Sauna vs Steam Room: Differences, Benefits and Which Is Better
Sauna vs steam room: how they differ in heat, humidity and feel, what the research says about each, and which one suits you.
A sauna uses dry heat at about 160–195°F with 10–20% humidity, while a steam room uses moist heat at about 110–120°F with close to 100% humidity. As of October 2026, “sauna vs steam room” gets about 5,000 searches a month in the US, and the answer comes down to how you like your heat. Saunas feel hot and dry. Steam rooms feel humid, heavy and often hotter than the thermometer suggests.

How a sauna works
A traditional sauna heats the air with an electric or wood-burning stove topped with rocks. Humidity stays low until you ladle water onto the rocks, which Finns call löyly, releasing a burst of steam. Infrared saunas skip the hot air and warm your body directly with infrared panels at 120–165°F. Read infrared vs traditional for that comparison.
How a steam room works
A steam room pumps steam from a generator into a sealed, tiled or acrylic room until the air is saturated. At around 100% humidity, sweat can’t evaporate to cool you, so 115°F feels intense. Condensation on your skin is mostly steam, not just sweat.
Sauna benefits
- Heart health: a 2015 JAMA Internal Medicine study of 2,315 Finnish men found those who used saunas four to seven times a week had lower rates of fatal cardiovascular disease and death from all causes than once-a-week users. This is an association, not proof.
- Brain health: a 2017 Age and Ageing study from the same Finnish group linked frequent sauna use to lower dementia and Alzheimer’s risk.
- Recovery and relaxation: heat increases circulation and many users report reduced muscle soreness.
Steam room benefits
- Breathing: many people find moist heat soothing for congestion, though evidence is mostly anecdotal.
- Skin: humidity can feel better on dry skin than dry heat.
- Lower temperature: the lower air temperature suits people who find 180°F saunas uncomfortable.
Dry sauna vs wet sauna
“Wet sauna” usually means a traditional sauna where water is thrown on the rocks. It’s not a different room. Many sauna-goers start dry, then add löyly as the session builds. A true steam room is a different environment entirely, at lower temperature and full saturation.
Which is better for you?
Choose a sauna if:
- You like intense, dry heat and the ritual of löyly
- You want the option of a home unit (far easier to install than a steam room)
- You’re motivated by the cardiovascular research
Choose a steam room if:
- Dry heat irritates your airways or skin
- You prefer lower temperatures
- You mainly want relaxation and congestion relief
Can you have a steam room at home?
A full home steam room needs vapour-sealed walls and ceiling, waterproof surfaces, a sloped ceiling to stop drips, a floor drain and a steam generator. It’s essentially a shower renovation. Portable steam tents are a cheap alternative: owners of the SereneLife steam sauna measure 110–120°F and warn that steam dampens the room, so run a dehumidifier.
A home sauna is far simpler. Plug-in infrared cabins start around $2,000, and outdoor traditional kits run $4,000–$8,500 plus extras. See our best home saunas for picks.
Safety for both
- Limit sessions to 10–20 minutes and leave if you feel dizzy.
- Hydrate before and after, and skip alcohol.
- Check with your doctor first if you’re pregnant or have heart or blood pressure conditions.
- Shower afterwards. Steam rooms in particular are warm, damp environments.
Frequently asked questions
What is the difference between a sauna and a steam room?
A sauna uses dry heat at about 160–195°F with low humidity, while a steam room uses moist heat at about 110–120°F with close to 100% humidity. Saunas feel hot and dry; steam rooms feel humid and often hotter than their temperature suggests.
Is a sauna or steam room better for you?
Neither is clearly better overall. Most long-term research on cardiovascular health and longevity studied traditional Finnish saunas. Steam rooms are often preferred for congestion and dry skin. Choose the one you'll use consistently.
Which is better after a workout, sauna or steam room?
Both relax muscles after exercise. Saunas have more research on endurance and recovery, while steam rooms may feel better for breathing and skin. Hydrate well either way, since both cause heavy sweating.
Is a dry sauna or wet sauna better?
A "wet sauna" usually means a traditional sauna where you throw water on hot rocks to create steam (löyly). It's the same sauna, run more humid. Many people like starting dry and adding steam as the session goes on.
Can you have a steam room at home?
Yes, but it's more involved than a sauna. Steam rooms need fully sealed, waterproof walls, a drain and a steam generator. Portable steam tents cost about $150–$400 but reach only about 110–120°F, by owners' measurements.
