Also with the heat there is the humidity. I am fine with heat but not the humidity.
I used to work in one!!!!!! I cant imagine it nowadays.
I think it will have to be trial and error but will you have someone with you who could help if it does zap you?
I'm just thinking of the getting dressed afterwards as the changing rooms are likely to be warm/humid aswell.
If not go in something easy to be on the safe side...but it could well be you come out of it hugely relieved and waiting to do it again.
Please think of me when you slide into warm relaxing water as I am trying the opposite and will be squealing my way into the sea at Cornwall!!!
I wish you well.
