What to wear
Or not wear, as the case may be...
Don’t: be nervous about being naked
No one at a nude sauna is looking at your body—seriously. Scott adds that it’s important to remember that sense of comfort and liberation you can feel from shedding your clothes is proportional to the comfort you allow others. Don't stare—there's nothing you haven't seen before, and there are too few spaces in the world where we can feel free of shame and judgment.
Nudity might not be expected, anyway. Every sauna is different, so to maximize steam room etiquette, take a peek at what others are doing and follow suit (or birthday suit, as the case may be).
Do: grab a sauna towel
Even if you're nude, you should have a towel on hand for sanitary sitting. Expect some pronounced frowns if you come in wearing street clothes or athletic wear (or, especially, shoes), which bring outside cooties into the warm, humid haven.
Don't: even think about swimsuits
First, the man-made textiles trap heat and moisture, negating that pore-opening catharsis so many crave. Second, no one wants to relax in a cloud of atomized chlorine. And third, the moist heat can actually leach dyes from the suit, leading to some party-colored pores.
Do: take a shower
The number one best thing you can wear in a sauna is clean, freshly sudsed skin. Some places, such as King Spa, enforce this rule with shower-supervising attendants, and with signs that encourage you to snitch on soap-skipping guests. Other saunas expect guests already know the score.
Don’t: wear metal jewelry or hooks
Ouch.
