German spa culture requires nudity in the saunas. No underwear, no swimsuits. Just your skin and whatever hair and tattoos you might have on it. A towel is required to lay on the sauna benches, but wearing anything else is strictly verboten. When it comes to this particular brand of self-care, part of the adventure is letting go… of everything. But for an expat like me, who has certain hang-ups about their body, this can prove highly challenging.
