Hi Sarah
I really have no idea as to whether the experience would be unpleasant as a result of sweating.
Sweating dehydrates and rids the body of electrolytes. So both do need replenishment. The answer to your question is probably quite complex with convoluted biochemical considerations to be taken into account.
Of course I wonder whether there is a good reason for you to go to the solarium!
Namaste
