Top Bench or Bottom? How to Sit in a Sauna

The benches

The top bench is the hot one, and it is where the steam from a pour lands first and hardest. It is for the middle of a session, once you are warmed up, and for people who already know what they are doing in there.

The lower bench runs meaningfully cooler. It is where to start, and more importantly it is where to go when you think you are done. Most people who leave the room could have taken another ten minutes one level down.

The foot bench exists so your feet are not sitting in the coldest air available. In a well-built sauna your feet rest at roughly bench height rather than on the floor. If the room has one, use it. If it doesn't, sit cross-legged.

Lying down, where the room allows it and you are not taking up space other people need, puts your whole body in a single layer. It is the most even heating available and almost nobody does it.

How to run a session

Start low. Move up as you adjust. The instinct to walk in and climb straight to the top bench is the same instinct that makes people start a run too fast.

Rounds of ten to twenty minutes, with a cool-down between each. Two or three rounds is a session. Longer is not better and the Finnish position on competitive endurance in a sauna is that it is both silly and unhealthy.

When it gets to be too much, move down a bench before you move out the door. This is the single most useful habit in this article. The urge to leave the room is almost always an urge to leave the layer, and the layer is one step away.

The details nobody mentions

Get your feet up. Feet on a cold floor while your head is at 190°F is the most common reason people say they don't like saunas, and it is a seating problem rather than a sauna problem.

Sit on your towel, both for hygiene and because wood at 170°F against bare skin is unpleasant in a way you will remember.

And if your ears hurt before the rest of you has had enough, that is the stratification problem doing exactly what it does. It is also the one item on this list you can solve with equipment rather than with technique, which is why the wool felt hat exists.

Sharing a room with other people

Most of the above assumes you have the place to yourself. Usually you don't.
The top bench is the contested real estate, so if it is full and you are new, take a lower one. You will be more comfortable there anyway.

Leave a gap. A sauna bench is not a subway bench and the social spacing is wider than you would think, because everyone in there is radiating heat at everyone else.

If you are going to pour, say something first. Someone on the top bench is always ready for more and someone near the door is always at their limit, and a pour you didn't announce is the one thing that reliably annoys people in a shared sauna.

And if you are in there with someone who is clearly having a hard time, the kind thing is to not make a thing of it. People leave rooms. It is fine.

Reading a room you have never been in

You can tell most of what you need in the first thirty seconds.

Look at the stove. Stones on top means you can pour. No stones means you can't, and if there are panels rather than a stove you are in an infrared cabin and most of this article does not apply.

Look at the benches. Two levels or more is a good sign. One level, or a single bench with nothing for your feet, tells you the room will heat you unevenly and that you should plan on shorter rounds.

Look at the ceiling height. Low ceiling with the top bench close to it means the gradient is compressed and the top bench will be hotter than the thermometer suggests.

Then find the thermometer, note what it says, and ignore it. It is usually mounted at the wrong height to describe where you are actually sitting.

When the room itself is the problem

Sometimes there is no seating strategy, because the room is built wrong.

A 7-foot ceiling with the benches dropped to fit under it. No foot bench. A stove sized for a space twice as big, or half as big. Ventilation that was never thought about.

If the gap between your feet and your head is 85 degrees, no amount of moving around fixes it. You are in a room that heats you unevenly by design, and the honest advice is to sit lower, keep the rounds shorter, and find a better sauna when you can.

Our own sauna went into an existing space with an odd shape, and the heater ended up in a nook off to one side. That is not where you would put it if you were drawing the room from scratch.

What fixed it was a mechanical exhaust at the back. Fresh air gets pulled in low near the heater, warms immediately, and rises, so the room turns over instead of settling. We did not get rid of the gradient, and you wouldn’t want to. We got it down to something closer to the Finnish target, where your feet and your head are in the same session.
