58: Infrared Light, Sauna Science, and Personalized Wellness with Connie Zack
What happens when you look beyond temperature and start thinking about a sauna as a source of precisely delivered light and energy? In this episode of Take Back Your Health®, Dr. Amy Myers reconnects with Connie Zack, co-owner of Sunlighten and Sunlighten Day Spa, for a detailed conversation about infrared sauna technology, wavelength science, and practical ways to build a consistent wellness routine.
Connie shares the personal story that inspired her family to make infrared technology more accessible, explains the differences between steam, traditional, and infrared saunas, and breaks down the roles of far-, mid-, and near-infrared light. The conversation also explores heat shock proteins, personalized sauna use, light therapy, and the importance of evaluating wavelengths, separation, testing, and proximity when comparing products.
What You'll Learn
- How infrared saunas differ from steam and traditional heat saunas.
- Why far-, mid-, and near-infrared are discussed as distinct parts of the infrared spectrum.
- How near-infrared and red light differ in visibility, depth, and wavelength discussions.
- What Connie explains about heat shock proteins and the body’s response to controlled stress.
- Why sauna routines may be personalized around goals such as sweating, relaxation, energy, or consistency.
- How preheating may matter when the goal is sweating, while infrared energy begins as soon as the sauna is turned on.
- What to consider when evaluating light-therapy products, including wavelength, separate delivery, independent testing, patents, and proximity to the body.
- Connie’s three practical takeaways: create time for personal connection and intention, stay hydrated, and choose a consistent wellness practice that fits your needs.
