I know. What will it be like to play computer for a long time?

First, it has a direct impact on health: computer monitors are accompanied by radiation and electromagnetic waves. Long-term use will harm people's eyes and induce some eye diseases, such as glaucoma. Pressing keys for a long time will be bad for fingers and upper limbs; When operating a computer, the body shape and whole body rarely change. High-speed, single, repetitive operation and persistent forced posture can easily lead to diseases of musculoskeletal system. The main parts involved in computer operation are waist, neck, shoulders, elbows and wrists.

The second is the harm of computer microwave to the body: the low-energy X-rays and low-frequency electromagnetic radiation of computers are easy to cause the disorder of people's central nervous system. An office electromagnetic wave study in Britain confirmed that the low-frequency radiation and magnetic field emitted by computer screens can cause 765,438+09 diseases, including itchy eyes, neck and back pain, short-term memory loss, irritability and depression. For women, it is easy to cause abnormal reproductive function and embryonic development, dysmenorrhea, prolonged menstruation and other symptoms. A few women also have premature delivery or miscarriage. Pregnant women use computers for more than 20 hours a week, and the incidence of abortion increases by more than 80%. At the same time, it can also lead to fetal malformation.

Third, increase mental and psychological stress: in the process of operating the computer, attention is highly concentrated, eyes and fingers move quickly and frequently, which makes the physical and psychological burden too heavy, thus causing drowsiness, neurasthenia, head pain, decreased immunity, and even inducing some mental diseases. This kind of person is easy to lose self-confidence, often nervous, irritable and anxious, which eventually leads to

Cause physical and mental fatigue.

Fourth, it leads to network syndrome: spending a lot of time and energy chatting and browsing online for a long time will lead to various behavioral abnormalities, psychological disorders, personality disorders and partial dysfunction of sympathetic nerve function. In severe cases, it will develop into network syndrome. The typical manifestations of this disease are: depression, loss of interest, sleep disorder, disorder of biological clock, loss of appetite, weight loss, listlessness, mental retardation and excitement, low self-evaluation and thinking.

5. Gases emitted by computers are harmful to the respiratory system: computers, laser printers and other equipment will release ozone harmful to human health, which is not only toxic, but also causes some people to have difficulty breathing, especially those with asthma and allergies. In addition, staying in places with high ozone concentration for a long time can also lead to lung diseases.
