The problems you probably have is because you're used to an unnatural, skin damaging shower routine with lots of hot water and products that strip you of your oils so your already stripped and vulnerable skin can't handle the salt.
What you should do is stop washing yourself in advance, or just shower as little as possible with lukewarm water and don't use any soap or shampoo or other products.
Bathing is a meme anyway, it's a cultural thing with no real use. There's the exception of hands washing and such in certain circumstances, but generally you don't need to shower for health reasons and most people wash and groom to a degree that is detrimental to their overall health.
Become a greasy cunt and you will have no discomfort.
