How To Use Red Light Therapy, Infrared Saunas & Cold Plunges For Longevity, Mood & Beauty | Sunlighten’s Connie Zack

WATCH THE FULL-LENGTH EPISODE HERE ON YOUTUBE! 

Infrared therapy isn’t just a wellness trend - it’s a science-backed tool for longevity and healing at the cellular level.

In this episode, I sit down with Connie Zack, co-founder and co-CEO of Sunlighten, to explore how light, heat, and cold can transform your health from the inside out. Connie shares her family’s story - from her brother’s recovery from heavy metal toxicity to building one of the most trusted infrared brands in the world - and how Sunlighten’s technology harnesses the power of light to support detoxification, balance the nervous system, and enhance resilience.

We unpack the differences between far, mid, and near-infrared light, why bioavailability matters in light therapy, and how consistency - not intensity - drives lasting benefits. You’ll also learn how contrast therapy (the combination of heat and cold) can improve heart rate variability, lower inflammation, and elevate mood.

If you’ve ever wondered how light impacts longevity, this conversation will illuminate what’s truly possible.
