This episode is all about clearing up confusion and bringing practical advice to the world of sauna use. I brought on Connie Zack, who co-founded one of the most highly regarded infrared sauna companies, to help break down the research, technology, and best practices. We discussed questions like how hot a sauna needs to get, whether the latest gadgets and red lights are worthwhile, the real science behind detox and heat stress, and even tips for making sauna routines fit anyone’s lifestyle—whether you’re a hardcore athlete or just want to relax and recover.
Connie Zack is the co-founder of Sunlighten, the global leader in infrared sauna and light therapy and the creator of the full-spectrum, low EMF infrared sauna I use. Inspired by her brother's health transformation, she and her husband, Aaron, left successful pharmaceutical careers to revolutionize the industry with science-backed innovations.
Connie is a pioneer in infrared light technology, driving widespread education on its benefits through collaborative partnerships. A passionate advocate for holistic health, Connie integrates nutrition, exercise, mindfulness, and infrared therapy into her life. As a mother, wife, wellness enthusiast and entrepreneur, she brings light, hope and happiness to the world through her expertise in how infrared light and heat impacts healthy lifespan.
