If used correctly, mouse pads with wrist rests can indeed alleviate wrist fatigue to a certain extent, which depends on the design of the mouse pad and usage habits.
The principle is: When the wrist is suspended for a long time or excessively flexed (such as using the mouse while leaning on the table), the muscles and ligaments of the wrist will remain tense and sore for a long time. The wrist rest supports the wrist, naturally maintaining the natural horizontal state of the wrist and forearm, reducing the pressure on the wrist, and thus playing a role in dispersing fatigue. However, if the wrist rest is too high, too hard, or improperly positioned, it may instead exacerbate discomfort.
