Prevention methods:

Develop good working posture and habits: adjust your working posture, such as the operating posture and sitting posture of keyboard and mouse. When operating the computer, try to relax your upper body, lay your feet flat on the ground naturally, and your knees are at an angle of about 90 degrees. Don't move your arm too much. Don't lean your wrist on the keyboard or desk for a long time when typing or resting, so as not to overload your wrist. It is best to use seats with adjustable height, especially upholstered seats. The backrest and armrest are indispensable, and the waist protector can be placed behind the back to prevent the spine from being pressed by bending forward. In addition, the height of the keyboard should be 60 to 70 cm. Don't push your fingers too hard when typing, keep your elbows parallel to the keyboard, and keep your wrists and elbows in a straight line as far as possible. The height and distance between the eyes and the screen should be appropriate. The eyes should be the same height as the top edge of the screen, about 35 to 70 cm away from the screen. It's best to rest after working for one or two hours at a time 10 to 15 minutes. Don't stare at the screen for a long time to avoid hurting your eyes.

Use ergonomic peripherals: For people who use computers for a long time, it is best to design tools around the computer according to ergonomics, otherwise long-term use will lead to physical injury. The screen is equipped with goggles, so we should consider reducing glare, reflection, electromagnetic waves and static electricity. The keyboard and mouse should conform to ergonomics in key position arrangement, hand position placement, grip feeling and other factors; When typing, it is best to use a typing clip and wrist rest to avoid neck, elbow and wrist injuries. With the adjustable algebraic tables and chairs, the height, sitting posture and working posture can be adjusted according to the appropriate position of human height. Try to use light bulbs close to natural light and avoid flickering, too strong or too weak light.

◆ Regular physical examination to ensure good health: People who have been engaged in computer work for a long time should have a basic physical examination every six months, and they should be alert to their physical condition at ordinary times. If there are abnormal symptoms, you should seek medical attention in time to prevent the illness from becoming an incurable disease due to delay.
