Infrared Sauna vs. Traditional Sauna: What’s the Difference?
If you're considering buying a sauna, one of the first questions you'll probably encounter is: What's the difference between an infrared sauna and a traditional sauna?
Although both types of saunas are designed to create a hot, relaxing environment and make you sweat, they produce heat in fundamentally different ways.
A traditional sauna heats the air around you, which then warms your body. An infrared sauna uses infrared light to heat your body more directly, allowing it to operate at a significantly lower air temperature.
So, which is better?
The answer depends on what you're looking for. Traditional saunas provide the intense, high-temperature experience associated with Finnish-style sauna bathing, while infrared saunas offer a gentler heat that many people find easier to tolerate.
Let's take a closer look at how they compare, what the research says, and how to decide which sauna is right for you.
Infrared Sauna vs. Traditional Sauna at a Glance
| Feature | Infrared Sauna | Traditional Sauna |
|---|---|---|
| How it produces heat | Infrared radiant energy | Heats the surrounding air |
| Typical temperature | About 110–135°F (43–57°C) | About 150–195°F (66–91°C) |
| How your body is heated | More directly by infrared radiation | Primarily by hot surrounding air |
| Humidity | Usually low | Usually low, although water can be added to sauna stones in many traditional saunas |
| Sweat response | Sweating at a lower room temperature | Sweating at a higher room temperature |
| Heat sensation | Gentler and more gradual | Hotter and more intense |
| Energy experience | Generally lower operating temperatures | Higher room temperatures |
| Best known for | Comfortable heat therapy and relaxation | Traditional sauna experience and intense heat exposure |
Mayo Clinic explains that the fundamental difference is that a conventional sauna warms the air, while an infrared sauna uses light to warm the body more directly.
What Is a Traditional Sauna?
A traditional sauna, sometimes called a Finnish sauna, uses a heater to raise the temperature of the room.
The heater warms sauna stones and the surrounding air. Your body then absorbs heat from the hot environment.
Traditional saunas commonly operate at approximately 150°F to 195°F (66°C to 91°C), although temperatures vary depending on the sauna design and personal preference. Cleveland Clinic gives a typical range of approximately 150°F to 195°F for traditional saunas.
Traditional saunas can also allow water to be poured over heated stones to create bursts of steam and temporarily increase humidity.
This creates the classic sauna experience familiar from Nordic sauna culture.
How Does a Traditional Sauna Make You Sweat?
The mechanism is relatively straightforward:
-
The sauna heater raises the air temperature.
-
Your skin and body are exposed to the hot air.
-
Your body attempts to regulate its temperature.
-
Blood vessels near the skin dilate.
-
Your heart rate can increase.
-
Your body begins producing sweat to help cool itself.
Sauna bathing therefore creates a form of passive heat exposure that can produce some physiological responses similar to those associated with moderate physical activity.
Research into traditional sauna bathing has found associations between regular sauna use and cardiovascular and other health outcomes, although much of this evidence is observational and should not be interpreted as proof that sauna use alone prevents or treats disease.
What Is an Infrared Sauna?
An infrared sauna works differently.
Instead of primarily heating the surrounding air, infrared heaters emit infrared radiation, which transfers energy directly to your body.
This means an infrared sauna can feel hot and make you sweat without requiring the room to reach the extremely high temperatures found in many traditional saunas.
According to Mayo Clinic, infrared saunas can produce sauna-like effects such as sweating and an increased heart rate at lower temperatures than conventional saunas.
Cleveland Clinic reports typical infrared sauna temperatures of approximately 110°F to 135°F (43°C to 57°C).
That lower temperature is one of the biggest reasons people choose infrared.
Why Does an Infrared Sauna Feel Different?
Imagine sitting in a traditional sauna at 180°F.
The entire room is extremely hot.
Now imagine sitting in an infrared sauna at around 120°F.
The air itself is much cooler, but the infrared panels are delivering radiant heat to your body.
For many people, this creates a more comfortable sauna experience.
This is particularly appealing if you enjoy sweating and relaxation but find the extreme temperatures of a traditional sauna difficult to tolerate.
Infrared vs. Traditional Sauna: Which One Gets Hotter?
Traditional saunas win when it comes to air temperature.
A traditional sauna can reach approximately 150°F–195°F or higher depending on the sauna and operating conditions.
Infrared saunas generally operate at approximately 110°F–135°F.
But temperature alone doesn't tell you everything about the experience.
An infrared sauna can still make you sweat significantly because the infrared energy heats your body without requiring the entire room to reach traditional sauna temperatures.
That's why comparing the two simply by thermometer reading can be misleading.
Does an Infrared Sauna Make You Sweat More?
Not necessarily.
Both types of saunas can produce substantial sweating.
The major difference is how the heat reaches your body.
Traditional sauna:
Heater → hot air → body
Infrared sauna:
Infrared heaters → radiant energy → body
The lower operating temperature of infrared saunas can make the experience more comfortable for people who don't tolerate extreme heat well.
Mayo Clinic specifically notes that infrared saunas can produce sweating and an increased heart rate at lower temperatures than traditional saunas.
Which Sauna Is Better for Relaxation?
For relaxation, there isn't a universal winner.
It largely comes down to personal preference.
Some people love the intense heat of a traditional sauna. Others prefer the gentler warmth of an infrared sauna.
An infrared sauna may be particularly appealing if:
-
You dislike extremely high temperatures.
-
You prefer longer, more comfortable heat sessions.
-
You want a more gradual heat experience.
-
You are installing a sauna in your home.
-
You prefer the modern design of infrared sauna cabins.
Traditional saunas may be preferable if:
-
You love intense heat.
-
You want the classic Finnish sauna experience.
-
You enjoy sauna stones and occasional steam.
-
You prefer a hotter environment.
-
You want a more traditional sauna atmosphere.
Infrared Sauna vs. Traditional Sauna for Muscle Recovery
Heat exposure can be relaxing after physical activity, and many people use saunas as part of their recovery routine.
Infrared saunas are particularly popular among people looking for comfortable heat after workouts because they provide radiant heat without the extremely high air temperatures of a traditional sauna.
However, it's important to distinguish comfort and temporary relief from proven medical treatment.
Medical sources suggest potential benefits of sauna use, but the evidence is not strong enough to claim that infrared saunas cure injuries, dramatically accelerate healing, or replace appropriate medical treatment.
Cleveland Clinic notes potential wellness benefits associated with infrared sauna use, while also emphasizing that more research is needed for many of the health claims made about infrared therapy.
What Does the Research Say About Infrared Saunas?
This is where it's important to separate science from marketing.
Infrared sauna research is promising in several areas, but it is not yet strong enough to support every claim commonly found online.
Mayo Clinic states that studies have explored infrared sauna use in conditions including high blood pressure, heart failure, arthritis, headaches, type 2 diabetes, and other conditions. However, Mayo Clinic also emphasizes that larger and more precise studies are needed to establish clear health benefits.
A systematic review and meta-analysis examining sauna therapy in people with heart failure found short-term improvements in certain cardiac measurements following infrared sauna therapy, but the researchers also concluded that more evidence is needed regarding long-term effects.
In other words:
Infrared sauna research is interesting—but it shouldn't be presented as a miracle cure.
That's an important distinction when evaluating sauna health claims.
Does Infrared Sauna Detox Your Body?
This is one of the biggest myths surrounding infrared saunas.
You will certainly sweat in an infrared sauna.
But sweating does not mean that a sauna is removing large quantities of toxins from your body.
Your body already has sophisticated systems responsible for processing and eliminating waste, including the liver and kidneys.
Sweating's primary biological function is helping regulate body temperature.
Therefore, claims that infrared sauna sessions “detoxify” the body should be treated cautiously.
A strong wellness article should focus on what sauna therapy can realistically provide rather than making unsupported detox claims.
Can Sauna Use Help You Lose Weight?
A sauna session can temporarily reduce your body weight because you lose water through sweating.
But this is not the same as losing body fat.
Once you rehydrate, much of that temporary weight loss returns.
Cleveland Clinic specifically notes that sauna use should not be considered a weight-loss strategy because there isn't clear evidence that sauna bathing causes meaningful fat loss.
If your goal is fat loss, nutrition, resistance training, physical activity, sleep and an appropriate calorie balance remain much more important.
A sauna can be part of a healthy lifestyle, but it shouldn't replace exercise.
Which Sauna Uses Less Heat?
Infrared saunas generally operate at substantially lower room temperatures.
This is one of their biggest practical advantages.
A traditional sauna may require the room to reach temperatures around 150°F–195°F.
An infrared sauna can provide a substantial heat experience at approximately 110°F–135°F.
That lower ambient temperature can make infrared saunas attractive for home users who want the benefits and relaxation associated with sauna bathing without sitting in extremely hot air.
Which Sauna Is More Comfortable?
For many people, infrared wins on comfort.
The lower air temperature means you don't have to tolerate the same level of ambient heat found in a traditional sauna.
This can make infrared particularly attractive for beginners.
However, comfort is subjective.
Someone who loves the intense heat and ritual of a Finnish sauna may find an infrared sauna less satisfying.
The best sauna is therefore not necessarily the one with the highest temperature.
It's the one you can comfortably use and enjoy consistently.
Is Infrared Sauna Better Than Traditional Sauna?
Not necessarily.
Infrared and traditional saunas use different heating methods, but both expose your body to heat.
The biggest practical difference is the temperature and the way heat is delivered.
If you want a traditional, high-temperature sauna experience, a traditional sauna may be the better choice.
If you want a lower-temperature environment with radiant heat and a gentler experience, an infrared sauna may be the better option.
There is currently not enough high-quality evidence to conclude that infrared saunas are universally healthier than traditional saunas.
Mayo Clinic similarly notes that although infrared sauna research has produced promising findings, more precise and larger studies are needed.

Which Sauna Should You Choose?
The right choice depends on your lifestyle and what you expect from your sauna.
Choose an infrared sauna if:
You want a lower-temperature, comfortable sauna experience and don't enjoy extremely hot air.
Choose a traditional sauna if:
You want the classic Finnish sauna experience, high temperatures and intense heat.
Choose either if:
Your primary goal is relaxation, sweating and incorporating heat exposure into a broader wellness routine.
The important thing is consistency, comfort and safe use—not simply choosing the sauna with the highest temperature.
A Final Word on Sauna Safety
Saunas are generally well tolerated by many healthy adults, but heat exposure isn't appropriate for everyone.
Dehydration, dizziness, overheating and low blood pressure can occur, particularly when sessions are excessive or when someone is not adequately hydrated.
A systematic review of regular dry sauna bathing reported generally mild-to-moderate adverse effects in the studies reviewed, including heat discomfort, intolerance and occasional light-headedness, while also documenting that more serious heat-related events can occur.
If you have a cardiovascular condition, are pregnant, take medications that affect blood pressure or fluid balance, or have another medical condition that could make heat exposure risky, speak with a healthcare professional before using a sauna.
And never use a sauna as a replacement for medical treatment.
The Bottom Line
So, what is the difference between an infrared sauna and a regular sauna?
The simplest answer is this:
A traditional sauna heats the air. An infrared sauna uses infrared radiation to heat your body more directly.
Traditional saunas operate at much higher temperatures and provide the classic intense sauna experience.
Infrared saunas operate at lower temperatures and are often easier to tolerate while still producing significant warmth and sweating.
Neither should automatically be considered “better.”
If you love intense heat and the traditional sauna experience, choose a traditional sauna.
If you prefer a gentler environment and lower temperatures, infrared may be the better fit.
The best sauna is ultimately the one that fits your comfort level, lifestyle and wellness goals—and that you can use safely and consistently.
Frequently Asked Questions
Is infrared sauna better than a traditional sauna?
Not necessarily. Infrared and traditional saunas use different heating methods. Infrared saunas operate at lower temperatures, while traditional saunas heat the surrounding air to much higher temperatures. Current research does not establish that infrared saunas are universally superior.
Is an infrared sauna hotter than a regular sauna?
No. Infrared saunas typically operate at substantially lower air temperatures than traditional saunas. Infrared models commonly operate around 110°F–135°F, while traditional saunas are often around 150°F–195°F.
Do infrared saunas make you sweat?
Yes. Infrared saunas can cause substantial sweating even though the surrounding air is cooler than in a traditional sauna.
Does infrared sauna burn fat?
There is not clear evidence that sauna use produces meaningful fat loss. Any immediate drop in weight after a sauna session is primarily related to fluid loss from sweating.
Does infrared sauna detox your body?
Sweating helps regulate body temperature, but claims that infrared saunas dramatically “detox” the body are not strongly supported by high-quality medical evidence.
How long should you stay in a sauna?
There is no single duration that is appropriate for everyone. Start conservatively, pay attention to how you feel, stay hydrated and leave immediately if you become dizzy, weak, nauseated or otherwise unwell.
Which sauna is best for home use?
For many homeowners, infrared saunas are attractive because they operate at lower temperatures and can provide a comfortable heat experience. Traditional saunas are a better choice for people who specifically want the classic high-temperature Finnish sauna experience.
