What if the clothes you wear and the sheets you sleep on could actively support your body's natural healing processes?

In this fascinating conversation, host Sarah chats with Seth Casden from Celliant about infrared technology embedded into everyday textiles - and no, this isn't science fiction. It's science fact.

Seth shares his journey from being an amateur athlete dealing with a stubborn shoulder injury to discovering infrared saunas and eventually meeting someone developing a way to harness infrared light through fabric. That was 25 years ago, and the technology has evolved to the point where you literally can't tell the difference between a Celliant garment and a regular one - except your body can.

You'll discover:
• What infrared light actually is
• Why you can't see it but your body responds to it
• How minerals embedded in fabric absorb your body's heat and convert it back to beneficial infrared light
• Why improved circulation affects everything from sports performance to sleep quality
• The surprising connection between grip strength and longevity
• How this technology went from sports performance to bedding to potentially car seats and aeroplanes!
• Why Seth's socks became a talking point at trade shows (hint: dry feet, no odour, better circulation!)

This conversation explores the science of blood flow and circulation, how infrared wavelengths interact with our bodies at a cellular level, and why something invisible can have such tangible effects. Seth also discusses the clinical trials and research behind Celliant, including their classification as a Class 1 medical device in the EU and UK.

What makes this episode special is how accessible Seth makes complex science. He uses relatable examples to explain how infrared fits into the spectrum of things we can't see but know are there.

Whether you're an athlete looking for performance gains, someone dealing with poor circulation, struggling with sleep quality, or simply curious about wellness technology that doesn't require changing your routine, this conversation offers genuinely useful insights.

It's practical, science-backed, and surprisingly straightforward. No hype, no unrealistic claims - just clear explanation of how harnessing your body's natural heat and converting it to infrared light can support circulation, thermoregulation, recovery, and sleep.
