In practical use, the radiation of mobile phones is also related to the distance between mobile phones and base stations, the geographical environment around users, the setting of base stations and other factors. Generally speaking, the closer a mobile phone is to a base station, the less radiation it will have, and vice versa. At the same time, it should be clear that the radiation of mobile phones with better quality produced by regular manufacturers is relatively small.

Harm of mobile phone radiation:
1. Affect deep sleep and easily cause excessive fatigue. A study jointly conducted by karolinska institutet, Uppsala University and Wayne State University in Michigan found that people who use mobile phones before going to bed enter deep sleep for a longer time than ordinary people, and the duration of deep sleep is shorter, thus affecting the self-recovery function of the human body at night.
Professor Bengert Janez, who is in charge of this research, believes that radiation may activate the stress mechanism of the brain. "This will improve people's alertness and attention, thus reducing drowsiness."
2. It will reduce immunity. In order to study the effect of mobile phone radiation on immune function, some medical researchers put the receiver in the ears of pregnant mice, completely simulating human conversation. Thirty-two pregnant rats with balanced weight were randomly divided into four groups. One group did not receive electromagnetic radiation from mobile phones (control group), and the other three groups received low, medium and high intensity radiation from mobile phones (experimental group). The pregnant rats in the experimental group started from the day of conception.
2 1 day, radiotherapy 3 times a day. After normal delivery of pregnant rats, the content of immunoglobulin in peripheral blood of pregnant rats and newborn rats was determined. The conclusion is that the electromagnetic radiation of mobile phone does damage the lymphocytes of pregnant mice and newborn mice, which leads to the decrease of immunoglobulin content and immune function, and it is related to the radiation time.
