There is a correct sequence for this, and most people get one step wrong before they even sit down.
You shower before going in. Almost everyone knows that part. What almost nobody is told is that you then dry yourself off completely, and skipping that single step makes the whole session work worse.
Dry off before you go in
Wet skin cannot sweat properly.
Sweating is your body’s cooling system, and it works by evaporation. If you walk into a sauna with water already sitting on your skin, that water evaporates first. Your body reads the cooling and delays producing its own sweat. You sit there feeling hot, dripping, and wondering why nothing is happening, because what is running off you is shower water rather than sweat.
Towel off properly and your body starts sweating on its own schedule, which is the point of being in there.
So the sequence is: shower with soap, rinse, then dry completely, then enter. The shower is about hygiene, which matters in a shared room. The drying is about physiology.
What to do before you go in
Drink a glass of water twenty to thirty minutes ahead. Not a liter, and not immediately before, since a full stomach of cold water is uncomfortable in heat.
Eat something light an hour or two ahead. A heavy meal and high heat do not combine well, and neither does an empty stomach if you are prone to feeling faint.
Do not drink alcohol. This is the single most important rule in sauna use, and it is not a formality. The Finnish research on sauna-related deaths found alcohol to be a major contributing factor in most of them. It impairs your temperature regulation and it removes the judgment you need to decide when to get out.
Take off jewelry and remove your watch. Metal conducts heat and gets uncomfortably hot against skin. Glasses fog immediately and contact lenses can dry out, so most regulars take both off.
There is a longer guide on what to wear to a sauna, but the short version is a towel, and you sit on it rather than directly on the wood.
Your first session
Sit on a lower bench. This is the part first-timers most often get wrong in the other direction, by climbing straight to the top because that is where everyone else is.
A sauna has a temperature gradient rather than a temperature, and the difference between the top bench and the bottom one can be thirty degrees Celsius. The lower bench is a genuinely different room. Start there.
Five to ten minutes is a complete first session. There is nothing to prove by lasting longer, and acclimation takes weeks rather than one heroic sit. The full guidance on how long to stay in a sauna is worth reading once you have done a few, but for a first visit, short is correct.
Sit or lie down rather than standing. Standing puts your head in the hottest air in the room, which is the fastest route to feeling lightheaded.
Breathe through your nose. It warms and humidifies the air on the way in, which is easier on your throat than mouth breathing in dry heat.
Get out when your body says to, not when the clock does. Lightheadedness, a racing heart, nausea, a headache, or the heat turning from pleasant into something you are enduring are all signals to leave. That last one usually comes first and is easy to talk yourself out of.
Between rounds
Finnish practice is not one long sit. It is rounds, with a cool-down between each one, and the cool-down is part of the session rather than a break from it.
Step outside or take a cool shower. Let your heart rate settle and your skin stop feeling hot to the touch, which usually takes about as long as the round itself did. Drink water during this window rather than inside the sauna.
If there is a cold plunge, this is where it fits. There is separate guidance on cold plunge temperature and duration, and it is worth reading before your first one rather than after.
Then go back in for a second round if you feel like it. Two or three rounds is a normal session. One is completely fine for a first visit.
The wet or dry question, answered properly
This comes up constantly and the answer has two halves that get confused with each other.
You go in dry. Skin dry, hair reasonably dry, having showered and towelled off. That is the physiological part, covered above.
The room itself can be dry or wet, and that is a separate thing entirely. A traditional Finnish sauna is a dry room until someone ladles water on the rocks, at which point it briefly becomes a wet one. Both are normal. A steam room is a permanently wet room and a different format again.
So when someone asks if a sauna is wet or dry, the honest answer is that you arrive dry and the room can be either, depending on what is happening with the rocks.
Drinking water inside the room
Traditional practice says no, and there are practical reasons for it.
Drinking cold water in a hot room can cause stomach cramps. Plastic bottles do not belong in that heat. And carrying a bottle in and out disrupts the rhythm of the session for you and for anyone else in the room.
Drink before, drink between rounds, and drink properly afterward. If you find you cannot last a round without water, the round is too long or the bench is too high.
Phones and other things people bring in
Leave the phone outside. Heat damages batteries and screens, and there is a separate answer on what happens to a phone in a sauna if you want the detail. Beyond the hardware, most sauna rooms have an unspoken rule about screens, and it is a room people go into to be away from them.
The same goes for books, which warp, and headphones, which do not enjoy the environment either.
One more thing that catches people out. A sauna heats up long before the benches and walls do. If a session is booked for a specific time, arriving into a room that has only just reached temperature feels different from one that has been running for an hour, because the surfaces are still cool and the heat has not settled. This matters mostly for home and rented units rather than gym saunas, which run continuously.
Afterward
Cool down before you get dressed. Putting clothes on while still sweating is uncomfortable and you will keep sweating into them for twenty minutes.
Stand up slowly. Blood pressure often drops right after a session, and the dizzy moment when standing is common and avoidable.
Rehydrate with something containing sodium after a long session rather than water alone, since sweat takes electrolytes out along with the fluid.
Do not drive immediately if you feel at all lightheaded. Give it fifteen minutes.
What to skip on your first visit
Do not ladle water onto the rocks unless you understand what it does. It barely moves the thermometer and it sharply raises how hot the room feels. Let someone experienced handle it, and if you are alone, leave it until you have a few sessions behind you. Sauna temperature is more complicated than the dial suggests.
Do not try to match the person who has been going for ten years. Acclimation is real and physical, and there is no shortcut through it.
Do not go if you are unwell, hungover, or have been drinking. The hangover case is the one people ignore most and it is a genuinely bad idea, since you are already dehydrated.
If you have a heart condition, blood pressure issue, are pregnant, or take medication that affects temperature regulation or blood pressure, read who should avoid the sauna before your first session and speak to a doctor.
Building from here
After a few sessions, the room stops feeling like an endurance test and starts feeling like something else. That usually takes two or three weeks of regular use.
At that point, how often you go matters more than what happens in any single session, and the sauna etiquette that regulars follow starts to make sense from the inside rather than reading like a list of rules.
If your first sauna is a rented one at home rather than a gym, knowing what to expect from a session covers the parts that are different, mostly around setup, heating time, and having the space to yourself.
The bottom line
Shower, dry off completely, sit low, stay five to ten minutes, cool down properly, and go back in if you want to.
Leave the phone, the alcohol, and the ambition outside. The first session is about finding out how your body responds, and there is no version of this where doing more of it faster works better.
