Infrared vs Steam Sauna: Which One Is Right for You?

Infrared and steam saunas both deliver heat therapy, but they do so in very different ways. These differences determine your experience and the benefits you get after each session.

Steam saunas create a hot, humid environment that envelops your body in heated air and moisture, while infrared saunas use light waves to warm your body directly from within, typically in a drier, lower-temperature setting. Neither option is universally “better.” The right choice depends on how you prefer to heat, how intense you want the experience to feel, and what health or relaxation goals you’re aiming for.

In this guide, we’ll break down how each system works, what the experience feels like in real use, and the key differences that matter when deciding which sauna is right for you.

What is an Infrared Sauna?

An infrared sauna is a wood-lined cabin that uses infrared panels to heat your body directly rather than the air around you. The infrared energy penetrates the skin and creates a warming effect from within. As a result, you’ll experience an intense sweat response even though the air temperature is much lower than in a traditional sauna.

Most home infrared saunas operate at 120°F-150°F, compared to the 150°F–195°F range commonly found in traditional Finnish saunas. Because the temperature is lower and you’re warmed directly from within, you can comfortably stay inside for 20–45 minutes, depending on personal preference and heat tolerance.

Infrared saunas use one or more of three infrared wavelengths:

• Near-infrared (NIR): This is the shortest wavelength and is primarily absorbed near the skin’s surface.
• Mid-infrared (MIR): This penetrates deeper into soft tissue and is often associated with increased circulation and relaxation.
• Far-infrared (FIR): This is the most commonly used wavelength in residential infrared saunas, capable of penetrating several centimeters into the body and producing the deep, warming sensation most users associate with infrared therapy.

Many premium models are marketed as full-spectrum infrared saunas, meaning they combine near-, mid-, and far-infrared wavelengths in a single unit. The goal is to provide a broader range of heating effects while allowing users to experience the benefits associated with each part of the infrared spectrum.

How Does an Infrared Sauna Work?

Infrared panels, made from carbon fiber, ceramic, or a combination of both, emit radiant heat in the infrared spectrum. When that light contacts your skin, it’s absorbed and converted to heat within the tissue. This causes your core temperature to rise and triggers a deep sweating response even though the surrounding air remains relatively cool.

Because the heat is delivered directly to the body rather than building up in the air, infrared saunas can operate at lower temperatures while still producing a strong thermal effect. This allows for longer, more comfortable sessions without the intense heat load associated with traditional steam or dry saunas.

Benefits of Infrared Saunas

Regular infrared sauna use produces a cardiovascular response similar to moderate aerobic exercise. As core body temperature rises, your heart rate increases, thereby increasing blood circulation.

Over time, you start to see improvement in your heart health. Research supports this, too. According to a landmark study published in JAMA Internal Medicine, frequent sauna use has been shown to lower the rates of cardiovascular disease and related events. While these studies include both traditional and infrared saunas, they show how important heat therapy is to your well-being.

Other benefits are:

1. It Speeds Muscle Recovery

Far-infrared sauna wavelength reaches around 4–5cm into muscle tissue. At that depth, they increase blood flow through fatigued muscles and speed up the removal of waste products like lactate, which build up after training and cause soreness. This is why athletes and fitness enthusiasts use infrared saunas after training sessions.

2. It provides relief from chronic pain

Infrared heat penetrates deeper into muscles and joints, which can help ease long-term discomfort associated with conditions such as arthritis and fibromyalgia. This deeper warming effect improves blood flow to affected areas, especially tissues that are inflamed or not receiving adequate circulation.

At the same time, the heat directly influences pain receptors in muscles and connective tissue, which can reduce perceived pain levels. With consistent use, this combination of improved circulation and thermal relief may also support better mobility and overall joint comfort.

3. It boosts collagen production

NIR light has been shown to stimulate the skin cells responsible for producing collagen and elastin. For context, collagen and elastin are the structural proteins that give skin its firmness, elasticity, and ability to maintain shape after stretching or movement. As we age, the natural production of these proteins slows, contributing to fine lines and a thinner skin texture. NIR light also helps to clear the skin pores and keep the skin hydrated.

4. It improves sleep quality

Heat exposure shifts the body into its rest-and-repair state and reduces cortisol — the primary stress hormone. After a session ends, your core body temperature gradually drops, and that cooling curve is one of the brain’s key signals to initiate sleep.

Pros of Infrared Saunas

• Lower operating temperature (120–150°F) makes sessions more accessible for people with heat sensitivity
• Deep tissue penetration at 4–5cm supports muscle recovery and circulation more directly than surface-level heat
• Easy to install
• Consumes less energy compared to steam rooms
• Low maintenance

Cons of Infrared Saunas

• Full-spectrum units with near- and mid-infrared panels cost more than basic far-infrared models
• Low-quality or cheap units can emit high levels of electromagnetic fields (EMFs)
• Lacks löyly, the authentic Finnish sauna experience of a traditional sauna

What is a Steam Sauna?

A steam sauna, more commonly called a steam room, is a sealed, tiled enclosure where a steam generator converts water into vapor and fills the space with hot, moist air. The heat reaches you from the outside in, carried by saturated air surrounding your body.

Ideally, steam rooms operate between 150°F and 195°F, with humidity levels that can reach 100%. The sessions are also shorter, usually 10 to 20 minutes, because of the intense heat and high humidity.

How Does a Steam Room Work?

A steam room works by using a special steam generator installed outside the enclosure. The generator heats water and pushes steam through a pipe into the room. The room itself needs to be fully sealed and waterproofed with non-porous materials like tile or stone to prevent steam from escaping.

Since the air is completely saturated with moisture, the steam condenses to water as it touches your skin. In this process, heat is transferred directly into the body to create a rapid and intense warming effect.

Benefits of Steam Saunas

Here are the benefits of a steam room:

1. It Opens Your Airways and Eases Congestion

Breathing in warm, moist air at near-100% humidity loosens phlegm and reduces inflammation in the nasal passages and airways. If you’re dealing with sinus congestion, bronchitis, or any other respiratory discomfort, staying in a steam room can help clear it.

2. It Hydrates and Refreshes Your Skin

A steam room helps your skin in a very direct way. The heat and humidity open your pores, soften the skin’s outer layer, and keep it naturally moist throughout the session. As the warm air surrounds your body, blood flow to the skin increases, which is why you often step out looking flushed and refreshed.

It also helps loosen dirt and buildup in the pores, so your skin feels cleaner and more receptive to washing afterward. Most of the hydration effect is temporary and happens at the surface, but with regular use, the improved circulation can contribute to a more even tone and texture over time.

3. It Relaxes Tight Muscles

The heat from a steam room gently warms the body and helps relax tight muscles, especially in common tense areas like the neck, shoulders, and upper back. Also, the high humidity allows heat to penetrate soft tissues, which helps loosen tension in tight areas.

4. It Reduces Stress and Helps You Sleep

Like infrared heat, steam helps shift the body into a rest-and-recovery state by activating the parasympathetic nervous system and lowering cortisol levels, the body’s main stress hormone.

The warm, enclosed environment also creates a calming sensory effect that many people find more immersive than dry heat. After a session, your core body temperature slowly drops, and this cooling process signals the brain that it is time to rest.

This is why steam rooms can help wind down at night, especially for people who struggle to relax or fall asleep easily.

Pros of Steam Saunas

• Near-100% humidity provides real respiratory relief
• The humid environment hydrates skin and improves its appearance
• Delivers a classic spa experience in the comfort of your home
• The high heat flushes toxins from skin pores

Cons of Steam Saunas

• Requires full waterproofing, a steam generator, a water supply, and drainage
• Requires ongoing maintenance
• The high-heat environment can feel suffocating, especially for newbies starting heat therapy

Difference Between Infrared and Steam Sauna

The difference between infrared and steam saunas comes down to the heat source itself.

Infrared saunas use infrared light to warm your body directly rather than heating the surrounding air. The heat penetrates 4–5cm into muscles and tissues, which is why sessions feel more intense at a lower ambient temperature than in a traditional steam environment.

Steam rooms, however, operate on the opposite principle. A steam generator converts water into vapor, filling a sealed enclosure with humid, moist air that raises ambient temperature and envelops the body from the outside in.

Other differences are:

1. Heat Source

Infrared saunas use carbon fiber or ceramic panels to emit radiant heat that targets your body directly. Instead of heating the surrounding air, infrared energy passes through it and is absorbed by your skin and tissues. This means the cabin itself can stay cool while your body warms from within.

Steam rooms, on the other hand, rely on a steam generator to fill a fully sealed enclosure with hot, moisture-laden air. In this case, it is not direct radiation but the surrounding saturated air that transfers heat to your body. Because the air holds so much moisture, it limits your ability to cool down through sweating, which makes the heat feel more intense.

Verdict:

Infrared delivers direct, lower-ambient heat, while steam creates a more intense, enveloping heat through humid air.

2. Operating Temperature

Infrared saunas run between 120°F and 150°F. Because the air itself is not extremely hot, the environment feels more manageable for longer sessions.

Steam rooms operate at higher temperatures, usually between 150°F and 195°F. With humidity close to 100%, the body loses its ability to cool itself through sweat evaporation. As a result, even a steam room at the lower end of that range can feel more intense than an infrared cabin at the same temperature.

Verdict:

Infrared is generally easier to tolerate for heat-sensitive users and allows longer sessions. Steam feels more intense, which is why most people stay in for shorter periods.

3. Humidity Level

Infrared saunas operate in a near-dry environment. There is little to no added moisture in the air, so the heat feels dry and breathable throughout the session.

Steam rooms sit at the opposite extreme, often reaching close to 100% relative humidity. The air becomes fully saturated with moisture, and every surface, including your skin, is surrounded by warm vapor. This high humidity is what makes steam feel dense, heavy, and immersive.

Verdict:

Dry infrared heat tends to suit people who prefer easier breathing or have respiratory sensitivity. A steam sauna is better suited for those who want the benefits of high humidity, such as skin hydration and airway moisture.

4. Heat Penetration

Far-infrared wavelengths reach 4–5cm below the skin — into muscle tissue and connective structures. Steam works at the surface. It warms the skin and superficial tissues, but doesn’t reach the depth that infrared does.

Verdict:

Infrared wins for muscle recovery, deep tissue effects, and chronic pain. Steam’s surface warmth is useful for relieving tension and hydrating the skin.

5. Session Length

Infrared sauna sessions last 20–45 minutes, while steam room sessions are usually limited to 10–20 minutes.

Verdict:

If cumulative heat exposure matters, for cardiovascular benefits or recovery, go for infrared saunas.

6. Respiratory Comfort

Infrared saunas use dry heat, which many people find easier to tolerate, especially if they are sensitive to humid environments.

Steam rooms, on the other hand, fill the air with warm moisture that can help loosen mucus, ease congestion, and provide temporary relief from cold or sinus symptoms.

Verdict:

Choose an infrared sauna if you prefer a dry environment or find high humidity uncomfortable. Choose a steam room if your primary goal is temporary relief from nasal congestion, sinus pressure, or dry airways. The better option depends largely on how your respiratory system responds to humidity.

Installation Complexity

Infrared saunas are easy to install. Most models arrive as prefabricated units that can be assembled in a few hours. Smaller units often plug into a standard 120V outlet, while larger models may require a dedicated 240V electrical circuit. You can install them in a spare room, basement, garage, or other unused indoor space.

Steam rooms, however, require a much more involved installation process. In addition to the steam generator itself, you’ll need a fully waterproof and vapor-sealed enclosure, plumbing for water supply and drainage, proper ventilation, and electrical connections. Because moisture management is critical, the space must be built or remodeled specifically for steam use.

Verdict:

An infrared sauna is easier and less expensive to install. A steam room is a major renovation project that usually requires professional contractors experienced in waterproofing, plumbing, and wet-room construction.

Cost

Home infrared units start around $1,000 for entry-level far-infrared models and reach $4,500+ for full-spectrum multi-person cabins. Steam room installation runs $2,500–$6,000+ installed and can cost more if your bathroom needs modifications.

Verdict:

Infrared offers a lower entry point, with no installation labor, for most home setups. The total cost of a steam sauna depends heavily on what the existing space can accommodate.

Who Should Choose an Infrared Sauna

Infrared is the right fit if:

• Muscle recovery and post-training relief are a priority
• You want cardiovascular and circulation benefits from regular use
• You find high heat or high humidity hard to tolerate
• You want something you can use several times a week without friction
• You’re setting up at home and don’t want a major renovation
• You want to explore full-spectrum wavelengths for skin health and broader wellness coverage

Who Should Choose a Steam Sauna

Steam is the right fit if:

• Respiratory relief is your primary goal
• You want immediate skin hydration and the classic wet-heat experience
• You value the sensory ritual of traditional sauna bathing
• You’re building a dedicated steam space in a bathroom with the right infrastructure
• You find dry heat uncomfortable and tolerate moist heat better

The Bottom Line

Both infrared saunas and steam rooms deliver health benefits. The choice between the two comes down to your personal preferences and what you’re looking to get.

If your main goals are muscle recovery, cardiovascular health, or relief from chronic pain, an infrared sauna is the way to go. The dry air is comfortable to breathe, and you don’t need any major renovation to get started.

However, the sauna room works well for respiratory relief, skin hydration, or the traditional wet-heat experience.

And if you want both? They work well together. Most buyers use an infrared sauna as their everyday recovery tool and add a steam shower for the humidity benefits.

FAQs

Is an infrared sauna better than a steam room?

Neither is universally better. Infrared is good for cardiovascular health, deep muscle recovery, and regular low-intensity use. A steam sauna provides respiratory relief, skin hydration, and an immersive wet-heat experience. Your goals determine which one delivers more value.

Can I use an infrared sauna if I have asthma?

Infrared is generally better tolerated by people with respiratory sensitivities than steam. The dry air environment doesn’t aggravate airways the way high humidity can. That said, consult your doctor before using either type if you have a respiratory condition.

How often should I use each?

For infrared, three to four 30–45-minute sessions per week are a great place to start. For steam, you can start with 15-20 minutes per session. Overall, the ideal range depends on your heat tolerance.

Which is easier to install at home?

Infrared is easier to install. Units like the Dynamic Serena 2 Person Full Spectrum sauna come as plug-and-play models, so you don’t need to build the sauna from scratch. Steam rooms, however, require a sealed enclosure, steam generator, water supply, and drainage.
