Summary
Host Elizabeth Benton explains the differences between red light therapy, near-infrared light, and infrared saunas, breaking down how each works and why she uses both a red light panel and an infrared sauna as part of her daily routine. She explains that infrared saunas use mid-infrared wavelengths to heat the body from the inside out (similar to a fever), triggering chemical messengers that impact metabolism, brain health, mood, and inflammation while inducing sweating as a critical detoxification pathway. Red light and near-infrared light therapy work differently by activating mitochondrial receptors to increase cellular energy production, improve blood flow, and reduce pain and inflammation. Benton shares personal results including relief from plantar fasciitis and low back pain using red light, improved skin quality, and enhanced sleep. She uses the sauna and red light separately, noting that the heat stress from the sauna can overtake the more subtle cellular effects of red light therapy. The episode also addresses the broader context of toxic exposure in modern life and practical steps for reducing toxin burden.
Key Points
- Infrared saunas heat the body from the inside out using mid-infrared wavelengths, unlike steam/rock saunas that heat the air first
- Sweating is a critical detoxification pathway; mercury and other toxins are excreted through sweat at measurable levels
- People who don't sweat easily may have impaired detoxification pathways that improve with regular sauna use over time
- Red light and near-infrared light activate mitochondrial receptors, increasing cellular energy production
- Red light therapy showed personal results for plantar fasciitis, low back pain, and skin quality improvement
- Infrared sauna and red light therapy should be used separately so heat stress doesn't overtake red light's cellular effects
- Modern toxic exposure from nanoplastics, cleaning products, and food packaging makes active detoxification essential
Key Moments
Infrared saunas heat from the inside out like a controlled fever
Elizabeth explains how infrared saunas use mid-infrared wavelengths to penetrate deep into the body and warm it from the inside, triggering chemical messengers that impact metabolism, brain health, mood, and inflammation -- functioning like a controlled fever.
"So, infrared saunas utilize generally mid-infrared wavelengths. They penetrate deep into your body and warm it from inside, kind of like a fever."
Sweating as a critical mercury detoxification pathway
Benton explains that sweating is a critical detoxification pathway, with mercury and other toxins excreted at measurable levels through sweat. She notes that people who don't sweat easily may have impaired detox pathways that improve with regular sauna use.
"Sweating is a critical pathway for detoxification, and that's what I get most excited about when I sit in my sauna. For example, mercury. We know that mercury is a toxin and a really potent toxin."
Red and near-infrared light activate mitochondria for cellular energy
Red light and near-infrared light activate mitochondrial receptors, increasing cellular energy production and improving blood flow, pain, inflammation, and skin health. These wavelengths penetrate skin more effectively than other light frequencies.
"But what these light waves do, the red light and the near-infrared light, they activate your mitochondria. We've recently talked about the mitochondria and how critical they are. They're the powerhous"
Personal results with red light for plantar fasciitis and back pain
Benton shares that red light therapy resolved her plantar fasciitis flare-ups and significantly improved her chronic low back pain from pregnancy, demonstrating practical pain relief applications.
"And the only So that's been really exciting. I also have been using it every once in a while. I have a flare-up of plantar fasciitis in my feet, which is like a kind of a tendonitis sort of situation"
