What might cause my arms to get tired when washing my hair?

Your arms might get tired when washing your hair due to conditions like generalized myasthenia gravis, which causes muscle weakness, or issues with your arm and shoulder, potentially made worse by sleep problems.

Explanation

Feeling tired in your arms while washing your hair can happen for a few reasons. One possible cause is a condition called generalized myasthenia gravis. This condition makes muscles weak, especially after using them for a while, like when you lift your arms to wash your hair. People with this condition find that everyday tasks can be more tiring than usual.

Another reason could be related to problems with your arm and shoulder. If you have difficulties or pain in these areas, it can make it hard to do tasks that involve lifting your arms. Sometimes, not sleeping well can make these problems worse. Poor sleep can affect how you feel during the day, making your muscles feel tired more quickly.

If you notice that your arms are getting tired often, it might be helpful to talk to a healthcare professional who can provide more detailed guidance and support.
