Overview
Sunlighten is an infrared sauna brand. Its official site states that for 25 years Sunlighten has studied how different wavelengths of infrared light interact with the body and engineered its saunas around what it learned. The brand says it controls every step of production in its own facility, using kiln-dried solid wood, low EMF, non-toxic materials and tight seals for even heat, and cites patented SoloCarbon® infrared plus integrated red and near-infrared light. Its story page says the company grew out of the experience of Connie and Aaron Zack, whose family member's life was transformed with the help of infrared light, and that they committed themselves to growing Sunlighten and mastering infrared light.
History
Sunlighten's story page states that the company's story began over 20 years ago when Connie and Aaron Zack watched her brother's life transform with the help of infrared light, after a decade of failing to find relief from chronic fatigue, mercury poisoning and spinal injury. A dentist recommended infrared light therapy, and it changed his life; he founded Sunlight saunas to share what he had found. Inspired by his experience, the Zacks harnessed their history as pharmaceutical associates and committed everything they had to growing Sunlighten and mastering infrared light. The page also describes a Europe expansion, with the mission of carrying infrared sauna benefits into Europe led by European HQ founder Joie Risk.
