How to Use a Sauna for Beginners: Your First-Session Guide
Learning how to use a sauna for beginners comes down to one idea: start low and go short. For your first session, set a traditional sauna to 65–70°C (150–160°F) — or use an infrared cabin at 50–65°C (120–150°F) — sit on the cooler lower bench, and stay just 5–10 minutes. Drink about 500 mL of water beforehand, breathe normally, and step out the moment you feel lightheaded. Then cool down for 5–10 minutes and rehydrate. That gentle first round is all it takes to start the ritual safely.
Key Takeaways
- Temperature: Beginners start at 65–70°C in a traditional sauna, or 50–65°C in an infrared cabin.
- Time: Keep your first session to 5–10 minutes; build toward 15–20 minutes only as you adapt.
- Hydration: Drink roughly 500 mL before and rehydrate after — you can lose significant fluid through sweat.
- Position: Sit on the lower bench first; heat rises, so the top bench can be 15–20°C hotter.
- Cool down: Spend 5–10 minutes cooling in fresh air, a cool shower, or a cold plunge before a second round.
- Safety: Skip the sauna if you are unwell, have had alcohol, or are pregnant without a doctor's sign-off.
Before Your First Session
Good sauna use starts before you step inside: shower, dry off, and bring a towel to sit on. A quick rinse keeps the bench clean, and dry skin actually begins to sweat sooner than damp skin. Set aside 30–40 minutes so you never feel rushed to hit a number on the timer.
Know what to expect from the heat. A traditional Finnish-style room feels dry with a sharp warmth you can deepen by ladling water on the rocks; an infrared cabin feels gentler because it warms your body directly rather than the air. If you own a Grade-A Canadian cedar cabin like Calore's, let it pre-heat fully so the temperature is steady when you enter. New to choosing between styles?

What to Wear in a Sauna
Wear whatever is comfortable and breathable — there is no dress code for a home sauna. A swimsuit works well because you can shower or plunge in it afterward; loose cotton shorts and a t-shirt are just as good. In a private cabin, many people simply wrap in a towel or go without.
Two rules matter more than the outfit: always sit on a towel, and leave metal behind. Jewellery, watches, and phone cases heat up fast and can burn the skin, so leave them outside. Skip shoes on the cedar; if you want your feet covered, sandals are fine. A wool sauna hat and a bench towel from our sauna accessories make longer sessions more comfortable.
First-Session Temperature: Start Cooler Than You Think
For your first visit, aim low. A traditional sauna is comfortable across roughly 65–80°C (150–175°F), but beginners should start near 65–70°C (150–160°F) and raise it only once they feel settled. An indoor infrared sauna runs cooler — about 50–65°C (120–150°F) — because it heats your body directly, which is why many first-timers find infrared easier to tolerate.
| Sauna type | Beginner start | Typical comfort range |
|---|---|---|
| Traditional / cedar | 65–70°C (150–160°F) | 65–80°C (150–175°F) |
| Infrared cabin | 50–55°C (120–130°F) | 50–65°C (120–150°F) |
| Bench choice | Lower bench | Upper bench once adapted |
Stat: Because heat rises, the top bench of a traditional sauna can sit 15–20°C hotter than the bottom. Starting low, on the lower bench, is the single easiest way to make a first session comfortable.
How Long Should a Beginner Stay In?
Keep your first round to 5–10 minutes. That is long enough to warm through and start sweating without overtaxing your system. As your body adapts across several sessions, you can extend to 15–20 minutes, but longer is not better — the benefits come from consistency, not endurance.
Think in rounds rather than one long stint: 5–10 minutes in, a full cool-down, then an optional second round. Set a timer so you are not guessing, and treat any dizziness or strong discomfort as your real signal to leave, whatever the clock says.
How to Stay Hydrated
Hydration is the safety habit that matters most, because you sweat steadily the whole time. Drink about 500–600 mL (16–20 oz) of water in the hour or two before your session, and rehydrate again afterward to replace what you lost.
Room-temperature water is easiest on the system. If you do multiple rounds or sweat heavily, add a pinch of electrolytes to replace lost sodium and potassium. Avoid alcohol entirely — it deepens dehydration and blunts the warning signs your body would otherwise send.
Cooling Off and the Hot–Cold Contrast
Never skip the cool-down. After a round, spend 5–10 minutes cooling in fresh air, under a cool shower, or in a cold plunge. This lets your heart rate and blood pressure settle before you decide whether to go back in.
The heat-then-cold pattern is the heart of the ritual — breathe deep, heat up, cool down, relax, repeat. Warmth widens your blood vessels; cooling narrows them again, and that push-pull is what leaves you feeling clear and loose. If you finish hot and flushed with no cool-down, you are more likely to end up with a mild headache because your blood pressure stays elevated.
Sauna Etiquette
Etiquette keeps a shared sauna pleasant and a home sauna clean. The basics: shower before you enter, always sit on a towel, and keep conversation low and calm — the room is meant for quiet.
Leave phones and cameras outside; the heat can damage them and other bathers value the privacy. In a traditional sauna, ask before adding water to the rocks, since the resulting steam raises the heat for everyone. Wipe down your bench when you leave.
Common Beginner Mistakes
Most rough first sessions trace back to a handful of avoidable errors. Sidestep these and your first sauna will feel restorative rather than draining.
- Starting too hot. Cranking straight to 90°C on day one is the fastest route to feeling faint. Start at 65–70°C.
- Staying too long. Pushing past comfort for a "better" result backfires; 5–10 minutes is plenty at first.
- Under-drinking. Entering already thirsty, or skipping water afterward, is the top cause of post-sauna headaches.
- Skipping the cool-down. Going straight from heat to your day leaves you flushed and light-headed.
- Sitting up top first. The upper bench is much hotter — earn it over a few sessions.
Safety First: When to Skip the Sauna
Saunas are safe for most healthy adults, but heat is a real physiological load. Do not use a sauna if you are unwell with a fever, have had alcohol or recreational drugs, or have just eaten a large meal (wait about two hours). If you have heart disease, high or unstable blood pressure, kidney disease, or you are pregnant or breastfeeding, talk to your doctor first — this is a medical decision.
Leave immediately if you feel dizzy, nauseous, faint, confused, short of breath, or notice chest pain. These are your body's signals to cool down and rest, not to push through.
Who Should Wait — and the "200 Rule"
Beyond the cautions above, listen to your own tolerance. The old Finnish "200 rule" — keeping the sum of temperature in Fahrenheit and humidity percentage under about 200 — is a rough traditional guide to a comfortable, safe löyly (steam) balance; in practice, starting cool and low-humidity does the same job for a beginner.
Research on regular sauna bathing, including long-running Finnish cohort studies published in JAMA Internal Medicine, links frequent use to cardiovascular benefits in healthy adults — but that evidence is about consistent, sensible sessions, not extreme heat or long stints. Build the habit gently.
Your First Session, Step by Step
- Hydrate and shower. Drink ~500 mL of water and rinse off so you enter clean and dry.
- Set a low temperature. 65–70°C for a traditional cabin, 50–55°C for infrared.
- Sit low, on a towel. Take the lower bench, breathe normally, and relax.
- Stay 5–10 minutes. Set a timer; leave earlier if you feel unwell.
- Cool down for 5–10 minutes. Fresh air, a cool shower, or a cold plunge.
- Rehydrate and rest. Drink more water, then decide if you want one more short round.
The Calore Verdict
Your first sauna should feel easy, not heroic. Start cool, sit low, stay short, drink water, and cool down — then repeat the ritual as your body adapts. Key finding: a 5–10 minute first round at 65–70°C (or 50–65°C infrared), followed by a proper cool-down and rehydration, is the safe, effective way for beginners to build a lasting sauna habit.

Frequently Asked Questions
How do you use a sauna properly for the first time?
Shower first, sit on a towel on the lower bench, and set the sauna to about 65–70°C (150–160°F). Stay 5–10 minutes for your first session, breathe normally, and step out the moment you feel dizzy or lightheaded. Cool down in fresh air or a cool shower for 5–10 minutes, then rehydrate. Build up temperature or time gradually over later visits.
How long should a beginner stay in a sauna?
Start with 5–10 minutes per round. As you adapt over several sessions you can work up to 15–20 minutes, but there is no benefit to pushing past comfort. Leave earlier if you feel unwell — time is a guideline, not a target.
What temperature should a beginner set a sauna to?
For a traditional sauna, start around 65–70°C (150–160°F); the wider comfort range is roughly 65–80°C. An infrared sauna runs cooler, usually 50–65°C (120–150°F), which many beginners find easier to tolerate. Begin at the low end and raise the temperature only once you are comfortable.
What should I wear in a sauna?
Wear whatever is comfortable and breathable: a swimsuit, loose cotton shorts and a t-shirt, or simply a towel in a private home sauna. Always sit on a towel, skip shoes inside, and leave metal jewellery and phones outside, as they heat up quickly.
Can I use a sauna with high blood pressure or during pregnancy?
If you have high or unstable blood pressure, heart disease, kidney disease, or are pregnant, talk to your doctor before using a sauna. Many people with well-controlled conditions can use one safely at lower temperatures and shorter times, but this is a medical decision — get personalised advice first.
Should you cool down after a sauna?
Yes. Spend 5–10 minutes cooling in fresh air, a cool shower, or a cold plunge before deciding whether to do another round. The hot-to-cold contrast helps your circulation return to normal and skipping it can leave you feeling flushed or headachy because your blood pressure stays elevated.
