When exploring sauna accessories or functional materials, you may encounter the term "Matorin Stone." In reality, this term often refers to Tourmaline (known as "碧玺" in Chinese), a natural mineral widely used in health and wellness fields. Due to regional pronunciation variations or translation nuances, "Tourmaline" is sometimes colloquially called "Matorin Stone" in certain contexts, especially in sauna-related discussions. This article will clarify its true identity, mineral properties, and specific applications in saunas.
1. The True Identity of "Matorin Stone": Tourmaline Mineral
From a mineralogical perspective, there is no independent classification of "Matorin Stone." It is essentially a common name for Tourmaline, a boron-containing silicate mineral with complex compositions. Recognized by the National Gems and Jewelry Technology Administrative Center, Tourmaline is a precious gemstone with both aesthetic and functional value, mainly produced in Brazil, Sri Lanka, and other regions. Its key characteristics relevant to saunas include:
-
Permanent Electrode Property: Tourmaline is one of the few natural minerals with a permanent electric charge. Even without external power supply, it can generate微弱 currents (similar to the human bioelectricity), which helps in regulating the surrounding electromagnetic environment.
-
Far-Infrared Emission: When heated (such as in sauna environments), Tourmaline emits far-infrared rays with wavelengths of 4-14μm. This wavelength range is often called the "life light" because it can penetrate the human body's subcutaneous tissue, promoting blood circulation and metabolism.
-
Negative Ion Generation: Tourmaline can release negative oxygen ions, which are beneficial for improving air quality. In enclosed sauna spaces, this helps reduce the stuffiness caused by high temperatures and enhances breathing comfort.
2. The Role of Tourmaline ("Matorin Stone") in Saunas
In sauna design and use, Tourmaline is typically processed into small stones, ceramic plates, or embedded in sauna benches. Its applications leverage its thermal and electromagnetic properties to enhance the sauna experience and potential wellness effects:
Enhanced Heat Penetration: Compared to traditional lava rocks, Tourmaline's far-infrared emission allows heat to act more deeply on the body. Instead of just heating the skin surface, it promotes internal warmth, making the sweating process more efficient and helping to relieve muscle soreness.
Air Quality Improvement: The negative ions released by Tourmaline counteract the positive ions generated by high-temperature heating equipment, reducing dryness and stuffiness in the sauna. This is particularly beneficial for people with sensitive respiratory systems.
Gentle Bioelectric Regulation: The weak current of Tourmaline is compatible with the human body's bioelectric field, which may help stabilize the nervous system and reduce fatigue during sauna sessions.
3. Usage Notes for Tourmaline in Saunas
To maximize the benefits of Tourmaline and ensure safety, the following points should be noted when using it in saunas:
-
Proper Heating Control: Tourmaline should be heated gradually along with the sauna to avoid thermal shock and cracking. The ideal working temperature ranges from 60°C to 80°C, which aligns with the standard temperature of most saunas.
-
Regular Cleaning: After use, wipe the Tourmaline stones or plates with a dry cloth to remove sweat and dust. Avoid using chemical cleaners that may damage the mineral surface and reduce its functional properties.
-
Complementary Use with Humidity: While Tourmaline helps improve air quality, it does not replace proper sauna humidity control. Spraying适量 water on the stones (including Tourmaline) can enhance the steam effect and prevent excessive dryness.
-
Safety Precautions: Tourmaline itself is non-toxic and safe, but individuals with pacemakers or other electronic medical devices should consult a doctor before using Tourmaline-equipped saunas, as the weak electromagnetic field may interfere with equipment operation.
4. Distinguishing Tourmaline from Other Sauna Stones
In sauna settings, Tourmaline is often compared with traditional lava rocks and jade stones. Here’s a brief comparison to help you understand its unique value:

In conclusion, "Matorin Stone" in saunas is essentially Tourmaline, a mineral that combines aesthetic and functional properties. Its ability to emit far-infrared rays and negative ions adds unique wellness dimensions to the traditional sauna experience. By using and maintaining it properly, you can fully leverage its benefits while enjoying a safe and comfortable sauna session. For those planning to install a home sauna (as discussed in the previous guide on bathroom sauna placement), incorporating Tourmaline elements can be a valuable upgrade to enhance both comfort and functionality.
