Infrared saunas(Infrared Radiation Saunas)have become extremely popular in recent years, thanks to their therapeutic benefits and ease of use. If you're considering investing in such a sauna, you may have come across the terms FIR Sauna (Far Infrared) and IR Sauna (Infrared). But what is the difference between them, and which one is the best choice for you? Let’s take a closer look.
What Is an Infrared Sauna (IR Sauna)?
A IR Sauna (Infrared) uses infrared radiation to heat your body. Unlike traditional saunas that heat the air, infrared saunas heat the body directly, inducing sweating at lower temperatures. The spectrum of infrared radiation is divided into three types:
- Near-Infrared Heating (NIR – Near Infrared): 0,7–1,4 μm
- Mid-Infrared Heating (MIR – Mid Infrared): 1,4–3 μm
- Far-Infrared Heating (FIR – Far Infrared): 3–1000 μm
Each sauna may use one or more of these wavelengths, but the FIR sauna focuses exclusively on far-infrared radiation.
What Is an FIR Sauna?
A FIR (Far Infrared) The sauna uses far-infrared radiation to heat your body. This wavelength is particularly beneficial as it is compatible with the heat emitted by the human body itself. FIR penetrates deeply into the body (about 4-5 centimeters), warming the tissues and organs instead of just heating the surface of the skin.
- Operating Temperature: Lower temperatures, 40–60°C.
- Penetration: Deep heating of the tissues and muscles.
- Result: Intense detoxification, improved blood circulation, and relief from chronic pain.
What Are the Differences Between FIR and IR Saunas?
IR saunas generally include the full spectrum of infrared radiation (NIR, MIR, and FIR). On the other hand, FIR saunas, the type offered by our company, FUJIA, focus exclusively on the far-infrared wavelength. Let’s take a closer look at their differences:
| Characteristic | FIR Sauna | IR Sauna (NIR/MIR) |
| Radiation Range | Far-Infrared (FIR) | Near-Infrared (NIR), Mid-Infrared (MIR) |
| Penetration Depth | Penetrates deeply into the tissues | Limited to the surface |
| Temperature | 40–60°C | 50–70°C |
| Thermal Effect | Deep sweating and detoxification | Quick heating of the skin |
| Focus | Therapeutic heating for the tissues | Relaxation and surface heating |
What Are the Benefits of the FIR Sauna?
The FIR sauna offers unique benefits due to the deep penetration of FIR radiation. These include:
- Deep detoxification: Helps the body eliminate heavy metals, toxins, and chemicals.
- Improved circulation: The heat increases blood flow and promotes the natural healing of tissues.
- Pain relief: It is particularly effective for people with arthritis, muscle pain, or chronic inflammations.
- Lower temperatures: Ideal for those who struggle to tolerate the high temperatures of traditional saunas.
- Energy efficiency: It requires less energy to operate, making it environmentally friendly.
Which Sauna is Suitable for You?
- FIR Sauna: Choose it if you want lower temperatures, deep detoxification, and therapeutic results. It is ideal for people with chronic pain, stress, or those seeking a relaxing experience.
- IR Sauna (NIR/MIR): Suitable for quicker heating or surface treatments, such as skin rejuvenation or combined with LED light therapy.
Conclusion:
The choice between FIR and IR saunas depends on your needs and preferences. The FIR sauna is specialized for deep therapy and detoxification, while the IR offers more flexible options for surface heating. If you are looking for an upgraded wellness experience, FIR is often the best choice!
