Infrared sauna vs traditional sauna – what is the difference and which suits you?

Traditional sauna or infrared sauna? It is one of the most common questions we get. The answer depends entirely on what you want out of your sauna sessions – and at the end of this article there is a third option that makes the question redundant.

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

The answer is not that one option is better than the other. It is about what you are looking for – and how you will actually use your sauna. This article sets out the differences simply, without unnecessary complication.

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

The fundamental dividing line is how the heat reaches the body.

A traditional sauna heats the air in the room to high temperatures – usually between 70 and 100 °C. The air warms the skin, you begin to sweat heavily, and when you pour water on the hot sauna stones steam forms – what we call löyly. That is the core of Nordic sauna culture and the feeling generations of Scandinavians grew up with.

An infrared sauna works in a completely different way. Infrared panels emit radiation that heats the body directly – from within – without having to heat the air in the room nearly as much. The temperature in the cabin is lower, usually 40–60 °C, yet the 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 sunshine – the heat is felt from within rather than from without.

The traditional sauna – the heat, the löyly and the Nordic experience

There is a reason the traditional sauna has 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 on the hot sauna stones, löyly is created – the humid, intense steam that is the heart of Nordic sauna culture. Humid air conducts heat to the body far more effectively than dry air, which means a sauna with löyly produces a deeper, more powerful physiological response. The pulse rises, sweating increases and the body mobilises its heat reserves.

It is that feeling – the heat, the steam, the almost meditative focus on breathing – that many describe as irreplaceable. And it is that feeling an infrared sauna, however effective it is for recovery, cannot quite replicate.

A traditional sauna suits you if you:

• Want classic Nordic sauna culture with löyly and steam

• Like high temperatures – 80 to 100 °C – and the intense heat they give

• Want to site the sauna outdoors in the garden and combine it with stepping out into the cold

• Value sauna bathing as a social ritual with family or friends

• Want to combine the sauna with an ice bath for contrast therapy

The infrared sauna – deeper recovery at a lower temperature

An infrared sauna has a different strength. It suits you if you want deep muscle relaxation and recovery – without having to sit in 90-degree air to get it.

At 40–60 °C the cabin is far more accessible. You can sit longer, breathe more easily and still sweat effectively – in some respects more deeply, because the IR radiation penetrates the muscles directly rather than simply warming the skin from outside. It is that property that makes infrared saunas particularly popular for pain relief, stiff joints and post-training recovery.

An infrared sauna also warms up considerably faster. Where a traditional sauna can take 30 to 60 minutes to reach temperature, an infrared sauna is ready in 10 to 20 minutes. That makes it easier to fit into a daily routine – you start it from the app as you finish training and step in when you get home.

An infrared sauna suits you if you:

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

• Prefer a milder temperature – 40 to 60 °C – that is easier to sit in for longer

• Are looking for deep muscle relaxation, pain relief or recovery after training

• Want fast warm-up and easy everyday use via a WiFi app

• Value lower energy consumption and more efficient operation

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

The Swedish Cold Hybrid Sauna is the answer to a question you should not have to ask. It is a free-standing indoor sauna for 4–6 people that combines a 6 kW Harvia heater with full spectrum infrared heat in the same cabin – and it can run traditional heat, infrared heat or both at once, all from a touch panel or a WiFi app.

But it is not only the technology that makes it distinctive. Swedish Cold has built the Hybrid Sauna as a premium product in every detail – with features normally found only in professional spa facilities.

The advantages of a combination sauna:

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

• No compromises. You do not have to give up the löyly experience to get the IR benefits – or the other way round.

• 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. Ideal 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 gives the strongest health effects – 50 % lower cardiovascular mortality and 66 % lower dementia risk according to the KUOPIO study. Two to three times a week gives noticeable benefit. Sessions of 15–20 minutes are optimal. Read more in our article on how often you should use a sauna according to research.

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

3. Do infrared and traditional saunas solve different problems?
Yes – and that is the heart of the whole comparison:

4. Can you use an infrared sauna every day?
Yes. Because the temperature is lower – 40–60 °C compared with 80–100 °C in a traditional sauna – daily infrared sauna use is safe and practical for most people. It is one of the big practical advantages.

5. Should you have both types of sauna?
Ideally, yes. Traditional and infrared saunas complement each other rather than compete. They activate partly different physiological mechanisms and suit different occasions. On a Saturday evening you may want löyly and Nordic heat. On a weekday after work, a quick 20-minute session of infrared heat fits better. With the Swedish Cold Hybrid Sauna you do not have to choose – you get both in one system.
