Case: Pregnant woman’s cell phone does not leave her hand, the fetus stopped developing Ms. Wang is already 3 months pregnant, the family paid extra attention, Ms. Wang took time off early to go home to wait for delivery. With the elderly taking care of the family, Ms. Wang did not even get out of bed and stayed in bed holding her cell phone and tablet every day for a day. When she was 4 months pregnant, Ms. Wang went for a maternity checkup and found that the fetus was significantly smaller compared to its normal size, and later found that the child had stopped developing. Playing with cell phones and tablets is not the root cause of Ms. Wang’s fetus stopped developing we have no way of knowing, however, the doctor reminded that pregnant women should not leave their cell phones during pregnancy, or prolonged exposure to WI-FI signals, because this exposure will cause harm to their health. Study 1: Pregnant women often play with cell phones babies are born prone to hyperactivity Many pregnant mothers are confused about whether cell phones have an effect on them. Some people say that the radiation effect of cell phones on people is relatively small and almost none for the mother, but others say that if you use cell phones regularly, cell phone radiation has a negative effect on the attached fetus. It has been scientifically proven that if a pregnant mother plays with her cell phone a lot, it may cause her child to be born with ADHD. A recent Yale University research institute has shown that if a mother is exposed to cell phones during pregnancy, the cell phone radiation can affect the healthy development of the fetus’ brain and lead to the development of ADHD. Although many people have known for a long time that the fetus may be adversely affected by cell phone radiation, this study is the first time that it has been scientifically confirmed. Therefore, the conclusion that pregnant women often play with cell phones, for the healthy development of the baby is a negative impact is scientifically proven. Study 2: Cell phone ringing can scare the fetus Researchers at Wyckoff Heights Medical Center found that cell phone ringing can scare the fetus and disrupt its sleep (waking) cycle. The researchers followed 28 obstetrics and gynecology residents in the second trimester, i.e., seven to nine months of pregnancy, and asked them to carry a cell phone or pager with them and place it close to the fetus’ head, with the machine ringing five times every five minutes. During this time, the researchers used ultrasound to observe the fetus’ reaction. The results showed that the fetus showed startle reflexes, including turning its head, opening its mouth or blinking, when the bell rang. Previous studies have shown that residents have higher-than-average rates of pregnancy complications, including preterm delivery, high blood pressure and low birth weight, when they are pregnant and usually carry a cell phone or pager with them. The new findings are not to say that ringing cell phones pose more risks during pregnancy, “but we can say with certainty that frequent cell phone and pager use disrupts the normal behavioral cycle of the fetus,” the researchers were quoted as saying by American Healthy Living News. How to use a cell phone properly during pregnancy Like televisions, computers, and microwave ovens, cell phones emit low levels of non-ionizing electromagnetic radiation. Non-ionizing electromagnetic radiation is much milder than electromagnetic radiation; whereas ionizing radiation comes primarily from radioactive sources such as x-rays, radiation therapy machines and CT scans and has been determined to be harmful to fetal development. Non-ionizing radiation is less likely to harm the developing fetus because it is at the lower end of the electromagnetic spectrum. Studies have shown that cell phone use by pregnant women for short periods of time is not a health hazard. However, it is best for pregnant women to use cell phones with some caution because humans have not been using cell phones for long enough to understand what the consequences of long-term use will be. Therefore, it is recommended that pregnant women should pay attention to the following matters when using cell phones: 1. Use the cell phone as little as possible When using it, the call time should be short, and try to send text messages or use a landline instead. 2, use when the cell phone signal is strong The value of the energy radiated by the cell phone depends on the strength of the signal. The stronger the signal, the less energy needed to talk on the phone, so to reduce radiation, it is best to use the phone when the signal is strong. Try not to use the phone when the signal is bad, you can find a better signal place to call, for example, outdoors or close to the window. 3, reasonable use of headphones Try to increase the distance between the head and the phone to reduce the head by radiation. 4, do not move to talk Mobile phone is best not to walk while playing. Because the cell phone in the process of moving, need to find the signal source again, which will increase the intensity of radiation.
