In front of the computer for a long time what harm?
Computer host, monitor, mouse, keyboard and the surrounding equipment will produce radiation, eyes can not see, hands touch. According to scientific research shows that: computer-generated low-frequency electromagnetic radiation on the human body caused by the damage is hidden, the accumulation of people often (long-term) in the ultra-strong computer low-frequency electromagnetic radiation environment using the computer, leading to dizziness, headache, Tinnitus, brain cancer, breast cancer, blood pressure, abnormal blood pressure, chest tightness, bradycardia, bradycardia, heart failure, loss of vision, loss of appetite, fatigue, memory loss, some people hair loss, leukopenia, immunity, cataract, leukemia, , Heart rate reduction, sinus heart rate, male sperm quality, some women menstrual disorders, maternal abortion, stillbirth, fetal malformations, reproductive lesions, genetic lesions, cancer and other terrible diseases. People in the operation of the computer, the face will absorb a lot of electromagnetic radiation particles, often radiation will appear facial rash.
The studio should be kept dry and dry. ◆ lying on the table to sleep when you remember to turn off the computer, not just turn off the screen. Because the tummy when the head directly to the computer, just turn off the screen is unable to put an end to the radiation. ◆ Keep your skin clean. There is a lot of static electricity on the surface of the computer screen, the dust can be scattered to the face and hand skin exposed, a long time prone to rash, pigmentation, severe cases and even cause skin lesions. ◆ pay attention to nutritional supplements. In the screen before the working time is too long, the rhodopsin on the retina will be consumed, and the rhodopsin is mainly composed of vitamin A synthesis. Therefore, you should eat more carrots, cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal liver, lean meat and other foods to supplement the body of vitamin A and protein. Drink tea, tea, tea polyphenols and other active substances will be conducive to the absorption and resistance to radioactive substances. In addition, the cactus in addition to attack the bad guys, there is a benefit Oh! It is said that at the computer table placed a pot of cactus to help reduce radiation, and healthy and seductive, may wish to try ah!
Seeking adoption
A person working on a computer for five hours, the computer produces low-frequency radiation damage to the human body, the equivalent of a day of life loss. Computer-generated rays include visible light, radio waves, low-frequency electromagnetic waves, static electricity and ultrasound. According to the radiation is divided into free radiation and non-free radiation: free radiation from the tube; non-free radiation from the computer display electronic parts of the current and voltage. But no matter what kind of radiation, in the normal normal operation, its strength is not enough to cause harm to the human body. Although the computer radiation is not enough to harm the human body, but the choice of the computer is best to buy low-radiation display, in addition to reducing radiation, but also can eliminate the psychological burden. In addition, there are some measures that can make the computer radiation harm to the human body to a minimum: ◆ avoid a long time continuous operation of the computer, pay attention to the middle of the rest. The distance between the eyes and the screen should be 40-50CM, binocular vision or mild downward attention to the best screen. ◆ indoor light to be appropriate, to avoid direct exposure to light on the screen and produce interference light
