At present, the negative impacts of computers on human physiology and psychology have increasingly drawn people's attention. Therefore, it is extremely necessary to use computers scientifically and reduce the harm caused by computers and the Internet. First, it is necessary to enhance self-health care awareness: Pay attention to taking appropriate breaks during work. Generally speaking, computer workers should take a break of about 10 minutes after working continuously for one hour. And it's best to go outside the studio to stretch your hands, feet and torso. One should strengthen physical exercise in daily life to enhance physical fitness, and have regular physical check-ups and self-psychological tests. Second, pay attention to the working environment: The lighting in the computer room should be appropriate, neither too bright nor too dim. Avoid direct light shining on the screen to prevent interference. The studio should be kept well-ventilated and dry to allow harmful gases to be discharged as soon as possible. Try to use non-impact printers to reduce noise. Thirdly, pay attention to the correct operating posture: The center of the computer screen should be installed at the same level as the operator's chest. It is best to use a chair that can be adjusted in height. When sitting, there should be enough space to stretch your feet. Do not cross your feet to avoid affecting blood circulation. Fourth, pay attention to protecting your eyesight: Avoid operating the computer continuously for a long time and take breaks in between. To maintain the most appropriate posture, the distance between the eyes and the screen should be 40 to 50 centimeters, with both eyes looking straight ahead or slightly downward at the screen. This can relax the neck muscles and minimize the exposed area of the eyeball. If you experience dry, red eyes, a burning sensation or a foreign body sensation, heavy eyelids, blurred vision, or even eye pain or headache, it is necessary to see an ophthalmologist at a hospital. Fifth, pay attention to supplementing nutrition: Computer workers who spend too much time in front of the screen will consume the rhodopsin on the retina, and rhodopsin is mainly synthesized from vitamin A. Therefore, computer workers should consume more carrots, Chinese cabbage, bean sprouts, tofu, red dates, oranges, as well as milk, eggs, animal livers, lean meat and other foods to supplement vitamin A and protein in the human body. Drinking more tea, as the active substances such as tea polyphenols in tea can help absorb and resist radioactive substances. Sixth, pay attention to keeping the skin clean: There is a large amount of static electricity on the surface of the computer screen. The dust accumulated on it can be transferred to the exposed skin areas of the face and hands. Over time, it is easy to cause rashes, pigmentation, and in severe cases, even skin lesions.
