The short answer: A traditional sauna heats the air around you to 150–195°F. An infrared sauna uses radiant panels to warm your body directly, while the air stays much cooler — usually 110–140°F. Same idea, completely different experience. Infrared is generally easier to sit in longer, easier to breathe in, and pairs naturally with red light therapy. Traditional saunas deliver a more intense, humid, communal heat.
Here in Owensboro, we run infrared saunas — so yes, we have a horse in this race. But this guide is the honest comparison we give guests who ask, whether they book with us or not.
How Each Type of Sauna Actually Works
This is the part most comparison articles gloss over, and it's the reason the two experiences feel nothing alike.
Traditional Sauna — It Heats the Air
A traditional sauna (often called a Finnish sauna) uses a heater — electric, wood-burning, or gas — to bring the air temperature up to roughly 150–195°F. You sit inside that hot room and the heat transfers to your body through the air and any steam.
Throw water on the rocks and you get löyly — a burst of steam that spikes the humidity and, for many people, the intensity. Traditional saunas run somewhere between 10–20% humidity when dry, and much higher when someone's ladling water.
What that means for you: the room itself is hot. You feel it immediately, in your lungs as much as your skin. Sessions are typically shorter — 10 to 20 minutes for most people.
Infrared Sauna — It Heats You
An infrared sauna uses carbon or ceramic panels that emit infrared radiant heat. This is the same spectrum of energy your body produces and gives off naturally. Rather than heating the surrounding air, infrared energy is absorbed directly by your skin and the tissue beneath it.
The air in an infrared sauna usually sits between 110°F and 140°F — noticeably cooler than a traditional sauna. But you still feel warm, because the heat is landing on you, not on the room.
What that means for you: the air is easier to breathe, the heat feels gentler and more even, and it's generally comfortable to stay in longer — often 20 to 40 minutes.
Side-by-Side Comparison
| Traditional Sauna | Infrared Sauna | |
|---|---|---|
| How it heats | Air temperature rises; heat transfers to you | Panels emit infrared energy absorbed by your body |
| Air temperature | ~150–195°F | ~110–140°F |
| Humidity | Low when dry; high with steam/löyly | Low, dry heat |
| Warm-up time | 20–45 minutes to heat the room | 5–15 minutes |
| Typical session | 10–20 minutes | 20–40 minutes |
| What it feels like | Intense, enveloping, sometimes humid | Gentle, even, more like deep warmth than hot air |
| Breathing | Hot air in the lungs; some find it difficult | Noticeably easier |
| Room setup | Often communal | Commonly private rooms |
| Red light add-on | Not typical | Frequently paired (e.g., 660nm) |
| Best suited for | Guests who want a short, intense, traditional heat | Guests who want a longer, more comfortable sit |
What Each One Feels Like
Traditional sauna: You open the door and the heat hits you before you step in. Sitting down, the hot air surrounds you — your lungs notice it first. Many people love the ritual: the wood, the steam, the sharp contrast with a cold plunge or a cold shower afterward. It's a bracing experience, and shorter sessions are the norm for a reason.
Infrared sauna: You step in and think, this doesn't feel that hot. Then about five minutes later you realize your shoulders have gone loose and you're genuinely warm — without the hot-air-in-the-lungs feeling. Because the air isn't as hot, you can read, breathe easily, and just sit. Most guests describe it as calmer and less claustrophobic than they expected.
That difference in feel is usually the deciding factor. Almost everyone who has tried both has a strong preference, and it usually isn't about which one is "better" — it's about which one they'll actually use.
Which One Should You Choose?
Go with a traditional sauna if…
- You love the intensity of a short, hot, traditional heat
- You enjoy the ritual of steam and cold plunging afterward
- You like the social, communal sauna culture
- You want the classic Finnish experience
Go with an infrared sauna if…
- You prefer heat you can sit in comfortably for longer
- You want to breathe easily while you warm up
- You want a private room rather than a communal space
- You want red light therapy in the same session
- You're building a routine you'll do multiple times a week, not once in a while
There's no wrong answer. The sauna you'll actually use twice a week beats the one that's technically better but feels like a chore.
A Note on Red Light Therapy (660nm)
Many traditional saunas don't offer it. Many infrared saunas do — and it's worth understanding why people pair them.
Red light therapy uses specific wavelengths of visible red light to support skin and tissue comfort. In our rooms, we use medical-grade 660nm red light alongside full-spectrum infrared heat. The idea is simple: you're already in the room, lying still, warming up — so adding red light costs you nothing in time and makes the session feel more complete.
If you're comparing saunas and one offers red light while the other doesn't, that's a real difference worth weighing.

Is infrared better than a traditional sauna?
Neither is objectively better — they're different experiences. Infrared is gentler and easier to sit in longer, with cooler air and an optional red light pairing. Traditional saunas offer a shorter, more intense, often communal heat. The right choice is the one you'll use consistently.
How often should I use an infrared sauna?
Many regulars use an infrared sauna two to four times a week as part of a general wellness routine. There's no universal schedule — start with once a week, pay attention to how you feel, and adjust. If you have any health condition, check with your doctor first.
How long should an infrared sauna session last?
Many regulars use an infrared sauna two Most people are comfortable in an infrared sauna for roughly 20 minutes, and many stay up to 40. Because the air is cooler than a traditional sauna, it's easier to extend. Start shorter and build up as you learn your comfort level.
What should I wear in an infrared sauna?
Whatever you're comfortable in. Some guests wear a swimsuit, others wear light workout clothing, and some prefer towels. At our facility, every room is private — so it's entirely your call.
Can I use an infrared sauna after a workout?
Yes, and it's a popular time to go. Many guests come in after training or a long day of physical work. We recommend hydrating before, during, and after your session.
Do infrared saunas make you sweat?
Yes. You typically sweat less than in a traditional sauna because the air is cooler, but because the heat penetrates your body more directly, you still sweat — and many people find it more comfortable.
Can I bring a friend?
Yes. We have three private two-person infrared sauna rooms, so you can share the heat. Ask about our Bring a Friend rate.
Is a sauna safe for everyone?
Saunas aren't appropriate for everyone. If you're pregnant, have a heart condition, take medications that affect sweating or blood pressure, or have any other health concern, please talk to your doctor before booking. Our staff is happy to answer questions about the facility, but we don't give medical advice.
