1. 手腕姿势:使用鼠标时,手腕应保持自然放松的状态,避免过度弯曲或扭曲。

This can not only improve work efficiency but also reduce hand, shoulder, and neck fatigue and injuries. Here are some suggestions on the correct usage of computers and mice:
First, computer placement and usage:
1. Chair height: The height of the chair should allow the feet to rest flat on the ground, with the thighs parallel to the ground. 2. Screen height: The center of the screen should be at eye level, avoiding long-term neck bending or lifting. 3. Keyboard placement: The keyboard should be placed directly in front of the body, about an arm's length away, so as to avoid excessive arm stretching or twisting. Second, correct mouse usage: 1. Wrist posture: When using the mouse, the wrist should remain in a natural and relaxed state, avoiding excessive bending or twisting. 2. Sitting posture: Sit upright with both shoulders relaxed, avoiding long-term slouching or twisting of the body. 3. Finger placement: Fingers should rest on the mouse without applying excessive pressure, so that they can move or click more easily and freely when needed. Third, avoiding prolonged continuous operation: It is necessary to take breaks periodically when using computers or mice to avoid prolonged continuous operation. Take a break every so often to stand up and walk or do some simple stretching exercises to relieve muscle fatigue.
