How far is the mobile phone from the body to be safe? In life, I believe many friends have the habit of playing mobile phones before going to bed. Many people know that mobile phones are radioactive and stare at the screen of mobile phones for a long time. Next, I sorted out how far the mobile phone is from the body to be safe.
How far is the mobile phone from the body to be safe? 1 What is the harm of mobile phone radiation to human body?
Cell phone radiation is actually an electromagnetic wave, which is emitted by TV sets, microwave ovens, computers and sunlight. These electromagnetic waves are classified according to frequency from high to low. The higher the frequency, the greater the energy contained and the greater the harm to the body.
From high to low, electromagnetic waves are divided into radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X rays, gamma rays and so on. The frequency of radiation emitted by the mobile phone we often use is about 1GHz~300GHz, which belongs to the microwave band, far lower than the radiation generated by sunlight, and will not have much impact on the human body.
First, reduce the quality of sleep. Clinical studies have found that people who have been disturbed by mobile phone radiation for a long time have far lower sleep quality than those who have not been disturbed by mobile phone radiation. This is because cell phone radiation can stimulate the nervous system of the brain and keep the body awake, which leads to the decline of sleep quality.
The second is to affect the endocrine system. If you are exposed to mobile phone radiation for a long time, it will also affect the endocrine system function. Electromagnetic waves will affect the normal metabolic function of the body, thus causing endocrine disorders.
Third, it is harmful to head health. Cell phone radiation may even harm people's central nervous system and head health, causing headaches, dizziness, insomnia, dreaminess, hair loss and other symptoms.
How far is the mobile phone from the body when sleeping?
Because people often use mobile phones, the harm it brings will not have obvious influence on the body in a short time, but in the long run, the body is prone to all kinds of discomfort. So, how far is the mobile phone from the human body when sleeping?
Many people are used to putting their mobile phones under their pillows. In fact, this will lead to an increase in the transmission power and radiation of the mobile phone, which will easily affect the head health for a long time. Some people like to play mobile phones before going to bed, and finally put them near their bodies, while others are used to putting them at the bedside.
But in fact, the mobile phone should be placed more than 1.5 meters away from the brain, heart and other important parts to avoid electromagnetic interference; The distance between the connected or charging mobile phone and the human body should be more than 1.5 meters, and it is better to be far away, so as to ensure the quality of sleep and reduce the harm caused by radiation.
How far is the mobile phone from the body to be safe? 2. The mobile phone is an electromagnetic product, which radiates itself, but it spreads and affects us in a subtle way that the human eye can't detect. Of course, this process is long, but with the extension of time, our physical function will be damaged to varying degrees.
The radiation of mobile phone mainly depends on its antenna, design and other factors. 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. Don't use fake mobile phones easily, because they want to pursue the call effect and increase the transmitting power of mobile phones, thus generating greater radiation.
Cell phone radiation will affect people's nervous system function, immune system function, circulatory system function and life development function. Girls who like to hang their mobile phones on their chests are easily influenced by endocrine, leading to arrhythmia and menstrual disorders. Men who like to put their mobile phones in their trouser pockets will not only cause some diseases, but also reduce sperm activity by as much as 30%.
So you'd better turn off your cell phone when you sleep, because it has radiation. No matter which side you put it on the bed, it must be turned on at night. If the radiation is the least, it should be the heel. Don't put your mobile phone next to the pillow, but there is no authoritative data on the distance. Most people should use 1.5 meters.

Will affect the endocrine system.
Many people, especially girls, like to hang their mobile phones on their chests, but research shows that doing so will have a certain impact on the heart and endocrine system, even when the radiation is small, it will also have an impact on the human body. Therefore, people with bad heart and arrhythmia should pay special attention not to hang their mobile phones on their chests. Moreover, if endocrine function is affected by cell phone radiation, it will also lead to menstrual disorders in women.
2, it will also kill sperm, which will lead to other diseases.
Hungarian scientists have found that the number of sperm in men who often carry and use mobile phones will be reduced by as much as 30%, which may affect fertility. In addition, some British experts believe that mobile phones may induce Alzheimer's disease, Parkinson's disease, premature senility and amnesia.
3. It may lead to brain tumor or cancer.
Cell phone radiation is harmful to human head. It leads to the dysfunction of our central nervous system, causing headache, dizziness, insomnia and dreaminess. Although there is no scientific method to prove that cell phone radiation can cause brain tumor and cancer, it is internationally recognized that cell phone radiation is harmful to human body if it exceeds a certain intensity and lasts for a certain period of time.
Ways to avoid cell phone radiation
The health topic of mobile phone radiation has always attracted people's attention. We like mobile phones, but we should pay attention to their scientific and healthy use.
1. Try not to use mobile phones in some cases.
For example, if you have an ordinary mobile phone, you can choose a mobile phone to reduce the harm caused by mobile phone radiation. Avoid using mobile phones in rainy days, because rain will attenuate electromagnetic waves, greatly increase the radiation intensity of mobile phones and increase the radiation absorbed by the human body.
It is particularly important to note that some people should not use mobile phones, such as children, pregnant women, lactating and menstrual women, the elderly over 60 years old, heart patients, cataract patients and so on.
2. Don't put your mobile phone at your waist, and don't hang it on your chest.
The radiation range of the mobile phone is an annular belt centered on the mobile phone, so the human body and the mobile phone need to keep a certain distance. If you put your mobile phone on your waist, it will lead to infertility, and hanging it on your chest will affect your endocrine system and heart.
3. Don't get close to the mobile phone when it is connected.
When the mobile phone is turned on, the power will peak, so the radiation will be the strongest. When we turn on the phone, we should press the power button, then stay away from the phone and wait for it to turn on before using it. At the moment when the phone is connected, the radiation will suddenly increase, but it will decrease rapidly after a few seconds, so try to keep the phone away from your head after pressing Connect.
4. Don't use your mobile phone in the corner.
In general, the signal in the corner will be poor, and if you use a mobile phone in this place, the radiation will increase.
