Short interview-style video (May 2, 2023) in which Josh Trent and a guest discuss light therapy beyond sleep: effects on recovery, hormones, wellness, and a 2018 study reporting melanopsin (a blue-light photoreceptor) in skin—implying blue light to skin can affect circadian rhythm and that red light may repair blue-light cellular damage.

When did the lights come on in your head where you were like, okay, there's got to be something more to this light therapy and light therapeutics than the glasses.
We found that light impacted more than just sleep. It impacted recovery, impacted, well, being hormone levels. And we just discovered more and more ways to use light to help people in their wellness and health journeys. There's a really interesting study that came out in 2018 that found out that melanopsin, okay, which is the blue light photoreceptor thought to only be present in the eyes, is actually present in people's skin. So with this study, it shows that blue light hitting your skin will impact your circadian rhythm, regardless of whether you're wearing blue light glasses or not. So the sun's very clever, right? It emits blue light, which keeps us alert during the day. That's fantastic. But it also contains a lot of red light, which then repairs the damage that blue light causes at a cellular level.
