How harmful is computer radiation to human body?

Judging from the types of radiation, the hidden dangers of computers to human health mainly include electromagnetic radiation (various electromagnetic rays, electromagnetic waves, etc.). ), sound (noise), light (ultraviolet, infrared radiation and visible light, etc. ) and other radiation "pollution". What is the "magnetic radiation" generated by computers? Basic physics tells every middle school student that when current flows in a conductor, a magnetic field is bound to be generated in its external space, and magnetic lines with certain energy constantly flow from one magnetic pole to another, so we human beings live in such a natural and artificial magnetic field. If the magnetic field is too strong, it will cause "magnetic pollution" to the human body It has been reported in the literature: 1998 The World Health Organization lists five major effects of electromagnetic radiation on human body: First, electromagnetic radiation is the main cause of cardiovascular disease, diabetes and cancer mutation; Second, electromagnetic radiation does harm to human reproductive system, nervous system and immune system; Thirdly, electromagnetic radiation is the inducing factor of pregnancy abortion, infertility, teratoma and other diseases; Fourth, electromagnetic radiation directly affects children's development and bone development, leading to decreased vision, retinal detachment and decreased liver hematopoietic function; 5. Although electromagnetic radiation will reduce physiological function and make women's endocrine disorders and menstrual disorders, many media confuse "magnetic pollution" with the normal "magnetic effect". It should be recognized that these problems that are harmful to human body stem from excessive "pollution" of electromagnetic shielding materials. According to the data provided by many environmental protection materials, when the computer is running, the electromagnetic waves emitted by the chassis main body and the monitor will be the first measure to prevent computer radiation: putting a few pots of cactus next to the computer can effectively absorb radiation; The second trick: For busy people, the easiest way to resist computer radiation is to drink 2 to 3 cups of green tea and eat an orange every morning. Tea is rich in provitamin A, which can be quickly converted into vitamin A after being absorbed by human body. Vitamin A can not only synthesize rhodopsin, but also make eyes see things more clearly in dark light. Therefore, green tea can not only eliminate the harm of computer radiation, but also protect and improve vision. If you are not used to drinking green tea, chrysanthemum tea can also play a role in resisting computer radiation and regulating body functions. Spirulina and sea buckthorn oil also have anti-radiation effects. The third measure: do skin care isolation before surfing the internet. For example, the use of pearl membrane, the unique "South Pearl Cui Membrane" forms a layer of 0.00 1mm pearl membrane on the skin, which can effectively prevent environmental pollution and radiation; Secondly, after the computer is used, many particles of electromagnetic radiation will be adsorbed on the face. Wash your face with clear water in time, which will reduce radiation by more than 70%! The fourth measure: When operating a computer, it is best to install a computer-specific color filter on the display screen to reduce the harm of radiation, and do not place miscellaneous metal objects indoors to avoid the re-emission of electromagnetic waves. When using a computer, you need to adjust the brightness of the screen. Generally speaking, the brighter the screen, the stronger the electromagnetic radiation, and vice versa. But it should not be too dark, so as not to affect the effect because the brightness is too small, which is easy to cause eye fatigue. The fifth measure: you should try to buy a new computer, and generally don't use an old computer. The radiation of old computers is generally severe. In the case of the same distance and similar models, it is generally 1-2 times that of the new computer. The sixth trick: the location of the computer is very important. Try not to let the back of the screen face people, because the back of the computer has the strongest radiation, followed by the left and right sides, and the front of the screen has the weakest radiation. As long as you can see clearly, the distance should be at least 50 cm to 75 cm, which can reduce the harm of electromagnetic radiation. Seventh measure: pay attention to indoor ventilation: scientific research has confirmed that computer screens will produce a carcinogen called dibenzofuran bromide. Therefore, it is best to install a ventilator in the room where the computer is placed. If not, pay special attention to ventilation when surfing the internet. Eighth measure: Pay attention to eat more foods rich in vitamins A, C and protein, such as carrots, bean sprouts, tomatoes, lean meat and animal livers, and often drink some green tea. The ninth trick: people who often work in front of the computer often feel dry eyes and pain. Therefore, it is necessary to put some bananas on the computer desk. The potassium in banana can help the human body to discharge excess salt, make the body reach the balance of potassium and sodium, and relieve the discomfort of eyes. In addition, bananas contain a lot of beta-carotene. When the human body lacks this substance, the eyes will become painful, dry, dull and dehydrated. Eating more bananas can not only relieve these symptoms, but also relieve eye fatigue to some extent and avoid premature eye aging. According to incomplete statistics, 83% people who use computers often feel tired eyes, 64% people often feel shoulder pain, backache, and many people cry.
