Nowadays, when many people arrive in a strange place, the first thing they want to ask is "Are you there?" Some people even bluntly said that you need WiFi even if you don’t have a boyfriend.
Nowadays, buses, subways, restaurants, and shopping malls are all covered with WiFi. When we go home and sleep at night, the WiFi is not turned off. We live in an environment surrounded by WiFi 360 degrees without blind spots. Have you ever thought about whether our exposure to WiFi all day long will have an impact on our health?
Chinese people’s worries about WiFi
#In Fuzhou, China, a husband went from house to house because his daughter-in-law was pregnant and was afraid that radiation would affect her health. They asked neighbors to turn off their WiFi from house to house. One neighbor had their door knocked on four times a day.
This incident has attracted the attention of many domestic netizens, and everyone is concerned about whether WiFi will have an impact.
People are not only worried about WiFi. There are also various claims on the Internet that WiFi affects sperm health and that WiFi can cause cancer. Some people say that at least turning off WiFi when sleeping at night can reduce radiation. So, what is the truth?
CCTV Reveals the Harm of WiFi to the Human Body
The "" program specially conducted an experiment to address the issue of WiFi's impact on health. The results confirmed that in the maximum transmission state of WiFi, the maximum power is 14.32dbm, which is only equivalent to 1/40 of a one-watt light bulb.
The Caenorhabditis elegans, which is very sensitive to environmental changes, was exposed to a WiFi signal with a strength of 31.9 volts per meter. The nematodes were not interfered by WiFi and moved freely.
It can be seen that WiFi will not affect human health, and there is no need to turn off WiFi when sleeping at night.
WiFi is harmless to ordinary people, but is it harmful to pregnant women?
Researchers pointed out that when pregnant women are pregnant, their own hormones will increase, and the body is equivalent to being in a very good protective environment and will not be interfered by WiFi, including At present, there is no data in the entire international academic research to illustrate the impact of WiFi on health.
Therefore, pregnant women do not need to deliberately avoid WiFi, including wearing some radiation-proof maternity clothes. In fact, it is unnecessary.
Do you need to turn off your mobile phone at night?
In addition to WiFi, some people are also worried about harm to their health. For example:
·The lower the mobile phone signal, the greater the radiation, which affects health;
·The lower the power of the mobile phone, the greater the radiation, which will affect health;
·While charging the mobile phone, the radiation will become greater, affecting health;
· If you sleep with your mobile phone next to your bed, you will get brain cancer.
In fact, the radiation of a mobile phone is only related to the signal strength and has nothing to do with the amount of power or whether it is charged. And no matter how low the signal of a mobile phone is, the radiation it emits is extremely low and will not affect health.
Some studies have shown that the radiation signal of mobile phones is even lower than ultraviolet rays. If mobile phones can cause cancer, then the probability of causing cancer is higher when exposed to sunlight.
Therefore, there is no need to turn off your phone or turn on airplane mode when sleeping at night. Some people are afraid that mobile phone radiation can cause brain cancer, so they keep mobile phones away from the bedside. This approach has no practical significance in reducing radiation, but it can prevent you from being addicted to mobile phones and affecting your sleep, which is indeed helpful to your health.
Our worries about WiFi all come from our unknown knowledge of new things. But we cannot stand still because of worry, reject or prevent its development. We must use a scientific and rigorous attitude to dialectically analyze the problems we encounter in order to usher in a better life.
