Our name
Two origins, one purpose
Solen, the Swedish word for sun.
SOLN, Science Of Light and Nature.
Our name holds both: ancient recognition of light's restorative properties and modern understanding of how wavelengths interact with the body. Soln makes wellness technology that bridges the two. Clinical-grade wavelengths, designed for home.
What you'll feel
Built for the body that carries everything
For years, professional-grade wellness technology meant clinical environments and the compromises of shared spaces. Soln exists to collapse that distance, bringing the depth of professional-grade sessions into spaces that feel like your sanctuary. We believe you should not have to choose between precision and comfort.
What's measured
The science behind
The sun delivers infrared and red light wavelengths naturally. Your body recognizes them. Infrared penetrates tissue, you feel it as deep warmth. Red light reaches structures beneath the skin. PEMF creates electromagnetic fields your cells can detect. These wavelengths have been studied in clinical and athletic settings for decades. Soln devices deliver them with precision, calibrated to the ranges researchers have documented.
