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

Neuronal Health

Red light therapy shows promise in improving neuronal health and reversing age-related vision loss. Andrew Huberman explains that red and near-infrared light can reduce reactive oxygen species and cholesterol deposits in the eye, enhancing neuronal function 1. This therapy targets the retina, which is part of the central nervous system, and can potentially reverse aging processes in neurons 1.

Viewing red light and near-infrared light at a safe distance for just a couple of minutes each day allowed a reversal of the aging process of these neurons.

The Jeffery Lab's studies highlight the potential of red light to improve vision and reduce drusen, fatty deposits in the eye, thus supporting overall neuronal health 2.

   

Practical Uses

Practical guidelines for red light therapy emphasize safety and timing. Andrew Huberman advises using red light panels early in the day, within the first three hours of waking, to maximize benefits 3. It's crucial to ensure the light is not too bright, as excessive brightness can damage the eyes, and retinal neurons do not regenerate 4.

If you look at any light source that's painful and makes you want to squint or close your eyes, that means it's too bright to look at without closing your eyes.

--- Andrew Huberman

Huberman suggests consulting an optometrist before starting any extensive protocols and highlights that commercially available panels often combine red and near-infrared light, which can be effective for enhancing neuronal function 4.
