Löyly: The Word That Explains Finnish Sauna

The vocabulary to know

kiuas is the stove, and more specifically the stones on top of it. The stones are the part that matters, because they are what holds the heat and turns the water into steam.

lauteet are the benches. Plural, because a sauna is supposed to have more than one level.

löylyn heitto is the act of throwing the water. Literally the throwing of löyly.

kiulu is the bucket and kauha is the ladle.

vihta is the bundle of birch branches used for whisking, in western Finland. In the east the same thing is a vasta. Finns find the regional split funny in roughly the way Americans find pop and soda funny.

laudeliina is the small cloth you sit on. A culture that has a dedicated word for the bench towel is a culture that has thought about the bench towel.

saunoa is a verb. To sauna. English makes you say "take a sauna" or "have a sauna," both of which sound like you are stealing furniture.

jäähy is the cooling break between rounds.

avanto is the hole cut in lake ice for winter swimming, which is what the cooling break looks like in February.

savusauna is the smoke sauna: no chimney, heated for hours, smoke let out before you go in. Most Finns will tell you it is the best version of the thing, and they are right.

saunatonttu is the sauna elf, who lives in the sauna and disapproves of people misbehaving in it.

saunahattu is the sauna hat. Which brings us to a detail we find genuinely funny.

The part where the hat turns out not to be Finnish

Finnish sauna glossaries do list saunahattu. They also tend to note, in the same breath, that it is not very common in Finland.

The felt hat is overwhelmingly a Russian banya and Baltic tradition, and the reason is temperature. A banya steam room routinely runs above 200°F, at or above the hottest end of the Finnish range, and the hotter the room the sooner your head becomes the thing that ends the session.

We wrote about that in more detail elsewhere. It is mentioned here because a glossary is exactly the sort of page where you find out that the thing everyone assumes is Finnish is not.

A few more worth knowing

sauna itself is the only Finnish word in common English use, which is a slightly remarkable fact. There are roughly a dozen Finnish loanwords in English and this is the one everybody knows.

palju is the hot tub, usually wood-fired, usually outdoors, usually next to the sauna.

rantasauna is a lakeside sauna, the version in every photograph of Finland you have ever seen.

saunapäivä is sauna day. Traditionally Saturday. A recurring appointment rather than something you do when you feel like it, which is probably the single biggest difference between how Finns use a sauna and how Americans do.

Why any of this matters

A culture builds precise words for the things it takes seriously. Finnish has a dozen words covering parts of an experience that English handles with "sitting in the hot room."

That is not an argument that Finns are doing it right and you are doing it wrong. It is an argument that there is more going on in there than a temperature reading, and that having words for it makes it easier to notice.
