The Livelong Podcast
In this episode of the Livelong Podcast, Dr. Raleigh Duncan, the founder and CEO of Clearlight Infrared Saunas, joins Livelong’s Erin Hunter to explore the science of infrared light, heat exposure, and aging.
This conversation cuts through wellness hype to explain how and why light-based therapies may help reduce disease burden, support recovery, and aging. We unpack many concepts in this episode, such as the idea of passive aerobics, mitochondrial optimization, photobiomodulation, and nervous system regulation.
Dr. Duncan breaks down:
Why infrared heat works differently from traditional saunas
How light therapy supports circulation, cellular energy, and longevity
The link between stress, inflammation, and accelerated aging
Why “passive exercise” can still deliver cardiovascular benefits
How sauna rituals support nervous system regulation and emotional well-being
Why rest, consistency, and ritual matter more than intensity
Infrared…it’s the friendliest, most common thing in our world.
Whether you’re curious about infrared technology, sauna culture, longevity, or what’s really going on inside your body, this episode offers a clear look at aging and will help you come away with more insight about how to take charge of your health.
