Low EMF Full Spectrum Infrared Science
Low EMF Full Spectrum Infrared Science
Full-Spectrum Infrared Technology – The Science of Total-Body Wellness
Our sauna is equipped with advanced full-spectrum infrared heating, delivering a complete range of wavelengths: Near, Mid, and Far Infrared (NIR, MIR, FIR). Each spectrum penetrates the body at different depths, unlocking unique therapeutic effects that work together to transform your health and well-being.
🔴 Near Infrared (NIR) – Surface-Level Cellular Support
Near infrared penetrates the skin surface at a depth of approximately 0.1 to 0.3 mm, within the wavelength range of 700 to 1,400 nanometers. It helps stimulate collagen production, supports cell regeneration and tissue repair, improves skin tone and elasticity, and contributes to enhanced immune function through light therapy. This spectrum is ideal for users looking to boost skin health, accelerate healing, and strengthen the body’s natural defenses.
🟠 Mid Infrared (MIR) – Circulation & Pain Relief
Mid infrared reaches into soft tissue and muscle layers at a depth of around 0.3 to 1.5 mm, with wavelengths ranging from 1,400 to 3,000 nanometers. This level of infrared is known to improve blood circulation, reduce inflammation, alleviate joint and muscle pain, and help release built-up tension. It supports flexibility and aids recovery after physical activity, making it an excellent choice for athletes and anyone with chronic aches or stiffness.
🔵 Far Infrared (FIR) – Deep Detoxification & Relaxation
Far infrared penetrates the deepest—up to 5 cm into the body—targeting muscles, organs, and deep tissue. Operating within the 3,000 to 10,000 nanometer wavelength range, FIR promotes deep sweating to help flush toxins, induces full-body relaxation, and stimulates the metabolism to support weight management. It can also help reduce blood pressure and support cardiovascular health, offering a comprehensive detox and wellness experience.
🧠 Why Full-Spectrum Matters
While many infrared saunas only use far-infrared heating, our full-spectrum design gives you access to the complete range of benefits. You get skin rejuvenation, muscle and joint relief, and full-body detox—all in a single session. It’s like combining three therapeutic tools into one modern wellness system

Long Lasting Carbonised Wood
Carbonised wood is wood that has undergone a heat treatment process, which enhances its durability, resistance to moisture, and ability to withstand outdoor elements. This process gives the wood a sleek, dark, charcoal-like appearance, adding a luxurious and modern aesthetic to saunas. Carbonized wood is ideal for saunas as it is less prone to warping, cracking, and decay, making it both visually appealing and long-lasting in various weather conditions.
Low EMF Full Spectrum
Refers to heating technology used in saunas that delivers the entire range of infrared light (near, mid, and far infrared) while minimizing exposure to electromagnetic fields (EMF). This ensures a more therapeutic experience with benefits like deeper tissue penetration, enhanced detoxification, improved circulation, and muscle recovery. The "low EMF" aspect means the sauna operates with minimal electromagnetic emissions, making it safer for prolonged use by reducing potential health risks associated with high EMF exposure.
