Red light therapy has exploded over the last few years, and with that growth has come a lot of confusion, misinformation, and mixed messages.
In this episode, I’m joined again by Andrew LaTour, founder of GembaRed, for an updated, grounded conversation on red light therapy, and what actually matters now in 2026.
Andrew first joined me two years ago for a deep-dive episode that became one of the most comprehensive red light therapy guides on the show. This time, we focus on safety, practicality, and clarity in a social-media-driven landscape.
We talk about what’s changed, what hasn’t, where people are getting confused, and how to use red light therapy safely and effectively without overthinking it.
This conversation also addresses common listener questions, influencer misuse, misinformation circulating online, and why simple, consistent use often matters more than “perfect” wavelengths or high-intensity devices.
In this episode, we cover:
- What red light therapy (photobiomodulation) actually does at a cellular level
- A quick grounding recap for new listeners
- Why red and near-infrared light are more flexible than people think
- The difference between wavelength, intensity, and dosing, and why they’re so often confused
- Why higher intensity doesn’t automatically mean better results
- How exposure time impacts mitochondria and ATP production
- Common safety concerns, and where they really come from
- The role influencer culture has played in misinformation and misuse
- Whether there are any body parts red light should not be used on
- Eye safety, goggles, and why proper use matters more than worry
- Why red light therapy is generally very safe when devices are made responsibly
- Practical guidance for 10-15 minute sessions and consistency
- Using red light therapy for fertility support and hair loss
- Why consumers don’t need to obsess over specs to see benefits
