Infrared Saunas: A Complete Guide
An infrared sauna warms your body with radiant panels at a low air temperature. Here is how infrared saunas work, their pros and cons, and who they suit.
The short answer
An infrared sauna uses radiant panels to warm your body directly at a low air temperature (around 45–60°C), rather than heating the air and stones. It offers gentle, quick, low-energy warmth — but no steam and no löyly.
Infrared saunas have surged in popularity, and they are a genuinely different product from a traditional sauna. Understanding how they work makes it easy to decide whether one is right for you.
How infrared works
Instead of a stove heating the air, infrared panels emit radiation that your body absorbs directly — much like the warmth of the sun on a cool day. The air itself stays relatively cool (around 45–60°C), but you still warm up and sweat because the energy lands on your skin.
The trade-offs
Pros
- Gentle, low-temperature radiant warmth
- Fast warm-up (10–15 minutes)
- Lower energy use per session
- Easier for people who dislike intense heat
- Often compact, plug-in units
Cons
- No löyly — you cannot throw water
- Not the traditional high-heat experience
- Milder hot–cold contrast with a plunge
- Panels, not a stove and stones
Who it suits
Infrared appeals to people who want gentle, quick warmth without the intensity of a 90°C room — and who do not mind losing the steam and ritual. If, on the other hand, the hiss of water on stone is the whole point for you, you want a traditional sauna.
Making the call
We lay the two side by side in infrared vs. traditional sauna. Neither is “the real sauna” in a way that makes the other fake — they are different tools that happen to share a name. Match the machine to the experience you actually want.
Because infrared warms you rather than the air, sessions feel different from a traditional sauna: gentler, at a lower temperature, and often longer, since the milder heat is easy to tolerate. Some people who find 90°C uncomfortable enjoy infrared for exactly this reason. Just remember there is no löyly — if the ritual of water on stones matters to you, infrared is the wrong tool.
Placement, power and practicalities
One of the appeals of infrared saunas is how simple they are to set up. Many are self-contained, plug-in cabins that need only a suitable electrical outlet — no dedicated heater circuit, no chimney, and often no separate ventilation build. That makes them easy to place in a spare room, a corner, or even a large closet, and to move if you rearrange the space later.
Before buying, confirm the power requirement and that you have an appropriate outlet nearby, and check the cabin materials — because you sit in an enclosed warm space, low-emission, non-toxic construction is worth looking for. Panel coverage matters more than headline wattage: well-distributed panels give even warmth around the body. Because the air stays relatively cool, infrared cabins also warm up quickly, so they suit spontaneous, shorter sessions. If the low-fuss setup and gentle heat appeal to you more than steam and high temperatures, an infrared cabin is an easy, flexible way to bring warmth into a home.
Frequently asked questions
How does an infrared sauna work?
Radiant panels emit infrared energy that your body absorbs directly, warming you at a low air temperature (about 45–60°C) rather than heating the whole room to a high temperature.
Can you throw water in an infrared sauna?
No. Infrared saunas use electric panels, not a stone heater, so there is no löyly and adding water could damage the electronics.
Is an infrared sauna as good as a traditional one?
It depends on what you want. Infrared offers gentle, low-temperature warmth and low running cost; traditional offers high heat, löyly and the classic ritual. They are different experiences.
Are infrared saunas hot?
The air is much cooler than a traditional sauna — around 45–60°C — but you still feel warm and sweat because the panels heat your body directly.
Do infrared saunas use less energy?
Generally yes, because they heat to a lower temperature and warm you directly rather than bringing a whole room and stone mass up to 90°C.
Are infrared sauna sessions longer than traditional ones?
Often, because the lower air temperature is easier to tolerate, some people sit for longer in an infrared cabin. As always, listen to your body, stay hydrated, and stop if you feel unwell rather than aiming for a set time.
Do infrared saunas need special wiring?
Often not — many are plug-in cabins that use a standard suitable outlet, unlike a traditional sauna which needs a dedicated heater circuit. Always confirm the specific model power requirement before buying.
What should I check in an infrared sauna cabin?
Even panel coverage (more important than headline wattage), low-emission non-toxic materials since you sit in an enclosed space, the right size for your users, reliable controls, and a clear warranty from a reputable maker.
