What Are Far Infrared Rays?
Far Infrared Rays (FIR) are commonly known as the "Light of Life"—an invisible part of the spectrum of sunlight that has brought life to the Earth. These electromagnetic waves exist between visible light and microwave on the spectrum, with wavelengths ranging from 0.76 microns to 1,000 microns.
Far Infrared Rays specifically range from 4 to 1,000 microns, occupying the longest wavelength portion of the infrared spectrum. Unlike visible light, FIR is not something you can see—but its effects on molecular structures are profound.
The Electromagnetic Spectrum
Visible Light
The narrow band of electromagnetic radiation visible to the human eye, with wavelengths from 0.38 to 0.76 microns.
Near Infrared
Wavelengths from 0.76 to 1.5 microns. Commonly used in remote controls and fiber optic communications.
Mid Infrared
Wavelengths from 1.5 to 4 microns. Used in thermal imaging and industrial heating applications.
Far Infrared (FIR)
Wavelengths from 4 to 1,000 microns. The most biologically active portion of the infrared spectrum, vital for life processes.
Bio-Ceramic Fibers & FIR
Bio-ceramic fibers are the ultimate material for storing and emitting Far Infrared Rays. While all substances on Earth generate some level of FIR, ceramics are uniquely capable of generating them on a stable, continuous basis.
Our Saiseiko ceramics are precision-engineered from a patented blend of over 50 natural minerals, inorganic stone, and clay. This specific composition maximizes FIR emission in the biologically active range, creating a powerful yet passive source of life-enhancing energy.
How FIR Activates Water
Cluster Breakdown
FIR energy penetrates water molecules and breaks apart large molecular clusters into smaller, hexagonal structures that are more easily absorbed by cells.
Negative Ion Generation
The infrared energy shifts water's ionic balance, creating an abundance of negative ions—the same beneficial ions found near waterfalls and ocean waves.
Molecular Resonance
FIR wavelengths resonate with water molecules at their natural frequency, causing gentle vibration that enhances the water's properties and energy state.
