Sauna etiquette: a first-timer's guide

Almost nobody's first sauna is relaxing, because they spend it quietly worried they're doing it wrong. Here's the reassuring truth: sauna etiquette is mostly common courtesy plus a handful of specifics, and everyone in that room was once exactly as unsure as you. Learn the few rules that matter and you can stop thinking about them — which is the entire point.

It depends where you are, and this is the question that makes people most nervous — needlessly. In a public spa or gym, swimwear is normal and expected. In much of Finland and in traditional saunas, single-sex saunas are usually enjoyed nude, with a towel to sit on. Mixed public saunas vary, so when in doubt, wear swimwear and follow the room.

The one rule everywhere: always sit on a towel. It's hygienic, it's polite, and it's the one lapse a room will quietly hold against you. Bring one to sit on and one to dry off with.

Start with 10–15 minutes, sit on a lower bench where it's cooler, and leave before you feel you have to. Then cool down — a shower, fresh air, or a cold plunge — rest, and go back for another round if you like. Two or three rounds is a full, satisfying session.

Listen to your body over any clock. Lightheaded, pounding, or just done? Step out. The sauna will still be there. (Our beginner's contrast ritual walks through the whole hot-cold-rest rhythm.)

None of these are hard, and most are just kindness in a hot room:

That burst of steam when water hits the hot stones has a name — löyly — and it's the heart of the whole thing. It's also communal: a ladle or two lifts the humidity and the heat for everyone in the room, so it's polite to ask first, add gently, and never drown the stones. If you're curious about the word (and the rest of the sauna's small vocabulary), we wrote a short glossary.

Nobody is watching you. Everyone is turning red — that's just blood doing its job. You can leave and come back as many times as you like. You don't need special breathing or a routine. Sweating a lot isn't a competition, and neither is enduring the top bench. A sauna is one of the few genuinely un-performative places left; the only way to do it wrong is to make it stressful.

Two towels, plenty of water before and after, and — once you're doing multiple rounds — a wool sauna hat, which keeps your head cool so you can stay in comfortably instead of tapping out early. That's the difference between one hot minute and a proper, unhurried session.

Everything above, if you're heading in now:

Arrive clean, sit on a towel, be quiet and kind, and listen to your body. That's 95% of sauna etiquette, and the other 5% you'll pick up by osmosis. Bring water and a hat and your first proper session will feel less like an exam and more like the point.
