How to Use a Traditional Sauna: A Step-by-Step Guide

How do you use a traditional sauna? Heat the room to about 170 to 190°F, shower, sit for 8 to 15 minutes, step out to cool off and rest, then repeat for two to four rounds. This guide covers each step of a home session, how to pour water on the stones, how to plan rounds, and the mistakes that make first sessions feel harder than they should.

The short answer

To use a traditional sauna, preheat it for 30 to 60 minutes until the thermometer reads about 170 to 190°F. Drink a glass of water, take a quick warm shower, and dry off so you sweat sooner. Sit on a towel on the lower bench for your first round of 8 to 15 minutes, then move higher if you feel good. Once you feel ready to leave, step out and cool down with a cool shower, a cold plunge, or fresh air. Rest for 5 to 10 minutes, sip water, and go back in. Most people do two to four rounds in total. Add water to the hot stones in small ladles during later rounds to create steam, which the Finns call löyly. End with a final cool rinse, a longer rest, and more water. Leave right away if you feel dizzy, nauseated, or unwell, and ask your doctor first if you have a heart condition, blood pressure concerns, or are pregnant.

Before you start: what you need

A traditional sauna session asks for very little gear. Keep these within reach so you never have to leave mid-round to find something:

• Two towels. One to sit on (it protects the benches from sweat) and one for drying off.
• A water bottle. Plan on 16 to 32 ounces over a full session, more in summer.
• A sauna bucket and ladle. Fill the bucket with clean tap water for löyly.
• A timer or sauna clock. It is easy to lose track of time in the heat. A sand timer or wall clock outside the glass works well.
• A cool-down plan. A shower, a cold plunge, a garden hose, or just a chair outside the door.
• Optional: a wool or felt sauna hat to keep your head cooler, sandals for the walk outside, and a headrest or backrest.

Skip jewelry, glasses with metal frames, and your phone. Metal gets hot enough to burn skin at sauna temperatures, and heat can damage electronics.

How to use a traditional sauna, step by step

1. Preheat the room

An electric heater usually needs 30 to 45 minutes to bring a home sauna to 170 to 190°F. A wood-burning stove often takes 45 to 60 minutes or more, depending on the room size and the weather outside. Wait until the stones are fully hot, not just the air. Hot stones are what make good steam later. For target numbers by experience level, see our sauna temperature guide.

2. Hydrate and shower

Drink a glass of water 15 to 30 minutes before you go in. Then take a quick warm shower. Clean skin keeps the benches fresh, and warm, damp skin starts sweating sooner. Dry off before you sit down, because a dry body sweats more evenly than a wet one.

3. First round: 8 to 15 minutes, no water yet

Lay your towel down and start on the lower bench, where the air is cooler. Sit or lie still and breathe through your nose. Many people keep the first round dry so their body can adjust. Stay until you feel ready to leave, and not a minute longer. For most beginners that is 8 to 12 minutes. Experienced bathers often go 12 to 15. Harvard Health advises keeping individual sessions to about 15 to 20 minutes at most.

4. Cool down

Step out and cool your body. You have three common options:

• Cool or cold shower for 30 seconds to 2 minutes. The easiest choice for most homes.
• Cold plunge at roughly 45 to 60°F for 30 seconds to 3 minutes, if you are healthy and have cleared it with your doctor. Our guide to sauna and cold plunge rounds covers timing.
• Fresh air. Sitting outside in cool air is the gentlest method and a good one for first sessions.

5. Rest and sip water

Sit or lie down for 5 to 10 minutes. Let your heart rate settle and your skin return to normal color. Drink a few sips of water. This rest period is part of the routine, not a break from it. Skipping it is the most common reason people feel light-headed on round two.

6. Second and third rounds: add löyly

Go back in and move to the upper bench if you feel comfortable. Now try water on the stones. Pour one small ladle, about 2 to 4 ounces, onto the center of the stone pile and wait 30 seconds. A wave of heat rolls down from the ceiling a few seconds later. If you want more, add another ladle. Pour only on the stones, never on the heating elements or the control panel. Our sauna humidity guide explains why a little water makes the room feel so much hotter.

7. Finish and recover

After your last round, take a final cool shower, then rest for 10 to 20 minutes before you get dressed. Drink another 8 to 16 ounces of water. Many people notice they feel calm and a little sleepy, which is why evening sessions are popular. Switch the heater off, leave the door ajar, and open the vents so the wood can dry.

Sample session plans

Use these as starting points and adjust to how you feel. Times are estimates for healthy adults, not medical targets.

Ranges reflect common Finnish practice and published sauna research. A review in Mayo Clinic Proceedings describes typical Finnish sessions of about 5 to 20 minutes at 80 to 100°C (176 to 212°F) with low humidity.

How often should you use a traditional sauna?

Two to three sessions a week is a practical rhythm for most new home owners. The large Finnish cohort studies that link sauna use with heart health tracked people who used a sauna four to seven times a week, but they were long-time bathers. Build up slowly and let how you feel guide you. Our article on how often you should use a sauna breaks down the research by weekly frequency.

Common mistakes to avoid

• Going in dehydrated or after drinking. Harvard Health advises avoiding alcohol before and after a sauna because it raises the risk of low blood pressure, arrhythmia, and overheating.
• Staying too long to "earn" it. Longer is not better. Leave when your body tells you to.
• Dumping water on the stones. Too much at once creates a scalding blast of steam. Small ladles, spaced out.
• Standing up fast. Sit up for a moment before you stand, since blood pressure can drop as you leave the heat.
• Skipping the rest period. Rest is where your heart rate and temperature settle before the next round.
• Using the wrong water. Use plain tap water. Pool water, saltwater, or undiluted essential oils can damage stones and heaters.
• Leaving the room wet. Always vent the sauna after use so the wood dries and stays mold-free.

Traditional vs infrared: how the routine differs

If you have only used an infrared sauna, expect a traditional sauna to feel hotter and more intense, with shorter rounds. Infrared sessions often run a single 20 to 40 minute block at 120 to 150°F with no water and no cool-down rounds. Traditional sessions are built around heat and cool cycles. If you want both styles at home, a hybrid sauna lets you run dry infrared on busy days and a full löyly session on weekends. For more background on the Finnish style, read what a Finnish sauna is.

Who should be careful, and who should skip it

Traditional sauna use is well tolerated by most healthy adults, but it does raise heart rate and lower blood pressure. Talk with your doctor before starting if you have heart disease, a recent heart attack, unstable angina, severe aortic stenosis, low or uncontrolled high blood pressure, or are pregnant. Harvard Health also urges caution for people who take medications that affect sweating or blood pressure. Skip the sauna when you are sick with a fever, after heavy drinking, or if you feel unwell that day. Children should use lower temperatures, short sessions, and adult supervision. This guide is educational and is not medical advice.

What to expect in your first week

The first two sessions often feel harder than you expect. You may sweat late, feel your heart pound, and want out after 6 or 7 minutes. That is normal. By session three or four, most people start sweating within a few minutes, sit longer on the upper bench, and enjoy the first ladle of löyly. Sleep often feels deeper on sauna nights. By the end of the week, you will know your sweet spot: the temperature, bench height, and round length that leave you relaxed rather than drained.

Frequently asked questions

How long should you stay in a traditional sauna?

Most people stay 8 to 15 minutes per round, with two to four rounds per session. Beginners should start with 6 to 10 minutes. Leave sooner if you feel dizzy or unwell.

Should you shower before and after a sauna?

Yes. A warm shower before keeps the benches clean and helps you sweat sooner. A cool shower after each round and at the end helps bring your body temperature down and rinses off sweat.

How much water do you put on sauna rocks?

Start with one small ladle, about 2 to 4 ounces, poured on the center of the stones. Wait about 30 seconds before adding more. Only pour on the stones, never on the heating elements or controls.
