Is there such a thing as taking too hot of a shower?

My significant other takes what almost seems to be scalding hot showers, and her skin is shockingly red all over when she's done. She's got that Australian type of skin, you know, a bit weathered, though I'm not sure if it's related, as she also spent a fair amount of time outdoors in previous years. It just doesn't seem right to look burnt after taking a shower, but I find no evidence that there's anything wrong with it either, strangely enough, just a bunch of silly responses.
