Near vs Far-Infrared Sauna: What's the Difference?

Infrared saunas create heat out of light, but not all are created equal. If you're considering getting a portable sauna or one for your home, you might have come across near-infrared and far-infrared options.¹

Near vs far essentially tells you where the infrared wavelengths fall on the spectrum of light. But there are significant differences in therapeutic benefits, how each feels, temperatures, and safety considerations.

Let's discuss near vs far-infrared saunas in detail so you can pick the right one for your health needs, preferences, and wellness goals.

How Infrared Saunas Work

Infrared saunas use infrared lamps to generate energy (heat) through electromagnetic radiation. The lamps emit warm, invisible light that penetrates the skin and raises the body's core temperature.

Unlike traditional saunas, which use stoves and stones to heat the small enclosed area, an infrared sauna doesn't directly heat the air in the space. By warming the body directly, it creates a gentle heat-stress response at a lower temperature to support circulation, relaxation, and recovery.² Learn more about infrared saunas vs traditional saunas in our blog.

When comparing an infrared sauna vs steam room, the key difference is that infrared warms the body from the inside out, while steam rooms heat the air and add moisture. Both can provide relaxation, but the experience and benefits differ

Near-Infrared (NIR)

Near-infrared (NIR) saunas emit shorter—or closer—wavelengths of light, usually between 700 and 1,400 nanometers (nm). Since the light doesn't go as far, penetrating just a few millimeters into the skin, the therapeutic benefits are mostly surface-level.³

For example, some people choose a near-infrared sauna for acne because of its skin-rejuvenating and healing properties.

Far-Infrared (FIR)

Far-infrared (FIR) saunas emit longer wavelengths of light that can travel a bit farther than NIR. At 3,000 to 10,000 nanometers, the light can penetrate deeper—sometimes up to 1.5 inches—to warm muscles, tissues, and joints within the body.⁴

The experience may be more intense, possibly with quickened breathing and more sweating, but the therapeutic effects of NIR saunas can be more noticeable and far-reaching.⁵

Temperatures & Environment

Both types of infrared saunas run cooler than traditional saunas since the light doesn't directly heat the air. However, the temperature and overall feel of NIR and FIR saunas are often still distinct.

Typical NIR Temps

Near-infrared temperatures typically range from 104 to 149 °F (or 40 to 65 °C). They have lower humidity than FIR saunas and can be more comfortable for heat-sensitive users. This may be a safer option for people with health conditions that restrict heat exposure.

Typical FIR Temps

Far-infrared saunas are a bit warmer, with temperatures usually ranging from 131 to 167 °F (or 55 to 75 °C). Even in a dry cabin, FIR light can deliver deeper, whole-body warmth with air temps most users find manageable—and often still more comfortable than traditional saunas.⁶

Key Benefits Compared

Now, let's look at the key benefits of a far-infrared vs near-infrared sauna. The choice ultimately comes down to whether you want surface-level or deeper, systemic effects.⁷

NIR Sauna Benefits

Since the light doesn't go as deep, NIR saunas primarily offer skin benefits. This includes supporting collagen production, promoting external healing, and encouraging cell turnover. The result might be more elastic skin, improved skin tone, and less visible fine lines.⁸ Check out our blog to learn more about infrared sauna skin benefits.

Depending on the wavelength, you might also get targeted relief from shallow aches with NIR.

FIR Sauna Benefits

FIR light goes much deeper to offer whole-body therapeutic benefits. It can stimulate detoxification and help with weight management through sweating. Some people report loosened muscles, relief from joint pain, and stress reduction.⁹ Sitting in a far-infrared sauna can even elevate your heart rate and boost circulation for exercise-like cardiovascular effects.¹⁰

Mid-Infrared (MIR): The Middle Ground

There's also mid-infrared (MIR) electromagnetic light therapy. With wavelengths ranging from roughly 1,400 to 3,000 nanometers, this option sits right between NIR and FIR in terms of heat generation and how deeply it penetrates.

While a mid-infrared sauna may not offer effects as intense as far-infrareds, it might support blood circulation and reduce inflammation in soft tissue.¹¹

NIR vs FIR Sauna Safety & Practical Considerations

Beyond the skin and health benefits, think about what it means to purchase a NIR or FIR sauna, set it up in your home, and use it on a regular basis. Here are some points to consider:

• EMF exposure – NIR has the lowest exposure to electromagnetic fields (EMF). Modern NIR cabins are slightly higher but still designed for low EMF at safe levels, often between zero and 3 milligauss (mG).⁴
• Safety and smart use – Before and during sauna sessions, hydrate well with plenty of water. How often should you use an infrared sauna? Start with just a few minutes on a lower temperature setting, and gradually work your way up to longer daily sessions. If you're unwell or have a condition that makes heat exposure dangerous, skip it. (When in doubt, check with a healthcare provider.)
• Space and installation – An FIR sauna often comes as an enclosed cabin, so you'll need dedicated floor space. You can also get a sauna tent, which can be set up as needed and stored when it's not in use. NIR sauna blankets and wraps are more portable.
• Cost and ownership – Near-infrared products are generally more budget-friendly. FIR cabins are more of an investment but give you the enclosed sauna experience. Both types from Lifepro are backed by lifetime warranties.

Which One Is Right for You?

When deciding between a near-infrared or far-infrared sauna, match the therapeutic effects and overall benefits to your lifestyle and wellness priorities.

Who Should Choose Near-Infrared Saunas

Near-infrared saunas can be great for beginners and anyone wanting to save money while exploring the benefits of electromagnetic radiation. NIR products are a stellar option for those looking for skin rejuvenation and surface-level healing, as well as people who prefer mild ambient warmth to more intense heat and sweating.¹²

Who Should Choose Far-Infrared Saunas

Far-infrared saunas are an excellent choice for folks looking for deeper relief from muscle aches, stiff joints, or chronic pain and inflammation.¹³ If you're drawn to sweat-inducing detox sessions and cardio-like benefits, an NIR unit might be the way to go.¹⁴

Consider a Full-Spectrum Sauna

A full-spectrum sauna can offer the best of all worlds. This type of premium cabin can be set to emit a wide spectrum of wavelengths, offering NIR, MIR, and FIR benefits.

If you and another household member have different goals or preferences, a full-spectrum design might be a good compromise. This versatile infrared sauna can promote skin rejuvenation, healing, detoxification, reduced inflammation, and whole-body relaxation.¹⁵
