Update: 2026-04-09
Description
Infrared saunas have gone mainstream, but most people still don't know how they work. In this episode, Jeff talks with Connie Zack, co-founder of Sunlighten, about the science behind infrared light therapy: why it penetrates the skin differently, what it does to your mitochondria, and how consistent use supports whole-body health.
We cover:
- The differences between far, mid, near infrared, and red light
- Impacts on cardiovascular health, detoxification, and brain function
- Importance of HRV, circadian rhythm, and nervous system regulation
- Beginner protocol: where to start and what to avoid
