Saunas have been used for centuries as a tool for relaxation, recovery, and overall well-being. Today, two distinct types dominate the wellness space: infrared saunas and traditional saunas. Both offer meaningful benefits, but they work in fundamentally different ways — and the right choice depends on your goals, lifestyle, and preferences.
This guide breaks down everything you need to know so you can make an informed decision.
How Traditional Saunas Work
Traditional saunas — sometimes called Finnish saunas or steam saunas — heat the air around you using a stove or heater loaded with rocks. The rocks absorb and radiate heat, raising the ambient air temperature to anywhere between 150°F and 195°F (65°C–90°C). When water is poured over the rocks, it creates a burst of steam that intensifies the humidity and the sensation of heat.
Your body responds to this hot environment by sweating heavily, increasing circulation, and working to regulate its core temperature. The experience is immersive and intense — a hallmark of traditional sauna culture that has endured for generations.
How Infrared Saunas Work
Infrared saunas use infrared light panels to emit radiant heat that is absorbed directly by the body, rather than heating the surrounding air. This means the cabin itself stays at a much lower ambient temperature — typically between 120°F and 150°F (49°C–65°C) — while infrared heat is absorbed directly by the body, creating a deep, comfortable warming sensation at lower ambient temperatures.
There are three types of infrared wavelengths: near, mid, and far infrared. Most home infrared saunas use far-infrared technology, which is well-suited for deep tissue warmth and a gentler overall experience.
Key Differences at a Glance
Understanding the practical differences between the two can help you determine which fits your routine best.
Heat Type
Traditional saunas heat the air; infrared saunas heat the body directly through radiant light.
Temperature Range
Traditional saunas run hotter — 150°F to 195°F — while infrared saunas operate between 120°F and 150°F.
Warm-Up Time
Traditional saunas typically take 30–45 minutes to reach optimal temperature. Infrared saunas are ready in 10–15 minutes.
Experience
Traditional saunas deliver a more intense, enveloping heat with optional steam. Infrared saunas offer a milder ambient environment with a deeper, more penetrating warmth.
Installation
Traditional saunas often require dedicated ventilation, drainage, and electrical work. Infrared saunas are generally easier to install and can often plug into a standard outlet.
Energy Use
Infrared saunas tend to be more energy-efficient due to lower operating temperatures and faster heat-up times.
The Wellness Benefits of Each
Both sauna types are widely used to support recovery, relaxation, and general wellness — and both have dedicated followings for good reason.
Traditional Sauna Benefits
The intense heat of a traditional sauna promotes deep sweating and a strong cardiovascular response. Many users find the experience profoundly relaxing after physical exertion, and the ritual of heating the rocks and adding steam adds a sensory dimension that's hard to replicate. Traditional saunas are also a social experience in many cultures — designed to be shared.
Infrared Sauna Benefits
Infrared saunas are often favored for their gentler heat profile, which makes longer sessions more comfortable for many people. The direct absorption of infrared heat is associated with muscle relaxation and a sense of deep, sustained warmth. Because the ambient temperature is lower, infrared saunas can feel more accessible — especially for those who find traditional sauna heat overwhelming.
Both types support post-workout recovery, stress relief, and the kind of intentional downtime that modern wellness routines are built around.
Installation and Space Considerations
Traditional saunas require more planning. They need proper ventilation, moisture-resistant construction, and often a dedicated electrical circuit. They're a longer-term investment in your space — but when done right, they become a defining feature of a home wellness setup.
Infrared saunas are more flexible. Many models are designed for straightforward home installation, with plug-and-play electrical requirements and modular construction. They're a strong option if you want a premium sauna experience without a major renovation.
Energy Efficiency
If energy consumption is a consideration, infrared saunas have a clear advantage. Their lower operating temperatures and faster warm-up times mean they use significantly less electricity per session than a traditional sauna running at full heat. Over time, this difference adds up — both in cost and environmental footprint.
Which Sauna Is Right for You?
There's no universal answer — the best sauna is the one that fits your life.
A traditional sauna may be the right choice if:
- You prefer an intense, high-heat experience
- You enjoy the ritual of steam and the social dimension of sauna culture
- You're building a dedicated wellness space and want a permanent installation
- You love the authentic, time-tested sauna experience
An infrared sauna may be the right choice if:
- You prefer a gentler heat with a deep, comfortable warming sensation
- You want faster warm-up times and lower energy costs
- You're looking for a more flexible installation with fewer infrastructure requirements
- You want to use your sauna frequently and for longer sessions
