in the information technology era, whether you are a student, office worker or retiree, you will inevitably be exposed to computers for a long time every day. Computers not only bring us convenience, but also bring us worry. Radiation is the most important point. Cactus can absorb radiation. Drinking some green tea every day can resist computer radiation… We can always hear all kinds of rumors about computer radiation in life. What are these rumors.
rumor 1: Cactus radiation protection
placing one or two pots of cactus next to the computer can help the human body absorb the radiation released by the computer as little as possible. Because cactus grows in a place with strong sunshine, it has a particularly strong ability to absorb radiation.
truth revealed:
a computer is placed there, electromagnetic radiation is emitted in all directions, and the strength of electromagnetic wave is mainly determined by the computer itself, and cactus can not be shielded or adsorbed.
rumor 2: put a few bananas on the table to relieve eye discomfort
people who often work in front of the computer often feel dry and painful eyes. Therefore, put a few bananas on the computer table. The potassium in the bananas can help the human body excrete excess salt, make the body achieve potassium sodium balance and alleviate eye discomfort.
truth disclosure:
multi supplement β- Carotene is beneficial for patients with vitamin A deficiency, but it will not have additional benefits for people without vitamin A deficiency. Most people’s dry eyes caused by sitting in front of the computer for a long time are caused by visual fatigue. Just pay attention to rest for about 15 minutes every 45-60 minutes to avoid excessive eye use.
rumor 3: do a good job of skin care isolation before surfing the Internet
do a good job of skin care isolation before surfing the Internet, which can effectively prevent radiation. In addition, after the computer is used, many particles of electromagnetic radiation will be adsorbed on the face. Wash your face with clean water in time, which will reduce the radiation by more than 70%. The main source of radiation in the 2227733311 computer circuit is similar to that in the 2227733311 computer circuit.
rumor 4: the placement of the computer is very important
try not to make the back of the screen face the place where there are people, because the back is the strongest radiation of the computer, followed by the left and right sides, and the front of the screen is the weakest. Subject to being able to see the words clearly, it should be at least 50 cm to 75 cm away, which can reduce the damage of electromagnetic radiation.
truth revealed:
computer monitor is only a part of the computer. The radiation generated is limited, and the radiation depends not only on the position of the monitor, but also on the position of the chassis.
rumor 5: install a computer special color filter on the display screen to reduce radiation
when operating the computer, it is best to install a computer special color filter on the display screen to reduce the harm of radiation. Do not place miscellaneous metal objects indoors to avoid re emission of electromagnetic waves. When using the computer, adjust the brightness of the screen. The greater the brightness of the screen, the stronger the electromagnetic radiation.
truth revealed:
color filter plate can only filter out part of visible light. The computer radiation we refer to is generally radio wave and radio frequency electromagnetic band, and the color filter plate can’t work. Placing metal objects around will have a certain impact on the distribution of electromagnetic field, but it is often very little.
rumor 6: pay attention to indoor ventilation
the computer screen can produce a carcinogen called brominated dibenzofuran. 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.
truth revealed:
brominated dibenzofuran is the product of oxidative coupling of plastic flame retardant polybrominated diphenyl ether PBDE. This oxidation process is more common in plastic combustion and rarely occurs in daily use. Therefore, in general, the amount of brominated dibenzofuran in plastics is very small, and it will not be released into the air, which has little impact on people.
pay attention to indoor ventilation. It’s wrong to push the harm to the computer.
rumor 7: resist computer radiation, drink 2 to 3 cups of green tea and eat an orange every morning.
the simplest way to resist computer radiation is to drink 2 to 3 cups of green tea and eat an orange every morning. Vitamin A can not only synthesize rhodopsin, but also make the eyes see more clearly in dark light. Therefore, green tea can not only eliminate the harm of computer radiation, but also protect and improve vision.
truth revealed:
green tea is indeed rich in β- Carotene (the precursor of vitamin A), but carotene is a fat soluble substance and less dissolved in tea soup. Therefore, green tea is not the best source of vitamin a supplement. Moreover, generally speaking, the daily diet of normal people can supplement enough vitamin A or vitamin B β Carotene.
rumor 8: eat more foods rich in vitamin A, C and protein
pay attention to eating more foods rich in vitamin A, C and protein such as carrots, bean sprouts, tomatoes, lean meat and animal liver as appropriate.
truth revealed:
food nutrition collocation should pay attention to balance, meat and vegetable collocation. If you ignore the intake of other nutrients in order to eat more of these foods, it will be more than worth the loss.
rumor 9: new computers should be purchased as much as possible
new computers should be purchased as much as possible, and do not use old computers. The radiation of old computers is generally severe, which is 1 ~ 2 times that of new computers under the condition of the same distance and similar models.
truth revealed:
this theory seems to think it is an advertisement for selling computers – the difference between new and old computers is mainly in performance. The radiation level may indeed be different, but the argument that the radiation of old computers is 1-2 times that of new computers is too groundless.
