Talking on the phone like this is harmful to your health

　　1. Hold the phone close to your ear when making a call

　　When a phone call is made but not connected, the radiation will be significantly enhanced. It is not a good habit to put the phone to your ear to wait for the call to be connected or to listen to ringtones. At this time, you should keep the phone away from your head and wait for about five seconds before talking.

　　Cause of injury: The first task of the mobile phone to make a call (calling call) is to initiate a call to the base station (send a signal through the mobile phone). As far as I know, the maximum measured power value of this call is 2 watts, which is the power of non-brand mobile phones, no matter how large. I suggest everyone that when we call someone (the caller), it is better to hold the phone in hand before the other party picks up the phone to talk. If possible, you can use hands-free, Bluetooth, or wired headsets. In this way, you can avoid a lot of radiation.

　　2. Private phone call: "Hide in the corner and whisper”

　　For calls involving private content, many people like to hide in the corner of a building to answer calls. When people whisper on their mobile phones or receive calls in public places, they often find an elevator or stairwell where no one is nearby to make a call, so as to avoid being disturbed by others.

　　Cause of injury: Generally speaking, the signal coverage in the corners of buildings is relatively poor, because radio wave transmission is in a straight line. When you are talking on a mobile phone in a corner, radio wave transmission will be very difficult. It must be constantly refracted back and forth to transmit information. This will increase the power of the mobile phone, thereby increasing the radiation intensity. For the same reason, you should also be careful when using your mobile phone when you are in a small and closed environment such as an elevator.

　　3. The weaker the mobile phone signal, the closer the ear is to the

　　When the cell phone signal is weak, many people will instinctively hold the phone as close to their ears as possible. When the signal is poor, the radiation from the mobile phone will increase. At this time, the antenna should be pulled out to improve the call quality and reduce radiation. You can also try to use separate headphones to reduce the contact between your phone and your body.

　　Cause of injury: As long as the phone is turned on, the phone will continue to emit electromagnetic radiation waves. Studies have shown that once electromagnetic wave radiation exceeds the limit, it can cause serious health problems in the human body. nerve Debilitating symptoms can even lead to damage or death of internal tissues of the human body in severe cases. Moreover, the greater the radiation power and the closer the distance, the greater the damage to the human body may be. According to the working principle of mobile phones, when the signal is weak, the mobile phone will automatically increase the emission power of electromagnetic waves, causing the radiation intensity to significantly increase. At this time, if you put your ears close to each other, the radiation received by your head will increase exponentially.
