Why are my hands tired and what can I do to relieve the fatigue?

Your hands may be tired due to overuse or strain from activities like typing, writing, or gripping objects for a long time. To relieve the fatigue, you can try stretching exercises, taking breaks to rest your hands, using ergonomic tools, applying heat or cold packs, and practicing good posture. If the fatigue persists, it's important to consult a healthcare professional for further evaluation and advice.
