wireless terminals are emerging, WiFi has become an indispensable part of people’s lives. However, there are many rumors that WiFi has radiation, affect reproductive health, or can lead to infertility or fetal malformation! Is this true? Experimental evidence that WiFi affects human health and reproduction? There is not enough evidence WiFi is called wireless fidelity, which is actually the conversion of wired network signals into wireless signals. It can be said that WiFi is actually a small local area network, mainly for data transmission. As a wireless device, WiFi has a transmitter, which does produce electromagnetic radiation to the surrounding area. Recently, for whether WiFi affects health, leading to infertility and other issues, some people abroad have done related experiments: Denmark, five female high school students will be 12 pots of water celery in two groups in two rooms, the temperature, the same amount of water, one room has two routers, the other room is not. The experiment lasted 12 days. The experiment showed that the germination rate of the seeds in the room with WiFi was 85.3%, while the germination rate of the seeds in the room without WiFi was 95.4%. There are many factors that can affect seed germination, and this experiment did not rule out other factors. Previously, there was also a report on an Argentinean study that said WiFi on laptops can reduce male sperm motility. In vitro exposure of semen to radiation for four hours resulted in decreased sperm motility and increased DNA fragmentation compared to the absence of radiation, according to the report. The experiments and reports have not been well received by academic experts. In vitro sperm exposure to WiFi radiation is different from the in vivo situation, and one experiment alone is not representative. Neither of the above two experiments can confirm that WiFi affects human health and causes infertility, and more research is needed to verify this. Domestic experts who have long been engaged in radiation research said that the most common wireless router, its operating power between 30-500 milliwatts, power and power density than ordinary cell phones is also small. Try to avoid all kinds of radiation in life In fact, radiation is everywhere in life, in addition to WiFi, computers, cell phones, televisions, microwave ovens, printers, etc. will produce electromagnetic radiation, but the radiation power of these appliances are not large, the impact on the human body is minimal, basically in the safe range, can only affect the surface of the skin. And, as long as it is not close to the body, the impact on the human body can be completely negligible. “Parents can not be overly worried or alarmed, as long as the pre-conception checkups, regular maternity checkups to the regular hospital during pregnancy, you can easily and happily nurture a healthy baby.” However, usually also pay attention to the superimposed effect of radiation. Electrical appliances should be turned off when not in use, including the electrical plug; try to avoid the simultaneous use of cell phones, microwave ovens and other radiation equipment and radiation superimposed effects; a variety of office equipment, cell phones, etc. should try to avoid prolonged use.
