Could You Survive a Finnish Sauna?
The heat is the part everyone warns you about, and the part that matters least. Six lines from a real Finnish sauna - top bench, or still by the door?
A Finnish sauna is not a heat-tolerance test. The heat is adjusted to the people in the room, and most of what gets said in there is a question you are expected to answer.
Everyone warns you about the heat. Nobody warns you about the conversation.
Six things said in a sauna, in the form they are actually said.
Most visitors think the sauna is a heat-tolerance test. It is mostly a listening test.
Somebody by the stove has the ladle in their hand. They look over at you.
“Heitetääks lisää?”
Heittää löylyä is the usual verb for throwing water on the stones; lyödä löylyä is the older alternative and still heard. The form here is the passive with the question ending worn down - heitetäänkö becomes heitetääks - and in speech the passive means we.
You said yes. Three throws later the air has a weight to it, and they glance round.
“Riittääkö?”
There is no endurance contest here, which is the most useful thing a visitor can be told. The heat gets adjusted to the people in the room, and saying it is enough is ordinary sauna conversation rather than an admission of anything.
Your first week in a Finnish apartment building. A neighbour mentions this in the stairwell.
“Teillä on saunavuoro lauantaisin.”
Most Finnish apartment blocks have a shared sauna, and flats book a recurring private hour through the building company. It is your slot, alone or with whoever you bring, rather than a shared session with the neighbours.
Someone stands up and heads for the door, nodding at the birches in the yard.
“Mä haen vastat.”
Called vasta in the east and north and vihta in the west, with the line running roughly from Porvoo to Oulu. Asking somebody which word they use places where they grew up more reliably than almost any other question.
Somebody stands up, and on their way out says this over their shoulder.
“Mä käyn vilvottelemassa.”
The cooling-off trip has its own verb, and for a lot of Finns it is the better half: out into the cold air, or into the lake, and then back in. Sitting in the heat continuously is the beginner's version of this.
Afterwards, in the changing room. Somebody says this to nobody in particular.
“Kiitos saunasta.”
Said on the way out, to the room rather than to a host, and it is close to obligatory. The companion phrase is hyviä löylyjä, which you say to people going in as you are coming out.
0/6
Ylälauteilla
Top bench, where the heat actually is. Six out of six means you followed a room that runs almost entirely on short questions, and you caught the one that places a speaker geographically.
The thing worth reaching for next is the sauna's own small talk. Hyviä löylyjä on the way past someone going in, kiitos samoin back. Two phrases, and they are the difference between being in the room and being a guest in it.
0/6
Keskilauteilla
Middle bench, which is where most of the conversation happens anyway. The top is too hot to talk on and the bottom is too far from it.
What you lost was almost certainly the passive. Heitetääks and riittääkö are both addressed to the room, and both sound like they are addressed to nobody until you work out that the room is the we.
0/6
Alalauteilla
Bottom bench. It is the coolest seat in the room and nobody admits to choosing it on purpose.
The sauna runs on about eight words: löyly, kiuas, lauteet, vasta, vilvotella, riittää, saunavuoro. That is an afternoon's work, and it covers most of what gets said in there.
0/6
Oven suussa
By the door, which is where you sit when you are not sure you are staying.
Nothing in that quiz was difficult vocabulary. It was six short questions asked sideways, in a room where people say as little as they can get away with - and the fix is the sauna's own word list rather than more grammar.

What each one actually was
1 Heitetääks lisää?
Somebody by the stove has the ladle in their hand. They look over at you.
- Shall we throw more water on the stones? - correct answer
- Yes, and it is a question to the room rather than to you specifically. Anyone near their limit is expected to say so now rather than quietly endure it.
- Should I put more wood in?
- Different job, different verb. Tending the fire is laittaa puita, and in an electric sauna it does not arise at all.
- Shall we go again later?
- You have read lisää as another round rather than as more water. It is more of the thing happening right now.
Why it works Heittää löylyä is the usual verb for throwing water on the stones; lyödä löylyä is the older alternative and still heard. The form here is the passive with the question ending worn down - heitetäänkö becomes heitetääks - and in speech the passive means we.
2 Riittääkö?
You said yes. Three throws later the air has a weight to it, and they glance round.
- Is that enough? - correct answer
- Right. Riittää is to suffice, so this is a genuine check, and joo, riittää is a completely normal answer.
- Is it hot enough yet?
- The opposite direction. That would be onks tarpeeks kuuma? This one is asking whether to stop.
- Can you handle it?
- Nothing in the word is about you or your limits. That reading is imported - it is the sauna-as-a-dare idea, and the room is not thinking it.
Why it works There is no endurance contest here, which is the most useful thing a visitor can be told. The heat gets adjusted to the people in the room, and saying it is enough is ordinary sauna conversation rather than an admission of anything.
3 Teillä on saunavuoro lauantaisin.
Your first week in a Finnish apartment building. A neighbour mentions this in the stairwell.
- Your flat has a sauna slot on Saturdays. - correct answer
- Correct, and it is worth using: the slot is attached to the flat rather than to you, and it is billed as a separate few euros a month whether you turn up or not.
- The sauna is open to everyone on Saturdays.
- Teillä is you have, and it is doing the important work. The hour belongs to your flat.
- It is your turn to clean the sauna on Saturday.
- A fair guess from vuoro meaning a turn, but the turn here is a turn to use it. Cleaning is the building's job.
Why it works Most Finnish apartment blocks have a shared sauna, and flats book a recurring private hour through the building company. It is your slot, alone or with whoever you bring, rather than a shared session with the neighbours.
4 Mä haen vastat.
Someone stands up and heads for the door, nodding at the birches in the yard.
- I'll go and get the birch whisks. - correct answer
- Yes. You hit yourself with it, gently, and it is neither a joke nor a punishment - the leaves smell of the forest and it moves the heat around on your skin.
- I'll go and get the towels.
- Reasonable, and wrong. Towels are pyyhkeet, and they would not be growing in the yard.
- I'll go and get the firewood.
- Firewood is puut or klapit. The nod at the birches is the clue, but it is the leaves that are wanted, not the trunk.
Why it works Called vasta in the east and north and vihta in the west, with the line running roughly from Porvoo to Oulu. Asking somebody which word they use places where they grew up more reliably than almost any other question.
5 Mä käyn vilvottelemassa.
Somebody stands up, and on their way out says this over their shoulder.
- I'm going to cool off. - correct answer
- Right, and it is not the end of the session. They will be back - heat, cold, sitting outside, repeat is the shape the whole evening takes.
- I'm going to wash.
- That would be käyn pesulla. Washing happens in a sauna, but it is not what this verb is about.
- I'm heading off, thanks.
- Too final. Käydä is to go somewhere briefly and come back, which is the entire point of the trip.
Why it works The cooling-off trip has its own verb, and for a lot of Finns it is the better half: out into the cold air, or into the lake, and then back in. Sitting in the heat continuously is the beginner's version of this.
6 Kiitos saunasta.
Afterwards, in the changing room. Somebody says this to nobody in particular.
- Thanks for the sauna. - correct answer
- Yes, and the reply is usually kiitos samoin or nothing at all. It is said to whoever shared it with you, not to whoever heated it.
- Thanks, the sauna is free now.
- Nothing here is about availability. The -sta ending is for the sauna, not about its state.
- Thanks, but I won't go in.
- The opposite of the situation. This is said by somebody who has just come out.
Why it works Said on the way out, to the room rather than to a host, and it is close to obligatory. The companion phrase is hyviä löylyjä, which you say to people going in as you are coming out.

About this quiz
The heat is the part everybody warns you about and the part that matters least. A Finnish sauna is a room where people say very little, ask each other short practical questions, and get up and go outside at intervals that look random until you know what the words mean.
Six lines here, all ordinary. The passive standing in for we in heitetääks lisää, the check that is genuinely a check in riittääkö, the building-management vocabulary hiding in saunavuoro, the east-west split between vasta and vihta, the verb for the cooling-off trip, and the thing you say on the way out.
Get these and the room stops being a test of how long you can sit still. That is worth more than another twenty degrees.

Questions people ask
How hot is a Finnish sauna?
Usually 80 to 100°C on the upper bench in a normal sauna, and lower in a smoke sauna, around 60 to 80°C, where the heat feels softer because the humidity is higher. The number matters less than the löyly - the burst of steam off the stones.
What do you actually say in a Finnish sauna?
Less than you would expect, and most of it practical. Heitetääks lisää for more steam, riittää when it is enough, kiitos saunasta on the way out. Long stretches of nothing in between, and that is not awkward.
Is it rude to leave a Finnish sauna early?
No. People come and go through the whole session, because the cycle of heat and cooling off is the normal way to do it. Käyn vilvottelemassa announces exactly that, and nobody hears it as leaving.
What is a saunavuoro and does it cost extra?
It is a booked weekly hour in an apartment building's shared sauna, attached to your flat rather than to you. It is normally billed separately from the maintenance charge, a few euros a month, which means many residents pay for a sauna they never book.
What is the difference between vasta and vihta?
Nothing, except where you are standing. Both are the bundle of birch twigs used in a sauna - vasta in the east and north, vihta in the west, with the line running roughly Porvoo to Oulu.
Do you have to be naked in a Finnish sauna?
In a private sauna or a gender-separated one, usually yes, and it is not treated as significant. Swimwear belongs to spas and mixed public saunas; a hotel sauna is normally separated by gender and naked like any other.
