How Long Should You Sit in a Sauna? A Practical Guide to Session Length
Updated October 2026
How long should you stay in a sauna? Most beginners should stay in a traditional sauna for 5 to 10 minutes per round. Once you're used to the heat, 15 to 20 minutes per round is typical. Rather than one long session, do 2 to 3 rounds with a 10 to 20 minute cool-down and water between each. Leave right away if you feel dizzy, nauseous or lightheaded, however long you've been in.
Sauna Session Length by Experience Level

Time per round |
Rounds |
Sessions per week |
|---|---|---|---|

First 1–5 sessions |
5–10 minutes |
1–2 |
2–3 |

Intermediate (after 5–10 sessions) |
10–15 minutes |
2–3 |
2–4 |

Regular sauna-goer |
15–20 minutes |
2–3 |
3 or more |
These are starting points, not targets. Heat tolerance varies with hydration, sleep, what you ate and how hot the sauna is that day.
How Long to Stay by Sauna Type
|
Sauna type |
Typical temperature |
Typical round |
|---|---|---|
|
Traditional or wood-fired (including sauna tents) |
180–200°F (82–93°C) |
5–20 minutes |
|
Steam room |
100–120°F (38–49°C), near 100% humidity |
10–15 minutes |
|
Infrared sauna |
120–150°F (49–65°C) |
20–30 minutes |
Humidity changes everything. Pouring water on the stones (löyly) makes the same temperature feel much hotter, so shorten your round after a big pour.
Your First Sauna Session: A Simple Plan
- Drink water 30 minutes before. Skip alcohol and heavy meals.
- Round 1: 5 minutes. Sit on the lower bench, where it's cooler.
- Cool down for 10–15 minutes. Step outside, take a lukewarm shower, and sip water.
- Round 2: 5–10 minutes if you feel good. Stop at one round if you don't.
- Finish with water and a light snack. Add a few minutes per round over the next few weeks.
Why Multiple Rounds Beat One Long Session
The traditional Finnish rhythm is heat, cool, rest, repeat. Short rounds with real cool-downs let your body recover between bouts, so you can enjoy more total heat with less strain than a single long sit. Many people add a cold plunge, a snow roll or a cold shower between rounds once they're comfortable with the heat.
How Often Should You Use a Sauna?
Two to three sessions a week is a good start. Many regular users go 4 or more times a week. A long-running Finnish study of middle-aged men (Laukkanen et al., JAMA Internal Medicine, 2015) found that men who used a sauna 4–7 times a week had lower rates of fatal cardiovascular events than men who went once a week. That is an association, not proof that sauna caused it, but it's one reason consistent use is the norm in Finland.
Signs It's Time to Get Out
- Dizziness or lightheadedness
- A racing or pounding heartbeat
- Nausea or stomach discomfort
- Skin that feels like it's burning
- Sudden weakness or fatigue
Get out, sit or lie down somewhere cool, and drink water. Don't push through these to hit a time goal.
Who Should Check With a Doctor First
Talk to your doctor before using a sauna if you are pregnant, have heart disease, high or low blood pressure, diabetes, or take medication that affects heart rate or sweating. Don't use a sauna after drinking alcohol.
Getting the Most From Your Time in a Sauna Tent
A wood-fired sauna tent reaches the same 180–200°F as a traditional sauna, so the same timing applies. Because it sits outside, cool-downs are easy: step out into the fresh air or snow between rounds. A wool sauna hat keeps your head comfortable, and a sauna thermometer shows you how hot it really is.

FAQ
How long should you stay in a sauna the first time?
5 to 10 minutes, then cool down. If you feel good, do a second short round.
Is 20 minutes in a sauna too long?
For an experienced user in a traditional sauna, 15–20 minutes per round is common. For beginners it's too long. Build up over several weeks.
How long should you sit in a sauna after a workout?
Rehydrate first, then use the same times above. Many people keep post-workout rounds a little shorter because they're already warm and have lost fluid.
Can you stay in a sauna for an hour?
Not in one sitting. An hour of total sauna time is normally split into 2–3 rounds with cool-downs between them.
How long should you stay in an infrared sauna?
Infrared saunas run cooler, so 20–30 minutes is typical.
