Infrared vs Traditional Sauna: A Round-by-Round Comparison for Men

Open the door of a traditional sauna and the heat meets you at the threshold: thick, dry air, a smell of hot wood, and a hiss when someone ladles water onto the stones. Open the door of an infrared sauna and it is almost polite. The air is merely warm, the room is quiet, and the heat creeps up on your skin over several minutes.

Both have loyal fans, and both get you hot. So rather than declare a single winner, we put infrared vs traditional sauna head to head across seven rounds that matter to men who use one every week.

Round 1: the heat itself

A traditional sauna heats the air and a pile of stones, typically to around 66–91°C (150–195°F). You sit in that hot air, and the heat reaches you from every direction at once.

An infrared sauna works differently. Panels on the walls give off infrared heat that warms your body more directly than the air, which stays at roughly 43–57°C (110–135°F). You heat up from the outside in, more slowly.

Humidity differs too. An infrared sauna stays dry. A traditional sauna is dry until someone throws water on the stones, and then the humidity, and how hot it feels, jumps for a minute or two.

Verdict: traditional, if you want intensity. Infrared, if you want heat without the hit.

Round 2: how it feels

In a traditional sauna, a 15-minute round can feel like plenty. The steam is part of the ritual: in Finland the burst of steam from water on the stones even has its own name, löyly, and for many regulars it is the best moment of the session. It is a social room, too, where conversation comes naturally.

In an infrared sauna you can breathe easily, sit for longer and read or listen to something. Some people find it far more relaxing. Others miss the drama of a proper hot room.

Verdict: a split decision. It depends entirely on what you are after.

Round 3: fertility

Here the honest answer is a draw. Both types raise your body temperature, and the testes work best a few degrees below your core. The strongest human evidence comes from a traditional sauna: the 2013 Padova study on sauna heat and sperm found that two 15-minute sessions a week for three months lowered sperm count and motility, which recovered only months after the men stopped.

Infrared has very little fertility research behind it, so nobody can say it is safe or unsafe for sperm. Its lower air temperature may mean less heat, but people tend to stay in longer, which can even it out.

The practical answer is the same for both: keep sessions sensible, and cool during them rather than after. A cooling insert held in place by your underwear lasts longer in an infrared sauna, because the air is cooler. If you are shopping around, here is how different cooling briefs compare.

Verdict: a draw. Manage the heat in either one.

Round 4: after training

Both make a good wind-down after the gym. A traditional sauna gives you a short, intense session, so keep it brief when you are already tired. An infrared cabin lets you sit longer at a gentler temperature, which some people prefer after a hard day. Research on saunas and muscle recovery is limited, so choose the one you enjoy. Our post-workout sauna routine covers timing and water.

Verdict: infrared by a nose for tired legs, traditional for a quick, sharp finish.

Round 5: pairing with cold water

The classic contrast is a traditional sauna followed by a cold plunge: the bigger the swing, the more striking the effect. Infrared followed by a cold shower works too, just more gently. If you want to try it, start with our guide to a contrast routine with a cold plunge, which covers the mistakes most people make.

Verdict: traditional, clearly.

Round 6: living with one at home

• Space: infrared cabins are often compact. Traditional saunas usually need room for a heater and proper benches.
• Power: a traditional heater may need dedicated electrical work, so speak to an electrician first.
• Warm-up time: traditional saunas usually take longer to reach temperature.
• Upkeep: both need cleaning and airing, and the stones in a traditional sauna need checking over time.
• Household: a partner who hates intense heat may use an infrared cabin far more often.

Verdict: infrared for small spaces and easy use, traditional for purists who want the real thing.

Think honestly about how you will use it on a normal, busy Tuesday, not on a perfect Sunday. The sauna you can switch on and use within minutes tends to get used far more often than the one that needs planning.

Round 7: where you can actually use one

Availability decides more than people admit. Most gyms, spas and public saunas are traditional, so if you travel or train in different places, you will meet a stove and stones far more often. Infrared is more common in dedicated studios and in homes.

Verdict: traditional, simply because it is everywhere.

Infrared vs traditional sauna: the scorecard

Which one for a beginner?

Infrared is often the easier start. The lower air temperature lets you get used to the feeling of sustained heat without the shock of a hot room, and many beginners move on to a traditional sauna later once they know their limits. If your only option is traditional, start on the lowest bench with short rounds and you will be fine.

Can you use both?

Plenty of people do. A traditional sauna for a short, intense session after training, and an infrared cabin for a longer, quiet session on a rest day, is a sensible split. Just remember that the heat adds up across both, so count them together if fertility is on your mind, and keep at least a couple of heat-free days each week.

What people get wrong about infrared

The most common mistake is assuming that cooler air means no real heat. Infrared still raises your body temperature, and because it feels gentle, people often stay much longer than they would in a traditional sauna. The second is expecting dramatic results from sweat alone. Most of what you lose in any sauna is water, and it comes straight back when you drink.

How to try both before you choose

If you are deciding which to buy or which gym to join, test both properly. A single session tells you very little.

1. Get a day pass or a short membership somewhere that has both.
2. Use each one for two weeks, at your normal times.
3. Notice how you feel afterward, how you sleep and whether you look forward to going.
4. Pick the one you kept wanting to go back to.

Safety is the same in both

Drink water before and after, leave the moment you feel dizzy or unwell, skip alcohol, and check with your doctor first if you have a heart or blood pressure condition. Do not assume an infrared sauna is automatically safer because the air is cooler, or that a traditional one is only for hardened regulars. A long session still raises your body temperature.

The kit works in either

You need the same few things whichever door you choose: a towel, a wool seat mat for a cleaner bench, and water for afterward. A felt sauna hat earns its place in a traditional sauna, where the hottest air sits right at head height. For the rest, here is what to wear in either kind of sauna, and how long to stay in once you are there.

So which one is for you?

• You love intense heat, steam and a social room: traditional.
• You want long, quiet sessions or you are new to sauna: infrared.
• You train hard and want a quick finish: traditional, kept short.
• You are building one at home with limited space: infrared is the easier start.

Whichever you pick, the one you use every week beats the one you think you should like.

And if you are still torn, start with whatever is closest to where you already train. Convenience is the strongest predictor of whether a sauna habit lasts, far more than the type of heat on the other side of the door.
