  Frankly my experience with posting sources on HN has almost never been good. It's often just taken as a reason to pick those apart and start a flamewar. My comment above has been downvoted at least 5 times which makes me confident that this is one those times. For what it's worth I have no stakes in anything and no sources at hand. I remember having read at least two different studies about this, but it has been years. I'm sure your google-fu is as good as mine so maybe you can find something.

    Surely it’s not controversial to post a scientific publication supporting your claims. I suggest you Google-fu yourself.

      A quick search turned up the following. The list is non-exhaustive and wasn't vetted in detail. 2017: Aging Retinal Function Is Improved by Near Infrared Light (670 Nm) ...

        And this site includes an interesting chart of effective light frequencies: "This chart pulled from the Joovv site shows that one of the receptors of light energy in our body, Cytochrome C Oxidase, absorbs many more photons at certain wavelengths." https://primalhacker.com/blogs/learn/red-light-photobiomodulation-buyers-guide https://primalhacker.com/blogs/learn/red-light-photobiomodul...
