As the saying goes: no gold is too small. Computer, as a modern high-tech products and electrical equipment, in bringing more convenience to people's lives, high efficiency and joy at the same time, there are some adverse factors harmful to human health.
The computer on human health hazards, from the type of radiation, mainly including computers in the work of electromagnetic radiation (various electromagnetic rays and electromagnetic waves, etc.), sound (noise), light (ultraviolet, infrared radiation, as well as visible light, etc.) and other types of radiation "pollution".
From the point of view of the degree of harm, there is no doubt that electromagnetic radiation is the most harmful. Medical experts at home and abroad research shows that long-term, excessive electromagnetic radiation will cause direct harm to the human reproductive system, nervous system and immune system, is the main cause of cardiovascular disease, diabetes, cancer mutation and cause pregnant women miscarriage, infertility, teratology and other lesions of the triggering factors, and can directly affect the minors of the body's tissues and bone development, caused by visual acuity, memory loss and decreased hematopoietic function of liver In addition, electromagnetic radiation can directly affect the development of minors' body tissues and bones, cause vision, memory loss and decrease in liver hematopoietic function, and lead to retinal detachment in serious cases. In addition, electromagnetic radiation is also a hidden danger to information security, the use of specialized signal receiving equipment can be received and deciphered, resulting in information leakage and unnecessary losses. Excessive electromagnetic radiation will also interfere with other electronic equipment around, affecting its normal operation and electromagnetic compatibility (EMC) problems.
Therefore, electromagnetic radiation has been listed by the World Health Organization as the fourth largest source of environmental pollution following the water, air, noise, and become a hazard to human health of the invisible "killers", protection against electromagnetic radiation has become a priority.
Protection
Health countermeasures A plan of spear and shield
As the saying goes: the devil is one foot high, the road is high. In view of the harmful effects of electromagnetic radiation from computers, relevant international and domestic professional organizations and computer manufacturers have long since begun the work of protecting against computer radiation. After years of efforts, the computer and other electronic products manufacturing, radiation, energy saving, environmental protection, ergonomics and other aspects of the development of MPR, TCO, FCC, UL and other stringent certification standards to ensure that human health is not jeopardized. At the same time, the so-called energy-saving, environmentally friendly, radiation-free "green computer" also came into being in recent years.
The harm of electromagnetic radiation for the computer, can be taken to active protection and passive protection of two methods. Passive protection method, that is, in addition to improving the working environment and pay attention to the use of methods, take to frequent contact and operation of computers equipped with radiation clothing, radiation screen, radiation curtains, radiation glass and other measures to reduce or eliminate the harm of electromagnetic radiation; active protection method, it is from the computer electromagnetic radiation "source" -- monitor and chassis components. -- monitor and chassis and other components to start, it will eliminate or shielding.
One is to buy, that is, to buy the strength of manufacturers on the market to meet the "green computer" standard products; the second is DIY, that is, to buy through a variety of certification standards, "green" computer accessories, to create their own healthy computer. Here we will focus on how to choose to meet the radiation protection standard accessories to DIY healthy computer.
When using the computer, to adjust the brightness of the screen, in general, the greater the screen brightness, the stronger the electromagnetic radiation, and vice versa, the smaller. However, it should not be adjusted too dark, so as not to affect the effect of too little brightness, and easy to cause eye fatigue.
When operating the computer, pay attention to the screen to maintain an appropriate distance. The closer the screen, the greater the electromagnetic radiation suffered by the human body, so the better is 0.5M away from the screen.
In addition, in the operation of the computer, the face will be adsorbed a lot of electromagnetic radiation particles, to wash your face with water in a timely manner, which will reduce the radiation received by more than 70%.
There is another kind of tea
Commonly used computer in 83% of the people feel eye fatigue, 64% often feel shoulder pain, in addition, many people have tears, loss of appetite, sore throat, cough, chest tightness and other symptoms, and even slow action, memory loss.
Computer radiation not only jeopardizes human health, but also affects the quality and efficiency of work. For people who live a stressful and busy life, the easiest way to ward off computer radiation is to drink 2 to 3 cups of green tea and eat an orange every morning. Tea is rich in vitamin A original, it is absorbed by the body, can be quickly converted into vitamin A. Vitamin A not only can synthesize retinol, but also can make the eyes in the dark light to see things more clearly, so green tea can not only eliminate the hazards of computer radiation, but also to protect and improve eyesight. If you are not used to drinking green tea, chrysanthemum tea can also play a role in resisting computer radiation and regulating body functions.
The placement of the computer is very important. Try not to let the back of the screen toward the people, because the strongest computer radiation is the back, followed by the left and right sides, the front of the screen, but the weakest radiation. To be able to see the words prevail, at least 50 centimeters to 75 centimeters away, which can reduce the damage of electromagnetic radiation.
Pay attention to indoor ventilation: scientific research has confirmed that the computer screen can produce a carcinogen called brominated dibenzofuran. Therefore, it is best to install a ventilation fan in the room where the computer is placed, and if not, pay particular attention to ventilation when surfing the Internet.
Care: The most visible part of facial aging is the eyes, so it is especially important to take care of the eyes.
Eye cream: It has a moisturizing effect, and in addition to reducing the problem of dark circles and bags under the eyes, it also has the effect of improving wrinkles and fine lines.
Eye gel: and the effect of the eye cream is almost the same, but the gel texture rub up more refreshing, daytime use of the skin without the burden of feeling, most of the elimination of under-eye bags, dark circles, soothing eye skin symptoms.
