EMF in Wellness Devices: What's Real, What's Marketing
Sauna blankets, PEMF mats, and panels all produce electromagnetic fields. What the published limits are and how our tested devices compare.
Wavelength Science Coming Soon
630nm vs 660nm vs 850nm vs 940nm: Does the Difference Matter?
Each wavelength penetrates tissue differently and activates different chromophores. Here's what the research actually says about which combinations produce better outcomes.
Infrared Sauna Coming Soon
Infrared Sauna Science: Far-Infrared vs. Near-Infrared vs. Full Spectrum
Sauna blankets use FIR (far-infrared) heat, not the photobiomodulation wavelengths used in panels and masks. Here's the actual mechanism — and why they still work.
