I have issues with showering and washing my hair. It is both the heat and the holding my arms above my head. I have a shower chair and take very quick lukewarm showers. I wash my hair twice a week. I make sure it is about 1 hr after mestinon so I am the strongest. I wash my hair in the shower on a bath chair with lukewarm water. Even so I am short of breathe for an hour or more after washing my hair and very fatiqued. I have not figured out a way to ease this process anymore. Sorry you are having the same issue.

Someone suggested to me that I should have my teenage daughter help me by washing my hair in the sink with the sink hose. I never laughed so hard. My teenage daughter help me!!! I am still chuckling.

good luck
