The radiation waves emitted by the computer are often ignored by people. According to the international MPR Ⅱ radiation safety regulations: in the 50cm distance must be less than or equal to 25V / m radiation exposure.
But you know how much computer radiation? Computer radiation: 1, keyboard 1000V/m2, mouse 450V/m3, screen 218V/m4, host 170V/m5, Notebook 2500V/m
In addition, the radiation electromagnetic waves on the human body has eight major harm:
1, cellular cancer promotion
2, hormonal irregularities
3
4, dementia triggers
5, abnormal pregnancy abnormal birth
6, high blood pressure heart disease
7, electromagnetic wave allergies
8, an increase in suicides
Using computers you have to pay attention to the four major hazards of computer radiation are as follows:
1, the computer radiation pollution will affect the human body's circulatory system, immune, reproductive and metabolic functions, serious also induce cancer, and will accelerate the proliferation of cancer cells in the human body. `
2, affecting people's reproductive system is mainly manifested in men with reduced sperm quality, pregnant women with spontaneous abortion and fetal malformation.
3, affecting people's cardiovascular system manifested as palpitations, insomnia, some women's menstrual disorders, bradycardia, decreased cardiac blood volume, sinus arrhythmia, leukopenia, reduced immune function.
4, the people's visual system has a negative impact on the eyes belong to the body's sensitive organs of electromagnetic radiation, excessive electromagnetic radiation pollution will also have an impact on the visual system. The main manifestation of vision loss, causing cataracts and so on.

Uncovering the X-files of computer "radiation"
As the saying goes, "There is no such thing as gold. 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 also some harmful factors 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 source of radiation, they include CRT monitor radiation sources, chassis radiation sources, as well as speakers, printers, photocopiers and other peripheral equipment radiation sources. One of the CRT (cathode ray tube) monitor imaging principle, determines that it is difficult to completely eliminate harmful radiation in the use of the process. Because it is working, its internal high-frequency electron gun, deflection coil, high-voltage packages and peripheral circuits, will produce such as ionizing radiation (low-energy X-rays), non-ionizing radiation (low-frequency, high-frequency radiation), electrostatic fields, optical radiation (including ultraviolet, infrared radiation and visible light, etc.) and other rays and electromagnetic waves. While the liquid crystal display is the use of physical properties of liquid crystal, its working principle is completely different from the CRT display, inherently radiation-free (negligible), environmentally friendly "health" type of display; chassis internal components, including high-frequency, power consumption of the CPU, with a large number of internal integration of transistors of the main chip of the card The various components inside the chassis, including high-frequency, power-consuming CPU, various boards with a large number of internal transistors integrated into the main chip, with high-speed DC servo motors of the CD-ROM drive, floppy drive and hard disk, a number of cooling fans and transformers inside the power supply, etc., when the work of the low-frequency electromagnetic radiation and noise interference. In addition, external speakers, copiers and other peripheral equipment radiation source is also a not to be ignored "source".
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 the 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.
Anti-computer radiation has a trick
When using a computer, it is best to be equipped with a good quality radiation screen in front of the monitor. Pay attention to eat more carrots, bean sprouts, tomatoes, lean meat, animal liver and other foods rich in vitamin A, C and protein, often drink some green tea and so on.
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 not only can eliminate the hazards of computer radiation, but also can 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.
Computer radiation is inevitable, but can be reduced. First of all, should be as far as possible to buy new computers, generally do not use the old computer, the old computer radiation is generally more powerful, in the same distance, the same type of conditions, is generally a new computer 1-2 times. Operation of the computer is best in the display on a computer special color filter to reduce the harm of radiation, do not place indoor idle metal objects, so as not to form the re-emission of electromagnetic waves. When using the computer, to adjust the brightness of the screen, in general, the greater the brightness of the screen, the stronger the electromagnetic radiation, and vice versa, the smaller. However, can not be adjusted too dark, so as not to affect the effect of too little brightness, and easy to cause eye fatigue. Also note that 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 half a meter away from the screen.
Computer use, the face will adsorb 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%.
The cactus can attack the bad guys, but there is also a benefit! It is said that placing a cactus in front of a computer desk will help reduce radiation.
People who use computers often will feel discomfort in the eyes, vision loss, and fatigue.
Eat foods that are good for your eyes, such as eggs, fish, cod liver oil, carrots, spinach, groundnuts, pumpkins, goji berries, chrysanthemums, sesame seeds, radishes, and animal livers.
Eat more calcium-containing foods, such as soy products, bone broth, eggs, milk, lean meat, shrimp and so on.
Attention to vitamin supplementation: eat more fresh fruits and vegetables containing vitamins.
Attention to enhance resistance: eat more food to enhance the body's ability to resist disease, such as mushrooms, honey, fungus, kelp, mandarin oranges, jujubes and so on.
Eat some anti-radiation food: although the computer has less impact on human health, it should be prevented. Drinking tea can reduce the harm of radiation, tea in the lipopolysaccharide has anti-radiation effect. Spirulina, sea buckthorn oil also has anti-radiation effect.
Additionally, you should wash your face after using the computer, and you should pay attention to exercise in general.
Computer placement is very important. Try not to let the back of the screen toward the place where there are 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. In order 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.
Facing the computer for a long time is not good, what should we do? In fact, four cups of tea a day, not only can fight against radiation, but also to protect the eyes.
1. A cup of green tea in the morning:
Green tea contains potent antioxidants and vitamin C, not only can remove free radicals in the body, but also to secrete the hormone against stress. The small amount of caffeine contained in green tea can stimulate the central nervous system and invigorate the spirit. However, it is best to drink it during the day to avoid interfering with sleep.
2. A cup of chrysanthemum tea in the afternoon:
Chrysanthemum has the effect of clearing the eyes and liver, and some people simply use chrysanthemum with goji berries to drink, or add honey to chrysanthemum tea, which is helpful in relieving depression.
3. fatigue a cup of wolfberry tea:
Wolfberry is rich in beta carotene, vitamin B1, vitamin C, calcium, iron, with liver, kidney, eyesight. Its own sweet flavor, you can make tea can also be like raisins as a snack, to solve the "computer people" eyes astringent, fatigue are effective.
4. Evening cup of cassia tea:
Cassia seeds have heat, eyesight, brain marrow, town of liver gas, benefit the role of the muscles, if there is constipation, you can also drink after dinner, for the treatment of constipation is very effective.
Some of the most suitable tea for computer users to drink, or snacks, not only can help you fight against radiation, but also to protect your eyes, anti-irritation it.
Mung bean barley soup
Mung bean can clear the heat and detoxification, diuretic swelling, barley can strengthen the spleen to stop diarrhea, light body gas, for often need to stay up all night workers or upset, dry mouth, constipation, acne, in addition to eating more vegetables and fruits and replenish the water, the mung bean barley soup as a snack to eat, in addition to the summer is very helpful.
Duzhong Tea
Duzhong has the effect of tonifying blood and strengthening the muscles and bones, often sedentary, back pain is very helpful, men and women can drink, if the female friends can also be at the end of the physiological period with the four soup to take together.
