Television radiation
Keep a certain viewing distance. The radiation range of TV generally refers to the length. The radiation range of LCD TV is generally within 2 meters, while the viewing distance of flat-panel TV over 42 inches is 2~3 meters, which will not be affected by radiation. In addition, watching the big screen at close range for a long time will cause visual fatigue, so consider the size of the room when buying, not just the big picture. Generally, the viewing distance is between 2 and 2.5 meters, and you can choose a 29-inch product; 2.5~3 meters, 34-inch products can be selected, and 37-inch or 40-inch products can be selected above 3.5 meters.
Reducing dust means reducing radiation. LCD TV is covered with dust. Many people think it's just a health problem. The fact is not so simple. Studies have proved that dust is an important carrier of electromagnetic radiation. If LCD TV is not wiped frequently, even if it is turned off, electromagnetic radiation will remain in the dust, which will continue to cause harm to health. Therefore, it is best to wipe the LCD TV regularly to remove dust, and at the same time, it will also remove the electromagnetic radiation trapped inside, which can effectively prevent radiation from harming health. In addition, dust will often overload electronic components, circuit boards and radiators, which will eventually lead to increased power consumption and even burn out electronic components.
Let the green plants share the radiation. Any animal, plant and human body have the natural ability to absorb radiation, so you can put some green plants next to the LCD TV to reduce radiation. However, there are some restrictions on placing green plants next to LCD TVs, because many LCD TVs are not waterproof, and the circuit board inside the heat dissipation grid will directly contact the outside air. If hydroponic plants or too many green plants are placed next to LCD TV, it will seriously affect the safety and service life of electrical appliances. Therefore, it is best to place drought-tolerant green plants such as cactus, cactus or aloe near LCD TV.
Turn off the TV to prevent radiation accumulation. Although the radiation of LCD TV is small, it still exists. Therefore, when the LCD TV is suspended, it is best not to put it in standby state, because it can produce weak electromagnetic field and radiation accumulation for a long time.
Computer radiation
The first trick: For busy people, the easiest way to resist computer radiation is to drink 2-3 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.
The second measure: do skin care isolation before surfing the internet to effectively prevent environmental pollution and radiation; Secondly, after the computer is used, many particles of electromagnetic radiation will be adsorbed on your face, so you should wash your face with clear water in time, which will reduce the radiation by more than 70%.
The third 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 can't be too dark, so as not to affect the effect because of low brightness, which is easy to cause eye fatigue.
The fourth 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 fifth measure: the location of the computer is very important. 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.
The sixth 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.
Seventh 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.
Don't let the electrical appliances pile together.
Do not concentrate household appliances or use them together frequently, especially televisions, computers, refrigerators, etc., which should not be concentrated in the bedroom to avoid exposure to excessive radiation.
Don't stay behind the computer.
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.
Absorb electromagnetic waves with water
Maintain a good indoor working environment, such as comfortable temperature and clean air. Because water is the best medium to absorb electromagnetic waves, you can put more bottles of water around the computer. However, it must be plastic bottles and glass bottles. Never use a metal cup to hold water.
Reduce standby time
When the electrical appliance is suspended, it is best not to let it stand by for a long time, because it can produce weak electromagnetic field and radiation accumulation for a long time.
Wash your hands and face in time
There is a lot of static electricity on the surface of computer screen, and the collected dust can be transferred to the exposed parts of face and hands. After a long time, it is easy to cause macula and pigmentation, and even skin lesions appear in severe cases. So wash your face and hands in time after use.
supplement nutrition
Computer operators should eat more carrots, Chinese cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal liver, lean meat and other foods to supplement vitamin A and protein in the human body. You can also drink more tea, tea polyphenols and other active substances in tea are conducive to absorbing and resisting radioactive substances.
Answer the phone. Don't be impatient.
When a mobile phone is connected and charged, it releases the largest electromagnetic radiation, so it is best to answer the phone after the phone rings for a second or two. Don't answer the phone while charging.
The radio measured a safe distance.
Any electrical appliance will produce electromagnetic radiation as long as it is energized, from air conditioners, televisions, computers, microwave ovens, humidifiers to hair dryers, mobile phones, chargers and even wiring boards, but the amount of radiation produced by various electrical appliances is not the same.
