Do you want to turn off WiFi at night? How much influence does WiFi radiation have on human body?
4hw.com.cn: now many of our daily necessities are starting to be smart. They all need WiFi to connect with each other, and people are increasingly inseparable from WiFi. However, many people are worried about the harm of WiFi radiation to their bodies, and they will choose to turn off WiFi before going to bed at night. So the question is, how much harm WiFi radiation does to people, and whether to turn off WiFi at night? Let's share the answer with Xiaobian!
No router off, the side effects are really great! For example, many people can't sleep at night, can't get up in the morning, and their head is still a little dizzy... Xiaobian carefully considered it, because the reason must be: the signal is too good, so you always hold your mobile phone, can't sleep, and move less!
Well, the WiFi router is actually innocent, because the radiation generated by the WiFi router is "non ionizing radiation", and the radiation dose is very low, almost negligible.
According to the regulations of the authority, the safe exposure limit of different body parts to radiation is not higher than 1.6w/kg.
It is found that the "radiation value" caused by WiFi signal to human head is only 0.0057w/kg, which is more than 280 times lower than the limited safety value!
So, turn off the router, mainly depends on when you are ready to sleep, but also depends on when you want to get up.
Of course, if you don't, the table is too monotonous.
Note that this is only about decoration, not radiation.
The computer has radiation, but it belongs to "non ionizing radiation", which is not harmful to the body, so it is not necessary to prevent it.
The most common harmful radiation in life is X-ray. For example, the X-ray machine and CT in the hospital have a small amount of ionizing radiation, but they are still in the controllable range.
Of course, we have to think about mobile phones. The signal is too good. It can't stand it!
In fact, a cell with a communication base station can live in, because:
1. Although the base station has "electromagnetic radiation", it is harmless to people
China has strict requirements for the management of base station electromagnetic radiation, and the current national standard "electromagnetic environment control limit" is far lower than the international standard limit.
Take the GSM base station with 900MHz frequency as an example, the standard limit of our country is 40 microwatts per square centimeter, which is more than 10 times lower than the standard of European developed countries (450 microwatts per square centimeter)!
Therefore, there is no need to worry about the radiation of the base station.
2. The more base stations, the less radiation
The radiation intensity of the mobile phone is closely related to the signal intensity of the base station. The farther away the mobile phone is from the base station, the weaker the signal, and the greater the transmission power required.
It's like a conversation between two people. The farther away you are, the louder you need to shout. The closer you are, the more you can whisper.
If you think about it further, you can see that the density of the base station is high, the signal is good, and the reception of the mobile phone is easy, so at this time, no matter the base station or the mobile phone, it doesn't have to work so hard, and the radiation is correspondingly reduced.
In a word, the communication base station has nothing to worry about. If it's built near the community, it's actually hello. Hello, everyone.
