Why does my arm get tired while brushing my teeth?

When you brush your teeth, your arm might feel tired because of how often you use it or if there are any health conditions affecting you.

Possible Reasons:

1. Reduced Arm Use: Sometimes, people don’t use their arms as much as they could during the day. This can make the muscles weaker, so they get tired more easily when you do simple tasks, like brushing your teeth.
2. Fatigue from Health Conditions: Certain health conditions, like early-stage Parkinson's disease, can make you feel tired even after small activities. This is called post-exertional malaise, where your body feels more tired than usual after doing something.

What You Can Do:

• Keep Moving: Try to use your arms more during the day with light exercises or activities to help build strength.
• Talk to a Doctor: If your arm keeps getting tired, it might be good to see a doctor to check if there is a health condition that needs attention.
