According to research results
no matter what kind of radiation, under normal operating conditions, the intensity enough to cause harm to humans.
Recommendations and measures: Although computer-generated radiation insufficient to cause harm to humans, but in the selection of the computer, it is best to buy low radiation monitor, in addition to reducing radiation(
ibm thinkpad t43 battery), but also can eliminate the psychological burden. The results show that the side is the back of the monitor and the strong radiation zone, the direction should be adjusted to avoid sitting on the side and back of the computer screen. When no need to use the computer, you can turn off the monitor.
Can pregnant women use the computer? Many data indicate that: the frequent use of computers and other women the same age, color, and socio-economic status compared with women without any convincing evidence that computer use may result in miscarriage or fetal deformity.
Recommendations and measures: still want to remind pregnant women, in the early months of pregnancy, access to computers should be minimized so as not to is in a period of fetal organ formation damage.
Work at the computer on the skin will be affected? The air will be beneficial to the body of the anion adsorption by static electricity on the screen surface, making the computer operator in the anion and cation imbalance in their environment, can lead to headaches, fatigue, respiratory diseases, facial rash, etc.; Sweden and Norway, the use of
ibm thinkpad r52 battery experts is likely to increase the skin has been related research, but is still unable to confirm the generation of skin inflammation associated with the use of computer-
Recommendations and measures: Although you can not prove the skin inflammation is directly related to the use of
lenovo 3000 c100 battery, however, focus on improving the working environment, the air flow, temperature and humidity control, and work to eliminate stress, is still necessary, but also to avoid unnecessary concerns.
Long-term use of computers to the human mind a negative impact? Long been engaged in computer-related occupations, rapid development in technology today, face many competitors, could cause tremendous work pressure, the pressure on traditional social completely different. This pressure may arise under the influence of the following phenomena: distractions to concentrate on work, unaware of time,> loss. Anxiety, depression, headache, nervousness; difficult to control emotions. This would have an adverse effect on people.
Recommendations and measures: In general, to relieve stress and nervous tension, the burden can be reduced vision, reduce local and other musculoskeletal diseases, while allowing the work environment as comfortable as possible, reasonable arrangements for the task, working time, attention to work and rest to relieve work pressure. The top five hazards to human computer first, the direct impact on health: computer monitor with radiation and electromagnetic waves, long-term use will hurt people's eyes, and induced a number of eye diseases such as glaucoma; long fingers and upper limbs would be detrimental keystrokes; operate a
toshiba satellite l300 battery, the changes in body shape and body are rare, high-speed, single, repeat the operation, lasting forced position, easily lead to musculoskeletal disorders. Computer operations involved when the main parts of a waist, neck, shoulder, elbow, wrist, and so on. Second, the harm to the body of microwave
toshiba pa3634u-1bas battery: computer of low energy x-ray and low-frequency electromagnetic radiation, easily lead people to central nervous system disorders. Office of electromagnetic waves, a British study confirmed that low-frequency radiation emitted computer screen with the magnetic field, will lead to 719 kinds of diseases, including itchy eyes, neck pain, short-term memory loss, irritability and depression. Women also easily lead to abnormal reproductive function and embryonic development, there dysmenorrhea, prolonged menstrual symptoms, few women have preterm birth or miscarriage, pregnant women, more than 20 hours per week using computers, the abortion rate increased by 80% or more, while still cause fetal malformations. Third is to increase the mental and psychological pressure: the process of operating the computer a high concentration of attention, eyes, fingers fast frequent campaign to physical, mental over-burden, resulting in sleep and more dreams, neurasthenia, head soreness, decreased immunity, even induce a number of mental illness. Such people easily lose self-confidence, inner often tension, irritability, anxiety, leading to mental and physical exhaustion. Fourth, causes the network syndrome: a long time to spend inordinate amount of time and energy continued to chat on the Internet, browsing, will lead to a variety of behavioral abnormalities, mental disorders, personality disorders
toshiba pa3356u-2bas battery, some of sympathetic nerve function disorders, developed into a serious network synthesis sign, a typical manifestation of the disease are: depression, loss of interest, sleep disorders, circadian clock disorder, loss of appetite and weight loss, energy, psychomotor retardation and agitation, decreased self-evaluation, thinking slow, reluctant to participate in social activities, little concern for others, alcohol and drug abuse. Fifth, the computer harm the respiratory system of the gas distribution: computers, laser printers and other equipment will release the ozone harmful to human health, not only toxic, but some people can cause breathing difficulties, for those with asthma and allergy sufferers, the situation is even more is serious. In addition, a longer time at the local high concentration of ozone gas, but also lead to lung lesions occur. How to prevent harm to human health
toshiba tecra m2 battery tech for humanity to enjoy at the same time, the harm to the operator who has been the focus gradually. People engaged in computer operations should be self-health awareness.
But the laptop ac adapter LED turns off and the battery stops charging after a few seconds.
