đĽ SLEEP & SAUNA: Why heat can boost mood + nervous system resilience
In todayâs episode, our guest joins us from INSIDE his sauna (!) and stands as one of the true pioneers of infrared therapy, Dr. Raleigh Duncan. Yes⌠heâs literally recording from the sauna :) while breaking down the science behind how heat + cold can transform your sleep and nervous system.
Since November is National Sleep Comfort Month and we are all still adjusting to the time change, this conversation is all about using nightly rituals to support better sleep, overall health, and wellness so you are not tempted to crash at 7:30 pm.
Dr. Duncan, founder of and creator of the patented Carbon/Ceramic and True Wave infrared systems (which boast some of the lowest EMF/ELF levels in the industry), explains whatâs really happening when you step into the heat: your heart rate rises, your vessels open, and then your body drops into deep parasympathetic calm. Think dopamine release, muscle relaxation, and that âclear headâ feeling we all crave.
We unpack:
⢠How contrast therapy could potentially support deeper sleep
⢠Why heat can boost mood + nervous system resilience
⢠His best strategies for jet lag recovery
⢠Who should and shouldnât sauna before bed
⢠How to pair heat, cold, and breath for better nightly rest
If youâve ever wondered how to use these tools to sleep better, travel smoother, and feel more regulated, especially during National Sleep Comfort Month, this oneâs for you.
