How long you should stay in a sauna depends on the type, the temperature and how used to heat you are, but the honest general answer is shorter than most beginners expect: a first session is a few minutes, a seasoned user in a hot traditional sauna might sit 15 to 20, and the cooler infrared sauna allows a longer session because the heat is gentler. Listening to your body matters more than any single number.
Typical session lengths
In a hot traditional sauna at 175 to 195 Fahrenheit, experienced users commonly sit 15 to 20 minutes, often split into rounds with a cool-down between them, while beginners should start at 5 to 10 and build up over weeks. An infrared sauna runs cooler, so sessions of 20 to 45 minutes are normal because the heat is less intense. A steam room's high humidity makes it feel hotter than its temperature, so sessions there are usually shorter, around 10 to 15 minutes. These are ranges, not prescriptions, and the right length is the one you finish feeling good rather than drained.
How experience changes it
Heat tolerance is trainable: the first few sessions in any sauna should be deliberately short, because the body adapts to heat over weeks and pushing a long session early is how people end up dizzy or put off. Build up gradually, take a cool-down or a cold plunge between rounds if you contrast, and drink water, because a sauna makes you sweat and dehydration is the most common reason a session goes wrong. A beginner who starts at five minutes and adds a little each time reaches a comfortable full session faster than one who tries to tough out twenty on day one.
When to get out
The rule that matters more than any clock is to leave when you feel light-headed, dizzy, nauseous or simply done, rather than waiting for a timer. Heat affects everyone differently and on different days, so the same person's comfortable length varies. If you have a health condition, are pregnant, or take medication that affects blood pressure or heat regulation, the length of a safe session is a question for a clinician rather than a general guide, and this page is not medical advice.
Questions people ask about how long should you stay in a sauna
How long should a beginner stay in a sauna?
Start at 5 to 10 minutes in a traditional sauna and build up over weeks as your heat tolerance improves. In a cooler infrared sauna a first session can be a little longer, but shorter and comfortable beats long and draining.
Is 30 minutes too long in a sauna?
In a hot traditional sauna, usually yes for most people; 15 to 20 is a common experienced session. In a cooler infrared sauna, 30 minutes is within the normal range because the heat is gentler.
How do I know when to get out of a sauna?
Leave when you feel light-headed, dizzy, nauseous or simply finished, rather than waiting for a timer, and drink water. If you have a health condition, the safe length is a question for a clinician.
