Could Your Phone Hurt You？ Electromagnetic Pollution

Cell phones are a very important presence in today's society. Mobile phone is just like a small computer, which can provide people with work, entertainment, study and other needs. The existence of mobile phones has undoubtedly accelerated people's communication and convenience. Although the advantages of the mobile phone are numerous, but it also has certain harm.
Speaking of the harm of mobile phones, many people may not care. Because the function of mobile phone is too powerful, so that people ignore the harm of mobile phone. Perhaps some parents often persuade their children to play less mobile phones, but most parents also use mobile phones for work and entertainment, so to reduce the harm of mobile phones to human body, not simply reduce the use of mobile phones, but correct and scientific use of mobile phones. After all, work and study are inseparable from mobile phones.
1. What is electromagnetic radiation?
The harm of mobile phones generally comes from the electromagnetic wave it radiates, because electromagnetic wave is a kind of invisible energy body, so it generally does not attract people's attention. Electromagnetic radiation is to point to the electromagnetic field that electricity and magnetism produce commonly, the spread of electromagnetic field resembles water current, wave one wave diffusion, and do not see to touch.
In people's cognition, radiation generally includes non-ionizing radiation and ionizing radiation, among which, non-ionizing radiation includes radio waves, microwave, infrared ray, etc. Since such radiation and other energy will be converted into heat after entering the human body, ionizing radiation will not appear. These include X-rays and gamma rays, which destroy atoms and strip them of electrons, so ionization can be very dangerous.
2. Is non-ionizing radiation harmful to human body?
Despite the advances in technology, there is still no concrete answer to the question of whether non-ionizing radiation is harmful to humans. Although there is no evidence that non-ionizing radiation is harmful to human health, the issue remains controversial. In fact, the study of electromagnetism began in 1996, but there was no conclusion because of the complexity and difficulty of the electromagnetic wave.
The influence of electromagnetic wave on people is generally divided into thermal effect and non-thermal effect. The general thermal effect refers to the conversion of electromagnetic wave energy into heat after entering the human body. Since the transmitting power of mobile phone is small, it will not affect the human body. And non-thermal effect refers to the human body long-term exposure to low thermal effect of electromagnetic, human body may appear other physiological effects. Non-thermal effects are also troublesome to study because they can affect so many people.
There have been many studies on the dangers of cell phones, but the conclusions have been polarizing. Some classify mobile phones as possible carcinogens, while others believe they can inhibit tumor growth under the skin. Because of the possibility of both studies, there is no obvious tendency to draw conclusions about mobile phones.
3, mobile phone radiation standards
Out of the need to protect human health, but also considering the importance of mobile phones to people, international organizations also customized standards for mobile phones. The standard addresses SAR, or magnetic fields generated by communications devices, on human health. In addition, taking into account the differences of people in different countries and their mobile phone usage habits, international organizations also conducted more rigorous studies and finally obtained the required SAR value.
4. What should we do?
The importance of mobile phones is self-evident, but the harm of mobile phones to people is also obvious. Perhaps the radiation produced by mobile phones is not harmful to human body, but the existence of mobile phones has formed people's habits of not exercising, lowering their heads, staying up late and so on. Therefore, for the use of mobile phones, people should weigh the advantages and disadvantages, not only to maximize the benefits of mobile phones, but also to reduce the harm of mobile phones to people.
