Using Light (Sunlight, Blue Light & Red Light) to Optimize Health | Huberman Lab Podcast #68

Light Interaction

Andrew Huberman explains how light, as electromagnetic energy, interacts with our bodies. He describes light's various wavelengths, from visible spectrums like blue and red to invisible ones like ultraviolet and infrared, impacting biological processes. This energy can influence everything from skin health to organ repair, with different wavelengths penetrating tissues to varying degrees 1.

Light impacts us at many different levels, and the so-called levels that I'm referring to are the different wavelengths of light.

Understanding these interactions helps us harness light's potential for health benefits 2.

   

Therapeutic Uses

Phototherapy offers promising therapeutic applications, such as pain management and mood enhancement. Andrew Huberman highlights how UVB light exposure can trigger the release of endogenous opioids in the brain, reducing pain perception 3. He suggests a protocol of 20 to 30 minutes of UVB exposure, two to three times a week, to safely harness these benefits 4.

Most of us should be getting more UVB exposure from sunlight.

Additionally, systemic light exposure, involving both skin and eyes, is more effective than localized treatments for broader health improvements 5.
