In order to make our mobile phones fully charged during the day, we will directly put the mobile phone on the bed before going to bed at night to charge, but many people are worried that the mobile phone is radiation to the human body, so the mobile phone on the bed before going to bed at night will not cause harm to the human body?

Radiation is divided into ionizing radiation and non-ionizing radiation, of which ionizing radiation is harmful to the human body, such as hospital X-rays, while non-ionizing radiation is harmless to the human body, such as mobile phones, wireless networks and various household appliances at home. Mobile phone radiation is not ionizing radiation, so it will not cause harm to the human body.

But to be safe, avoid charging your phone by the bed. Although the explosion of the mobile phone while charging is a small probability time, it can also happen, so it is best to stay away from yourself when the mobile phone is charging, and even unplug the charger when the mobile phone is full of electricity to avoid an explosion.

In fact, the biggest harm to us is that the mobile phone is charged at the bedside, and it will be more frequent to look at the mobile phone and play the mobile phone. For many people who are not very strong in self-control, it is difficult to put down the mobile phone and sleep at ease before going to bed, and the content of the mobile phone attracts people to look and play, so that they often play the mobile phone in the dark, which has no small impact on people's vision and cervical spine. Even because of playing mobile phones and staying up late, the impact on the body is even greater. At the same time, when sleeping, if the phone ringtone at the head of the bed suddenly rings, it will also affect people's heart and nerves to varying degrees.
radioactive
First of all, electromagnetic radiation is generated by signals, and the peak value reaches its maximum when the mobile phone makes and receives calls, sends and receives text messages, or uses the mobile network to surf the Internet and exchange data with the base station.
The mobile phone charger itself has only a small amount of electric field radiation, and the magnetic field radiation that is the most harmful to humans is not large. However, if the mobile phone has been placed very close to people, whenever the mobile phone has calls, text messages, and signal instability need to find signals, it will emit a lot of electromagnetic radiation. So if it is charged, it is best to turn it off.
The national safety standard is the electric field extreme value of 4000v\/m and the magnetic field extreme value of 0.4μT. However, the magnetic field radiation that we usually connect to the mobile phone is as high as 30, 40 or even more than 100 μT, so many people complain that the phone will have a headache for a long time because of this. The WTO says children with long-term exposure of 0.3-0.4 μT have a much higher risk of developing leukemia.
In fact, the electromagnetic radiation is very low in the case of human impact is very small, and so far, the world's academic scientists are also in the discussion and discussion, so far and buy medicine 100% to determine whether it is because of mobile phones caused by brain cancer and leukemia, but as far as possible principle of life in the high radiation electromagnetic field is very important.
The charger has no radiation and has no effect on people.
As long as the mobile phone is on, it means that it has been transmitting signals to the base station, and the radiation of the mobile phone in the charging state is more than 50 times that of the ordinary state.
