There are claims that using infrared light at fairly low intensity helps to boost the mitochondria in our cells. Which (the claims are) may have various health benefits. Have a look on YouTube and search for “photobiomodulation” or LLLT (low level laser therapy). They tend to use IR LEDs now rather than lasers, hence the general term is “photobiomodulation” but there are plenty of videos / articles / papers that refer to LLLT, but it is essentially the same thing.
Anyway I have 3D printed this prototype, and am trying it on myself.
