The internet age allows people enjoy the magic of digital technology, but also will bring some health worries. At present, the health effects of computers and networks have attracted people’s attention.
First, the keyboard is a “garbage dump.” In the daily work process, many people may not realize that the frequent use of keyboard may lead to disease. At first, the keyboard a “garbage dump,” in which there are dust, hair, hairs, and eyelashes and so on. According to statistics, these dirt accumulation rates are increasing by 2 grams per month on average. In addition, the keyboard on the surface is covered with a large number of bacteria such as Streptococcus, Staphylococcus and so on.
Second, the hazards of radiation on the body cannot be ignored. A British study confirmed that low-frequency radiation from computer screens and magnetic field, will lead the 19 kinds of illnesses, including itchy eyes, neck and back pain, transient loss of memory, such as temper, and depression. Some people will have itchy eyes, or dry and sour, his eyes are just in the stage of functional impairment, but if you do not protect the eyes from now on, the eyes continue to be in a dry state for a long time, it will cause the shedding of corneal epithelial cells, resulting in the injury of device quality, making the symptoms further deteriorated and seriously affect vision.
In addition, neck muscles, soft tissue for a long time in tension or injury will cause the nape of the neck syndrome, if you are not treated early, the nape of the neck syndrome will develop cervical spondylosis. Moreover, long been engaged in computer work women, the risk of breast cancer is 43%higher than the average non-computer work practitioners. A study of Taiwan suggests, in Taiwan about more than 300 million computers and in computer work mostly are women. In front of the computer for a long time, breast cancer will increase the chance of falling ill; and there is high breast cancer risk in premenopausal women than postmenopausal women. After the professional women suffers the reproductive health, mainly for menstrual disorders, pregnancy induced hypertension, premature menopause, declining fertility, spontaneous abortion, low birth weight, congenital malformations or even fetal death.
Third, the strongest part of computer radiation is on the back, followed by left and right sides, but the front of the screen has the weakest radiation. So, try not to go to the back of the computer, the distance is best that you can clearly see the words, and at least a distance of 50 cm to 75 cm, thus reducing the harm of electromagnetic radiation.
