How to use mobile phones for better health and safety is worth learning
4hw.com.cn: mobile phones have gradually entered our lives with the development of the times, bringing great convenience to our lives. For example, it is convenient for parents to communicate with their children, and they will often receive SMS messages to deliver blessings on holidays, which makes Internet access faster. According to statistics, about 3 billion people in the world use mobile phones, three times the number of smokers. China has a population of more than 1.3 billion, and mobile phone users have exceeded 700 million, that is to say, at least one of the average two people has a mobile phone. As the most frequently used digital products, many people are almost 24-hour mobile phones. For the safety of mobile phone use, professionals also give several suggestions.
1. Keep the phone at least 5cm away from the body when talking. Because 5 cm away from the body, the intensity of electromagnetic field amplitude of mobile phone is 1 / 4 of the original, and 9 cm away from the body, its intensity is only 1 / 50 of the original. So it's best to use speakers or headphones. In both cases, the radiation of mobile phone is only 1 / 100 of that of standard mobile phone.
2. If you have to carry a mobile phone, make sure that the key area is facing the body and the back is facing the outside of the body. In this way, the transmitted electromagnetic field can be far away from your body.
3. When talking, change your body direction regularly. This will disperse the radiation the body is exposed to. In addition, when the other party picks up the phone, put the mobile phone on the ear to reduce the radiation of electromagnetic field.
4. In addition to not walking back and forth, mobile phones should also be avoided in cars or trains. Because at this time, the cell phone constantly tries to connect the interrupted signal, which will increase the radiation to the maximum value.
5. Text more and call less. This will reduce the contact time between the phone and the head.
6. When sleeping, don't put your cell phone next to your pillow. Pregnant women should not use it.
7. It's better not to make a phone call when the cell phone is about to run out of power or charging.
Use conservatively to reduce damage
cut a long story short. Use less mobile phones to 'cook telephone gruel'. When you are ready to talk for a long time, you should use fixed phones or headphones instead. If you have to use a cell phone for a long time to talk directly, you should also use another ear every 1-2 minutes to answer the call, so as to avoid long-term radiation to one side of the brain.
Don't hang on your chest or waist. Often make the mobile phone lean on the waist or chest, the radiation it produces will affect people's fertility and cardiovascular function. It's best to put your mobile phone in your carry on bag and try to put it on the outer layer of the bag. If you have to carry a mobile phone with you, make sure that the key area is facing the body and the back is facing the outside of the body.
Call less where the signal is weak. When the signal is poor, the power of the mobile phone will increase automatically, resulting in the increase of its radiation intensity. Based on the same principle, using a mobile phone in a small and closed environment such as an elevator will also increase its radiation intensity.
Put it on your ear after you connect it. When the mobile phone is in standby mode, the radiation is very small, and when the mobile phone number has been dialed out but has not been connected, the radiation is the largest, which is about three times of that in standby mode. At this time, keep the phone away from the head, and call again after an interval of about 5 seconds.
Wear metal eyeglasses and don't call mobile phones. This will obviously lead to the enhancement of electromagnetic field and the increase of radiation absorption rate of users. It's better not to talk for a long time, or listen to it on both sides.
Use a line headset. Earphones can not directly 'eliminate' radiation, but they can isolate the human body from the radiation source. In this case, mobile phone radiation is only 1% of the standard mobile phone. In comparison, the wire earphone has less radiation than the Bluetooth earphone.
