Infrared Sauna vs. Regular Sauna – What's the Difference, and Which One Is Right for You?

Traditional sauna or infrared sauna? That’s one of the most common questions we get. The answer depends entirely on what you want to get out of your sauna experience—and at the end of this article, there’s a third option that makes the question moot.

Saunas are more popular than ever. Research supports their health benefits, more and more people are installing saunas at home, and interest in both traditional saunas and infrared saunas is growing significantly. But once you decide to buy a sauna, the same question almost always comes up: which option should I choose?

The answer isn't that one option is better than the other. It comes down to what you're looking for—and how you'll actually use your sauna. This article explains the differences in a simple way, without any unnecessary complications.

What is the difference between an IR sauna and a regular sauna?

The fundamental distinction lies in how heat reaches the body.

Traditional sauna heats the air in the room to high temperatures—usually between 70 and 100 °C. The air warms your skin, you start to sweat profusely, and when you pour water onto the hot sauna stones, steam forms—what we call löyly. This is the essence of Nordic sauna culture and the experience that generations of Scandinavians have grown up with.

Infrared sauna works in a completely different way. Infrared panels emit radiation that heats the body directly—from the inside—without having to heat the air in the room as intensely. The temperature in the cabin is lower, usually 40–60 °C, but sweating can still be deep and effective because the heat penetrates the skin and muscles directly.

A simple analogy: a traditional sauna is like sitting in a hot oven. An infrared sauna is more like sitting in the sunshine—the heat feels like it’s coming from the inside rather than the outside.

Traditional sauna – the heat, the steam, and the Nordic experience

There’s a reason why the traditional sauna have survived for thousands of years. The experience is hard to replace.

When the air in the cabin reaches 80–100 °C and you pour water onto the hot sauna stones, löyly is created—the moist, intense steam that is at the heart of Nordic sauna culture. Moist air transfers heat to the body much more effectively than dry air, which means that a sauna with löyly produces a deeper, more powerful physiological response. Your heart rate rises, sweating increases, and your body mobilizes its heat reserves.

It’s that feeling—the heat, the steam, the almost meditative focus on breathing—that many describe as irreplaceable. And it’s that feeling that an infrared sauna, no matter how effective it is for recovery, can’t quite replicate.

A traditional sauna is perfect for you if:

• Want to experience the classic Nordic sauna culture with löyly and steam

• Prefers high temperatures—80 to 100 °C—and the intense heat they generate

• I want to set up the sauna outdoors in the garden and combine it with stepping out into the cold

• Values taking a sauna as a social ritual with family or friends

• I want to combine a sauna with an ice bath for contrast therapy

Infrared Sauna – Deeper Recovery at Lower Temperatures

Infrared sauna offers a different kind of experience. It’s perfect for those who want deep muscle relaxation and recovery—without having to sit in 90-degree air to achieve it.

At 40–60 °C, the cabin atmosphere is much more comfortable. You can stay in longer, breathe more easily, and still sweat effectively—in fact, more deeply in some respects, since the infrared radiation penetrates the muscles directly rather than just warming the skin from the outside. It is this characteristic that makes the infrared sauna particularly popular for pain relief, stiff joints, and post-workout recovery.

Infrared saunas also heat up much faster. While a traditional sauna can take 30 to 60 minutes to reach the right temperature, an infrared sauna is ready in 10 to 20 minutes. This makes it easier to incorporate into your daily routine—you can start it via the app when you finish your workout and step inside when you get home.

An infrared sauna is right for you if:

• Want a simple indoor installation without complicated electrical or ventilation requirements

• Prefers milder temperatures—40 to 60 °C—which are easier to stay in for a long time

• Looking for deep muscle relaxation, pain relief, or post-workout recovery

• Wants fast heating and easy everyday use via a Wi-Fi app

• Values lower energy consumption and more efficient operation

Why choose when you can have both? Swedish Cold Hybrid Sauna

Swedish Cold Hybrid Sauna is the answer to the question you shouldn’t have to ask. It’s a freestanding indoor sauna for 4–6 people that combines a 6 kW Harvia heater with full-spectrum infrared heating in the same cabin—and can operate using traditional heat, infrared heat, or both simultaneously, all via a touch panel or a Wi-Fi app.

But it’s not just the technology that makes it unique. Swedish Cold has designed the Hybrid Sauna to be a premium product in every detail—with features normally found only in professional spa facilities.

The benefits of a combination sauna:

• Full flexibility. Three modes in one: traditional, infrared, or combined. You can tailor the experience to your mood, energy level, and goals.

• No compromises. You don’t have to give up the sauna experience to enjoy the benefits of infrared—or vice versa.

• Cost-effective. A high-quality hybrid sauna costs less than buying a traditional sauna and an infrared sauna separately.

• Space-efficient. One cabin instead of two. Perfect for home use where space is a factor.

FAQ – Infrared Sauna vs. Traditional Sauna

1. How often should you use a traditional sauna?
Research shows that 4–7 times a week provides the greatest health benefits—a 50% lower risk of cardiovascular mortality and a 66% lower risk of dementia, according to the KUOPIO study. 2–3 times a week provides noticeable benefits. Sessions lasting 15–20 minutes are optimal. Read more in our article about how often you should use the sauna, based on research.

2. How often should you use an infrared sauna?
3–5 times a week is optimal. The lower temperature of the infrared sauna—40–60 °C—means the body can handle more frequent use, and sessions can be longer, lasting 20–30 minutes. Daily use is safe for most healthy adults.

3. Do infrared saunas and traditional saunas address different issues?
Yes—and that is the crux of the entire comparison:

4. Can you use an infrared sauna every day?
Yes. Since the temperature is lower—40–60 °C compared to 80–100 °C in a traditional sauna—daily use of an infrared sauna is safe and feasible for most people. That’s one of its major practical advantages.

5. Should you have both types of saunas?
Ideally, yes. Traditional saunas and infrared saunas complement each other rather than compete. They activate somewhat different physiological mechanisms and are suited to different occasions. On a Saturday night, you might want the löyly and Nordic heat. On a weekday after work, a quick 20-minute session in infrared heat is a better fit. With the Swedish Cold Hybrid Sauna, you don’t have to choose—you get both in one system.
