What Is a Full Spectrum Sauna?
A full spectrum sauna combines multiple infrared wavelengths into a single sauna system.
Most full spectrum saunas include:
- Near infrared (NIR)
- Mid infrared (MIR)
- Far infrared (FIR)
In practical terms, most buyers think about full spectrum technology this way:
Far infrared provides the heat.
Near infrared provides the light therapy.
A full spectrum sauna gives you both.
Why Were Full Spectrum Saunas Developed?
The first generation of infrared saunas focused almost entirely on far infrared heat.
People loved the comfortable temperatures, relaxing sessions, and wellness benefits associated with infrared sauna use.
As research into photobiomodulation and near infrared light therapy expanded, manufacturers began adding near infrared technology to their sauna designs.
The result became what we now call a full spectrum sauna.
Today, full spectrum systems are among the most popular premium infrared sauna options available.
Understanding the Difference Between Near Infrared and Far Infrared
Far Infrared
Far infrared is responsible for most of the heat people associate with infrared saunas.
Far infrared is commonly used for:
- Relaxation
- Recovery
- Healthy sweating
- Daily wellness routines
- Cardiovascular wellness support
If you’ve used an infrared sauna before, you’ve likely experienced far infrared heat.
Near Infrared
Near infrared is much closer to visible light on the electromagnetic spectrum.
Unlike far infrared, near infrared is often discussed in relation to photobiomodulation.
Researchers continue studying near infrared light and its effects on:
- Skin health
- Tissue support
- Recovery
- Cellular function
Near infrared produces less heat than far infrared and serves a different purpose inside a full spectrum sauna.

Full Spectrum Sauna vs Far Infrared Sauna
This is the comparison most buyers care about.
Far Infrared Sauna
A far infrared sauna primarily focuses on heat therapy.
Best for:
- Relaxation
- Recovery
- Healthy sweating
- Daily sauna use
- Lower budgets
Full Spectrum Sauna
A full spectrum sauna combines far infrared heat with near infrared therapy.
Best for:
- Relaxation
- Recovery
- Healthy sweating
- Near infrared therapy
- Photobiomodulation applications
- Maximum flexibility
The heat experience is similar.
The difference is the addition of near infrared technology.
Is a Full Spectrum Sauna Worth the Extra Cost?
That depends on your goals.
If your primary objective is relaxation, recovery, sweating, and enjoying the traditional benefits of infrared heat therapy, a far infrared sauna may be all you need.
If you’re specifically interested in near infrared therapy and photobiomodulation, a full spectrum sauna may be worth the upgrade.
Many buyers choose full spectrum systems because they want access to both technologies in a single sauna.
Full Spectrum vs Hybrid Sauna
These two categories are often confused.
Full Spectrum Sauna
Includes:
- Near infrared
- Mid infrared
- Far infrared
Hybrid Sauna
Includes:
- Traditional sauna heating
- Steam capability
- Near infrared
- Far infrared
Hybrid saunas are designed for people who want both traditional sauna experiences and infrared technologies in a single unit.

Who Should Consider a Full Spectrum Sauna?
A full spectrum sauna may be a good fit for people who:
- Already know they want an infrared sauna
- Are interested in near infrared therapy
- Want access to multiple infrared wavelengths
- Want maximum flexibility from a single sauna
For many homeowners, a full spectrum sauna represents the most complete infrared sauna experience available.
What This Means for Sauna Buyers
The biggest difference between a far infrared sauna and a full spectrum sauna isn’t the heat.
It’s the addition of near infrared technology.
If your goal is simply enjoying the benefits of infrared heat, a far infrared sauna can be an excellent choice.
If you also want access to near infrared therapy and photobiomodulation applications, a full spectrum sauna may be worth considering.
The right choice depends on your goals, budget, and how you plan to use your sauna.
